ImageField not working for Django version 2.0.4

I am using Django version 2.0.4 but I am facing a problem with models.ImageField.

models.ImageField

Whenever I try to update an existing image with a new one, nothing happens. Also when I try to clear the image, nothing happens.
I have all the dependencies installed like Pillow.

I have declared my ImageField as usual like -

class Community(models.Model):
image = models.ImageField(
upload_to=upload_location,
null=True,
blank=True,
width_field="width_field",
height_field="height_field", help_text="A image representing the Community")
height_field = models.IntegerField(null=True, blank=True)
width_field = models.IntegerField(null=True, blank=True)

def __str__(self):
return str(self.id)


I have used ImageField before, but haven't ever faced such an issue ever. Is this a problem with the Django version? Should I consider upgrading my Django version?
Thanks in advance

Things I have tried -
I have tried a different database.
Tried upgrading the Pillow version

You can upload or update an image in Django the following way:

models.py file

class ImageModel(models.Model):
image = models.FileField(upload_to="profile pics/", null=True, blank=True)


image.html file

<form method="post" enctype="multipart/form-data">
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>


This is how I used to upload / update images in my project.

Hope things work well. Cheers!

I figured out what the problem was. I did implement the save method in the admin.py as

def save_model(self, request, obj, form, change):
if change:
obj.updated_by = request.user
else:
obj.created_by = request.user
obj.updated_by = request.user
obj.save()


which was causing the problem. I fixed it by calling the save_model of the super class like this -

def save_model(self, request, obj, form, change):
super().save_model(request, obj, form, change)
if change:
obj.updated_by = request.user
else:
obj.created_by = request.user
obj.updated_by = request.user
obj.save()


I know I should have called this function before, but it was a good learning for me to call it everytime necessary
