Form control for multiple association on aspect reference

Jump to solution

Hi i need to emulate the dialog show from the action "manage-aspects" , on a field form control on Alfresco Share.

My point is to make the user select a list of aspect and send that list to the java backend service code with the post of the from and in that moment i use the aspects selected from the user for making things on the java code.

I have tried to emulate the  Multiple association with person nodes

(you can find a example on this project GitHub - angelborroy/alfresco-controls: Samples for Alfresco Share controls )

This is a simple model:

<?xml version="1.0" encoding="UTF-8"?>
<model name="up:testModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

    <description>eeeee</description>
    <author>eeeeeeeeeeeeee</author>
    <published>eeeeeeeeee</published>
    <version>1.0</version>

    <imports>
         <!-- Import Alfresco Dictionary Definitions -->
         <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d"/>
         <!-- Import Alfresco Content Domain Model Definitions -->
         <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm"/>
         <!-- Import Alfresco Data List Model Definitions -->
         <import uri="http://www.alfresco.org/model/datalist/1.0" prefix="dl"/>
    </imports>

    <namespaces>
        <namespace uri="extension" prefix="up"/>
    </namespaces>
    
    <aspects>
        <aspect name="up:test">
            <title>Test</title>
            <properties>
                <property name="up:testMultipleText">
                  <title>testMultipleText</title>
                  <type>d:text</type>
                  <multiple>true</multiple>
                  <index enabled="true">
                    <atomic>true</atomic>
                    <stored>false</stored>
                    <tokenised>false</tokenised>
                  </index>
                </property>
             </properties>
            <associations>
                <association name="up:testMultipleAssociation">
                    <title>testMultipleAssociation</title>
                    <source>
                        <mandatory>false</mandatory>
                        <many>true</many>
                    </source>
                    <target>
                        <class>cm:content</class>
                        <mandatory>false</mandatory>
                        <many>true</many>
                    </target>
                </association>
            </associations>
            <overrides></overrides>
            <mandatory-aspects></mandatory-aspects>
        </aspect>
    </aspects>

</model>

I need to save  a list of name of the aspects or a list of associations to the aspects on the post of the form.

Anyone have already done this?

Greetings.

Hello,

You can not associate aspects with documents using an association in the model.

The simplest and quickest way but of course not the best is using the param option of selectmany control with a text or multitext property:

<field id="up:testMultipleText">
<control template="/org/alfresco/components/form/controls/selectmany.ftl">
<control-param name="options">up:aspect|Aspect,up:aspect2|Aspect2,up:aspect3|Aspect3</control-param>
</control>
</field>
‍‍‍‍‍‍‍‍‍

However, the correct way will be indeed develope a custom control based on selectmany but obtaining the options using an Ajax call to the repository.

Regards.

Why you would like to save the list off association/aspect in the node/document.Aspects associated with document can also be retrieved in java using some java services like nodeservice.

If you would like to perform some operation when particular aspect is added in document, this is also possible using policies and behavior.You can get more details on that on below link.

Hi Krutik,

in my use case it's more a "Client Share" solution than a "Alfresco Server" solution (like the behaviours).

I just want to know if anyone (before i started to developed) have already done a specialized FTL like the standard "selectmany.ftl" control  form field for select the aspects and send in to the FormData to alfresco.

I need to force my user to create content with some aspects but i can't use the behaviour because i can't predict what aspects the users want to use so i let them choose from a list in a page form dialog on Share.

Greetings.

k the more simple solution i found is like Roberto tell, i ctumozie a sleect-many template .

Here the my ftl for anyone can found useful:

<#include "/org/alfresco/components/form/controls/common/utils.inc.ftl" />

<#if field.control.params.size??><#assign size=field.control.params.size><#else><#assign size=5></#if>

<#if field.control.params.optionSeparator??>
   <#assign optionSeparator=field.control.params.optionSeparator>
<#else>
   <#assign optionSeparator=",">
</#if>
<#if field.control.params.labelSeparator??>
   <#assign labelSeparator=field.control.params.labelSeparator>
<#else>
   <#assign labelSeparator="|">
</#if>

<#assign fieldValue=field.value>

<#if fieldValue?string == "" && field.control.params.defaultValueContextProperty??>
   <#if context.properties[field.control.params.defaultValueContextProperty]??>
      <#assign fieldValue = context.properties[field.control.params.defaultValueContextProperty]>
   <#elseif args[field.control.params.defaultValueContextProperty]??>
      <#assign fieldValue = args[field.control.params.defaultValueContextProperty]>
   </#if>
</#if>

<#if fieldValue?string != "">
   <#assign values=fieldValue?split(",")>
<#else>
   <#assign values=[]>
</#if>

<div class="form-field">
   <#if form.mode == "view">
      <div class="viewmode-field">
         <#if field.mandatory && !(fieldValue?is_number) && fieldValue?string == "">
            <span class="incomplete-warning"><img src="${url.context}/res/components/form/images/warning-16.png" title="${msg("form.field.incomplete")}" /><span>
         </#if>
         <span class="viewmode-label">${field.label?html}:</span>
         <#if fieldValue?string == "">
            <#assign valueToShow=msg("form.control.novalue")>
         <#else>
            <#if field.control.params.options?? && field.control.params.options != "" &&
                 field.control.params.options?index_of(labelSeparator) != -1>
                 <#assign valueToShow="">
                 <#assign firstLabel=true>
                 <#list field.control.params.options?split(optionSeparator) as nameValue>
                    <#assign choice=nameValue?split(labelSeparator)>
                    <#if isSelected(choice[0])>
                       <#if !firstLabel>
                          <#assign valueToShow=valueToShow+",">
                       <#else>
                          <#assign firstLabel=false>
                       </#if>
                       <#assign valueToShow=valueToShow+choice[1]>
                    </#if>
                 </#list>
            <#else>
               <#assign valueToShow=fieldValue>
            </#if>
         </#if>
