With password is the plain text of password_digest, which was encrypted by bcrypt.

I uasually use rails consle to debug. So anyone can help me how to know the plain text of encrypted_password. |

| Rails delayed job and docker: adding more workers Posted: 21 Jan 2017 06:57 AM PST I run my rails app using a Docker. Now delayed jobs are processed by a single worker that runs in a separate contariner called worker and it runs with a command bundle exec rake jobs:work. I have several types of jobs that I would move to a separate queue and create a separate worker for that or at least have two workers for process tasks. I tested run my worker container with env QUEUE=default_queue bundle exec rake job:work && env QUEUE=another_queue bundle exec rake job:work bit that do not make any sense. It does not fails, is starts but jobs aren't processed. Is there any way to have separate workers in one container? And is it correct? Or should I create separate container for each worker I would ever want to make? Thanx in advance! |

| Using Wikipedia-Client Gem to Update Rails Database Posted: 21 Jan 2017 05:53 AM PST My ruby and Rails is a bit rusty. I have a table in my database called institutes which has some of the columns filled. I want to use the Wikipedia-Client gem to fill some of the others. I want to use the name attribute to find the page on Wikipedia then use page.summary for the description attribute in my table and page.image_urls.first for the picture attribute. At the moment, I'm struggling to work out how I would go about this. My current code is: require 'Wikipedia' Institute.each do |institute| school = institute.pluck(:name) page = Wikipedia.find(school) description = page.summary picture = page.image_urls.first Institute.update!(description: description, picture: picture) end
I'm clearly doing something wrong here to do with the selection and use of the name attribute to find the Wikipedia page, but can't quite work it out. I think even if I were to pluck the name correctly, it wouldn't assign anything to the right id. If there's also a way to drop the "The" at the beginning of the name in the Wikipedia search if it exists in :name, that would also be helpful as it seems some institutes drop this on Wikipedia. |

I'ved added a before_filter in my application controller like so before_filter :add_domain_view_paths def add_domain_view_paths prepend_view_path "app/views/shared" prepend_view_path "app/views/#{app_domain}" end
After making this change and moving all current views into the app/views/shared my app suddenly started to slow down and also leak memory. No other changes were made at the time This graph shows response times before and after making the change  Performance also seems to degrade when leaving the views in their original app/views/controller_name folder and only including the include filter as I've described above. Though there still seems to be a memory leak originating from this before_filter. What am I doing wrong? |
| Rails; Fetch records within initializer Posted: 21 Jan 2017 05:23 AM PST I've been wondering it is common to fetch records within initializer? Here this is an example for service object to fetch records and generated pdf receipt file. Input is invoice uuid, and fetch the related records such as card detail, invoice items within initialier. class Pdf::GenerateReceipt include Service attr_reader :invoice, :items, :card_detail def initialize(invoice_uuid) @invoice ||= find_invoice!(invoice_uuid) # caching @items = invoice.invoice_items @card_detail = card_detail end ..... def call return ReceiptGenerator.new( id: invoice.uuid, # required outline: outline, # required line_items: line_items, # required customer_info: customer_info ) rescue => e false, e end ..... def card_detail card_metadata = Account.find(user_detail[:id]).credit_cards.primary.last card_detail = {} card_detail[:number] = card_metadata.blurred_number card_detail[:brand] = card_metadata.brand card_detail end end Pdf::GenerateReceipt.('28ed7bb1-4a3f-4180-89a3-51cb3e621491') # => then generate pdf
The problem is if the records not found, this generate an error. I could rescue within the initializer, however that seems not common. How could I work around this in more ruby way? |
| missing requiered keys: [:post_id], add comments to post on a page with many posts Posted: 21 Jan 2017 07:15 AM PST I'm trying to add comments to my posts. When I have done that successfully before I cannot get it right now. The problem is that I have lots of posts on the same page, all of them with a comment box underneath (much like any social network). However the page will not even render displaying this error: No route matches {:action=>"new", :controller=>"comments", :post_id=>nil} missing required keys: [:post_id]
Although its sending the right project id, it cannot find the post_id as there are many posts on the page (I think thats the problem... right?). Please see below my associations: routes.rb resources :projects do resources :comments, :posts end resources :posts do resources :comments end

