Rails - show facebook post after admin acceeptation Posted: 05 Sep 2016 07:43 AM PDT I want to put facebook posts from my facebook page on my rails website, but they will be shown on the www after admin acceptation. I thought about creating table in mysql with facebook posts (link to post, visible) so the admin could change the 'visible' field to true/false. Will Koala gem help me with it? And facebook graph api? Maybe should I try it different way? Any ideas and tips will be very helpful

Performance wise will iOS extension files help in rendering big assets faster ? Posted: 05 Sep 2016 07:42 AM PDT We have a mobile app that builds its UI , partly via large video / animation files. Today we apply calls to our server to retrieve these assets . The problem is that the app's graphics is loading instantly aside for these assets that are loading ... We are thinking of moving these large assets from where they are today ( on our servers ) to be part of the extension files ( up to 4 GB ) that appstore / google play offer. Question is : from your experience, will this change help render these big assets faster to the client? Thanks

rails filter each method on results page Posted: 05 Sep 2016 07:42 AM PDT So i have this filter on the results page of my application <div class="panel panel-default" style="margin-top: 10px"> <div class="panel-heading" style="color: #fff; background-color: #1292fd; font-weight:bold">Search Filters</div> <div class="panel-body" style="color: #1292fd; font-weight:bold"> <label for="datefrom">Date From:</label> <input type="date" id="datefrom" class="form-control" name="date" value="dd/mm/yyyy"> <label for="dateto">Date To:</label> <input type="date" id="dateto" class="form-control" name="date" value="dd/mm/yyyy"> <hr> <div style="float:right"> <button class="btn btn-info" name="button">Apply Filters</button> </div> </div> </div> Just a simple date from to filter. What i'm wanting to do is have the results in the each method which is above it filtered between the two dates selected. i'm under the impression i would need something like this: Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day) My controller looks like this at the moment: def search @events = Event.page(params[:page]).per(10).search(params[:search], misspellings: { distance: 1 }, order: { date: :asc, eventname: :asc }, match: :word_start, page: params[:page], per_page: 20) if @events.results.any? render 'events/results' else render 'events/noresults' end end So at the moment im unaware how to get the results to filter with the filter option. any help is appreciated Sam

Unique constraint issue paranoia gem Posted: 05 Sep 2016 07:15 AM PDT I have a rails app in which i am using devise and paranoia gems. I have a users table in postgres db which has unique validation on email column. I am using paranoia for soft delete, issue is when i delete a user and then tey to create a user using the email of the deleted user it throws an error PG::UniqueViolation: ERROR. I have read about this and know that this could be solved using partial index feature of rails. http://scottsmerchek.com/2015/08/03/taking-the-d-out-of-crud/ https://devcenter.heroku.com/articles/postgresql-indexes#partial-indexes How do i implement this? Sorry for bad formatting, typing from mobile.

Error localhost:3000 - Errno::ECONNREFUSED at /courses Posted: 05 Sep 2016 07:00 AM PDT So I'm trying to preview a page with courses and I get this error: Connection refused - {:data=>"fq=type%3ACourse&fq=hidden_b%3Afalse&sort=university_sponsor_b+desc%2C+university_partner_b+desc%2C+score+desc%2C+score+desc%2C+name_s+asc&start=0&rows=15&q=%2A%3A%2A", :method=>:post, :params=>{:wt=>:ruby}, :query=>"wt=ruby", :headers=>{"Content-Type"=>"application/x-www-form-urlencoded; charset=UTF-8"}, :path=>"select", :uri=>#http://localhost:8982/solr/development/select?wt=ruby>, :open_timeout=>nil, :read_timeout=>nil, :retry_503=>nil, :retry_after_limit=>nil}

Using Statesman with Racsack to return particular states from dropdown Posted: 05 Sep 2016 06:39 AM PDT How do I use Ransack (with a dropdown menu of the states from Statesman) to return a subset of data from my collection? Example; Here is my dropdown; <select class="select" name="q[state_machine_current_state_eq]" id="q_state_machine_current_state_eq"> <option selected="selected" value="pending">pending</option> <option value="active">active</option> </select> A record can either be "pending" or "active". Here is my controller index method; def index @filter = current_sponsor .card_holders .ransack(params[:q]) @sponsor_card_holders = @filter .result .page(params[:page]) .per(3) .decorate end If I do a binding.pry now I can get this for @filter; Ransack::Search<class: User::CardHolder, base: Grouping <combinator: and>> For @sponsor_card_holders.first.current_state "active" For params[:q] <ActionController::Parameters {"state_machine_current_state_eq"=>"active"} permitted: false> I think my issue is almost certainly the state_machine_current_state_eq part in my dropdown html. I've basically made an educated guess. I also tried current_state_eq. I am expecting it to return something like; Ransack::Search<class: User::CaseWorker, base: Grouping <conditions: [Condition <attributes: ["card_holder_state_machine"], predicate: eq, values: ["active"]>]> But it's ignoring the dropdown. What is the correct syntax?

