django 中model form的使用

django中可以把model转换成form

model form实际上就是继承model，它可以调用model的save方法以及定义字段， 其实model form 更多的是解决了重复性的问题

from django import forms
from operation.models import UserAsk 
import re

class UserAskForm(forms.ModelForm):
    class Meta:
        model = UserAsk
        fields = ['name', 'mobile', 'course_name']

    def clean_mobile(self):
        """
        验证手机号码是否正确
        """
        mobile = self.cleaned_data['mobile']
        REGEX_MOBILE = "^1[358]\d{9}$|^147\d{8}|^176\d{8}$"
        p = re.compile(REGEX_MOBILE)
        if p.match(mobile):
            return mobile
        else:
            raise forms.ValidationError(u"手机号码非法",code='mobile_invalid')

from django.http import HttpResponse

class AddUserAskView(View):
    """
    用户添加咨询
    """
    def post(self,request):
        userask_form = UserAskForm(request.POST)
        if userask_form.valid():
            user_ask = userask_form.save(commit=True)
            return HttpResponse("{'status':'success'}",content_type='application/json')
        else:
            return HttpResponse("{'status':'fail','msg':'添加出错'}",content_type='application/json')
