Dashlet Creation

[riktaminaars]

Hi

I have a folder where a new document is placed in every day, how can I automatically show this one most recent document in a dashlet ?

It only needs to show 1 document, so dashlets recent documents / my documents etc. not really useful. I tried creating my own dashlet myself but there is no tutorial around to learn this… The Hello-World dashlet on share-extras helped me understand the file&folder structure a bit more but I just can not find out how to display the most recent document from a simple folder

It sounds like you have seen how to create a dashlet, but maybe you are struggling with how to retrieve data from the repository from within your dashlet. Here is one way to do it.

Share tier web script controllers can make calls back to alfresco through the "remote" object. There may be out-of-the-box web scripts on the repository tier that would help you with this, but let's assume those don't meet your needs or that you just want/need to use your own. Given that, the high-level steps are:
1. Create a repository tier web script to query the repository to find the node you want and return metadata about that node as JSON.
2. Create a dashlet controller that uses the remote object to invoke the repository web script.
3. Place the object that is returned into the model and render the dashlet.

You've already seen the structure of dashlets and web scripts by working through the Hello World Dashlet in Share Extras. That's great. Let's build on that example and use that structure for this one.

Step 1: Build the repository tier web script

Create a new web script under config/alfresco/templates/webscripts/org/alfresco/example. Web scripts consist of a descriptor, a controller, and one or more views. Here are those files:

get-latest-doc.get.desc.xml

<webscript>
   <shortname>Retrieves Latest Document</shortname>
   <description>Returns properties of the latest document</description>
   <url>/example/get-latest-doc?nodeRef={nodeRef}</url>
   <format default="json">argument</format>
   <authentication>user</authentication>
   <transaction>none</transaction>
</webscript>‍‍‍‍‍‍‍‍

get-latest-doc.get.js

function main()
{
   parentNodeRef = search.findNode(args.nodeRef);
   var query = "PARENT:\"" + parentNodeRef.nodeRef + "\" AND TYPE:\"cm:content\"";
   var results = search.luceneSearch(query, "@cm:modified", false);
   model.latestDoc = results[0];
}
main();‍‍‍‍‍‍‍‍

The controller assumes it will be handed a node reference. It then does a search on that node reference, sorting the results by last modified date descending. That way, the latest document to be added to the folder is always the first search result. The result is added to the model so it can be rendered by the view.

get-latest-doc.get.json.ftl

<#macro dateFormat date>${date?string("dd MMM yyyy HH:mm:ss 'GMT'Z '('zzz')'")}</#macro>
<#escape x as jsonUtils.encodeJSONString(x)>
{
   "nodeRef": "${latestDoc.nodeRef}",
   "name": "${latestDoc.properties.name}",
   "title": "${latestDoc.properties.title}",
   "description": "${latestDoc.properties.description}",
   "created": "<@dateFormat latestDoc.properties.created />",
   "modified": "<@dateFormat latestDoc.properties.modified />"
}
</#escape>‍‍‍‍‍‍‍‍‍‍‍

This view is building a JSON object with selected metadata from the latest document.

That's it for the repository tier. Now let's create the dashlet.

Step 2: Create the dashlet

Dashlets are just web scripts. Under config/alfresco/site-webscripts/org/alfresco/components/dashlets, create the following files.

hello-latest-doc.get.desc.xml

<webscript>
   <shortname>Hello Latest Document</shortname>
   <description>Displays properties of the latest document to the user</description>
   <family>dashlet</family>
   <url>/components/dashlets/hello-latest-doc</url>
</webscript>‍‍‍‍‍‍

hello-latest-doc.get.js

function main()
{
    var json = remote.call("/example/get-latest-doc?nodeRef=workspace://SpacesStore/6fc1a5f9-31ac-4457-9620-eef4b82cabdd");
    if (json.status == 200)
    {
        obj = eval('(' + json + ')');
    }
    model.result = obj;
}
main();‍‍‍‍‍‍‍‍‍‍

This is the controller. It is using the remote object to call the web script you created in the prior step. Note the hard-coded node reference. That's the node reference to the folder you want to display in the dashlet. Obviously it would be better if you used dashlet configuration to let the user pick the folder. Regardless of how it is configured, you'll still end up passing a node reference to the repository tier web script.

hello-latest-doc.get.properties

header=Hello Latest Document!
label.hello=Hello Doc
label.name=Name
label.title=Title
label.description=Description
label.created=Created
label.modified=Modified‍‍‍‍‍‍‍

The config and the controller are done. The last step is to create the dashlet markup in the view.

