In the
Extending Share 1 blog entry, we created a share extension project. Now we will write code to add a 'new content' button to the document library section of Share, based on the code created in the
learning surf 1-6 blog entries.
NOTE: the complete sourceocde for this project can be downloaded from here.
We will create a ui web script to open a create content form. In the 'config/alfresco/site-webscripts' source folder in package 'com.orbitz.components.documentlibrary', add the following files:
create-content.get.desc.xml
<webscript>
<shortname>create-content</shortname>
<description>Create Content module primarily for Document Library</description>
<url>/components/documentlibrary/create-content</url>
</webscript>

</code></pre>
create-content.get.properties
## Titles
title=New Content
header=New Content Details
## Labels
label.name=Name
label.title=Title
label.description=Description
label.content=Content
To test the new form,
- Deploy the web script by running the 'deploy' an task. (Make sure that share was started at least once so that the share war is expanded in the webapps/share directory of tomcat, and that the APP_TOMCAT_HOME and TOMCAT_HOME is properly set. This will copy the web scripts to the share directory.
- Start tomcat
- Check the ui web script by going to the url http://localhost:8080/share/service/components/documentlibrary/create-content?htmlid which should render the form (without any CSS, though).
Step 2 - Create a new toolbar for Document Library adding the 'New Content' button
The document library toolbar will be modified to render the 'New Content' button linked to an action handler that will open the create-content form via the simple dialog mechanism. To do this, we will create a new toolbar component '/orbitz/components/documentlibrary/toolbar' that will augment the existing '/components/documentlibrary/toolbar' with minimal code replication. This is a bit dangerous since it is entirely possible that the document library toolbar will change over time, so perhaps overriding it in this way is not the best approach, however, I have tried to minimize the exposure to code change as much as possible. if others have a better approach, I would gladly accept it. The source for this new component will also be in the 'config/alfresco/site-webscripts' source folder in the 'com.orbitz.components.documentlibrary' package, with the following files:
toobar.get.desc.xml
This component description alters the url to '/orbitz/component/documentlibrary/toolbar' which will have to be mapped for the 'toolbar' the region of the documentlibary template.
<webscript>
<shortname>DocLib Toolbar</shortname>
<description>Document Library: Toolbar Component</description>
<url>/orbitz/components/documentlibrary/toolbar</url>
</webscript>

Step 3, create the javascript to support the toolbar

orbitz.toolbar.js
This javascript creates a new object: 'Alfresco.DocListOrbitzToolbar' instantiated in 'toolbar.get.html.ftl' that decorates the 'newContent' button as a YUI button mapped to the 'onNewContent' action handler to open the new-content form using the SimpleDialog mechanism

