| Rails: Read image source/remote_url and show image as my own image on my website Posted: 17 Sep 2016 07:45 AM PDT I need to do something similar to following in my rails app. Suppose there is an image on flickr. I need to read that image and show at my own website url. suppose image is at: http://www.flickr.com/some_image.jpg I need to show that image at http://my-website.com/some-image.jpg The user should not realize that it's coming from any other website. The output should be cached for future request. How do I do that in rails. thanks, |

| How do I use lookup_context to make this view as DRY as possible? Posted: 17 Sep 2016 05:16 AM PDT For starters, this is the view I am trying to replicate: 
This is the HTML from that layout (from the SAT portion anyway, you can extrapolate the rest): <table class="table table-hover table-bordered"> <thead> <td colspan="2" class="text-center"> <strong>SAT</strong> </td> <tr> <th>Subject</th> <th>Grade</th> </tr> </thead> <tbody> <tr> <td>Reading</td> <td>900</td> </tr> <tr> <td>Math</td> <td>700</td> </tr> <tr> <td>Writing</td> <td>800</td> </tr> <tr> <td><strong>Total</strong></td> <td><strong>2,400</strong></td> </tr> </tbody>
This is what my Grade.rb model looks like: # == Schema Information # # Table name: grades # # id :integer not null, primary key # subject :string # result :string # grade_type :integer # profile_id :integer # created_at :datetime not null # updated_at :datetime not null # class Grade < ActiveRecord::Base belongs_to :profile enum grade_type: { csec: 0, cape: 1, sat: 2, g7: 3, g8: 4, g9: 5, g10: 6, g11: 7, g12: 8, g13: 9 } end
This is what that table looks like currently, i.e. before using the lookup_context method in Rails: <table class="table table-hover table-bordered"> <thead> <td colspan="2" class="text-center"> <strong>SAT</strong> </td> <tr> <th>Subject</th> <th>Grade</th> </tr> </thead> <tbody> <% @sat_grades.each do |grade| %> <tr> <% if grade.subject.eql? "Total" %> <td><strong><%= grade.subject %></strong></td> <td><strong><%= grade.result %></strong></td> <% else %> <td><%= grade.subject %></td> <td><%= grade.result %></td> <% end %> </tr> <% end %> </tbody>
Where @sat_grades is this: @sat_grades = @profile.grades.where(grade_type: :sat). I want to use this lookup_context method, I was thinking like this: <% @grades.each do |grade| %> <% if lookup_context.template_exists?(grade.grade_type, "grades/grade_types", true) %> <%= render partial: "grade/grade_types/#{grade.grade_type}", locals: {event: event, index: index} %> <% end %> <% end %>
The issue I am running into is that each grade_type has a different table. So grade_type: :sat belongs in the "SAT" table, the same for "CSEC", "g11", etc. I can't think of a way to have each of those grade_types rendered specifically within their HTML table, without having lots of lookup_context.template_exists? calls within that view. It almost defeats the purpose of doing it like that, if I have to have a lookup_context call for each grade_type. What's the best way to approach this so I just have 1 lookup_context call (if possible), but it correctly renders and handles all the different grades correctly. |

| ActiveRecord many-to-many table with association type field - Rails Posted: 17 Sep 2016 06:25 AM PDT I'm building a Rails photo gallery app which allows users to create private galleries and invite users to the gallery under different permissions (i.e: viewer and editor). I am thinking that galleries_users table will be required to resolve the many-to-many relationsip: user_id | gallery_id -------------------- 1 | 4 -------------------- 2 | 4
But should I store the association permission type? Can I just add a permission field: user_id | gallery_id | permission --------------------------------- 1 | 4 | edit --------------------------------- 2 | 4 | view
Is this on the right track? I have also seen the Rolify gem but using that would mean adding a user to a project (via method above) and the adding a role separately through Rolify's interface. Unless there is a way I can skip the first step of adding a user to a gallery and treat the role as the association? |
| How to reverse a SUDO fix/ restore old file plan? Posted: 17 Sep 2016 04:48 AM PDT In trying to resolve this issue (which popped up out of nowhere and for which there were no obvious problems with capital letters): Strange error in rails - missing helper I (foolishly, I know) made use of one of the suggested solutions in the comments: I had the same problem, but NO user-created directories that had uppercase letter in them... only /Users. I tried upgrading to ruby 2.2.1 - this did not fix it. I very hesitantly fixed it by doing the same case-sensitive "fix" on my /Users directory: cd / sudo mv Users users1 sudo mv users1 users
I have yet to see if that breaks anything else.... For me, it has broken everything else. I now appear to have a 'Users/users1/derekbreslin' folder, where all my data is held (and which I appear unable to access through the terminal). This is in addition to a 'Users/derekbreslin' folder, which I assume is my original folder, but which is now essentially empty. My machine doesn't boot up as it used to either - I can use it, but the desktop is entirely clear and the machine thinks I'm opening most applications up for the first time now. More than anything, I'd like to just get my machine back to where it was - sadly I don't have time machine switched on for my Mac (I didn't realise you needed to..), so I'm casting around for help. In short, is there a way, perhaps using the terminal, to reverse the instructions above (and therefore the foolish damage that I've done)? All advice will be very gladly received! And apologies if this is the wrong place for such a request - more than happy to direct it elsewhere if need be. |

