Iam遵循trydjango的django教程系列：为企业家编码，并且与django形式的“模型”和“字段”做了什么混淆 .
models.py
from django.db import models
# Create your models here.
class SignUp(models.Model):
email=models.EmailField()
full_name=models.CharField(max_length=55, blank=True, null=True)
timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
updated=models.DateTimeField(auto_now_add=False, auto_now=True)
def __unicode__(self):
return self.email
forms.py
from django import forms
from .models import SignUp
class SignUpForm(forms.ModelForm):
class Meta:
model=SignUp # ?
fields=['full_name','email'] # ?
def clean_email(self):
email=self.cleaned_data.get('email')
email_base,provider=email.split("@")
domain,extension=provider.split(".")
if not domain == 'USC':
raise forms.ValidationError("Please make sure you use your USC email")
if not extension == "edu":
raise forms.ValidationError("Please use valide edu address")
return email
def clean_full_name(self):
full_name = self.cleaned_data.get('full_name')
#write validation code
return full_name

您正在使用一个特殊的Form类，它允许您从指定的Model类自动地创建一个新的Form .
模型字段显示将从哪个模型创建表单，字段字段显示要在新表单中显示的Model类中的哪些字段 .
