Do you mean that some properties of the content should be visible to some specific group only ?

Hi YogeshPj,
thanks for your reply. Yes, that is the goal of my request.

The metadata (properties) are displayed via forms. Forms can be assigned to view, edit and create modes. To control what people can see you will need custom form templates that display fields based on the calling users group(s). Not difficult but unfortunately you will need one form set per document type OR a pretty complicated ftl template.

You have to create different forms in share config file for each group.

I'm sorry, but I didn't understand how to assign a form at a group.

Can you show an example?

Thanks,

I'm not sure I agree with the need to create a form per group in share-config-custom because this is difficult to control and call (you need to make overrides to other bits of Alfresco), but you will need one template per document type or a very lengthy swicth statement as shown below.

Using Edit of a imaginary document type "mydoc:doc" which has only 2 properties (mydocrop1 and mydocrop2) as an example, I would do the following:-

Take a copy of the standard edit form template (share/WEB-INF/classes/alfresco/site-wescripts/org/alfresco/documentlibrary/forms)

Save it to your extensions directory and thenmodify the code at


            <div id="${formId}-fields" class="form-fields">
               <#list form.structure as item>
                  <#if item.kind == "set">
                     <@formLib.renderSet set=item />
                  <#else>
                     <@formLib.renderField field=form.fields[item.id] />
                  </#if>
               </#list>
            </div>
‍‍‍‍‍‍‍‍‍‍‍

to read something like


            <div id="${formId}-fields" class="form-fields">
               <#list form.structure as item>
                  <#if item.kind == "set">
                     <@formLib.renderSet set=item />
                  <#else>
                     <#assign showMe = true >
                     <#switch form.fields[item.id]>
                        <#case "mydoc:prop1">
                            <#assign showMe = false>
                            <#assign members = people.getMembers("prop1_group")>
                            <#list members as m>
                               <#if m.id == person.userid>
                                   <#assign showMe = true >
                                   <#break>
                               </#if>
                            </#list>
                            <#break>
                        <#case "mydoc:prop2">
                            <#assign showMe = false>
                            <#assign members = people.getMembers("prop2_group")>
                            <#list members as m>
                               <#if m.name == person.properties.userName>
                                   <#assign showMe = true >
                                   <#break>
                               </#if>
                            </#list>
                            <#break>
                     </#switch>
                     <#if showMe == true>
                          <@formLib.renderField field=form.fields[item.id] />
                     </#if>
                  </#if>
               </#list>
            </div>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then in share config custom tell the forms engine to use your template for this document type which you do by adding the line


            <edit-form template="../documentlibrary/forms/{your template name}"/>
‍‍‍

in the edit form definition after the field-visibility tags.

Re: See some properties only for a group

rosh — Thu, 05 Dec 2013 16:36:33 GMT

I tried with this code


<div class="form-field">
   <#if form.mode == "view">
      <div class="viewmode-field">
            <#assign members = people.getMembers(people.getGroup("site_cs-documenti_SiteManager"))>
            <#list members as m>
               <#if m.id == person.userid>
                 <span class="viewmode-label">${field.label?html}:</span>
         <span class="viewmode-value">${field.value?html}</span>
                 <#break>
                </#if>
            </#list>
   </#if>
</div>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But it return an error:
2013-12-05 17:38:52,140 ERROR [freemarker.runtime] [http-80-71] Template processing error: "Expression people is undefined on line 4, column 36 in org/alfresco/components/form/controls/cs-property-visibility.ftl."

This is odd because based on your error message people.getGroup() obvisously works, but people.getMembers() obviously does not. According to the Alfersco documentation both should work.

All I can suggest it confirm that people.getGroup() actually works as a stand alone and that people.getMembers doesn't. If that is the case then I can only suggest you raise another question on these forums for help, because at that stage your issue exceeds ny experience.

You could also try using people.getContainerGroups(). This works in Javascripts and will return a list of groups that the logged in user belongs to. You could then modfy the code I sent to check against the returned groups.

rosh — Fri, 06 Dec 2013 15:13:56 GMT

Hi,
I tried to use people.getGroup(), but it returned the same error.

For the moment, I will use this code:

 <#if user.lastName == "xxx"> ‍

However, I will try to resolve my problem.

Thanks for your replies.

I have done this one of the easiest way.

1. Set the groups in preferences in server side js.
2. Get the group in client side js(form.js file) and using DOM hide it.

Hi Govinda,
Could you give me a simple example?

Thanks

Re: See some properties only for a group

govinda — Mon, 09 Dec 2013 14:55:00 GMT

1> In preferance.get.js server side file, add the following code

var containerGroups = people.getContainerGroups(person),
            len = containerGroups.length,
            groups = [];
        if (len > 0) {
            for (var j = 0; j < len; j++) {
                var group = containerGroups[j].getQnamePath(),
                    p = group.split(":"),
                    gName = p[p.length - 1];
                logger.log("preferences group name = " + gName);
                groups.push(gName);
            }
        }
        preferences["groups"] = groups;

2> Check your group in form.js file and hide the required field

var pref = JSON.parse(Alfresco.constants.USERPREFERENCES);
if (pref.groups.indexOf("GROUP_ABC") != -1 ){
   Dom.get(this.parentId + "_prop_cm_name").parentNode.style.display = 'none';
}
