How to transfer data from several models to one summary by the smallest size of one of the models?

Using Django Using the ORM
1

I have three databases - table models (Django Models ).

In which there is a different amount of data - a different number of rows of elements in the database table. One table has 100 rows - the other model table has 150 rows.

I’m going to migrate the data from these models to another one - a general summary table model. Sequentially transferring data from each model. How can I do this - to transfer data to the summary table - only by the size (number of rows) of the smallest model table?

What part of this process are you stuck on?

If it’s identifying how many rows are in a model, you can get the number of rows in a model using the count function.
