Yii2 how to write such rule for Urlmanager?

Question

Yii

Hello, there is a rule:

'repetitory/<city>' => 'search-tutor/index',
'repetitory/<subject>' => 'search-tutor/index',

The parameter can be a city or an object, but in the end, in any case, only the first rule works.
In all cases, $_GET['city'] returns the value of city and subject, while $_GET['subject'] returns nothing.

Answer 1

What about the meaning?
Naturally, everything will go in one, understand inside the controller what to look for there. determine on the go what has come.
How should it parse itself what kind of link it is?
After all, it even goes to one controller and method, what is the point of this action then?

Answer 2

'repetitory/<city>/<subject>' => 'search-tutor/index',
'repetitory/<city>' => 'search-tutor/city',

It's best to do so. Since your subject can theoretically be the same in several cities, and then it will generally be unclear from which city to pull the subject.
