视图函数部分代码（如果删去 current_user.can(Permission.WRITE_ARTICLES) and 部分能运行）
@main.route('/', methods=['GET', 'POST'])
def index():
form = PostForm()
if current_user.can(Permission.WRITE_ARTICLES) and form.validate_on_submit():
post = Post(body=form.body.data,
author=current_user._get_current_object())
db.session.add(post)
db.session.commit()
return redirect(url_for('.index'))
page = request.args.get('page', 1, type=int)
model 部分代码：
class AnonymousUser(AnonymousUserMixin):
def can(self, permissions):
return False
def is_administrator(self):
return False
login_manager.anonymous_user = AnonymousUser
@main.route('/', methods=['GET', 'POST'])
def index():
form = PostForm()
if current_user.can(Permission.WRITE_ARTICLES) and form.validate_on_submit():
post = Post(body=form.body.data,
author=current_user._get_current_object())
db.session.add(post)
db.session.commit()
return redirect(url_for('.index'))
page = request.args.get('page', 1, type=int)
model 部分代码：
class AnonymousUser(AnonymousUserMixin):
def can(self, permissions):
return False
def is_administrator(self):
return False
login_manager.anonymous_user = AnonymousUser

我不懂 flask，但看你的报错我猜 current_user 是 AnonymousUserMixin 的实例，而不是 AnonymousUser，但是 current_user 在哪里声明的你又没有贴出来，迷真的很迷。。。。
