MySQL utf8mb4 in Codeship Posted: 10 Jun 2016 07:12 AM PDT I'm running automated tests for a Rails app in Codeship, and I'd like to use utf8mb4 as the database encoding. Here's my modified database.yml: test: adapter: mysql2 host: localhost encoding: utf8mb4 collation: utf8mb4_unicode_ci pool: 10 username: <%= ENV['MYSQL_USER'] %> password: <%= ENV['MYSQL_PASSWORD'] %> database: test<%= ENV['TEST_ENV_NUMBER'] %> socket: /var/run/mysqld/mysqld.sock I followed this tutorial: https://codeship.com/documentation/databases/mysql/ , but the encoding is still utf8. How can I run the tests using a utf8mb4 encoding for the database?

Heroku - Getting a SQLite error even though it is not in the Gemfile Posted: 10 Jun 2016 07:14 AM PDT I've removed the sqlite3 gem from my gemfile and replaced it with pg, deleted the gemfile.lock and re-bundled, and there are no dependencies in the new gemfile.lock which require sqlite3, so why am I still getting this error? Answered now, thanks!

Ruby on Rails: List of errors which each element contains the relationship Posted: 10 Jun 2016 06:57 AM PDT how can I generate a list of errors for the forms which each element contains the relationship (using for example an data-field attribute) with its field when it's possible? For exemple: <form> <div id="error_explanation"> <ul> <li data-field="username_name">username can't be blank</li> <li data-field="email_name">email address can't be blank</li> <ul> </ul> <label for="username_field">Username</label> <input id="username_field" name="username_name" type="text"/> <label for="email_field">Username</label> <input id="email_field" name="email_name" type="text"/> </form> Thanks!

Calling a method of another controller Posted: 10 Jun 2016 07:14 AM PDT I have two controllers named Children and Father where I need to call a method of FatherController and MotherController from ChildrenController. I need to pass a JSON data to the FatherController get_details method from set_details method of ChildrenController. There is no route for get_details method in both controllers. I don't need any helper methods to write. I need to call more than one Controller's method, not by Inheriting. Father controller class FatherController < ApplicationController def get_details(data) ## ## I need to do some operation with the 'data' received from children controller. end end Mother controller class MotherController < ApplicationController def get_details(data) ## ## I need to do some operation with the 'data' received from children controller. end end Children controller class ChildrenController < ApplicationController data = { "id":"2", "expiry_date":"25-09-2016" }.as_json def set_details ## get_details(data) -> FatherController ## get_details(data) -> MotherController end end Please help how to do this or suggest me if there is any other way to do this. Thanks.

Strong Parameters for nested omniauth Posted: 10 Jun 2016 07:02 AM PDT I have a Rails 4.0.13 app using Devise 3.5.10. My User model is :omniauthable using a nested authentications has_many relation, so the user can Omniauth by several providers: class User < ActiveRecord::Base devise :database_authenticatable, :registerable, :confirmable, :recoverable, :rememberable, :trackable, :omniauthable, :omniauth_providers => Authentication.auth_methods has_many :authentications, dependent: :destroy accepts_nested_attributes_for :authentications end (I originally implemented this some time ago on Rails 3.2, so I don't recall the exact changes I had to make to make this work. I don't believe it's relevant, but can try to look it out if necessary). This means that a User sign-up using Omniauth has parameters like: Parameters: {"utf8"=>"✓", "user"=>{ "authentications_attributes"=> {"0"=>{"provider"=>"open_id", "uid"=>"http://pretend.openid.example.com?id=12345", "nickname"=>"http://pretend.openid.example.com"}}, "name"=>"Person1", "email"=>"Person1@example.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up"} I cannot figure out how to get strong parameters to permit this. My current attempt is params.require(:user).permit(:name, :email, :password, :password_confirmation, authentications_attributes: {"0" => [:provider, :uid, :nickname]}), but that still produces a log of Unpermitted parameters: provider, uid, nickname. How can I permit these parameters?

Configure Rails 3 for S3 bucket using fog.yml Posted: 10 Jun 2016 06:49 AM PDT I have this Rails 3.2 application passed on from the previous freelancer in my company. I would like to know as to how to configure this existing S3 bucket to my new EC2 Instance. Access to AWS is configured in fog.yml by using fog gem as well as carrierwave gem. Need urgent help. Thanks in Advance.

Can't get ng-sortable to work Posted: 10 Jun 2016 06:48 AM PDT I'm incorporating ng-sortable into a legacy Angular/Rails project. My template includes this (HAML): %ul(as-sortable="dragQuestions" ng-model="questions") %li(ng-repeat="question in questions") %div(as-sortable-item-handle) {{ question.text }} When I load the page I get: Controller 'asSortableItem', required by directive 'asSortableItemHandle', can't be found! I'm somewhat at a loss as to how to troubleshoot. Any suggestions?

