How to add dynamic attributes to a Django model?

Question

Django

Question like this - Django - what is the best way to bind multiple elements to the model (it is not known how many)?
But I would like to be able to set the data type of the field - number, string, time.
What is the best way to do this? Add a field with a data type (so that there is a select in the admin panel) + write custom validation depending on the data type and store everything in a CharField.
Or are there better ways? How well will Django-eav fit here and what are the pitfalls when working with it?

Answer 1

EAV is the only way this can be implemented. The pitfall is that EAV is always a sign that a relational database is being misused. Plus, it's damn slow.
