Adding custom properties to system objects

[schipmolder]

Hi all,

Does anybody know if it's possible to add custom properties to system objects?
For example, if I'd like to add a property to a normal user, let's say a boolean 'receivedWelcomePack'?
Or to add properties to the existing st:site object (we're multi-tenant).

With repository objects we'd just add a custom model with a 'subclassed' object, e.g. my:file or my:folder, but I do not see how I can do this with objects that are created and managed by the system like users and sites.

Does anybody have any experience with this?

Thanks

Hello.

You can find a good sample on how to do what you want on this project https://github.com/sujaypillai/someco-people

Thanks Douglas, I see how you define the scp model with the shirt size property for scperson but what I don't understand is how this tells Alfresco to use scperson instead of cmerson objects.
If Alfresco still uses cmerson types surely it won't know about the shirt size property or am I missing something here?

Hello.
So, based on the project I shared with you, you don´t actually use scperson instead of cmerson.
If you check the xml model file carefully, you will see it's an aspect, and not a type.
In cases like this, you can write a behaviour to automaticaly attach the aspect to the person object, or you can create a folder rule and have it attaching the aspect for you.
By using aspects, you can add fields dinamicaly to any object.

Sorry for the late reply Douglas, the forum had been down for a while so i couldn't reply earlier.

I had not realised that these were aspects but that makes complete sense now, thanks a lot.

schipmolder _​ - When you say the forum was down, did you mean recently? We moved the forums a couple weeks ago, but this site shouldn't have had any issues! Can you let me know when you ran into trouble?

Hi Kirsten, Sorry, I meant during the migration that took a while.

I hadn't seen that the migration had completed until recently.

So, no it's not been down since the migration as far as I'm aware.

Whew. Just checking. Migration did take a good deal longer than we expected. Glad to see you in the new space!
