我有一些验证问题。当我提交表单时，form.is_valid(): 总是返回false。修改表单后，即从表单中删除所有验证后，它仍然返回false（我的表单未提交）
html的代码
{% 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>
<script>
$(function() {
$( "#id_birthday" ).datepicker();
});
</script>
{% endblock %}
{% block content %}
<form action="" method="post">
{% csrf_token %}
<div class="register_div">
<p><label for="username">Username:</label></p>
<p>{{ form.username }}</p>
</div>
<div class="register_div">
<p><label for="email">Email:</label></p>
<p>{{ form.email }}</p>
</div>
<div class="register_div">
<p><label for="password">Password:</label></p>
<p>{{ form.password }}</p>
</div>
<div class="register_div">
<p><label for="password1">Verify Password:</label></p>
<p>{{ form.password1 }}</p>
</div>
<div class="register_div">
<p><label for="birthday">Birthday:</label></p>
<p>{{ form.birthday }}</p>
</div>
<div class="register_div">
<p><label for="name">Name:</label></p>
<p>{{ form.username }}</p>
</div>
<p><input type="submit" value="submit" alt="register"/></p>
</form>
{% endblock %}
forms.py 的代码
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):

User.objects.get(username=username)

return password
class LoginForm(forms.Form):
username = forms.CharField(label=(u'User Name'))
password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))
和views.py的代码
def DrinkerRegistration(request):
if request.user.is_authenticated():
return HttpResponseRedirect('/profile/')
if request.method == 'POST':
form = RegistrationForm(request.POST)
#return render_to_response('register')
if form.is_valid():
user=User.objects.create_user(username=form.cleaned_data['username'], email=form.cleaned_data['email'], password = form.cleaned_data['password'])
user.save()
# drinker=user.get_profile()
# drinker.name=form.cleaned_data['name']
# drinker.birthday=form.cleaned_data['birthday']
# drinker.save()
drinker=Drinker(user=user,name=form.cleaned_data['name'],birthday=form.cleaned_data['birthday'])
drinker.save()
return HttpResponseRedirect('/profile/')
else:
return render_to_response('register.html',{'form':form} , context_instance=RequestContext(request))
else:
''' user is not submitting the form, show them a blank registration form '''
form = RegistrationForm()
context={'form':form}
return render_to_response('register.html',context , context_instance=RequestContext(request))
