How to inherit from Devise Controllers Posted: 25 Sep 2016 07:29 AM PDT I have a user model which uses Devise for authentication and also have an administrator model, which also uses Devise. I want administrators to be able to edit users profile via administrators/users/{user.id}/edit, however I want this process to be done through Devise Controllers, therefore I tried to inherit from the Users::RegistrationsController as shown below: class Administrators::UsersController < Users::RegistrationsController before_action :set_user, only: [:show,:edit,:update,:destroy] def index @users=User.all end def show end def new super end def update @user.update(user_params) redirect_to [:administrators,:users] end but I get the following error: Could not find devise mapping for path "/administrators/users". This may happen for two reasons: 1) You forgot to wrap your route inside the scope block. For example: devise_scope :user do get "/some/route" => "some_devise_controller" end 2) You are testing a Devise controller bypassing the router. If so, you can explicitly tell Devise which mapping to use: @request.env["devise.mapping"] = Devise.mappings[:user] I tried to change the routes but I still get the same error. Could you please help me?

Why rails mailer renders emails with wrong locale? Posted: 25 Sep 2016 07:22 AM PDT The whole application is set to the right locale, while emails render with default :en (English). Any particular reason? .. Even if I move some Devise emails into partials - it starts rendering them with default locale.

Rails 4: Listening for Post Notifications Posted: 25 Sep 2016 07:21 AM PDT I've setup a Purchase Model & Purchases Controller to allow users buy Items from my Rails application via PayPal (IPN). Everything works fine apart from listening for PayPal's IPN answer. Opening PayPal in new Tab with Button => works Passing necessary Item information to PayPal => works Buy Item with PayPal => works List item as :status => "Completed" in Database => does not work! User Model: has_many :purchases Purchase Model: class Purchase < ActiveRecord::Base belongs_to :tool belongs_to :user def paypal_url(return_path) values = { business: "merchant@example.com", cmd: "_xclick", upload: 1, invoice: id, amount: tool.price, item_name: tool.title, notify_url: "http://5947992e.ngrok.io/hook" #Test Server } "#{Rails.application.secrets.paypal_host}/cgi-bin/webscr?" + values.to_query end end Purchases Controller: class PurchasesController < ApplicationController def new @purchase = Purchase.new(:tool_id => params[:tool_id], :user_id => current_user.id) if @purchase.save redirect_to @purchase.paypal_url(purchase_path(@purchase)) else render :new end end protect_from_forgery except: [:hook] def hook params.permit! # Permit all Paypal input params status = params[:payment_status] if status == "Completed" @purchase = Purchase.find(params[:invoice]) @purchase.update_attributes(status: status, transaction_id: params[:txn_id], purchased_at: Time.now) @purchase.save! @user = @tool.user @user.earned_money += @tool.price @user.save! end render nothing: true end end Routes: post "/purchases/:id" => "purchases#show" post "/hook" => "purchases#hook" Item Show View (haml): = link_to image_tag('paypal.png'), new_purchase_path(:tool_id => @tool.id), target: "_blank" Thanks in advance for each answer! Please tell me if you need additional information.

Random ActiveRecord with where and excluding certain records Posted: 25 Sep 2016 07:50 AM PDT I would like to write a class function for my model that returns one random record that meets my condition and excludes some records. The idea is that I will make a "random articles section." I would like my function to look like this Article.randomArticle([1, 5, 10]) # array of article ids to exclude Some pseudo code: ids_to_exclude = [1,2,3] loop do returned_article = Article.where(published: true).sample break unless ids_to_exclude.include?(returned_article.id) do

No route matches [#{env['REQUEST_METHOD']}] #{env['PATH_INFO'].inspect} Posted: 25 Sep 2016 06:47 AM PDT I have a Rails 5 API-only application that happens to have a static public directory. I was getting a weird error so I decided to remove everything from public except index.html which has only the following contents: hello I'm running an integration test that looks like this: require 'rails_helper' feature 'Books', js: true do scenario 'list page' do visit '/' expect(page).to have_content('hello') end end When I run my test, I get the following error: Failure/Error: raise ActionController::RoutingError, "No route matches [#{env['REQUEST_METHOD']}] #{env['PATH_INFO'].inspect}" ActionController::RoutingError: No route matches [GET] "/favicon.ico" I don't understand why I'm getting this error because nowhere am I telling it I want a favicon. Doing grep -ir 'favicon' app turns up nothing. When I visit localhost:3000 in the browser, there are no errors. Why am I getting this error and how can I fix it?

