| date_select in rails , How do I get the selected value? Posted: 28 Dec 2016 07:23 AM PST My view file is below. <div class="field"> <%= f.label :deadline , class:"form-label" %><br /> <%= f.date_select( :deadline , use_month_numbers: true , start_year: (Time.now.year) , end_year: (Time.now.year+1) , start_month: (Time.now.month) , end_month: (12) , start_day: (Time.now.day) , end_day: (days_in_month(Time.now.month)) , default: Date.new(Time.now.year , Time.now.month , Time.now.day) , date_separator: '/' ) %> </div>
days_in_month(Time.now.month) is helper method. def days_in_month(month, year = Time.now.year) common_year_days_in_month = [nil, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31] return 29 if month == 2 && Date.gregorian_leap?(year) common_year_days_in_month[month] end
In this case , when user selects 'month', 'day' doesn't change. For example, in 2016-12-28, The page shows 2016/12/28 in default, and the end_day is 31 because 12 month has 31 days. But although user selects 11 month , end_day is 31 because 12 month has 31 days. in the case , I want to show 30 in end_day. Please help me... |
| How to render a js.erb with the same name as a member action in Rails? Posted: 28 Dec 2016 07:09 AM PST I'd think this would go automatically, as I have already managed to do so for my destroy action, but no JS in activated. My controller action looks like this: def visability_toggle @picture = Picture.find(params[:id]) @picture.toggle! :visable respond_to do |format| format.js { render :action => 'visability_toggle' } end end
And for now my pictures/_visability_toggle.js.erb that I would like to match my controller looks like this: alert('Picture id: #{@picture.id}');
The action itself works. Also this JS is correct and worked when I added it with render js: ... in the controller action. |
| Variables are global with SASS but not SCSS Posted: 28 Dec 2016 06:53 AM PST I have my application.css.scss set like this: @import "base/variables"; @import "./application/application";
Like the documentation says I am not using Sprockets' directives (require, require_tree, and require_self) at all so I expect my variables defined inside of base/_variables.scss to be globals and available for my /application/application.scss file but it's not the case: #content { margin-top: $big; }
Will return the error Undefined variable: "$big". I've tried the same thing with SASS by naming by files application.css.sass and /application/application.sass and while the variables now do seems to be globals I'll like to keep using the SCSS syntax, I've tried that by setting config.sass.preferred_syntax = :scss but I'm still being asked for Sass. Of course I could just import my variables file everytime I need my variables but that would go against the DRY principle. Is that possible to use the SCSS syntax while making my variables globally available? What am I missing here? Thanks in advance. |

| Filter eager-loaded has_many association Posted: 28 Dec 2016 05:14 AM PST Suppose I have the following two classes: class Group has_many :actions end class Action belongs_to :group belongs_to :user end
And I want to retrieve all Groups with their Actions, i.e. : Group.includes(:actions)
But I want to filter the loaded actions by the current user's user_id, so when iterating the 'actions' association, only the user's Actions would be returned. I could add another association, like so: has_many :current_user_actions, -> {where(user_id: User.current_user.id)}, class_name: 'Action'
But the aforementioned Group query feeds a view that iterates over the 'actions' (and not 'current_user_actions') association, so that option's ruled out. |
| Generate elements with jQuery and Rails Posted: 28 Dec 2016 04:45 AM PST I am not sure how to do that. I have a model Post which I am showing when somebody hits /posts/1. Now this post belongs to someone. Which means I have another model called User. But there is more. Now a post can have a Comment. All of this works fine so far, because I am just loading everything as soon as somebody hits /posts/1. Now I would like to show all posts from the user when somebody hits /users/1. I created a view called posts/_post.html.erb and in the view of the user I have this code snippet: <%= render @posts %>. This works so far! But now I would like to show comments of every post BUT only if he hits a button called Show comments. Now this should trigger an ajax call and then show my comments. My question here is, should I create a GET-Route where I get all of the comments from the post as JSON and then create the HTML-Elements with Javascript or is there a better version with Rails, because I already have a view called comments/_comments.html.erb? Do I really have to defined the template once in the view file and once in the Javascript? |
| How to handle error in event machine using transitions gem on rails? Posted: 28 Dec 2016 04:42 AM PST I am working on event machine (transitions gem) in rails 4.2 , I wrote a method named send_data and when state changed from pending to deliver, the send_data will be fired. def send_data data = { 'remote_id' => order.remote_id, 'items' => order.line_items } SendLineItemsToWebshop.call(data) end
SendLineItemsToWebshop is an another class which calls call method and waiting for some response, if response come , then event will be fired(state will be changed) , otherwise, state will be same.
require 'bunny' require 'thread' class SendLineItemsToWebshop def self.call(data) conn = Bunny.new(automatically_recover: false) conn.start channel = conn.create_channel response = call_client(channel, data) channel.queue(ENV['BLISS_RPC_QUEUE_NAME']).pop channel.close conn.close self.response(response) end def self.call_client(channel, data) client = RpcClient.new(channel, ENV['BLISS_RPC_QUEUE_NAME']) client.call(data) end def self.response(response) return response JSON.parse response end end
But problem is that when event deliver is called, it does not check send_data's response comes or not, it changes the state. Here is me deliver event: event :deliver do transitions :to => :delivered, :from => [:editing, :pending] , on_transition: [ :send_data ] end
But I want that if response is false or nil, transition state will not be changed. State will be changed only when response comes true. Please help me about this issue. |

