Question

我发出请求时，我的django.test客户端返回的响应状态码为200，而不是重定向为状态码302。

我正在将Django 2.2.4与Python 3.7.3结合使用。

不需要登录（由Why does Django Redirect Test Fail?处理），也没有将follow和secure参数设置为True（由Django test client POST command not registering through 301 redirect处理）

我注意到相同的问题会影响我的更新视图。当我使用put方法调用Django Test Client时，它不会重定向。（我没有包含此代码以避免冗长）。

最后，我注意到当我python manage.py runserver然后访问页面以创建新的Book实例时，页面重定向有效。

这是测试：

from django.test import TestCase, Client
from django.urls import reverse
...

class TestDashboardViews(TestCase):
    def setUp(self):
        self.client = Client()
        self.book_list_url = reverse("dashboard-home")
        self.book_create_url = reverse("dashboard-upload-book")
        self.another_demo_book_kwargs = {
            "title": "Demo Title",
            "author": "Demo Author",
            "subject": "Another Demo Subject",
            "details": "Another Demo Details",
            "file": "path/to/another/demo/file"
        }
        ...

    def test_book_create_view_using_post_method(self):
        response = self.client.post(self.book_create_url, self.another_demo_book_kwargs)

        self.assertRedirects(response, self.book_list_url)
        ...

这是受影响的视图：

class BookCreateView(CreateView):
    model = Book
    fields = ['title', 'author', 'subject', 'details', 'file']
    success_url = reverse_lazy("dashboard-home")

这是模型：

from django.db import models
from django.utils.text import slugify


class Book(models.Model):
    title = models.CharField(max_length=50)
    slug = models.SlugField()
    author = models.CharField(max_length=100)
    subject = models.CharField(max_length=50)
    details = models.CharField(max_length=255)

    def author_title_path(self, filename):
        return "files/{author}/{filename}".format(author=slugify(self.author), filename=filename)

    file = models.FileField(upload_to=author_title_path)

    def save(self, *args, **kwargs):
        title_by_author = "{title} by {author}".format(title=self.title, author=self.author)
        self.slug = slugify(title_by_author)
        super().save(*args, **kwargs)

这是我的网址：

from django.urls import path
from dashboard.views import BookListView, BookCreateView, BookUpdateView, BookDeleteView

urlpatterns = [
    path("", BookListView.as_view(), name="dashboard-home"),
    path("add_book/", BookCreateView.as_view(), name="dashboard-upload-book"),
    path("edit_book/<slug>/", BookUpdateView.as_view(), name="dashboard-edit-book"),
    path("delete_book/<slug>/", BookDeleteView.as_view(), name="dashboard-delete-book")
]

我的测试失败，并显示以下错误：

...
AssertionError: 200 != 302 : Response didn't redirect as expected: Response code was 200 (expected 302)
...

请帮助。

丹尼尔·罗斯曼（Daniel Roseman）和Dirkgroten帮助在评论中找出问题所在。

我建议检查出问题dirkgroten所指的是（how to unit test file upload in django）

问题出在测试设置中创建的self.another_demo_book_kwargs中的文件字段中。

文件字段需要一个实际文件，而不仅仅是路径。

此：

self.another_demo_book_kwargs = {
            "title": "Demo Title",
            "author": "Demo Author",
            "subject": "Another Demo Subject",
            "details": "Another Demo Details",
            "file": "path/to/another/demo/file"
        }

应替换为：

with open(ABSOLUTE_FILE_PATH) as file_object:
            data = {
                "title": "Demo Title",
                "author": "Demo Author",
                "subject": "Another Demo Subject",
                "details": "Another Demo Details",
                "file": file_object
            }
            response = self.client.post(self.book_create_url, data)

Django测试客户端发布请求无法重定向