Why does rspec not pass defautl url option (locale) that I set in ApplicationController?And how can tell rspec to do this? |

| Custom actions using devise Posted: 17 Sep 2016 03:39 AM PDT Background: The Rails 4 application I am working on has differing logic for API and web registrations, and part of this logic makes their integration extremely difficult. To that end, I'm attempting to separate the routes to deal with issues arising from inheritance, new reCAPTCHA gem, and new logic. (both actions call registrations#create after their respective logic.) I've solved most of the issues arising from separating these two; however, getting the routes working has proven difficult as well. I'd greatly appreciate any help!
Desired Result: I'm trying to define a route to a custom action using Devise, and prevent it from creating the default route as well. I've gotten one of them working, but not the second. Here's the excerpt from my routes.rb: Registry::Application.routes.draw do devise_for :users, controllers: { passwords: 'users/passwords', sessions: 'users/sessions', registrations: 'users/registrations' } devise_scope :user_registration do post 'users', to: 'users/registrations#custom_one' end # ... namespace :api do namespace :v1 do # ... devise_scope :user do post 'users', to: 'registrations#custom_two' end end end end
Issues: The issue is that this code generates two nearly-identical routes. Excerpt from rake routes: user_registration POST /users(.:format) users/registrations#create users POST /users(.:format) users/registrations#custom_one api_v1_users POST /api/v1/users(.:format) api/v1/registrations#custom_two
I also want the custom route to have the correct prefix/route name (user_registration), though I've been unable to do this. I've found plenty of documentation on custom names for Devise routes, but not for custom actions. Especially not when using devise_for.
To summarize: - I need to disable the default
users/registrations#create route - and specify a route to a custom action (
users/registrations#custom_one) - with the correct prefix/name (
user_registration) hopefully as elegantly as possible, as I would rather avoid specifying each route independently. |