| Populate join table using seeds.rb Posted: 28 Dec 2016 04:21 AM PST In my rails app I have three tables: users, roles, and users_roles. In my seeds.rb file I have the following ruby code: # create super admin role Role.create!([{name: "Super Admin", description: "Super Admin (can do anything)"}]) # create user User.create!([{name: "Cameron", email: "cameron.drysdale@example.com", password_digest: "$2a$10$k4FPOZlVmy.hIM5z1scFYeFc8cNcVGpq..MU0529LlSGylEqYLaqC"}]) # make user super admin User::HABTM_Roles.create!([{user_id: 1, role_id: 1}])
However it fails on that last line: User::HABTM_Roles.create! How do I add the data into the join table? |
| adding two factor authentication to devise Posted: 28 Dec 2016 03:59 AM PST I tried to add two-factor-authentication to my rails-app with this gem: https://github.com/tinfoil/devise-two-factor I used It like the example in the README. But I made a little bit more changes like this: application_controller: before_action :check_for_user_2fa protected def check_for_user_2fa if self.controller_name != "registrations" && self.action_name != "confirm_two_factor" return unless current_user && current_user.otp_required_for_login? redirect_to confirm_two_factor_url, alert: "You did not confirmed your two factor authentication." end end
to display the QRCode I use this script: def google_authenticator_qrcode(user) issuer = 'UB' label = "#{issuer}:#{user.email}" data = user.otp_provisioning_uri(label, issuer: issuer) url = "https://chart.googleapis.com/chart?chs=200x200&chld=M|0&cht=qr&chl=#{data}" return image_tag(url, :alt => 'Google Authenticator QRCode') end
In my routes.rb I added this: devise_scope :user do get '/users/two_factor/confirm' => 'users/registrations#confirm_two_factor', as: :confirm_two_factor put '/users/two_factor' => 'users/registrations#confirm_two_factor_update', as: :confirm_two_factor_update end
and the view to handle the auth after login: = google_authenticator_qrcode(resource) %h2 Hi, scan Google Authenticator QR code and enter result code below to confirm your two factor auth! = form_tag(confirm_two_factor_update_path, :method => :put) do = devise_error_messages! = text_field_tag :code = submit_tag "Log in!" = link_to "Sign out", destroy_user_session_path, :method => :delete
the QRCode is the right. But how can I check the right code? And how to skip the two-factor-auth for other controller? |

