如何在Django中测试未选中的复选框？

因此，我向用户显示了一个复选框，您可以在我的

forms.py

文件中看到：

class AddFooToBarForm(forms.Form):
    to_original = forms.BooleanField(initial=True,
                                     error_messages={'required':
                                                         "Oh no! How do I fix?"})
    ...

def add_foo_to_bar(request, id):
    ...
    try:
        bar = Bar.objects.get(pk=id)

        if request.method == 'POST': # handle submitted data
            form = AddFooToBarForm(bar, request.POST)
            if form.is_valid(): # good, now create Foo and add to bar
                ...
                to_original = form.cleaned_data['to_original']
                print 'to original is {0}'.format(to_original) # for debugging
                if to_original:
                    # do A
                else:
                    # do B

                ...

class FooTest(TestCase):
    ...

    def test_submit_add_to_Bar(self):
        form_data = {
            ...
            'to_original': True,
        }
        response = self.client.post(reverse('add_foo_to_bar', args=(self.bar.id,)),
                                    form_data, follow=True)
        self.assertContains(...) # works

        ...

        form_data['to_original'] = None
        response = self.client.post(reverse('add_foo_to_bar', args=(self.bar.id,)),
                                    form_data, follow=True)
        print response # for debugging purposes
        self.assertContains(...) # doesn't work

根据用户是否选中该复选框，我会执行不同的操作，正如您在我的

views.py

文件中看到的：

class AddFooToBarForm(forms.Form):
    to_original = forms.BooleanField(initial=True,
                                     error_messages={'required':
                                                         "Oh no! How do I fix?"})
    ...

def add_foo_to_bar(request, id):
    ...
    try:
        bar = Bar.objects.get(pk=id)

        if request.method == 'POST': # handle submitted data
            form = AddFooToBarForm(bar, request.POST)
            if form.is_valid(): # good, now create Foo and add to bar
                ...
                to_original = form.cleaned_data['to_original']
                print 'to original is {0}'.format(to_original) # for debugging
                if to_original:
                    # do A
                else:
                    # do B

                ...

class FooTest(TestCase):
    ...

    def test_submit_add_to_Bar(self):
        form_data = {
            ...
            'to_original': True,
        }
        response = self.client.post(reverse('add_foo_to_bar', args=(self.bar.id,)),
                                    form_data, follow=True)
        self.assertContains(...) # works

        ...

        form_data['to_original'] = None
        response = self.client.post(reverse('add_foo_to_bar', args=(self.bar.id,)),
                                    form_data, follow=True)
        print response # for debugging purposes
        self.assertContains(...) # doesn't work

因此，我想测试我的站点是否确实执行了正确的操作，这取决于用户是否在我的

tests.py

文件中选中复选框：

class AddFooToBarForm(forms.Form):
    to_original = forms.BooleanField(initial=True,
                                     error_messages={'required':
                                                         "Oh no! How do I fix?"})
    ...

def add_foo_to_bar(request, id):
    ...
    try:
        bar = Bar.objects.get(pk=id)

        if request.method == 'POST': # handle submitted data
            form = AddFooToBarForm(bar, request.POST)
            if form.is_valid(): # good, now create Foo and add to bar
                ...
                to_original = form.cleaned_data['to_original']
                print 'to original is {0}'.format(to_original) # for debugging
                if to_original:
                    # do A
                else:
                    # do B

                ...

class FooTest(TestCase):
    ...

    def test_submit_add_to_Bar(self):
        form_data = {
            ...
            'to_original': True,
        }
        response = self.client.post(reverse('add_foo_to_bar', args=(self.bar.id,)),
                                    form_data, follow=True)
        self.assertContains(...) # works

        ...

        form_data['to_original'] = None
        response = self.client.post(reverse('add_foo_to_bar', args=(self.bar.id,)),
                                    form_data, follow=True)
        print response # for debugging purposes
        self.assertContains(...) # doesn't work

我试过了

• del form_data['to_original']

  ——这会显示“哦，不！我该如何修复？”错误消息

• form_data['to_original']=None

  ——在我的视图函数中，我得到了

  True

  ，因此完成了A而不是B

• form_data['to_original']=False

  ——这会再次显示“噢，不！我该如何修复？”错误消息

---

那么，我应该如何测试没有选中Django中复选框的用户呢？（我使用的是最新版本1.4.3）

如果未选中复选框，则它不会以提交的形式出现。此外，当提交的值为

'on'

时

如果要使

BooleanField

可选，请在定义表单字段时将

required=False

---

.

啊，谢谢！我通过检查

to_original

是否是一个键来实现它
