[Solved]-How can I upload svg file to a django app?


You sould change your Django ImageField to FileField and add .svg extension to field validators.

File Extension Validator

The result model file field is something like this:

from django.core.validators import FileExtensionValidator

news_img = models.FileField(upload_to="pictures/%Y/%m/", validators=[FileExtensionValidator(['pdf', 'doc', 'svg'])])


Create your own field like this:

import sys
from io import BytesIO
from PIL import Image
import xml.etree.cElementTree as et

from django.core.exceptions import ValidationError
from django.forms import ImageField as DjangoImageField
from django.utils import six

class SVGAndImageFormField(DjangoImageField):

    def to_python(self, data):
        Checks that the file-upload field data contains a valid image (GIF, JPG,
        PNG, possibly others -- whatever the Python Imaging Library supports).
        test_file = super(DjangoImageField, self).to_python(data)
        if test_file is None:
            return None

        # We need to get a file object for Pillow. We might have a path or we might
        # have to read the data into memory.
        if hasattr(data, 'temporary_file_path'):
            ifile = data.temporary_file_path()
            if hasattr(data, 'read'):
                ifile = BytesIO(data.read())
                ifile = BytesIO(data['content'])

            # load() could spot a truncated JPEG, but it loads the entire
            # image in memory, which is a DoS vector. See #3848 and #18520.
            image = Image.open(ifile)
            # verify() must be called immediately after the constructor.

            # Annotating so subclasses can reuse it for their own validation
            test_file.image = image
            test_file.content_type = Image.MIME[image.format]
        except Exception:
            # add a workaround to handle svg images
            if not self.is_svg(ifile):
                six.reraise(ValidationError, ValidationError(
                ), sys.exc_info()[2])
        if hasattr(test_file, 'seek') and callable(test_file.seek):
        return test_file

    def is_svg(self, f):
        Check if provided file is svg
        tag = None
            for event, el in et.iterparse(f, ('start',)):
                tag = el.tag
        except et.ParseError:
        return tag == '{http://www.w3.org/2000/svg}svg'
