Rails 5 - ENV DATABASE_URL - specify encoding and collation Posted: 06 Oct 2016 08:00 AM PDT Our database.yml is added to .gitignore so devs can customize local environments and we plan to use ENV['DATABASE_URL'] for production servers. For default setup, this works. However, we need to configure encoding and collation to utf8mb4. encoding: utf8mb4 collation: utf8mb4_unicode_ci I tried padding it to query parameters, like the ?pool=5 example in the docs, but it doesn't seem to work. DATABASE_URL=mysql2://user:passwd@host:port/dbname?encoding=utf8mb4&collation=utf8mb4_unicode_ci The tables created are still using the default encoding/collation so I assume the parameters doesn't work. Is there any way I could configure this by any other methods? Encoding and collation is the same for all environments. Requirement is that dev environment can have a file with a config whereas prod should have no special file added, it should only use ENV variables. Maybe add this to one of the files inside config dir like application.rb or other files? Thanks in advance. PS: I'm new to Rails and Ruby (1 week) since I'm coming from PHP/Python.

Rails.application.secrets.KEY_NAME returns Uninitiated Constant (NameError) Posted: 06 Oct 2016 07:56 AM PDT I am trying to access an API and cannot get the key in secrets.yml to authorize. I have gone into rails console and confirmed that Rails.application.secrets.KEY_NAME returns the correct key. But it isn't working when I run the .rb file. How can I get it to work the way it's supposed to?

Add class to image_tag in Rails with IF statement Posted: 06 Oct 2016 07:52 AM PDT I have a image tag setup for a blog that if an image has been attached to the blog then display the image. <%= image_tag blog.image_url(:thumb) if blog.image? %> I am trying to add a class to this image tag so that I can use CSS to edit it. I have tried a few different ways to add the class but none seem to work. <%= image_tag blog.image_url(:thumb) if blog.image?, :class => "img" %> or <%= image_tag (blog.image_url(:thumb), :class => "img") if blog.image? %> or <%= image_tag (blog.image_url(:thumb) if blog.image?), :class => "img" %> does anyone know how to add a class to this type of statement?

Rails Cart deleting itself Posted: 06 Oct 2016 07:44 AM PDT I'm having an issue with my cart in an e-commerce app. When the user signs in and adds an item to Cart, the item does not add immediately. The user has to go back and add it a second time before it goes into the cart. I've looked at the logs and i've been able to find that the issue occurs when a user has previously purchased something and is signing to purchase at a later time.The next time they log in to purchase another item, is when it occurs. The system tries to delete the old cart and create a new one but what ultimately happens is, the new cart shows up empty on first attempt. Is there a way to avoid this? Any help would be appreciated. Thanks in advance! def show if current_user if current_user.cart.purchased_at session[:cart_id] = nil else @cart = current_user.cart ||= Cart.find_by(session[:cart_id]) end end if session[:cart_id].nil? current_user.cart = Cart.create!(user_id: params[:id]) session[:cart_id] = current_user.cart.id end @cart = current_user.cart end

Most recent record form Elasticsearch Rails based on Multiple indices Posted: 06 Oct 2016 07:48 AM PDT I have two models in my Rails application: Share and Rent. I'm starting to use ElasticSearch in my application and wanted a way to bring the models rent and share most recent. I tried the following: @response = Elasticsearch::Model.search query: { "indices": { "indices": [ "shares", "rents" ], "query": { "multi_match": { "query": "Apartament", "fields": [ "tipe"] } }, "no_match_query": { "term": { "": "" } }, } } But I do not know how to bring the most recent based on create_at field.

batch jpg images in string not all written to file with ruby file open write barby gem Posted: 06 Oct 2016 07:41 AM PDT I am using barby gem to generate barcodes. I am doing it a batch at a time and then save all of them in a file to be viewed by the user. I am not trying to print one at a time. def generate_barcode number_of_instances = params[:times].to_i value = 12.times.map{rand(10)}.join barcodes = 10.times.collect { Barby::EAN13.new(value) } #collects ten barcodes in an array processed_barcodes = barcodes.map {|barcode| barcode.to_jpg_2(:height => 60)} #returns an array and each element is a string of jpeg file File.open('code.jpg', 'wb') do |f| processed_barcodes.each {|barcode| f.write(barcode)} #stuck here #f.puts(processed_barcodes) #tried this end send_file('code.jpg', :type => 'image/jpeg', :disposition => 'inline' ) end the view <%= image_tag(url_for({:controller => 'business_partners', :action => 'generate_barcode', :format => 'jpg' })) %> processed_barcodes.count came back with 10. My code.jpg got processed but I only have 1 image.

