django - default value name for the ForeignKey

[Aamu Padi]

I have a model for uploading photos in an album by the users. But if the user don't want to create an album, and just upload photos, I want it to be uploaded in a default album, namely 'Default album'. So that, whenever the user uploads photo without creating a new album, the 'Default album should be updated by that photos. For that, I thought about giving a default value in the title of the Album, but I also don't want to create a new album with name 'Default album' whenever the user doesn't create a new album to upload photo. I just want to update the 'Default Album'. Please suggest me how to achieve the above mentioned. And also is it okay to just give the ForeignKey field of the User to the Album class and not the Photo class??? Thank you!

models.py:

class Album(models.Model):
    title = models.CharField(max_length=200)
    pub_date = models.DateTimeField(default=datetime.now)
    user = models.ForeignKey(User)


class Photo(models.Model):
    album = models.ForeignKey(Album)
    title = models.CharField(max_length=200)
    image = models.ImageField(upload_to=get_upload_file_name, blank=True)
    pub_date = models.DateTimeField(default=datetime.now)

It’s more than ok to guive the user reference only to the Album. That is what is called normalization in the relational world.

About your first question, my solution is extract this logic from the model itself. I think it’s better to create a service object to do that.

Eg:

class PhotoManager(object):

    def __init__(user):

        self._user = user

    

    def add_photo(photo, album=None):

        if album is None:

            album = self._user.get_default_album()

        album.add_photo(photo)
