Printing tasks per task list with Laravel 4 Eloquent - laravel

Question

I'm trying to display several task lists in one page with their respective tasks. In my controller I'm using the following:
public function index()
{
$tasks_lists = Task_List::all();
$tasks = Task_List::find(1)->tasks;
return View::make('tasks.index', array(
'tasks' => $tasks,
'tasks_lists' => $tasks_lists
));
}
Using
$tasks = Task_List::find(1)->tasks;
Will return for all tasks lists the tasks appointed to task list 1. So I'm guessing here is my problem, what type of clause should I be using to achieve my goal?
My foreach in my view:
#foreach ($tasks_lists as $task_list)
<h2>{{ $task_list->title }}</h2>
<ul>
#foreach ($tasks as $task)
<li>
{{ Form::open() }}
<input type="checkbox" name="task" value="{{ $task->id }}" />{{ $task->name }}
{{ Form::close() }}
</li>
#endforeach
</ul>
#endforeach

Answer 1

Instead of fetching the tasks for one of the Task_List models (in your case the one with id 1) you should get them for every task_list.
Do this in your view:
#foreach ($tasks_lists as $task_list)
<h2>{{ $task_list->title }}</h2>
<ul>
#foreach ($task_list->tasks as $task)
{{-- etc --}
#endforeach
</ul>
#endforeach
Attention: if you leave it that way it will make a query on the db every time you call ->tasks. You need to use eager loading. This is done by adding with('relationship-name')
$tasks_lists = Task_List::with('tasks')->get();
return View::make('tasks.index', array(
'tasks_lists' => $tasks_lists
));

You don't need to look for the tasks in the controller, so that can be simply removed:
public function index()
{
$tasks_lists = Task_List::all();
$tasks = Task_List::find(1)->tasks;
return View::make('tasks.index', array(
'tasks' => $tasks,
'tasks_lists' => $tasks_lists
));
}
Then, you'll need to get the tasks for each task list in the view, like this:
#foreach ($tasks_lists as $task_list)
<h2>{{ $task_list->title }}</h2>
<ul>
#foreach ($task_list->tasks as $task)
<li>
{{ Form::open() }}
<input type="checkbox" name="task" value="{{ $task->id }}" />{{ $task->name }}
{{ Form::close() }}
</li>
#endforeach
</ul>
#endforeach
And that should be enough. :)
