Model.last() returns list

[dvnstrcklnd]

The Model.last() method returns a list. It seems like it should return a single object.

last_sample = session.Sample.last()
print("{}: {}".format(last_sample.name, last_sample.description))

produces

Traceback (most recent call last):
  File "load_samples.py", line 11, in <module>
    print("{}: {}".format(last_sample.name, last_sample.description))
AttributeError: 'list' object has no attribute 'name'

I would also expect Model.last to return a single object. I can change things so it does, but, in the interim, there is also a "one" method you can call that will return the last item.

last_sample = session.Sample.one()
print("{}: {}".format(last_sample.name, last_sample.description))

The way it is now, .last(n) was intended to always return a list, but it doesn't have to be that way, so it may make sense to change it to

• Sample.last() - return last Sample (or None if there are no Samples) -Sample.last(1) - return last Sample as a list
• Sample.last(10) return last 10 Samples as a list
• Sample.first() - return first Sample (or None if there are no Samples)
• Sample.first(1) - return first Sample as a list
• Sample.first(10) return first 10 Samples as a list
