| 'let' not memoize values in rsepc Posted: 15 Jul 2016 07:14 AM PDT I have a user model, who have a many-to-many relationship whit itself: user A add user B as a friend, and automatically, user B becomes friend of user A too. Performing the following steps in the rails console: 1) Create two users and save them: 2.3.1 :002 > u1 = User.new(name: "u1", email: "u1@mail.com") => #<User _id: 5788eae90640fd10cc85f291, created_at: nil, updated_at: nil, friend_ids: nil, name: "u1", email: "u1@mail.com"> 2.3.1 :003 > u1.save => true 2.3.1 :004 > u2 = User.new(name: "u2", email: "u2@mail.com") => #<User _id: 5788eaf80640fd10cc85f292, created_at: nil, updated_at: nil, friend_ids: nil, name: "u2", email: "u2@mail.com"> 2.3.1 :005 > u2.save => true
2) Add user u2 as friend of u1: 2.3.1 :006 > u1.add_friend u2 => [#<User _id: 5788eaf80640fd10cc85f292, created_at: 2016-07-15 13:54:04 UTC, updated_at: 2016-07-15 13:55:19 UTC, friend_ids: [BSON::ObjectId('5788eae90640fd10cc85f291')], name: "u2", email: "u2@mail.com">]
3) Check their friendship: 2.3.1 :007 > u1.friend? u2 => true 2.3.1 :008 > u2.friend? u1 => true
As we can see, the "mutual friendship" works. But in my tests that doesn't happen. Here are my tests: require 'rails_helper' RSpec.describe User, type: :model do let(:user) { create(:user) } let(:other_user) { create(:user) } context "when add a friend" do it "should put him in friend's list" do user.add_friend(other_user) expect(user.friend? other_user).to be_truthy end it "should create a friendship" do expect(other_user.friend? user).to be_truthy end end end
Here are the tests result: Failed examples: rspec ./spec/models/user_spec.rb:33 # User when add a friend should create a friendship
The only reason that I can see to the second test is failing is because my let is not memoizing the association to use in other tests. What am I doing wrong? Here is my User model, for reference: class User include Mongoid::Document include Mongoid::Timestamps has_many :posts has_and_belongs_to_many :friends, class_name: "User", inverse_of: :friends, dependent: :nullify field :name, type: String field :email, type: String validates :name, presence: true validates :email, presence: true index({ email: 1 }) def friend?(user) friends.include?(user) end def add_friend(user) friends << user end def remove_friend(user) friends.delete(user) end end

| Can a ruby class method inherit from another class? Posted: 15 Jul 2016 06:10 AM PDT I read here that a ruby class can only inherit from one class, and can include modules. However, the devise module defines controllers like this: class Users::PasswordsController < Devise::PasswordsController ... end

How is it that a method in a class inherits from another class? |

| Rails 4 app with devise and mailgun on heroku does not send confirmation but resends it Posted: 15 Jul 2016 05:18 AM PDT My rails 4 app on heroku in production uses mailgun addon for sending mail. It does not send confirmation emails, but sends reconfirmations (when I click on "didn't receive confirmation instructions" on the sign up page. This was working a few weeks back, but it is not working now. I have checked the configuration is correct in my production.rb (and it is obviously correct because resend is also using the same - mailgun - addin). I have seen other threads that talk about similar issues, and fixed some of the issues in production based on this (like replacing the heroku env vars with the domain instead of default sandbox params). But still no dice. The reconfirmation email appears in the logs, but the confirmation email does not. Here are the heroku logs for the new user creation - notice the conspicuous absence of the email being sent.

