Question

我一直试图在Django中测试一个表单ChoiceField。

我有Form个ChoiceField：

class PickPlanForm(forms.Form):
    "Set the `plan` session cookie for choice here."

    plan_choices = Plan.objects.get_choices()

    # Field
    plan = forms.ChoiceField(required=True, choices=plan_choices)

这是我的plan_choices：

的元组列表

[('Bronze', 'Bronze ($10.00 per month)'),
 ('Silver', 'Silver ($20.00 per month)')]

我试图通过以下方式测试它：

response = self.client.post(reverse('payment:register_step3'),
    {'plan': 'Bronze'}, follow=True)
self.assertRedirects(response, reverse('payment:register_step4'))

但是，在运行我的测试时，我不断收到错误回溯：

Traceback (most recent call last):
  File "/Users/aaron/Documents/djcode/textress_concierge/textress/main/tests/test_views.py", line 170, in test_register_step3
    self.assertRedirects(response, reverse('payment:register_step4'))
  File "/Users/aaron/Documents/virtualenvs/textress/lib/python3.4/site-packages/django/test/testcases.py", line 263, in assertRedirects
    (response.status_code, status_code))
AssertionError: False is not True : Response didn't redirect as expected: Response code was 200 (expected 302)

我正在使用：

Django 1.6.8
Python 3.4

我认为这很容易让我失踪？

谢谢

修改：添加视图

from django.views.generic import FormView
from braces.views import LoginRequiredMixin

class PickPlanView(LoginRequiredMixin, FormView):
    """
    Step #3 of Registration

    Pick a Plan, and save the Plan as a `session cookie` before creating
    the Stipe Customer/Subscription using the Plan Choice.
    """
    template_name = 'main/hotel_form.html'
    form_class = PickPlanForm
    success_url = reverse_lazy('payment:register_step4')
    authenticated_redirect_url = settings.VERIFY_LOGOUT_URL

    def get_form_kwargs(self):
        """Add the `request` Obj to Form, so I can set the PlanPick as a
            session cookie for the time being."""
        kwargs = super().get_form_kwargs()
        kwargs['request'] = self.request
        return kwargs

观点说明：

它只接受表格选择。

我手动测试它时有效。

我只是遇到了Django ChoiceField Test部分的问题，因为我之前没有对ChoiceField进行过测试。

谢谢

Answer 1

如果我发布无效选项，我可以以完全相同的方式使测试失败。发布 Bronze 会通过测试，但我在form类中选择了硬编码，并且不会从数据库中动态获取它们。

让我想一想，如果计划存在于单元测试的数据库中（或者在模拟的queryset中），那么它们是从Plan.objects.get_choices()正确获取的吗？