| Rspec inclusions like "-t visual" no longer working Posted: 28 Dec 2016 03:16 AM PST I am using Rails 4 and rspec-rails (3.4.2) and gems: gem 'selenium-webdriver', '2.45.0' gem 'capybara'
And I wanted to add an additional parameter -t visual to my rspec test like: rspec spec/feature/profile_spec.rb -t visual
So it could open a firefox for that, but in the rspec_helper.rb I used to be able to set a check like this: if config.filter_manager.inclusions[:visual] # Set my driver etc. config.filter_manager.inclusions.delete(:visual) else # Something else end
But the check config.filter_manager.inclusions[:visual] now returns nil, and I remember it was returning true in some of my previous apps that I have tried to build. Why inclusions are no longer detected, and how to fix this? |
| How to add conditional has_many associations Posted: 28 Dec 2016 06:35 AM PST I have following DB structure tasks id name parent_id 1 Abc nil 2 Pqr 1
comments id task_id body 1 1 This is sample comment 2 1 This is another sample comment
task.rb has_many :comments
comment.rb belongs_to :task
My requirement is to have an associations such that for the parent as well as children i should get the parent comments i.e. for both the above tasks i should get ['This is sample comment', 'This is another sample comment'] as child tasks will not have any comments. I tried something like following but it doesn't work task.rb has_many :comments, -> (o) { where(comments: {task_id: [o.id, o.parent_id]}) }

| Unexpected <tr> when looping Posted: 28 Dec 2016 05:49 AM PST I have an array of arrays @iterated_orders like this: [[1, "Don", 3], [nil, nil, 4], [2, "Vri", nil]]
And code in my view like this: %table - @iterated_orders.each do |day, day_name, order_id| - unless day.blank? %tr %td.day= day %td= order_id
I would expect it to output this html: <tr> <td class="day">1 Don</td> <td>3</td> <td>4</td> </tr> <tr> <td class="day">2 Vri</td> <td></td> <td></td> </tr>
But it outputs this HTML: <tr> <td class="day">1 Don</td> <td></td> </tr> <tr> <td>3</td> <td>4</td> </tr> <tr> <td class="day">2 Vri</td> <td></td> </tr> <tr> <td></td> </tr>
Why is there an extra <tr> and is the <td> with the order_id not added to the existing <tr>? |

| Bootstrap navbar collapse a links with exception not floating left Posted: 28 Dec 2016 03:37 AM PST Hello I want to make a float none in my application scss for all the a href from the navbar with the exception of the navbar-brand which is the "Home". This is my application.html.erb: <nav class="navbar navbar-default navbar-custom"> <div class="container"> <%= link_to "Home", root_path, class: "navbar-brand" %> <button class="navbar-toggle" data-toggle= "collapse" data-target=".navHeaderCollapse" > <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <div class="collapse navbar-collapse navHeaderCollapse" > <ul class="nav navbar-nav" id="top"> <li><%= link_to "Products", products_path %></li> <li><%= link_to "About the website", about_path %></li> </ul> <ul class="nav navbar-nav navbar-right"> <!-- the pull-right is like a float right --> <% if user_signed_in? %> <li><a><span class="current_user"> Current user: <%= @username %> </span></a></li> <li><%= link_to "Sign out", destroy_user_session_path, method: :delete %></li> <% else %> <li><a class="nav-link" data-toggle="modal" data-target="#login-modal">Log in</a></li> <li><a class="nav-link" data-toggle="modal" data-target="#signup-modal">Sign up</a></li> <% end %> </ul> </div> </div> </nav>
And this is my application.scss: @media (max-width: 769px) { #top{ padding-top: 40px; } } @media (max-width: 769px) { a:not(.navbar-brand){ padding-top: 40px; float: none!important; } }
The thing is that if I type: @media (max-width: 769px) { a{ padding-top: 40px; float: none!important; } }
It does what I want, by putting float none it works like kind of float left aligning all the a href to the left. BUT, as I said, I don't want it to do the same with the Home a href that has the class navbar-brand. That's the reason why I've tried with no success the a:not(.navbar-brand). |

| RoR - Validate string on website, no error Posted: 28 Dec 2016 02:39 AM PST In my Ruby on Rails app I have build a function to validate if a piece of javascript is added to a certain website. When I run this code I don't get any errors in my log, but my app says: We're sorry, but something went wrong. If you are the application owner check the logs for more information. But when I check the logs I don't see any errors. The code I have used is the following: def validate_installation data = HTTParty.get(self.website) url = "http://www.smartnotif.com/sn.js" if data.body.include? url return true else return false end end
When I run this code on my local development machine it runs fine, but when I try to runs this production machine on DigitalOcean I have this problem with the same code, no errors. |
