Django的形式是有效的()失败 [英] django form is valid() fails
问题描述
我正在尝试使用django创建注册表单,当我提交表单时,valid()函数会失败,并且我不确定为什么.我将我的注册和登录页面全部放在一个html页面上,尽管我将所有字段名称都称为不同的名称,例如login_username.
I am trying to create a registration form using django, when I submit my form the is valid() function fails and I am not sure why. I have my registration and login page all on one html page, although, I have called all the field names different names, eg login_username.
forms.py
class SignUpForm(forms.Form):
username = forms.CharField(label='Username', max_length=20,widget=forms.TextInput(attrs={'class': 'form-control','placeholder':'Enter Username'}))
conUsername = forms.CharField(label='Confirm Username', max_length=20,widget=forms.TextInput(attrs={'class': 'form-control','placeholder':'Confirm Username'}))
firstName = forms.CharField(label='First Name', max_length=20,widget=forms.TextInput(attrs={'class': 'form-control','placeholder':'Enter Firstname'}))
lastName = forms.CharField(label='Last Name', max_length=20,widget=forms.TextInput(attrs={'class': 'form-control','placeholder':'Enter LastName'}))
email = forms.CharField(label='Email', max_length=220,widget=forms.TextInput(attrs={'class': 'form-control','placeholder':'Enter Email','type':'email'}))
conEmail = forms.CharField(label='Confirm Email', max_length=220,widget=forms.TextInput(attrs={'class': 'form-control','placeholder':'Confirm Email','type':'email'}))
password = forms.CharField(label="Confirm Password", max_length=20,widget=forms.TextInput(attrs={'class': 'form-control','type':'password','placeholder':'Enter Password'}))
conPassword = forms.CharField(label="Confirm Password", max_length=20,widget=forms.TextInput(attrs={'class': 'form-control','type':'password','placeholder':'Confirm Password'}))

推荐答案
现在您的表单始终为空,因此无效.您忘记了将请求POST内容添加到表单中.
Right now your form is always empty and therefore invalid. You forgot to add the request POST content to the form.
def SignUp(request):
# ...
if request.method == 'POST':
regForm = SignupForm(request.POST) # form needs content
if regForm.is_valid():
# ...
如果在调用 .is_valid()
时卡住,则可以 print(regForm.errors)
查看最新消息.
If you get stuck when calling .is_valid()
, you can print(regForm.errors)
to see what's up.