How to assign two foreign keys to the same parent table with rails migration? [duplicate] Posted: 06 Oct 2016 07:33 AM PDT This question already has an answer here: How do I add migration with multiple references to the same model in one table? Ruby/Rails 1 answer I have User model and trying to create Contact model with foreign keys having such code in migration: def change create_table :contacts do |t| ... t.reference :user, index:true, foreign_key: { column_name: :created_by } t.reference :user, index:true, foreign_key: { column_name: assigned_to } But there is only one column created in schema.rb: t.integer "user_id Questions: What's wrong with my code? Do I really need to assign foreign key in migration through t.references? Can I simply create t.integer fields with right names and indexes and set foreign_key option in contact.rb?

Rails - How to ensure a parameter is updated correctly Posted: 06 Oct 2016 07:48 AM PDT I'm building an events app using rails. For the payment process I'm using Stripe and some javascript to update the amounts. I want the user to be able to specify the number of spaces (quantity) they wish to pay for and for this to update the total amount they then need to pay. The code I'm using is updating the text for the total amount payable but it's not updating the server so every time I do a test payment only one single amount is collected. So, if an event costs £10 per space and I try and input, say, 4 spaces (£40) when I do a test only £10 has been collected by Stripe. I need to ensure the quantity parameter is being passed correctly. This is my booking page code - new.booking.html.erb <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" 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> <script type="text/javascript"> $('.calculate-total input').on('keyup change', calculateBookingPrice); function calculateBookingPrice() { var unitCost = parseFloat($('.calculate-total .total').data('unit-cost')), numSpaces = parseInt($('.calculate-total .num-spaces').val()), total = (numSpaces * unitCost).toFixed(2); if (isNaN(total)) { total = 0; } $('.calculate-total span.total').text(total); } $(document).ready(calculateBookingPrice) </script> This is my controller code with the quantity param - bookings_controller.rb 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(quantity: params[:quantity]) # which person is booking the event? @booking.user = current_user #@total_amount = @event.price * @booking.quantity end def create # actually process the booking @event = Event.find(params[:event_id]) @booking = @event.bookings.new(booking_params) @booking.user = current_user if @booking.reserve flash[:success] = "Your place on our event has been booked" redirect_to event_path(@event) else flash[:error] = "Booking unsuccessful" render "new" end end How do I amend this so the total amount is correctly collected?

OpenSSL::PKey::RSAError (Neither PUB key nor PRIV key: nested asn1 error) while using Grocer gem on RoR app Posted: 06 Oct 2016 07:23 AM PDT I know there are a lot of questions on this scenario but I've tried every solution and I am still stuck. I am using the grocer gem to send push notifications to the APN service. I am stuck on the certificate issue. Here's the code pusher = Grocer.pusher( certificate: "#{Rails.root}/public/certificate1.pem", # required passphrase: "", # optional gateway: "gateway.push.apple.com", # optional; See note below. port: 2195, # optional retries: 3 # optional ) notification = Grocer::Notification.new( device_token: token, alert: "#{uname} liked your post", sound: 'default', badge: 0 ) pusher.push(notification) I am in a production environment where I am hosting the app on Heroku. Heroku logs show me this OpenSSL::PKey::RSAError (Neither PUB key nor PRIV key: nested asn1 error): app/controllers/api/v1/feeds_controller.rb:49:in `likeit' Line 49 is the line where the notification is pushed. I'm certain that the certificate I'm using is proper as I have tested push notifications using it. Also when generating the pem file I have exported both the certificate as well as the private key. Reference: grocer gem Any suggestions are welcome!

undefined method 'to_model' when linking thumbnail to original image Posted: 06 Oct 2016 07:25 AM PDT I'm creating an album that I'm planning to display with Masonry and ImgZoom so that the visitors can have a bigger image when they click on it. According to ImgZoom, to make the zoom work, you need to do the following: <a href="path/to/real/image.png"> <img src="path/to/image's/thumbnail.png class="thumbnail" /> </a> So I generated an uploader, with the following inside it: class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::MiniMagick storage :file def store_dir 'portfolio/photos' end version :thumb do process :resize_to_fit => [220, nil] end end Everything works perfectly, I can call both the versions without trouble, but when I try to follow ImgZoom's instructions by doing the following: <%= @portfolio.photos.each do |p| %> #This is a nested form inside the portfolio form, so I need to do this to get my images <%= link_to image_tag p.image.thumb.url, p.image %> or: <%= link_to p.image do %> <%= image_tag p.image.thumb.url, :class => 'thumbnail' %> <% end %> I'm getting the following error: undefined method 'to_model' for #<ImageUploader:0x0000000c35f4d8> I found a similar subject on stack overflow but the asker wasn't clear and was invited to ask an other question on the forum, which I couldn't find. I can individually reach 'p.image' and 'p.image.thumb.url', but I can't make a link from one to another, which would be perfectly doable with simple html. What am I doing wrong? Thank you in advance

