Hi guys, I've found the following functions to be commonly useful in
practice. Has anyone else written anything similar? Is there a better
idiom here, or better names or interfaces for these?
def get_one(query):
result = db(query).select()
assert len(result) <= 1, "GAH get_one called when there's MORE
than one!"
return result[0] if len(result) == 1 else None
def get_or_make_one(query, table, default_values):
result = get_one(query)
if not result:
table.insert(**default_values)
return get_one(query)