Rails update instance variable on ajax call to a method from the same controller Posted: 10 Jun 2016 07:13 AM PDT I have a view that is handled by a simple controller: class CountController < ApplicationController def count @index = 0 end end In my view I just added a button: <%= link_to "Change next day", increase_count_path(@index), :class => 'btn' :remote => true %> The request is being handled by a method I added in the CountController: def increase_count @index = params[:index].to_i + 1 end After trying it, I saw that each time the request is being sent to /increase_count/0 , so this obviously doesn't update the variable as I'd like it to. So my guess is, the 2 are not linked. The first one has its scope in the view, and the second one, from the increase_count method is visible in whatever javascript I would render from it. How can I achieve this in Rails? The thing I was trying to achieve and ran into this was the following (simplified version): I have an array of 3 Strings. Firstly I display the first one. On click I would like to make an Ajax call, increment the index, and display the next string. But I ended up showing only the second one, because the next calls don't update the index.

Can't save polygon with PostGIS via ActiveRecord Posted: 10 Jun 2016 06:36 AM PDT I have a problem using PostgreSQL with PostGIS via ActiveRecord. I'm using: Rails 4.1.5 activerecord-postgis-adapter 2.2.0 PSQL 9.3.4 When I trying to save polygon in DB, some of it saves but some are not, just returns nil for geometry column. All polygons are valid, i've check its using ST_Valid function. polygon = <polygon> # see below Area.find(1).update(geometry: polygon) > UPDATE "areas" SET "geometry" = $1 WHERE "areas"."id" = 1 [["geometry", nil]] Direct SQL query works great, all geometry updates properly. SQL select query returns geometry or polygon. SELECT *, ST_ASText(geometry) as geom from areas where id=1 select results screen ActiveRecord still returns geometry as nil. Area.first => #<Area id: 1, name: "Южный", geometry: nil> schema: create_table "areas", force: true do |t| t.string "name" t.spatial "geometry", limit: {:srid=>4326, :type=>"geometry"} end

adding each_slice(3) gives Error in rails App Posted: 10 Jun 2016 06:45 AM PDT I´m working on this do loop in my app, it works fine but I want to take it further(see below) and I´m not sure how to do that. ( I´m a rails newbie) <div class="row"> <% @products.each do |category, products| %> <% products.each_with_index do |product, index| %> <% if index == 0 %> <div class="col-lg-4 col-sm-6 col-xs-12 center-block " > <%= image_tag product.image.url(:medium), class: "img-responsive" %> <div class="caption"> <p><%= product.category.name %></p> </div> <% end %> </div> <% end %> <% end %> </div> At the moment the loop is looping through 12 categories and displaying one image from each category. I don´t want to have all the images appearing in the same row. I tried to add each_slice(3) to the loop but it gives me this error undefined method 'image' for 5:Fixnum this is how the code looks after the each_slice(3) insertion <% @products.each_slice(3) do |category, products| %> <div class="row"> <% products.each_with_index do |product, index| %> <% if index == 0 %> <div class="col-lg-4 col-sm-6 col-xs-12 center-block " > <%= image_tag product.image.url(:medium), class: "img-responsive" %> <div class="caption"> <p><%= product.category.name %></p> </div> <% end %> </div> <% end %> <% end %> </div> I´m not sure what to do here or if each_slice(3) is the right way to do this. I hope someone here can guide me through this thanks D

Live branding semantic-ui on rails Posted: 10 Jun 2016 06:24 AM PDT I'm using rails 4 with the less-rails-semantic-ui gem and I need to allow for custom branding on a per-user basis. I like how semantic has variables that can be set on the top level and propagated through the rest of the css, but an initial render after changing a variable can take up to 15 seconds to load the page. Is there a way to take advantage of semantic-ui's variables and implement per-user branding, while keeping decent page load times? Can I precompile all of the assets that don't include specific variables, and then compile those on render? One possibility is to duplicate the code from the gem and render a css.erb file that is loaded on each request. But that feels messy.

