我有一个非常简单的观点:
from models import Item, Tag, Category, User
from django.views.decorators.csrf import csrf_exempt
from django.http import HttpResponse
def save_item(request):
try:
print request.GET
i = Item()
i.user = User.objects.get_or_create(email=request.GET['user_email'][0])
i.save()
print i
except Exception as e:
print e.message()
return HttpResponse()
使用这些非常简单的模型:
class User(models.Model):
email = models.EmailField()
class Item(models.Model):
category = models.ForeignKey(Category, null=True, blank=True)
tags = models.ManyToManyField(Tag, null=True, blank=True)
address = models.CharField(max_length = 512, null=True, blank=True)
user = models.ForeignKey(User)
data = models.CharField(max_length = 1024, null=True, blank=True)
打印是我的 error.log 中唯一显示的内容:
[Wed May 16 01:23:40 2012] [error] <QueryDict: {u'website': [u''], u'comment': [u''], u'rating': [u''], u'phone number': [u''], u'address': [u''], u'user_email': [u'cc.emeraldeyes@gmail.com']}>
但是没有创建 Item 模型实例!
我可以在管理员或 shell 中手动创建一个:

>>> from RemoteStorage.models import Item
>>> i = Item()
>>> from RemoteStorage.models import User
>>> i.user = User.objects.get(pk=1)
>>> i.save()
# THIS WORKS
但是试图在 View 中保存一个只是……失败了。默默。为什么？？!!!
请您参考如下方法:
get_or_create返回元组
user, created = User.objects.get_or_create(email=request.GET['user_email'][0])
