I'm trying to integrate Haystack with Solr. When I try to build the index, I get an error "Unknown field django_id" from SOLR. What's causing this to happen?

You also get this error if you haven't given Solr the schema.xml file which Haystack generates for you, as explained here in the docs.

    After I placed my schema in the conf dir, I had to restart solr to get it to work. BTW, the conf dir is apache-solr-3.5.0/example/solr/conf. – Amjith Feb 06 '12 at 13:50
  • restarting solr was key for me, i tried different versions of haystack and a bunch of wierd ass configurations to no avail. one restart and everything started working. ::facepalm:: – Francis Yaconiello Jun 15 '12 at 14:51
  • the link above does not work anymore this one is up to date: http://django-haystack.readthedocs.io/en/latest/tutorial.html#reindex – matyas Oct 20 '16 at 15:34

The schema.xml was malformed as I had copied additional text from the console.

If you added new fields to your database and copied the generated XML files from Haystack, you might also be getting this error because you haven't restarted jetty/Tomcat/whatever server you are using. This solved it for me on Ubuntu and Jetty:

sudo /etc/init.d/jetty stop
sudo /etc/init.d/jetty start

(by the way, that would also be the same as simply doing this):

sudo service jetty restart

Or, if you are using tomcat, that would be 

sudo service tomcat6 restart

Edit: (tested this with Tomcat, and it solved the same problem again, the same as with Jetty).
