| Couldn't find Manufacturer with 'id'= (blank) Posted: 22 Jul 2016 08:09 AM PDT I am trying to create a web application to practise my Ruby on Rails skill. I have a few entities in my database manufacturers, models, tints, prices manufacturers {id, name} - stores the make of the car
models {id, manufacturer_id, name} - stores the models of the car
tints {id, manufacturer_id, model_id, front, sides, rear} - stores the length of tint required
prices {id, description, price } - stores the price of the item
I created a page to generate a quotation for window tinting. The page includes drop-down menus to let user to select manufacturer, model, type of film(front), type of film(side+rear) Below is the code for the form
<%= form_tag('/quotation/tints/generate') do %> <%= label :manufacturer_id, 'Manufacturer' %> <div class="field"> <%= collection_select(:tint, :manufacturer_id, Manufacturer.order(:name), :id, :name, {:prompt => "Select Manufacturer"}) %> </div> Model: <div class="field"> <%= grouped_collection_select(:tint, :model_id, Manufacturer.order(:name), :models, :name, :id, :name, {:prompt => "Select Model"}) %> </div> <%= label :price_front, 'Front Tint' %> <div class="field"> <%= collection_select(:price, :price_front, Price.order(:name), :id, :name, {:prompt => "Select Front Tint"}) %> </div> <%= label :price_rear, 'Size and Back Tint' %> <div class="field"> <%= collection_select(:price, :price_rear, Price.order(:name), :id, :name, {:prompt => "Select Side & Rear Tint"}) %> </div> <div class="form-group"> <%= submit_tag 'Submit' %> </div> <% end %>
When the form is submitted, it should be redirected to /quotation/tints/generate and display the value from the dropdown menu. However, I received an error, saying that Couldn't find Manufacturer with 'id'=. The code that caused the error is shown below
def generate @manufacturers = Manufacturer.find(params[:manufacturer_id]) end Here is the parameter from the debug log
Parameters: {"utf8"=>"✓", "authenticity_token"=>"Pl2bXiRT0AoF4i0h1RCHDbuvaKJNZOkV5ULQHKxDQgZzBWWLJ2mH7ddb9akwgxbloxBIHoVaT3pcwoIGcRufpg==", "tint"=>{"manufacturer_id"=>"7", "model_id"=>"6"}, "price"=>{"price_front"=>"1", "price_rear"=>"2"}, "commit"=>"Submit"}
I can see that the id of each drop down value are shown up correctly in the parameter list. However, I coundn't able to print the value at /quotation/tints/generate nor get the name of the manufacturer or model. Here is routes.rb
get '/quotation/tints' => 'tints#quotation', :as => 'tints_quotation' post '/quotation/tints/generate' => 'tints#generate', :as => 'generate_tints_quotation' Tint.rb class Tint < ApplicationRecord has_many :manufacturers has_many :models belongs_to :manufacturer belongs_to :model validates_uniqueness_of :model_id, :scope => [:manufacturer_id] end
Model.rb class Model < ApplicationRecord belongs_to :manufacturer, :dependent => :destroy validates :name, :presence => true validates_uniqueness_of :name, :scope => [:manufacturer_id] before_save :capitalize_content end
Manufacruter.rb class Manufacturer < ApplicationRecord has_many :models, :dependent => :destroy validates :name, :presence => true, uniqueness: { case_sensitive: false } before_save :capitalize_content end
tints.controller.rb
def quotation render 'quotation' end def generate @manufacturers = Manufacturer.find(params[:manufacturer_id]) end
I have tried multiple ways to define it, but I am still facing the same error. Any help is greatly appreciated. |
| Rails login session and routing Posted: 22 Jul 2016 07:57 AM PDT I am new to Rails and I'm trying to make an app that with login for users, based on this code: https://www.sitepoint.com/rails-userpassword-authentication-from-scratch-part-ii/ However, the app will not let me log in, just clearing the form and showing the login page again. I suspect this has something to do with routing. In the original code, the routes.rb looks like this: match ':controller(/:action(/:id))(.:format)' root :to => 'sessions#login' match "signup", :to => "users#new" match "login", :to => "sessions#login" match "logout", :to => "sessions#logout" match "home", :to => "sessions#home" match "profile", :to => "sessions#profile" match "setting", :to => "sessions#setting"
