Creating an array of users from associations

srowsell — Fri, 17 Jan 2014 15:35:40 GMT

I have created a datalist (whose model is shown below, along with everything else) with two properties I need to turn into an array in a web script: recipientGroup and recipientUser. These are both multi-valued fields which are associations to groups and users, respectively.What I need to do with

If turning on the server-side JavaScript debugger by setting log4j.logger.org.alfresco.repo.web.scripts.AlfrescoRhinoScriptDebugger=on in log4j.properties is an option for you (e.g., you are running on your own local machine or you are running on a server with a GUI), you'll be able to inspect those two objects and figure out exactly why that comparison is returning false every time.

Jeff…

When I attempt to do this – I'm using a local instance (Enterprise 4.1.6) to develop here – I get the following exception on restart, and of course I can't log back in to Share. So for now I'll have to do without enhanced debugging.

Thanks,

Steve

I have done more investigating, and added the following snippet:


var addon=" ";
for (var i=0;i<200;i++)
{
   if ((items.assocs["reportdl:recipientUser"])!=null)
   {
      addon+=items.assocs["reportdl:recipientUser"][0]+" "+i+"    ";
   }
}

model.query=query+" "+userArray.length+" "+results.length+" ua "+userArray[0]+"   "+addon+"comparison: "+(userArray[0]==(items[127].assocs["reportdl:recipientUser"]));

‍‍‍‍‍‍‍‍‍‍‍‍‍

…which produces the following output (formatted for better readability) to the template:

It can be seen that value of userArray[0] looks from here like the same value as the association, but honestly this doesn't look like something I should be comparing at all. I should think that I would be able to compare a property of these associations (like a username or group name), but I have no idea what that would look like.

It is worth noting that the values of userArray all come from the values of items[].assocs["reportdl:recipientUser"), and for testing there's only one value (for multiple records of the datalist), so there is no way they should not agree (unless I'm comparing the wrong things, in which case I'm completely out to lunch anyway).

Speaking of lunch, there is a sandwich here that is whispering my name, and I must see what it wants.

I believe your problem is that you are using "==" to compare two objects. That only works when they are the same objects. In your case, even if those represent the same two *nodes* they are not the same *objects*.

Take a look at this:


var usr1 = people.getPerson('tuser1');
print(usr1.properties['cm:userName']);

var usr2 = people.getPerson('tuser1');
print(usr1.properties['cm:userName']);

if (usr1 == usr2) {
   print("Same");
} else {
   print("Different");
}

if (usr1.equals(usr2)) {
   print("Same");
} else {
   print("Different");
}

if (usr1.properties['cm:userName'].equals(usr2.properties['cm:userName'])) {
   print("Same");
} else {
   print("Different");
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

When run, the output is:


tuser1
tuser1
Different
Same
Same
‍‍‍‍‍‍‍

In this example I retrieve the same user into two different variables. Because those are different objects, an equals comparison is false. But if I use the equals method, or alternatively, compare to strings that will match, such as the user name, the comparison is true.

To find properties such as the user name or group name, use the node browser. Go to Company Home/System/People for people and Company Home/System/Authorities for groups. If you look at a group you'll see its name is cm:authorityName. For users it is cm:userName.

I used Florian Maul's <a href="http://share-extras.github.io/addons/js-console/">JavaScript Console</a> to run this little example. You should grab it if you don't have it.

Yeah, that's object-oriented programming 101. Something I should have picked up, but didn't, just because I wasn't really thinking of this thing as an object.

Thanks muchly for helping,
