我有一个关于flask_admin的错误,当我通过在我自己的类名UserDeleteView中从flask_admin.contrib.sqla继承ModelView类来创建自己的模型视图时,当我在UserDeleteView中使用current_user(flask_login的变量)时它给出None但是当我使用它在 UserDeleteView 的任何功能中都可以正常工作
就像我在 UserDeleteView 类的 is_accessable 函数中使用它一样,但是当我在 UserDeleteView 类的 if 中使用它时,它不起作用
这是我的 flask_admin 代码:-
class UserDeleteView(ModelView):
def is_accessible(self):
return "User" in {i.split()[0] for i in current_user.permissions() }
if "User w" not in current_user.permissions():
can_delete=False
class PostVarificationView(BaseView):
@expose("/")
def index(self):
return self.render('admin/post_varification.html')
class MyAdminIndexView(AdminIndexView):
def is_accessible(self):
return (current_user.is_authenticated and len(current_user.permissions())!=0)
admin = Admin(app,index_view=MyAdminIndexView(),name="Microblog")
admin.add_view(UserDeleteView( User, db.session ))
admin.add_view(PostVarificationView(name="Post Varification",endpoint="PostVarification"))
这是我得到的错误:
AttributeError: 'NoneType' object has no attribute 'permissions'
