| Rails: Assets in manifest file are loaded always? Posted: 10 Jul 2016 07:12 AM PDT The assets required in manifest file app/assets/javascripts/application.js are loaded for all pages? I realized that a script made for me which does something every 5 seconds was being executed in all pages, so now I am not sure if when one requires a script into manifest file, this is loaded in all pages, even if is include just in one view. My manifest file: // app/assets/javascripts/application.js //= require jquery //= require_tree loading/loader
My regarding view: / some code = javascript_include_tag "/loading/loader"
But the script is executed even in the home. |
| How do I install bootstrap js? Posted: 10 Jul 2016 07:20 AM PDT I followed the hartl rails book to install the bootstrap css files, but I believe I'm missing the javascript to go with it. Here's what the book told me to do: - add
bootstrap-sass to the Gemfile: gem 'bootstrap-sass' - run bundle install
add the following to the css: @import "bootstrap-sprockets"; @import "bootstrap";
What else do I need to do to add the javascript portion? |
| Rails ecommerce site session Posted: 10 Jul 2016 07:06 AM PDT I have worked through the book Agile Development with Rails 4. I deployed the app using heroku. I only have a login feature for administrators and so anyone can create a cart and submit an order without making an account. I noticed that when i create a cart on my laptop on the deployed website that the cart is the same when i go to my desktop. So there is one cart with say id = 20 shared among all sessions. This is obviously a problem. I suspect it has to do with my module for current_cart but not sure. module CurrentCart extend ActiveSupport::Concern private def set_cart @cart = Cart.find(session[:cart_id]) rescue ActiveRecord::RecordNotFound @cart = Cart.create session[:cart_id] = @cart.id end end
I then use include CurrentCart and before_action:set_cart on the store, orders, line items, and carts controllers. I would like each session to be associated with each computer and end upon closing the browser, which I know can vary with the browser settings. I believe this might also be happening because I am storing this information in the database so the cart_id persists until the cart is deleted. Any help would be appreciated. |

| Rails 4: Pass attribute's value into the model for dynamic vailidation Posted: 10 Jul 2016 06:23 AM PDT In my 'Entry' model... class Entry < ActiveRecord::Base
...I am trying to pass an attribute's value directly into the data validation below (the attribute that will dynamically update is ':wpu', and the value is an integer based on the user's form submission. There are three user options from a drop-down menu the will submit a value for ':wpu'; for the sake of this conversation, consider the value either '5', '10', or '20'). validates :text, length: { is: DYNAMIC_VALUE_WOULD_GO_HERE, tokenizer: lambda { |str| str.squish.gsub('&'){''}.scan(/\w+/) } }
This validates when the string attribute's word count ':text' is equal to the integer of the other attribute mentioned earlier, ':wpu'. The code above works perfect if I replace the 'DYNAMIC_VALUE_WOULD_GO_HERE' with a '5', '10', or '20', but I haven't been successful in placing a dynamic value in there based on a user's input. I've worked on this thing--probably has a simple answer--for 3 days now, but with no success. Things I have tried: 1) Using attr_reader and calling the attributes value 2) Passing controller method parameters to the model I am open to any suggestions and other methods. I am a beginner in ruby and rails. Here is my full model code as it stands. It doesn't currently work as I haven't been able to pass through 'params'. Otherwise, without trying to make this dynamic, everything works fine if I remove the random experimental method below. class Entry < ActiveRecord::Base belongs_to :story attr_reader :wpu #method used to generate 'wpu' | which is words per user in Story def self.storywpu #story ID from EntriesController current_entry_story_id = Entry.find(params[:id]).story_id #returns 'wpu' | which is words per user in Story storywpu = Story.find(current_entry_story_id).wpu return storywpu end #strips ALL white space before form submission auto_strip_attributes :text, :nullify => false, :squish => true #validates each field has been filled out validates :user_id, presence: true validates :story_id, presence: true validates :text, presence: true, autocomplete: false #validates word count is exactly 'wpu' | which is words per user in Story validates :text, length: { is: self.storywpu, tokenizer: lambda { |str| str.squish.gsub('&'){''}.scan(/\w+/) } } end
And here is a related portion of my controller for reference... class EntriesController < ApplicationController before_action :set_entry, only: [:show, :edit, :update, :destroy] def create #New text entry @entry = Entry.create(entry_params) #Related story params @story = Story.find(@entry.story_id) @storyWPU = Story.find(@entry.story_id).wpu @word_count = @entry.text.squish.gsub('&'){''}.scan(/\w+/).size.to_i @wordsLeft = @storyWPU - @word_count if @word_count.nil? @response = 'enter ' + @wordsLeft.to_s + ' words' elsif @wordsLeft == 1 @response = 'enter ' + @wordsLeft.to_s + ' word' elsif @wordsLeft < 0 @response = @wordsLeft.abs.to_s + ' too many!' else @response = 'enter ' + @wordsLeft.to_s + ' words' end respond_to do |format| if @entry.save format.html { redirect_to edit_story_path(@story), notice: 'Nice!' } format.json { render :show, status: :created, location: @entry } else format.html { redirect_to edit_story_path(@story), notice: @response } format.json { render json: @entry.errors, status: :unprocessable_entity } end end end private def set_entry @entry = Entry.find(params[:id]) end private def entry_params params.require(:entry).permit(:text, :user_id, :story_id, :wpu) end end