Ruby on Rail app with Cloud9 and Postgres Posted: 05 Sep 2016 06:46 AM PDT I have a simple application on "Ruby on Rails" with "Active admin-gem" for the users authentification, I am trying to create a PostgreSQL database on C9, I have seen many tutorials but none works for me So I have so far: Installation postgres gem - gem 'pg' Start the Postgresql on C9 Create database with name "mydatabase" Generate the user 'ubuntu' password 'ubuntu' Ubuntu is the owner of "mydatabase" Configuration of "database.yml" My database.yml now, but i tried with others: default: &default adapter: postgresql encoding: unicode host: localhost pool: 5 database: mydatabase username: ubuntu password: ubuntu development: <<: *default test: <<: *default production: <<: *default Error when i use: $ rake db:create DEPRECATION WARNING: Passing a string to ActiveRecord::Base.establish_connection for a configuration lookup is deprecated, please pass a symbol (:postgresql) instead.

Multiple selected data doesn't appear Posted: 05 Sep 2016 06:17 AM PDT I use select2 for multiple select. My problem is, I can select multiple value from json data and I can save this data in related model columns. But when I want to update this model, the selected data doesn't appear. some part of my json data: { - categories:[ - { id:7, name:"Eğitim Bilimleri Enstitüsü" }, - { id: 8, name: "Eğitim Yönetim Teftişi ve Planlaması 1. Yarıyıl" }, ... ] } I have a Moodle class(it is not inheritance from ActiveRecord, just a class and it has some functions which return json data). I wonder whether it is right approach. in the content of my form: <%= simple_form_for(@period) do |f| %> ... <%= f.input :moodle_connect_ids, collection: Moodle.categories.map {|p| [ p['name'], p['id'] ] }, input_html: {multiple: true} %> ... <% end %> I explicitly set moodle_connect_ids to be an array in my controller: params.require(:period).permit(..., :moodle_connect_ids => []) in the content of my .js file: $("#period_moodle_connect_ids").select2({ placeholder: "Moodle Dönem Bağlantılarını Seçiniz", multiple: true, allowClear: true }); When I select to multiple values and save my model, the column's value looks like this: > Period.last => #<Period:0x007fcf53a4d830 id: 25, ... moodle_connect_ids: "[\"\", \"85\", \"120\"]" ... Am I on the wrong way? Have you any suggestion?

Rails 5 , render a form without specific input Posted: 05 Sep 2016 05:49 AM PDT I am trying to render a partial form for editing but i don't want a specific part of that form to show up in the edit action.

