| Concatenate bytes - Writing file to FTP folder as chunks Posted: 15 Nov 2016 07:41 AM PST I'm writing an Rails app which could upload files to storage. Big files are splitted into chunks from client (with JS) and upload parts to server. As in development, I could simply open existed file and write following bytes into that. (I'm using CarrierWave gem) File.open(@up_file.link.path, "ab") do |f| f.write(up_file_params[:link].read) end # This code worked when I upload to '/public' folder in development
However, now I want to use a FTP server to storage files. But I can't Concatenate new bytes with existed bytes. def get_ftp_connection # create a new FTP connection ftp = Net::FTP.new ftp.connect(ENV['ftp_host'], ENV['ftp_port']) begin ftp.passive = ENV['ftp_passive'] ftp.login(ENV['ftp_user'], ENV['ftp_passwd']) yield ftp ensure ftp.quit end end ..... def create ..... get_ftp_connection @up_file do |ftp| full_path = ::File.dirname "#{ENV['ftp_folder']}/#{@up_file.link.path}" base_name = File.basename(@up_file.link.to_s) ftp.chdir(full_path) ftp.putbinaryfile(up_file_params[:link].read, base_name) end end
I got ArgumentError (string contains null byte): at putbinaryfile... , any help :( |
| Prepopulate rails form_for email_field with email address Posted: 15 Nov 2016 07:16 AM PST I have a simple email field that I want to pre-populate with the user's email when they hit the login page (assuming they followed a link there and we can identify who they are). I have: <%= f.email_field :email, autofocus: @contact.email.blank?, class: "form-control" %>
I've tried doing: <%= f.email_field(@contact, @contact.email) :email, autofocus: @contact.email.blank?, class: "form-control" %> <%= f.email_field(@contact.email) :email, autofocus: @contact.email.blank?, class: "form-control" %>
And also: <%= f.email_field :email, autofocus: @contact.email.blank?, class: "form-control", value: @contact.email %>
But nothing seems to work. I'd like to avoid changing the field type to text if possible. |
| Authorization settings using pundit gem rails Posted: 15 Nov 2016 07:03 AM PST I'm new at rails so bear with me pls. My problem is so specific. I'm creating a User blog, where they could put any posts. So Users has a blogs, and blogs has posts. So when user create a blog, all posts in his blog should be written by him. Other users can't write not on their blogs. post_controller.rb class PostsController < ApplicationController before_action :authenticate_user! before_action :authorize_user!, only: [:edit, :update, :destroy] expose :blog expose :post def show end def new end def edit end def create post.user = current_user post.save respond_with post, location: user_blog_path(post.blog.user, post.blog) end def update post.update(post_params) respond_with post, location: user_blog_path(post.blog.user, post.blog) end def destroy post.destroy respond_with post, location: user_blog_path(post.blog.user, post.blog) end private def authorize_user! authorize(post, :authorized?) end def post_params params.require(:post).permit(:title, :content, :user_id, :blog_id) end end
Here i'm using pundit to authorize user, when they update or destroy posts (users can update or destroy only their own posts) and it works perfectly. views/posts/new .row .columns h2 = title("New post") .row .medium-5.columns = simple_form_for post do |f| = f.error_notification .form-inputs = f.input :title = f.input :content = f.hidden_field :blog_id, value: blog.id .form-actions = f.button :submit
Here i'm using the hidden form to set the blog_id which I take from params. Http link looks like http://localhost:3000/posts/new?blog_id=6. The problem is that each user can copy this link to create the post( and they are not the blog owners). post_policy.rb class PostPolicy < ApplicationPolicy def authorized? record.user == user end end
How should I check the blog's owner before post creating? Maybe I have a wrong way to create posts like this(using hidden form). Link to create new post = link_to 'New Post', new_post_path(blog_id: blog.id)

