Can't build index for solr/haystack: unknown f

问题:

I'm trying to follow along the haystack tutorial. I run into an error when I run manage.py rebuild index

I get the following error:

WARNING: This will irreparably remove EVERYTHING from your search index.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.

I did run manage.py build_solr_schema > ~/solr-4.2.1/example/solr/conf/schema.xml

I had to create the conf directory manually as it did not exist. I noticed the tutorial uses Solr 3 while I'm on 4. Did the location of the conf dir change perhaps?

回答1:

The problem is with the Solr (haystack document use v3.5.0, here you may be using the latest) not finding the configuration file. These 3 steps worked for me

• Place the schema in solr-x.y.z/example/solr/collection1/conf/schema.xml

• In the schema change stopwords_en.txt to lang/stopwords_en.txt

• Add the version field (as mentioned below) to the schema in the fields section

  <field name="_version_" type="long" indexed="true" stored="true" multiValued="false"/>

This is more of a comment, but due to my lack of points I am unable to comment...

Has anyone figure out a soltuion to this? I'm having the exact same problem. The field is being created in schema.xml as such:

<field name="django_id" type="string" indexed="true" stored="true" multiValued="false"/>

I have restarted Solr (multiple times), and I am 100% positive my schema.xml code is correct. What the heck is going on here?

EDIT: I switched to Elasticsearch and have no problems. However, I'm sure others out there would find help to this question useful.

I had to clone the haystack source code and do some hacks as follows :

In the /haystack/management/commands/build_solr_schema.py , I commented DJANGO_ID in the build_context() func. Then in /haystack/templates/search_configuration/solr.xml , I replaced {{ DJANGO_ID }} with "django_id" and everything worked ok.

I think the {{DJANGO_ID}} is not being replaced with "django_id" when you generate schema.xml.