| Redirect not working in Ruby on Rails Posted: 10 Jul 2016 07:47 AM PDT I have two models, one that is called Timelines and other called Contests. class Contest < ActiveRecord::Base belongs_to :member belongs_to :timeline end class Timeline < ActiveRecord::Base belongs_to :member end
While I am inside http://localhost:3000/timelines/1 this path for instance I have a button that when I click it I want to make a redirection to create a new contest. <button type="button" onclick="setContest(0)">Before</button> function setContest(type){ $.ajax({ url: '/contests/new', type: 'GET', data: { "before": type, "timeline_id": $("#timeline_id").text(), "video_id": $("#video_id").text() } }).success(function(d){ location.replace(d.new_path); }).fail(function(err){ alert(err.value); }); }
But when I click it I got the following error: ActiveRecord::RecordNotFound in TimelinesController#show Couldn't find Timeline with 'id'=undefined # Use callbacks to share common setup or constraints between actions. def set_timeline @timeline = Timeline.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through.

| ActiveRecord::Rollback doesn't seems to do a transaction rollback Posted: 10 Jul 2016 05:14 AM PDT One day I noticed my transactions dont accept a ActiveRecord::Rollback.

| Refactor controller action code DRY Posted: 10 Jul 2016 05:48 AM PDT I am using indeed_api to retrieve jobs from Indeed API, but because Indeed only allows 25 results per query, i have come up with this code in my controller to get all jobs and list them all on one page: @jobs = IndeedAPI.search_jobs(co: "au", l: "sydney", radius: "100", sort: "date", limit: "25") @results = @jobs.results if @jobs.total_results > 25 @jobs2 = IndeedAPI.search_jobs(co: "au", l: "sydney", radius: "100", sort: "date", start: "25", limit: "25") @results += @jobs2.results end if @jobs.total_results > 50 @jobs3 = IndeedAPI.search_jobs(co: "au", l: "sydney", radius: "100", sort: "date", start: "50", limit: "25") @results += @jobs3.results end if @jobs.total_results > 75 @jobs4 = IndeedAPI.search_jobs(co: "au", l: "sydney", radius: "100", sort: "date", start: "75", limit: "25") @results += @jobs4.results #and so on...
This is rather ugly and definitely not a rails way to do it. I mean, the controller could spread out to hundreds of lines. Is there a way to put this code in a loop or refactor it in any other way? |

| Link to tab in other page using link_to in rails 4 Posted: 10 Jul 2016 04:50 AM PDT How do you link to a different page and activating a tab using link_to from the scaffold generated code. <%= link_to t('.cancel', :default => t("helpers.links.cancel")), root_path, :class => 'btn btn-default' %>
i tried this but it didn't work either: <%= link_to t('.cancel', :default => t("helpers.links.cancel")), root_path('#panel_projects'), :class => 'btn btn-default' %>
Where as #panel_projects is the tab link which i want the users to get to after getting redirected. Does anybody know how to accomplish this? Preferably without Javascript. |

| I need to create a dropdown menu in Rails for tshirt sizes that are varying in stock Posted: 10 Jul 2016 02:39 AM PDT I need to create a dropdown menu for varying tshirt sizes, some of the sizes stock are 0, so if the item has 0 stock it would not show up or be blank etc. I am loading the data from a csv in Rails.

