Custom Controller Method, Route, & ERB Posted: 04 Dec 2016 07:52 AM PST I have a search form and I need to be able to filter based on whether or not pets are allowed, but I'm not sure how to accomplish this. I have setup a route, a controller method, and a button but none of that seems to be working. listings_controller: def pets_allowed @listings = @listings.where(pets: true) end routes.rb: get "pets_allowed" => "listings#pets_allowed" html.erb file: <div> <%= link_to 'Pets Allowed', pets_allowed_path, :class => 'button btn-transparent' %> </div>

Rails 5 - how to dynamically add nested fields in the edit form? Posted: 04 Dec 2016 07:48 AM PST Already a month trying to solve the problem at first sight is not very complicated: There are 3 models - team, user and team_user (has_namy: through) In the form of edit and new team to do the ability to dynamically add members of this team. Scenario: - A user comes to the team new form - Indicates the name of the team - After name field select user (team member) - Click the Add member button - After validation of a member is added after team's name field in text field + delete button opposite - From the selector delete his (member) name (as it is already a team member) - In selite selects the next user, and click the Add member button - Press the Submit button to save the new team and team's members Difficulties: - I tried to do through the gem Cocoon, but it is impossible to make different parshaly to select the user to be added to it (SELECT) and has added members (full name - text) - If done through the <% = from_for ... remote: true%> and a separate controller or new action in the controller teams_controller, it will be two forms of nested (shape and form team team_user) with his 2nd submit button. Attachment forms, as I understand, is not gud. - Changes in the form (changing the name of the team and add / remove the team members have the count only after clicking on the save to basically submit the form team)

Faraday::ConnectionFailed after resetting my cable modem Posted: 04 Dec 2016 07:49 AM PST I have (or had) omniauth-google-oauth2 successfully working in my rails app until this morning. My internet provider was briefly down and I also reset my cable modem. Now I get the following error after attempting to secure permission from google: Faraday::ConnectionFailed execution expired 878 s = Timeout.timeout(@open_timeout, Net::OpenTimeout) { 879 begin 880 TCPSocket.open(conn_address, conn_port, @local_host, @local_port) 881 rescue => e 882 raise e, "Failed to open TCP connection to " + 883 "#{conn_address}:#{conn_port} (#{e.message})" And Line 880 is highlighted in the message. Any ideas?

Unable to redirect from user edit page using devise gem Posted: 04 Dec 2016 07:30 AM PST I am using devise gem version 4.1.1 in my rails project and in my /users/edit page I want to redirect to the same page after the user changes his password instead of redirecting to the root_path. I googled around and found this link devise github wiki I did make the changes accordingly and my registrations controller is as follows class RegistrationsController < Devise::RegistrationsController protected def after_update_path_for(resource) edit_user_registration_path end end and in routes.rb I added the registrations controller devise_for :users, controllers: { confirmations: "confirmations", registrations: "registrations"} But still for some reason I am not able to redirect to the same page and it still redirects to root_path. Am I missing something?

Rails: why emails are sent before Users submit the form? Posted: 04 Dec 2016 07:24 AM PST I have a "Static form" that sends pricelists to clients, I need to send an email but params[:pricelist_name] from the form is nil. I noticed that emails are sent before the view, so I was wondering how to send emails only after that users submit the form ? Cheers, Controller def sendpricelist @pricelist = params[:pricelist_name] || [] @request_id = params["pricelist_name"] || [] @test = "test" SaasMailer.pricelist_request_email(@pricelist, @test, @request_id).deliver_now #redirect_to :requests end View <%= form_tag(:controller => "requests", :action => "sendpricelist") do %> <%= text_field(:post, :title, size: 69, class: 'form-control form-group-lg') %> <%= select_tag 'pricelist_name', options_from_collection_for_select(Pricelist.all, :id, :name) %> <%= submit_tag("Send pricelist")%> <% end %> Routes devise_for :users resources :users resources :requests do resources :updates match '/sendpricelist', to: 'requests#sendpricelist', via: 'get' end Output: As you can see in 'Subject: [] - [] - test' params are nil.

