Liferay- Formulario desde plantilla de velocity

Quería realizar un JournalArticle que contuviese una búsqueda, para ello necesitaba enviar un formulario desde velocity. Para ello:


## Accedemos al parametro que contiene la busqueda
#set($search = $request.parameters.search)

#set ($renderUrl = $request.get("render-url"))
#set ($namespace = $request.get("portlet-namespace"))
<form action="$renderUrl" method="post" name="${namespace}fm2">
<label for="search">Búsqueda: </label>
<input type="text" value="$!search" name="${namespace}search"/>
<input type="submit" value="Send"/>
</form>


Y si preferimos enviar el formulario usando el método "get" nos servirá para invocarlo desde la URL, la forma sería:


#set($search = $httpUtil.getParameter($httpUtil.decodeURL($request.attributes.CURRENT_URL), "search"))

#set ($renderUrl = $request.get("render-url"))
#set ($namespace = $request.get("portlet-namespace"))

<form action="$renderUrl" method="get" name="${namespace}fm2">
    <label for="search">Búsqueda: </label>
              <input type="text" value="$!search" name="search"/>

    <input type="submit" value="Send"/>
</form>


Acceder a servicios de Liferay desde plantilla de velocity

Existe 2 opciones

La primera necesita:

1. Usando el "liferay-ext", modificar el fichero "portal_ext.proporties" y cambiar la entrada: "journal.template.velocity.restricted.variables= " es decir no debe tener valor o al menos no contener "serviceLocator" con ello tendremos una variable que nos permite acceder a servicios de Liferay.
2. Si deseamos acceder a un servicio propio deberemos crearlo e insertalo usando "liferay-ext"
3. Finalmente para acceder: desde dentro de la plantilla:

   #set ($tagsService = $serviceLocator.findService("com.liferay.portlet.tags.service.TagsAssetLocalService"))
   #set ($journalArticleResourceService = $serviceLocator.findService("com.liferay.portlet.journal.service.JournalArticleResourceLocalService"))
   
   
   
   #set ($longGroupId = $getterUtil.getLong($groupId))
   #set ($articleResourcePK = $journalArticleResourceService.getArticleResourcePrimKey($longGroupId, $reserved-article-id.data))
   #set ($tagsAsset = $tagsService.getAsset("com.liferay.portlet.journal.model.JournalArticle", $articleResourcePK))
   #set ($tagsEntries = $tagsAsset.getEntries())
   
   Tags:
   #foreach( $entry in $tagsEntries )
   #set ($tag = $entry.getName())
   #if($velocityCount!=1), #end
   $tag
   #end

Con esa plantilla accemos a todos los tags del artículo actual y los escribimos.

La segunda alternativa no requiere modificar el fichero "portal_ext.properties" y consiste en:

#set ($tagsService = $portal.getClass().forName("com.liferay.portlet.tags.service.TagsAssetLocalServiceUtil").getMethod("getService", null).invoke(null, null))
#set ($journalArticleResourceService = $portal.getClass().forName("com.liferay.portlet.journal.service.JournalArticleResourceLocalServiceUtil").getMethod("getService", null).invoke(null, null))

Con ello accedemos también a los servicios.


Otro ejemplo, acceder al usuario que escribio el artículo e imprimir su nombre

#set ($userService = $serviceLocator.findService("com.liferay.portal.service.UserLocalService"))
#set ($user = $userService.getUserById($getterUtil.getLong($reserved-article-author-id.getData())))
$user.getScreenName()



Ejemplo propio


#set ($museumService = $serviceLocator.findService("com.muvac.service.MuseumLocalService"))


#set ($museum= $museumService.findById($museo.data))




Autor: ${autor.data}
Museo: ${museo.data}


Datos del museo

$museum.name
$museum.description
