How to compare two image field properly

[Sencer Hamarat]

Hi,

I have two different models which include image fields individually.

Is there a proper way to compare those imagefileds?

class ModelA(models.Model):

    file = models.ImageField(

        verbose_name=_('File'),

        blank=False,

        null=False,
        max_length=400

    )

class ModelB(models.Model):

    image = ImageField(

        verbose_name=_('Product Image'),
        max_length=400,
        default=static('images/default_thumbnail.png'),
    )

Also, I need to figure out how to track any change in a single image field.

Regards,

Sencer HAMARAT

Thanks but, no.

I didn't mean the comparing content of the files.

one way that i know, not sure if best way to do it, 
but you could first extract the fields of your model as:

`modelAFields =  ModelA._meta.fields`

`modelBFields =  ModelB._meta.fields`

then extract your image field eg.:
`imageAField = modelAFields[0]`

`imageBField = modelBFields[0]`

then to display all the field's atributes and loop through them for comparing by :
`vars(imageAField)`
`vars(imageBField)`

If the image data is huge, that could take a long time.

Maybe you can just compare the checksum?