Rails 5 starting thread from initializer gone crazy Posted: 04 Dec 2016 06:31 AM PST I have the following code in config/application.rb: config.after_initialize do MyConcern.init_processing end Then the following related methods: def init_processing @queue_processor = Thread.new do process_op_queue end @queue_processor.name = "Some Queue" # @queue_processor_notifier = Queue.new end def process_op_queue while true req = MyRequest.where(done: Helper::FALSE_NIL_OR_MISSING, started_at: nil).order_by(id: :asc).find_one_and_update({'$currentDate' => {started_at: true}}, return_document: :after) req ? process_queue_item(req) : sleep(30) end end Basically starting a thread on server startup to perform some background tasks that are accepted by the app from users by HTTP calls. In development mode everything works fine. Running in production env with same puma server, the @queue_processor shows dead (from rails console): MyConcern.instance_variable_get("@queue_processor").join => #<Thread:0x00000002b8fa68@MyConcern Queue@/var/lib/openshift/5842d71a5110e25cdf00000c/app-root/runtime/repo/app/controllers/concerns/my_concern.rb:23 dead> MyConcern.instance_variable_get("@queue_processor").value => false First it is (mildly said) non-obvious to me how a thread can die without an exception and returning false with the loop that I have above in process_op_queue. The other very interesting facts are that: there is actually a thread doing the work as obvious to me while doing requests to the app and looking at what changes in the database in rails console I see only one thread: . 2.3.1 :009 > Thread.list => [#<Thread:0x000000012f63a8 run>] 2.3.1 :010 > Part of the app is checking the queue processor thread and reporting errors with it so showing up as dead is really breaking that logic. Any advises how to debug and resolve the issue would be appreciated. Thank you.

Getting data from many to many relation with rails 4 Posted: 04 Dec 2016 07:07 AM PST I am developing a rails app with mysql database. Theres bunch of tables but for this task I am using only 3. Students, Courses and CoursesPerStudent. I have models for students and courses(no model for the third). The tables are already populated. The tables: students - id,name,family,address,phone,email,status,path courses - courseCode, courseName, hours coursesperstudent - code, student(same ids as in students table ids but not a oreign key),path,course(courses table code(foreign key)),examMark. Now the thing is i need to show for each student a list of the courses realted to him. How should i do it? Should i create model for the third table? how should i call it? and combine the two other tables in one to show specific courses? Or there some other way? Hopefully someone will help because im out of answers.

Finding free appointment slots from appointment table Postgresql Rails Posted: 04 Dec 2016 04:07 AM PST I have an app in ruby on rails that has Appointments which belong to Providers and I am looking to create a query that finds a provider's gaps in appointments Appointments are stored as a start and finish both which are datetimes . Ideally I would call Provider.free_appointment_slots(length,start,finish) where length is the length of the appointment required and start and finish are bounds of the search ie a particular week or day. I think it should be somewhat similar to these... How to return all the free periods of time from an appointment set Finding free blocks of time in mysql and php? I have an appointments table with data like: ID | Start | Finish | ProviderID 1 2016-11-12 09:00 2016-11-12 09:30 1 1 2016-11-12 10:00 2016-11-12 10:30 1 1 2016-11-12 11:30 2016-11-12 12:00 1 etc I would like to be able to provide a start and end time to search over and an appointment length and my query return the available appointment times.. for example If I was looking for appointments between 2016-11-12 08:30 and 2016-11-12 12:30 with an appointment length of 30min I would receive results such as: Start | Finish 2016-11-12 08:30 2016-11-12 09:00 2016-11-12 09:30 2016-11-12 10:00 2016-11-12 10:30 2016-11-12 11:00 2016-11-12 11:00 2016-11-12 11:30 2016-11-12 12:00 2016-11-12 12:30 an additional great feature would be to be able to provide multiple search periods such as over different days I hope this is clear any help would be much appreciated

