| Link in email to process an ics invitation Posted: 01 May 2016 06:54 AM PDT I have implemented an invitation system in my application, that generates an ical attachment that is sent to the appropriate users. Is it possible to add a link in the email body that would trigger the processing of the invitation ? (in addition to the extra buttons provided by some email clients) This question mentions that for email attachments in the general case it's not possible. Is it still the case for icalendar attachments ? Other questions suggest using a service like https://www.addevent.com/, but this seems to be more oriented toward "public events", whereas in my case I would need something quite private (only invitations between 2 people), that are expected to be generates quite often (should be able to scale up to 100/day without problem), or it it just me getting a bad impression ? |

| How do I param the Controller Favorite Create method to have an index#view Posted: 01 May 2016 06:18 AM PDT I want to create a polymorph model to favorite each object I want to create to stock in my user page. I am developing a web app to learn japanese and we can favorite different types of cards as kanas or kanjis and sentences. So there are 3 objects and soon more to favorite. I migrated a table which names Favorite : create_table "favorites", force: :cascade do |t| t.integer "user_id" t.integer "favoritable_id" t.string "favoritable_type" t.datetime "created_at", null: false t.datetime "updated_at", null: false end
Here is the Favorite model belongs_to class Favorite < ActiveRecord::Base belongs_to :favoritable, polymorphic: true belongs_to :user end
Here are the Cards model has_many class Symbole < ActiveRecord::Base accepts_nested_attributes_for :kanji_attribute, :allow_destroy => true has_many :sentence_symboles, :class_name => "SentenceSymbole", :foreign_key => "symbole_id" has_many :favorites, as: :favoritable end
and I added in sentence model too class Sentence < ActiveRecord::Base include Authority::Abilities has_many :sentence_symboles, :class_name => "SentenceSymbole", :foreign_key => "sentence_id", dependent: :destroy has_many :favorites, as: :favoritable end
Now here is the Favorite controller and I don't really know how to write the create method. Here is the Controller I do: class FavoritesController < ApplicationController def index @favorites = Favorite.where(user: current_user) end def create #Favorite.create(user_id: User.last.id, favoritable_id: Symbole.last.id, favoritable_type:"Symbole") @favorite = current_user.favoritable.favorites.create(symbole: @symbole, sentence: @sentence).first if @favorite.present? @favorite.destroy else @favorite = current_user.favorites.new(symbole: @symbole, sentence: @sentence) if not @symbole.favorites.where(user: current_user).take @sentence.favorites.where(user: current_user).take @favorite.save end end # redirect_to favs_path # redirect_to :back respond_to do |format| format.js { render :ajax_update_favs } end end def destroy @favorite = Favorite.find(params[:id]) @favorite.destroy redirect_to :back end end
Please could someone give me the right way to favorite all object I want and add in an favorite index#view. Thank you for your help. |
| How can I add a large number of static HTML files to rails app without slowing the development cycle? Posted: 01 May 2016 06:17 AM PDT I am wondering the best way to include an old web site into a newer rails app. The legacy web site: - Has 21,000 small text files with minimal markup that are linked together.
- Totals ~ 220MB
- Has a root page located within a directory and is linked to many sub-directories
I'd like to include the old site in my rails app folder, but I am concerned that it will mean a much longer development cycle each time I deploy. I am using capistrano and my first thought is to place the folder with Old Site in the shared directory on the production server and symbolically link to it accordingly. This approach strikes me as undesirable as my resources for New App will be split in more than one location. The benefit might be a much quicker debug/deploy cycle. Right now, I have no plans to modify the Old Site files. At some point, that could change. I have been impressed with how quickly my otherwise lightweight project will deploy. Right now I am making frequent changes and repeating the code/deploy cycle often. I'd like to avoid slowing that down unnecessarily. Is there a best practice for this sort of thing? |
| wrong number of arguments (1 for 0) in the View Posted: 01 May 2016 05:49 AM PDT I understand what wrong number of arguments (1 for 0) means, but I don't understand why I am getting it for this line of code: <% if current_user.try(:email) == Join.all(:email) %> I am getting the error on Join.all(:email) Basically, what I am trying to do is check to see if the current_user.try(:email) matches any of the email for Join.all The Join method is made up of strings that are :email. Here's what my table looks like create_table "joins", force: :cascade do |t| t.string "email" t.datetime "created_at", null: false t.datetime "updated_at", null: false end
Help is much appreciated. |
| Rails Assets Pipeline load JavaScript from controllers and methods Posted: 01 May 2016 05:53 AM PDT I want to stay DRY in my code so I want to auto-load my javascripts file when it matches a controller or/and a method and the .js exists. I added this to my layout = javascript_include_tag params[:controller] if ::Rails.application.assets.find_asset("#{params[:controller]}.js") = javascript_include_tag "#{params[:controller]}/#{params[:action]}" if ::Rails.application.assets.find_asset("#{params[:controller]}/#{params[:action]}.js")
So now when I add javascripts/my_controller/my_method.js it automatically loads it, which's nice. Sadly I must add another line to precompile the asset otherwise an error is thrown (which says I must precompile my .js file) and I didn't find any way around this. Rails.application.config.assets.precompile += %w( orders/checkout.js )
Does anyone has a solution to avoid tu add manually elements in this configuration ? NOTE : I already tried to use require_tree . which was just loading all the files on every page and was not working in my case. |
| serialize a column and save Posted: 01 May 2016 06:49 AM PDT I'm using rails 4.2 with ruby 2.2. I'm trying to save some data inside a column in a hash format. I'm trying to save license details in the license column which is of text datatype, and in the respective model i've given: serialize :license, JSON
I have this in the controller: params.require(:company_detail).permit(:company_name, :trading_name, :contact_name, :acn, :address, :suburb, :state, :post_code, :phone_number, :fax_number, :nrma_approved, :start_date, :release_date , :website_url ,:email, license: {date1: :date1, license1: :license1, date2: :date2, license2: :license2, date3: :date3, license3: :license3, date4: :date4, license4: :license4})
and in form = form_for @company_detail, remote: true, html: {class: 'form-horizontal form-label-left', data: {"parsley-validate" => ""}} do |f| = f.fields_for :license do |l| .row .col-lg-6 .form-group %label.control-label.col-md-4.col-xs-12 Date 1 .col-md-8.col-xs-12 = l.text_field :date1, value: @company_detail.license.present? ? @company_detail.license["date1"] : '', class: 'date-picker form-control has-feedback-left datePicker' .col-lg-6 .form-group %label.control-label.col-md-4.col-xs-12 Licence Number 1 .col-md-8.col-xs-12 = l.text_field :license1, value: @company_detail.license.present? ? @company_detail.license["license1"] : '', class: 'form-control'
I tried entering a few fields in the form and submit, but even though the params are going in correctly, the value saved is null. This is the log: Parameters: {"utf8"=>"✓", "company_detail"=>{"license"=>{"date1"=>"121212", "license1"=>"12313", "date2"=>"122131123", "license2"=>"123123", "date3"=>"", "license3"=>"", "date4"=>"", "license4"=>""}}, "commit"=>"Save", "id"=>"1"} CompanyDetail Load (0.3ms) SELECT "company_details".* FROM "company_details" WHERE "company_details"."id" = $1 LIMIT 1 [["id", 1]] User Load (0.8ms) SELECT "users".* FROM "users" WHERE "users"."id" = $1 ORDER BY "users"."id" ASC LIMIT 1 [["id", 1]] (1.0ms) BEGIN SQL (0.4ms) UPDATE "company_details" SET "license" = $1, "updated_at" = $2 WHERE "company_details"."id" = $3 [["license", "{\"date1\":null,\"license1\":null,\"date2\":null,\"license2\":null,\"date3\":null,\"license3\":null,\"date4\":null,\"license4\":null}"], ["updated_at", "2016-05-01 12:15:44.918547"], ["id", 1]]

