Question

In the project management app I’m working on, I’m currently working on a page for managing tickets, which I want should contain of the following:

- The tickets that the user has created
- The tickets that belongs to projects that the user has created

The tricky part is to use the right code in the controller, which is where I need help.
‘@users_tickets’works fine, as well as ‘@owned_projects’. However, the last thing which is creating an array that contains of the tickets that belongs projects that the user owns, is something I need help me (yes, I understand that my poor try with an each loop is totally the wrong way to go here).

How can I achieve what I want?

Tickets controller:

1.    def manage
2.      @users_tickets = Ticket.where(:user_id => current_user.id)
3.      @owned_projects = Project.where(:user_id => current_user)
4.
5.      @owned_projects.each do |project|
6.          @tickets_for_owned_projects = Ticket.where(:project_id => project.id)
7.      end
8.    end

Tables:

tickets table:

project_id
ticket_status_id
user_id
title
description
start_date
end_date

projects table:

user_id
title
description
start_date
end_date

If you’re using a has_many association, then it should as simple as

class User < ActiveRecord::Base
  has_many :projects
  has_many :tickets
  has_many :project_tickets, through: :projects, class_name: 'Ticket', source: :tickets
  #...
end

class Project < ActiveRecord::Base
  has_many :tickets
  #...
end

# in tickets controller
def manage
  @tickets = current_user.tickets
  @tickets_for_owned_projects = current_user.project_tickets
end

UPD: The approach above should work. I’m literally falling asleep right now and can’t define what is wrong here. Would really appreciate if someone looked into it.

Here’s another way around though.

class User < ActiveRecord::Base
  has_many :projects
  has_many :tickets  

  def project_tickets
    result = []  
    self.projects.each do |project|
      result << project.tickets
    end
    result.flatten
  end
  #...
end
