| Docker - run two processes in single container Posted: 12 Nov 2016 07:48 AM PST I've created Ruby on Rails project with Nginx. Rails app and Nginx runs in separate and linked containers. This configuration works fine. However... 1) Is it possible to run both together (Rails / Puma server + Nginx) in a single container? 2) How should the CMD command in Dockerfile look like? 3) What command should I use as the "command:" attribute in docker-compose.yml? I think that configuration to run them in separate containers is better solution, but I would like to get to know all possibilites. I use Puma as a Rails' app server and to run it I use command: bundle exec puma -C config/puma.rb |
| Serialize nested attributes in Rails? Posted: 12 Nov 2016 07:44 AM PST So I have models like this: folder, up_file has 1 chat_roomchat_room belongs to crmable with polymorphic: true (so 1 chat_room may belongs to folder or 1 up_file)chat_room has many commentscomment belongs to chat_room and user (who posted the comment) I've defined all relationship like this: class Folder < ApplicationRecord has_one :chat_room, as: :crmable, dependent: :destroy end class UpFile < ApplicationRecord has_one :chat_room, as: :crmable, dependent: :destroy end class ChatRoom < ApplicationRecord belongs_to :crmable, polymorphic: true has_many :comments, dependent: :destroy has_many :users, through: :comments end class Comment < ApplicationRecord belongs_to :chat_room belongs_to :user end
This setup worked fine with my web app. However, I'm writing API for this app, and I can't get that nested associations serialized with this gem https://github.com/rails-api/active_model_serializers
I've follow their tutorial here but my associations not rendered. class FolderSerializer < ActiveModel::Serializer attributes :id, :name, :ancestry, :creator_name #... my other attributes has_one :chat_room, include: [ :id, comments: :user ] # ^ I tried to serialize folder's chat_room with all it comments, along with these comments' users. end
All I got is this - chat_room association not serialized?

| Pass results from loop into a form_tag Posted: 12 Nov 2016 06:41 AM PST In my ruby on rails application, I am trying to take results from an API (OMDBapi) call (response in JSON) and then display the results in a view. This is working as expected. In this case its a list of movie titles, the year it was made and the omdbID. I am try to take the omdbID value from the result and place that into a button that will call another method (which does a different API call to OMDB) to provide the rating of that specific movie that the user selected. At the moment I am unable to get the button to provide any action, even though I believe I have my route configured correctly. Below is a part of my view. The results show correctly, and I get a button next to each result. But the button does nothing. <% @responsealltitles.each do |result| %> <td><%= result["Title"] %> </td> <td><%= result["Year"] %></td> <td><%= result["imdbID"] %></td> <td><%= submit_tag("Search for Rating") %> <%= label_tag(:find_rating, "Show Movie Rating") %> <%= form_tag( "findrating", method: "post") do %></td>
Here is my routes entry match 'findrating', to: 'info#inforated', via: [:get, :post]
Any thoughts what is wrong here? I am a beginner at coding, and at ruby. |

| Ruby modulus. Why are these two sums printing different answers? Posted: 12 Nov 2016 05:57 AM PST I'm learning ruby and having problems with the %Modulus sums. puts "example #{101 % 4}"

I understand that % is just another way of saying 'X divided by Y with J remaining". Therefore surely the 2nd example should also return 1? Any help will be greatly appreciated. |

