Hi, I create a Project, then within this project I can create different Documents. I have a generic documents table and a document data table. The document data table store the key (input label) and value (input). Doing it this way, I can create any documents I want, all I need to do is create a new view for a new document. To give you an idea, my database might look like

project

 id | projectName  | 
------------------
 1  | Project One  | 
------------------

document

 id | projectId  | documentName |
--------------------------------
 1  | 1          | DocumentA    |
--------------------------------


document_data

 id | documentId | key         |  value      |  
----------------------------------------------
 1  | 1          | clientName  |  Google     |   
----------------------------------------------
 2  | 1          | projectName |  Analytics  |  
----------------------------------------------
 3  | 1          | Contact     |  Mr Sharp   |  
----------------------------------------------
 4  | 1          | startDate   |  29/12/2016 |  
----------------------------------------------

The create views form is linked to my Document model

{!! Form::model(new App\Document, [
	'class'=>'form-horizontal',
	'route' => ['projects.documents.store', $project->id]
]) !!}

In my store function I do

$document = new Document();
$document->projectId = $project->id;
$document->name = Input::get('documentType');
$document->description = Input::get('documentTypeDesc');
$document->save();

$input = $request->all();

foreach($input as $key => $value) {
	$documentData = new DocumentData();
	$documentData->documentId = $document->id;
	$documentData->key = $key;
	$documentData->value = $value;
	$documentData->save();
}

 return View::make('documentA.edit', compact('project', 'document'));

So this all works fine, and when I create documentA using documentA's create view, I get an output like the database tables I have shown above.

I am then shown the edit page for that document. I think I have the form's model for this correct because it is now linked to a Project.

{!! Form::model($project->document, [
	'class'=>'form-horizontal',
	'method' => 'PATCH',
	'route' => ['projects.documents.update', $project->id, $document->id]
]) !!}

My issue is with the store function where I need to update this Document. Say for this Project I have created two documents; DocumentA and DocumentB. In the edit view for the document, if I do

{{ $document->documentData }}

I can see all the data related to that Document, no other document data is present (as it should be). However, in the update function, if I do

public function update(Request $request, Project $project, Document $document)
{
	dd($project->document);

	return null;
}

That shows me all documents, not just DocumentA as needed. As such, I think the model for the edit form is incorrect.

How can I get access to the correct Document within the update function?

Thanks
