python - 类型错误 : 'bool' object is not callable g. user.is_authenticated()

Question

<分区>

Answer 1

尝试将 if g.user.is_authenticated(): 替换为 if g.user.is_authenticated:，如下所示:

@app.before_request
def before_request():
    g.user = current_user
    if g.user.is_authenticated:
       g.search_form = None

来自 the document :

is_authenticated

Returns True if the user is authenticated, i.e. they have provided valid credentials. (Only authenticated users will fulfill the criteria of login_required.)

如文档所述，is_authenticated 是一个 bool 值(True 或 False)。

然而，它在过去是一个函数，but it has been changed to boolean at version 3.0 :

BREAKING:
The is_authenticated, is_active, and is_anonymous
members of the user class are now properties, not methods. Applications should update their user classes accordingly.