Having trouble in updating join model extra attributes in has_many through association - Rails Posted: 04 Dec 2016 05:51 AM PST I am still a learner of Rails, and am making a simulation game of Google Adwords for training usage. Inside the game (I may only explain the related part of this question), I have three models, Adgroup (called KeywordAdgroup in my code), Keyword, AdgroupKeyword, and also a Game model that has a game_id in it. The relationship of the three models is a has_many through: assciation, which Adgroup has many Keywords through AdgroupKeyword, and Keyword has many Adgroups through AdgroupKeyword. Now, I want to adopt a logic that every Keyword could only be added into single Adgroup of a particular game. So I added an extra attribute game_id to the join model - AdgroupKeyword, and adopt validates_uniqueness_of :keyword_id, scope: :game_id into this model. However, I found that with the similar code, I can validate the uniqueness in Create using .save method, but I can't validate the uniqueness in Update using .update(params) method. The major problem is that, with the similar code in create and update, the create one can save the game_id to the join model(AdgroupKeyword), where update(params) didn't save the game_id to the join model, which in the console, I can see that update didn't insert game_id into the record. It will become something like game_id: nil: #<AdgroupKeyword id: 180, keyword_id: 9, created_at: "2016-12-04 11:12:00", updated_at: "2016-12-04 11:12:00", keyword_adgroup_id: 77, game_id: nil> But the save method did insert the game_id, which game_id is not nil when inserted using the save method. Something like #<AdgroupKeyword id: 174, keyword_id: 10, created_at: "2016-12-04 10:23:50", updated_at: "2016-12-04 10:23:50", keyword_adgroup_id: 77, game_id: 3> The following is my code: keyword_adgroup.rb (the model of Adgroup) class KeywordAdgroup < ApplicationRecord belongs_to :keyword_campaign has_many :adgroup_keywords, inverse_of: :keyword_adgroup, dependent: :destroy has_many :keywords, through: :adgroup_keywords, source: :keyword accepts_nested_attributes_for :adgroup_keywords, allow_destroy: true ... accepts_nested_attributes_for :keywords ... ... end keyword.rb class Keyword < ApplicationRecord ... ... has_many :keyword_adgroups, through: :adgroup_keywords has_many :adgroup_keywords ... end adgroup_keyword.rb(the join model) class AdgroupKeyword < ApplicationRecord belongs_to :keyword_adgroup belongs_to :keyword validates_uniqueness_of :keyword_id, scope: :game_id end And majorly the relation would be built in the Adgroup controller. adgroups_controller.rb class Adwords::AdgroupsController < AdwordsController def index ... end def new @adgroup = KeywordAdgroup.new end def create @campaign = current_user.game.keyword_campaigns.find(params[:keyword_campaign_id]) @adgroup = @campaign.keyword_adgroups.build(adgroup_params) @adgroup.game_id = @campaign.game_id @adgroup.adgroup_keywords.each do |join| join.game_id = @adgroup.game_id end if @adgroup.save redirect_to new_adwords_ad_path(keyword_adgroup_id: @adgroup.id) else render :new end end def edit @adgroup = KeywordAdgroup.find(params[:id]) end def update @adgroup = KeywordAdgroup.find(params[:id]) @campaign = @adgroup.keyword_campaign @adgroup.game_id = @campaign.game_id @joins = @adgroup.adgroup_keywords @joins.each do |join| join.game_id = @adgroup.game_id end if @adgroup.update(adgroup_params) redirect_to adwords_adgroups_path, notice: "Adgroup updated" else render :edit end end ... private def adgroup_params params.require(:keyword_adgroup).permit(:name, :activate, :bid, keyword_ids: [], adgroup_keywords_attributes: [:game_id]) end end When choosing duplicate keyword in the same game in whatever adgroup, in "create", it will come to a rollback; in "update", it will just update the record with game_id: nil. FYI, I am using Ruby 2.3.0, Rails 5.0.0, and using simpleform for creating and updating adgroup. I know its a little bit messy, sorry about that and thanks for reading my words. Appreciate any suggestions. Have already spent several hours to fix it but really hopeless after a lot of different methods. Thought that it was some conceptual problem that I haven't figured out.