Step 3: Create the dashlet's view

The view lives in the same folder as the rest of the web script. The file is named hello-latest-doc.get.html.ftl:

<script type="text/javascript">//<![CDATA[
   new Alfresco.widget.DashletResizer("${args.htmlid}", "${instance.object.id}");
//]]></script>
<div class="dashlet">
   <div class="title">${msg("header")}</div>
   <div class="body scrollableList" <#if args.height??>style="height: ${args.height}px;"</#if>>
     <div class="detail-list-item first-item last-item">
        <span>${msg("label.hello")}</span>
        <span>${msg("label.name")}</span>: <span>${result.name}</span><br />
        <span>${msg("label.title")}</span>: <span>${result.title}</span><br />
        <span>${msg("label.description")}</span>: <span>${result.description}</span><br />        
        <span>${msg("label.created")}</span>: <span>${result.created}</span>        <br />
        <span>${msg("label.modified")}</span>: <span>${result.modified}</span>        <br />
     </div>
   </div>
</div>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Deploy, Test, & Enjoy

If you put all of this in the Hello World Dashlet project, or used that as a starting point, all you should have to do is run ant to deploy this. I used hotcopy-tomcat-jar to stick the JAR in $TOMCAT_HOME/shared/lib. The JAR contains both repository tier and Share tier assets so if you were going to run those webapps on separate tiers, you'd have to either split your JAR or deploy it to both places. I actually prefer AMPs over JAR-based deployments and we believe AMPs to be the best practice, but for this little demo the JAR works nicely.

Summary

Dashlets on the Share tier need to communicate remotely to retrieve data from the repository tier. One way to do that is to create "data web scripts" on the repository tier that return JSON. That's what the get-latest-doc web script does. The dashlet on the Share tier (also a web script) makes a server-side call to the repository tier web script and grabs the JSON that is returned. The dashlet's view then arranges it as needed.

You'll want to add better config, error checking, comments, etc. But this should give you an idea of how it is done.

Fantastic!

I tried it out and it works great.. Really learned alot from this. Thank you!

Hi,
I've tried these steps. Please help me, I got an error related to the "TypeError: Cannot read property 'nodeRef' from null" and "result" variable.
Could you help me on this error :

aslon,

I have hardcoded the folder to use as a node reference in the controller. Based on the error message, I suspect that you either did not change the node reference, you used an invalid node reference, or you pointed to an empty folder.

Jeff

[aslon]

Thank you for the response, Jeff. Could you guide me step by step to do not use hard-code for "noderef"?
FYI, I've tried to use the "noderef" of my Company Home because I think all of my documents are on it. Unfortunately, I still get the same error, please help.

[jpotts]

Well, you could add a config XML for your web script and put the node ref in there. Of course that's just hard coding in a different place.

You could add a "configuration" link to the dashlet and persist the node ref to the dashlet config. I am working on that example but I may not have time to work on it this week. There are many dashlets out there that use a config in this way. Look at the RSS Feed, for example.

Also note that instead of using node ref you might want to use folder path.

I already extended the initial dashlet with configuration options like set the title for the dashlet and set a path for the folder to look for.

At this point you have to manually write the folder path (e.g. /Sites/sample-site/documentLibrary/…/) in the configuration of the dashlet, which works nicely but could easily be done by using the folder picker: http://i.imgur.com/hQGPL.jpg (image is from the javascript console).

That folder picker is using /share/res/modules/documentlibrary/global-folder.js so I figured I could re-use this but I'm still figuring out how to do this though, tips are welcome…

Code in next post…

Figured it out with the folder picker.. also added some basic validation. Now I'm trying to learn how to update/refresh the dashlet automatically after saving the configuration settings (now you'd have to refresh the whole page to see the changes). Pointers appreciated.
