I have enabled ratings on my list in sharepoint online using PnP script and the rating is now visible in the list but the ratings are not visible on the "View Item" form. I have used following code to enable rating on the List.
$Context = Get-PnPContext
$AverageRatingField = $Web.Fields.GetById([guid]"5a14d1ab-1513-48c7-97b3-657a5ba6c742") # AverageRating
$RatingCountField = $Web.Fields.GetById([guid]"b1996002-9167-45e5-a4df-b2c41c6723c7") # RatingCount
$RatedByField = $Web.Fields.GetById([guid]"4D64B067-08C3-43DC-A87B-8B8E01673313") # RatedBy
$RatingsField = $Web.Fields.GetById([guid]"434F51FB-FFD2-4A0E-A03B-CA3131AC67BA") # Ratings
$LikesCountField = $Web.Fields.GetById([guid]"6E4D832B-F610-41a8-B3E0-239608EFDA41") # LikesCount
$LikedByField = $Web.Fields.GetById([guid]"2CDCD5EB-846D-4f4d-9AAF-73E8E73C7312") # LikedBy
$Context.Load($AverageRatingField)
$Context.Load($RatingCountField)
$Context.Load($RatedByField)
$Context.Load($RatingsField)
$Context.Load($LikesCountField)
$Context.Load($LikedByField)
$Context.ExecuteQuery()
# Get the library for the site
$ServerRelativeUrl = $Web.ServerRelativeUrl
if ($ServerRelativeUrl -ne "/")
{
$ServerRelativeUrl = $ServerRelativeUrl + "/"
}
$List = Get-PnPList -Identity "MyList"
$ListRootFolder = $List.RootFolder
$ListRootFolderProperties = $ListRootFolder.Properties
$Context.Load($List)
$Context.Load($ListRootFolder)
$Context.Load($ListRootFolderProperties)
$Context.ExecuteQuery()
$List.Fields.Add($AverageRatingField)
$List.Fields.Add($RatingCountField)
$List.Fields.Add($RatedByField)
$List.Fields.Add($RatingsField)
$List.Fields.Add($LikesCountField)
$List.Fields.Add($LikedByField)
$List.Update()
$Context.ExecuteQuery()
# Update default view
$ListDefaltView = $List.DefaultView
$Context.Load($ListDefaltView)
$Context.ExecuteQuery()
$ListDefaltView.ViewFields.Add("Rating (0-5)")
$ListDefaltView.Update()
$Context.ExecuteQuery()
$ListRootFolderProperties["Ratings_x005f_VotingExperience"] = "Ratings"
$ListRootFolderProperties["Ratings_VotingExperience"] = "Ratings"
$ListRootFolder.Update()
$Context.ExecuteQuery()
