How to run execute script as admin?

e-no91

I've created a javascript file :

var dest = companyhome.childByNamePath("Sites/test-script/documentLibrary/dari");
document.move(dest);
‍‍‍‍

The destination folder is where the user have no restriction.
I understand that I can use

<runas>admin</runas>
‍‍‍

in a workflow script, but how do I code this directly in the javascript file?

Thank you in advance!

To do this in javascript, you will have to write a custom javascript extension. Here is a link to a forum post which explains the steps to create a custom javascript extension.

You can take this steps as reference and create your own custom javascript extension in which write a method and set the authentication to run as admin/system user.

Hope this helps.

I thought it can be done simply through execute script.
Thank you for the link!

To answer your question for others that might come on this page like I did…

- The XML <runas>admin</runas> is for webscript in javascript. It's not usable when you are doing plain Javascript ( repo/data dicionnary/scripts ).

If you want to execute your Javascript method with admin rights, you will need to create an extension to the Javascript API. This API has been make in Java, so you will have to do some Java ( but not too much don't worry ). Note this extension is also called Javascript Root Object.

To deploy, you will have no other solution ( at the moment ) than doing an AMP file, which is the common way to deploy our stuff in Alfresco.

This has been tested on Alfresco 5.1 and should work on older version as well.
I will provide some links, for further information, but you should be able to achieve your goal without using them.

That said, let's go :

1) Create an AMP

To create an amp, you will have to use maven command.
This link will help you for further info : http://docs.alfresco.com/5.1/tasks/alfresco-sdk-tutorials-share-amp-archetype.html

Basically you use :

mvn archetype:generate -Dfilter=org.alfresco: 

Choose option 1

Use latest version, give your groupId… let's say we use here, com.example and artifactId runAsUtil

2) Update the source

Now we gonna inject some code in your AMP. So we will give a java file, and a context.

Here is the official and easier example if you want to go through it first [ up to you ] : http://docs.alfresco.com/5.1/references/dev-extension-points-javascript-root-objects.html

- Java :
File Name : RunAsAdminUtil.java
Location :

Create a folder Jscript ( you can change the name, but if you do, update all reference I will provide later ) as

<where_you_created_the_folder_with_maven>\runAsUtil\runAsUtil-repo-amp\src\main\java\com\example\jscript

Note that com\example might be different for you if you used a different groupId

Here is the full content of the Java file :

<java>
package com.example.jscript;

import org.alfresco.repo.jscript.BaseScopableProcessorExtension;
import org.alfresco.repo.security.authentication.AuthenticationUtil;
import org.mozilla.javascript.Function;
import org.mozilla.javascript.Context;
import org.mozilla.javascript.Scriptable;

public class RunAsAdminUtil extends BaseScopableProcessorExtension {

 public void runAsAdmin(final Function func, final Object args[]) {
 final Context cx = Context.getCurrentContext();
 final Scriptable scope = getScope();

 AuthenticationUtil.RunAsWork raw = new AuthenticationUtil.RunAsWork() {
 public Object doWork() throws Exception {
 func.call(cx, scope, scope, (args != null ? args : new Object[] {}));
 return null;
 }
 };
 AuthenticationUtil.runAs(raw, AuthenticationUtil.getSystemUserName());
 }

}
</java>

- Context file :
FileName : service-context.xml
Location : C:\Users\bertrand.barraud\Desktop\Alfresco TEST\runAsUtil\runAsUtil-repo-amp\src\main\amp\config\alfresco\module\runAsUtil-repo-amp\context

Note that runAsUtil is our artifactId

Content to add :

<xml>
&nbsp;&nbsp;&nbsp;<bean id="runAsUtil-repo-amp.customRootObject" 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; class="com.example.jscript.RunAsAdminUtil"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; parent="baseJavaScriptExtension">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<property name="extensionName" value="runAsUtil"/>
&nbsp;&nbsp;&nbsp;</bean>
</xml>

<beans>

&nbsp;&nbsp;&nbsp;<!– A simple class that is initialized by Spring –>
&nbsp;&nbsp;&nbsp; <bean id="custom-repo-amp.exampleBean" class="com.fiducial.demoamp.Demo" init-method="init" />

&nbsp;&nbsp;&nbsp; <!– A simple module component that will be executed once.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Note. this module component will only be executed once, and then there will be an entry for it in the Repo.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; So doing for example $ mvn clean install -Prun twice will only execute this component the first time.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; You need to remove /alf_data_dev for it to be executed again. –>

Note :
- value= is your artifactId
- id = [artifactId]-repo-amp.customRootObject
Ect..
Make sure your bean is well configurated. I advice to use the provided example before changing the naming

3) Compilation and Deployment

- Compilation :
Go to the root folder of the project ( folder generated by maven ) and use the command : mvn clean install -e

At this point if you have error, check all the steps and all your naming

- Deployment :
Get the amp file in <rootFolder>/runAsUtil-repo-amp/target should be named something like runAsUtil-repo-amp-1.0-SNAPSHOT.amp

Drop the file into your alfresco instance in the amp folder, should be located on your server somewhere like :
/opt/alfresco-one/amps ( on unix )

Apply the amp :
sudo sh /opt/alfresco-one/bin/apply_amps.sh

Note : You should see your amp in the list visible in the console

Restart alfresco :
sudo sh /opt/alfresco-one/alfresco.sh restart

—————-

You deployed the AMP ! Nice

Now you just need to know how to use this in your javascript !

4) Javascript

You just need to use the artifactId ( in your bean value= ) as the package/object name then the method you want to use. No import, no include nothing, it's directly usable from the API.

Example :
<javascript>
runAsUtil.runAsAdmin(moveDocument, [moveLocation]);
</javascript>
Note :
In this example, I give a parameter to my function. Do not forget the runAsAdmin method expect an array as second arg ! Else you will have an error, saying that the software can't find runAsAdmin.

Hope this help someone to not waste 2 days like I did

Good luck !!!