This gave me a routing error for not using http methods. Modifying my own routes.rb to this: resources :shifts resources :ess_members #resources :sessions get ':controller(/:action(/:id))(.:format)' get 'welcome/start' root 'welcome#start' get "login" => "sessions#home" get "logout" => "sessions#logout" get "home" => "sessions#home" get "profile" => "sessions#profile" get "setting" => "sessions#setting" post '/sessions/login_attempt' => 'sessions#home'
Now I don't get any errors, but when I submit username and password to my form, I just go back to an empty login page. Putting in invalid username/password does not give an error. Is my problem routing? And how do I fix it? My member_controller: class MembersController < ApplicationController before_action :set_member, only: [:show, :edit, :update, :destroy] before_filter :save_login_state, :only => [:new, :create] # GET /members # GET /members.json def index @members = Member.all end # GET /members/1 # GET /members/1.json def show end # GET /members/new def new @member = Member.new end # GET /members/1/edit def edit end # POST /members # POST /members.json def create @member = Member.new(member_params) respond_to do |format| if @member.save format.html { redirect_to @member, notice: 'Ny medlem skapades' } format.json { render :show, status: :created, location: @member } else format.html { render :new } format.json { render json: @member.errors, status: :unprocessable_entity } end end end # PATCH/PUT /members/1 # PATCH/PUT /members/1.json def update respond_to do |format| if @member.update(member_params) format.html { redirect_to @member, notice: 'Medlemmen uppdaterades' } format.json { render :show, status: :ok, location: @member } else format.html { render :edit } format.json { render json: @member.errors, status: :unprocessable_entity } end end end # DELETE /members/1 # DELETE /members/1.json def destroy @member.destroy respond_to do |format| format.html { redirect_to members_url, notice: 'Member was successfully destroyed.' } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_member @member = Member.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def member_params params.require(:member).permit(:memberId, :name, :password, :email, :phone, :boatType) end end
My sessions_controller: class SessionsController < ApplicationController before_filter :authenticate_user, :except => [:index, :login, :login_attempt, :logout] before_filter :save_login_state, :only => [:index, :login, :login_attempt] def home #Home Page end def profile #Profile Page end def setting #Setting Page end def login #Login Form end def login_attempt authorized_user = Member.authenticate(params[:memberId],params[:password]) if authorized_user session[:user_id] = authorized_user.id flash[:notice] = "Wow Welcome again, you logged in as #{authorized_user.memberId}" redirect_to(:action => 'home') else flash[:notice] = "Invalid Username or Password" flash[:color]= "invalid" render "login" end end def logout session[:user_id] = nil redirect_to :action => 'login' end end

| Respond_to throwing redirect error Posted: 22 Jul 2016 07:57 AM PDT I have the following block which takes in two values (example amount but generally more than one). def new # Called when campaign is approved, respond then displays table with campaign details, which when submitted is passed to create @campaign = Campaign.find(params[:campaign_id]) @campaign.each do |value| @applied_campaign = AppliedCampaign.new(:campaign_id => value.id, :start_date => value.start_date||Time.now, :end_date => value.end_date, :active => true) respond_to do |format| format.html # new.html.erb format.json { render json: value } end end end
When i submit the records this block iterates through the different values I believe and then I assume looks to output these values. The problem is that I am getting the following error: Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return".
