[ScriptUpdateProcessor] Params aren't being picked up from solrconfig

Hi,

I'm trying to use the new ScriptUpdateProcessor in trunk with a simple
Python script. Everything seems to work nicely, but....
none of the params I specify in solrconfig.xml are being picked up. The
error I'm getting is: "NameError: global name 'params' is not defined".

Am I doing something wrong? Is this a bug?

I'd appreciate any help on this.

Rene

def processAdd(cmd):
    doc = cmd.solrDoc  # org.apache.solr.common.SolrInputDocument
    id = doc.getFieldValue('Identifier')
    logger.info('update-script#processAdd: id=' + id)

    # Get a configuration parameter
    to_field = params.get('to_field')
    doc.setField(to_field, doc.getFieldValue('abstract'))
    #logger.info('copy ' + from_field + ' to ' + to_field)

def processDelete(cmd):
    pass

def processMergeIndexes(cmd):
    pass

def processCommit(cmd):
    pass

Hi Rene,

Thanks for offering to help with wiki documentation.

You'll need to register on the wiki first, then tell us your wiki username, and we'll add you to ContributorsGroup, which will allow you to make edits.

I cannot believe I've looked over this :}
Thanks for helping me out. It works fine now.

I'd like to contribute to the wiki
page<http://wiki.apache.org/solr/ScriptUpdateProcessor>and add a
python example. So, if anyone could allow me write access or tell
me how to do this without, I'd be happy to contribute.

:   <updateRequestProcessorChain name="script">
:     <processor class="solr.StatelessScriptUpdateProcessorFactory">

:     </processor>

...that list of "params" isn't inside the <processor> tag, so 
StatelessScriptUpdateProcessorFactory doesn't know anything about it, so 
it's not passing it to the ScriptEngineManager
