当我提交表单时，我在forms.py第25行password1=self.cleaned_data['password1']中的password1处得到KeyError。文件代码如下：
forms.py的代码是：
from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
from drinker.models import Drinker
class RegistrationForm(ModelForm):
username = forms.CharField(label=(u'User Name'))
email = forms.EmailField(label=(u'Email Address'))
password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))
password1 = forms.CharField(label=(u'Verify Password'), widget=forms.PasswordInput(render_value=False))
class Meta:
model=Drinker
exclude=('user',)
def clean_username(self):
username=self.cleaned_data['username']
try:
User.objects.get(username=username)
except User.DoesNotExist:
return username
raise forms.ValidationError("The Username is already taken, please try another.")
def clean_password(self):
password=self.cleaned_data['password']
password1=self.cleaned_data['password1']
if password != password1:
raise forms.ValidationError("The Password did not match, please try again.")
return password
html文件的代码是：
{% extends "base.html" %}
{% block extrahead %}
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js" type="text/javascript"></script>

$(function() {
$( "#id_birthday" ).datepicker();
});
</script>
{% endblock %}
{% block content %}
<form action="" method="post">

<p><label for="birthday"{% if form.birthday.errors %} class="error"{% endif %}>Birthday:</label></p>
<p>{{ form.birthday }}</p>

<div class="register_div">

<p><label for="name"{% if form.name.errors %} class="error"{% endif %}>Name:</label></p>

最佳答案
Django为表单中的每个字段调用clean_xxx()方法。当一个字段有效时，它将把键/值添加到cleaned_data。当Django调用clean_password并且它还没有处理字段password1时，cleaned_data将不包含password1的键/值对。这就是您当前遇到的错误。
要解决这个问题，您需要将密码验证移到clean()中，这是在Django分别检查每个字段之后调用的。此方法可用于执行涉及表单的多个字段（即整个表单）的验证。
这也很有意义，因为您要引发的错误是关于password和password1之间的不匹配，而不仅仅是字段password（您当前正在清理的字段）。
