has_role_decorator catch exception

[MiltosD]

I am trying to use this package with rest framework. However, the "has_role_decorator" function raises an exception when the user does not have the role, as expected. Is it possible to catch this exception in my ViewSet in order to return a "Permission Denied" REST response?

I suppose overriding HasRoleMixin.dispatch could work, however, I cannot seem to handle read_only if has_role_decorator fails

Hi @MiltosD, what do you mean by read_only? Could you check for the request method before suppressing the exception or not?
