django crm 左側二級菜單欄

1.如何生成二級菜單欄html

　　在 rbca表中生成一張表 menu ，表示可能須要給客戶展現的一級菜單欄django

　　在permission表中，建立字段，經過多對一外鍵關係，關聯到menu表，表示哪些permission要在二級菜單欄顯示，顯示到哪一個一級菜單欄下面session

　　在initial_session 權限注入的時候，注入一個字典 permission_menu_dict > 格式以下：數據結構

'''目標數據結構
 { 1:{  # 1--menu_id 'title':'..', 'icon':'xx', children:[ {'title':'二級','url':'xx'}, {'title':'二級','url':'xx'}, ] }, 2:{  # 2--menu_id 'title':'..', 'icon':'xx', children:[ {'title':'二級','url':'xx'}, {'title':'二級','url':'xx'}, ] } } '''

rbac.py

　　在自定義標籤中循環該字典生成標籤app
