| Save my table historic with all the authorizations ids checked Posted: 25 Apr 2016 07:01 AM PDT I have a problem... I need save my table historic with all the authorizations ids checked, update the column authorization_origin_id and set the column refinancing_id with the refinancing id created. Example: I checked authorizations ids 2 and 3, so I create historic with two lines with authorization_origin_id 2 and 3 and the refinancing id will be 1. My code: def new if params[:authorization].present? @selected_ids = params[:authorization][:contract_number] @authorizations = Authorization.where("contract_number in (?)", @selected_ids) auth_params = params[:authorization] auth_params[:contract_number].zip(auth_params[:value_solve].reject(&:blank?)).each do |contract_number, value_solve| Authorization.where(contract_number: contract_number).update_all(value_solve: value_solve, situation: 2) end @authorizations.ids.each do |auth_id| @historic_refinancing = HistoricRefinancing.create @historic_refinancing = HistoricRefinancing.update_all(authorization_origin_id: auth_id) end end @employee = Employee.search_cpf(params[:search_employee_by_cpf]) @refinancing = Refinancing.new end
My view: <%= simple_form_for(@refinancing) do |f| %> <div class="form-inputs"> <%= f.hidden_field :employee_id, value: @employee.first.id %> <%= f.hidden_field :authorization, value: @authorization %> <%= f.input :contract_number %> </div> <h3>Reserved value</h3> <table class="table table-condensed table-bordered table-striped"> <thead> <th>Authorization id</th> <th>Contract number</th> </thead> <% @authorizations.each do |authorization| %> <tbody> <tr> <td><%= authorization.id %></td> <td><%= authorization.contract_number %></td> </tr> </tbody> <% end %> </table> <div class="form-actions"> <%= f.button :submit, "To Reserve" %> </div> <% end %>
Actually my table historic is wrong, authorization_origin_id take, just the last (just one ever =/) value checked and refinancing_id is null |

| Restrict Access to a Rails WebApp Posted: 25 Apr 2016 06:58 AM PDT I'm currently building an app. for my office to use however we don't want anyone outside of our office's network to be able to access it. Because we are a part of a larger network I can't be sure that IP addresses won't randomly change. Is there any way to better restrict access by something that won't randomly change than by IP address? I was thinking of keeping the application running on a local server that everyone could access but then that opens the door to other issues and is no longer an option. Any tips would be greatly appreciated! Thanks. |

