我正在为 Django 表单运行单元测试，form.is_valid() 不断返回 False，但我找不到错误。
这是 forms.py 的代码:
class CustomClearableFileInput(forms.ClearableFileInput):
template_name = 'forums/templates/clearable_file_input.html'
class NewQuestionForm(forms.ModelForm):
category = forms.ModelChoiceField(widget = forms.Select(attrs = {}),
queryset = FossCategory.objects.order_by('name'),
empty_label = "Select a Foss category",
required = True,
error_messages = {'required':'Select a category'})
title = forms.CharField(widget = forms.TextInput(),
required = True,
error_messages = {'required':'Title field required'},
strip=True)
body = forms.CharField(widget = forms.Textarea(),
required = True,
error_messages = {'required':'Question field required'},
strip=True)
is_spam = forms.BooleanField(required = False)
spam_honeypot_field = HoneypotField()
image = forms.ImageField(widget = CustomClearableFileInput(), help_text = "Upload image", required = False)
def clean_title(self):
title = str(self.cleaned_data['title'])
if title.isspace():
raise forms.ValidationError("Title cannot be only spaces")
if len(title) < 12:
raise forms.ValidationError("Title should be longer than 12 characters")
if Question.objects.filter(title = title).exists():
raise forms.ValidationError("This title already exist.")
return title
def clean_body(self):
body = str(self.cleaned_data['body'])
if body.isspace():
raise forms.ValidationError("Body cannot be only spaces")
if len(body) < 12:
raise forms.ValidationError("Body should be minimum 12 characters long")
body = body.replace(' ', ' ')
body = body.replace('<br>', '\n')
return body
class Meta(object):
model = Question
fields = ['category', 'title', 'body', 'is_spam', 'image']
这是tests.py的代码:
class NewQuestionFormTest(TestCase):
@classmethod
def setUpTestData(cls):
FossCategory.objects.create(name = 'TestCategory', email = '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="87e2ffe6eaf7ebe2c7e2ffe6eaf7ebe2a9e4e8ea" rel="noreferrer noopener nofollow">[email protected]</a>')
def test_too_short_title(self):
category = FossCategory.objects.get(name = "TestCategory")
title = 'shorttitlefsodzo'
form = NewQuestionForm(data = {'category': category, 'title': title, 'body': 'Test question body'})
self.assertTrue(form.is_valid())
这是我通过 print(form.errors) 得到的结果:
<ul class="errorlist"><li>category<ul class="errorlist"><li>Select a valid choice. That choice is not one of the available choices.</li></ul></li>
最佳答案
由于它是模型选择字段，因此请尝试使用类别的主键而不是实例本身。
form = NewQuestionForm(data = {'category': category.pk, 'title': title, 'body': 'Test question body'})
关于django - form.is_valid() 在 Django 单元测试中失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50872785/
