| How do I avoid "preflight requests"? Posted: 17 Apr 2016 07:13 AM PDT I am trying to get started with Ember Data and immediately ran into this problem were the browser sends a OPTIONS request before the actual request. The development backend I am trying to communicate with is a rails 4.2 server running on my local machine (started with rails s -b 0.0.0.0 ) I currently use this api to communicate from both an android and an ios app. My end goal is to provide an Ember app in addition to the existing rails UI, but if I have to replace it and only have the Ember UI, that will be OK. I did some reading on CORS and I think at at least understand what it is trying to do. If I understand correctly, the browser sees the Ember app as having been served by a server other than the one that requests are being made to and because of this asks the server if this is OK. So my questions are: - Will I be able to deploy my ember app to the real server such that these CORS OPTIONS requests are not needed? (ie, I assume a rails app can deliver an Ember app to the browser and the browser will see the source of the script as being the same as the target of the request and not require the prefight requests)
- How do I get this to work in development? I see there is a --proxy option on the ember s --proxy, which seemed like it was supposed to be the solution for this, but I have not been able to get it to work
When I navigate to the server url I am trying to access http://localhost:3000/api/v1/users rails logs the following response: Started GET "/api/v1/users" for 127.0.0.1 at 2016-04-17 10:02:01 -0400
Based on this, I think I have my Ember adapter set up correctly: import JSONAdapter from 'ember-data/adapters/json-api'; export default JSONAdapter.extend({ host: 'http://127.0.0.1:3000', namespace: 'api/v1' });
Then I start the Ember server with this command: ember s --proxy http://127.0.0.1:3000
The rails server is receiving the following request: Started OPTIONS "/api/v1/users" for 127.0.0.1 at 2016-04-17 09:36:51 -0400
Which fails because I don't have a route for that (and don't think I want to either). |
| saml call back url with devise Posted: 17 Apr 2016 07:11 AM PDT I have to authenticate user either by saml or by database credentials depending on how user wishes to get authenticated . I am stuck with two problems
1)I am receiving the saml response to the call back back url. I am not sure how to integrate it with devise.
2)I am not sure how to authenticate the user either by database or by saml response dynamically based on user choice. Any suggestion would be really helpful |
| Date works in development but not production Rails MongoDB Posted: 17 Apr 2016 07:10 AM PDT I have a Coupon class and I want my app to check and see how many counts are left on the coupon and if the date for the coupon has expired. I have the following method in my class to check both of these. Coupon class def self.get(code) where( :code => (normalize_code(code)), :$and => [ { :$or => [ { :coupon_count.gte => 1 }, { :coupon_count => nil } ] }, { :$or => [ { :expires_at.gt => Time.now.utc }, { :expires_at => nil } ] } ] ).first end
This works fine in development when I enter a coupon. But in production it does not work. I use my MongoDB shell to create a coupon as follows. db.Coupon.insert({code:'#COUPONNAME',discount_percent: 10, expires_at: new ISODate("2016-05-18"), coupon_count: 10, "description": '1st cold visit sign-up'})
It seems that the problem is when the Coupon checks the expires_at date. In development it finds the coupon and works but in production it keeps not finding the coupon. Just for good measure here is my controller method for this. charges_controller @code = params[:couponCode] if !@code.blank? @coupon = Coupon.get(@code) if @coupon.nil? flash[:error] = 'Coupon code is not valid or expired.' redirect_to new_managers_charge_path(id: @reportapproval.id) return elsif @coupon.discount_percent == 100 @reportapproval.report_paid = true @reportapproval.free_coupon_used = true @reportapproval.save! @coupon.coupon_count = @coupon.coupon_count - 1 @coupon.save! redirect_to managers_dashboard_path, :notice => "You have successfully requested a pre-paid report from #{@reportapproval.tenant_last_name} with a 'No-Pay' intro coupon." return else @final_amount = @coupon.apply_discount(@amount.to_i) @discount_amount = (@amount.to_i - @final_amount.to_i) end

