First of all, notice that each time you write:

Filter out spaces, ruby-- > str.strip and squery== > $.trim (str)

Then note:

Note the handling of duplicate fields:

First be clear about what can be repeated and what can't be repeated.

Repetition should also include some judgment on the combined primary key.
