Duplicate, copy the values from the first row (model table) for N number of rows?

I have a Django model table.

In which the content is only one - the first row of the table.

But I need to duplicate - this first single row.

I need to fill 20 (for example, N number of rows of the model table) with the same values as from the first row of the model table.

How can you duplicate, copy the values from the first row (model table) for N number of rows?

You can use for loop to insert more records in database
