3 Easy Steps: Applying Permissions Using Alfresco Web Client

July 28, 2011 1 comment


In Alfresco, you apply permissions to certain space/folder or documents to restrict  a user to certain actions that he/she can perform on a folder or document. For example, you don’t want everyone to to have a capability to create documents or folders in Folder A. What you can do is to apply a READ ONLY permission to a user to  Folder A. In this way, a user can only VIEW the contents of Folder A.

For beginners, below  are the steps  to apply permission using Alfresco  web client:

1. Log in to Alfresco and proceed to the space/folder you want permissions to be applied. Click More Actions –> Manage Space Users.

2. Click  Invite. You’ll proceed to Invite Users Wizard page. In this page, you can invite a user or a group by selecting from the drop down list of Specify Users/Groups. Enter a group name or username and then click the search button. Select a user or group from the search result and then select a Role you want a user to have as seen below:

Note: To further understand what Roles are, you can visit this link.

3. Click Add to List button. Click Next. You will be directed to a page which will ask you if you want to send an email to the invited user, for  now select No and click Finish button and you’re done! You should be able to see that the user has now a Role in the specified folder.

Now we are done! Please note that applied permissions will only affect the space to which it is applied. You can also apply permission using java-script API’s provided by Alfresco. On my next post, I will concentrate on using java-script to apply permissions. =P


5 Easy Steps To Get All Root Groups in Alfresco Using Web Scripts

Get All Root Groups in Alfresco

I was too curious and wonder how I can get or visibly see all the groups in Alfresco aside from using the Admin Console functionality.  I found out that it is possible using web scripts.

The Problem

I want to display in a web browser the list of all groups in Alfresco using a simple java-script web script.

The Solution

NOTE: I will assume you know how to create a web script, or at least have an idea. =P

1. Log in to your Alfresco as admin.

2. Locate ‘Web Scripts Extensions‘ folder (Company Home > Data Dictionary > Web Scripts Extensions)

Figure 1: Web Scripts Extensions Page

This folder is where we usually put our custom web scripts. By default, custom web scripts should be pit in this folder.

3. Create a folder (any name will do, e.g. getAllGroups) inside the Web Scripts Extensions folder.

4. Under the folder created in step 3, we create the 3 files below:

a. getAllGroups.get.desc.xml – the descriptor file that is responsible for registering our web script in Alfresco. This file will containt the following code

    <shortname>Gets All the Groups  in Alfresco</shortname>
    <description>This  is a sample web script</description>
    <format default=”html”/>

The explanation for each tags can be found here.

b. getAllGroups.get.html.ftl – free-marker template, used to represent the response data from Alfresco. Below is an example with formatting.

               <th>Short Name</th>
               <th>Full Name</th>
               <th>Display Name</th>
       <#list alfrescoGroups as g>

c. getAllGroups.get.js – this is where the logic of the code is located. Alfresco exposed some javascript  API’s which developers can use to access Alfresco repository. For groups and authority related API, we will use the Groups (Authority Service). Below is a sample code using groups API:

/*@author – anythingalfresco: Gets all the root groups in Alfresco*/

//javascript API that gets all the root groups in Alfresco
var myGroups = groups.getAllRootGroups();

model.alfrescoGroups = myGroups;

5. After creating these 3 files, go to the web scripts index page at http://localhost:8080/alfresco/service/index and click Refresh Web Scripts button. Invoke the web script uri (http://localhost:8080/alfresco/service/get/all/groups) and the result should be like the one below:

Figure 2: Sample Result

Now we are done! It’s quite easy? You can try the code in your Alfresco installation and see if it works. BTW, I’ve used Alfresco Enterprise 3.2r in this example. But, it should work in higher versions too. If you want to know more about about Alfresco web scripts, you can visit the Alfresco wiki. =P
