| Ruby On Rails help on Paper_trail gem Posted: 14 Dec 2016 07:55 AM PST So I have a project with authentication of users, and history tracking of some models. For the history I use the paper_trail gem, I have a problem of filtering the history to show to the user, I have configured it to track the current_user id into the Whodunnit field. My user has role_id which specifies the role from the Roles table Also i have another table with some items that have id and user_id fields. And now my problem is how to take specific rows from Versions table according to the role of the user, like for ex: if user role is 'SomeRole' it has to return only those actions done by the users that have the same role 'SomeRole'. I know that i can take out all the actions by @versions = PaperTrail::Version.order('created_at')
but have no idea on how to filter to select only those that are satisfying for my uses. Is there an easy way to do it or should i hardcode it like selecting one by one, than check all user_id of their roles and so on so forth? Hope you understood my messy way of explaining |
| Seamless staging experience on production app Posted: 14 Dec 2016 07:54 AM PST Problem My ios app uses webview but I want to support a staging server for all internal people. The issue is that I don't want to have two apps on the app store. Also, I don't want to have to have to manually release a second app using testflight because I want internal peoples spouses and family members to be using staging. Idea So instead, I wanted to make it that if you try and log into production app but the credentials are not in the db, then it will query the staging app and if the credentials are in that db, it will log you in to staging and redirect you to the staging url. How can this be done securely? Currently, I am using the Devise gem for authentication purposes. Hypothesis - These are the steps I hypothesize make sense - query staging for credentials
- create cookie on production
- send cookie to staging
- forward user to staging
Is this the best way of solving my problem? How do I implement this using Devise? Are there any gems out there that I should know about? |
| simple_form validation message for a field not in database Posted: 14 Dec 2016 07:57 AM PST class Customer < ApplicationRecord attr_accessor :date validates_presence_of :name, :principalAmount,:interestRate,:accountType,:duration,:date end
Except date all are there in my customers table. I am using simple_form for getting those values. But problem is that there is no validation happening for :date.For others it displays message if the field is empty. How do I display presence_of validation message in simple_form for :date. I am using bootstrap datepicker. <%= simple_form_for @customer do |f| %> <%= f.input :name,:autocomplete => :off %> <%= f.input :principalAmount,:autocomplete => :off %> <%= f.input :interestRate %> <%= f.input :accountType %> <%= f.input :duration,:autocomplete => :off %> <%= f.text_field :date, "data-provide" => 'datepicker',"data-date-format"=>"dd-mm-yyyy" %> <%= f.button :submit %> <% end %>

| Environment variables for Paperclip Posted: 14 Dec 2016 08:03 AM PST I am following this guide to get model attachments stored in S3. I am curious as to why the AWS key and secret and bucket name need to be stored in config/environments/production.rb AS WELL AS set using heroku config:set AWS_ACCESS_KEY_ID=your_access_key_id
I thought it would be one or the other. For obvious reasons, I would rather not store the key and secret in a file in a repo. |
| Array iteration in rails controller: it only puts the last value Posted: 14 Dec 2016 07:53 AM PST I have to iterate on array in my rails controller but it only returns the last value of it: array = ["a", "b", "c"] array.each do |arr| @arry = arr end
@arry gives me "c" but I want it to give me a b c So, when I add a API method in the each iteration, it only gives me a result for the "c" value but I want a result for all of them. FYI: when I iterate this array in my view, everything works |

| Using Carrierwave, how can I make sure the remote url is valid picture before trying to save it to the record? Posted: 14 Dec 2016 07:39 AM PST I was attempting to save my picture files in the following manner in my ActiveJob, but a lot of my records were showing up as invalid. After looking into why, it appears the remote url isn't finding a valid picture and is returning a 404 error message. How can I change my current setup to (1) attempt to get the picture, (2) if it's an invalid link then ignore it and still save the record -- just without the picture? My current setup... if self.headshot_url.present? player_record.remote_headshot_image_url = self.headshot_url if !player_record.valid? player_record.remote_headshot_image_url = nil end end

| I can't get a search bar to appear in my Ruby application Posted: 14 Dec 2016 05:51 AM PST I have a Ruby application and am trying to implement a search function.

