django-guardian権限の管理に使用しています。デフォルトでは、各モデルにはadd、change、 の3 つのパーマがありdeleteます。たとえばview、独自のアクセス許可を追加すると、4 つすべてが [ユーザー管理] タブに表示され、4 つすべてが [モデル オブジェクト管理] タブに表示されます。

パーミッションをフィルタリングできることはわかっています: Django admin - パーミッション リストの変更

しかし、モデル オブジェクト管理タブでパーミッションをフィルターする方法がわかりません。それは可能ですか？

私はいくつかの仕事をしました。たぶんそれは最善の解決策ではありませんが、うまくいきます：

admin_utils.py:

class MyGuardedModelAdmin(GuardedModelAdmin):

    allowed_perms = []

    def get_perms_for_model(self, cls):
        if isinstance(cls, basestring):
            app_label, model_name = cls.split('.')
            model = models.get_model(app_label, model_name)
        else:
            model = cls
        ctype = ContentType.objects.get_for_model(model)
        return Permission.objects.filter(Q(content_type=ctype), Q(codename__in=self.allowed_perms) )

    def get_obj_perms_base_context(self, request, obj):
        context = {
            'adminform': {'model_admin': self},
            'media': self.media,
            'object': obj,
            'app_label': self.model._meta.app_label,
            'opts': self.model._meta,
            'original': hasattr(obj, '__unicode__') and obj.__unicode__() or\
                str(obj),
            'has_change_permission': self.has_change_permission(request, obj),
            'model_perms': self.get_perms_for_model(obj),
            'title': _("Object permissions"),
        }
        return context


    class MyAdminUserObjectPermissionsForm(AdminUserObjectPermissionsForm):

        def get_perms_for_model(self, cls):
            if isinstance(cls, basestring):
                app_label, model_name = cls.split('.')
                model = models.get_model(app_label, model_name)
            else:
                model = cls
            ctype = ContentType.objects.get_for_model(model)
            return Permission.objects.filter(Q(content_type=ctype), Q(codename__in=self.allowed_perms) )

        def get_obj_perms_field_choices(self):
            choices = [(p.codename, p.name) for p in self.get_perms_for_model(self.obj)]
            return choices

    def get_obj_perms_manage_user_form(self):
        setattr(self.MyAdminUserObjectPermissionsForm, 'allowed_perms', self.allowed_perms)
        return self.MyAdminUserObjectPermissionsForm


    class MyAdminGroupObjectPermissionsForm(GroupObjectPermissionsForm):
        def get_perms_for_model(self, cls):
            if isinstance(cls, basestring):
                app_label, model_name = cls.split('.')
                model = models.get_model(app_label, model_name)
            else:
                model = cls
            ctype = ContentType.objects.get_for_model(model)
            return Permission.objects.filter(Q(content_type=ctype), Q(codename__in=self.allowed_perms) )

        def get_obj_perms_field_choices(self):
            choices = [(p.codename, p.name) for p in self.get_perms_for_model(self.obj)]
            return choices

    def get_obj_perms_manage_group_form(self):
        setattr(self.MyAdminGroupObjectPermissionsForm, 'allowed_perms', self.allowed_perms)
        return self.MyAdminGroupObjectPermissionsForm

そして今、あなたはでフィルタリングすることができますallowed_perms

admin.py:

class PollAdmin(MyGuardedModelAdmin):
    allowed_perms = ['view_poll']

admin.site.register(Poll, PollAdmin)