Rails active record::not found using friendly id and slug recognition Posted: 25 Sep 2016 07:53 AM PDT ive set up my rails app to use friendly_id and paperclip and i've added the slug column to the 'designs' database table using a migration. When I create a new design post and upload my image (using paperclip) the slug column is not updated when I check the database and then I get an active record error, saying the following: Here are my code snippets: Model: class Design < ApplicationRecord attr_accessor :slug extend FriendlyId friendly_id :img_name, use: [:slugged, :finders] has_attached_file :image, styles: { :thumb => ['100x100#', :jpg, :quality => 70], :preview => ['480>', :jpg, :quality => 70], :large => ['800>', :jpg, :quality => 30], :retina => ['1200>', :jpg, :quality => 30] }, :convert_options => { :thumb => '-set colorspace sRGB -strip', :preview => '-set colorspace sRGB -strip', :large => '-set colorspace sRGB -strip', :retina => '-set colorspace sRGB -strip -sharpen 0x0.5' } validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/ end Controller: class DesignsController < ApplicationController before_action :find_design, only: [:show, :edit, :update, :destroy] before_action :authenticate_user!, except: [:index, :show] def index @designs = Design.all.order("created_at desc") end def new @design = Design.new end def create @design = Design.new(design_params) if @design.save redirect_to @design, notice: "Hellz yeah, Steve!

Rails ActiveRecord: Saving nested models is rolled back Posted: 25 Sep 2016 06:16 AM PDT I've created the simplest example I can think of to demonstrate the issue: parent.rb class Parent < ApplicationRecord has_many :children accepts_nested_attributes_for :children end child.rb class Child < ApplicationRecord belongs_to :parent end Create parent, save, create child, save (works) Using rails console, creating a new parent, then saving, then building a child from the parent, then saving the parent, works fine: irb(main):004:0> parent = Parent.new => #<Parent id: nil, created_at: nil, updated_at: nil> irb(main):005:0> parent.save (0.5ms) BEGIN SQL (0.4ms) INSERT INTO `parents` (`created_at`, `updated_at`) VALUES ('2016-09-25 13:05:44', '2016-09-25 13:05:44') (3.2ms) COMMIT => true irb(main):006:0> parent.children.build => #<Child id: nil, parent_id: 1, created_at: nil, updated_at: nil> irb(main):007:0> parent.save (0.5ms) BEGIN Parent Load (0.5ms) SELECT `parents`.* FROM `parents` WHERE `parents`.`id` = 1 LIMIT 1 SQL (0.7ms) INSERT INTO `children` (`parent_id`, `created_at`, `updated_at`) VALUES (1, '2016-09-25 13:05:52', '2016-09-25 13:05:52') (1.3ms) COMMIT => true Create parent, create child, save (doesn't work) However, if I try to create a new parent, then build the child without saving the parent, and finally save the parent at the end, the transaction fails and is rolled back: irb(main):008:0> parent = Parent.new => #<Parent id: nil, created_at: nil, updated_at: nil> irb(main):009:0> parent.children.build => #<Child id: nil, parent_id: nil, created_at: nil, updated_at: nil> irb(main):010:0> parent.save (0.5ms) BEGIN (0.4ms) ROLLBACK => false Can anyone explain why, and how to fix? This is using Rails 5.

Allocate daily sales to date created Posted: 25 Sep 2016 06:26 AM PDT Im trying to gather all sales made within a week and put each sale in day made. If Moday was two sales, then Monday => {...}, {...} etc "Monday" would be ruby's date format. In my db I have 5 sale objects: Two sales on Monday and two on Tuesday. Controller: def daily_customer_sale(created) date_and_id = Sale.where('created_at >= ?', created).pluck(:created_at, :id) date_and_id.each do |obj| yield(obj.first, obj.last) end end def daily_sales(created=nil) sales_by_date = Hash.new(0) daily_customer_sale(created) do |date, id| s_date = date.to_date sales_by_date[s_date] = Sale.find(id) # Seems to return only one object per day end return sales_by_date end For views: daily_sales(1.week.ago.to_datetime) What I get in two dates (correct) in which each data has only one object when it should be two or more per date. Is there something wrong?