| Rails - Model with attributes, which are not stored in the database Posted: 14 Dec 2016 06:56 AM PST The whole project is build like that: I've got an api which provides data and saves data. Than another Application which converts the data of the data api into "nice and clean" data. and than a frontend, which takes the nice and clean data. In the Middle part, I got the Model Field. It has multiple Attributes like: id, area, etc. those attributes are also in the schema.rb. Now I also have attributes like: field_nr which are not in the schema.rb. But taken from the api, converted and then printed as json. Now I have to read from the field model the attribute field_nr, which is not in the schema.rb/database. How can I read those attributes? Thanks for your help & just ask if something is unclear |
| Rails 5 RESTful API with advanced relations Posted: 14 Dec 2016 05:23 AM PST I have many resources with advanced relations (habtm/hm/hmt etc..), everything you can imagine, but now it's time to write a beautiful routing for this API. The problem is, I can't fin the best practices about nested resource + advanced relations ro do my routing, here is what I am trying to do: Here are my models with the concerned relations # app/models/candidate.rb class Candidate < ApplicationRecord include Sociable, Locatable belongs_to :user has_many :sourcing_accounts has_many :accounts, through: :sourcing_accounts has_many :users, through: :sourcing_accounts end # app/models/sourcing_account.rb class SourcingAccount < ApplicationRecord belongs_to :account belongs_to :candidate belongs_to :user end # app/models/user.rb class User < ApplicationRecord include Sociable has_many :candidates has_many :campaigns has_many :sourcing_account end
For this example, I am willing to permit to create a relation between a Candidate and a User by creating a SourcingAccount. resources :candidates do resources :accounts resources :users, only: [:index] do post :remove post :add end end
It generates: v1_candidate_user_remove POST /v1/candidates/:candidate_id/users/:user_id/remove(.:format) api/v1/users#remove {:subdomain=>"api", :format=>:json} v1_candidate_user_add POST /v1/candidates/:candidate_id/users/:user_id/add(.:format) api/v1/users#add {:subdomain=>"api", :format=>:json}
I did not found anything about this. Is there best practices ??? If not, what do you think would be the best for this case ? Without precisions, Rails wants to route this to users#remove and users#add, which I think is totally wrong. These actions must not belong to the users controller. Bonus: What should look like a polymorphic route to create an Account belonging to 2 other models (with presence validation) the 2 models are Source and the other one is polymorphic [Candidate,User] # for example, (they are Sociable models) |
| Problems with authorization with SecureCompare Posted: 14 Dec 2016 03:51 AM PST I wanted to build API for my existing application. The special authentication token was generated and added to the database. The problem is that when it comes to comparing between token sent by user application with the one defined in the database, I get such error: NameError (uninitialized constant ActiveSupport::SecurityUtils): app/controllers/api/v1/base_controller.rb:64:in `authenticate_user!' Rendered /home/snow/.rvm/gems/ruby-2.0.0-p643/gems/actionpack-4.0.2/lib/action_dispatch/middleware/templates/rescues/_source.erb (25.4ms) Rendered /home/snow/.rvm/gems/ruby-2.0.0-p643/gems/actionpack-4.0.2/lib/action_dispatch/middleware/templates/rescues/_trace.erb (0.8ms) Rendered /home/snow/.rvm/gems/ruby-2.0.0-p643/gems/actionpack-4.0.2/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (29.9ms) Rendered /home/snow/.rvm/gems/ruby-2.0.0-p643/gems/actionpack-4.0.2/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (74.0ms) Or you can see the response from postman:  Searching the Web for answer, it appeared that it may be caused by the incompatibility of Rails version and secure_compare method. (My application is built on Rails 4.0.2 while it is needed to use Rails 4.2.0.) Is rails upgrading the only solution for my problem, or is the any other way to securely compare tokens without using ActiveSupport::SecurityUtils ? Authentication code is here: def authenticate_user! token, options = ActionController::HttpAuthentication::Token.token_and_options(request) user_phone_number = options.blank?? nil : options[:phone_number] user = user_phone_number && User.find_by(phone_number: user_phone_number) if user && ActiveSupport::SecurityUtils.secure_compare(user.authentication_token, token) @current_user = user else return unauthenticated! end end

