What is the efficient way to check if kwargs are valid then pass them accordingly?

Question

I have the following code and what I need to do is to check if either status, issue, owner and mantis_id are valid (not empty). According to the validity result I pass all those that are valid as kwargs to a function called upsert().

form=ticket_form()
status=request.form['status']
issue=request.form['ticket_issue']
owner=request.form['owner']
mantis_id=request.form['mantis_id']

Here is the second part where I pass those arguments that are valid as kwargs:

cur.execute(upsert('tbl_tickets', status=status, issue=issue, owner=owner))
connect.commit()

I can check each of them individually but I was wondering if there is a more efficient/compact way that I can use. Thanks.

Answer 1

You can do something like this:

all_args = dict(
    form=ticket_form()
    status=request.form['status']
    issue=request.form['ticket_issue']
    owner=request.form['owner']
    mantis_id=request.form['mantis_id']
)
valid_args = {k: v for k, v in all_args.items() if v}
cur.execute(upsert('tbl_tickets', **valid_args))