Can anyone advise why this is the case and how I could generate a view with these two records displayed. Thanks! |
| define_method with super is causing infinite recursion Posted: 22 Jul 2016 07:54 AM PDT I have a form builder subclass: class ErrorHandlingFormBuilder < ActionView::Helpers::FormBuilder
with the following code block: helpers.each do |name| # We don't want to have a label for a hidden field # ERROR: The call to super below is actually calling itself and causing infinite recursion. # How can I get it to call next if name=="hidden_field" define_method name do |field, *args| options = args.detect {|argument| argument.is_a?(Hash)} || {} build_shell(field, options) do super(field,*args) end end end
The super call is calling the method it's encapsulating code block is defining! This is causing infinite recursion and Stack Level Too Deep. What I need is for it to call the method defined by the name variable in the form builder instance itself. I just don't know how to refer to that instance. Even using self.send instead of super still causes the recursion. |

| Rails Facebook Messenger Bot Posted: 22 Jul 2016 07:52 AM PDT This is my first question, so please let me know if I am doing something wrong. I tried to build a simple facebook messenger bot using the 'messenger-ruby' gem (https://github.com/netguru/messenger-ruby). I installed the gem successfully, but I think I don't really get how to send / receive messages. In detail, I followed all the steps in the readme: - get page access token
- create messenger.rb as outlined in the readme
- added the routes exactly as in the readme
- created the messenger_controller.rb as in the readme
- set up webhooks successfully as in the readme
- visited /messenger/subscribe to subscribe
This all worked so far, at https://developers.facebook.com/apps/.../messenger I see a green check under Webooks and see my page under Subscribed pages. I did not do the "App Review for Messenger". Now the problem: I tried to send a standard reply to every incoming message. I put the code from the readme under #components into messenger_controller.rb: # YOUR_APP/app/controllers/messenger_controller.rb class MessengerController < Messenger::MessengerController def webhook #logic here if fb_params.first_entry.callback.message? Messenger::Client.send( Messenger::Request.new( Messenger::Elements::Text.new(text: 'some text'), fb_params.first_entry.sender_id ) ) end render nothing: true, status: 200 end end
But when one of the page admins sends a message to the page, nothing happens. I looked in the logs, but don't see the POST request I'd expect. When use my browser to visit https:/.../messenger/webhook, I see "Invalid verify token", and in the logs it shows the following: Started GET "/messenger/webhook" for xxx.xxx.xxx.xxx at 2016-07-22 14:39:52 +0000 Cannot render console from xxx.xxx.xxx.xxx! Allowed networks: 127.0.0.1, ::1, 127.0.0.0/127.255.255.255 Processing by Messenger::MessengerController#validate as HTML Completed 200 OK in 10ms (Views: 0.3ms | ActiveRecord: 0.0ms)
I guess that's ok, but I am not sure. I'm sure I probably made a simple mistake, but I was reading the docs all day and couldn't find a solution. I'm not even sure what the problem is, as I'd expect to find the POST request in the logs... Any help would really be appreciated. And please let me know how I could improve my question. |
| How to select values in a multiselector based on the selected values of another multiselector Posted: 22 Jul 2016 08:04 AM PDT I have two multiselectors as follows, the first one using the Chosen plugin: <%= select_tag :provinces, options_for_select(DataHelper::all_provinces_captions.zip(DataHelper::all_provinces_ids)), {:multiple => true, class: 'chosen-select chzn-select', :data => {:placeholder => 'Filter Provinces/States'}, :style => "width: 100%; height: 100px;"}%> <%= f.select :province_ids, (DataHelper::all_provinces_captions.zip(DataHelper::all_provinces_ids)), { include_blank: true }, {multiple: true, data: {placeholder: 'Filter Provinces/States'} } %>
I want to make the selected values in the :provinces selector, the same as the selected value of the :province_ids selector, on page load. Something similar to this: $(document).ready(function() { $("#education_plan_province_ids option:selected").each(function () { $("#provinces option[value='"this"']").prop('selected', true); }); });
Except, of course, that doesn't work :D |

| How to pass GET parameters to next controller action in Ruby on Rails? Posted: 22 Jul 2016 07:15 AM PDT In my Rails 4.2 app I have an index action that lists all the user's invoices, filtered by search parameters in the URL: class InvoicesController < ApplicationController def index @invoices = current_user.invoices.search(params) respond_to do |format| format.html do @title = "Invoices" ... end format.csv do headers['Content-Disposition'] = "attachment; filename=\"#{invoices_filename}.csv\"" end format.xls do headers['Content-Disposition'] = "attachment; filename=\"#{invoices_filename}.xls\"" end end end ... end
This works nicely. The user can filter his invoices by various parameters and the listed invoices adjust accordingly. The problems start when the user wants to download these exact invoices in XLS or CSV format. I have a link for that on index.html.erb: <%= link_to "Download invoices", invoices_path(:format => "xls") %>
