Laravel 7 resource model binding, no information in the edit page - laravel

Question

In Laravel 7 I did the following:
php artisan make:controller ClientGroupController --resource --model=ClientGroup
I modified the edit function in ClientGroupController to look as follows:
public function edit(ClientGroup $clientGroup)
{
return view('extranet.groups.create_modal_form', compact('clientGroup'));
}
I also added this route resource: Route::resource('groups', 'ClientGroupController');
A dd($clientGroup) in the view (when visiting the page http://127.0.0.1:8000/groups/2/edit) yields none of the data for the current record (a blank ClientGroup object).
Did I miss a step? Why does $clientGroup->id return null in my view (id is the primary key of the client_group table).

Answer 1

public function edit($id)
{
$clientGroup = ClientGroup::find($id);
return view('extranet.groups.create_modal_form', compact('clientGroup'));
}

Answer 2

I had a similar problem with resource routes defined like this:
Route::resource('others', OtherServiceController::class);
But my model name was OtherService
This was my edit and update function
public function edit(OtherService $otherService)
{
return view('others.master-edit', compact('otherService'));
}
public function update(OtherServiceRequest $request, OtherService $otherService)
{
$otherService->update($request->validated());
return redirect()->route('others.index')->withToastSuccess('Success Update Data');
}
But this code threw errors about a missing required parameter, because resource name and model name are not the same. So, my solution was to change the resource routes to match the model.
Route::resource('otherService', OtherServiceController::class);
Maybe you can read this question, marked answer tells about overriding