Rails 4: How to test Controller Action Posted: 25 Sep 2016 05:55 AM PDT How do I actually test this Controller Action, I wrote in my PurchasesController: protect_from_forgery except: [:hook] def hook params.permit! # Permit all Paypal input params status = params[:payment_status] if status == "Completed" @purchase = Purchase.find(params[:invoice]) @purchase.update_attributes(status: status, transaction_id: params[:txn_id], purchased_at: Time.now) @purchase.save! @user = @tool.user @user.earned_money += @tool.price @user.save! end render nothing: true end preferably with my Rails Console? Routes: post "/purchases/:id" => "purchases#show" post "/hook" => "purchases#hook"

Can you configure Rails to warn you when migrations result in data loss? Posted: 25 Sep 2016 05:44 AM PDT Things like removing a column result in data loss in Rails. Can you configure it to warn you of these situations (and possibly stop the migration if this happens)? I know Entity Framework does this by default.

Best design for extending class to add ToJson() method Posted: 25 Sep 2016 05:21 AM PDT I have a Java class that reads an input stream of "records" and creates a List of Record objects with the record attributes as instance fields. The Record class has a toString() method listing out the values for printing. It implements an Interface which is used by other classes. As an example, the input stream might be obtained from a File. Assume that I want to build a JavaScript app that would present a File browser, select a file, then use an extension of the above Java class to get List of Record objects from the file returning the objects as an array of Json objects via a toJson() method on the Objects and List. to present in a jQuery DataTable. Since Json is a particular representation of the data and some other representation might be XML or CSV, what is the best design to provide for these choices without affecting the original interface? What is the best way to reference the new Java class from jQuery or JavaScript, or from Ruby on Rails, for example. Do I need a servlet, or a web service?

What does the 3rd line of code from the below snippet does? Posted: 25 Sep 2016 05:13 AM PDT def create chef = Chef.find_by(email: params[:email]) if chef && chef.authenticate(params[:password]) **session[:chef_id] = chef.id** flash[:success] = "You logged In" redirect_to recipes_path else flash.now[:danger] = "Check your email or password" render 'new' end end What does session[:chef_id] = chef.id do? Is that session[:chef_id] a kind of variable or something? To which the id of a chef is assigned? Can I use some other name there?

Illegal key size: possibly you need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files for your JRE Posted: 25 Sep 2016 04:59 AM PDT I am using jruby with rails . I have installed JDK7 on my machine. Whenever I start my rails server and try to run my app I am getting error as "Illegal key size: possibly you need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files for your JRE" I searched on the google and found that I have to download JDK-7 security policy files. So I downloaded these file from here and put these files into my java directory path "C:\Program Files\Java\jdk1.7.0_79\jre\lib\security" . I thought this will resolve my problem but still I am getting same error. while pasting files in the java's security folder i am getting alert box with information as "you will need to provide administration permission to copy this folder". i cliked on continue button of alert box and file got copied. I must be missing something. Please help

Humanizer human validation not working on Devise user seperate actions, Rails 4 Posted: 25 Sep 2016 04:17 AM PDT I have Rails 4 app with Devise. Recently, I discovered that for some actions Humanizer function is not working.

web-console is not working in all views on Rails 5 Posted: 25 Sep 2016 04:17 AM PDT To have web-console available on all pages (not just the error pages), I added the following line: <%= console %> in app/views/layouts/application.html.erb The problem is that the web-console shows up in all pages, except for pages from a certain controller. When checking the view-page-source, it is also not there (so it is not hidden or something like that). I'm running in development mode using Ruby 2.3.1 on Rails 5.0

mails from my rails app are getting clipped after installing premailer-gem Posted: 25 Sep 2016 04:10 AM PDT My rails app sends out mails every day using the whenever gem. I recently installed premailer-rails gem to separate the styling from html page of the mails.Now all the mails that are sent out say they are clipped and when I click on the "view message" from the inbox I am able to see the mail contents.As far as I know messages in gmail get clipped if they exceed 102kb. Here is my layout for mailer doctype html html head title example meta name="viewport" content="width=device-width, initial-scale=1" = stylesheet_link_tag 'application', media: 'all', 'data- turbolinks- track' => true = javascript_include_tag "application", 'data-turbolinks-track' => true = render 'layouts/shim' body = yield Here is my mailer.html.slim .mail-information-container .col-md-12.col-sm-12.col-xs-12.heading h2.pull-left.margin-0 | Daily Report .col-md-12.col-sm-12.col-xs-12 .intro-container.margin-tp-5 .date =Time.now.to_date.strftime("%d %B %Y") .message | Hello there.