| Posting on Facebook page using Koala with automatic renewal of auth code Posted: 12 Nov 2016 02:47 AM PST I am using Rails 4 and have a working system to post on three different Facebook-PAGES using Koala. The only problem is that I have the Koala API auth codes hard coded into initializers and I need to renew them every 60 days (sometimes earlier). I have read, and re-read, every SO-question as well as the documentation but get none the wiser. I do NOT have any users logging into the website through Facebook or anything like that. This is all handled as a rake, posting excerpts of my blog posts on my Facebook-page. I have the following information (all tokens, ID's etc are examples): - My application ID: my_app_id #=> 12343423423749274734 - My application secret: my_app_secret #=> fc2323cdf2ce2312cdc121efed212 - Page id for first Facebook Page (of three): fb_page1_id #=> 343395105021155
With this I can create a Koala-Oauth connection: oauth = Koala::Facebook::OAuth.new(my_app_id, my_app_secret, "http://www.mywebsite.com")
by which I can get an app_access_token: oauth.get_app_access_token #=> 1231231726347364273|VhfeSDf43JdsdfJsERFE
This is, however, a dead end to me. I can't use this for anything. If I go to https://developers.facebook.com/tools/explorer I can get an access token for my application that looks something like this: tmp_token = "EAADaSDASDAMZBoBEBADBDuAqvgUYJPe7sJ5qmgoF3N1awXR4VTET3FYzXFZAPz0jLAoo8d4aaASd9BBZAp9aWbHB2xEvjFbo5At8ekuwyhFDCKbP0m4OYWmbM9GjSfq2KibjASDASDGAAHZCLIVmjWf2JQwj0N0VWBytI2eiswZDZD"
by which I can create the rest: base_connection = Koala::Facebook::API.new(tmp_token) page_1_token = base_connection.get_page_access_token(fb_page1_id) page_1_api = Koala::Facebook::API.new(page_1_token) page_1_api.put_connections("me", "feed", message: "Test")
...which successfully posts "Test" to my Facebook Page. The problems I have now are: - I need to manually renew the
tmp_token in my initializer every 30-60 days, which is the problem I need to get away from. - I don't understand how to get from the
oauth.get_app_access_token to tmp_token. Basically, I can't create a tmp_token automatically in my rake-function. I realize it could have to do with using: oauth.url_for_oauth_code
to get the code variable as a GET and then use oauth.get_access_token(code)
Is this the right (only?) way to go? I tried the code I got in my adress field and input it into oauth.get_access_token(code) in my console but got an error: "Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request [HTTP 400]" when I did that. So, now I am very confused how to proceed. How can I either: - renew my tmp_token on a frequent basis so I don't end up with expired a token?
- OR, create a tmp_token in my rake-function?

| Self association in rails to keep track of related records Posted: 12 Nov 2016 02:04 AM PST I have a model named Letter and an other one named LetterTracking : class Letter < ApplicationRecord has_many :letter_trackings, as: :trackable end

as you can see in below screen shots when I select a tracking record for the second tracking the relation is ok but when ever I add the third letter tracking the second one relation removes and the last one keeps the association. What I want is to keep the letter tracking in each record not by the last one. I mean some thing like nested records in which I can keep the related records. any Idea ? Thank you   |

| Rails - LoadError (Expected xxx/controllers/application_controller.rb to define ApplicationController) Posted: 12 Nov 2016 01:31 AM PST I build a backend service (nginx + passenger + rails) on AWS. My service is running as expected most of the time but sometimes goes wrong when passenger creates a weird new process to handle request: [INFO] Started POST "/apixxxxxx" [FATAL] LoadError (Expected /xxxxxxxx/app/controllers/application_controller.rb to define ApplicationController): [INFO] Started POST "/apixxxxxx" [FATAL] ActionController::RoutingError (uninitialized constant ApplicationController): [INFO] Started POST "/apioooooo" [FATAL] ActionController::RoutingError (uninitialized constant ApplicationController): ...
It has some signature on this weird process: - Other ruby process still works fine when this specific weird ruby process keeps failing on every new request.
- If error happens, it always starts by the "LoadError" in the beginning of the process's first request.
- This kind of "uninitialized constant" error keeps forever as long as this process is alive.
Here is some information of my machine: - ec2 type : m4.large
- storage : general purpose SSD (use EBS)
- system : ubuntu 14.04.2 (not AWS version)
- application : version 1.8.1, passenger 5.0.26, Rails 3.2.22.2, ruby 2.2.4p230, sidekiq 4.1.1
I also googled some keyword like "AWS EBS volume's IOPS limit" or "sidekiq thread" with this LoadError issue but no luck. Is there any new direction to investigate this problem? |