| Combine Ruby on Rails and AngularJS Posted: 01 May 2016 03:46 AM PDT Maybe this is a dumb question or even a common asked question (or just a lousy searcher). I want to start a new web application project using Ruby on Rails. On the other hand, I really like Angular JS with Angular Material for the form design. The have everything already implemented like an autocomplete, different types of buttons, etc. Now the question is, how to combine those two? I want to use Ruby on Rails's routing, controller, models, resource etc. but Angular Material more for the Frontend Design and catch user's actions in events. |

| Sum of all amount if created_at dates are the same in Rails Posted: 01 May 2016 05:28 AM PDT I'm trying to replicate this with the Rails database (pg) query but not having much luck. My Foo table has many columns but I'm interested in created_at and amount. Foo.all.where(client_id: 4) looks like this:
[ [0] {:created_at => <date>, :amount => 20}, [1] {:created_at => <different date>, :amount => 5}, ... ]
Stripe Charge Object is in json so I thought I could: f = Foo.all.where(client_id: 4).as_json # could I?
Anyhow, my controller: # As per first link above def each_user_foo starting_after = nil loop do f = Foo.all.where(client_id: 4).as_json #f_hash = Hash[f.each_slice(2).to_a] # I was trying something here break if f.none? f.each do |bar| yield bar end starting_after = bar.last.id end end foo_by_date = Hash.new(0) each_user_foo do |f| # Parses date object. `to_date` converts a DateTime object to a date (daily resolution). amount_date = DateTime.strptime(f.created_at.to_s, "%s").to_date # line 50 amount = f.amount # Initialize the amount for this date to 0. foo_by_date[amount_date] ||= 0 foo_by_date[amount_date] += amount end
My error at line 50 is: undefined method `created_at' for Hash I guess an object is still in an array somewhere. Also, is there an equivalent for the JS console.log() in Rails? Would be handy. |
| Rails FactoryGirl inside app in development env Posted: 01 May 2016 05:13 AM PDT I'm trying to use FactoryGirl gem inside my App in development mode (it's for mailer tests more) with rails_email_preview gem.