| Rails 5 - vendor assets are not loaded on production (fonts only) Posted: 21 Jan 2017 06:31 AM PST It's perfectly working in development, but not in production. It's not finding the following files: /assets/fontello.woff
/assets/fontello.ttf Here is the setup: - fonts files:
assets.rb
Rails.application.config.assets.paths << Rails.root.join('app', 'vendor', 'assets', 'fonts') Rails.application.config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/
fontello.css
@font-face { font-family: 'fontello'; src: url('/assets/fontello.eot'); src: url('/assets/fontello.eot#iefix') format('embedded-opentype'), url('/assets/fontello.woff') format('woff'), url('/assets/fontello.ttf') format('truetype'), url('/assets/fontello.svg#fontello') format('svg'); font-weight: normal; font-style: normal; }
As I said, everything is working fine in development. I have try a lot of things. For example: - moving the fonts in the public folder (as my images there are loaded)
add the following line in the assets.rb: Rails.application.config.assets.precompile += [/^[-_a-zA-Z0-9]*\..*/]
but nothing worked. Could you advise anything else to try? |
| Bundler trying to install development gems in production Posted: 21 Jan 2017 04:03 AM PST When I try to deploy my Rails 5 application using Capistrano 3, it tries to install development gems even in staging. This is completely new behaviour and I have no idea where it's coming from (came in the middle of a bunch of commits to a controller, the deploy scripts or Gemfile weren't touched at all). The relevant lines of the capistrano.log are: bash: line 1: 13108 Killed /path/to/my/app/rvm1scripts/rvm-auto.sh 2.4.0 bundle install --path /path/to/my/app/shared/bundle --without development test --deployment --quiet bundle stderr: Nothing written ** DEPLOY FAILED ** Refer to log/capistrano.log for details.
My capistrano.log can be found at this gist, but the gist of it is that it checks the bundle, which fails because the group :development gems aren't installed (obviously), and then tries to bundle install, which won't happen because they're in the development group. It's a weird, cyclical problem. |

and so on. I want to get the 8 figure reference, the 4 figure reference and the school name saved to my database under UKPRN, instid and name respectively.

So far my code in irb looks like this: require 'nokogiri' require 'open-uri' page = Nokogiri::HTML(open(url)) rows = data.css("tr") rows.each do |row| name = row.css("td")[2] ukprn = row.css("td")[0] instid = row.css("td")[1] end
This seems to work ok as when I print one of the variables it seems to pick up the right data, but I can't get rid of the tags around the text, and once done, I'm not sure how I would go about saving this data to my institute model in the database. The attributes should correlate with the names given above. Any help is appreciated. |

| Rails Associations - undefined method for nil:NilClass Posted: 21 Jan 2017 01:41 AM PST Basic question on Rails associations with the following tables: - Shop: name, network
- Product: title, price, shop_id
Relation defined as has_many and belongs_to: Model: shop.rb class Shop < ApplicationRecord has_many :products end
product.rb class Product < ApplicationRecord self.primary_key = "id" belongs_to :shop end
Controller: shops_controller.rb def show @shop = Shop.find(params[:id]) end

In the Shop view I manage to reference and show all Products for each Shop without problems: <%= @shop.name %> <%= @shop.network %> <% @shop.products.each do |product| %> <%= product.title %> <% end %>
But the other way around in the Product view I don't manage to show the network information from the Shop table : <%= @product.title %> <%= @product.shop.network %>
This returns the following error: undefined method `network' for nil:NilClass

