Question

这篇文章扩展了error while submitting data in the form django

model.py

from django.db import models

# Create your models here.

class Profile(models.Model):
     name = models.CharField(max_length=50, primary_key=True)
     assign = models.CharField(max_length=50)
     doj = models.DateField()

     class Meta:
        db_table= 'profile'


     def __unicode__(self):

       return  u'%s' % (self.name)



class working(models.Model):
   w_name =models.ForeignKey(Profile, db_column='w_name')
   monday =  models.IntegerField(null=True, db_column='monday', blank=True)
   tuesday =  models.IntegerField(null=True, db_column='tuesday', blank=True)
   wednesday =  models.IntegerField(null=True, db_column='wednesday', blank=True)

   class Meta:
        db_table = 'working'



   def __unicode__(self):
      return  u'%s ' % ( self.w_name)


view.py

# Create your views here.
from forms import *
from django import http
from django.shortcuts import render_to_response, get_object_or_404


def index(request):
   obj=working()
   obj.w_name='X'
   obj.Monday=1
   obj.Tuesday=2
   obj.Wednesday =3
   obj.save()
   return http.HttpResponse('Added')

如果有人点击http://127.0.0.1:8000/

，我想直接在表格中插入数据

但它会抛出任何想法错误？

异常类型：ValueError at / 例外值：无法分配“u'x'”：“working.w_name”必须是“个人资料”实例。

Answer 1

我以为你说你想把价值注入表格？

在这种情况下，很明显（看它比评论更好），你需要将Profile实例传递给你的工作对象，就像我们在你的另一篇文章中使用表单清理方法一样。

def index(request):
   try: 
       profile = Profile.objects.get(pk='X')
   except Profile.DoesNotExist:
       assert False # or whatever you wish
   obj=working()
   obj.w_name= profile
   obj.Monday=1
   obj.Tuesday=2
   obj.Wednesday =3
   obj.save()
   return http.HttpResponse('Added')

提交表单时的外键问题
