how to use bulk save

elasticsearch version 1.4.2 elasticsearch-dsl-py version 0.0.11

elasticsearch-dsl-py is to support bulk save? how can I use bulk save with elasticsearch-dsl-py

[j2kun]

For example, if I were to make a base class that looks like this:

class DocumentBase(DocType):
    @classmethod
    def bulk_save(cls, dicts):
        objects = (cls.create(d).to_dict(include_meta=True) for d in dicts)
        client = connections.get_connection()
        return bulk(client, objects)

How would I change this to do a bulk update/delete, or do bulk get’s in general?

@j2kun update/delete can use _op_type, it’s like

from elasticsearch_dsl.connections import connection
from elasticsearch.helpers import bulk

bulk(connection.get_connection(), (dict(d.to_dict(True), **{'_op_type': 'update'}) for d in DOCUMENTS))

upsert is like this

from elasticsearch_dsl.connections import connection
from elasticsearch.helpers import bulk

def upsert(doc):
    d = doc.to_dict(True)
    d['_op_type'] = 'update'
    d['doc'] = d['_source']
    d['doc_as_upsert'] = True
    del d['_source']

    return d

bulk(connection.get_connection(), (upsert(d) for d in DOCUMENTS))
