| How to display params from a different Model within the /show of a different Model? Posted: 14 May 2016 07:13 AM PDT Working on an app in rails 4 that has Invoices and Clients as Models - I already set the associations between them as you can see in the snippets below from both Models, but can't achieve how to display for instance the Client.name within an Invoice show view. Through Rails console, if I do 'Invoice.last.client.name' - I can see the client name - but once I try to show that same thing in the view with this piece of code: <% @invoices.each do |invoice| %> <%= invoice.client.name %> <% end %>
I get this error undefined method `name' for nil:NilClass Invoice.rb (Model) class Invoice < ActiveRecord::Base belongs_to :client acts_as_schedulable :schedule # accepts_nested_attributes_for :clients end
Client.rb (Model) class Client < ActiveRecord::Base has_many :invoices validates_formatting_of :email, using: :email end
Tried adding doing something with nested attributes and adding the 'name' method in the Invoice controller, but don't know what I'm doing wrong. For more reference, I have included the whole Invoice controller in this pastebin link. def name @invoice = Invoice.client.name end

| Rails session is not changing value Posted: 14 May 2016 06:09 AM PDT consider the code below def results params_list = [] params.each_pair {|key, value| params_list.push([key,value]) } p params_list session.delete(:image) p session[:image] @image = Gchart.pie_3d(:size => '500x300', :title => "Top 5 Results", :legend => ["#{params_list[0][0]} #{params_list[0][1]}%" , 'source-document2 [22%]','source-document3','source-document4','source-document5'], :data => [22, 21, 20, 18, 19]) session[:image] = @image respond_to do |format| format.html { head 200, content_type: "text/html" } end end def check_results if session[:image] @image = session[:image] respond_to do |format| format.js end end end
as you can see i delete the session[:image] and then reassign it. But when call it from the check_results action, i get the very first session i stored. Why is that? |

| Is it advisable to use :foreign_key in my migrations rather than just adding user_id? Posted: 14 May 2016 06:14 AM PDT I am using rails 4.2, I just want to know if there would be any difference if I use the :foreign_key keyword in my migrations rather than just adding a user_id column to add relationship to my models ? |
| Annoying issue with Rails migration Posted: 14 May 2016 04:39 AM PDT Its not a problem but more like an annoying step which i have to repeat every time i made a mistake. I created a migration which like this: class CreateSubmissions < ActiveRecord::Migration def change create_table :submissions do |t| t.references :student, index: true, foreign_key: true t.references :assignment, index: true, foreign_key: true t.references :question, index: true, foreign_key: true t.text :code t.timestamps null: false end add_index :submissions, [:student_id, :assignment_id, :question_id], unique: true end end
try to rub rake db:migrate and it give me error that index name is too long and more, i change that line to this add_index :submissions, [:student_id, :assignment_id, :question_id], unique: true, name: 'index_submissions'
and again try to execute rake db:migrate at that time it give me error that submission_student_index already exists (because the first time it created the table but throw exception while adding index) i tried to rollback so that i can execute whole submissions table and index together but unfortunately it rollback my previous migration (in some cases a previous table or index or column). For that i have to manually go to the database and drop that submissions table and then execute rake db:migrate to create submissions table along with the all the index and also that previous migration. Its annoying to go back to the database and manually drop the table, i don't know if i am doing something wrong or there is some better way to this. |
| How to remove link name after is visited Posted: 14 May 2016 04:46 AM PDT I have and app with some question. My links are numbers 1,2,3 ect. Each of this link is a path to another question. I made that visited link changes color but that option is not good. It's not good because when I once open that link it show it in color which I set for visited link. But when I delete from DB that question and add new it has again number 1 as link and it is shown as visited. This is part of code where I have done that: <% @categories.each do |category| %> <div id=<%= "box#{category.id}" -%>> <h1><%= category.name %></h1> <% category.questions.each_with_index do |question, i| %> <ul class="question-list" style="display: inline;"> <li><%= link_to (i + 1), show_path(question_id: question.id) %></li> </ul> <% end %>
This part look like this. below each category are questions. Category 1 2 3 4 I do not want delete question from database. I only want to delete link. So if I open question with number 1 and when I go back I want that this number 1 as link disappear and then I will have like this. Category 2 3 4 Question: How to delete just link name after link is visited? |
| Rails, hooking into controllers Posted: 14 May 2016 05:43 AM PDT OK, here's my problem: I have a HomeController with an action, say index, that would render a landing page for my site. The site also has a bunch of other Controllers that implement actions for various other functionalities. I want a dynamic navigation bar on my home page and what I'm looking for is that HomeController#index goes to every other Controller in my app and calls a particular method that would return and object with link details, for example, HomeController#index would go to ContactController and call a method get_link which would return something like: {label: "Contact", url: "/contact"}
Similarly HomeController#index would try calling get_link on every other controller until it has collected an Array of link objects which could then be passed to the View to render navigation. I tried doing this through metaprogramming in Modules and using included hook method (getting my references from a Sitepoint tutorial). But that didn't work. Then I read somewhere that I may have to use ActiveSupport::Concern for ths kind of functionality, but I'm not sure how to go about it. I've worked on PHP CMS like Drupal and WordPress any they implement this using hooks, which is more-or-less what I'm looking for here. Any ideas? |
| Why is single table inheritance a bad design choice? Posted: 14 May 2016 04:40 AM PDT Whenever I see any discussion about single table inheritance it is generally seen to be a bad idea, due to the fact that it introduces a lot of columns in the table which will always be empty, depending on the row. In reading around on this subject I came across this post on stackoverflow: how to avoid polymorphic associations The answer suggested seems to introduce the exact thing that single table inheritance introduces (and is seen as a bad thing..), but it is the solution in this case? Surely the answer given to this question just introduces a lot of empty columns into the table? If it is perfectly fine to do this, and there is essentially no performance cost to doing it, why is STI better to be avoided? I had accepted that having a lot of empty columns would be a poor design choice, and if it is not, I don't understand why it isn't? |
| Set attributes when automatically building has_one child model Posted: 14 May 2016 03:58 AM PDT I'm attempting to automatically build a child model when its parent is created, as noted in this post. Say I have two models Person has_one :folder and I would like to create a folder when the person creates To do this I go into the Person model and (from the example above) do the following. has_one :folder before_create :build_default_folder private def build_default_folder build_folder true end
This makes sense, but say Profile had some attributes that I would like to set an attribute for Folder based on the Person's attributes. Like if the person has :person_name what should I do to set :folder_name as "[person_name]'s_Folder"? Thanks for any suggestions. |

