[jira] [Created] (SOLR-10865) parameter processor=Template doesn't invoke TemplateUpdateProcessorFactory.

[Amrit Sarkar (JIRA)]

Amrit Sarkar created SOLR-10865:
-----------------------------------

             Summary: parameter processor=Template doesn't invoke 
TemplateUpdateProcessorFactory.
                 Key: SOLR-10865
                 URL: https://issues.apache.org/jira/browse/SOLR-10865
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: update
    Affects Versions: master (7.0)
            Reporter: Amrit Sarkar


Ref docs::

{quote}
The TemplateUpdateProcessorFactory can be used to add new fields to documents 
based on a template pattern.
This can be used directly in a request without any configuration. To enable 
this processor, use the parameter processor=Template.

Sample curl::

{code}
curl -X POST -H 'Content-Type:application/json' 
'http://localhost:8983/solr/gettingstarted/update/json/docs?processor=Template&Template.field=fullName_s:AmritSarkar&commit=true'
 --data-binary '{"id": 1,"title": "titleA"}'
{code}

I am receiving exception::
{code}

I looked into how the testclass has been created::

TemplateUpdateProcessorTest::
{code}
  public void testSimple() throws Exception {
    AddUpdateCommand cmd = new AddUpdateCommand(new LocalSolrQueryRequest(null,
        new ModifiableSolrParams()
            .add("processor", "Template")
            .add("Template.field", "id:${firstName}_${lastName}")
            .add("Template.field", "another:${lastName}_${firstName}")
            .add("Template.field", "missing:${lastName}_${unKnown}")
    ));
    cmd.solrDoc = new SolrInputDocument();
    cmd.solrDoc.addField("firstName", "Tom");
    cmd.solrDoc.addField("lastName", "Cruise");

    new TemplateUpdateProcessorFactory().getInstance(cmd.getReq(), new 
SolrQueryResponse(), null).processAdd(cmd);
    assertEquals("Tom_Cruise", cmd.solrDoc.getFieldValue("id"));
    assertEquals("Cruise_Tom", cmd.solrDoc.getFieldValue("another"));
    assertEquals("Cruise_", cmd.solrDoc.getFieldValue("missing"));
  }
{code}

*There is no test to check whether _processor=Template_ works or not*, 
TemplateUpdateProcessorFactory() object is EXPLICITLY created to getInstance 
and do processing on the updates.