Michael Hartl RoR tutorial, navigation bar chapter 5 not aligning Posted: 25 Sep 2016 04:30 AM PDT I'm trying to go through Michael Hartl's (brilliant) Ruby on Rails tutorial, but I have a problem in chapter 5. The navigation bar in the header aligns vertically and aligns to the left, and not horizontally and to the right. My header (_header.html.erb) looks like this: <header class="navbar navbar-fixed-top navbar-inverse"> <div class="container"> <%= link_to "sample app", '#', id: "logo" %> <nav> <ul class="nav navbar-nav navbar-right"> <li><%= link_to "Home", '#' %></li> <li><%= link_to "Help", '#' %></li> <li><%= link_to "Log in", '#' %></li> </ul> </nav> </div> </header> and in the Gemfile I have gem 'rails', '5.0.0.1' gem 'bootstrap-sass', '3.3.6' gem 'sass-rails', '5.0.6' The questions been asked before (like here) but those were with older versions of RoR and of no help to me. Anyone got an idea?

How to get this nested form to create a new object Posted: 25 Sep 2016 05:03 AM PDT My Rails 5 application includes two models, Activity and Timeslot. activity.rb class Activity < ApplicationRecord belongs_to :club has_many :timeslots, :dependent => :destroy accepts_nested_attributes_for :timeslots validates :club_id, presence: true validates :name, presence: true, length: { maximum: 50 } end timeslot.rb class Timeslot < ApplicationRecord belongs_to :activity validates :time_start, presence: true validates :time_end, presence: true validates :day, presence: true #validates :activity_id, presence: true (I realised this was causing one of the errors I had) default_scope -> { order(day: :asc) } end When I create my activity, I'd also like to create it's first timeslot on the same page, same form. new.html.erb <%= form_for(@activity) do |f| %> <%= render 'shared/error_messages', object: f.object %> <div class="field"> <%= f.label :name, "Class name" %>* <%= f.text_field :name, class: 'form-control' %> <%= f.fields_for :timeslots do |timeslots_form| %> <%= timeslots_form.label :time_start, "Start time" %> <%= timeslots_form.time_select :time_start %> <%= timeslots_form.label :time_end, "End time" %> <%= timeslots_form.time_select :time_end %> <%= timeslots_form.label :day %> <%= timeslots_form.select :day, (0..6).map {|d| [Date::DAYNAMES[d], d]} %> <% end %> </div> <%= f.submit "Create class", class: "btn btn-primary" %> <% end %> My edit/update version of this seems to be working fine. activities_controller.rb class ActivitiesController < ApplicationController ... def new @activity = Activity.new @activity.timeslots.build end def create @activity = current_club.activities.build(activity_params) #@activity.timeslots.first.activity_id = @activity.id (I thought this might solve the problem, but didn't) if @activity.save flash[:success] = "New class created!" redirect_to activities_path else render 'new' end end def edit @activity = current_club.activities.find_by(id: params[:id]) @activity.timeslots.build end def update @activity = current_club.activities.find_by(id: params[:id]) if @activity.update_attributes(activity_params) flash[:sucess] = "Class updated!" redirect_to edit_activity_path(@activity) else render 'edit' end end ... private def activity_params params.require(:activity).permit(:name, :active, #active is set to default: true :timeslots_attributes => [:id, :time_start, :time_end, :day, :active]) end end But whenever I try to create a new activity I get the error message "Timeslots activities must exist". I feel it's trying to assign the activity_id for timeslot before the activity is created, but I'm not sure. I've tried many things (some of which I've included in my example in comment form) but am unable to work out why I'm getting this error.

Updating current_user attribute to true from password update controller action Posted: 25 Sep 2016 05:00 AM PDT My Rails 5 App only permits an admin or support user to create a user, when the user is created a password is generated and emailed to the user, on the first user login the app forces them to change the password. I have a password_updated field in my schema that I want to be filled to true when the password is updated, however I am hitting a wall here, not sure if its coder eye and I just cant see what where im going wrong. my application controller: # Force User To Change Password On First Login def after_sign_in_path_for(resource) if current_user.password_updated == "false" edit_passwords_path else authenticated_root_path end end I have it set up so that if the user tries to skip or jump past the password change they are redirected to the password change. my passwords controller: class PasswordsController < ApplicationController def edit @user = current_user end def update if current_user.update_with_password(user_params) current_user.password_updated = "true" flash[:notice] = 'Your Password Has Been Sucessfully Updated.' redirect_to authenticated_root_path else flash[:error] = 'Oh No! Something Went Wrong, Please Try Again.' render :edit end end private def user_params params.require(:user).permit(:password_updated, :current_password, :password, :password_confirmation) end end Originally I had the application controller looking at the sign in count, however if the user closed out and waited long enough they could log back in and not have to change the password. I felt this was more of a risk. Any assistance here would be greatly appreciated.