| Limit association based on rich relation attributes Posted: 15 Jul 2016 06:02 AM PDT first question for me here! Im trying to assign 'key companies' to my users. These are found in a many-to-many rich join table. On this table there are attributes like new, key, active and so forth. I want to assign companies to users in a long list and for that Im using SimpleForm. Everything is working excepts that I want to filter out and limit the association relation based on the attributes on the rich relation. I have company relations for each user but not all of them are akey-relation or a new-relation for example. I only want the association being key to show up and not touch the other ones. I also want to set the attribute active to true when Im assigning these companies to the users. My code looks like this now: user.rb class User < ActiveRecord::Base has_many :company_user_relationships has_many :companies, through: :company_user_relationships
company.rb class Company < ActiveRecord::Base has_many :company_user_relationships has_many :users, through: :company_user_relationships
schema.rb create_table "company_user_relationships", force: true do |t| t.integer "company_id" t.integer "user_id" t.boolean "key" t.boolean "active" t.datetime "last_contacted" t.string "status_comment" t.datetime "created_at" t.datetime "updated_at" t.integer "status" t.boolean "new" end
users_controller.rb def assign_key_companies User.update(params[:users].keys, params[:users].values) redirect_to(:back) end
view = form_for :user_companies, url: assign_key_companies_users_path, html: {:method => :put} do |f| - users.each do |user| = simple_fields_for "users[]", user do |u| tr td.col-md-4 = "#{user.first_name} #{user.last_name}" td.col-md-8 = u.association :companies, label: false, collection: @key_company_candidates, input_html: {data: {placeholder: " Assign key companies"}, class: 'chosen-select'} = submit_tag "Save key companies", class: "btn btn-success pull-right"
I basically want to only show user.companies.where(key: true) and the SQLCOMMIT to always put the key-field to true when updating the record. How can i filter out to only affect the associations I want? |

| Omnicontacts redirect_uri: facebook, hotmail, yahoo Posted: 15 Jul 2016 04:21 AM PDT I am using the omnicontacts gem so that users can invite their contacts on my website. I have set it up successfully for Google. I have setup an omnicontacts controller with the contacts_callback method as suggested by the gem's readme. and a route: get "/contacts/:importer/callback" => "omnicontacts#contacts_callback" At the initializer of omnicontacts.rb I have the followings: require "omnicontacts" Rails.application.middleware.use OmniContacts::Builder do importer :gmail, "hidden-client-key", "hidden-secret-key", {redirect_path: "/contacts/gmail/callback"} importer :facebook, "hidden-client-key", "hidden-secret-key", {:redirect_path => "/contacts/facebook/callback" } importer :hotmail, "hidden-client-key", "hidden-secret-key", {redirect_path: "/contacts/hotmail/callback"} end
The last two (facebook and hotmail) according to the gem's readme file do not need a redirect_path but just in case I tested both with it or not and I still get an error that the redirect_uri is invalid. As I was searching for a solution I found a place that the :redirect_path was instead :callback_path and tried that as well but no luck. On the Microsoft app (for hotmail) I was getting a longer description on the error which was: The provided value for the input parameter 'redirect_uri' is not valid. The expected value is 'https://login.live.com/oauth20_desktop.srf' or a URL which matches the redirect URI registered for this client application. As a result I went on and registered a redirect URI for this client application. The URI was http://example.com/contacts/hotmail/callback which matches the callback path. Still, getting the same error. Any clue? |
| break if method takes more than 30sec time to execute Posted: 15 Jul 2016 04:51 AM PDT I benchmarked the execution time for method tests.each do |test| time = Benchmark.realtime { method(test) } end def method(test) code end
Which is returning time in seconds But what I want is to break the loop if this method is taking more than 30 sec of execution time. suggest a clean way to do it. |

| [SOLVED]How to change the path for edit user from edit_user to account_settings? Posted: 15 Jul 2016 04:11 AM PDT The default path for editing user is edit_user_path. Is it possible to customize the path so that it will become account_settings_path? I already did the same for user sign up. Instead of the default new_user_path, I was able to changed it to signup_path. But the edit user is different because the URI Pattern in rails routes is /users/:id/edit so I'm confused what code to write in routes.rb unlike the signup_path where I can just write the codes: get '/signup', to: 'users#new' post '/signup', to: 'users#create'
which adds a new routes in rails routes to signup. edit: I solved it already using the code: get '/users/:id/account_settings', to: 'users#edit', as: 'account_settings'

