werkzeug.routing.BuildError: Could not build url for endpoint 'main.edit_profile_admin' with values ['id']. Did you mean 'main.edit_profile' instead?
问题出现的环境背景及自己尝试过哪些方法
在user.html里面编辑adminstrator用户edit_profile的链接，模板中传入了参数id,视图函数里也有id参数，但报错信息好像说的是不能用值id作为端点构建url？网上搜索了类似的问题没有符合我的情况的
相关代码
app/main/view.py(部分）
@main.route('/edit-profile/<int:id>', methods = ['GET', 'POST'])
@login_required
@admin_required

python
修改
app/templates/user.html的部分内容如下：url_for('.edit_profile', id=user.id)应该的 endpoint 应该使用函数的名称。
