I am using Django Imagekit in models.py:
from imagekit.models import ProcessedImageField
class AltroUser(models.Model):
first_name = models.CharField(_('first name'), max_length=30)
image = ProcessedImageField(upload_to='media/path',
default='user_default.jpg',
processors=[ResizeToFill(640, 640)],
format='JPEG',
options={'quality': 60})
serializers.py:
class UserRegistrationSerializer(Serializer):
first_name = serializers.CharField()
image = serializers.ImageField()
I am trying to test the image field. I have tried following methods:
def get_test_image():
try:
image = DjangoFile(open(os.path.join(django_settings.MEDIA_ROOT, 'user_default.jpg'),
mode='rb'))
return image
except (OSError, IOError) as e:
return None
def get_test_image1():
file = io.BytesIO()
image = Image.new('RGBA', size=(100, 100), color=(155, 0, 0))
image.save(file, 'png')
file.name = 'test.png'
file.seek(0)
return SimpleUploadedFile('abc.jpg', file.read())
def get_test_image2():
path = os.path.join(django_settings.MEDIA_ROOT, 'user_default.jpg')
file = File(open(path, 'r+b'))
return SimpleUploadedFile('abc.jpg', file.read())
I have tried calling the above three methods to set the value of the image key but none of them worked. For get_test_image()
, I get a response "The submitted file is empty."
For get_test_image1()
and get_test_image2()
, I get a response "The submitted file is empty."
with an exception before in the data image field '_io.BytesIO' object has no attribute 'encoding'
.
I don't understand what am I missing. Please help.
Here's an example of what I'm using to generate test image:
from StringIO import StringIO
from PIL import Image
from django.core.files import File
def get_image_file(name='test.png', ext='png', size=(50, 50), color=(256, 0, 0)):
file_obj = StringIO()
image = Image.new("RGBA", size=size, color=color)
image.save(file_obj, ext)
file_obj.seek(0)
return File(file_obj, name=name)