| rails5 api + devise_token_auth: no access-token and uid returns after login successfully via omniauth2 Posted: 25 Apr 2016 06:24 AM PDT I am using devise_token_auth for omniauth2 login with weibo and qq. Yes, I am trying to use rails5 api feature! After setup and using omniauth test_mode, I seems like login successfully but not login info(access_token, expiry, client and uid) return in the header of response. Here is model, I apply candidate rather than user as authentication resource. #app/models/candidate.rb class Candidate < ApplicationRecord devise :database_authenticatable, :trackable, :omniauthable include DeviseTokenAuth::Concerns::User has_many :recruitments attr_writer :password, :password_confirmation end
Using dummy omniauth successful info. #config/environment/development.rb #OmniAuth Fake OmniAuth.config.test_mode = true OmniAuth.config.mock_auth[:qq_connect] = OmniAuth::AuthHash.new( { provider: 'qq_connect', extra: { raw_info: { nickname: :dev } }, info: { nickname: :dev }, uid: '123456' }) OmniAuth.config.mock_auth[:weibo] = OmniAuth::AuthHash.new( { provider: 'weibo', extra: { raw_info: { nickname: :dev } }, info: { nickname: :dev }, uid: '1234567' })
So, when I send a get request to http://localhost:3000/auth/weibo, application redirect me to http://localhost:3000//auth/weibo/callback. It returns 200 Ok. As far, everything seems fine. And also I check DB, which shows that candidate(authentication resource) was created, and its token changed with every request to it. But look at the header of response, I find nothing useful(access-token, expiry etc) inside. #Header of response Cache-Control →max-age=0, private, must-revalidate Connection →close Content-Type →text/plain; charset=utf-8 ETag →W/"7215ee9c7d9dc229d2921a40e899ec5f" Server →thin 1.6.2 codename Doc Brown X-Content-Type-Options →nosniff X-Frame-Options →SAMEORIGIN X-Request-Id →d91648bb-3e69-4d23-8dfa-9eedfafeac26 X-Runtime →0.085038 X-XSS-Protection →1; mode=block
So My question is How to get auth info(likes access-token, client etc) after login with omniauth2? Regards! |
| Can I create a Rails resource route called 'index'? Posted: 25 Apr 2016 06:16 AM PDT I want to add a resource route called index to an application but the generated routes aren't as expected. However, if I use another name (such as show_index), they are. To demonstrate, I'll begin with a vanilla Rails app that has no routes: $ rake routes You don't have any routes defined!
I add the below into config/routes.rb: resources :items
Which produces the usual resourceful Rails routes: Prefix Verb URI Pattern Controller#Action item_index GET /item(.:format) item#index POST /item(.:format) item#create new_item GET /item/new(.:format) item#new edit_item GET /item/:id/edit(.:format) item#edit item GET /item/:id(.:format) item#show PATCH /item/:id(.:format) item#update PUT /item/:id(.:format) item#update DELETE /item/:id(.:format) item#destroy
I want to add a custom index route that invokes the show action with an added parameter. I change the route definition to: resources :item do member do get 'index' => 'items#show', with: 'index' end end
Giving this diff of the routes: > item GET /item/:id/index(.:format) items#show {:with=>"index"} < item GET /item/:id(.:format) item#show --- > GET /item/:id(.:format) item#show
Rather than just adding one route, it alters one and adds a second, and neither have the expected method prefixes (which should have the form <route>_<resource>, i.e. index_item). However, if I use a different name: get 'show_index' => 'items#show', with: 'index'
then the diff is as I would expect - one new route with the expected method prefix: > show_index_item GET /item/:id/show_index(.:format) items#show {:with=>"index"}
I expect there's a problem using index because the implied resources routes use that name, although I don't think they use it in a way that would clash. It looks to me like I should to be able to add a new index route which would become index_item (in contrast to the existing item_index). I know I can work around the problem, as I have demonstrated, by using a different name. But index reads better than show_index. So my question asks is there a way to add a route using the word index ? |
| Missing some rabbitMQ messages Posted: 25 Apr 2016 06:01 AM PDT I have strange issue, while broadcasting messages to clients. This is my code, that is responsible for publishing messages: AMQP.start(:host => property(:amqp_host), :vhost => property(:amqp_vhost), :user => property(:amqp_user), :pass => property(:amqp_pass)) do exchange = MQ::Exchange.new(MQ.new, :topic, "games" ) exchange.publish( @message, :key => @key ) AMQP.stop { EM.stop } end
I'm using old version of AMQP gem(rails 2.3.8). The problem is - When there is only one client, this client gets all messages, if there are more than 1 client, all messages gets last connected client. I've tried to publish to different keys, and split clients through pool of available keys, but still same. Is there something i've missed? |

| What does `status: :ok` do in `render json:` (Rails) Posted: 25 Apr 2016 06:01 AM PDT What doesstatus: :ok do in render json: {round: @round}, status: :ok? Sometimes everything works without it, but sometimes its necessary to prevent an error like, ActionController::UnknownFormat (ActionController::UnknownFormat):
I use Angular for front-end and Rails for back-end. My understanding is that this final line in the Rails controller action converts the server response back to json format so Angular can read it (not 100% confident this is correct explanation). But I don't understand why to use one or the other of the following. Sometimes one works and sometimes the other does. render json: {round: @round}, status: :ok1respond_to :json and respond_with @round Can anyone share some insight? |
| Memory vs Database difference in a variable value Posted: 25 Apr 2016 05:44 AM PDT I have a pdf attachment boolean flag set in my application and my database shows it to be set true.