| Rails tag_id3v1 mp3 Posted: 17 Apr 2016 07:07 AM PDT Rails 4.2 ap and taglib-ruby gem I have tried a few approaches to tag my audio files using taglib-ruby. I have tried as a carrierwave process, and now, I am trying to tag after_save. My question, if I am doing a callback after_save: def tag_id3v1(tags) TagLib::MPEG::File.open(file.path) do |file| tag = file.id3v1_tag(true) tag.title = :title file.save end
end what should my file path be? I have tried :file, :file_name, and the uploader version url, #{track.mp3.url} I am trying to reopen the saved files and write the tags to the files. Does anyone have any hints on the best approach to do this? |
| Devise Token Auth :authenticate_user! works wrong Posted: 17 Apr 2016 06:52 AM PDT If I add before_action :authenticate_user! to ApplicationController, I get an error: ActionView::Template::Error (undefined method `name' for nil:NilClass): 1: json.data @users, :name, :username
What comes from this file: show.jbuilder json.data @users, :name, :username
My controller: users_controller.rb class UsersController < ApplicationController before_action :authenticate_user! def show @users = User.all render 'users/show' end end
If I remove before_action :authenticate_user! everything works just fine, I get JSON object with the list of users. Why does it happen? Device usually returns 401, but devise_token_auth is trying to trigger my show and fails because can't access database. How to fix this weird behaviour? |

| Redirection using API call Posted: 17 Apr 2016 06:19 AM PDT My rails app is consuming an API, for which I auto submit a form and redirect to another website. I am doing it as below: <%= form_tag "https://www.<somewebsite>.action", method: :post,:protocol => 'https',:id => 'test' do %> <%= hidden_field_tag 'field1', 'value1' %> <%= hidden_field_tag 'field2', 'value2' %> <%= hidden_field_tag 'field3', 'value3' %> <% end %> <script>document.getElementById('test').submit();</script>
This works and opens the other website in another window. Is it by any chance possible to call this redirection in an "iframe" so that the url of the other website is masked. I don't want the user to know that he/she is being redirected to another website. |

| Devise authentication with Angular2 Posted: 17 Apr 2016 05:05 AM PDT I have an Angular2 application which is supposed to work with Rails 5 beta 3 API. This API uses gem 'devise', '~> 4.0.0.rc2' for authentication. In Angular app I have a LoginService a function that sends a POST request to /users/sign_in.json which is handled by Devise::SessionsController. Angular: login.service.ts import {Injectable} from 'angular2/core'; import {Headers, RequestOptions} from 'angular2/http'; import {Observable} from "rxjs/Observable"; import {User} from "./../user"; import {Http, Response} from 'angular2/http'; @Injectable() export class LoginService { constructor (private http: Http) {} private _user_session_url = '/users/sign_in.json'; login (username: string, password: string) : Observable<User> { let body = JSON.stringify({ user: {username: username, password: password} }); let headers = new Headers({ 'Content-Type': 'application/json' }); let options = new RequestOptions({ headers: headers}); return this.http.post(this._user_session_url, body, options).map((data: any) => data.json()).catch(this.handleError) } private handleError (error: Response) { return Observable.throw(error.json().error || 'Server error'); } }
But here is what happenes on my server when I send this request. Started POST "/users/sign_in.json" for 127.0.0.1 at 2016-04-17 14:51:22 +0300 Processing by SessionsController#create as JSON Parameters: {"user"=>{"username"=>"demo", "password"=>"[FILTERED]"}, "session"=>{"user"=>{"username"=>"demo", "password"=>"[FILTERED]"}}} User Load (0.5ms) SELECT "users".* FROM "users" WHERE "users"."username" = $1 ORDER BY "users"."id" ASC LIMIT $2 [["username", "demo"], ["LIMIT", 1]] (0.2ms) BEGIN SQL (0.5ms) UPDATE "users" SET "current_sign_in_at" = $1, "last_sign_in_at" = $2, "sign_in_count" = $3, "updated_at" = $4 WHERE "users"."id" = $5 [["current_sign_in_at", 2016-04-17 11:51:22 UTC], ["last_sign_in_at", 2016-04-17 11:46:51 UTC], ["sign_in_count", 16], ["updated_at", 2016-04-17 11:51:22 UTC], ["id", 4]] (0.9ms) COMMIT Rendered sessions/create.jbuilder (0.3ms) Completed 200 OK in 142ms (Views: 0.9ms | ActiveRecord: 2.1ms) Started GET "/messages.json" for 127.0.0.1 at 2016-04-17 14:51:35 +0300 Processing by MessagesController#show as JSON Completed 401 Unauthorized in 0ms (ActiveRecord: 0.0ms)
So, what basically happens is authentication goes well, but but then on the page refresh I'm still unauthorized. As I understand, the problem is in lack of CSRF token. So my questions are: - How do I get a CSRF token in my Angular app?
