Hello, I have a scenario where I want to save a author image and book image to assets table… I am using a polymorphic association. And author\_name is inside the books table. now when I save the image the imageable\_type says “Book” for both. And off-course it’s a correct behavior, but I am just trying to figure out is there any way where I can save author image and imageable\_type should have “AuthorImage” and it should call the same Book model Solution: Other solution I am thinking to separate the Author from book and have it in another table. Please it will be really helpful if someone can help me out. Thanks abhis ---

I think you're adding only book\_images and no author\_images at all. But I'm nbot sure, because you're not providing your code Try something like this: @asset.imageable = @author or AuthorImage.create attributes I don't know if you made the right decision with using polymorphic associations. You need to provide more information what your associations are. For example: Author has\_many Images OR Author has\_one image And can the image belong to a book and an author as well?
