问题 In my App I store data in Realm database and display data in UITableView. I add cool feature at table - now I can swap cells by drag and drop. But now I have to add method to DataBase class to swap related objects. I've figured out that Realm is unordered, so I thought about adding one more property: index. But consequently I should raise all logic about indexing items in datamodel(insert at index, remove at index, etc), it seems to me wrong approach. Interesting is there common way to solve

问题 Can not log out from keycloak IDP from inside of Django app code. All stackoverflow answers did not work fo me (most are for older version of the components involved), the same goes for the keycloak documentation.
