Symfony2 — render or redirect?

Question

What is better? Returned redirect or to make render after successful submit form?

Redirect:

public function newAction(Request $request)
{
    // ...

    if ($form->isValid()) {

        return $this->redirect(/* ... */);
    }

    return $this->render(/* ... */);
}

Second:

public function newAction(Request $request)
{
    // ...

    if ($form->isValid()) {

        return $this->render(/* ... */);
    }

    return $this->render(/* ... */);
}

`redirect()` so you can't resubmit the form by refreshing the page. — D4V1D, Nov 26 '15 at 08:11

If a form was sent via POST method - the best way is to redirect a user to the some page (for example, to the list of entities). It prevents resubmitting form by a user again.

Better use redirectToRoute() method for Symfony >=2.6

But if you work with GET method - you definitely want to use render() method (for example, in order to display some filtering entities or data based on your GET-query).