Background image in inline CSS code doesn't show when ran in rails server Posted: 04 Dec 2016 05:47 AM PST I am editing my landing page for my web. I am currently using Rails 5 to develop my web. I have this css block here (I am using bootstrap as well): <div class="item"> <!-- Set the second background image using inline CSS below. --> <div class="fill" style="background-image:url('images/1.png');"></div> <div class="carousel-caption"> <h1 class="light mab-none">This is <strong class="bold-text">art</strong></h1> <h1 class="light margin-bottom-medium mat-none">And We Are <strong class="bold-text">Awesome</strong></h1> <p class="light margin-bottom-medium">Stop blending in & start leaving your mark on the web.</p> <div class="call-button"> <div class="row"> <div class="col-md-4 col-md-offset-2 col-sm-4 col-sm-offset-2 col-xs-12"> <a href="#portfolio" class="button pull-right internal-link bold-text light hvr-grow" data-rel="#portfolio">Our Work</a> </div> <div class="col-md-4 col-sm-4 col-xs-12"> <a href="#about-us" class="button pull-left internal-link bold-text main-bg hvr-grow" data-rel="#about-us">About Us</a> </div> <div class="clearfix"></div> </div> </div> </div> <div class="overlay"></div> </div> However, when I start my rails server, only the texts appear and the background image don't.

As for my images, they are all inside the images folder under assets.

Adding superuser to GitLab on Debian Jessie repository installation Posted: 04 Dec 2016 03:36 AM PST I've installed GitLab via debian jessie-backports and it installed fine but there was no prompt to create superuser account. I tried to add it manually, but every solution on the Internet use gitlab-rails which seems to be absent in my system. Is there any way to add superuser without relying on gitlab-rails tool?

Updating unique constraint index after deleting records Posted: 04 Dec 2016 03:19 AM PST So I've got a postgres database full of users create_table :users do |t| t.string :subdomain t.index [:subdomain], name: "index_users_on_subdomain", unique: true, using: :btree end One of them deletes their account by mistake and wants to sign up again. But a validation error is called. Even though the record itself was deleted, the subdomain still exists in the index duplicate key value violates unique constraint "index_users_on_subdomain" This feels like a bug to me. Shouldn't the index be updated in the after_destroy callback? Am I expected to manually drop and add the index each time someone removes their account? Any ideas?

React Native and Rails [on hold] Posted: 04 Dec 2016 02:17 AM PST I would like to write in first case a wep app. I am working since almost 2 years now with Rails and I like it very much. My views are always done by myself, which worked so far very good. Now I would like to expand my horizon. I want to differentiate frontend and backend. Why? Because my web app should me available as native app on iOS and Android too. So I thought I will use: http://edgeguides.rubyonrails.org/api_app.html as my backend. So everything responded as JSON. For building user interfaces and the web view I though React from Facebook would good. Because as soon as I decide to write an app I could use React Native for this purpose. So What do you think about this combination? Is this worth a try?

How to use jekyll on an existing blog made with rails Posted: 04 Dec 2016 02:33 AM PST My situation is that I have just finished creating a blog using ruby on rails. I have been using localhost to see it display on my browser, but I want to deploy it online. I found out that rails apps can't be deployed on ghpages because it is not static. However, I searched online and read that if I used Jekyll, i could display it on ghpages. I have never used jekyll before, so my question is... How could I use/integrate jekyll to my existing rails app so that it can be deployed and hosted through github pages? Thank you!

