Validation doesn't work as expected for related models in Rails 4? Posted: 11 Jun 2016 05:38 AM PDT I use one form to enter data for two models. When I save parent model (Tenant) the child model (User) also gets saved, but only if I don't validate tenant_id in User model. If I do validates :tenant_id, presence: true in User model then validation error "Users tenant can't be blank" is displayed. Any ideas why? Tenant model: class Tenant < ActiveRecord::Base has_many :users, dependent: :destroy, inverse_of: :tenant accepts_nested_attributes_for :users before_validation do self.status = 0 self.name = name_orig.upcase email.downcase! end validates :name_orig, presence: true, length: { maximum: 255 } validates :name, uniqueness: { case_sensitive: false } VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i validates :email, presence: true, length: { maximum: 255 }, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false } validates :status, presence: true end User model: class User < ActiveRecord::Base belongs_to :tenant, inverse_of: :users validates_presence_of :tenant before_validation do self.status = 0 self.email = email.downcase end VALID_USERNAME_REGEX = /\A\w+\s?\w*\z/i validates :name, presence: true, length: { maximum: 50 }, format: { with: VALID_USERNAME_REGEX }, uniqueness: { case_sensitive: false } VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i validates :email, presence: true, length: { maximum: 255 }, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false } has_secure_password validates :password, presence: true, length: { minimum: 6 } validates :tenant_id, presence: true validates :status, presence: true end Tenant controller: class TenantsController < ApplicationController def new @tenant = Tenant.new @tenant.users.build end def create @tenant = Tenant.new(tenant_params) @tenant.save if @tenant.save flash[:success] = "Welcome!" redirect_to @tenant # redirects to tenant profile else render 'new' end end private def tenant_params params.require(:tenant).permit(:name_orig, :email, users_attributes: [:name, :email, :password, :password_confirmation]) end end

Pundit scoping usage empty results Posted: 11 Jun 2016 05:36 AM PDT Suppose I have a scenario where we have Users and each user can create their own Projects. I'm trying to limit the Show action of my Rails controller to only allow admin or the owner of the project to be able to go through Show action. The problem I am facing is, perhaps I'm misunderstanding on how to use Scopes in Pundit. My Show action looks like this: def show project = policy_scope(Project).find_by({id: project_params[:id]}) if project render json: project else render json: { error: "Not found" }, status: :not_found end end My Pundit Scope class looks like this: class Scope < Scope def resolve if @user.admin? scope.all else # obviously, if non-matching user id, an ActiveRelation of # empty array would be returned and subsequent find_by(...) # would fail causing my controller's 'else' to execute # returning 404 instead of 403 scope.where(user_id: @user.id) end end end In my Rails test, I am trying to assert that non-project owner should receive a 403 forbidden: test "show project should return forbidden if non admin viewing other user's project" do # "rex" here is not the owner of the project get project_path(@project.id), headers: @rex_authorization_header assert_response :forbidden end My test is failing. I am getting the error: Failure: ProjectsControllerTest#test_show_project_should_return_forbidden_if_non_admin_viewing_other_user's_project [/Users/zhang/App_Projects/LanceKit/Rails_Project/LanceKit/test/controllers/projects_controller_test.rb:40]: Expected response to be a <403: forbidden>, but was a <404: Not Found>. Expected: 403 Actual: 404 I don't quite feel like I'm using Pundit correctly. Should I be using Pundit's authorize project instead of using policy_scope(Project)... for the Show action? I was expecting the scope.where(...) to detect the incorrect user id and return some error saying 'you are not authorized to view this resource' rather than returning results.