Rails Custom Validation/Callback from External API Posted: 10 Jun 2016 05:34 AM PDT Using Easy Post API, I want to validate customer addresses, update my DB with the easy post response, and also provide useful feedback to my users...but what is correct? #3 below is what I really need help with! Should I use EP response to update user-input (meaning a user will see their zip/city/street updated to something different than they entered), or just tie that record to the easy_post id, so I can retrieve that info from EP, but users will still see their own address as they entered it (provided it's valid)? How do I provide individual field verifications? Granted, this is sloppy, but I need feedback/help. Should I initialize EasyPost every time this callback is performed? If I should update the db from EP's response, is this the right way? EP response error hash will have a key for each field that's no good. How can I use that to mark those fields invalid in the rails way? validate :easy_post_valid def easy_post_valid addr = self begin EasyPost.api_key = ENV['EP_SECRET_KEY'] address_check = EasyPost::Address.create( verify: ["delivery"], street1: addr.street1, # street1 will fail validation city: addr.city, state: addr.state, zip: addr.zip, country: "US" ) if !address_check.verifications.delivery.success address_check.verifications.delivery.errors.each do |e| errors.add :base, e.message end puts address_check.verifications return false elsif address_check.verifications.delivery.success self.ep_id = address_check.id self.street1 = address_check.street1 self.street2 = address_check.street2 self.city = address_check.city self.state = address_check.state self.zip = address_check.zip self.city = address_check.city end end true end

Devise current_user undefined after sign up but not login Posted: 10 Jun 2016 05:26 AM PDT I have a user model with an admin submodel. class Admin < User end I have devise set up and a 'type' column in the user model.

Lloop showing unwanted div´s when going through categories Posted: 10 Jun 2016 05:40 AM PDT I´m working with this loop in my views/pages/index.html.erb <div class="container-fluid"> <div class="row"> <% @products.each do |category, products| %> <% products.each_with_index do |product, index| %> <div class="col-lg-4 col-sm-6 col-xs-12 center-block"> <% if index == 0 %> <%= image_tag product.image.url(:medium), class: "img-responsive" %> <div class="caption"> <p><%= product.category.name %></p> </div> <% end %> </div> <% end %> <% end %> </div> </div> it works fine and does what it is supposed to do which is to loop through each category and present the last picture added to each category. But the problem is when I´m adding products and assigning them to categories in views/products/new.html.erb the loop above seems to add extra empty div'sto the row. I don´t understand why it is doing that... can anyone give me a hint why this is happening? this is a screenshot how it appears in google dev tools As you can see there are four empty unwanted divs in the row.

How to handle "puts 'Found!' if User.where(id: 0)" in Rails? Posted: 10 Jun 2016 05:26 AM PDT Take a look at these codes. pry> puts User.find_by(id: 0) ? 'Found!' : 'Not found' Not found pry> puts User.where(id: 0) ? 'Found!' : 'Not found' Found! The first one is ok but the second one User.where(id: 0) returns an empty Array which is evaluated as true in an if condition clause in Ruby. I know there are some ways to avoid this problem. One of them is using empty? or present? method when you try to fetch "multiple rows" like: users = User.where(country: 'vietnam') if users.empty? ... I think it's ok to use empty? or present?. But when you try to fetch a single row, you don't have to use such methods because when there is no row, it returns nil. What I'm worried about is that sometimes you need empty? and sometimes you don't need empty?. Then the codes becomes hard to read. So I thought it might be good that I always use empty? whether a method returns multiple rows or a single row. But now I don't want to see empty? methods all over my codes. Is there any good way to handle this?