AngularJS $resource save success function not getting data Posted: 03 Dec 2016 11:56 PM PST I am building an application with Rails 5.0.0 with my back-end (api-only mode) and AngularJS as front-end. While testing on my localhost API in POSTMAN, I hit the POST endpoint - http://localhost:3000/sessions.json?session[email]=shahravi@gmail.com&session[password]=foobar and receive - { "id": 1, "name": "Ravi Shah", "email": "shahravi@gmail.com" } with status 200 from rails server - "Completed 200 OK in 120ms" I am using Active Model Serializer to get this response back through - render json: user, status: :ok inside my rails controller. However, inside my front-end angular code, when I hit the same endpoint, the $resource $save function does not execute the success callback. It gets the following data back from the endpoint in the error callback - {"data":null,"status":-1,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"data":{"session":{"email":"shahravi@gmail.com","password":"foobar"}},"url":"http://localhost:3000/sessions.json","headers":{"Accept":"application/json, text/plain, */*","Content-Type":"application/json;charset=utf-8"}},"statusText":""} My angular code is written as - sessionResource = new LoginResource({session: {email: $scope.email, password:$scope.password}}); sessionResource.$save(function(success){ console.log("Login success" + JSON.stringify(success)); $state.transitionTo('dashboard'); return true; }, function(error){ console.log("Login error - " + JSON.stringify(error)); }); where LoginResource is defined as - angular.module('SampleApp').factory('LoginResource', function($resource){ return $resource('http://localhost:3000/sessions/:id.json', {id: '@id'}, {'update': {method:'PUT'}}); }); Can somebody help figure out where the problem is? Why does rails server return success with right data, but angular does not get success code or the data?

How to disable sending default emails when a user place an order? Posted: 03 Dec 2016 11:46 PM PST I am working on a Third party application where I want to send customized template emails to user using webhooks when user place order or shipment gets created. Is it possible to prohibit system to send email to user who place order and instead of that just fire an event to a third party app(using a webhook) so that that third party app will send email to that user with required and customized new details in new email template(which is not available in default variables of email templates)? Any solution for this? Please

advance table search in rails Posted: 04 Dec 2016 12:54 AM PST In my app i have generated a scaffold called data and had filed the table with name, school, college, views, interest. Now i want to add a search that if someone put NAME in the search bar, they should get all the names only as results, if someone had put college, they should get all the college only.

Integrating Paypal button with Rails Posted: 03 Dec 2016 05:53 PM PST I am trying to integrate Paypal in my rails application by generating a hosted button from paypal. I am following the following guide https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/buy_now_step_1/ but I cannot find a way to dynamically generate a buy now button with custom prices and description without first creating it through paypal.com. My question is is there a way to generate the buttons dynamically from my database of items so that they don't have to be first created through paypal.com manually. or Is there a better way to do this? I'm new to both rails and paypal API.

ActiveRecord has_many where child model is greater than 0 Posted: 04 Dec 2016 01:46 AM PST I'm trying to solve a seemingly simple AR problem I'm having. I can't figure out how to return a list of events that have 1 or more attendees, and the docs examples use cache_control which I don't want to use. I have a simple event model with a has_many relationship: class Event < ActiveRecord::Base has_many :attendees end and an attendees model that belongs to event class Attendees < ActiveRecord::Base belongs_to :event end But some events will have 0 attendees. So what's the ActiveRecord way of doing this without using cache_control or writing a custom SQL statement? It seems like it would be something like: Event.where(attendees.count > 0) but I keep getting a column error.

How to manage slightly different versions of the same application on Ruby on Rails? Posted: 03 Dec 2016 10:22 PM PST I have a Rails 4.2 application that is tailor-made for a specific industry and now I have to upload the same app, but for a new client from a different industry. Given this, I need to do some slightly changes in the database and code (90% of the code should remain the same). What is the best approach to have different versions of the same app? Should I use Rails plugins? I don't want to have two completely separate application because I will be doing maintenance twice almost all the time and having one big app will make it too complicated (and also I need two different database structures) Please let me know what is the best option. Thanks!