Rails + Angular JS + Socket IO Posted: 11 Jun 2016 05:13 AM PDT I try to connect my Grape API + Angular JS to socket.io and I have got some errors, preventing me to do it. Can you please help me? I have downloaded this client https://github.com/socketio/socket.io-client. And also this plugin https://github.com/btford/angular-socket-io. Added to my app.js dependency 'btford.socket-io'. And created factory app.factory('socket', function ($rootScope) { var socket = io.connect(); return { on: function (eventName, callback) { socket.on(eventName, function () { var args = arguments; $rootScope.$apply(function () { callback.apply(socket, args); }); }); }, emit: function (eventName, data, callback) { socket.emit(eventName, data, function () { var args = arguments; $rootScope.$apply(function () { if (callback) { callback.apply(socket, args); } }); }) } }; }); But I continue to get same error: ActionController::RoutingError (No route matches [GET] "/socket.io") I did not include line script src="/socket.io/socket.io.js" I included only socket.js and socket.io.js to my lib

Create Metafield for product in shopify rails Posted: 11 Jun 2016 05:00 AM PDT I am new to shopify application development and working on to create app which add time block on product page. I have created rails app with form on home#index page as below <%= form_tag('/home/save_product_options', id: "form_#{product.id}", 'data-shopify-app-submit' => 'unicorn_form_submit') do %> <%= hidden_field_tag :key %> <%= hidden_field_tag :product_id, product.id %> <%= hidden_field_tag :value %> <%= check_box_tag :product_timer, false, false, onclick: "add_key_value('#{product.id}')" %> Add timer to product <br> <%= submit_tag 'Save', disabled: true %> <% end %> So when admin select checkbox and submit, a metafield should be created for above product. But it always return error 500 on form submit even though save_product_options path exists in application Please suggest any direction

subqueries as columns in select same table but different condition and result Posted: 11 Jun 2016 05:03 AM PDT I have two tables #orders | id | item_id | quantity | ordered_on | |----|---------|----------|------------| | 1 | 1 | 2 | 2016-03-09 | | 2 | 1 | 2 | 2016-03-12 | | 3 | 4 | 3 | 2016-03-15 | | 4 | 4 | 3 | 2016-03-13 | #stocks | id | item_id | quantity | enter_on | expire_on | |----|---------|----------|------------|------------| | 1 | 1 | 10 | 2016-03-07 | 2016-03-10 | | 2 | 1 | 20 | 2016-03-11 | 2016-03-15 | | 3 | 1 | 20 | 2016-03-14 | 2016-03-17 | | 4 | 4 | 10 | 2016-03-14 | NULL | | 5 | 4 | 10 | 2016-03-12 | NULL | So I'm trying to create a view to show the orders along with its closest stocks enter_on like this (I'm using include_after and include_before to give an overview on which date I want to exclude the item that's preordered, so the stock would reflect correctly) include_after is always going to be the stock that came in but not expired yet, if expired, show NULL, include_before will always show the next incoming stock enter_on, unless there's an expire_on that's earlier than the next enter_on | item_id | quantity | ordered_on | include_after | include_before | |---------|----------|------------|---------------|----------------| | 1 | 2 | 2016-03-09 | 2016-03-07 | 2016-03-10 | | 1 | 2 | 2016-03-12 | 2016-03-11 | 2016-03-14 | | 4 | 3 | 2016-03-13 | 2016-03-12 | 2016-03-14 | | 4 | 3 | 2016-03-15 | 2016-03-14 | NULL | So this is what I came up with SELECT o.item_id, o.quantity, o.order_on, ( SELECT COALESCE(MAX(s.enter_on), NULL::DATE) FROM stocks s WHERE s.enter_on <= o.order_on AND s.item_id = o.item_id ) as include_after, ( SELECT COALESCE(MIN(s.enter_on), NULL::DATE) FROM stocks s WHERE s.enter_on > o.order_on AND s.item_id = o.item_id ) as include_before FROM orders o It works fine (I haven't included the expire_on part), but I'm worrying about performance issue for using two subqueries in the select. Does anyone have some alternative suggestions? Let me know if the question is unclear, the problem is a bit chaotic. Thanks!

rails nginx and puma error Posted: 11 Jun 2016 04:44 AM PDT I've just deployed a new app and got some errors. my config files looks like the ones in here: https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma puma log: === puma startup: 2016-06-11 13:10:07 +0200 === !

