Allow write-action also to read (level based permissions)

[AxelRHD]

Want to prioritize this issue? Try:

---

I would like to create a model, where the actions are based on levels. So a higher level inherits all the actions from the lower ones. E. g. if a subject has write-permission, it also has read-permission without defining it explicitly. Is that possible with casbin?

Or what is the best solution?

Thanks.