| Create associated records when creating a user with Devise taking an attribute for the associated record Posted: 10 Jul 2016 05:37 AM PDT I have a user model and through the model membership, it has many organizations: class User < ActiveRecord::Base has_many :memberships has_many :organizations, through: :memberships end class Membership < ActiveRecord::Base belongs_to :user belongs_to :organization end class Organization < ActiveRecord::Base has_many :memberships has_many :users, through: :memberships end
During the signup process, I want to ask for the name of my organization, so, my form looks like this: = simple_for_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| = devise_error_messages! = f.simple_fields_for :memberships do |fm| = fm.input :kind, as: :hidden, input_html: {value: Membership::OWNER} = fm.simple_fields_for :organization do |fo| = fo.input :name, required: false, label: "Organization" = f.input :name = f.input :email = f.input :password = f.input :password_confirmation
and my custom strong params definition in my custom Devise registration controller looks like this: def configure_sign_up_params devise_parameter_sanitizer.permit(:sign_up) do |u| u.permit(:email, :password, :password_confirmation, memberships: {organizations: [:name]}) end end
When I submit the form, I get this error: Membership(#70355446274100) expected, got Array(#70355394078720)
on Devise's create controller action. The parameters look like this: {"utf8"=>"✓", "authenticity_token"=>"...", "user"=> {"memberships"=> {"kind"=>"owner", "organizations"=>{"name"=>"Organization name"}}, "name"=>"User's Name", "email"=>"email@address.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up"}
If I add accepts_nested_attributes_for :memberships accepts_nested_attributes_for :organizations
to the user model or if I add: accepts_nested_attributes_for :memberships
to the user model and accepts_nested_attributes_for :organizations
to the membership model, the membership and organization simple disappear for the form, they are not rendered. Even when my new registration controller action looks like this: def new super resource.memberships.build.build_organization end
I also tried defining my strong params as this: def configure_sign_up_params devise_parameter_sanitizer.permit(:sign_up) do |u| u.permit(:email, :password, :password_confirmation, memberships_attributes: [:id, organization_attributess: [:id, :name]]) end end
and it (obviously) made no difference in the HTML input field not appearing. What am I missing? How can I make this work? In regards to this question being a duplicate of Expected ProductField, got array issue , nowhere in that question or answers is the matter of forms addressed, which I am addressing here. |

| Rails + ionic : input from ionic to rails backend = Can't verify CSRF token authenticity 400 bad request Posted: 10 Jul 2016 01:18 AM PDT I have an app both in ionic and rails. the idea is to have the rails as the backend, and ionic as the interface.

