Can I perform an upsert?

Is it possible to perform an upsert with fireo, and if so, could you provide a quick example of how to do so?

save() method work as upsert when first you are getting data and then update any field and save it will work as upsert otherwise if you provide same id with any other document then it will override the document.

class Tweet(Model):
    id = IDField()
    tweet = TextField()
    other_field = TextField()


t = Tweet()
t.id = 'id-123'
t.tweet = 'some tweet'
t.other_field = 'any value'
t.save()

# When save() method behave like upsert
t2 = Tweet.collection.get(t.key)
t2.tweet = 'tweet changed'
t2.save()

# When save() method behave like override
# In this case other_field will be None
t3 = Tweet()
t3.id = 'id-123'
t3.tweet = 'tweet changed'
t3.save()

Actually save() always override the document but when you first get() the document change any field and save it other fields are already containing the values so it look like upsert() method. if you print(t2) you will see the value of t2.other_field

t2 = Tweet.collection.get(t.key)
print(t2)
t2.tweet = 'tweet changed'
t2.save()

# This work same as
t2 = Tweet()
t2.id = 'id-123'
t2.tweet = 'some tweet'
t2.other_field = 'any value'
t2.save()

I’m not sure an upsert method is required, since the save() method effectively performs an upsert.
