does anybody know whether it is possible to add new rating entries to Knowledge articles with Apex code?
If yes, how would that code look like?
I found some information on how to read the KnowledgeArticleVoteStat object for a given KB article with SOQL, which has the NormalizedScore attribute available.
But I am not sure, how to work with that information.
Would appreciate any help.
Thanks!
The knowledge article data model is polymorphic in nature.
Hence the creation of the knowledge article process is similar to creation of any other record except we have articletype appended by __kav to get the object name.
Hence to create initial version via API i would use the same calls as I use for other objects.
You will have to insert a knowledge article using the API as below:
curl https://na1.salesforce.com/services/data/v20.0/sobjects/FAQ__kav/ \
-H "Authorization: Bearer token \
-H "Content-Type: application/json" \
-d @newaccount.json"
# newaccount.json:
{
"summary" : "Express Logistics and Transport"
//Include various fields here
}
Remember to set up REST API you will first have to OAUTH with salesforce or obtain session ID using login() call
Also once you draft an article you can manage its lifecycle through various API documented in chapter four of the guide.
Yes, is possible if you create a visualforce page for displaying the articles, then you could store the result of that action on a 'feedback' object.
To add a change the 'template' behind an article, go to the article type you wish to modify and select the visualforce page you have created (see Screenshot).
To be able to select the page, the page needs to use the current article type as standard controller.

If you have a look at the entity relationship diagram (ERD) which illustrates relationships between the Salesforce Knowledge objects, you will see that the Vote object is related with the KnowledgeArticle. So to create a rating with Apex, you will simply have to create a new record of VOTE sObject and set the parentId as the KnowledgeArticleId and the Type as the rating score i.e. 1,2,3,4 or 5.
One important thing that you need to keep in mind while creating votes through APEX is that each user can rate an article only once. If you attempt to rate the same article again by the same user then an exception would be thrown as APEX would not allow duplicate vote entries by the same user for the same article