| Filterrific Not Passing Multiple Parameters to Scope Posted: 15 Nov 2016 06:49 AM PST I have a filterrific scope that accepts multiple parameters. The scope appears to be functioning correctly (I can call Marketplace::Lot.with_price({}) in the console and it returns the correct results), but filterrific isn't passing any data to it when I enter information on the form. Here is my filterrific declaration in the model filterrific( default_filter_params: { sorted_by: 'time_remaining_asc' }, available_filters: [ :with_price, :sorted_by, :lots_with_item_type, :search_query ] )
Here is what my controller looks like: @filterrific = initialize_filterrific( Marketplace::Lot, params[:filterrific], select_options: { sorted_by: Marketplace::Lot.options_for_sorted_by, item_types: Marketplace::Lot.options_for_item_types }, persistence_id: 'marketplace_key', ) or return @lots = @filterrific.find.paginate(page: params[:page], per_page: 20)
and my view <%= f.fields_for :with_price, OpenStruct.new(@filterrific.with_price) do |with_price_fields| %> <div class="marketseach__shards shards"> <%= with_price_fields.text_field :shards_min, class: 'marketplace__value input', placeholder: 'Low Value' %> - <%= with_price_fields.text_field :shards_max, class: 'marketplace__value input', placeholder: 'High Value' %> </div> <span class="marketsearch__text">or</span> <div class="marketsearch__gems gems"> <%= with_price_fields.text_field :gems_min, class: 'marketplace__value input', placeholder: 'Low Value' %> - <%= with_price_fields.text_field :gems_max, class: 'marketplace__value input', placeholder: 'High Value' %> </div> <% end %>
When I submit the form, the price fields appear in the params hash "filterrific"=> { "search_query"=>"Programming", "lots_with_item_type"=>"", "with_price"=>{"shards_min"=>"200", "shards_max"=>"", "gems_min"=>"", "gems_max"=>""}, "sorted_by"=>"alpha_asc" },
However, it never gets to the scope (I have a binding.pry in the scope that never gets hit). I should note that all other scopes are working correctly. I'm sure I'm missing something obvious but I can't find it for the life of me. |
| Ruby on Rails - contact form is not working Posted: 15 Nov 2016 06:51 AM PST I followed this website to do the contact form in my rails application. I am using a blank bootstrap template inside the rails application. https://rubyonrailshelp.wordpress.com/2014/01/08/rails-4-simple-form-and-mail-form-to-make-contact-form/ The only difference that I made is that in the contact.rb I added my email class Contact < MailForm::Base attribute :name, :validate => true attribute :email, :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w] {2,})\z/i attribute :message attribute :nickname, :captcha => true def headers { :subject => "My Contact Form", :to => "here I added my email", :from => %("#{name}" <#{email}>) } end end

| Handling Non Logged In user - Rails 4 - Devise Posted: 15 Nov 2016 06:45 AM PST I have an agent model and an agent_review model. I have some controller logic that will save an agent's ID when that user is logged in. However, when a non-logged in user tries to leave a review I get a NoMethodError: undefined method id for nil:NilClass. I have tried rescue and couldn't manage to get that to work. The hope is to be able to have the non-logged in agent_id return nil and then any agent with an ID of Nil default to Guest in the view. Unless there is a better way to accomplish this goal. agent_reviews_controller: def create @agent_review = AgentReview.new(agent_review_params) @agent_review.reviewer_id = current_agent.id respond_to do |format| if @agent_review.save AgentReviewMailer.agent_review_message(@agent_review, @agent).deliver_later format.html { redirect_to agent_agent_reviews_path, notice: 'Agent review was successfully created.' } format.json { render :show, status: :created, location: @agent_agent_review } else format.html { render :new } format.json { render json: @agent_review.errors, status: :unprocessable_entity } end end end

| administrate ruby gem: customizing the resource name in the index vs show pages Posted: 15 Nov 2016 06:35 AM PST By overriding the display_resource() method in an administrate dashboard, it is possible to customize what gets shown in both the index and collection pages (see this). But in many cases, one would like to see a shorter version of the resource name in a table column, than at the top of a "show" page. For example, initials vs. full name. How would you accomplish that with this gem? |