| Error - 11750 TwiML response body too large Posted: 11 Nov 2016 10:11 PM PST Hi i have integrated twilio in application. In twilio every thing is working fine for me. But once the call ended am getting Error - 11750 TwiML response body too large. Here what i have did from my end. def connect twiml1 = Twilio::TwiML::Response.new do |r| r.Say "You have joined the conference." r.Dial do |d| d.Conference "#{conference_title} #{call.id}", waitUrl: " ", muted: "false", startConferenceOnEnter: "true", endConferenceOnExit: "true", maxParticipants: 5 end end render xml: twiml1.to_xml end
Once the conference ended am doing some payment related to application requirement. def call_status if params["CallStatus"] == "completed" request_call = RequestCall.find { |c| c.caller_sids.include?(params["CallSid"])} if request_call.present? #save call logs call_log = CallLog.new(called: params[:Called], tostate: params[:CallerCountry], callercountry: params[:CallerCountry], callerzip: params[:CallerZip], direction: params[:Direction], timestamp: params[:Timestamp], callbacksource: params[:CallbackSource], callerstate: params[:CallerState], tozip: params[:ToZip], sequencenumber: params[:SequenceNumber], callsid: params[:CallSid], to: params[:To], calledzip: params[:CalledZip], calledcity: params[:CalledCity], tocountry: params[:ToCountry], apiversion: params[:ApiVersion], callstatus: params[:CallStatus], duration: params[:Duration], from: params[:From], callduration: params[:CallDuration], accountsid: params[:AccountSid], calledcountry: params[:CalledCountry], callercity: params[:CallerCity], caller: params[:Caller], fromcountry: params[:FromCountry], tocity: params[:ToCity], fromcity: params[:FromCity], calledstate: params[:CalledState], fromzip: params[:FromZip], fromstate: [:FromState], user_id: request_call.user_id, expert_id: request_call.expert_id, request_call_id: request_call.id) call_log.save #check caller length if request_call.call_ended == false && request_call.call_id_length == true # Check estimate time with total duration if request_call.estimated_time.to_i == call_log.duration.to_i release_payment = request_call.release_full_payment elsif request_call.estimated_time.to_i < call_log.duration.to_i make_payment = request_call.release_full_payment express_item_id = request_call.express_item_id extra_time = call_log.duration.to_i - request_call.estimated_time.to_i pending_amount = request_call.price_to_pay(extra_time) second_item = request_call.express_item(pending_amount) if second_item.code == 200 express_payment = request_call.release_express_payment end render json: {status: true} elsif request_call.estimated_time.to_i > call_log.duration.to_i remaining_duration = request_call.estimated_time.to_i - call_log.duration.to_i refund_amount = request_call.price_to_pay(remaining_duration) refund = request_call.refund_partial_amount(refund_amount) release_fund = request_call.release_full_payment render json: {status: true} end request_call.transition_to!(:completed) request_call.update(twilio_allocated_number: nil, twilio_access_code: nil, call_ended: true) elsif request_call.call_ended == true && request_call.call_id_length == true render json: {status: true} elsif request_call.call_ended == false && request_call.call_id_length == false #make payment request_call.transition_to!(:completed) request_call.update(twilio_allocated_number: nil, twilio_access_code: nil, call_ended: true, single_user: true) render json: {status: true} end else render json: {status: false} end else render json: {status: false} end

