Laravel4: delete a comment - php

Question

I have a simple blog with Post resource and Comment nested resource.
Until now I can see all the comments belonging to a post and create a new comment for a post.
I want to give the possibility to delete a specific comment, but somehow I am making some mistakes.
This is the view comments.index with all the comments:
#extends('master')
#section('blog')
#foreach($comments as $comment)
<div class="span11 well">
<ul>
<li><strong>Body: </strong> {{ $comment->body }} </li>
<li><strong>Author: </strong> {{ $comment->author }}</li>
</ul>
{{ Form::open(array('method' => 'DELETE', 'route' => array('posts.comments.destroy', $post_id), $comment->id)) }}
{{ Form::submit('Delete', array('class' => 'btn btn-danger')) }}
{{ Form::close() }}
</div>
#endforeach
{{ link_to_route('posts.index', 'Back to Post index') }}
This is the error i get running the index: Parameter "comments" for route "posts.comments.destroy" must match "[^/]++" ("" given) to generate a corresponding URL.
This is the Index method inside CommentsController:
public function index($post_id)
{
$comments = Post::find($post_id)->comments;
return View::make('comments.index', compact('comments'))->with('post_id', $post_id);
}
And this is the Destroy method inside CommentsController:
public function destroy($post_id, $comment_id)
{
$comment = $this->comment->find($comment_id)->delete();
return Redirect::route('posts.comments.index', $post_id);
}
Someone can tell me please where I am making the mistake?
This the routes:
Route::resource('posts', 'PostsController');
Route::resource('posts.comments', 'CommentsController');

Answer 1

You have put a regexp tester on your route, to check your comments parameter.
This error message says that parameter that you give to Laravel isn't good.
If your parameter is only a decimal id, use \d+ regexp instead.

Answer 2

Without your routes.php file - I cant be sure, but I think this might be the problem.
Change
{{ Form::open(array('method' => 'DELETE', 'route' => array('post.comments.destroy', $post_id), $comment->id)) }
to
{{ Form::open(array('method' => 'DELETE', 'route' => array('post.comments.destroy', array ($post_id, $comment->id))) }
If this does not work - please post your routes.php file.
Edit: You have defined your route as a "resource". This means your destroy route is defined with only one variable. You dont actually need the $post included, so just define this:
{{ Form::open(array('method' => 'DELETE', 'route' => array('posts.comments.destroy', $comment->id))) }}
and change your destroy method to this - there is no need for the $post to delete a $comment:
public function destroy($comment_id)
{
$comment = $this->comment->find($comment_id)->delete();
return Redirect::back();
}
