Sharepoint托管的App 2013如何在自定义列表上启用评级

Question

Before i posted this question i have done some research to find the solution...with no luck

Here are some links to items i found

document rating in SharePoint 2013 hosted app

http://www.wictorwilen.se/Post/How-to-provision-SharePoint-2010-Rating-columns-in-Content-Types.aspx

The issue i have here is that i have a custom list that is part of the sharepoint app and need to add the sharepoint ratings system

When i add the columns as suggested in wictorwilen's to the list schema.xml, I get nothing more than a couple of number fields in the list.

How do i enable the "Ratings" feature in the app site collection and/or on the list instance?

this is the listInstance schema xml

Answer 1

Along the fields, the list root folder needs to have a property, "Ratings_VotingExperience" set to "Ratings" or "Likes". Here is the code using C# CSOM.

list.RootFolder.Properties["Ratings_VotingExperience"] = "Ratings";

Another option, would be to use CSOM entirely, without a custom Schema.xml. Here is a tested approach on enabling ratings on a list. You would have to convert the code from C# to Javascript, but this is trivial.

The basic steps are:

1. Add the Rating fields
2. Set the property on the root folder (Ratings/Likes)
3. Add the View fields for Ratings or Likes.
