django-haystack-solr-commands 0.1

django management command 'solr' all-in-one for Solr 5

Solr 5.0.0 is easy to deploy with cloud Cores and automatic managed-schema but no more schema.xml file to copy.

Solr 5.0.0 can edit a core's configuration via with the Schema REST API.

Solr 5.0.0 breaked Haystack version 2.3.1 because it uses managed-schema by default and removes the need to copy a schema.xml file.
It also provide a ``bin/solr`` command that start and a Solr daemon service, or administrate the Cores.

This what the  ``manage.py solr`` command provided by this Django App

longer supported: BCDIntField, BCDLongField, BCDStrField, IntField, LongField,
FloatField, DoubleField, SortableIntField, SortableLongField, SortableFloatField,
SortableDoubleField, and DateField. Convert these types in your schema to the
