如何在Django的CreateView中测试get_success_url

from django.test import TestCase
from django.urls import reverse
from django.contrib.auth.models import User
from django.views.generic import CreateView

from myapp.models import MyModel

class CreateViewTest(TestCase):
    def setUp(self):
        self.user = User.objects.create_user(username='testuser', password='testpassword')
        self.client.login(username='testuser', password='testpassword')
        self.url = reverse('create_view_url')
        self.data = {
            'field1': 'value1',
            'field2': 'value2',
            # 添加其他字段的值
        }

    def test_get_success_url(self):
        response = self.client.post(self.url, data=self.data)
        self.assertEqual(response.status_code, 302)  # 检查是否重定向到成功页面
        self.assertEqual(response.url, reverse('success_url'))  # 检查重定向的URL是否正确

    def test_create_object(self):
        response = self.client.post(self.url, data=self.data)
        self.assertEqual(response.status_code, 302)  # 检查是否重定向到成功页面
        self.assertEqual(MyModel.objects.count(), 1)  # 检查是否成功创建了对象
        obj = MyModel.objects.first()
        self.assertEqual(obj.field1, 'value1')  # 检查字段值是否正确
        self.assertEqual(obj.field2, 'value2')
        # 检查其他字段的值

    def test_authenticated_user_required(self):
        self.client.logout()
        response = self.client.post(self.url, data=self.data)
        self.assertEqual(response.status_code, 302)  # 检查是否重定向到登录页面

    def test_template_used(self):
        response = self.client.get(self.url)
        self.assertTemplateUsed(response, 'create_view_template.html')  # 检查是否使用了正确的模板

    def test_form_valid(self):
        response = self.client.post(self.url, data=self.data)
        self.assertEqual(response.status_code, 302)  # 检查是否重定向到成功页面
        # 可以根据具体的业务逻辑编写其他的form_valid测试