Rails / Shared strong parameters' definition between two controllers Posted: 11 Jun 2016 05:53 AM PDT having two items_controller, one for the api (in app/controllers/api/) and one for the backend (in app/controllers/backend) The strong parameters are quite long (20 fields or something) and prompt to evolve a bit. That would not be impossible to maintain this list in both controllers, but as the needs are more or less the same on the create/updates actions, I'd be looking into sharing the strong parameters definition in a separate file that would be shared to both I've tried to inherit those two with a super controller including only the strong parameter definition : class SharedItemsController < ApplicationController private # not knowing all the prerequisites of this, I tried also using protected instead of private; same result def item_params .... end end end class Frontend::ItemsController < SharedItemsController ... end class Api::ItemsController < SharedItemsController ... end No success, I'm stuck with unpermitted parameters Hope to get some tips on this one here on SO; best

How to elegantly return hash with one value modified in Ruby? Posted: 11 Jun 2016 04:51 AM PDT I have this method in Rails that returns params: def customer_params params.require(:treatment_booking).require(:customer) end I want to remove whitespace from :phone in place and return the whole hash. I can do it like so: params.require(:treatment_booking).require(:customer).merge(:phone => params[:treatment_booking][:customer][:phone].gsub(/\s+/, "")) .. but I think it's a bit not elegant since I have to reference the whole path to a hash that I already calling methods on. Is there a better way? I think this is Ruby question, but Rails answer would be just as valid.

How to access spree commerce website from external IP address on google compute engine Posted: 11 Jun 2016 04:31 AM PDT I am new to Ruby/Rails/Spreecommerce but eventually following the tutorials that I can find on the internet, I successfully made the Spree commerce shop website on localhost:3000. I am using Google Cloud Platform (GCP) for this custom VM: CentOS7, Apache, MySQL, PHP7, Ruby latest, Rails latest, VNC server to access the VM etc. My question is, How do I access my shop with external w.x.y.z IP that GCP has assigned me? When I access this IP from outside I get the usual Apache working Test page ok (assume on default port 80?). I believe Apache server is running too along with rails server. Currently on VM only, I have the access to localhost:3000 which shows my website perfectly ok. Am I missing some config to tweak, so that the outside world can access on w.x.y.z IP? Once this works then I plan to change the nameservers for my actual domain. I had a look at the pre-made solution like Bitnami Spree but I keep away from branding usually hence using my own CentOS7 from scratch. thanks!

How to connect two tables by using ActiveRecord? Posted: 11 Jun 2016 05:29 AM PDT I'm trying RoR Active Records with Association. And trying to connect two tables, which is restaurants and restaurant_translations. These are split for multi-language support. Here's the definition of those two tables. class CreateRestaurants < ActiveRecord::Migration def change create_table :restaurants do |t| t.string :restaurant_id t.string :type t.string :genre t.string :url t.string :fb t.string :mailaddr t.timestamps null: false end end end class CreateRestaurantTranslations < ActiveRecord::Migration def change create_table :restaurant_translations, {:id => false} do |t| t.integer :id t.string :restaurant_id t.string :name t.string :address t.string :tel t.text :description t.string :lang t.timestamps null: false end execute "ALTER TABLE restaurant_translations ADD PRIMARY KEY (id,lang);" end end And the Models. class Restaurant < ActiveRecord::Base has_many :restaurant_translations end class RestaurantTranslation < ActiveRecord::Base self.table_name = 'restaurant_translations' belongs_to :restaurant end And then here's the controller which creates my headache. class RestaurantController < ApplicationController def list @restaurants = Restaurant.all @restaurants = @restaurants.restaurant_translation.find_by(lang: "en") end end So error shows like this. Could you tell me how to write? @Pavan 's advice causes some another errors like this. BTW, my view is like this. It's .slim file. h1 = t :restraunt_list_title table thead tr th = t :restraunt_list_type th = t :restraunt_list_name th = t :restraunt_list_url th = t :restraunt_list_genre th = t :restraunt_list_addr tbody - @restaurants.each do |restaurant| tr td = restaurant.restaurant_type td = restaurant.restaurant_translations.first.restaurantname td = link_to 'here', restaurant.url td = restaurant.genre td = restaurant.restaurant_translations.first.address br