- How can I return Devise errors as JSON?

| Two separate has_many tables Posted: 17 Apr 2016 03:15 AM PDT I am having trouble pulling the data I need using two separate many to many associated tables. class User < ActiveRecord::Base # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable has_many :meals has_many :lists end class Meal < ActiveRecord::Base belongs_to :user has_many :meal_lists has_many :lists, through: :meal_lists has_many :meal_ingredients has_many :ingredients, through: :meal_ingredients end class List < ActiveRecord::Base has_many :meal_lists has_many :meals, through: :meal_lists belongs_to :user end class MealList < ActiveRecord::Base belongs_to :meal belongs_to :list end
My end result is to be able to pull out all the meals that are both associated with the list_id and the user_id. So far I have tried @list = @user.lists.create("name: "users list") list.meals.create(name:"List name", user_id: user.id) list.meals.where(user_id: user.id)
I can not seem to figure out how to pull out the meals that are both associated with the user_id and the list_id. EDIT: After reading the first answer here is how I interpreted how to implement it. Keep in mind I am still at the beginning of learning rails and I've been staring at this problem for hours and the more I stare the more obscure it seems. I created a method within the model: Class List < ActiveRecord::Base def self.find_user_meals(user, list) meal = Meal.joins(:meal_lists) user_meal = meal.where(user: user) list_meal = user_meal.where(meal_lists: { list: list } ) return list_meal.distinct end end
and within my controller: def edit @list = List.find(params[:id]) user = current_user @meals = Meal.all @all_user_meals = List.find_user_meals(user, @list) end
And in the view I just iterate over @all_user_meals. I read a little bit into joins and includes after the first answer and seemed to get something to work somewhat within the console. This is not quite working in the app, and I am just trying to wrap my head around it a little bit better. DOUBLE EDIT: So I guess I was just tired and overthinking the problem. What I didn't realize was that the lists are created by one user so I was able to solve this fairly simply. def edit @list = List.find(params[:id]) user = current_user @meals = Meal.all.where(user_id: user.id) @listed_meals = @list.meals end
I can't believe how much time I spent on this. Thanks for spending the time looking at this. Sometimes associations confuse me, other times they seem straightforward. |
| Prevent duplicated code Posted: 17 Apr 2016 12:53 AM PDT I have this test: it "redirects him to vice" do get :show uri_request_1 = Addressable::URI.parse(response.redirect_url) redirects_to_vice_1 = uri_request_1.host == "vice.com" get :show, relative_path: "/Fun/Facts.html" uri_request_2 = Addressable::URI.parse(response.redirect_url) redirects_to_vice_2 = uri_request_1.host == "vice.com" assert redirects_to_vice_1 && redirects_to_vice_2 end
It has a lot of repetition. How can I shorten this test? |
| NoMethodError undefined method `persisted?' for nil:NilClass when signing in with Facebook thru Omniauth/Devise? Posted: 17 Apr 2016 01:36 AM PDT I am putting the finishing touches on a Rails app, and everything was working fine just yesterday, (most of it still is). But now, when I try to sign in with Facebook I get the error NoMethodError undefined method persisted? for nil:NilClass I haven't changed any code in the omniauth_callbacks_controller, or in the User Model, so I do not understand why this is happening all of the sudden. Here's the code in omniauth_callbacks_controller def self.provides_callback_for(provider) class_eval %Q{ def #{provider} @user = User.from_omniauth(env["omniauth.auth"]) if @user.persisted? sign_in_and_redirect @user, event: :authentication set_flash_message(:notice, :success, kind: "#{provider}".capitalize) if is_navigational_format? else session["devise.#{provider}_data"] = env["omniauth.auth"] redirect_to new_user_registration_url end end } end [:twitter, :facebook].each do |provider| provides_callback_for provider end