RoR - The record failed to save when after its foreign key was set to nil Posted: 05 Sep 2016 06:26 AM PDT I'm trying to solve this problem of mine. I'll tell you what I did, where I struggle and hopefully you can lend me a hand. I'm kinda new to this Rails thing and get hopefully 1-2 good tips regarding my problem. That would be really awesome. Problem: LocationsController request to edit should load the requested location Failure/Error: @location.image = @image ActiveRecord::RecordNotSaved: Failed to remove the existing associated image. The record failed to save when after its foreign key was set to nil. LocationsController request to edit should be successfull Failure/Error: @location.image = @image ActiveRecord::RecordNotSaved: Failed to remove the existing associated image. The record failed to save when after its foreign key was set to nil. Part of the Controller: def new @location = Location.new end def create @location = Location.new(params[:location]) @location.owner_id = current_user.id @address = Address.new(params[:address]) @location.image = Image.new(params[:image]) responds_to_parent do if @location.save && @location.image.update_from_uploaded_data(params[:image]) @address.addressable = @location @address.save @locations = Location.all_as_select_options respond_to do |format| format.js { render layout: false } end else render :update end end end def edit @address = @location.address end def update @location.image ||= Image.new @location.address ||= Address.new address = params[:address] if @location.update_attributes(params[:location]) && @location.address.update_attributes(address) && @location.image.update_from_uploaded_data(params[:image]) flash[:notice] = 'Daten für den Ort wurden geändert.' redirect_to location_path(@location) else flash[:notice] = 'Die Daten konnten nicht gespeichert werden' render action: 'edit' end end def destroy @location.destroy if @location.owner.id == current_user.id redirect_to action: 'index', controller: 'locations' end private def load_location @location = Location.find(params[:id]) end Rspec: describe 'request to edit' do before do login(mock_admin) @location = create_location @image = create_image Location.stub!(:find).and_return(@location) Image.stub!(:find).and_return(@image) @location.image = @image get :edit, id: @location.id end it 'should be successfull' do response.should be_success end it 'should load the requested location' do assigns(:location).should eql(@location) end it 'should load the locations address' do assigns(:address).should eql(@location.address) end end My attempt: Allowing parameters like location and image in my edit method. Like it was suggested at Can't update my nested model form for has_one association I tried the 'params.require(:...).permit(...)' and accepts_nested_attributes_for(:..., update_only: true) solution which were suggested. But even with all parameters allowing it didn't work out. Do you know why though? I tried to modify the methods but o well... Edit -- -- Model: class Location < ApplicationRecord belongs_to :owner, class_name: '::User', foreign_key: 'owner_id' has_one :address, as: :addressable, :dependent => :destroy has_one :image, as: :visualisable has_many :events validates_presence_of :owner_id, :name def display_name [name.to_s, address&.display].compact.join(', ') end def self.all_as_select_options all.collect { |m| [m.name, m.id] } end def can_be_deleted_by?(user) owner == user && events.count == 0 end end

Routing Error uninitialized constant SubmitsController (Trying to upload document using Carrierwave) Posted: 05 Sep 2016 06:01 AM PDT I am building my first useful Rails application for a teacher to post assignments and students to upload their work (jpeg|pdf) on the website using Carrierwave.

Rails 4 cascade save association with validation on belongs_to Posted: 05 Sep 2016 05:41 AM PDT I'm having troubles autosaving objects which are created this way. Consider having following models: class SearchTerm < ActiveRecord::Base has_many :search_term_occurrences, dependent: :destroy end class SearchTermOccurrence < ActiveRecord::Base belongs_to :search_term validates :search_term, presence: true # Problematic validation end So when I try to do the following: term = SearchTerm.new term: 'something' term.search_term_occurrences << [SearchTermOccurrence.new, SearchTermOccurrence.new] term.save! I get the following: ActiveRecord::RecordInvalid: Validation failed: Search term occurrences is invalid, Search term occurrences is invalid But when I omit the validation on belongs_to search_term. Everything is saved properly. My question is: How to save parent object and its association (newly created) whilst having validations on child objects without saving associated objects one by one and then saving parent object within transaction? I want Rails to handle the transactional logic.

disable input on checkbox in rails app Posted: 05 Sep 2016 05:09 AM PDT I have a date input dropdown on a form in my rails application. I'd like there to be a checkbox that- when checked/selected by the user- will (#1) disable the date input and (#2) populate the date input with the current date. I've looked at previous SO answers to get an idea of how to do this and here's what I tried to accomplish #1: app/assets/javascripts/application.js //= require jquery //= require bootstrap //= require jquery_ujs //= require turbolinks //= require_tree . $(document).on('change', '#availableNow', function(){ debugger; if($(this).prop('checked')){ $('#fromDatePicker').attr('disabled', 'disabled'); } else { $('#fromDatePicker').removeAttr('disabled'); } }); In the form... app/views/apartments/_form.html.erb <div class="field"> <%= f.label :available_now %> <%= f.check_box :available_now, id:"availableNow" %> </div> <div class="field"> <%= f.label :to_date %><br> <%= f.date_select :to_date, {:include_blank => true, :default => nil, :start_year => Date.today.year, :end_year => Date.today.year + 4, :order => [:month, :day, :year] }, id:"fromDatePicker" %> </div> Rails generates 3 dropdown menus for the date picker (day, month & year). Only month (the first dropdown) is disabled when the box is checked. Any ideas how to get the checkbox functionality to work for all the dropdowns? Any idea how to "grey out" the dropdowns once they are disabled? Thanks in advance!

