Calling from_es with returned hits from a Search

My code:

MyDocType.from_es(Search(index='mydoctype').query('match', name=hit_name).execute().hits[0])

I see that the source for from_es uses the variable hit, so I assume it expects to be passed in a hit. This is apparently wrong since I get an attribute error; hit has no attribute copy().

Seems like this is a useful usecase (at least for me), is there a recommended way of doing this sort of thing? Would you be open to a MR to add that if not?

I am wondering why you are doing this instead of just MyDocType.search().query('match', name=hit_name).execute().hits[0] which will already give you an instance of MyDocType?

The from_es method is a low level method to construct the object from the raw dictionary, not the already pre-parsed Hit object. If you want to use it with Hit you will have to refer to the raw response by doing .execute().to_dict()['hits']['hits'][0]

Hope this helps!

The problem is that ContactIndex (or even MyDocType) is looking for index called some-alias but the returning documents are tagged with the name of their actual index so it doesn’t match.

The _matches classmethod needs to be implemented in that case, as per the example (0)

Hope this helps!