| How to convert a multi-key hash to single key hash in Ruby for Highcharts Posted: 17 Sep 2016 03:30 AM PDT I have this data in Ruby, for creating a barchart using Highcharts.js which requires the data in a JSON format: data = {["January", "a"]=>54, ["January", "b"]=>13, ["January", "d"]=>2, ["January", "c"]=>1, ["February", "a"]=>27, ["February", "b"]=>11, ["February", "c"]=>4, ["March", "a"]=>22, ["March", "b"]=>11, ["March", "d"]=>2, ["March", "c"]=>2, ["April", "a"]=>32, ["April", "b"]=>12, ["April", "d"]=>6, ["April", "c"]=>2, ["May", "a"]=>7, ["May", "d"]=>3, ["June", "a"]=>5, ["July", "a"]=>25, ["August", "a"]=>23, ["August", "d"]=>3, ["August", "c"]=>3, ["September", "a"]=>6}
The data is stored in a variable and is not coming from a file. I want to convert this into a json object to send it to Highcharts for charting. I need the data in the following format: category = ["January","February","March","April","May","June","July","August","September"] series: [{ name: 'a', data: [54, 27, 22, 32, 7, 5, 25, 23, 6] }, { name: 'b', data: [13, 11, 11, 12, 6, 0, 0, 0, 6] }, { name: 'c', data: [1, 4, 0, 2, 0, 0, 0, 3, 6] }, { name: 'd', data: [2, 0, 0, 6, 3, 0, 0, 3, 6] }]
The data is missing for some months, and sometimes not in alphabetical order. Is there an easy way in Ruby to unlist the original Hash, and then extract the information out of it while filling the missing values with 0, and getting the JSON output as required? p.s. :Tried converting the data.to_json but highcharts doesnt accept it in raw form. Is there any other way to create a bar chart using this data in Highcharts? |
| Capistrano doesn't create puma.pid file Posted: 17 Sep 2016 02:49 AM PDT I use Capistrano to deploy my Rails app. However, when I deploy my application, puma.pid file is not being created, which leads to a problem - I can't restart server or deploy new version with capistrano - capistrano fails to stop puma, because puma.pid don't exests and it assumes no puma processes is running. And I get ADDRESS ALREADY IN USE error when capistrano tries to run another version of puma. Here is my deploy.rb lock '3.4.0' set :application, 'appname' set :repo_url, 'giturl' set :deploy_to, '/home/user/appname' set :pty, false set :linked_files, %w(config/application.yml config/database.yml) set :linked_dirs, %w(log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system public/uploads) set :keep_releases, 5 set :rvm_type, :user set :rvm_ruby_version, '2.3.0' set :puma_rackup, -> { File.join(current_path, 'config.ru') } set :puma_state, "#{shared_path}/tmp/pids/puma.state" set :puma_pid, "#{shared_path}/tmp/pids/puma.pid" set :puma_bind, "unix://#{shared_path}/tmp/sockets/puma.sock" # accept array for multi-bind set :puma_conf, "#{shared_path}/config/puma.rb" set :puma_access_log, "#{shared_path}/log/puma_error.log" set :puma_error_log, "#{shared_path}/log/puma_access.log" set :puma_role, :app set :puma_env, fetch(:rack_env, fetch(:rails_env, 'production')) set :puma_threads, 1 set :puma_workers, 1 set :puma_worker_timeout, nil set :puma_init_active_record, true set :puma_preload_app, true set :sidekiq_config, 'config/sidekiq.yml' set :sidekiq_log, '/dev/null' set :sidekiq_processes, 1 set :clockwork_file, "clock.rb" namespace :deploy do desc 'Recompile all enterprise themes' task :recompile_themes, [:command] => 'deploy:set_rails_env' do |task, args| on primary(:app) do within current_path do with :rails_env => fetch(:rails_env) do rake 'themes:recompile' end end end end after :finishing, "deploy:recompile_themes" end require 'appsignal/capistrano'
And when I try to stop running Puma, for example, I get the following error: ... DEBUG [37113fcf] Running [ -f /home/user/appname/shared/tmp/pids/puma.pid ] as user@server DEBUG [37113fcf] Command: [ -f /home/user/appname/shared/tmp/pids/puma.pid ] DEBUG [37113fcf] Finished in 0.273 seconds with exit status 1 (failed). WARN Puma not running
And indeed, /home/user/appname/shared/tmp/pids/puma.pid file don't exists. Do I need to create it manually or something? sidekiq.pid that is also being created the same way can be found in the same directory, so I don't think it's a permissions issue. Any advices on how to approach this? |

| Encrypt String to database and file saved Posted: 17 Sep 2016 01:00 AM PDT Guess I'm digging around the internet to learn about security and how to explain to users that their information is kept safe; we all know nothing is safe. I use an API that needs a consumer key/secret and a privatekey.pem file, in total three "items". These are the two questions: - How to store these consumer keys on a postgres db?
- Where to upload a privatekey.pem file?
For number 2, I've been reading here. I could not ask question there as this relates to Ruby on Rails; I am using Ruby on Rails 5 here. Could I simply store the consumer keys as normal sting type in the database and use Paperclip to upload to aws (encrypted)? These consumer key/secret and .pem file are from users. I think I may need to "password-save" those consumer strings. |
| Query returns record in Rails console but Model resulting in 500 Internal Server Error Posted: 17 Sep 2016 05:28 AM PDT Context - I am creating a quiz app to learn rails.

