Django: Multiple models on the same table
I am building a recipe/cookbook application (something like cookpad or allrecipes) for a personal project.
I have a model for image like so:
class Image(Model):
type = (("R", "Recipe"), ("P", "Profile"),
("E", "Embedded"), ("B", "Base"))
name = models.CharField(max_length=55)
type = models.CharField(choices=type, max_length=1, default="B")
image = VersatileImageField(
upload_to=FileNameGenerator(prefix="images"),
placeholder_image=OnDiscPlaceholderImage(
path=join(settings.MEDIA_ROOT, "images", "default.jpg")
),
null=True,
blank=True,
)
I want to use one table only to store all image. But store it to different place for each different type.
Example:
- Base image would be at images/xxx.jpg
- Profile's image at profiles/xxxx.jpg
- Recipe's image at recipes/xxx.jpg
- etc..
The only way I know how, is to make it an abstract model and extend it. But it would create many table (ProfileImage, RecipeImage, etc..)
If I use proxy I cannot change/override the behaviour of image field.
Is there a a way to extend models but save it to the same table in database?

You don't need separate models here. You just need a dynamic upload_to parameter - which you already seem to have, with FileNameGenerator. Why can't you extend that to use different directories as well as filenames?