The bucket you are attempting to access must be addressed using the specified endpoint Posted: 11 Jun 2016 04:22 AM PDT I'm using paperclip 5.0.0.beta2 in my latest rails (4.2.6) project. The application is hosted on Heroku. I can upload an image and it seems to be stored in a bucket on Amazon S3. However in the browser the image appears to have a broken url, although it's point to the bucket on Amazon S3, the url is: http://s3.amazonaws.com/gigbnb/profiles/profile_pics/000/000/002/small/anthony_candaele-300x300.jpg?1464956858 When I enter this url in the browser, I get an xml page with this error message: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint. It looks like there is an issue with the S3 endpoint. However I set the region (eu-west-1) in configuration file: config/environments/production.rb config.paperclip_defaults = { storage: :s3, s3_region: ENV.fetch('AWS_REGION'), s3_credentials: { bucket: ENV.fetch('S3_BUCKET_NAME'), access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'), secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'), } } My Github repository is at: https://github.com/acandael/gigbnb Does anyone have an idea what's going on? Thanks for your help, Anthony

How can I make a dropdown menu in rails with the option to display an image? Posted: 11 Jun 2016 04:21 AM PDT I want to make a simple dropdown menu which lists some options (for example: tiger and lion). When I press the submit button, i want to reload the page, the dropdown menu should be still there and the image of one of the options (images are in app/assets/images) should be below. I don´t know how to define the change action in the controller, that after pressing the submit button, the page reloads and the correct image is shown. Also i am not quite sure if my dropdown menu is correct. I would be very glad if you have some ideas. Thanks in advance. This is my view so far: <h1>Animals</h1> <%=form_tag change_animals_path do %> <select> <option>lion</option> <option>tiger</option> </select> <%= submit_tag "Switch Animal", class: "btn btn-lg btn-first"%> <% end %> <br> <div align="center"> <img src="/assets/<%= @images_t %>"> </div> </div> This view has a dropdown menu and shows the tiger image. This is the def index of the animals controller: def index @images_t = ("tiger.jpg") @images_l = ("lion.jpg") end def change ????? redirect_to animals_path end

Rails 4 ActiveRecord Exclusion Validation for Association Posted: 11 Jun 2016 05:15 AM PDT I'm trying to validate an association in my model and exclude a certain object for the validation, but can't seem to get it to work. Here's my code: validates :user, presence: true, exclusion: { in: [:lot_high_bidder] } I imagine it's trying to do a direct comparison of :user with the symbol :lot_high_bidder which will obviously always fail, but does that mean I can't use a method name in an exclusion validator or is the syntax just wrong?

Should i make a seperate app to send push notifications to 40-50k users in RoR App or use background jobs Posted: 11 Jun 2016 05:12 AM PDT I have a rails application that is in fact a backend of a popular IOS application which have a user base of 200k users who need to be notified time to time. Daily 40-50k users will be notified using push notifications. These push notifications will be realtime and scheduled ones. eg: if a new users signs up he will be notified within few seconds. eg: scheduled notifications will run at 10 pm daily with limited users ranging 10k-30k or sometimes more upto 100k. I also will be doing business reporting to generate list of users fulfilling certain criteria and it requires firing mysql queries that could take upto 1-2 minutes of time. My area of concern is should i have a seperate application with seperate mirror db to send push notifications to these users so my IOS users doesnt feel lag while using this application when push notifications are triggered or business reporting query is triggered. Or should i use background jobs like Rails Active job, Sidekiq or Sucker Punch to perform push notifications and triggering business reporting queries. Is background jobs in rails so powerful that it can manage this condition and doesn't let App users to feel lag in experience. My application stack is: Rails: 4.1.6 Ruby: 2.2 DB: Mysql PaaS: AWS Elastic Beans IOS Push gem: Houston