assert_template fails after switching to Polymorphic Associations Posted: 05 Sep 2016 06:26 AM PDT It is probably something silly simple but I simply can not figure it out. Here is my situation: after adding a new db I realized that it would be the best to change an already existing one, so that it now uses polymorphic associations. Of course after I changed it, pretty much everything else went to hell. I managed though to fix all but one minor problem. The integration test now fails and I simply dont know why since the page itself still works perfectly fine... def setup @user=users(:michael) @clip=clips(:Michi_clip_one) log_in_as(@user) end test "successful edit" do get edit_clip_path(@clip) assert_template "clips/edit" .... FAIL["test_successful_edit", ClipEditTest, 2.686249095015228] test_successful_edit#ClipEditTest (2.69s) expecting <"clips/edit"> but rendering with <[]> test/integration/clip_edit_test.rb:13:in `block in <class:ClipEditTest>' Since I really have no idea where lies the problem, I will simply add a few things of which I think that they might be related. Michi_clip_one: adress: "nfWlot6h_JM" owner: michael description: "MyText" . class Clip < ApplicationRecord belongs_to :owner, polymorphic: true default_scope -> { order(created_at: :desc) } validates :adress, presence: true, uniqueness: {scope: :owner} before_save { self.adress=adress.split("=").last } validates :owner, presence: true end . class ClipsController < ApplicationController before_action :logged_in_user, only: [:new, :destroy, :edit, :update, :create] before_action :correct_user, only: [:destroy, :edit, :update] def edit @clip=current_user.clips.find_by(id: params[:id]) end If you need other lines of code to figure the problem out, I'll be happy to add it.

Ruby on Rails: Why doesn't my embedded image display in Gmail or Office 365? Posted: 05 Sep 2016 03:45 AM PDT I'm trying to embed images within HTML emails so that they display inline, but for some reason the image does show in Outlook software but not in Gmail (online) or Office 365 (online). I have been referring to http://api.rubyonrails.org/classes/ActionMailer/Base.html as well as the SO question What is the right way to embed image into email using Rails? And my code is the following: environments/development.rb and production.rb: config.action_mailer.asset_host = "http://localhost:3000" Email view: <%= image_tag('logo.jpg') %> This displays the image in Outlook: But not in Gmail or Office 365: In the log I get the following img src for this: <img src="http://localhost:3000/assets/logo-9b88158fa35240340cc52aa5d01800b12e6e1de5ddb99e246bd0583c7a5611cd.jpg" alt="Logo" /> I have tried a variety of approaches from different people, which include the SO questions: Unable to render inline attachments in ActionMailer Rails attachments inline are not shown correctly in gmail Send HTML emails with inline images with ActionMailer But none of them seem to solve my issue. The code I have tried is: (Attempt 1) Mailer: def send_email(email, unsubscribe) @url = 'http://localhost:3000/users/login' @email = email @unsubscribe = unsubscribe attachments.inline['logo.jpg'] = File.read('C:/Sites/MySite/app/assets/images/logo.jpg') mail(from: "#{@email.from_name} <#{@email.account.email}>", to: @email.to, cc: @email.cc, bcc: @email.bcc, subject: @email.subject, message: @email.message) end Email View: <%= image_tag attachments['logo.jpg'].url -%> Log: <img src="cid:57cd4b6a997ae_25703efc6dc786d@My-Laptop.mail" /> ----==_mimepart_57cd4b6a9af1e_25703efc6dc78787 Content-Type: image/jpeg; filename=logo.jpg Content-Transfer-Encoding: base64 Content-Disposition: inline; filename=logo.jpg Content-ID: <57cd4b6a997ae_25703efc6dc786d@My-Laptop.mail> QzovU2l0ZXMvRWFzeU1haWwvYXBwL2Fzc2V0cy9pbWFnZXMvbG9nby5qcGc= ----==_mimepart_57cd4b6a9af1e_25703efc6dc78787-- (Attempt 2) Mailer: def send_email(email, unsubscribe) @url = 'http://localhost:3000/users/login' @email = email @unsubscribe = unsubscribe # THE BELOW LINE attachments.inline['logo.jpg'] = File.join(Rails.root, 'app/assets/images/logo.jpg') mail(from: "#{@email.from_name} <#{@email.account.email}>", to: @email.to, cc: @email.cc, bcc: @email.bcc, subject: @email.subject, message: @email.message) end Email View: <%= image_tag attachments['logo.jpg'].url -%> (Attempt 3) Mailer: def send_email(email, unsubscribe) @url = 'http://localhost:3000/users/login' @email = email @unsubscribe = unsubscribe attachments.inline['logo.jpg'] = { :data => File.read('C:/Sites/MySite/app/assets/images/logo.jpg'), :mime_type => "image/jpg", :encoding => "base64" } mail(from: "#{@email.from_name} <#{@email.account.email}>", to: @email.to, cc: @email.cc, bcc: @email.bcc, subject: @email.subject, message: @email.message) end Email View: <%= image_tag attachments['logo.jpg'].url -%> This gives me a UTF error (Attempt 4) Mailer: def send_email(email, unsubscribe) @url = 'http://localhost:3000/users/login' @email = email @unsubscribe = unsubscribe attachments.inline["logo.jpg"] = { mime_type: "image/jpg", content: Base64.encode64(File.read(Rails.root.join("app/assets/images/logo.jpg"))) } mail(from: "#{@email.from_name} <#{@email.account.email}>", to: @email.to, cc: @email.cc, bcc: @email.bcc, subject: @email.subject, message: @email.message) end View: <%= image_tag "data:image/jpg;base64,#{attachments['logo.jpg'].url}" %> Log: <img src="data:image/jpg;base64,cid:57cd4c32e96d0_25704cedd5878982@My-Laptop.mail" /> ----==_mimepart_57cd4c32ea670_25704cedd5879035 Content-Type: image/jpg Content-Transfer-Encoding: base64 Content-Disposition: inline; filename=logo.jpg Content-ID: <57cd4c32e96d0_25704cedd5878982@My-Laptop.mail> aVZCT1J3bz0K ----==_mimepart_57cd4c32ea670_25704cedd5879035-- But none of these seem to work, its also worth adding that only the code at the top shows the image in Outlook, all the others stop me from seeing the image in Outlook, Gmail, and Office365. Can someone please help me with this issue as I can't make sense of it. I am using Rails 4.2.6