| Linking members through referrals - Rails Posted: 15 Nov 2016 06:54 AM PST I have used Devise to create a referral tracking system similar to this article. I have added 2 columns to the Members table: refer:string and referral_code:string. When a user registers a unique string is created for them and saved in refer to be used later as their referral code, when they register and are using a referral link, the referer's refer code gets saved to the refered member's referral_code field. The problem that I have is linking the referer and referral_code, so that the person that referred can see a list of all the members that signed up with their referral_code. I need assistance with the query that I can run to link the 2. Any assistance will be greatly appreciated. |

| Stub Net::HTTPCreated response in rspec Posted: 15 Nov 2016 05:51 AM PST I am a uploading image file on another site, and they have provided upload API for the same. File upload process is divided into 2 parts - Create image Id (POST)
- Upload image (PUT)
When I create an image id, it returns id in the response. For this, I have added following methods that achieves this functionality. def create_image_id response = create_via_api(data) # we get response in the following format # #<Net::HTTPCreated 201 Created readbody=true> find_id_from_response(response) end def create_via_api(data) access_token.post(IMAGE_CREATE_URL, data, 'Accept' => ACCEPT_HEADER) end # We are getting id from the response headers in the following format # location: SITE_URL/imageResources/5ac2acb2 def find_id_from_response(response) id = response.to_hash['location'].first return unless id id.split('/').last.chomp end
Now I have to write the test case for the create_image_id method. As for test case communicate with 3rd party API is not a good practice. So I am stubbing the POST response say, allow(Image).to receive(:find_id_from_response).and_return('1234')
so it will always return id as 123 so that I can write test case as expect(image. create_image_id).to eq 1234
As you can see find_id_from_response take parameter (#). Note: here is the header of the response [36] pry(#)> response.to_hash { "content-type"=>["text/plain"], "x-frame-options"=>["SAMEORIGIN"], "location"=>["www.example.com/imageResources/cd87b8ef"], "vary"=>["Accept-Encoding"], "cache-control"=>["max-age=0, no-cache"], "pragma"=>["no-cache"], "date"=>["Tue, 15 Nov 2016 12:01:56 GMT"], "connection"=>["close"] }
I tried with following [28] pry()> Net::HTTPCreated.new(1, 201, 'Created') => #<Net::HTTPCreated 201 Created readbody=false> [29] pry()> a = Net::HTTPCreated.new(1, 201, 'Created') => #<Net::HTTPCreated 201 Created readbody=false> [30] pry()>)> a.to_hash => {}
it is returning empty hash. So how can I stub the response of create_via_api? Let me know anything you need. |

The booking system aims to cater for both free and paid bookings. The free bookings routes go to the show page as required. The above error happens when making a paid booking (payments via Stripe). This is the relevant controller code - bookings_controller.rb def new @event = Event.find(params[:event_id]) @booking = @event.bookings.new(quantity: params[:quantity]) # which person is booking the event? @booking.user = current_user end def create @event = Event.find(params[:event_id]) @booking = @event.bookings.new(booking_params) @booking.user = current_user if @booking.paid_booking flash[:success] = "Your place on our event has been booked" @booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase) redirect_to event_booking_path(@event) else flash[:error] = "Booking unsuccessful" render "new" end end def free_booking if @booking.free_booking @booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase) redirect_to event_booking_path(@event) else flash[:error] = "Booking unsuccessful" render "new" end end def show @event = Event.find(params[:event_id]) @booking = @event.bookings.new @booking = Booking.find_by(params[:booking_number]) end def update puts params @event = Event.find(params[:event_id]) @booking = @event.bookings.new(booking_params) if @booking.save redirect_to event_booking_path , notice: "Booking was successfully updated!" else render 'new' end end private def booking_params params.require(:booking).permit(:stripe_token, :booking_number, :quantity, :event_id, :stripe_charge_id, :total_amount) end
