联合唯一

clean_字段方法只能对某个字段进行检查，当clean方法执行完之后，最后还会执行clean方法，在clean方法中，可以通过获取数据字典中的值然后进行验证

　　

from django.shortcuts import render,HttpResponse

from django import forms

from django.forms import fields


# Create your views here.
#联合唯一

class Form1(forms.Form):
    username=fields.CharField(
        max_length=32

    )
    email =fields.CharField(
        max_length=32)
    def clean_username(self):
        print('this is clean_')
        return self.cleaned_data['username']
    def clean(self):
        value_dict=self.cleaned_data
        username=value_dict.get('username')
        email=value_dict.get('email')
        if username=='ye' and email=='hai':
            print('this is clean')
            return value_dict
def index(request):
    if request.method=='GET':
        obj=Form1()
        return render(request,'index.html',{'obj':obj})
    if request.method=='POST':
        obj=Form1(request.POST)
        if obj.is_valid():
            print('hahah')
            return HttpResponse('提交成功')
        else:
            return render(request,'index.html',{'obj':obj})