Can you copy/move an uploaded file from one model to another model Posted: 10 Jun 2016 04:36 AM PDT Is it possible to copy/move a file from one model to another model. I have two models TemporaryAttachment and DocAttachment. TemporaryAttachment is to temporary store the files the user uploads while they are processing a form. Once they are finished and they want to submit their data it should move/copy the TemporaryAttachments temp_attachment attribute to DocAttachments attachment attribute. Below is the TemporaryAttachment model class TemporaryAttachment < ActiveRecord::Base has_attached_file :temp_attachment, storage: :filesystem, path: 'public/assets/dev/images/docs/:id_partition/:filename', url: Rails.application.config.x.local_url validates_attachment_presence :temp_attachment do_not_validate_attachment_file_type :temp_attachment validates_attachment_size :temp_attachment, less_than: 10.megabytes end Below is the DocAttachment model class DocAttachment < ActiveRecord::Base belongs_to :doc_attachment_type belongs_to :language belongs_to :upload belongs_to :creator, foreign_key: 'creator_id', class_name: 'User' has_attached_file :attachment before_save :rename_file validates_attachment_presence :attachment validates_attachment_content_type :attachment, content_type: %w(application/pdf application/vnd.ms-excel application/vnd.openxmlformats-officedocument.spreadsheetml.sheet application/msword application/vnd.openxmlformats-officedocument.wordprocessingml.document text/plain), size: { :in => 0..10.megabytes } validates :doc_attachment_type_id, presence: true validates :code, presence: true validates :title, presence: true validates :language_id, presence: true def rename_file extension = File.extname(attachment_file_name).gsub(/^\.+/, '') filename = attachment_file_name.gsub(/\.#{extension}$/, '') new_attachment_file_name = "#{self.code}-#{self.language.name}.#{extension}" attachment.instance_write(:file_name, new_attachment_file_name) end end This is the TemporaryAttachments controller which is called to upload one or more files class TemporaryAttachmentsController < ApplicationController def create temp_doc_attachment_params[:temp_attachment_array].each do |file| @temp_attachment = TemporaryAttachment.new @temp_attachment.temp_attachment = file @temp_attachment.save end redirect_to new_upload_path end private def temp_doc_attachment_params params.require(:temporary_attachment).permit(temp_attachment_array: []) end end This is the uploads controller which is used to copy temp attachments over to doc attachments and sets a couple other attributes. class UploadsController < ApplicationController def new @upload = Upload.new @temp_attachments = TemporaryAttachment.all @languages = Language.order(:name) copy_temp_attachments @doc_attachments = @upload.doc_attachments end def create @upload = Upload.new(upload_params) if @upload.save TemporaryAttachment.destroy_all render doc_attachments_confirmation_path else render action: 'new' end end def delete end private def upload_params params.require(:upload) .permit(doc_attachments_attributes: [ :id, :code, :title, :language_id, :doc_attachment_type_id ]) end def params_with_user form_params = doc_attachment_params form_params[:creator_id] = @user.id form_params end def copy_temp_attachments if @temp_attachments.present? @temp_attachments.each do |temp_file| get_file_details temp_file.temp_attachment_file_name @upload.doc_attachments.build({attachment: temp_file.temp_attachment, code: @details.first, language_id: @details.last}) end end end def get_file_details(filename) @details = filename.split('-') extension = File.extname(@details.last).gsub(/^\.+/, '') filename = @details.last.gsub(/\.#{extension}$/, '') filename = 'wel' if filename.eql? "cym" language = Language.where('languages.name LIKE :lang', {:lang => "%#{filename.capitalize}%"}) @details[2] = language.first.id end end When I try this I an error stating that doc_attachments.attachment can't be blank. I'm assuming thats being the model is looking for a file and its not available. Any help greatly appreciated.

Why does Mongoid's "presence" validation enable autosave? Posted: 10 Jun 2016 05:10 AM PDT I had a hard time debugging this one and I was about to ask for help. But I've managed to identify the cause and would like to share my findings in case someone else is running into the same problem. [And maybe someone can explain why it works the way it does] Setup Let's say I have two Mongoid-Documents, Customer and Order with a 1:n relation. In addition, Customer has an after_save callback to synchronize document changes with an external API: class Customer include Mongoid::Document has_many :orders after_save do puts "synchronizing customer" # <- not my actual code end end class Order include Mongoid::Document belongs_to :customer validates_presence_of :customer end Everything works as expected. Creating and updating customers results in the after_save callback being triggered and creating orders does not. Change After a while, Customer needs a new field with a default value: class Customer # ... field :premium, type: Boolean, default: false end Problem But all of a sudden, things get weird. After this change, creating (or updating) orders result in the customer being saved as well! (I noticed this because of my logs – the synchronization was running for no apparent reason) c = Customer.last c.orders.create synchronizing customer # <- what the? #=> #<Order _id: 575a995aab265d730b8bddba ...> Strangely, this only happens for existing customers and it only occurs once. Cause A long and tedious debugging session revealed that the Order's belongs_to relation has an autosave flag: Order.relations['customer'].autosave? #=> true It was enabled by the presence validation and in fact, Mongoid's documentation notes it casually: Note that autosave functionality will automatically be added to a relation when using accepts_nested_attributes_for or validating presence of the relation. But autosave only saves a document if it was changed, so where did the change come from? Apparently, my new premium field with the default value introduced a subtle change: c = Customer.first # a customer from before the change without "premium" attribute c.changed? #=> true c.changes #=> {"premium"=>[nil, false]} Solution After all, the fix was quite trivial. I just had to explicitly disable autosave on my belongs_to relation: class Order include Mongoid::Document belongs_to :customer, autosave: false validates_presence_of :customer end Open Questions But the question remains: Why does Mongoid's "presence" validation enable autosave? How could this be the desired default behavior? Please enlighten me.

Disable s3_uploader_form once image is uploading or uploaded to s3 Posted: 10 Jun 2016 06:21 AM PDT I am uploading images on s3 through s3_direct_upload gem. I want to upload one image at a time.