| Devise :: Trouble registering with custom fields to sign_up form Posted: 14 May 2016 06:18 AM PDT I am building a Rails application and I have some issues while registering users with Devise (and ActiveAdmin).
To the original sign_up form, I added a custom username field and this one cause me troubles: sometime user can register other time it doesn't (a validation error is raised for the username permitted params whereas I specified in controller I was allowing it). Here is my user model: class User < ActiveRecord::Base validates :username, presence: true, uniqueness: { case_sensitive: false, scope: :provider }, if: proc { |u| u.new_record? || u.changed? } # other stuff here end
Here is what I have set up in my controller: class ApplicationController < ActionController::Base before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) << :username end end
When the validation error is raised for username, I guess it's because this code is never called and this is where I'm stuck. In development, I have to kill all ruby processes and then it work again for 3 or 4 registrations and then raise error again. So what's could be wrong with my code ??? Thanks for your help ! Edit:
I discovered when I make a modification to my ruby code it stop working (unit tests stop passing). Could it be a cache issue ? Edit 2: here are my development logs for sign_up when it fails 14:19:05 web.1 | [INFO ] POST "/admin" for 127.0.0.1 at 2016-05-14 14:19:05 +0200 14:19:05 web.1 | [DEBUG] Setting Load (0.6ms) SELECT `settings`.* FROM `settings` ORDER BY `settings`.`id` ASC LIMIT 1 14:19:05 web.1 | [DEBUG] Setting::Translation Load (0.8ms) SELECT `setting_translations`.* FROM `setting_translations` WHERE `setting_translations`.`setting_id` = 1 14:19:05 web.1 | [DEBUG] Category Load (0.8ms) SELECT `categories`.* FROM `categories` WHERE `categories`.`name` = 'LegalNotice' LIMIT 1 14:19:05 web.1 | [DEBUG] Menu Load (0.6ms) SELECT `menus`.* FROM `menus` WHERE `menus`.`id` IN (8) 14:19:05 web.1 | [DEBUG] Menu::Translation Load (0.6ms) SELECT `menu_translations`.* FROM `menu_translations` WHERE `menu_translations`.`menu_id` IN (8) 14:19:05 web.1 | [DEBUG] Category Load (0.6ms) SELECT `categories`.* FROM `categories` WHERE `categories`.`name` = 'Registration' LIMIT 1 14:19:05 web.1 | [DEBUG] OptionalModule Load (1.1ms) SELECT `optional_modules`.* FROM `optional_modules` ORDER BY `optional_modules`.`id` ASC LIMIT 1000 14:19:06 web.1 | [DEBUG] AdultSetting Load (0.6ms) SELECT `adult_settings`.* FROM `adult_settings` ORDER BY `adult_settings`.`id` ASC LIMIT 1 14:19:06 web.1 | [DEBUG] AdultSetting Load (0.4ms) SELECT `adult_settings`.* FROM `adult_settings` 14:19:06 web.1 | [DEBUG] AdultSetting::Translation Load (0.3ms) SELECT `adult_setting_translations`.* FROM `adult_setting_translations` WHERE `adult_setting_translations`.`adult_setting_id` = 1 14:19:06 web.1 | [DEBUG] Slider Load (0.4ms) SELECT `sliders`.* FROM `sliders` INNER JOIN `categories` ON `categories`.`id` = `sliders`.`category_id` WHERE `sliders`.`online` = 1 AND (categories.name = 'Registration') ORDER BY `sliders`.`id` ASC LIMIT 1 14:19:06 web.1 | [DEBUG] VideoSetting Load (0.3ms) SELECT `video_settings`.* FROM `video_settings` ORDER BY `video_settings`.`id` ASC LIMIT 1 14:19:06 web.1 | [DEBUG] (0.1ms) BEGIN 14:19:06 web.1 | [DEBUG] User Exists (0.6ms) SELECT 1 AS one FROM `users` WHERE `users`.`email` = BINARY 'demo22@demo.fr' LIMIT 1 14:19:06 web.1 | [DEBUG] User Exists (2.8ms) SELECT 1 AS one FROM `users` WHERE (`users`.`username` IS NULL AND `users`.`provider` IS NULL) LIMIT 1 14:19:06 web.1 | [DEBUG] User Exists (0.3ms) SELECT 1 AS one FROM `users` WHERE (`users`.`email` = 'demo22@demo.fr' AND `users`.`provider` IS NULL) LIMIT 1 14:19:06 web.1 | [DEBUG] (0.2ms) ROLLBACK 14:19:06 web.1 | [DEBUG] OptionalModule Load (0.4ms) SELECT `optional_modules`.* FROM `optional_modules` WHERE `optional_modules`.`name` = 'SocialConnect' LIMIT 1 14:19:06 web.1 | [DEBUG] SocialConnectSetting Load (0.2ms) SELECT `social_connect_settings`.* FROM `social_connect_settings` ORDER BY `social_connect_settings`.`id` ASC LIMIT 1 14:19:06 web.1 | [DEBUG] SocialProvider Load (0.3ms) SELECT `social_providers`.* FROM `social_providers` WHERE `social_providers`.`enabled` = 1 14:19:07 web.1 | [INFO ] method=POST path=/admin format=html controller=registrations action=create status=200 duration=1306.84 view=1185.47 db=11.72 unpermitted_params=["username"]

