flask开发中遇到werkzeug.routing.BuildError:Could not build u

flask开发中遇到werkzeug.routing.BuildError:?Could not build url for endpoint 'main.user' with values ['username']. Did you mean 'auth.user' instead?

错误意思是：无法和端点'main.user'与username的值建立联系，你是不是应该用‘auth.user’代替？

这一步是出现在，注册用户成功，页面跳转和未激活用户登陆账号成功后页面跳转出现的。

代码：templated/base.html

出错的代码是：

<a?href="{{?url_for('main.user',?username=current_user.username)}}">

url_for('main.user')

而实际上main/views.py中并且没有这个视图，而我在auth/views.py 有这个视图。

正确方式是：在main.views.py增加以下代码：

@main.route('/user/<username>')
def?user(username):
????user?=?User.query.filter_by(username=username).first_or_404()
????return?render_template('user.html',?user=user)
