Protect spaces

jumpm7 — Mon, 25 May 2009 11:37:55 GMT

Hallo,do you know how to protec spaces from cut or delete command? In my example I have some spaces were users work, implementing a kind of workflow. Therfore the users must have the write permission inside the spaces. The problems cames when a user makes an error and cut (or delete) an entire space

Here is what I would do :

- create a custom aspect :


<aspect name="custom:protectedFolder">
        <title>Espaces proteges de copier et couper</title>
</aspect>
‍‍‍‍‍

- then, edit your web-client-config-custom.xml :


 <config evaluator="aspect-name" condition="custom:protectedFolder">
      <actions>
    <!– Actions Menu for More Actions in Browse screen –>
         <action-group id="browse_actions_menu" replace="true">
            <action idref="cut_node" hide="true"/>
            <action idref="copy_node" hide="true"/>
         </action-group>
<action-group id="space_browse">
             <action idref="cut_node" hide="true"/>
            <action idref="copy_node" hide="true" />
         </action-group>
<action-group id="space_details_actions">
              <action idref="cut_node" hide="true"/>
            <action idref="copy_node" hide="true" />
         </action-group>
   </actions>
</config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then, each space having this aspect won't display the "cut" and "copy" actions…

But, no user (even admin) will see these buttons

The proposed solution is quick but what is doing is just hiding the delete, cut & co. from the web client. It is no t really protectintg against deleting or cuttng (which can be done using by program or using another interface like FTP, CIFS, WebDAV).

To make it really safe, you have to do it in the repository defining your type and associated permissions. Not easy since as you say, you need write permission for those spaces.

You can just use custom behaviour to deal with deletes for the folders with the aspect.

Brilliant! I mean, even if it is not a "full" protection it is engouth strong because the main problem is the user interaction via web. Other interactions ( ftp for example ) are made by automatic scripts that are tested.
I'm going to introduce your suggestions on our system

Thanks a lot

No problem.

Good luck

Are you sure of that ?

As mentioned above, custom behaviours can be associated to custom types for several events. The behaviour code that is then triggered can be written in java o javascript. This code can do whatever do you want it to do with the permissions of a node.

I'having a little trouble due to my poor experience in Alfresco.

What I did is:

1. In "customModel.xml" added the code about the aspect name and title
2. Renamed custom-model-contex.xml.sample in custom.model-contex.xml
3. In "web-client-config-custom.xml" added the code about aspect definition (config evaluator….etc. )
4. Restart alfresco

I have no errors in logs, but when I create a new business rule, selecting "add aspect to item" , I cannot see the new custom aspect. I tried to activate some more debug info without any useful info.
I reviewed the procedure looking at Munwar Shariff's book and I cannot find what is wrong…

If you want include custom behaviour, look for J. Potts tutorial at:

http://www.ecmarchitect.com
http://ecmarchitect.com/alfresco-developer-series
http://ecmarchitect.com/images/articles/alfresco-behavior/behavior-article.pdf

this is the ultimate reference on how to do it.

Re: Protect spaces

You have to add the following to tyhe web-client-config-custom.xml :


<config evaluator="string-compare" condition="Action Wizards">
      <aspects>
         <aspect name="custom:protectedFolder"/>
      </aspects>
   </config>
‍‍‍‍‍‍‍

This will tell Alfresco that you want this aspect to appear in the "add aspect to item" action dialog

Many thanks

where can you see the "cut" icon ?

Re: Protect spaces

jumpm7 — Fri, 29 May 2009 08:05:11 GMT

The icon is visible both near the objct name and in the "more actions" menu

Re: Protect spaces

jayjayecl — Fri, 29 May 2009 09:01:53 GMT

Strange.

Try


 <config evaluator="aspect-name" condition="custom:protectedFolder" replace="true">
…
‍‍‍‍

instead of


 <config evaluator="aspect-name" condition="custom:protectedFolder" >
…
‍‍‍‍
