DRF serializer remove imagefield absolute url

In DRF, now if i save the image the serializer is giving me the image with absolute path. But in my scenario, i don't want absolute path. I just need a image path which is there in DB. In my scenario, i'm hard-coding the image path in json. So i can't use the absolute path. Can anyone suggest some ideas to implement it.

Above answers are working for list and retrieve method, but i need to add for post and retrieve instead of querying and serializing it again. Below method will work.

Normally for ImageField and FileField will return name but in DRF it's been converted to url for usefulness. So u just need to change there that's it.

In your serailizer, just specify below like that:

Field_name = serializers.ImageField(use_url=False)

So this line will convert absolute url to name as response after Save and Update.

Create custom FileField will solve the issue

class CustomFileField(serializers.FileField):
    def to_representation(self, value):
        if not value:
            return None

        if not getattr(value, 'path', None):
            # If the file has not been saved it may not have a path.
            return None
        return value.path


class MyFooSerializer(serializers.ModelSerializer):
    my_file_field = CustomFileField()
    ...
    # other code

You can use SerializerMethodField. You can return the value as it is stored in the database by doing the following:

class YourSerializer(serializers.ModelSerializer):
    image = serializers.SerializerMethodField()

    def get_image(self, obj):
        return obj.image.file.name
