发出传递参数Form :: Open Laravel

Question

Fairly new at Laravel and trying to grasp the store function and routing. I'm getting the following error trying to open a form in Laravel:

Missing required parameters for [Route: {$route->getName()}] [URI: {$route->uri()}].

The issue is because my url is:

/projects/1/documents/create

And I'm opening to:

/projects/1/documents

I'm trying to pass the projects ID but I'm missing something.

Form Call:

{!! Form::open(['route'=>'projects.documents.store', $project->id]) !!}
     @include('pages.projects.documents.charter.partials._form', ['submitButtonText'=>'Create Project Charter'])
{!! Form::close() !!}

My Web Route (I'm assuming the issue is here):

// Resource route for Project Document Controller
Route::resource('projects.documents', 'Project\DocumentController');

My DocumentController store function:

public function store(Request $request, Project $project)
{
    // Validate the request
}

I'm not sure if there is any other sections of code that are need. The page renders fine without Form::open and $project->id echo's out correctly.

Edit:

I figured out my issue, it was somewhat silly. Just not use to Laravel formatting yet. The route & param needed to be in an array. The correct formatting is:

{!! Form::open(['route'=>array('projects.documents.store', $project->id)]) !!}
