Question

I have 3 models: Users, Customers, Issues. Below is the code for these models

Customer model:

class Customer < ActiveRecord::Base
  belongs_to :se
  belongs_to :user
  has_many :issues
end

Issues model:

class Issue < ActiveRecord::Base
  belongs_to :customer
end

Users model:

class User < ActiveRecord::Base
  has_many :ses
  has_many :customers
  has_many :issues, :through => :customers

  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  attr_accessible :email, :password, :password_confirmation, :remember_me, :first_name,     :last_name, :cell_ph, :area


end

I would like to display only the issues that belong to a particular user. I am having problems making this work. Can someone suggest how I might create an index method that would accomplish this?

Here is my index method where I’m trying to use devise’s current_user method to identify the user who’s logged in to the view:

  def index
    @issues = Issue.where(:user == :current_user)

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @issues }
    end
  end

You can’t do what you’re doing because an Issue doesn’t have a user.

According to Rails guides (second example on http://guides.rubyonrails.org/association_basics.html#the-has_many-through-association session), you can nest the has_many using a has_many :through.

So you should be able to do this:

current_user.issues