How to check remove image? I can not check because before save averter.present? return true Posted: 06 Oct 2016 07:37 AM PDT I use carrierwaveuploader/carrierwave: Classier solution for file uploads for Rails, Sinatra and other Ruby web frameworks. @foo.assign_attributes(update_params) #=> update_params includes "remove_avatar"=>"1" @foo.avatar.present? #=> true @foo.save @foo.avatar.present? #=> false before save present? return true. after save present? return false. My Validation validate :validate_avatar def validate_avatar # if @foo.avatar deleted and same conditions, add error end In validate_avatar, @foo.avatar.present? is true because before save. I try after_save :validate_avatar. after_save :validate_avatar def validate_avatar # if @foo.avatar deleted and same conditions, add error # then return false end Because after_save, @foo.avatar.present? is false. But Rails5 not rollback with return false. How to check @foo.avatar deleted in validation? I want to check avatar was deleted but remain image crop data. So I need check @foo.avater deleted or not delete. If avatar deleted, image crop data deleted too. So check in validation. Already made a method for delete all image crop data(xxx_crop columns) in my project.

Algolia_search on nested model Posted: 06 Oct 2016 06:28 AM PDT I got a User model, which has many Skills though his Masteries. I'm using a form to retrieve users, with Algoliasearch, and I would like to retrieve all users that have a particular skill (I.E, if I got a user called "John", which has the "Origami" skill, he should appear in results if I type "John" or "Origami") I tried to do so by mapping the nested skills, but this doesn't seem to work Here's the model class Creator < ActiveRecord::Base include AlgoliaSearch algoliasearch do # all attributes will be sent add_attribute :creator_skills end has_many :masteries has_many :skills, through: :masteries def creator_skills self.masteries.map do |s| { name: s.skill.name } end end [...] The form returns a query param, which is used to retrieve creators with @creators = Creator.where(display_index: true).algolia_search(params[:query]).shuffle Did I miss something ? Is it possible to map a nested model ?

Ruby gem cucumber SSL error and Gem sources Posted: 06 Oct 2016 07:58 AM PDT I was trying to install cucumber gem for Ruby.

How to keep array structure when saving record - activerecord/postgres Posted: 06 Oct 2016 06:57 AM PDT I created an array structure of hashes and i created a column in postgres to save that structure using the migration below class AddKeyDirectionsToEvent < ActiveRecord::Migration[5.0] def change add_column :calendar_events, :key_directions, :text, array:true, default: [] end end now, the structure of the array is the one below { :in => [ [0] { :duration => "5 mins", :distance => "0.4 km", :travel_mode => "WALKING", :travel_type => nil }, [1] { :duration => "12 mins", :distance => "5.3 km", :travel_mode => "TRANSIT", :travel_type => "SUBWAY" }, [2] { :duration => "9 mins", :distance => "0.7 km", :travel_mode => "WALKING", :travel_type => nil } ] } { :out => [ [0] { :duration => "10 mins", :distance => "0.7 km", :travel_mode => "WALKING", :travel_type => nil }, [1] { :duration => "12 mins", :distance => "5.3 km", :travel_mode => "TRANSIT", :travel_type => "SUBWAY" }, [2] { :duration => "6 mins", :distance => "0.4 km", :travel_mode => "WALKING", :travel_type => nil } ] } but for some reason in database it is saved like this ["{:in=>[{:duration=>\"5 mins\", :distance=>\"0.4 km\", :travel_mode=>\"WALKING\", :travel_type=>nil}, {:duration=>\"12 mins\", :distance=>\"5.3 km\", :travel_mode=>\"TRANSIT\", :travel_type=>\"SUBWAY\"}, {:duration=>\"9 mins\", :distance=>\"0.7 km\", :travel_mode=>\"WALKING\", :travel_type=>nil}]}", "{:out=>[{:duration=>\"10 mins\", :distance=>\"0.7 km\", :travel_mode=>\"WALKING\", :travel_type=>nil}, {:duration=>\"12 mins\", :distance=>\"5.3 km\", :travel_mode=>\"TRANSIT\", :travel_type=>\"SUBWAY\"}, {:duration=>\"6 mins\", :distance=>\"0.4 km\", :travel_mode=>\"WALKING\", :travel_type=>nil}]}"] any ideas why? I tried chanign the type of array from :text, to :varchar and got same result. The only solution i found is using eval command to convert string back to array which is not ideal.
