Use code tags.Also put the real code you are using. Your code cannot even run let alone get 400 response
Aver eso es un ejemplo de los metodos que intento hacer que funcionen. La cuestión es que el redirect no me funciona es que hay q configurar algo mas en yii o algo?
Tienes que poner un ejemplo real para que uno se dé cuenta. Además, no muchos, incluido yo, saben español. Es el traductor de Google el que acaba de rescatar la situación 
To be very general, check parameters defined in the action you are redirecting to’
class TestsController
{
public function actionProfile($user){
//some stuff here
}
//Let us redirect wrong way
public function actionWrongRedirect(){
$someId = ....//get the id
return $this->redirect(['profile', 'id' => $someId]); //BAD request, user is missing
}
//Let us redirect correct way
public function actionCorrectRedirect(){
$someId = ....//get the id
return $this->redirect(['profile', 'user' => $someId]);
}
}
This should work. Can you copy and paste (not screenshot) the whole Stack trace?
The 400 (Bad Request) status code indicates that the server cannot or will not process the request because the received syntax is invalid, nonsensical, or exceeds some limitation on what the server is willing to process. It means that the request itself has somehow incorrect or corrupted and the server couldn’t understand it. The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method . Therefore, it prevents the website from being properly displayed. The main thing to understand is that the 400 Bad Request error is a client-side error.
The cause of a 400 error can be a wrongly written URL or a URL that contains unrecognizable characters. Another cause of the error might be an invalid or expired cookie. Also, if you try to upload a file that’s too large. If the server is programmed with a file size limit, then you might encounter a 400 error.
