Using python shell, how do I associate an image with an ImageField in a class (Django)

Okay so I added a field to a model called college.

Here is the new field:

logo = models.ImageField(upload_to="logos", default="static/images.default.png")

So I have a few images in my media folder, but how do I associate them with certain images in the class.

Would I say Harvard.logo = ?

Would the ? be the image path. What exactly is the image path? Using Pillow.

Address of the ImageField type starts by MEDIA_ROOT path and then directory that determined in upload_to parameter, also on the db save path similar upload_to_dir/file_name.ext format. Your default parameter must start with uploat_to value, change this similar below:

logo = models.ImageField(upload_to="logos", default="logos/images.default.png")

And for select an image that is related to college value you can override save method of your model:

class MyModel(models.Model):
    logo = models.ImageField(upload_to="logos", default="logos/images.default.png", blank=None)
    college = models.IntegerField(choices=[(1, 'Harvard'), (2, 'MIT'), (3, 'Oxford')])

    def save(self, *args, **kwargs):
        if self.logo is None:
            if self.college == 1:
                self.logo = 'logos/Harvard.png'
            if self.college == 2:
                self.logo = 'logos/MIT.png'
            if self.college == 3:
                self.logo = 'logos/Oxford.png'

        super(MyModel, self).save(*args, **kwargs)

Notice: These default images must already exists in logos directory or copy to this.