| Rails has_many index column can't be null Posted: 11 Nov 2016 10:34 PM PST I am making a Message model, the association is User has_many messages Message belongs_to user
There are two kind of messages, one is public and the other is private. It depends on its is_public column. Here is my message schema create_table "messages", force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8" do |t| t.string "title" t.text "content", limit: 65535 t.boolean "is_public" t.integer "user_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.index ["user_id"], name: "index_messages_on_user_id", using: :btree end
I think only private message should contain user_id. However, I found out that I can't create message directly. For example m = Message.create => #<Message:0x007fa6724e9d80 id: nil, title: nil, content: nil, is_public: nil, user_id: nil, created_at: nil, updated_at: nil> Message.count => 0 User.first.messages << m Message.count => 1
Is there a better way I can keep the index and create message without associating? |
| JQuery can't find the Sub Category ID Posted: 11 Nov 2016 10:57 PM PST I followed the instructions in this question's answer by emmanuel and the form now finds the Category ID and submits it but does not find the Sub Category ID associated with the Category and does not save it. The params are taken which can be noted by this, Parameters: {"utf8"=>"✓", "authenticity_token"=>"PTRTGGblf3HoWNXmanKl8TIP7F4j/QKTLN2Wd6oKSQWSXV27qioztUpXgb6YjHEroaWf8dgTzUIgQiRBK2XxWQ==", "post"=>{"title"=>"200k", "description"=>"FMxd123", "category_id"=>"2", "subcategory_id"=>"9"}, "commit"=>"Create Post"} It then shows the error message on my screen (with my error partial) that "Sub Category must exist. The SQL output is like so: (0.2ms) begin transaction Category Load (0.1ms) SELECT "categories".* FROM "categories" WHERE "categories"."id" = ? LIMIT ? [["id", 2], ["LIMIT", 1]] (0.0ms) rollback transaction Rendering posts/new.html.erb within layouts/application Rendered shared/_errors.html.erb (0.8ms) Category Load (0.1ms) SELECT "categories".* FROM "categories" CACHE (0.0ms) SELECT "categories".* FROM "categories" SubCategory Load (0.1ms) SELECT "sub_categories".* FROM "sub_categories" WHERE "sub_categories"."category_id" = ?

[["category_id", 2]] SubCategory Load (0.1ms) SELECT "sub_categories".* FROM "sub_categories" WHERE "sub_categories"."category_id" = ? [["category_id", 3]]
My Posts.coffee: jQuery -> subcat = $('#subcategory-select').html() $('#category-select').change -> cat = jQuery('#category-select').children('option').filter(':selected').text() options = $(subcat).filter("optgroup[label='#{cat}']").html() if options $('#subcategory-select').html(options) else $('#subcategory-select').empty()
And the part where category_id and sub_category_id are taken in the form with select boxes: <p> <%= f.label :category_id%> <%= f.collection_select(:category_id, Category.all, :id, :name, { prompt: 'Select a category' }, { id: 'category-select' }) %> </p> <p> <%= f.label :subcategory_id%> <%= f.grouped_collection_select :subcategory_id, Category.all, :sub_categories, :name, :id, :name, { include_blank: 'Select a sub category' }, { id: 'subcategory-select' } %> </p>
Confused as to how it isn't working because it made my category_id get saved when it wasn't working. Any ideas? |

| How to fix drop table migration rollback with empty down method Posted: 11 Nov 2016 10:45 PM PST I made a mistake at work by running rake db:migratewith bunch of migrations. I ran rake db:rollback to roll those back to previous state. One of the migrations had drop table in the "up" method. The same migration's "down" method was empty. Now rails keeps complaining that this table does not exist in mysql, and it will not start. I see in schema.rb this table is not present anymore. Just to be thorough we have two app servers, and 2 rails admin servers running this code. This issue is happening on rails_admin servers only.
Is there a way to fix this error. EDIT: These tables are not needed anymore, so don't care about the data. I just want to be able to start my app without seeing the error "mysql2::error: table "xyz" doesn't exit |
| Why does my content_tag not produce the HTML I expect? Posted: 11 Nov 2016 06:57 PM PST I am rendering my Profiles#Index view. In that view, I call this helper method: <%= ratings_labels(profile, params[:rating]) %>
That is defined in profiles_helper.rb, like so: def ratings_labels(profile, rating_param) rating_classes = { 'speed' => 'label label-success label-lg', 'tackling' => 'label label-info label-lg', 'passing' => 'label label-warning label-lg', 'dribbling' => 'label label-primary label-lg' } rating_classes.each do |rating, klass| content_tag :div, class: "col-lg-3" do content_tag :span, class: "#{klass}" do "#{rating.capitalize}: #{profile.ratings.find_by(user: current_user)[rating]}" end end end end end
However, what the outputs in my HTML is this: {"speed"=>"label label-success label-lg", "tackling"=>"label label-info label-lg", "passing"=>"label label-warning label-lg", "dribbling"=>"label label-primary label-lg"}
Notice there is no HTML generated. No div.col-lg-3 or span. Why is that? |
