请使用Django测试客户端帖子请求帮助测试有效的表单帖子？
response = self.client.post('/accounts/create_thing/', { 'name': dummy_thing.name, 'description': dummy_thing.description, })
这是TestCase代码段：
from django.test import TestCase, RequestFactory

from collection.models import Thing
from .views import *
from collection.forms import ThingForm
class SampleTest(TestCase):

# Every test needs access to the request factory.
self.factory = RequestFactory()
self.dummy_user = User.objects.create_user(username='dummy', password='nothings')
self.dummy_thing = Thing.objects.create(name="Dummy Book",
description="Book For Dummies.",
slug="dummy-book",
user=self.dummy_user)
def test_form(self):
dummy_thing = Thing.objects.get(name="Dummy Book")
form = ThingForm(instance=dummy_thing)
self.assertFalse(form.is_valid()) # No data has been supplied yet.
form = ThingForm({ 'name': dummy_thing.name, 'description': dummy_thing.description, }, instance=dummy_thing)
self.assertTrue(form.is_valid())
def test_form_post(self):
dummy_thing = Thing.objects.get(name="Dummy Book")

# Test POST invalid data

# Test POST valid data?
# response = self.client.post('/accounts/create_thing/', { 'name': dummy_thing.name, 'description': dummy_thing.description, })

注意：user = models.OneToOneField（User，blank = True，null = True）
＆＃34; Thing.user＆＃34;必须是＆＃34;用户＆＃34;实例
列user_id必须是唯一的。

由于
答案 0 :(得分：2)
这是因为您有OneToOneField，因为您的每个新Thing都必须连接到之前未被选中的User。因为您已将dummy_thing dummy_user作为User，因此您无法使用相同的Thing保存新的dummy_user个实例。
我认为您的意图是每个Thing都有一个User，因此您应该使用ForeignKey代替OneToOneField。
但如果我错了，如果你真的需要OneToOneField，那么为了测试你的POST请求只需创建新用户并以新用户身份登录，那么thing.user = request.user将会dummy_user2 1}}并且不会与唯一值冲突。
