任何人都可以在以下示例中发现我做错了什么。当输入不正确的详细信息(例如无效的电子邮件地址)时,验证消息不会出现在我的模板中。模板正在加载,没有错误。
我排除了要在页面上打印的验证消息,但是由于某种原因,这突然停止工作。正如您从下面的代码示例中看到的那样,我将上下文中的表单传递回模板。这曾经有效,今天刚刚停止。
视图.py
if request.method == 'POST':
form = RegistrationForm(request.POST)
if form.is_valid():
# If form has passed all validation checks then continue to save member.
user = User.objects.create_user(
username=form.cleaned_data['username'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password']
)
user.save()
#member = User.get_profile()
#member.name = form.cleaned_data['name']
#member.save()
member = Member(
user=user,
name=form.cleaned_data['name']
)
member.save()
# Save is done redirect member to logged in page.
return HttpResponseRedirect('/profile')
else:
# If form is NOT valid then show the registration page again.
form = RegistrationForm()
context = {'form':form}
return render_to_response('pageRegistration.html', context,context_instance=RequestContext(request))
表格.py
