UPDATE:

I needed to put my controller code ABOVE super, for example, and then I had access to the @company instance variable in the view:

User Registration Controller:

class UserRegistrationController < Devise::RegistrationsController
  before_action :configure_permitted_parameters
  skip_before_filter :load_customer_access, only: [:new, :create]  

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :current_password, :password, :password_confirmation, :email) }
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name, :last_name, :current_password, :password, :password_confirmation, :email) }
  end

  def edit
    @customer = current_user.customer
    @company = Company.find_by_domain(User.get_domain(@customer.email))          
    super          
  end
end

      

        
        
        
      

    

I want to pass the company id of the current user so that I can view all users from the same company.

This page will be accessed via a button on the Edit Account page (auto-generated view using Develop). This is the page where I am getting the following error:

Note. I only see this error using the User Management button. If I comment out this line and look at my logs, I can see it perfectly:

User model:

   ...
   def self.get_domain(email_address)
     email_address.gsub(/.+@([^.]+.+)/, '\1')
   end

  def confirm!
    current_customer = Customer.where(email: self.email).first        
    super
  end

  def ensure_has_customer
    customer = self.customer
    company = Company.find_by_domain(User.get_domain(self.email))
  end
  ...

      

        
        
        
      

    

User Registration Controller:

class UserRegistrationController < Devise::RegistrationsController
  before_action :configure_permitted_parameters
  skip_before_filter :load_customer_access, only: [:new, :create]  

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :current_password, :password, :password_confirmation, :email) }
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name, :last_name, :current_password, :password, :password_confirmation, :email) }
  end

  def edit
    super
      @customer = current_user.customer
      @company = Company.find_by_domain(User.get_domain(@customer.email))
      puts "HAPPY CUSTOMER"
      puts @customer.email    
      puts "HAPPY COMPANY"
      puts @company.id // See above screenshot for logs
  end
end

      

        
        
        
      

    

Change user route:

match "company/:company_id/edit_users" => 'company#edit_users', via: [:get], :as => :edit_company_users

The code for my controller and views can reach edit_company_users_path

ok, and the company controller code is shown below if useful:

Company controller:

class CompanyController < ApplicationController    

  def index
    @companies = Company.all
    respond_to do |format|
      format.html
      format.json { render json: @companies }
    end
  end   

  def edit_users
    @company = Company.find(params[:company_id])
    @company_name = @company.name
    @domain = @company.domain
    @find_domain = "%" + @domain + "%"
    @users = User.find(:all, :conditions => ["email LIKE ?", @find_domain])
  end
end

      

        
        
        
      

    

View company index

<div class="col-md-12">    
  <div class="row">
    <div class="col-md-2"></div>
      <div class="col-md-8">
        <div class="page-header">
          <h1>Manage Companies</h1>
        </div>
        <table class = "table table-striped table-bordered">
          <tr>
            <th>Company Name</th>
            <th>Domain</th>
            <th>Action</th>
          </tr>

          <% @companies.each do |company| %>
            <tr>
              <td><%= company.name %></td>
              <td><%= company.domain %></td>
              <td>
                <%= link_to 'Manage Company Access', edit_company_path(company), :class => 'btn btn-sm btn-default' %>
                <%= link_to 'Manage Applications', edit_company_applications_path(company), :class => 'btn btn-sm btn-default' %>
                <%= link_to 'Manage Users', edit_company_users_path(company), :class => 'btn btn-sm btn-default' %><br>
              </td>
            </tr>
          <% end %>
        </table>
      </div>      
    </div>
  </div>

      

        
        
        
      

    

It is interesting to note that when I do <%= @company %>

in the view, the Company name does not appear (although the ID is 2 and the name is "Ryan Drake") and is displayed in view mode. When I do <%= @company.id %>

, it throws out "undefined method" id "for nil: class".

Any guide to accessing the Company ID from the Edit Account view in the easiest way, so I can pass that through a parameter and hit the method would be excellent.
