Question

我遇到了表单400错误，并尝试了其他解决方案。它让我的状态有所改善，但并没有阻止错误的发生。我有

模板/注册。html:

{% extends "base.html" %}

{% block title %}Register{% endblock %}

{% block content %}
    <h2> Welcome to the status page</h2>
    <br>
    <form action="/register" method="post" name="register_user">
        {{ form.hidden_tag() }}
        <h4>Register</h4>
        <p>
            Email:<br>
            {{ form.email }}<br>
            {% for error in form.email.errors %}
                <p><span style="color: red">[{{ error }}]</span></p>
            {% endfor %}
            Password:<br>
            {{ form.password }}<br>
            {% for error in form.password.errors %}
                <p><span style="color: red">[{{ error }}]</span></p>
            {% endfor %}
            Confirm password:<br>
            {{ form.confirm }}<br>
            {% for error in form.confirm.errors %}
                <p><span style="color: red">[{{ error }}]</span></p>
            {% endfor %}
        </p>
        <p><input type="submit" name="register" value="Submit"></p>
    </form>
    <p><a href="{{ url_for('login') }}">Log in</a></p>

<script type="text/javascript"> 

</script>

{% endblock %}

形式。py:

from flask.ext.wtf import Form
from wtforms import StringField, BooleanField, TextField, PasswordField, validators
from wtforms.validators import Required


class RegistrationForm(Form):
    # name = TextField('Your name', [validators.Length(min=2, max=60)])
    email = TextField('Email Address', [validators.Length(min=6, max=35)])
    password = PasswordField('New Password', [
        validators.Required(),
        validators.EqualTo('confirm', message='Passwords must match')
    ])
    confirm = PasswordField('Confirm Password')

这些观点。py:

    @application.route('/register', methods=['GET', 'POST'])
    def register():
        form = RegistrationForm(request.form)
        print(form)
        print(form.email.data)
        print(form.password.data)
        print(form.confirm.data)
        print(form.validate())
        if request.method == 'POST' and form.validate():
            user = User(email=form.email.data, password=form.password.data)
            user.save()
            flash('Thanks for registering')
            return redirect(url_for('awaiting_approval'))
        return render_template('register.html', form=form)

这些指纹看起来像

<app.forms.RegistrationForm object at 0x7ff762e11790>
[e-mail]
123456
1234
False

就像我预料的那样。我假设根据password字段的验证器重新呈现页面，并显示错误消息“Passwords must match”。我该怎么做才能让此表单失败并重新提交页面？非常感谢。

Answer 1

register.html：

<form action="{{url_for('register')}}" </form>

当您提交表单时，url_for将查看您的views.py寄存器功能。第二件事，您必须有一个名为的函数：awaiting_approval，因为您在发布成功后重定向此视图函数。