The error message focuses on this line in the @booking.paid_booking method - redirect_to event_booking_path(@event)
This is odd as its the same route used for free_booking which routes through to the show page with no errors. This is my view forms for free & paid bookings - <% if @booking.free_booking %> <div class="col-md-6 col-md-offset-3" id="eventshow"> <div class="row"> <div class="panel panel-default"> <div class="panel-heading"> <h2>Confirm Your Booking</h2> </div> <%= simple_form_for [@event, @booking], id: "new_booking" do |form| %> <% if @booking.errors.any? %> <h2><%= pluralize(@booking.errors.count, "error") %> prevented this Booking from saving:</h2> <ul> <% @booking.errors.full_messages.each do |message| %> <li><%= message %></li> <% end %> </ul> <% end %> <div class="form-group"> <p>Please confirm the number of spaces you wish to reserve for this event.</p> <%= form.input :quantity, class: "form-control" %> </div> <p> This is a free event. No payment is required.</p> <div class="panel-footer"> <%= form.submit :submit, label: 'Confirm Booking', class: "btn btn-primary" %> <% end %> </div> <% else %> <div class="col-md-6 col-md-offset-3" id="eventshow"> <div class="row"> <div class="panel panel-default"> <div class="panel-heading"> <h2>Confirm Your Booking</h2> </div> <%= simple_form_for [@event, @booking], id: "new_booking" do |form| %> <div class="calculate-total"> <p> Confirm number of spaces you wish to book here: <input type="number" placeholder="1" name="booking[quantity]" min="1" value="1" class="num-spaces"> </p> <p> Total Amount £<span class="total" data-unit-cost="<%= @event.price %>">0</span> </p> </div> <span class="payment-errors"></span> <div class="form-row"> <label> <span>Card Number</span> <input type="text" size="20" data-stripe="number"/> </label> </div> <div class="form-row"> <label> <span>CVC</span> <input type="text" size="4" data-stripe="cvc"/> </label> </div> <div class="form-row"> <label> <span>Expiration (MM/YYYY)</span> <input type="text" size="2" data-stripe="exp-month"/> </label> <span> / </span> <input type="text" size="4" data-stripe="exp-year"/> </div> </div> <div class="panel-footer"> <%= form.button :submit %> </div> <% end %> <% end %> </div> </div> </div>
This is the routes file - routes.rb Rails.application.routes.draw do devise_for :users, :controllers => { omniauth_callbacks: "omniauth_callbacks", registrations: "registrations" } resources :users # the above resource draws out routes for user profiles resources :events do resources :comments resources :bookings end root 'events#index' end
And routes -  I'm sure this is something quite obvious put I'm afraid I can't spot it. |
| Build vanity urls with variables stored in a different table from the model Posted: 15 Nov 2016 05:16 AM PST I am trying to build vanity urls with FriendlyId gem for a specific model Teacher to display www.mysite.com/teachers/{first_name}-{last_name}
instead of wwww.mysite.com/teachers/{id}
The problem that I encounter is that the information on the {first_name} / {last_name} is stored in the table Contact accessible through User and not in Teacher's one. The relation between the tables is as follows: - Teacher belongs_to :user - User has_one :contact
I added in my Teacher model: extend FriendlyId friendly_id :full_name_to_url, use: :slugged
So FriendlyId calls the method full_name_to_url to create the slug: def full_name_to_url "#{self.user.contact.first_name.downcase.gsub(" ","-")}-#{self.user.contact.last_name.downcase.gsub(" ","-")}" end
I received the following message when trying to apply and save all the changes to the already existing records: Teacher.find_each(&:save) NoMethodError: undefined method `contact' for nil:NilClass
I guess there is something wrong with my method? |

| Retrieving data from two Rails model Posted: 15 Nov 2016 05:26 AM PST I have an Activation model that belongs to User. I'm trying to display information of the activation that the user has submitted in the views, but I'm not sure how to do this. For example, class Activation < ApplicationRecord belongs_to :user default_scope -> { order(created_at: :desc) } validates :user_id, presence: true validates :dealer_store, presence: true, length: { maximum: 50 } validates :customer_name, presence: true, length: { maximum: 50 } validates :customer_phone_number, presence: false, length: { maximum: 10 } class User < ApplicationRecord has_many :activations validates :name, presence: true, length: { maximum: 50 }