Using rake db:migrate to create tables in database in mysql. Command appears successful, but databases have no tables Posted: 25 Sep 2016 03:19 AM PDT I've been tasked with working on a Ruby on Rails web application and have been given a laptop to work on it. I've managed to grab the source code and get the website up and running on the laptop, however, I can't seem to get rails to communicate fully with mysql. The issue is that when I try to setup the database using rake commands all appears well until I go and check on the database. I can see that the databases from the database.yml file are created, but the migrated tables are not, even though during the migrate command they appear to be. I've tried several times recreating the database and re-running the commands, and have even recreated the project, but still have not been able to get the tables to generate.

Sum of Table atributes when value is string Posted: 25 Sep 2016 04:24 AM PDT I've never come across this before. I'm working with a table attribute whos value is a string, not float/int. Model.first.amount => "58.00" I need to sum up all amount. What I'm used to, with the amount being a float, would be: Model.all.sum(&:amount) => # total value Took a wild guess with: Model.all.sum(&:amount.to_i) # undefined method `to_i' for :amount:Symbol Is there a clean way to sum up the amount? Or convert the database to float?

Search in Rails ==> But it only talks about getting the search to work correctly for the title, no mention of the body http://railscasts.com/episodes/111-advanced-search-form/ ==> This one sorta had what I was looking for but this seemed a lot more difficult to me, not simply searching for through another column of the row in the table; searching the Body column instead of Title column. I've tried adding different methods to the Article.rb model, Articles_controller.rb, but I'm just shooting in the dark; any suggestions Stack family? Your help would be greatly appreciated! Thanks! =)

Can't Start Rails Server, ActiveAdmin Probably Has Issues Posted: 25 Sep 2016 01:53 AM PDT I installed ActiveAdmin to manage the Admin end of my Rails app and everything was absolutely fine till I generated a model for ActiveAdmin. Now the rails server fails to start, even Rake Rollback or rails d active_admin:resource MyModel doesn't work. I am clueless now, might be a simple stupid error but still I can't figure it out, BTW here's the error dump. /home/ubuntu/workspace/app/admin/products.rb:1:in `<top (required)>': uninitialized

Rails 5 Create, Update and Delete won't work when trying to save Posted: 25 Sep 2016 03:02 AM PDT I am trying apply CRUD in rails but it didn't save any records for example, I have a model (database table) called Subject and it only has 2 fields (id, title). This is the code when I'm trying to create a record: >> subject = Subject.create(:id => 'Comp1', :title => 'Word Processing') (0.0ms) BEGIN #<Subject id: "Comp1", title: "Word Processing"> (0.0ms) ROLLBACK the data only saved on an object, but not in the database, here is my code when i am trying to use the new/save >> subject = Subject.new #<Subject id: nil, title: nil> >> subject.id = 'Comp1' "Comp1" >> subject.title = 'Word Processing' "Word Processing" >> >> subject.save (0.0ms)BEGIN (0.0ms)ROLLBACK false I know that when i use the create method it will save automatically in the database, but in my case it wasn't. when I used subject.errors, this is the result >> subject.errors #<ActiveModel::Errors:0x00000006b0d230 @base=#<Subject id: "Comp1", title: "Word Processing">, @messages={:course_group=>["must exist"]}, @details={:course_group=>[{:error=>:blank}]}> maybe it is because the subject_id is a foreign key inside course_group table. All I want is to add data to the subjects table without adding to the course_group table

Precompile assets without loading entire rails stack Posted: 25 Sep 2016 01:40 AM PDT In a rails application you can configure in application.rb which assets need to be precompiled. Then you have to run rake assets:precompile, which loads the entire rails stack. Is it possible to precompile assets without loading anything from rails and/or my application? (apart from the gem dependencies that sprockets has). Reason I ask is because I fail to see why I have to install all gems, including stuff like mysql, only to precompile assets? I wish it was more decoupled.

Start a dowload from external link in Rails Posted: 25 Sep 2016 03:15 AM PDT I'm trying to write code in my controller download to start a download from some external url say www.abc.com/foo.mp4. So far I have built it this way: def download redirect_to 'www.abc.com/foo.mp4' end It works but the problem is that it opens a video in the same tab. What I want is that it should start a download in the browser of this video. I searched about it in forums but couldn't find any solution. All I found was a way to download the video first using the URL and then provide it as download but that's not what I want. I want the download to start directly from the external URL.
