Customizing the UserData property name mapping and search configuration

In this lesson, you modify the UserData field name mapping to map the new columns to the UserData field of the CatalogEntryView noun. You also create a search profile to return your custom data. As a result, the search results in your store can include the customer ratings data.

Procedure

Modify the user data field name mapping to map the customer ranking field to a user data.

Open IBM WebSphere Commerce Developer and switch to the Enterprise Explorer view.
Expand Search > xml > config > com.ibm.commerce.catalog-ext. If this directory does not exist, create the directory.
Open the wc-component.xml file for editing.
If this file does not exist, you must create this file. For more information, see Changing properties in the component configuration file (wc-component.xml) (WC EAR).

Add the following mapping into your file before the end of the </_config:valuemappingservice> element.


<_config:valuemapping externalName="CatalogEntryUserDataFieldNameMapping" internalName="CatalogEntryUserDataFieldNameMapping">
<_config:valuemap externalValue="x_customerRanking" internalValue="customerRanking_display" />
</_config:valuemapping>

If you created the file as part of completing this tutorial, your complete file can resemble the following code.


<?xml version="1.0" encoding="UTF-8"?>
<_config:DevelopmentComponentConfiguration
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.ibm.com/xmlns/prod/commerce/foundation/config ../xsd/wc-component.xsd "
xmlns:_config="http://www.ibm.com/xmlns/prod/commerce/foundation/config">

  <_config:valuemappingservice>
    <_config:valuemapping externalName="CatalogEntryUserDataFieldNameMapping" 
       internalName="CatalogEntryUserDataFieldNameMapping">
      <_config:valuemap externalValue="x_customerRanking" internalValue="customerRanking_display" />
    </_config:valuemapping>
  </_config:valuemappingservice>
</_config:DevelopmentComponentConfiguration>

Save your changes and close the file.

Modify the search configuration file so that the value of the customer ratings field can return in a new search profile.
1. In the com.ibm.commerce.catalog-ext directory, open the wc-search.xml file for editing.
  If this file does not exist, you must create this file. For more information, see Changing properties in the component configuration file (wc-component.xml) (WC EAR).
2. Add the following code to configure the new search profile for the customer ratings before the end tag of the file, </_config:search-config>.
```
<_config:profile name="IBM_findProductsBySearchTerm" indexName="CatalogEntry">
  <_config:query>  
    <_config:postprocessor 
    classname="com.ibm.commerce.foundation.server.services.rest.search.postprocessor.solr.SolrRESTSearchCatalogEntryViewUserDataQueryPostprocessor" />  
  </_config:query>   
  <_config:result>           
    <_config:field name="customerRanking_display"/>
  </_config:result>            
</_config:profile>
```
  - This code uses the IBM_findProductsBySearchTerm search profile.
  - This code adds the com.ibm.commerce.foundation.server.services.rest.search.postprocessor.solr.SolrRESTSearchCatalogEntryViewUserDataQueryPostprocessor postprocessor into the specified search profile. The purpose of this postprocessor is to populate and map UserData that is defined in the wc-componemt.xml file into the final catalog entry REST response.
  Note: Note: customerRanking_display is the example index field name that is used in this tutorial. Ensure that you add the index field name that you defined when you updated your search x-schema.xml file.
3. Save and close the file.
Restart the WebSphere Commerce Test Server.
To ensure that WebSphere Commerce picks up the changes that you made in this lesson and earlier lessons, you must restart the test server.
