python - How to add countless identical fields to a model?

Question

I have a model and want to add pictures describing it. The number of pictures is not fixed. Is there any way other than association?

Answer 1

Stored using mongodb, the attribute fields of each record are dynamic and can be added or deleted as you like. For specific examples, please refer to the dynamic attributes of e-commerce products, different sizes, colors, etc.

Answer 2

If you don’t want to be related, you must have redundant fields
