What's the proper way of using UUIDs?

[Francis Tseng]

I'm having trouble getting UUIDs working correctly with Sunburnt. I am receiving the error:

sunburnt.schema.SolrError: These required fields are unspecified:

 ['id']

I'm fairly new to Solr so I'm not completely sure where the issue lies, but I believe I have everything configured properly on the Solr end:

In my schema.xml, I have my id field and uuid fieldtype setup:

<fields>

  ...

    <field name="id" type="uuid" indexed="true" stored="true" required="true" multiValued="false" />

  ...

</fields>

<uniqueKey>id</uniqueKey> 

...

<types>

  ...

     <fieldType name="uuid" class="solr.UUIDField" indexed="true" />

  ...

</types>

Then, in solrconfig.xml I have:

  <requestHandler name="/update" class="solr.UpdateRequestHandler">

       <lst name="defaults">

         <str name="update.chain">uuid</str>

       </lst>

  </requestHandler>

    <!-- for generating unique ids -->

    <updateRequestProcessorChain name="uuid">

      <processor class="solr.UUIDUpdateProcessorFactory">

          <str name="fieldName">id</str>

      </processor>

      <processor class="solr.RunUpdateProcessorFactory" />

    </updateRequestProcessorChain>

I'm trying to add a document with Sunburnt like so:

   solr_interface.add({'text': 'some text'})

and then I receive the above error.

If I try specifying a uuid:

   solr_interface.add({'text': 'some text', 'id': '123' })

I get the error:

  ValueError: badly formed hexadecimal UUID string

Any help would be greatly appreciated!

Thanks,