| Rails Braintree webhook integration not working Posted: 25 Apr 2016 05:27 AM PDT i'm trying to implement Braintree's webhook capabilities into my rails app but with no success. I have followed every single step in their documentation - https://developers.braintreepayments.com/guides/webhooks/overview but it still doesn't work. Here's the code in my webhook controller: class BraintreeWebhookController < ApplicationController skip_before_filter :verify_authenticity_token require 'braintree' def webhook webhook_notification = Braintree::WebhookNotification.parse( bt_signature_param, bt_payload_param ) #operations here onwards #... render status: 200 end def get_webhook challenge = bt_challenge_param challenge_response = Braintree::WebhookNotification.verify(challenge) render plain: challenge_response, status: 200 end private def bt_signature_param return params[:bt_signature] end def bt_payload_param return params[:bt_payload] end def bt_challenge_param return params[:bt_challenge] end end
The webhook function is for the HTTP POST request while the get_webhook function is for HTTP GET request. I'm not actually sure what the coding in the get_webhook function does and it's not in Braintree's documentation but I found it in one of a user's sample application on Github. I have configured the routes as below: post 'braintree/webhook' => 'braintree_webhook#webhook' get 'braintree/webhook' => 'braintree_webhook#get_webhook'
Once i hit the 'Check URL' button in Braintree's webhook control panel, nothing happens except for the error message Last delivery unsuccessful. Invalid server response Any help would be very much appreciated and by the way, my site is SSL encrypted and uses HTTPS protocol, don't know if that affects the webhook operations or not. |
| Using rails_admin with rails_api Posted: 25 Apr 2016 05:13 AM PDT I originally posted this as an issue on rails_api GitHub, but am now posting it here due to inactivity. I'm trying to use rails_admin with a Rails 5 API application. I have this working up to the point that I can either have a functioning rails_admin panel or working API requests. The issue seems to be that rails_admin depends on ActionView::Layouts, which after included causes issues for API requests. Gemfile: gem 'rails', '>= 5.0.0.beta3', '< 5.1' ... gem 'rack-pjax', github: 'afcapel/rack-pjax' gem 'remotipart', github: 'mshibuya/remotipart' gem 'kaminari', github: 'amatsuda/kaminari', branch: '0-17-stable' gem 'rails_admin', github: 'sferik/rails_admin'
I configured my application to use ActionDispatch::Flash: module MyApp class Application < Rails::Application ... config.middleware.use ActionDispatch::Flash end end
I configured extra modules for Rails API, ApplicationController: class ApplicationController < ActionController::API include Knock::Authenticatable include Pundit # RailsAdmin support include AbstractController::Helpers include ActionController::Flash include ActionController::RequestForgeryProtection include ActionController::MimeResponds include ActionController::HttpAuthentication::Basic::ControllerMethods include ActionView::Layouts end
With these changes the Rails Admin dashboard seems to run fine. However, when I'm trying to access the JSON resources in my application, the following error is thrown: Error: BookingsControllerTest#test_should_get_index: ActionView::MissingTemplate: Missing template bookings/index, application/index with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :haml]}. Searched in: * "/Users/richard/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/bundler/gems/rails_admin-355dc80f8a20/app/views"
This is the controller code: class BookingsController < ApplicationController def index @bookings = find_bookings render json: @bookings, include: ['customer', 'client'], meta: meta end end
This only happens after I include the ActionView::Layouts module in the top level ActionController::API class to support Rails Admin. Have been trying things for a couple of hours now.. does anyone have a suggestion? |
| Rails: A user can create other users with different set of permissions Posted: 25 Apr 2016 05:46 AM PDT This might be a duplicate of a question already asked but i haven't found the one that suits my condition yet. I am developing a system where there's a user (not an admin) who is registering himself using devise. What i want is to allow this user to create different users and provide them different set of permissions (so can't be predefined permissions and hence, cant use cancan as far as i am aware). To clarify more, this is the table structure i have come up with yet. Please guide me if i am going on the wrong path here. USER: id, name, other-details
PERMISSION id, name, (name of the section such as gallery, report or users) create, edit, view, user_id (the user whose permissions are defined here)
Here, create, edit and view are the permissions that the user would have. If the edit is true, he'll be able to edit that particular section. I'm sorry if this is not clear. I found Johan's answer (last one) Database schema for ACL match my scenario however i am not sure if its the right way. Also, i am not sure how to implement the SET mentioned there. Thanx in advance. Also please feel free to ask for more details if required. I'm clueless about how right this method will be. P.S: Newbie in Rails Here. |

| Rails 4 - datetimepicker-rails gem, datepicker not disabling Posted: 25 Apr 2016 03:57 AM PDT I am using the datetimepicker-rails gem (https://github.com/zpaulovics/datetimepicker-rails) I would like to have a simple timepicker, but datepicker is always present. I tried with using the "format" option, the "pickDate: false" option but it is still there. What am I doing wrong? Here is the sample of my view: <%= simple_form_for(@hour, html: {class: 'form-inline'}, remote: true) do |f| %> <%= f.error_notification %> <div class="row form-inputs"> <%= f.input :start_time, as: :time_picker, autocomplete: :off %> <%= f.input :end_time, as: :time_picker, autocomplete: :off %> </div> <div class="form-buttons"> <%= f.button :submit, "Zapisz", class: "btn btn-primary" %> <%= link_to '<button type="button" class="btn btn-primary" title="Wstecz">Wstecz</button>'.html_safe, hours_path %> </div> <% end %>
and in coffee script I have $(document).ready -> $('.time_picker').datetimepicker XXX
where XXX was one of the options I tried: format: "H:i", format: "LT" or pickDate:false. Thank you in advance for your help. Regards, Paulina |