| Rails - Bootstrap popover js Posted: 01 May 2016 02:14 AM PDT Im trying to understand how js works in Rails. I am using bootstrap and have managed to get popovers working, but not in the way that i had understood Rails works. I currently have a partial called _preferences inside my organisations views folder. In my organisations show page, I render that partial. The partial has a button which calls a popover, as: <button class="fa fa-info-circle fa-2x fa-border btn-info" id="publicity" href="#" rel="popover" data-original-title="Publicity Issues" data-content="<%= publicity_popover(@organisation.preference)%>"></button>
I tried to make an organisations.js file that had: $('#publicity').popover() $('#academic_publication').popover() $('#presentations').popover()
but the popovers didn't work when I tried that approach. When I add the following to the bottom of the preferences partial, it all works fine. <script> $('#publicity').popover() $('#academic_publication').popover() $('#presentations').popover() </script>
I expected the first attempt to work. I can't understand why it doesnt. Does any one see the error? |

| How do you remove an actioncable channel subscription in Rails 5 with App.cable.subscriptions.remove? Posted: 01 May 2016 12:21 AM PDT To create subscriptions I run: App.room = App.cable.subscriptions.create({ channel: "RoomChannel", roomId: roomId }, { connected: function() {}, disconnected: function() {}, received: function(data) { return $('#messages').append(data['message']); }, speak: function(message, roomId) { return this.perform('speak', { message: message, roomId: roomId }); } });
But because I want the client to never be subscribed to more than one channel, what can I run each time before this to remove all subscriptions the client has? I tried to do something super hacky like: App.cable.subscriptions['subscriptions'] = [App.cable.subscriptions['subscriptions'][1, 0]]
But I'm sure it didn't work because there are many other components that go into a subscription/unsubscription. App.cable.subscriptions.remove requires a subscription argument, but what do I pass in? Thanks! |
| How to create a record from the belongs_to association? Posted: 01 May 2016 12:42 AM PDT I have this association: user.rb class User < ActiveRecord::Base has_many :todo_lists end
todo_list.rb class TodoList < ActiveRecord::Base belongs_to :user end
And I'm trying to understand the following behavior: todo_list = TodoList.create(name: "list 1") todo_list.create_user(username: "foo") todo_list.user #<User id: 1, username: "foo", created_at: "2016-05-01 07:09:05", updated_at: "2016-05-01 07:09:05"> test_user = todo_list.user test_user.todo_lists # returns an empty list => #<ActiveRecord::Associations::CollectionProxy []> test_user.todo_lists.create(name: "list 2") test_user.todo_lists => #<ActiveRecord::Associations::CollectionProxy [#<TodoList id: 2, name: "list 2", user_id: 1, created_at: "2016-05-01 07:15:13", updated_at: "2016-05-01 07:15:13">]>
Why #create_user adds user to todo_list (todo_list.user returns the user), but does not reflect the association when user.todo_lists is called? |

| How can I implement in Rails bid offers that sellers can cancel or accept within 24hrs or transaction is cancelled? Posted: 01 May 2016 12:00 AM PDT I am working on a marketplace in rails that allows buyers to make an offer to the seller as a bid for a product. The seller can cancel or accept the bid but only has a 24 hr window to do this or the bid expires and the transaction is cancelled. How can the transaction for bids be implemented. The hardest part is actually figuring out creating the timer in rails. I also thought about some sort of boolean functionality to inform the seller if the bid status is pending or cancelled or accepted but that becomes three possible values that can not work in a true or false situation. Any help in any of these problems would be greatly appreciated. |

| How to run a command automatically after each reboot Posted: 30 Apr 2016 10:15 PM PDT I currently have Ubuntu 16.04 installed on my virtual box. I installed Ruby and Rails by RVM. After that I tried $ rails
The terminal said The program `rails` is currently not installed. You can install it by typing: sudo apt install ruby-railties
I solve this problem by typing $ source ~/.rvm/scripts/rvm
Credits here However, once I reboot the virtual machine, everything I did with source will lose and I need to re-enter $ source ~/.rvm/scripts/rvm
I also have some similar cases I need to do on every reboot. So is there any solution can make those command be run automatically each time? |
