liferay indexer hook

post processor indexer HookIndexer hook implements a post processing system on top of the existing indexer.

For example go to Users and Organizations and search based on type.

You wont get the result based on type.

To achieve this just follow the below steps.

Step 1 :

Create a liferay project and choose plugin type as hook and finish.

Step 2 :

Modify in liferay-hook.xml

<?xml version="1.0"?>

<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.1.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_1_0.dtd">

<hook>

<indexer-post-processor>

<indexer-class-name>com.liferay.portal.model.Organization</indexer-class-name>

<indexer-post-processor-impl>com.javaeasyforu.MyCustomPostIndexer</indexer-post-processor-impl>

</indexer-post-processor>

</hook>

Step 3 :

create a package and java class

docroot/WEB-INF/src  ---->create a class as MyCustomPostIndexer

package com.javaeasyforu;

import com.liferay.portal.kernel.search.BaseIndexerPostProcessor;

import com.liferay.portal.kernel.search.Document;

import com.liferay.portal.kernel.search.Field;

import com.liferay.portal.model.Organization;

public class MyCustomPostIndexer extends BaseIndexerPostProcessor 

{

public void postProcessDocument(Document document, Object object)throws Exception {

  Organization orgEntity = (Organization) object;

  String indexerOrgTitle = null;

  try 

  {

    indexerOrgTitle = orgEntity.getType();

  }

  catch (Exception e) 

  {

    e.printStackTrace();

  }

  if (indexerOrgTitle.length() > 0)

  {

    document.addText(Field.TITLE, indexerOrgTitle);

  }

 }

}

Step 4 : Right click on project and deploy

Now go to control panel and click on Users and Organizations

Step 5 :

Search for Type and see the result

Note : It will effect only for new and update records but not for existing records. So edit for some organization and check the result.

Key Point :

Eclipse is not opening properly

# A fatal error has been detected by the Java Runtime Environment 

#

# SIGSEGV (0xb) at pc=0x00007f8e88aaa2a1, pid=7607, tid=140252668163840

Solution: After extracting eclipse you have file called config.ini inside configuration folder. Go there and add the below line at the end

org.eclipse.swt.browser.DefaultType=mozilla

difference between hook and ext

Hook                                                          EXT

Hot Deployable                                                    Not Hot Deployable

No need to Restart the server                              Need to restart the server

Maintenance is Easy                                           Maintenance is difficult

Not overriding code directly                                It will replace the code directly

Undoing is easy                                                   Undoing is difficult

Note : We can deploy only one ext plugin per Liferay installation.

Key Point : To avoid multiple submit in form submission when it got refresh give the below line in  liferay-portlet.xml

<action-url-redirect>true</action-url-redirect>

Liferay Custom Icons

In Liferay Search Container if you want to call your own image you can define as

<liferay-ui:search-container-column-text name="Cancel">

          <liferay-ui:icon image="my-custom-icon"  src="/PortletName/images/cancel.png" />

</liferay-ui:search-container-column-text>

copy your image in images folder and provide the path.

Key Point : If you want to reuse your custom portlet more than one time please give the below line in liferay-portlet.xml 

<instanceable>true</instanceable>

Key Point : In liferay service builder if there is no primary key it will throw java.lang.RuntimeException there is no primary key for entity EntityName

liferay user related tables

If we create User in Liferay the following tables will effect in DB

                  

        Contact_                          

         User_                               

         Users_Roles                    

       The above three  tables will effect in Data Base once if we create User .

       

         Along with these options we have some more options for user.

             Table Name                            Options for  User if we go to control panel

             Address                                                       Addresses

              Phone                                                         Phone Numbers

             Website                                                       Websites

            

             EmailAddress                                             Additional Email Addresses

             Contact_                                                      Social Network

            (facebookSn,twitterSn,mySpaceSn)

             Contact_                                                      sms

            (smsSn)

             User_                                                           openId

           (openId)

            AnnouncementsDelivery                             Announcements

             User_                                                           DisplaySetting

           (languageId, timeZoneId,greeting) 

             User_                                                           Comments

           (comments)

For Custom fields we have tables like ExpandoColumn,  ExpandoRow,  ExpandoTable and ExpandoValue.

Here if we have already custom fields we can give the values for those fields and save

Key Point : At what time table will create in liferay when we are using liferay service builder???

Once if we build the services all classes and interfaces will create but after deploying the portlet only the related  table will create in DataBase

Embedding custom portlet in Webcontent liferay

Create Web content and click on source.
Enter the below line

<p>

       <runtime-portlet instance="4433" name="portlet_name" querystring=""> </runtime-portlet>

</p>

how to get name---->Go to control panel---->Plugins Configuration---->copy plugin id and paste in the above line mentioned as name=" "

For Example :

<p>

       <runtime-portlet instance="4433" name="116" querystring=""> </runtime-portlet>

</p>

116 (Out of the box portlet Id)--------> Activities

Key Points : 

 If we want to generate a finder for primary key in liferay  service builder the return type should be an entity if return type is collection it will throw an error in persistance and util.java with error as Duplicate parameter columnName.