However, it downloads all the invoices, not just the ones the user filtered out previously. Is there a way to pass the search params on to the next action or maybe a more elegant solution all together? Thanks for any help. |

| How to config Sails/Node App with Apache/Passenger Posted: 22 Jul 2016 06:27 AM PDT First of all, this is for dev purposes only. On my Mac I've got Apache running with Passenger which serve many Rails/Ruby App. An example of an Apach config for Rails would be: <VirtualHost *:80> ServerName example.lc ServerAlias www.example.lc RailsEnv development PassengerFriendlyErrorPages on PassengerRuby /Users/user/.rvm/gems/ruby-2.2.3/wrappers/ruby DocumentRoot "/path/to/my/app/public" ErrorLog "/path/to/my/app/log" CustomLog "/path/to/my/app/log" common ServerAdmin example@example.com <Directory "/path/to/my/app/public"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost>
And on my host file I'd have 192.168.0.1 www.example.lc and that would work fine. I'd like to do the same for a Node App based off Sails. I've tried the following: <VirtualHost *:80> ServerName example.lc ServerAlias www.example.lc NODE_ENV development PassengerFriendlyErrorPages on PassengerNodejs /usr/bin/node DocumentRoot "/path/to/my/app/public" ErrorLog "/path/to/my/app/log" CustomLog "path/to/my/app/log" common ServerAdmin me@example.com <Directory "/path/to/my/app/public"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost>
But that doesn't work. Nor it shows any error on the log file. Any ideas? Please note that I've also tried PassengerNodejs /Users/user/.nvm/versions/node/v4.4.7/bin/node which is the path I get when I do which node. That didn't work either. |

| Rails assets compiling issue on AWS elasticbeanstalk Posted: 22 Jul 2016 06:21 AM PDT Facing an odd issue with Rails assets, and I'm not sure where the problem even lies: I deployed my Angular Rails app onto AWS elasticbeanstalk, and the assets compiled without throwing any errors. Then when I went to the website it turns out that the application.js and application.css files were simply two lines of an angular template: <div class="angular-flash-container" flash-message="5000"></div> <div ui-view></div>
All other js and css assets are not compiled or included. All compiled images were turned a html file I had placed in "public/500.html". They were all committed as .jpg and .png images, but when they are compiled by elastic beanstalk and served their url says <link rel="apple-touch-icon" type="image/png" href="https://cdn.site.net/images/apple-icon-57x57.png" sizes="57x57" />
but their content is a html file rather than an image. I tried rake assets:precompile on my localmachine and everything compiles as they should. This problem only occurs on elastic beanstalk and cannot be reproduced locally. I suspect it's a problem with sprockets, but I would appreciate any pointers in how to debug this.

| Deleting a comment in belongs_to and has_many association Posted: 22 Jul 2016 06:35 AM PDT I am following Getting stated with rails simple Blog app. In the last part while deleting a comment they have used def destroy @article = Article.find(params[:article_id]) @comment = @article.comments.find(params[:id]) @comment.destroy redirect_to article_path(@article) end
My question is why do they want to delete comment like that @comment = @article.comments.find(params[:id])
when @comment = Comment.find(params[:id])
both returns the same @comment object. since id will be unique through out comments. why they want to take extra step in finding article. May be because first we need to check if comment belong to that article or not before deleting? or is that rails way to delete when such kind of association is setup |

| Disable mongoid belongs_to validation Posted: 22 Jul 2016 06:14 AM PDT A have two mongoid models with a simple has_many/belongs_to relationship between them. class Lot include Mongoid::Document has_many :journal_items end class JournalItem include Mongoid::Document belongs_to :lot end
The issue is that I can't create a JournalItem without a Lot as it seems that mongoid adds a non-null validation on JournalItem.lot_id for whatever reason. JournalItem.create! # raises validation error "Lot can't be blank"
How can I disable it? I use the mongoid master with Rails 5. |
| OmniAuth::Strategies::OAuth2::CallbackError CSRF detected on going back from browser after successful login. Doorkeeper, devise, omniauth-oauth2 Posted: 22 Jul 2016 06:50 AM PDT I've build an OAuth2 provider using the doorkeeper engine with devise. On my client app I'm using a custom omniauth-oauth2 -v 1.3.1 strategy. Everything works well, but after I sign in if I hit the back button on the browser I get  I dug into the omniauth-oath2 code and it appears that there are two methods that I think are closely related to this problem, one that creates the session["omniauth.state"] from the url params: def authorize_params options.authorize_params[:state] = SecureRandom.hex(24) params = options.authorize_params.merge(options_for("authorize")) if OmniAuth.config.test_mode @env ||= {} @env["rack.session"] ||= {} end session["omniauth.state"] = params[:state] params end
