I’m currently building a gaming app where a currently logged in user has access to play different games based on their rank in our application.
So if a currently logged in user has a rank of let’s say 100 than all the games with a game rank of 100 and below will be displayed. The rest of the games will be locked.
I can’t get this currently fully to work with my code.
What do I need to change with my code?
If I test using When(game_rank__lte=25, then=Value(True)),
that seems to work, I can see both locked and unlocked games based on the value of 25 and less.
But when I do When(game_rank__lte=user_profile_rank, then=Value(True)),
that doesn’t seem to work. All the games are unlocked and none are locked.
The rank of each game is the game_rank
field in the Game_Info
model.
The rank of the currently logged in user is the rank
field in the User_Info
model.
Any help is gladly appreciated.
Thanks!
