在测试期间,如何将django视图GET请求的响应插入到与POST请求相同的视图中?
我有一个基于Django函数的表单视图,它在GET请求中使用默认数据初始化表单,并在POST请求中保存模型对象:在测试期间,如何将django视图GET请求的响应插入到与POST请求相同的视图中?,django,python-3.x,django-forms,django-testing,Django,Python 3.x,Django Forms,Django Testing,我有一个基于Django函数的表单视图,它在GET请求中使用默认数据初始化表单,并在POST请求中保存模型对象: def copy(request, ann_id): new_ann = get_object_or_404(Announcement, pk=ann_id) new_ann.pk = None # autogen a new primary key (quest_id by default) new_ann.title = "Copy of " + new
def copy(request, ann_id):
new_ann = get_object_or_404(Announcement, pk=ann_id)
new_ann.pk = None # autogen a new primary key (quest_id by default)
new_ann.title = "Copy of " + new_ann.title
new_ann.draft = True
new_ann.datetime_released = new_ann.datetime_released + timedelta(days=7)
form = AnnouncementForm(request.POST or None, instance=new_ann)
if form.is_valid():
new_announcement = form.save(commit=False)
new_announcement.author = request.user
new_announcement.datetime_created = timezone.now()
new_announcement.save()
form.save()
return redirect(new_announcement)
context = {
"title": "",
"heading": "Copy an Announcement",
"form": form,
"submit_btn_value": "Create",
}
return render(request, "announcements/form.html", context)
如果不在我的视图中手动将表单数据提供给self.client.post(url,form\u data)
,我就不知道如何在发布表单时测试form.is\u valid()
分支
以下是我正在尝试的:
测试视图.py
class AnnouncementViewTests(TestCase):
def setUp(self):
self.client = ...
... etc
def test_copy_announcement(self):
# log in a teacher
success = self.client.login(username=self.test_teacher.username, password=self.test_password)
self.assertTrue(success)
# hit the view as a get request first, to load a copy of the announcement in the form
response = self.client.get(
reverse('announcements:copy', args=[self.test_announcement.id]),
)
self.assertEqual(response.status_code, 200)
# The form in this response should be valid, and should bw
# accepted on a post request,
# that is what I am testing in this integration test.
form_data = response.how_do_get_the_form_data() # ???????
response = self.client.post(
reverse('announcements:copy', args=[self.test_announcement.id]),
data=form_data
)
# Get the newest announcement just made in the post request
new_ann = Announcement.objects.latest('datetime_created')
self.assertRedirects(
response,
new_ann.get_absolute_url()
)
我想要实际测试的是get
的结果为表单提供了有效的默认数据,然后可以通过post
请求提交这些数据
但是我不知道如何访问get
请求产生的表单数据,因此我可以将其输入到提供给post
请求的表单数据中
编辑
我在get响应中找到了表单的位置,但我不知道如何在代码中找到它
你的问题有点让人困惑,但我会尽力引导你正确的方向 要清理代码,应使用基于类的视图,您可以在任何地方轻松使用表单。我刚刚编写的示例代码:
class TestView(View):
template_name = 'index.html'
success_url = 'home' # dummy view
context = {"form": myform()}
# myform is the definition/class of your form which contains all attrs.
def get(self, request):
context = self.context
context['form'] = form # fill out your data here for get request
return render(request, self.template_name, context)
def post(self, request):
context=self.context
# self.context certain that you're using exact form which you defined in class-scope
form=context['form']
# Form Validation
if form.is_valid():
#perform any logical validations here and save the form if required
return redirect(self.success_url)
context = self.context
context['form'] = form # just to show you that you can access that form anywhere
return render(request, self.template_name, context)

您可以像这样手动将数据传递给表单,并在单元测试中测试
是否有效
函数:
form_data = {'my': 'value', 'form': 'value', 'fields': 'value'}
form = AnnouncementForm(form_data)
self.assertFalse(form.is_valid)

您可以通过以下方式访问响应表单:
response.context['form']
从这里,您可以通过以下方式构建有效负载:
retrieved_instance=response.context['form'].instance
表单_data=dict(title=retrieved _instance.title,…)以了解主要概念。您可以通过以下方式访问响应表单:

字段值复制到dict中,而不手动列出所有字段?您可以使用response.context['form'].initial
,即dict,而不是response.context['form'].instance
这太接近了!initial
几乎可以直接插入,除了它包含post请求抱怨的一些值,如None