| View rails record details in bootstrap modal on row click Posted: 09 Jul 2016 11:18 PM PDT I have been stuck on this problem for quite some time now and looked through several posts as well, however I cannot achieve exactly what I want for my Rails application. Essentially, I want to be able to click on a table row on my page and have a modal pop up which displays all the information for that specific record. Here are the scenarios which I have thought of/attempted partially: - Set the data-link attribute in table row with some JS as follows
HTML: <tr data-link="<%= kid_path %>"> ... </tr>
JS: $("tr[data-link]").dblclick(function() { window.location = $(this).data("link") })
This worked fine to open the show path page generated by the scaffold, but I was not able to modify it to work with a modal and have the same data for the kid in the modal. - Use data-id and JavaScript to load onto the modal
HTML: <tr data-id="<%= kid.id %>"> ... </tr>
JS: $(function () { $('#showModal').modal({ keyboard: true, backdrop: "static", show: false, }).on('show', function () { }); $(".table-striped").find('tr[data-id]').on('click', function () { debugger; $('#showDetails').html($('<p>' + 'Kid ID: ' + $(this).data('id') + '<%= Kid.find(30).first_name %>' + '</p>')); $('#showModal').modal('show'); }); });
In this approach I am able to load the modal on row click and am able to access the Kid ID, however I cannot move further to access other attributes of the record. For example, I want to set @Kid = kid.find(id) using JS where id would be the extracted ID from the row. And then, I want to be able to write the generic modal template which displays other elements (ex. kid.first_name, kid.last_name, etc). I am totally stuck and cannot find any approach that helps to accomplish my goal. Any help is appreciated, thank you. |
| Associations in Rails 4 Posted: 09 Jul 2016 11:21 PM PDT I am developing a web application for task management using ruby on rails. I have two models user and task. The models look like this class User < ActiveRecord::Base has_many :tasks devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable def role?(role_name) role == role_name end def self.assigned_user(task_params) User.where("name = ?", task_params["assigned_to"]) end end class Task < ActiveRecord::Base belongs_to :user end
what i want is assign task to user when a task is created. But i don't know how to do it in create action of tasks_controller. My create action looks like this def create @task = Task.new(task_params) respond_to do |format| if @task.save @user = User.assigned_user(task_params) @user.tasks << Task.last format.html { redirect_to @task, notice: 'Task was successfully created.' } format.json { render :show, status: :created, location: @task } else format.html { render :new } format.json { render json: @task.errors, status: :unprocessable_entity } end end end
Whenever admin assigns a task when its created, it gives an error saying undefined method tasks for #<User::ActiveRecord_Relation:0x007fe7b1c60610>. Does anyone can help what can be the problem with this? |
| Rails, search with Ransack gem, downcase a string Posted: 09 Jul 2016 10:54 PM PDT I am trying to write a search form for my shops using ransack. Currently, I can search using the name_or_address_cont option which looks EITHER in the name OR in the address. If I had a shop Adidas in London and I type Adidas London there would be no results. Therefore I looked for a way to concatenate the two attributes and search by the new one. What I found in some old posts was the following code: ransacker :search_name, :formatter => proc {|v| UnicodeUtils.downcase(v) } do |parent| Arel::Nodes::NamedFunction.new('LOWER', [Arel::Nodes::NamedFunction.new('concat_ws', [' ', parent.table[:name], parent.table[:address], parent.table[:id]])] ) end
Which is supposed to search by a shop's name, address, and id. However, when I run I get an error in the UnicodeUtils. I tried changing it to v.downcase! but I get another error. Any idea how to handle this problem? Thank you! |
| Is it possible to convert the complex SQL into rails? Posted: 10 Jul 2016 12:38 AM PDT SPEC I need to pick all rooms that don't have a single day with saleable = FALSE in the requested time period(07-09 ~ 07-19): I have a table room with 1 row per room. I have a table room_skus with one row per room and day (complete set for the relevant time range). The column saleable is boolean NOT NULL and date is defined date NOT NULL SELECT id FROM room r WHERE NOT EXISTS ( SELECT 1 FROM room_skus WHERE date BETWEEN '2016-07-09' AND '2016-07-19' AND room_id = r.id AND NOT saleable GROUP BY 1 );
The above SQL query is working, but I wonder how could I translate it into Rails ORM. |

| Cloudinary image transformation parameters not working in Rails app Posted: 09 Jul 2016 09:47 PM PDT Here's the code: = link_to (cl_image_tag(post.image_url, width:640, quality:30, class: "img-responsive")), post_path(post)
As mentioned here, this should give me an image with quality set to 30, but I'm not seeing the change in quality of the images on the site. I've tried different values for quality ranging from 10 to 100 but I'm not seeing even a slight difference. I also tried other parameters, for example, format: "jpg", which is supposed to force convert all non-jpg files to jpg, but it isn't working either. The width param works fine, by the way. |