This script at first will be configured to run the web script to create a new folder:
var actionUrl = YAHOO.lang.substitute(Alfresco.constants.PROXY_URI + "slingshot/doclib/action/folder/site/{site}/{container}/{path}",
In the following steps, we will create our own script that will create a new file.
orbitz.toolbar.css
This css defines the images and style used for the 'newContent' button:
.toolbar .new-content button
{
background: transparent url(images/content-new-16.png) no-repeat 12px 4px;
padding-left: 32px;
}
.toolbar .new-content .yui-button-disabled button
{
background-image: url(images/content-new-disabled-16.png);
}
these images are copies of the slingshot project's 'source/web/components/images/edit-blog-16.png' image.
Step 4 - Create the component to map to the 'toolbar' region of the document library templateFinally in the 'config/alfresco/site-data' source folder in the 'components' package, we override the existing 'toolbar' region in the 'documentlibrary' template to reference the /orbitz/components/documentlibrary/toolbar' component:
template.toolbar.documentlibrary.xml<?xml version='1.0' encoding='UTF-8'?>
<component>
<scope>template</scope>
<region-id>toolbar</region-id>
<source-id>documentlibrary</source-id>
<url>/orbitz/components/documentlibrary/toolbar</url>
</component>
Step 5 - Deploy and TestFirst, we need to make sure the 'share' war is installed and expanded in the tomcat host. I use the Alfresco project build.xml's
ant incremental-slingshot-tomcat-exploded
But for a war distribtuion, just make sure it is run at least once.
To use the build.xml, make sure to set APP_TOMCAT_HOME and TOMCAT_HOME environment variables as recommended in the previous blog article:
Extending Share 1 - Creating a Share Extension ProjectTo build and deploy the share webapp expanded in the tomcat directory. Now we can deploy our extension code from the 'deals-share-extension' project's build.xml file:
ant deploy
This will create the 'deals-share-ext.jar' jar file and copy to the share/WEB-INF/lib directory, copy the configuration files from the config/alfresco/** source folders to the share/weB-INF/classes directory, and copy the web assets from the source/web source folders to the share root directory.
We can test our toolbar code directly using the url:
http://localhost:8080/share/service/orbitz/components/documentlibrary/toolbar?htmlid , but this will not render with CSS, and without CSS, the YUI components wont work.
Now we can test within the Share:
- Launch share http://localhost:8080/share, opens to the share dashboard
- Create and/or select a Site, opens to the site dashboard
- Select the 'document library' section should render our new toolbar with the 'New Content' button
- Press the 'New Content' button and the 'create-content' form should open
- Enter the new content's name, title, description and content int he form and press 'ok' and the dialog should close, but instead of a file created, we should see a new folder created. In the next steps we will create the web script necessary to create a new file.
Step 6 - Creating a custom web script actionNow we need to create a webscript service to use instead of the slingshot/doclib/action/folder service. for this blog, I will extend the action services to implement the following url pattern:
POST slingshot/doclib/action/file/site/{site}/{container}/{path}
To do this, we will add a new webscript service to the remote alfresco.war by uploading it to the Data Dictionary space. Later, we can separate this to our own amp module. As a starting point, we will copy the folder.post.* files to create file.post.* files in Remote API/config/alfresco/templates/webscripts/org/alfresco/slingshot/documentlibrary/action directory to create the following files:
- file.post.desc.xml
- file.post.json.ftl
- file.post.json.js
Now we can modify these files to do the work of creating a file instead of a folder. for 'file.post.desc.xml' we modify the url pattern to the following:
<webscript>
<shortname>folder</shortname>
<description>Document List Action - Create folder</description>
<url>/slingshot/doclib/action/file/site/{site}/{container}</url>
<url>/slingshot/doclib/action/file/site/{site}/{container}/{path}</url>
<format default="json">argument</format>
<authentication>user</authentication>
<transaction>required</transaction>
</webscript>
file.post.json.ftl will be changed, it imports the action.lib.ftl to create a standard results response json format. But I will combine the import. Its contents are the following:
<#macro resultsJSON results>
<#escape x as jsonUtils.encodeJSONString(x)>
{
"totalResults": ${results?size},
"overallSuccess": ${overallSuccess?string},
"successCount": ${successCount},
"failureCount": ${failureCount},
"results":
[
<#list results as r>
{
<#list r?keys as key>
<#assign value = r[key]>
<#if value?is_number || value?is_boolean>
"${key}": ${value?string}<#if key_has_next>,</#if>
<#else>
"${key}": "${value}"<#if key_has_next>,</#if>
</#if>
</#list>
}<#if r_has_next>,</#if>
</#list>
]
}
</#escape>
</#macro>
<@resultsJSON results=results />
file.post.json.js needs to be modified to handle a file instead of a folder.
The main changes I will make to this script:
- get a 'content' field from the json request object from the create-content form that we added previously.
if (!json.isNull("content"))
{
content = json.get("content");
}
- Rename variables folderName, folderDescription, folderTitle, folderPath to fileName, fileDescription, fileTitle, fileDescription and filePath respectively.
- Create a file node instead of a folder node
var fileNode = parentNode.createFile(fileName);
- set the content on the newly created fileNode variable arfter the fileNode.save(); method
fileNode.save();
// Add uifacets aspect for the web client
fileNode.content = content;
- Change messaging to reflect saving a file, not a folder.
The completed file.post.json.js looks like this:
/**
* Document List Component: action
*
* For a single-asset action, template paramters address the asset.
* For multi-asset actions, template parameters address the source or destination node,
* and a JSON body addresses the assets involved in the action.
* (note: HTTP DELETE methods must use URI)
*
* @param uri {string} site/{siteId}/{containerId}/{filepath} : full path to file or folder name involved in the action
* @param uri {string} node/{store_type}/{store_id}/{id}/{filepath} : full path to file or folder name involved in the action
*/
/**
* Main script entry point
* @method main
*/
function main()
{
// Params object contains commonly-used arguments
var params = {};
var files, rootNode;
if (url.templateArgs.store_type != undefined)
{

/* Bootstrap action script */
main();
This service uses the action.lib.js and action.lib.ftl libraries to simplify coding of similar functions, including: checkin, checkout, cancel-checkout, copy-to, move-to, file or folder delete and others. The action.lib.js is included in the folder.post.json.js script and provides a main() entry point to do common setup, clean up and host shared functions. The main entry point calls the runAction() function defined in the specific action script 'folder.post.json.js', effectively implementing a strategy pattern.
Step 7 - upload, build and testLog into the alfresco server as admin. Navigate to Company Home > Data Dictionary > Web Scripts > org > alfresco
Create a new directory 'doclib' and copy the three files in to this directory: 'file.post.desc.xml', 'file.post.json.ftl', and 'file.post.json.js'.
Navigate to
http://localhost:8080/alfresco/service/index and select 'refresh webscripts' button.
To view the new service, use the url
http://localhost:8080/alfresco/service/index/uri/slingshot/doclib/action/file/site/%7Bsite%7D/%7Bcontainer%7D which should show the service correctly added.
Step 8 - alter 'New Content' button action to invoke new serviceNow we have to use this new service we have created when we press the 'new content' button orbitz-toolbar.js onNewContent action line to read:
var actionUrl = YAHOO.lang.substitute(Alfresco.constants.PROXY_URI + "slingshot/doclib/action/file/site/{site}/{container}/{path}",
this will call our new slingshot service to create a file, which in turn will call the new remote api service we added to alfresco.
Step 9 - deploy and testNow, you should be able to press 'New Content' in share Document Library and create a new content item.
