If set, the Meta attribute "rules_permissions" has to be a dictionary with permission types (like "add" or "change") as keys and predicates (like rules.is_staff) as values. Permissions are then registered with the rules framework automatically upon Model creation. This mixin can be used for creating custom metaclasses. c |jd}t|drJ|j}|`t|tst d|dt |d|j}ni}t |$||||fi|}||j_|j||jD] \}} t|j|| "|S)NMetarules_permissionsz%The rules_permissions Meta option of z must be a dict, not .)gethasattrr isinstancedictrtypecopysuper__new___metapreprocess_rules_permissionsitemsrget_perm) clsnamebasesattrskwargs model_metaperms new_class perm_type predicate __class__s >/root/env/lib/python3.12/site-packages/rules/contrib/models.pyrzRulesModelBaseMixin.__new__sYYv& :2 300E,eT**T%[*JJLEEGOCueFvF ,1 )..u5$)KKM ?
