Question

I'm pretty sure my problem is somewhere in this part of my code.我很确定我的问题出在我的这部分代码中。 If I change <form action="/update/{id}"to login, I can get all the routes running the way they should and allowing the user to enter a new password and send them to the login screen.如果我将 <form action="/update/{id}" 更改为登录，我可以让所有路由按应有的方式运行，并允许用户输入新密码并将它们发送到登录屏幕。 But I can not figure out how to get it to save that password and then let the user login with the new password.但我不知道如何让它保存该密码，然后让用户使用新密码登录。

@app.route('/update/<int:id>', methods=['GET', 'POST'])
@login_required
def update(id):
form = UpdatePasswordForm()
userPass = User.query.get(id)
if request.method == "POST":
    userPass.password = request.form['password']


    try:
        db.session.commit()
        flash("User Updated Successfully!")
        return render_template("update.html",
                               form=form,
                               userPass=userPass,
                               id=id)
        redirect(url_for('login'))

    except:
        flash("Error! There was a problem changing your password")
        return render_template("update.html",
                               form=form,
                               userPass=userPass,
                               id=id)
        redirect(url_for('update'))
else:
    return render_template("update.html",
                           form=form,
                           userPass=userPass,
                           id=id)
    redirect(url_for('update'))

I guess you are missing some brackets here in the id variable我猜您在 id 变量中缺少一些括号

<form action="/update/{id}" method="POST">

It should be instead应该改为

<form action="/update/{{id}}" method="POST">

Jinja needs double curly braces for variables. Jinja 需要双花括号来表示变量。 https://jinja.palletsprojects.com/en/3.0.x/templates/#variables https://jinja.palletsprojects.com/en/3.0.x/templates/#variables
