How to Create dynamic field names using script transformers

Hi,

I am trying to generate a dynamic fieldname using custom transformers but
couldn't achieve the expected results.

My requirement is that I do not want to hardcode some of field names used by
SOLR for indexing, instead the field name should be generated using the data
retreieved from a table.

Any help on this regard is greatly appreciated.

Thanks,
Barani

Hey Erik,

Thanks a lot for your reply.. I am a newbie to SOLR ...

I am just trying to use the example present in Apache WIKI to understand
"how" the scriptTransformer works. I want to know how to pass the data from
table.field to transformer and get back the data from transformer and set
the value to any field.

    <dataConfig>
             <script><![CDATA[
                     function f1(row)        {
                         row.put('Hello', 'Test');
                         return row;
                     }
             ]]></script>
             <dataSource driver="com......." />

             <document>
                     <entity name="e" pk="id" transformer="script:f1"
query="select * from table1">
                     </entity>
             </document>
</dataConfig>


Basically I want a field like... <field column=”value”
name=”${elementpropertyvalue.propertyName}”/>
and index this field so that users can search on this dynamic field and get
the corresponding data also.


Thanks,
Barani

Barani -

Give us some details of what you tried, what you expected to happen,  
and what actually happened.

Re: How to Create dynamic field names using script transformers

To add some more details, this is what I am trying to acheive...

There are 2 fields present in a database table and I am trying to make those
2 fields as key value pair.

Eg: Consider there are 2 fields associated with each other (Propertyid and
propertyValue)

I want the property id as field name and property value as its field
value..something like...

<1111111>Test<111111111>

Thanks,
Barani
