Using a webscript to display space content within web client

chrisb

We have been looking at some of the new for 2.1 webscript functionality.

I know its possible to use web scripts to generate a custom GUI for accessing the alfresco repository. Can webscript be used to render content for a space within the web client though?

For example can you use / call a webscript to display information in a space (similar to the way a freemarker template can currently be used to render space content in a custom format)?

If so how would you go about hooking using a webscript in a space for displaying content?

Thanks

By a happy coincidence that is exactly the feature I am working on right now. It will be available in 2.1 shortly. Depending on how much time there is available the feature may be "programmatic only" in other words there may not be any UI to select which webscript to execute, but it will be an easy matter of executing a very simple javascript to perform the setup of the webscript on a space. It will then appear as the Custom View for a space view.

Thanks,

Kevin

Excellent

. Look forward to trying that out.

Thanks

I have 2.1 installed on server but I guess I need a jumpstart on an actual example.

I see documentation in

http://wiki.alfresco.com/wiki/Web_Scripts

and I see the scripts mentioned in my installed version of alfresco..

What's missing is what example data and query would I need to enter in order to get back an actual result.

For instance when I execute /alfresco/service/sample/blog/category?c=web20&guest=true I get back

Failed to execute script 'workspace://SpacesStore//Company Home/Data Dictionary/Web Scripts/org/alfresco/sample/categorysearch.get.js': Node does not exist: workspace://SpacesStore//Company Home/Data Dictionary/Web Scripts/org/alfresco/sample/categorysearch.get.js ‍

That's a bug - thanks for spotting.

I have a fix which will be checked into HEAD tomorrow.

davidc

HEAD now contains the fix.

Also, http://wiki.alfresco.com/wiki/Web_Scripts_Examples has some examples.

1) Still getting same error on latest nightly
2) I am also unable to browse AVM repository with MySpaces webscript

davidc

Nightly build 401 should have the fix.

I'm not sure if the MySpaces portlet supports AVM.

garpinc

I went to http://dev.alfresco.com/downloads/nightly/dist/ and downloaded

alfresco-community-war-2.1.0dev.zip 19-Jun-2007 04:45 50M

If this is not the latest nightly then how can I get build 401

Also I check svn and I didn't see any changes which would lead me to this this was checked into head.

davidc

Ok, let me check.

davidc

I've just tested with the latest HEAD. The category sample is working, as well as the other two samples listed in http://wiki.alfresco.com/wiki/Web_Scripts_Examples

The code fix for

Failed to execute script 'workspace://SpacesStore//Company Home/Data Dictionary/Web Scripts/org/alfresco/sample/categorysearch.get.js': Node does not exist: workspace://SpacesStore//Company Home/Data Dictionary/Web Scripts/org/alfresco/sample/categorysearch.get.js‍

is in org.alfresco.web.scripts.ScriptProcessor - line 108 - it should read:

        return scriptService.executeScript("javascript", location, model);        ‍

before it was:

        return scriptService.executeScript(location, model);        ‍

garpinc

Testing with head works… I just did full compile.. This indicates to me that nightly build is broken because it does not work.

Also on testing folder sample I attempted to browse AVM content. It still looks like this is not possible because I'm getting a NullPointerException

java.lang.NullPointerException  
    
 org.alfresco.web.scripts.bean.ContentGet.execute(ContentGet.java:141)

 org.alfresco.web.scripts.WebScriptRuntime$1.execute(WebScriptRuntime.java:159)  ‍‍‍‍‍‍

1) What is the recomended way to browse AVM content using webscripts? Please provide example if you have one.

2) If this feature is not available yet when will it be available?

kevinr

The MySpaces portlet cannot browse AVM spaces.

The AVM API is supported for Template and Script engines in 2.1.

Here is an example of AVM template API usage that displays meta-data about an AVM store (specified as the 'store' argument to the template) and recursively lists the contents of the store in a table. It could easily be converted to a webscript:

<#assign mystore=avm.lookupStore(args["store"])>
<#if mystore?exists>
   Found store: ${mystore.name}
   <p>
   Store root node name: ${avm.lookupStoreRoot(args["store"]).name}
   <p>
   Store root node detail:<br> 
    Info: ${mystore.lookupRoot}<br>
    Name: ${mystore.name}<br>
    Creator: ${mystore.creator}<br>
    Created Date: ${mystore.createdDate?datetime}
   <p>
   Store contents:<br>
   <table>
      <tr><th></th><th>Name</th><th>Path</th><th>Type</th><th>Parent</th><th>Created</th><th>Modified</th></tr>
      <@dir node=mystore.lookupRoot depth=0/>
   </table>
<#else>
   CANNOT FIND STORE: ${args["store"]}
</#if>

<#macro dir node depth>
   <#list node.children as c>
      <tr>
         <td width=16>
            <#if c.isDocument>
               <a href="${url.context}${c.url}" target="new"><img src="${url.context}${c.icon16}" alt="${c.name}" title="${c.name}" border=0></a>
            <#else>
               <img src="${url.context}${c.icon16}" alt="${c.name}" title="${c.name}" border=0>
            </#if>
         </td>
         <td>
            <font size='${4 - depth}'>${c.name}</div>
         </td>
         <td>
            ${c.path}
         </td>
         <td>
            ${c.type}
         </td>
         <td>
            ${c.properties.created?datetime}
         </td>
         <td>
            ${c.properties.modified?datetime}
         </td>
      </tr>
      <#if c.isContainer && c.children?size != 0>
         <@dir node=c depth=depth+1/>
      </#if>
   </#list>
</#macro>