and one that checks this and deletes this from the session on the callback process: def callback_phase # rubocop:disable AbcSize, CyclomaticComplexity, MethodLength, PerceivedComplexity error = request.params["error_reason"] || request.params["error"] if error fail!(error, CallbackError.new(request.params["error"], request.params["error_description"] || request.params["error_reason"], request.params["error_uri"])) elsif !options.provider_ignores_state && (request.params["state"].to_s.empty? || request.params["state"] != session.delete("omniauth.state")) fail!(:csrf_detected, CallbackError.new(:csrf_detected, "CSRF detected")) else self.access_token = build_access_token self.access_token = access_token.refresh! if access_token.expired? super end rescue ::OAuth2::Error, CallbackError => e fail!(:invalid_credentials, e) rescue ::Timeout::Error, ::Errno::ETIMEDOUT => e fail!(:timeout, e) rescue ::SocketError => e fail!(:failed_to_connect, e) end
It appears that somehow the first method is not called on going back from the browser. Does someone had the same problem and is there a solution to this problem without setting the :provider_ignores_state to true. Do I need to set something on the provider, I really don't get it, plus I can't seem to find this problem anywhere on the web and I highly doubt it I'm the first one that recognizes it, but I may be the first one that can't find a reasonable solution without affecting security. |
| Convert coffeescript function to javscript Posted: 22 Jul 2016 05:27 AM PDT I am following this railscast https://www.youtube.com/watch?v=ltoPZEzmtJA but I don't use coffeescript. I am trying to convert the coffeescript to javascript but I'm running into a problem. coffeescript jQuery -> new AvatarCropper() class AvatarCropper constructor: -> $('#cropbox').Jcrop aspectRatio: 1 setSelect: [0, 0, 600, 600] onSelect: @update onChange: @update update: (coords) => $("#crop_x").val coords.x $("#crop_y").val coords.y $("#crop_w").val coords.w $("#crop_h").val coords.h
js.erb file $(document).ready(function() { $('.crop-image').on('click', function () { $('#cropbox').Jcrop({ aspectRatio: 1, setSelect: [0, 0, 100, 100], onSelect: update, onChange: update }) }); update: (function(_this) { return function(coords) { $('.user').val(coords.x); $('.user').val(coords.y); $('.user').val(coords.w); return $('.user').val(coords.h); }; })(this) });
I didn't understand why he decided to make a class and thought it would be more complicated to convert the whole thing. The trouble I'm having is the update function. I just plugged his coffee script for the update function into a converter and used the output. This is causing an error saying update is not defined. Where am I going wrong? Also bonus question: what's the point of him making a class here? Thanks! |
| Solr Highlighting version 1.8.24 Posted: 22 Jul 2016 05:05 AM PDT I am quite new in Solr. I want to highlight the section where Solr finds my query. I am able to search everything. In my model I did these things: searchable do text :name, :as => :name_textf, :stored => true do |model| if not model.titles == nil model.titles.first else model.name end end text :bodies, :stored => true text :titles, :stored => true
Then in my controller I searched like this search = Sunspot.search(TkAnalysis) do fulltext query do phrase_fields(tkanalysisPhraseFields(language)) fields(tkanalysisPhraseFields(language)) minimum_match [(query.split(/\W+/).count / 3.0).round, 1].max highlight :titles, :name, :bodies end with :organization, $organization["sub_domain_name"] end
I also tried :highlight => true and :max_snippets => 3, :fragment_size => 0 also didn't help Then for my query I don't find any highlights whatsoever even when the query is in the name

| Issues with dropdown select_tag placeholder with prompt Posted: 22 Jul 2016 06:11 AM PDT I'm having an issue with setting a placeholder within dropdown selection form using the rails select_tag helper. Using the prompt option a placeholder exists, but this method produces a dead duplicate value in the dropdown that you can't click: 
Here is my code: @posts = Post.all @categories = Post.uniq.pluck(:category) @prompt = "Select Category" if params[:category] @posts = Post.where(category: params[:category]) @prompt = params[:category] end <%= form_tag(h_path, :method => "get") do %> <%= select_tag 'category', options_for_select(@categories), {onchange: "this.form.submit();", prompt: @prompt} %> <% end %>
Any ideas or suggestions regarding making a placeholder value work nicely in this context would be greatly appreciated. By nicely I mean something like the category dropdown select example on this page: http://www.joeabercrombie.com/category/audiobooks/ |
| How to implement Single Sign Out for Multiple Applications with Devise in Rails Posted: 22 Jul 2016 06:04 AM PDT There is a tutorial here on Single Sign On (SSO) for Multiple Applications with Devise, OmniAuth and Custom OAuth2 Implementation in Rails. single Sign-on works but signing out only clears the session on current application as you can see from the destroy action below. def destroy session[:user_id] = nil flash[:notice] = 'You have successfully signed out!' redirect_to "#{CUSTOM_PROVIDER_URL}/users/sign_out" end
the redirect_to method doesn't work because each app make a copy the session. How can I extend this action to support single sign-out? |