Ruby on rails - Simple form not displaying errors for radio select. Other errors display fine Posted: 11 Jun 2016 03:56 AM PDT I have a user registration form (Devise) with 4 elements; Username, email, password and 'user type'. User type is a boolean and is displayed as a radio select on the form. Errors for Username, email and password show no problem, but I get no errors showing if a user doesn't select one of the radio buttons. Validation IS in place, and the form won't send without one of the radio buttons selected, but I get no errors. The form: <%= simple_form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %> <%= f.error_notification %> <div class="role-selector"> <p class="type-sel-txt"><%= t('front.whattype') %></p> <label for="artistuser"> <%= f.radio_button :artist, "1", :id => "artistuser" %> <span class="artistuser-sel"><%= t('front.bandm') %></span> </label> <label for="eventuser"> <%= f.radio_button :artist, "0", :id => "eventuser" %> <span class="eventuser-sel"> <%= t('front.evento') %></span> </label> </div> <%= f.input :username, required: true, autofocus: true, placeholder: t('forms.login.user'), label: false %> <%= f.input :email, required: true, placeholder: t('forms.login.email'), label: false %> <%= f.input :password, required: true, placeholder: t('forms.login.password'), label: false %> <div id="passcheck"></div> <%= f.button :submit, t("forms.login.signup"), id: "register-btn" %> <% end %> User.rb: validates_inclusion_of :artist, in: [true, false], on: :create Registration works without a problem, my only issue is the error not showing. I'm not sure if it is necessary to paste any more of my code, but if so I'll update with whatever is required.

Time in DB compared to current time Posted: 11 Jun 2016 03:00 AM PDT I have a couple of stores that I'd like to display if they're open or not. The issue is that I have my current time. Time.current => Sat, 11 Jun 2016 11:57:41 CEST +02:00 and then if I for example take out the open_at for a store I get: 2000-01-01 00:00:00 +0000 so what I have now is: def current_business_hour(current_time: Time.current) business_hours.where('week_day = ? AND open_at <= ? AND close_at >= ?', current_time.wday, current_time, current_time).first end and then I check if a current_business_hour is present. However this is calculating it wrong by what seems like two hours. The open_at and close_at should be within the time zone of Time.current.

Can't install rails-assets-tether Posted: 11 Jun 2016 02:50 AM PDT When I try to install rails-assets-tether, I get an error. Retrying fetcher due to error (2/4): Bundler::Fetcher::CertificateFailureError Could not verify the SSL certificate for http://rails-assets.org/.

Foundation CSS with Rails - restricting certain JS elements from loading Posted: 11 Jun 2016 01:52 AM PDT Foundation is a great CSS framework, but when used with Rails as a gem it loads up a lot of unnecessary js elements, such as accordions, etc: GET /assets/foundation/foundation.alert.js GET /assets/foundation/foundation.js GET /assets/foundation/foundation.abide.js GET /assets/foundation/foundation.accordion.js GET /assets/foundation/foundation.clearing.js GET /assets/foundation/foundation.dropdown.js GET /assets/foundation/foundation.joyride.js GET /assets/foundation/foundation.interchange.js GET /assets/foundation/foundation.magellan.js GET /assets/foundation/foundation.reveal.js GET /assets/foundation/foundation.offcanvas.js GET /assets/foundation/foundation.tab.js GET /assets/foundation/foundation.orbit.js GET /assets/foundation/foundation.topbar.js GET /assets/foundation/foundation.slider.js GET /assets/foundation/foundation.tooltip.js GET /assets/foundation.js GET /assets/foundation/foundation.equalizer.js I would like to find a way to get in the middle of this process and remove a bunch of these elements to get a small performance boost. I understand that I need to swap the //= require foundation line in my application.js file with the list of the elements I need but I am having trouble finding such list and its correct spelling.

