Flask开发遇到的问题：BuildError: Could not build url for endpoint 'main.followers' with values ['username']. Did you mean 'main.user' instead?

描述

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

大意：端点main.followers与username无法建立链接

原因：未建立main.followers路由

解决方案

在main/view.py中新建视图函数，代码如下：

@main.route("/follow/<username>")
@login_required
@permission_required(Permission.FOLLOW)
def follow(username):
    user = User.query.filter_by(username=username).first()
