rbac组件之角色操作（二）

为了与stark组件分离，形成独立的模块，所以rbac数据表的操作需要单独进行操作，对角色表的操作。

urls.py

urlpatterns = [
    re_path(r'^roles/list/$', RoleView.as_view(),name='roles_list'),
    re_path(r'^roles/add/$', RoleAddView.as_view(), name='roles_add'),
    re_path(r'^roles/edit/(?P<rid>d+)/$', RoleEditView.as_view(), name='roles_edit'),
    re_path(r'^roles/dell/(?P<rid>d+)/$', RoleDelView.as_view(), name='roles_del'),
]
