Getting MethodNotAllowedException using laravel 5

Hi I'm new to Laravel and im following the laracasts on view partials and form reuse.

I am getting to an edit page fine. The html looks like this:

@extends('app')

@section('content')
<h1>Edit: {!! $edu_content->title !!} </h1>

{!! Form::model($edu_content, ['method' => 'PATCH', 'url' => 'edu_contents/' . $edu_content->id ]) !!}
<div class="form-group">
    {!! Form::label('title', 'Title:') !!}
    {!! Form::text('title', null, ['class' => 'form-control']) !!}
</div>

<div class="form-group">
    {!! Form::label('tags', 'Tags:') !!}
    {!! Form::text('tags', null, ['class' => 'form-control']) !!}
</div>

<div class="form-group">
    {!! Form::label('user_id', 'User ID:') !!}
    {!! Form::text('user_id', null, ['class' => 'form-control']) !!}
</div>

<div class="form-group">
    {!! Form::label('location', 'Location:') !!}
    {!! Form::text('location', null, ['class' => 'form-control']) !!}
</div>

<div class="form-group">
    {!! Form::label('file_size', 'File Size:') !!}
    {!! Form::text('file_size', null, ['class' => 'form-control']) !!}
</div>

<div class="form-group">
    {!! Form::label('uploaded_at', 'Created On:') !!}
    {!! Form::input('date','uploaded_at', date('Y-m-d'), ['class' => 'form-control']) !!}
</div>

<div class="form-group">
    {!! Form::submit('Add Edu content!', ['class' => 'btn btn-primary form-control']) !!}

</div>
{!! Form::close() !!}

@if ($errors->any())
<ul class="alert alert-danger">
    @foreach ($errors->all() as $error)
    <li>{{ $error }}</li>
    @endforeach

</ul>
@endif

@stop

When I view the page source, however, it says action="http://localhost/edu_contents" rather than action="http://localhost/edu_contents/5" like it should.

Then when I submit the form to update I get:

 MethodNotAllowedHttpException in RouteCollection.php line 201:

Can anyone explain the error and why the id does not show up in the action?

My routes looks like Route::resource('edu_contents','EduContentsController');