| Rails FactoryGirl - Create specific factories in order to meet fk dependancies Posted: 14 Dec 2016 04:09 AM PST Factories are defined in multiple files under /factories/ or in the factories.rb file spec/factories/*.rb spec/factories.rb
The model customer test needs the customer factory. This factory has a foreign key pointing to an address factory. - Address factory is defined in
/spec/factories.rb - Customer factory is defined in
spec/factories/customer.rb Now if i run rspec spec/model/customer_spec.rb
i get the following error postgresql_adapter.rb:602:in `exec_prepared': PG::ForeignKeyViolation: ERROR: insert or update on table "customers" violates foreign key constraint "fk_rails_580b7e1bd8" (ActiveRecord::InvalidForeignKey) DETAIL: Key (address_id)=(1) is not present in table "addresses". : INSERT INTO "customers" ("date_of_birth", "created_at", "updated_at", , "female_household_members", "male_household_members", "pin_code", "national_id", ) VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9) RETURNING "id"
FactoryGril tries to build the customer factory first and failes because of the missing entry in the address table. How can i avoid these dependency issues? Can i somehow define to build some basic factories first ? |
| Ruby-On-Rails how to display image uploaded by user Posted: 14 Dec 2016 04:32 AM PST I am using Carrierwave so that a user can upload an image. I am making a blog website. I have no errors but the image is not appearing. I want the image to appear in the post VIEW. Here is my code: Post.rb mount_uploader :image, ImageUploader
Posts _form.html.erb <div> <%= form_for @post do |f|%> <%= f.label :image %> <%= f.file_field :image %> </div>
image_uploader.rb def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end def extension_white_list %w(jpg jpeg gif png) end
Posts show.html.erb <strong>Image:</strong> <%= image_tag @post.image_url%> </p>
When I run my application and view a post it just says Image: with no image underneath it. UPDATE: I installed ImageMagick/GraphicsMagick, and when I go to save post it says: 1 error prohibited this post from being saved: Image Failed to manipulate with MiniMagick, maybe it is not an image? `Original Error: ImageMagick/GraphicsMagick is not installed`
and underneath it displays the image but it wont save the post. |
| Elasticsearch complex operators and analyzers Posted: 14 Dec 2016 03:36 AM PST I'm trying to create search by Candidates that includes nested models fields and should have breakwords. E.x: Candidate.search('candidate_requirement.location:(Lentimas AND Town) OR requisitions.requisition_number:45423', size: Candidate.count)
For now, when I do this search without 'AND' and 'OR', It breaks location: 'Lentimas Town' into 2 words 'Lentimas', 'Town', but I need it to be searched together. How to make that possible to search values divided by comma for example. Like: search('location:My Location, first_name:First Name')
Operator between args should be OR. Here is my trying: settings index: { analysis: { tokenizer: { comma: { type: 'pattern', pattern: ',' } }, analyzer: { comma: { type: :custom, tokenizer: 'comma', } } } } do mapping do indexes :requisitions do indexes :requisition_number, taype: 'string', analyzer: 'comma' end indexes :candidate_requirement do indexes :location, type: 'string', analyzer: 'comma' indexes :industry, type: 'string', analyzer: 'comma' end end end def as_indexed_json(_options = {}) as_json( only: [], include: { requisitions: { only: [:requisition_number] }, candidate_requirement: { only: [:location, :industry] } } ) end

| Rails: After creating a record (e.g. a user) update another table (e.g. not the users table)? Posted: 14 Dec 2016 04:26 AM PST In my application I have users and fake posts. What I want: For each user, the fake posts should be displayed in a random order - however the (fake) timestamp associated with the fake-posts should be chronological. To make it clearer: User A sees: - Post 1 created at 15.12.2016 - 14:00 - Post 2 created at 15.12.2016 - 13:00 - Post 3 created at 14.12.2016 - 23:00 User B sees: - Post 3 created at 15.12.2016 - 14:00 - Post 1 created at 15.12.2016 - 13:00 - Post 2 created at 14.12.2016 - 23:00
I have created a new table with those columns: fakepost_id | user_id | fake_timestamp
My models look something like this: # fakepost.rb class Fakepost < ApplicationRecord has_many :randomized end # user.rb class User < ApplicationRecord has_many :randomized end # randomized.rb class Randomized < ApplicationRecord belongs_to :user belongs_to :fakepost end
Now I want to do the following (I only have pseudocode by now because I have no idea how to implement it :(...) - When a new user is created...
- get all the fakeposts and...
- write into the new table for each fakepost: the fakepost_id, the user_id of the newly created user, and a random time in the past.
I know that in my user.rb model I can define an after_create callback, but how do I get all the fakeposts in my user model (they are not associated) and how do I write into another table (not the users table)? Or should I create a randomize.rb model? |
