How can I order, limit and filter in a single query using mongoengine

Question

try:    
     keyword = Keyword.objects[:1].order_by('-created_at').get(keyword='myfilterkeyword')
except Keyword.DoesNotExist as e:
     Logger.log(e)

For now I do it using the above way. Is this the optimal and right way to do it? Is exception handling the only way to detect missing data?

The correct way to do it in MongoEngine is:

keyword = Keyword.objects(keyword='myfilterkeyword').order_by('-created_at').first()

If there is no document with this keyword your variable keyword will be None.