coffeescript class - calling calling one class method from an other Posted: 11 Jun 2016 01:14 AM PDT I have rewritten my embedded JS in my rails app to coffeescript..and I am new to coffeescript... My approach is a mix of these articles: approach one approach two My code: s = undefined class App.PhotoLike settings: modalElement: $('#myModal') likeButtonId: '#like' photo_id: $('.image_info').attr('photo_id') numberOfLikes: $('#likes_num') constructor: (@el) -> console.log('constructor called') s = @settings @bindUIActions() return this bindUIActions: -> console.log('bindUIActions called') $('#myModal').on 'click', '#like', -> likePhoto() $(document).on "page:change", -> pageChange() pageChange: -> console.log('pageChange called') photo = new App.Photo likePhoto: -> console.log('likePhoto called') url = '/photos/' + s.photo_id + '/like' $.get url, (data) -> s.numberOfLikes.html data['likes'] + ' likes' $(s.likeButtonId).toggleClass 'btn-success' This is part of a model that gets loded with ajax and once that call succeeds i do i create the above class (instance of): new (App.PhotoLike) My problem. The modal gets loaded an all seems good. But when I trigger the event: $('#myModal').on 'click', '#like', -> likePhoto() I get: photo.like.self-942fcd8….js?body=1:25 Uncaught ReferenceError: likePhoto is not defined so, it does not know the likePhoto function. I have tried calling this.likePhoto and @likePhoto, but this refers to the button element that triggers the event. So how do I do this? Other approaches are welcome. i not really sure that I need the classes...but I really want structured code...

Ruby: Confused about how to make sense of this code Posted: 11 Jun 2016 02:07 AM PDT I'm a little confused about one part of this code. In line 7 I have commented below. 01:states_file = File.open("states_abbrev.txt") 02:states = {} 03:while ! states_file.eof? 04: first = states_file.gets.chomp 05: #"ALABAMA,AL" 06: data = first.split(",") 07: states[ data[0] ] = data[1] #This line here. 08:end 09:puts states.inspect 10: 11:states_file.close Line 5 is and example of what each line is like in the states_abbrev.txt file. Just a state, a comma, abbreviation, and a carriage return. All 50 states are in the file. As you can see on line 7 the data[0] key seems to be overwritten by data[1]. So why is it when i run this code data[0] is still the key, and data[1] becomes the value?

How do I model Child belongs to class Posted: 10 Jun 2016 11:31 PM PDT create_table "children", force: :cascade do |t| t.string "name" t.date "dob" t.string "child_class" t.string "section" t.integer "parent_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end This is the schema I have for the Child model. child_class values are getting stored as "1", "2" ..

Rails Ajax dropdown menu - no response Posted: 10 Jun 2016 11:38 PM PDT So I've solved almost all my problems with this little program I'm writing: The only one left, that I'm just beating my head against, goes like this. It's your standard two dropdown menus, select an item on one to populate the other. In my view: <%= select_tag( :contractor_id, options_from_collection_for_select(Contractor.all, "id", "appointment_record"), :'data-remote' => 'true', :'data-url' => url_for(:controller => 'contractors', :action => 'getdata'), :'data-type' => 'json') %> <%= select_tag( :company_id, # name of selectbox ) %> In my controller: def getdata @data_from_select1 = params[:contractor_id] @data_for_select2 = Company.where(:id => @data_from_select1).all # render an array in JSON containing arrays like: # [[:id1, :name1], [:id2, :name2]] render :json => @data_for_select2.map{|c| [c.id, c.name]} end In my application.js: $(document).ready(function() { $('#contractor_id').live('ajax:success', function(evt, data, status, xhr) { var selectbox2 = $('#company_id'); selectbox2.empty(); $.each(data, function(index, value) { // append an option var opt = $('<option/>'); // value is an array: [:id, :name] opt.attr('value', value[0]); // set text opt.text(value[1]); // append to select opt.appendTo(selectbox2); }); }); }); In my routes: get 'getdata' => 'contractors#getdata' And I just don't get anything at all populating company.id. Not ever! Contractor.id populates just fine, all the names fill out there, but nothing is returned to company.id I'm a huge noobie, so I'm sure I'm missing something here. What??