And in User.rb def self.from_omniauth(auth) identity = Identity.where(provider: auth.provider, uid: auth.uid).first_or_create do |identity| if identity.user == nil user = User.new user.email = auth.info.email || "#{auth.uid}@#{auth.provider}.generated" user.password = Devise.friendly_token[0,20] user.provider = auth.provider if auth.provider == "facebook" user.name = auth.info.name user.username = "FacebookUser" + (1 + rand(1000)).to_s elsif auth.provider == "twitter" user.name = auth.info.name user.username = auth.info.nickname end end identity.user = user end identity.access_token = auth['credentials']['token'] identity.refresh_token = auth['credentials']['refresh_token'] identity.expires_at = auth['credentials']['expires_at'] identity.timezone = auth['info']['timezone'] identity.save identity.user end
I cannot figure out why it WAS working yesterday, but now it's not. Nothing has changed! I'm still accessing it from the same URL, I haven't messed with the API settings on Facebook, or in devise.rb. |
| Having different associations between two models Rails Posted: 17 Apr 2016 12:24 AM PDT I am building an event app that lets users post events, and other users can 'register' themselves as attending that event. I currently have two models, 'User' and 'Article', where article is the event that a user can post. An article belongs_to :user and a user has_many :articles, dependent: :destroy. I am trying to set up a new database to store which users plan to attend an event, in the form of a 'Registration', where it stores a user and the event he plans to attend. This means i need a many to many association between Users and Articles (as a user can attend multiple events, and an event can have multiple attendees). But will this not conflict with the original setting that states an article belongs to a single user? How do i set this up so my associations dont interfere? |

| Rails 4 Set Value of the logged in User by default before create Posted: 16 Apr 2016 11:58 PM PDT I have the following models members (id, name, company_id..) companies (id, name, ...) campaigns (id, company_id, ...)
When creating a Campaign i have the following def create @campaign = Campaign.new(campaign_params) if @campaign.save redirect_to campaigns_path(@campaign) else render :new end end
i have a helper method from the AppController called current_company whose id i want to set to @campagin.company_id which is the best way to set the default logged in users company.id to every campaign created? can i traverse through current_company and build a query like this? @campaign = current_company.campaign.new(campaign_params)

| Rails 4: Integrating Disqus Posted: 17 Apr 2016 12:46 AM PDT I'm trying to figure out how to use the disqus-rails gem in my Rails 4 app. https://github.com/sandric/disqus_rails The instructions say to include an access token in an initialiser. I can't figure out how to generate an access token. I have setup my app and channel in disqus, but can't find the token. Where do I go to get the access token for disqus? |
| Devise update_without_password gives ForbiddenAttributesError Posted: 16 Apr 2016 11:18 PM PDT I added additional fields to my user model, then updated the configure_account_update_params method accordingly. Everything was working until I wanted users to be able to update their information without having to input their current password. So I removed the field for the view and changed the update method in the RegistrationsController This is my controller, I'm not sure if I'm missing something class Users::RegistrationsController < Devise::RegistrationsController before_filter :configure_account_update_params, only: [:update] def update resource.update_without_password(resource_params) end # If you have extra params to permit, append them to the sanitizer. def configure_account_update_params devise_parameter_sanitizer.for(:account_update) << [:first_name, :last_name, :country, :phone_number, :gender, :birthdate] end end