| Rails - bookings not saving to database Posted: 15 Jul 2016 03:39 AM PDT I'm building an Event site using Rails. When creating an event the user is able to offer both paid and free events. It appears that a booking_id is being allocated only to paid events not for free events. I've checked my console and this is definitely the case. This is obviously causing issues and I'm not quite sure how to resolve. Here's my code - bookings_controller.rb class BookingsController < ApplicationController before_action :authenticate_user! def new # booking form # I need to find the event that we're making a booking on @event = Event.find(params[:event_id]) # and because the event "has_many :bookings" @booking = @event.bookings.new # which person is booking the event? @booking.user = current_user @booking.quantity = @booking.quantity @total_amount = @booking_quantity.to_f * @event_price.to_f end def create # actually process the booking @event = Event.find(params[:event_id]) @booking = @event.bookings.new(booking_params) @booking.user = current_user #@total_amount = @booking.quantity.to_f * @event.price.to_f Booking.transaction do @booking.save! @event.reload if @event.bookings.count > @event.number_of_spaces flash[:warning] = "Sorry, this event is fully booked." raise ActiveRecord::Rollback, "event is fully booked" end end if @booking.save # CHARGE THE USER WHO'S BOOKED # #{} == puts a variable into a string Stripe::Charge.create(amount: @event.price_pennies, currency: "gbp", card: @booking.stripe_token, description: "Booking number #{@booking.id}") flash[:success] = "Your place on our event has been booked" redirect_to event_path(@event) else flash[:error] = "Payment unsuccessful" render "new" end if @event.is_free? @booking.save! flash[:success] = "Your place on our event has been booked" redirect_to event_path(@event) end end private def booking_params params.require(:booking).permit(:stripe_token, :quantity) end end
Booking table - create_table "bookings", force: :cascade do |t| t.integer "event_id" t.integer "user_id" t.string "stripe_token" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.integer "quantity" end
I've added @booking.save! into the create method for free events but no change. I've also added the transaction code block in order to avoid over-booking but this only works for paid events. Any assistance, appreciated. |
| Rails configure application to have url prefix Posted: 15 Jul 2016 05:14 AM PDT I feel like this should not be all that difficult, but I cannot find any solutions that seem to work with Rails4 My setup - I have a proxy server (Kong) that directs to various services behind it based on path.
myapp.com/app1/ is redirected to http://app1_address:PORT/ (notice /app1 is stripped)- same for
myapp.com/app2 app2 is a Rails 4 application and it works just fine when browsing to specific, but its relative routing is completely off. For example, link_to or url_for links to controllers or actions all redirect to the wrong links.
For example, I have a logout link that has a path of /logout on app2, but redirecting the user to /logout is incorrect. They need to be routed to /app2/logout. How can I configure the Rails app to add a prefix to all routes? I have tried: config.action_controller.relative_url_root = '/app2'
As well as this: config.relative_url_root = '/app2'
And this in config.ru map <MyAppName>::Application.config.relative_url_root || "/" do run Rails.application end
Any ideas for how to make this work? |
| How to make my project choose rbenv version of ruby Posted: 15 Jul 2016 03:38 AM PDT I am planning to run ruby 2.3.1 version with Rails 5 on Mac OSX. 1 I installed rbenv then install ruby version 2.3.1. rbenv version 2.3.1 (set by /D/testProject/.ruby-version)
2 Update gem gem update --system Latest version currently installed. Aborting.
3 System ruby version: ruby -v ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
But when i run gem update rails, i got ERROR: Error installing rails: activesupport requires Ruby version >= 2.2.2.
So my question is how to make the project choose rbenv version of ruby? Then i can update to Rails 5. EDIT I have ran rbenv local 2.3.1 (.ruby-version was created) already. But still can't update to Rails5 Thank you! |
| How to have a select_tag with an "selected disabled hidden" option? Posted: 15 Jul 2016 05:04 AM PDT I want to have a select_tag that includes a field which displays "Please select" to the user. This field must not be selectable by the user. Here is a jsfiddle of what I want to have : http://jsfiddle.net/gleezer/pm7cefvg/1/ In Rails, I tried to do this : <%= select_tag(:userchief, options_for_select(@options_for_selectUsers, {:selected => "x1", :disabled => "x1", :hidden => "x1"})) %>
(@options_for_user is an array which contains multiple key/value elements) But when I check the source code of my page, I can see this for my option : <option disabled="disabled" selected="selected" value="x1">Select</option>
That is not what I want to have, the x1 select option appears in the dropdown menu of the select because the hidden field is not present. How can I do to obtain the same result as I can see in the jsfiddle link ? |
| Should I use different models for authentication Posted: 15 Jul 2016 03:24 AM PDT I have a rails project which is going to have two types of users - Staff and Parents. In general, the website will have two different sections where parents can view student details and another where staff can update student details. A staff may however also be a parent. What would the best strategy in this case be - - Seperate model for Staff and Parents
- Single user model with an is_staff and is_parents fields to separate the two