| Rails app javascript stopped working in production Posted: 09 Jul 2016 08:44 PM PDT My blog page works fine in development environment,but stopped work in production environment. The HTML code: <div class="col-md-2" id="quicktags-block"> <div id="quicktags" class="pull-right"> <script type="text/javascript">edToolbar('article_body_and_extended', '#<TextFilter:0x00000006d24de8>');</script> </div> </div>
This code was used to show the rich text editor. In development environment ,the code is like this: function edToolbar(which, textfilter) { get_buttons(textfilter); document.write('<div id="ed_toolbar_' + which + '" class="btn-toolbar"><div class="btn-group-vertical">'); for (i = 0; i < extendedStart; i++) { edShowButton(which, edButtons[i], i); } for (i = extendedStart; i < edButtons.length; i++) { edShowButton(which, edButtons[i], i); } if (edShowExtraCookie()) { document.write( '<input type="button" id="ed_close_' + which + '" class="btn btn-default" onclick="edCloseAllTags(\'' + which + '\');" value="Close Tags" />' + '<input type="button" id="ed_spell_' + which + '" class="btn btn-default" onclick="edSpell(\'' + which + '\');" value="Dict" />' ); } else { document.write( '<input type="button" id="ed_close_' + which + '" class="btn btn-default" onclick="edCloseAllTags(\'' + which + '\');" value="Close Tags" />' + '<input type="button" id="ed_spell_' + which + '" class="btn btn-default" onclick="edSpell(\'' + which + '\');" value="Dict" />' ); } // edShowLinks(); document.write('</div></div>'); edOpenTags[which] = new Array(); }
In production environment,the code is different: function edToolbar(e, t) { for (get_buttons(t), document.write('<div id="ed_toolbar_' + e + '" class="btn-toolbar"><div class="btn-group-vertical">'), i = 0; i < extendedStart; i++) edShowButton(e, edButtons[i], i); for (i = extendedStart; i < edButtons.length; i++) edShowButton(e, edButtons[i], i); edShowExtraCookie() ? document.write('<input type="button" id="ed_close_' + e + '" class="btn btn-default" onclick="edCloseAllTags(\'' + e + '\');" value="Close Tags" /><input type="button" id="ed_spell_' + e + '" class="btn btn-default" onclick="edSpell(\'' + e + '\');" value="Dict" />') : document.write('<input type="button" id="ed_close_' + e + '" class="btn btn-default" onclick="edCloseAllTags(\'' + e + '\');" value="Close Tags" /><input type="button" id="ed_spell_' + e + '" class="btn btn-default" onclick="edSpell(\'' + e + '\');" value="Dict" />'), document.write("</div></div>"), edOpenTags[e] = new Array }
To my knowledge,the production script is just the compressed script of development environment, but why the definition of the function have been changed? And at the same time why this function does not work in production? |
| rails ajax-datatables-rails empty table Posted: 09 Jul 2016 08:13 PM PDT Im kinda new to web development so sorry if I'm missing something obvious, usually I dig until I find an answer but this time I had no luck. I'm trying to integrate ajax-datatables-rails with Rails 4.2.6 and bootstrap 3 but when I load the page I get an empty table, I was following the tutorials but I don't seem to find something more recent than the rails cast or something that clues me where I'm wrong. view (index.html.erb) <table id="paciente-table" data-source="<%= pacientes_path(format: :json) %>"> <thead> <tr> <th>Paterno</th> <th>Materno</th> <th>Nombre</th> <th colspan="3"></th> </tr> </thead> <tbody> </tbody> </table>
pacientes_datatables.rb include AjaxDatatablesRails::Extensions::Kaminari class PacientesDatatable < AjaxDatatablesRails::Base def initialize(view) @view = view end def sortable_columns # Declare strings in this format: ModelName.column_name @sortable_columns ||= %w('paciente.nombre', 'paciente.paterno', 'paciente.materno') end def searchable_columns # Declare strings in this format: ModelName.column_name @searchable_columns ||= %w('paciente.nombre', 'paciente.paterno', 'paciente.materno') end private def data records.map do |record| [ record.nombre, record.paterno, record.materno ] end end def get_raw_records Paciente.all end # ==== Insert 'presenter'-like methods below if necessary end
pacientes_controller.rb def index respond_to do |format| format.html format.json { render json: PacientesDatatable.new(view_context) } end end
pacientes.js.coffeescript $ -> $('#paciente-table').dataTable processing: false serverSide: true ajax: $('#paciente-table').data('source') pagingType: 'full_numbers'
I followed the ajax-datatables-rails tutorials on setting up with a mysql db |