| Rails 4 many-to-many querying both ways Posted: 17 Sep 2016 06:06 AM PDT I have a many-to-many relationship between two models - Teams and Tournaments. When I query to get teams participation in a tournament by calling @tournament.teams i get the expected results. When I'm trying it the other way around by calling @team.tournaments, to get a list of tournaments in which the team is participation I'm getting the following error: Mysql2::Error: Unknown column 'tournaments.team_id' in 'where clause': SELECT `tournaments`.* FROM `tournaments` WHERE `tournaments`.`team_id` = 2
How can I make this work? I suppose it's a simple fix, but I'm just a beginner and can't seem to figure it out myself. EDIT: Team model: class Team < ActiveRecord::Base has_many :user_teams has_many :users, :through => :user_teams has_many :teams_in_tournaments has_many :tournaments, :through => :teams_in_tournaments has_many :tournaments belongs_to :team_leader, class_name: "User" has_many :matches end
Tournament model: class Tournament < ActiveRecord::Base has_many :teams_in_tournaments has_many :teams, :through => :teams_in_tournaments belongs_to :organizer, class_name: "User" has_one :rule, :dependent => :destroy accepts_nested_attributes_for :rule has_many :matches, :dependent => :destroy belongs_to :winner, class_name: "Team" end

| Rails: How to filter table records during a period? Posted: 16 Sep 2016 11:54 PM PDT model Express has an attribute "date"
In the Index page, I hope to filter out express information during a period, what technology can be used here?
I searched railscast 240 "Search, Sort, Paginate with AJAX", but it did cover this.
what I want basically like this. When the first time index page is loaded no record shows,until I set a period and click search button it will show records.

| Unable to set cookies in rails [duplicate] Posted: 16 Sep 2016 09:25 PM PDT This question is an exact duplicate of: LoginController: class LoginController < ApplicationController def new cookies[:time]=Time.now render "login" end def auth if params[:name].present? && params[:pass].present? @name=params[:name] pass=params[:pass] if( @name == "admin" && pass == "admin" ) cookies[:time] = Time.now render "success" else render "authfailed" end else render "argerror" end end end
login.html.erb: <body> <center> <h1> Login </h1> <form action='login/auth' method='POST'> Name: <input type="text" name="name" width=20><br> Password: <input type="password" name="pass" width=20><br> <input type="submit" value="submit"> </form> </center> <br><br> </body>
In the above scenario, the cookies stored in auth action is not set in client browser. To check that what I do is, when the user calls "login/new", then the login page is rendered to the browser. So, at that time I set the cookie. Here it is properly worked. But when the user submitted the entered data to "login/auth" action, it is not worked. I need to set the cookie only when the username and password is "admin". So I set the cookie within "if" condition. But it is not worked. But it successfully renders the "success.html.erb" page. So why the cookies is not set in "success.html.erb" page. Is there any error in my code ? |
| Understanding Security and Secret Keys Posted: 16 Sep 2016 09:37 PM PDT I am making a Rails application and am trying to understand security as it involves secret keys. My project uses Rails 5 and the Devise gem. I read in several places that you don't want to put files like secrets.yml onto github for security reasons (which I discovered several commits down the road). However, my secret keys that are used in production are environment variables (although my development and keys are not, they can be seen). What I am trying to figure out now, is that is it fine that files like secrets.yml (I also heard some things about database.yml as well), have ended up on github, as long as the important bits (like secret keys) are environment variables, which fortunately Rails seems to have thought of by default? Or should I go through the effort of removing those files? |

| Why can't I query my ActiveRecord CollectionProxy? Posted: 16 Sep 2016 08:16 PM PDT I have a form object that builds nested children @billing_items = build_billing_items def build_billing_items @billable_items.each do |item| @billing.billing_items.find_or_initialize_by(item_id: item.id).tap do |billing_item| billing_item.amount = item.amount end end @billing.billing_items end
Then in my attribute writer I try to find or initialize my child records vs my form params.. def billing_items_attributes=(params) params.each do |_i, hash| @billing_items.find_or_initialize_by(item_id: hash[:item_id].to_i).tap do |b| b.amount = hash[:amount] end end end
At this point I could not use find_or_initialize on @billing_items. I did some tinkering an found out that @billing_items at this point is of type ActiveRecord_Associations_CollectionProxy which does not have query methods where or find_by. Is there another more ActiveRecord way to query @billing_items other than using the ruby detect or select? Is there a way for me to avoid ending up with an ActiveRecord_Associations_CollectionProxy? Or from a form object perspective, can I do something better to avoid having to find_or_initialize_by in my attribute writer? |
