Printing out all fields of an entry. without knowing what they are.

Hello again friend! So I’m using the dsl library and i want to know if i can print out an entire entry from the response given. I’m using the following script to search a test instance.

import elasticsearch
from elasticsearch_dsl import Search, Q
from datetime import datetime

es = elasticsearch.Elasticsearch([{u'host': u'himanshu.addteq.com', u'port': b'9200'}])

es.index(index="david", doc_type="test-type", id=42, body={"any": "data", "timestamp": datetime.now()})

s = Search(using=es, index= "_all")
response = s.execute()
for hit in response:
        print hit

and I get this output.

<Result(logstash-2014.12.30/apache/F60rG4hiS42FKL-cx6rnTA): {u'tags': [u'_grokparsefailure'], u'@version': u'1', u'@time...}>
<Result(logstash-2011.08.30/apache/L_CO1AOSTnuvjiBKMl8T_g): {u'ident': u'-', u'referrer': u'"-"', u'@version': u'1', u'@...}>
<Result(logstash-2011.08.30/apache/YEXRqjFjSuOKE6cwLLg0Yw): {u'ident': u'-', u'referrer': u'"-"', u'@version': u'1', u'@...}>
<Result(logstash-2011.08.30/apache/l6QsZNmKQo-s9ZBOftlW4w): {u'ident': u'-', u'referrer': u'"-"', u'@version': u'1', u'@...}>
<Result(logstash-2011.08.30/apache/ONhdAJVhSJC5rfnKAvB78g): {u'ident': u'-', u'referrer': u'"-"', u'@version': u'1', u'@...}> 
...
<Result(logstash-2011.08.30/apache/MeGfj_LTSQWc6D8XugalAg): {u'ident': u'-', u'referrer': u'"http://www.semicomplete.com...}>

I can print the individual fields, like hit.host for example, but printing hit itself does not give me the entire set, I am only given these errors. Thanks again!

I see, is there any way to know if the response were empty?? this will re-create that issue

import elasticsearch
from elasticsearch_dsl import Search, Q
from datetime import datetime

es = elasticsearch.Elasticsearch([{u'host': u'himanshu.addteq.com', u'port': b'9200'}])

s = Search(using=es, index= "_all")

response = s.execute()
for hit in response:
    for field in hit:
        print 'Field %s contains:%r' % (field, hit[field])

@ChristopherRabotin just adding that you don’t need to work with the datetimes as text - elasticsearch-py supports datetime objects and will correctly serialize them when sending data to elasticsearch.