| Dynamically include associations for objects in Rails Posted: 21 Jan 2017 01:28 AM PST I am currently developing a small Rails 5 application where I need to pass on an ActiveRecord object to an external service based on certain events. In my model I have defined the following: # /models/user.rb after_create :notify_external_service_of_user_creation def notify_external_service_of_user_creation EventHandler.new( event_kind: :create_user, content: self ) end
The EventHandler is then converting this object to JSON and is sending it through an HTTP request to the external service. By calling .to_json on the object this renders a JSON output which would look something like this: { "id":1234, "email":"test@testemail.dk", "first_name":"Thomas", "last_name":"Anderson", "association_id":12, "another_association_id":356 }
Now, I need a way to include all first level associations directly into this, instead of just showing the foreign_key. So the construct I am looking for would be something like this: { "id":1234, "email":"test@testemail.dk", "first_name":"Thomas", "last_name":"Anderson", "association_id":{ "attr1":"some_data", "attr2":"another_value" }, "another_association_id":{ "attr1":"some_data", "attr2":"another_value" }, }
My first idea was to reflect upon the Model like so: object.class.name.constantize.reflect_on_all_associations.map(&:name), where object is an instance of a user in this case, and use this list to loop over the associations and include them in the output. This seems rather tedious though, so I was wondering if there would be a better way of achieving this using Ruby 2.4 and Rails 5. |

which is giving me this error message, highlighting the line @language_role = current_user.language_roles.build : "undefined method `language_roles' for nil:NilClass" I have three tables: create_table "language_roles", force: :cascade do |t| t.integer "language_id" t.boolean "is_active" t.boolean "is_teacher" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.integer "user_id" t.index ["user_id"], name: "index_language_roles_on_user_id" end create_table "languages", force: :cascade do |t| t.string "lang_name" t.datetime "created_at", null: false t.datetime "updated_at", null: false end create_table "users", force: :cascade do |t| t.string "email", default: "", null: false t.string "encrypted_password", default: "", null: false t.string "reset_password_token" t.datetime "reset_password_sent_at" t.datetime "remember_created_at" t.integer "sign_in_count", default: 0, null: false t.datetime "current_sign_in_at" t.datetime "last_sign_in_at" t.string "current_sign_in_ip" t.string "last_sign_in_ip" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.index ["email"], name: "index_users_on_email", unique: true t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true end
The language_roles table is meant to allow a user to have many languages, as well as many roles within that language. Here are my class definitions: class LanguageRole < ApplicationRecord belongs_to :languages belongs_to :users end class Language < ApplicationRecord has_many :language_roles has_many :users, :through => :language_roles end class User < ApplicationRecord has_many :language_roles has_many :languages, :through => :language_roles # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable end
My root path goes to 'home#index', where the user is supposed to pick a language if current_user.language_roles is empty. As such, I put this code in my home controller and language_roles controller: class HomeController < ApplicationController def index @language_role = current_user.language_roles.build end end class LanguageRolesController < ApplicationController def create @language_role = current_user.language_roles.build(language_role_params) if @language_role.save redirect_to root_path else redirect_to :back end end private def language_role_params params.permit(:language_id) end end
What in the hell is the problem?? I assume I need to instantiate the variable somehow, but I'm not sure how. Thanks, Michael |
| Build method is not associating in Rails Posted: 20 Jan 2017 06:56 PM PST I'm still newbie in Rails, but got confused with the initialization of a HABTM association. Reading its documentation, it says When initializing a new has_one or belongs_to association you must use the build_ prefix to build the association, rather than the association.build method that would be used for has_many or has_and_belongs_to_many associations. So, basically, let's suppose we have two models: class User < ApplicationRecord has_and_belongs_to_many :organizations end class Organization < ApplicationRecord has_and_belongs_to_many :users end
Inside organization_controller, since I'm using Devise, my create method should have something like this: @organization = current_user.organizations.build(organization_params) @organization.save
However, it is not working. With byebug, I checked that for the current_user.organizations, the new organization was there, but, if I call @organization.users, there's an empty array. Looks like it's required to run current_user.save as well, is it correct? I was able to associate both models with this code: @organization = Organization.new(organization_params) @organization.users << current_user @organization.save