I am able to get data from the user of the activations with the user id like so <%= activation.user.dealer_store %>
How would I obtain the customer_phone_number of the activation of the user? I seem to be missing something You may find it here https://bitbucket.org/QuriouslyStrong/sample_app |
| "Stack level too deep" when we try to access deleted object Posted: 15 Nov 2016 05:34 AM PST Current env: Rails 4.2 Ruby 2.1.4 DB: mongodb 4 My current project is a multi-tenant architecture and hence all models defined :belongs_to a main object lets say "account". Whenever I delete any child model(say "library"), if I try to access(either delete/show operation) it immediately, I am getting the below exception consistently: Stack level too deep with exception raised => actionpack (4.2.0) lib/action_dispatch/middleware/reloader.rb:79 Basically here is model structure: class Account . . has_many :libraries, dependent: :delete end class Library . . belongs_to :account end
Using mongoid as DB. Any suggestions are Note: all models are fetched using "account_id" relation along with the object id. Also once i kill the serve and restart it, i am getting the proper "Document not found" for the deleted object. EDIT: Delete operation: def destroy_library self.destroy end
Tried removing "dependent: delete" as suggested by other threads but no luck. |

| google analytics embed api with turbolinks in rails Posted: 15 Nov 2016 05:02 AM PST I am trying to implement the google analytics embed api using javascript code provided by google to my rails app and taking help from this link -> https://ga-dev-tools.appspot.com/embed-api/. Now I dont know how to run these scripts on every page change because these javascripts listens to the page load event and rails uses turbolinks that actually doesn't loads the page it swaps only body and title. Now the problem is that javascript doesn't respond as it does not know that page has been changed. Please help me out. <script> (function (w, d, s, g, js, fs) { g = w.gapi || (w.gapi = {}); g.analytics = { q: [], ready: function (f) { this.q.push(f); } }; js = d.createElement(s); fs = d.getElementsByTagName(s)[0]; js.src = 'https://apis.google.com/js/platform.js'; fs.parentNode.insertBefore(js, fs); js.onload = function () { g.load('analytics'); }; }(window, document, 'script')); </script> <div id="embed-api-auth-container"></div> <div id="chart-container"></div> <div id="view-selector-container"></div> <script> gapi.analytics.ready(function () { /** * Authorize the user immediately if the user has already granted access. * If no access has been created, render an authorize button inside the * element with the ID "embed-api-auth-container". */ gapi.analytics.auth.authorize({ container: 'embed-api-auth-container', clientid: '7xxxxxxxxxx-mtgoounogp8pu2brjsi1mfpbrohtcppd.apps.googleusercontent.com' }); /** * Create a new ViewSelector instance to be rendered inside of an * element with the id "view-selector-container". */ var viewSelector = new gapi.analytics.ViewSelector({ container: 'view-selector-container' }); // Render the view selector to the page. viewSelector.execute(); /** * Create a new DataChart instance with the given query parameters * and Google chart options. It will be rendered inside an element * with the id "chart-container". */ var dataChart = new gapi.analytics.googleCharts.DataChart({ reportType: 'ga', query: { metrics: 'ga:sessions', dimensions: 'ga:date', 'start-date': '30daysAgo', 'end-date': 'yesterday' }, chart: { container: 'chart-container', type: 'LINE', options: { width: '100%' } } }); /** * Render the dataChart on the page whenever a new view is selected. */ viewSelector.on('change', function (ids) { dataChart.set({ query: { ids: ids } }).execute(); }); }); </script>
for the very first time my code is running properly but if i switch to another link or come back to the same page after visiting another page via turbolinks the javascript doesn't run. Please help. Thanks |
