动态FormRequest验证（Laravel）

Question

Is it possible to create a dynamic FormRequest validation in my function? See sample code below.

public function store(Request $request)
{
    Model::create($request->all());
    return redirect(url('/'));
}

What I mean is that I will change the "Request" parameter to the variable $formRequest.

My goal is that I would like to create different validation rules for a dynamic set of data of a single model.

If I could achieve this with other ways, please let me know. Thank you!

Edit:

Sample scenario: I have a form that has fields of First Name, Middle Name and Last Name.

First Rule:

public function rules()
{
    return [
    'firstname' => 'required',
    'middlename' => 'required',
    'lastname' => 'required'
    ];
}

Second Rule:

public function rules()
{
    return [
    'firstname' => 'required',
    'lastname' => 'required'
    ];
}

Where in the second rule only requires first and last name.

I just want to know if there are other ways of doing this rather than creating multiple store methods and adding more routes.

Skipping FormRequest and using the validate method on the $request instance can achieve this. Laracasts even has a lesson on it.

public function store(Request $request) {
    $rules = [/*...*/];

    $attributes = $request->validate($rules);

    Model::create($attributes);

    return redirect(url('/'));
}