| Tinymce default styles in Rails app Posted: 20 Jan 2017 04:49 PM PST I was following the tutorial on How to build a blog with Rails 5 and Bootstrap 4 - Part 5, initialized Tinymce Editor but I can't change the default font size of text in this editor. I have this code in application.js: document.addEventListener("turbolinks:load", function() { tinymce.remove(); tinymce.init({ selector: 'textarea#post_body', height: 500, plugins: [ "advlist autolink autosave link image lists charmap", "wordcount media code", "table contextmenu textcolor paste" ], toolbar1: "undo redo | bold italic underline strikethrough | alignleft aligncenter alignright alignjustify | styleselect formatselect fontselect fontsizeselect", toolbar2: "cut copy paste | bullist numlist | outdent indent blockquote | link image media | forecolor | table | subscript superscript | charmap | code", menubar: false, content_css : "/assets/application.css" });
}) In application.css: *= require_tree . *= require_self @import "bootstrap-sprockets"; @import "bootstrap"; @import "font-awesome";
And there are other two files with styles (custom.scss and posts.scss). I tried putting in custom.scss: body.mce-content-body { font-size: 16px; background-color: gray;} body.mce-content-body p { font-size: 16px;} [data-mce-style] { font-size: 16px;}
I also tried the following: -clearing browser cache several times -copying custom.scss and linking to the new file in content_css as per this suggestion -using content_style: ".mce-content-body p { font-size: 16px;}" The file is being added to the head of the iframe and its background color is changing, but the styles for paragraphs are always being overwritten by their default inline styles :<p style="box-sizing: border-box; margin: 0px 0px 1.1em; padding: 0px; border: 0px; font-size: 19.35px; line-height: 32.895px; font-family: Lato, sans-serif; color: #444444;" data-mce-style="box-sizing: border-box; margin: 0px 0px 1.1em; padding: 0px; border: 0px; font-size: 19.35px; line-height: 32.895px; font-family: Lato, sans-serif; color: #444444;">...</p> Another problem is that even if I change the background-color while editing post, the default styles are back when I submit the form and show all blog posts :( Any ideas, please? |
| ODD ISSUE: Heroku app works great on few computers but not the others. Could running "heroku restart" cause the issue? Posted: 20 Jan 2017 05:59 PM PST I am running into a very odd issue and coming up short with identifying the issue. I don't even know if it is a front-end, server or heroku issue. Please help me out. I am managing a Rails App (with React front-end), hosting on Heroku. It is a workforce management and dispatching app. It has been working fine the whole time, until earlier today, when I made a huge feature deployment. The deployment was successful, and I tested the old & new features fine on all of our testing computers. After deployment, I ran heroku run rake db:migrate and heroku restart. During this time, we have customers using the web app on their local computers, in different time zones. Few minutes later, I got a call from multiple customers, each mentioning that at least one of their dispatching features is not working, all of which were older features/components that shouldnt have been affected. Some say they cant see their workers. One say they cant see jobs on a particular day. Some say they cant see jobs on another. When I check the heroku logs, I see no errors whatsoever. Routes are called fine and things are passed correctly back to the front-end. When logging into their app with master credentials, we also were unable to replicate ANY of these issues on ANY of our computers. All of our customers uses Chrome, but checking on both Mac and Windows reveal no issues from our ends. Yet, the issue still remains. We then decided to revert our deployment and deployed an earlier version. Same thing. Everything works on ours, and customers continue to say these features/components just appear...blank. We tried heroku run rake tmp:clear to clear heroku cache, still no luck. Thank you. Any comments will be highly appreciated. |
| Strong Params: params.permit returns Unpermitted parameters despite whitelist Posted: 20 Jan 2017 06:54 PM PST UsersProfileController has strong params that looks like so: def user_profile_params params.permit(:age, :relations) # yes, I am not requiring user_profile. Just permitting attributes I need. end
The create action builds UserProfile through a parent (has-one and belongs-to association) def create parent = Parent.create_guest parent.build_user_profile(user_profile_params) if parent.save # do something else # handle error end end
Calling params in UserProfiles returns: <ActionController::Parameters {"age"=>"23", "relations"=>"3", "subdomain"=>"api", "format"=>:json, "controller"=>"api/v1/user_profiles", "action"=>"create"} permitted: false>
Calling user_profile_params, returns this: user_profile_params: Unpermitted parameters: subdomain, format <ActionController::Parameters {"age"=>"23", "relations"=>"3", } permitted: true>
When a post request comes in, I expect to be able to create user_profile using the whitelisted params in user_profile_params. Instead, the create action in UserProfiles fails with error: Unpermitted parameters: subdomain, format. This isn't what I expected. I expected user_profile_params to only include the permitted values and ignore all others. I could add :format and :subdomain to list of permitted attributes but something feels a bit off about that. Can someone explain what is going on/what I am missing? |