Rails and MySQL - structure Product with sizes and prices Posted: 05 Sep 2016 03:30 AM PDT What is the proper way to structure models and migrations in Rails so I can have relationships like this: I think the image is clear enough but: One product can have different sizes A size can have different prices dependent on the product it is associated with. I am in a school project and the only guy who has ever done something with code, and we need to structure something similar to this (it's biological but the idea is the same). Would generating: For product: rails generate model Product name:string class Product < ApplicationRecord has_many :sizes has_many :prices end For size: rails generate model Size size:string product:references class Size < ApplicationRecord has_many :products has_many :prices end For price: rails generate model Price price:decimal size:references product:references class Price < ApplicationRecord has_many :sizes has_many :products end solve my problem? I am in the middle of reading this but it is not helping.

How to allow users to define arbitrary number of fields in Rails Posted: 05 Sep 2016 03:09 AM PDT I'm building a CMS where Administrators must be able to define an arbitrary number fields of different types (text, checkboxes, etc). Users then can fill those fields and generate posts. How can this be done in Rails? I guess that the persistence of these "virtual" attributes will be done in a serialised attribute in the database. But I am not sure how to struct the views and controllers, or where the fields should be defined.

Why is the link_to code adding same comment twice? Posted: 05 Sep 2016 02:55 AM PDT I am trying to use JavaScript with jquery in rails to update a div without reloading the page. Its working but the comment is being created twice. I know something is wrong in the form partial but couldn't figure it out. Any help? The following are the files - _new_comment.html.erb <%= form_for [:home, Comment.new], :url => home_comments_path, :html => {:id => "comment-new-" + post.id.to_s} do |f| %> <div> <%= f.text_area :message, :class => "message-area-" + post.id.to_s, :placeholder => "Add comment..." %> <%= f.hidden_field :post_id, :value => post.id %> <span class="new-comment"><%= link_to 'Add', '#', remote: true, :onclick => "$('#comment-new-#{post.id}').submit()" %></span> </div> <% end %> comments_controller.rb def create @comment = Comment.new(comment_params) @comment.user_id = current_user.id if @comment.save flash[:notice] = 'Comment added sucessfully' respond_to do |format| format.html { redirect_to home_posts_url } format.js end end end create.js.erb $("#comment-new-83").before('<div class="notice"><%= escape_javascript(flash[:notice]) %></div>'); $("#comment-new-83")[0].reset(); home.js jQuery.ajaxSetup({ 'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")} }) $(document).ready(function() { $("#comment-new-83").submit(function() { $.post($(this).attr("action"), $(this).serialize(), null, "script"); return false; }) })

