Question

我想测试我的imageform，我提供所有必需的数据，但它仍然给我一个错误。有谁知道，如何测试表单的ImageField？

我的模特是

class Image(CustomModel):

    path = models.ImageField(_('Path'), upload_to=get_file_path,
                             help_text=_('Represents a path of an image.'))

    caption = models.CharField(_('Caption'), max_length=128,
                               null=False, blank=False,
                               db_column='caption',
                               help_text=_('128 characters max.')

    meta_info = models.TextField(_("Image MetaInfo"), null=False, blank=False,
                                help_text=_('Image meta info'),
                                default='{}', db_column='meta_info')

    created_at = models.DateTimeField(_('Created At'), null=False,
                                      db_column='created_at', blank=False,
                                      help_text=_('Date time at which image was created.'),
                                      default=datetime.now())

我的表格：

class ImageForm(forms.ModelForm):
    class Meta:
            """
            Meta class for Image form
            """
            model = Image
            fields = ('caption', 'path', 'status','meta_info')
            widgets = {
                'meta_info': forms.HiddenInput(),
            }

class ImageForm（forms.ModelForm）：

我的测试方法：

def test_form_valid(self):
            """
            """
            self.tmp_dir = tempfile.mkdtemp()
            path = os.path.join(self.tmp_dir,"a376140b-054f-4329-82e1-f271af5cfcaf.png")
            form = ImageForm({'caption':'image', 'path':path, 'status':'A', "created_at":timezone.now(),
                             'meta_info':"{\"id\":2,\"type\":\"Q\",\"lang_id\":1}"})
            print(form.is_valid())
            print(form.errors)
            assert form.is_valid(), 'should be valid'

回溯：

   def test_form_valid(self):
        """
            """
        self.tmp_dir = tempfile.mkdtemp()
        path = os.path.join(self.tmp_dir,"a376140b-054f-4329-82e1-f271af5cfcaf.png")
        form = ImageForm({'caption':'image', 'path':path, 'status':'A', "created_at":timezone.now(),
                         'meta_info':"{\"id\":2,\"type\":\"Q\",\"lang_id\":1}"})
        print(form.is_valid())
        print(form.errors)
>       assert form.is_valid(), 'should be valid'
E       AssertionError: should be valid
E       assert False
E        +  where False = <bound method BaseForm.is_valid of <ImageForm bound=True, valid=False, fields=(caption;path;status;meta_info)>>()

我尝试过测试imagefield的解决方案，但这对我不起作用。有谁知道如何测试imagefield？

Answer 1

应该是：

from django.core.files.uploadedfile import SimpleUploadedFile
....
data = {'caption':'image', 'status':'A', "created_at":timezone.now(), 'meta_info':"{\"id\":2,\"type\":\"Q\",\"lang_id\":1}"}
form = ImageForm(data, {'path':SimpleUploadedFile('filename.png', 'data')})

因此，当您尝试使用表单绑定文件数据时，应始终将文件信息放入UploadedFile对象中，并使用两个参数构建表单。

here是Django Doc

的例子
