@MRGUOKING plz fix the label inaccuracy:

[ffyuanda]

since we don't have priority (explicit) support in model yet, I will do this one first
casbin/casbin@49b7fe8#diff-a5ce247e55d5a20707517e34bef620f2eb369b4f9b8fa44fdfb2c18a702418e8

subjectPriority will come later

@sallycaoyu @Abingcbc we can work on this as next step

[Abingcbc]

@hsluoyz What should we do besides this subjectPriority https://github.com/casbin/pycasbin/blob/master/casbin/effect/__init__.py#L19 ?

[hsluoyz]

@techoner any advice for Abingcbc?

[sallycaoyu]

Seems like we need to implement the subjectPriority model for PyCasbin from scratch?
Link to an example of subjectPriority: https://casbin.org/docs/en/supported-models#examples

Is it a good approach if we start by looking at how it has been implemented in other Casbin repos?
https://github.com/casbin/casbin/search?q=subjectPriority&type=code

Please give us more advice on this, thank you!

@sallycaoyu Casbin-go implement this model. You can refer to that.
But casbin-go and casbin-python have different effector implementation. You may need additional work to implement it.

[sallycaoyu]

@Zxilly Thanks for the advice! I'll take a look at the effector first.

@sallycaoyu will be busy and cannot perform this task these days.

@Abingcbc can you take this issue as one of next steps?