How to get the user that published the comment and time it was created from the database so I can present it to the view Posted: 05 Sep 2016 03:22 AM PDT I'm creating a forum. I have successfully created a Post model presenting posts in the html view with the user email and created_at time. I have also created a Comment model for replying to posts. I've been following a tutorial and understand most of it, but am lost in now getting the user and created_at values of the comments from the database so I can display them. Even though I did it with the post model, it's different because I'm using partials that display in the show html view from the Post controller, and it's confusing me that both the post and comments are displaying in the post controller show view. (i.e. the comments don't have their own show view). I'm a newbie. Any help would be appreciated. Thank you. routes.rb Rails.application.routes.draw do devise_for :users resources :posts do resources :comments end root 'posts#index' end Migration for create_comments class CreateComments < ActiveRecord::Migration[5.0] def change create_table :comments do |t| t.text :comment t.references :post, foreign_key: true t.references :user, foreign_key: true t.timestamps end end end comments_controller.rb class CommentsController < ApplicationController def create @post = Post.find(params[:post_id]) @comment = @post.comments.create(params[:comment].permit(:comment)) @comment.user = current_user if @comment.save redirect_to post_path(@post) else render 'new' end end end _form.html.haml = simple_form_for([@post, @post.comments.new]) do |f| = f.input :comment = f.submit models/comment.rb class Comment < ApplicationRecord belongs_to :post belongs_to :user end show.html.haml #post_content %h1= @post.title - if user_allowed_post = link_to "Delete", post_path(@post), method: :delete, data: { confirm: "Are you sure you want to delete this?"}, class: "button" = link_to "Edit", edit_post_path(@post), class: "button" - else %br %br %br %p= @post.content %p Published = time_ago_in_words(@post.created_at) by = @post.user.email #comments %h2 - if @post.comments.size == 1 = @post.comments.size Comment - else = @post.comments.size Comments = render @post.comments %h3 Reply to thread = render "comments/form" Let me know if you need any other files or info.

word.charAt is not a function, Datatable error Posted: 05 Sep 2016 03:50 AM PDT I have integrated datatable in my Rails app (4.2.4) like this: application.js //= require datatables.js //= require ../metronic/assets/global/plugins/datatables/media/js/jquery.dataTables.js //= require ../metronic/assets/global/plugins/datatables/media/js/dataTables.bootstrap.js An example of use is the index page: <table id="students" class="datatable table table-striped table-hover table-datatable"> <thead> <tr> <th class="left">Nome</th> <th class="left">Cognome</th> <th class="left">Classe</th> <th class="left">Codice Fiscale</th> <th class="left">Indirizzo</th> <th class="left">Email</th> <th class="left">Cellulare</th> <th/> </tr> </thead> <tbody> <% @students.each do |student| %> <tr> <td class="left"><%= student.nome %></td> <td class="left"><%= student.cognome %></td> <td class="left"><%= student.sigla_classe%></td> <td class="left"><%= student.codice_fiscale %></td> <td class="left"><%= student.indirizzo %></td> <td class="left"><%= student.email %></td> <td class="left"><%= student.cell %></td> <td class="right"> <%= link_to 'Vedi', student %> | <%= link_to 'Modifica', edit_student_path(id: student) %> | <%= link_to 'Elimina', student, style:'color:#F00;', method: :delete, data: { confirm: 'Sei sicuro?' } %> </td> </tr> <% end %> </tbody> </table> This is the controller: def index @students = Student.all respond_to do |format| format.html format.pdf do pdf = StudentPdf.new(@students, view_context) send_data pdf.render, filename: 'Elenco Studenti', type: 'application/pdf', disposition: 'inline' end end end If I do a search, the error disappears, I just can not figure out what I did wrong, I do not think it was wrong in the index are almost sure that the error lies in the way in which I integrated datatables. For the rest everything works, the table is well displayed with correct pagination.

Modern architecture for Rails (and React) [on hold] Posted: 05 Sep 2016 02:06 AM PDT I am building simple SaaS app with web presentation like Home, Pricing, Features etc and then the complicated part with User Authentication & Dashboard and lots of back-end codes. Web presentation: I've done the web presentation with a simple demo with some little back-end code. It's running on Rails 5 and I am using ActionCable there with background jobs. User Dashboard: I wanna build now the user authentication and the complicated features - User Dashboard, some DB tables etc. I decided to use React with Rails. Hosting on Heroku. Question: How the modern SaaS applications work? Should I keep it separate and create own Heroku/Rails app for just the presentation and own for user dashboard to make it simple? Is there anything I could be aware with this idea? -- I am also kind of new with React and single-page-apps. How could I build modern applications with React and Rails in the backend? Should I have a look for Flex or Redux? Should I process all the data with API and json? Should I be aware of anything? How would you build modern SaaS app in Rails?