- Double checked that PayPal buyer account is a business pro account. But then no luck
Paypal account details Any other regular/possible mistakes that am making? Any help will be much appreciated. Thanks in advance. |

| Zurb Foundation's javascript not working Posted: 14 May 2016 05:43 AM PDT Currently working on Rails 4.2.6, installed foundation-rails gem, follow all the instruction. Now it include a bunch of javscript and stylesheet files in application, application.js //= require jquery //= require jquery.turbolinks //= require jquery_ujs //= require dataTables/jquery.dataTables //= require jquery_sortable //= require foundation //= require turbolinks //= require_tree . $(function(){ $(document).foundation(); });
but when i try to use some components having javascript in it, it does not work. I tried this drop-down from foundation's docs <a href="#" class="button" data-dropdown="drop">Link Dropdown »</a> <ul id="drop" class="[tiny small medium large content]f-dropdown" data-dropdown-content> <li><a href="#">This is a link</a></li> <li><a href="#">This is another</a></li> <li><a href="#">Yet another</a></li> </ul>
It just give me some links without any working drop-down and an error in console TypeError: Cannot read property 'className' of undefined(…) (anonymous function) @ foundation.core.self-f55f82f….js?body=1:197
Also alert messages are not working properly either, <div class="row"> <div class="small-6 small-centered columns"> <% flash.each do |name, msg| %> <% flag = name.to_s == 'notice' ? 'success' : 'alert' %> <div data-alert class="alert-box <%= flag %> radius"> <strong><%= flag == 'success' ? 'Yay!' : 'Error' %></strong> - <%= msg %> <a href="#" class="close">×</a> </div> <% end %> </div> </div>
It shows an alert box with message but it won't close by clicking on x button or link and for that it don't give any error messages. |

| Rails Active Record - Calling Distict Rows Posted: 13 May 2016 11:55 PM PDT I have the following models influencers (id, name, ..) influencer_authorizations (id, influencer_id, ... ) influencer_metrics (id, influencer_authorization_id, date, count)
The relationships are as follows influencers has_many influencer_authorizations influencer_authorizations has_many influencer_metrics
I want to fetch the count of all the influencer_authorizations in the influencer_metrics with the latest DATE and sum to show the total followers of the influencer What am trying Finding all the Authorizations IDs influencer_authorizations = InfluencerAuthorization.where(influencer_id: influencer.id).pluck(:id)
Now i am trying to find the latest Date's rows all the influencer_authorizations technically for each influencer_authorizations it should give back one row whose sum i want to calculate. total_followers = InfluencerMetric.where(influencer_authorization_id: influencer_authorizations).order('metrics_date DESC').first
But it returns all the rows right now. The date is tricky as i each influencer_authorizations last fetched date can be different at times. So we need the lastest metrics records for each influencer_authorizations |
