decorator predicates

[jbaumgarten]

Hi guys,

I was using some checks to limite the access on some commands. Generally the has_any_role check was enough but I need a version which allows me to pass a dictionary to it to split role from guild (easier to read and check)

I tried several things but I don't succeed to call the has_any_role method in my own made check.
How can I proceed?

Yours sincerely,
Julien

What does this dict look like? Considering that has_any_role takes role names or IDs, I can't think of a dictionary format that it could accept...

As for a custom implementation, you can simply call and return the check, like the following:

def custom_has_any_role(*roles: dict[Any, Any] | int | str):
    return commands.has_any_role(*<your values>)
    

# @custom_has_any_role(...)

Also, consider joining the support server and asking for help there—it's easier IMO.

To call the predicate from your custom check, it would be as follows: await commands.has_any_role(*values).predicate(ctx) which would either return True or raise the appropriate error.

However (in my opinion), what you're doing seems rather peculiar and it seems like it is somewhat stepping away from the intended scope of decorator checks. If you're doing something that would account for many guilds and roles, a different approach with your custom check, relying in something more robust like a database instead of manually typing it out could be better, and also easier to modify (via a command that could whitelist a role or user perhaps?).

Thx @Soheab @LeoCx1000
I gave an example to understand how to use another predicate in my custom predicate but yeah the example goal was strange :D

However, is it possible to get access to the bot client (and attributs) in a predicate as only the ctx was passed as argument

[LeoCx1000]

You can access ctx.bot, as stated in the documentation
