111 invalid type for key Pointer, expected *, but got string

Question

I am saving a object I call action to Parse.com

and I am getting the following error:

111 invalid type for key bookPointer, expected *Book, but got string

The code I use is:

 action.set("bookPointer", "SPecEgZUhL");

 action.save(null, {
                success: function (data) {
                    // The object was saved successfully.
                    callback(true);
                },
                error: function (data,error) {
                    // The save failed.
                    // error is a Parse.Error with an error code and description.
                    console.log("Error: " + error.code + " " + error.message);
                    callback(false);
                }
            });

And my Book data looks like:

How do I get the pointer to my book, my *book in javascript?

Make sense to me that it should work fine with the objectId.

Thanks!

Answer 1

A simpler/more strongly typed method would be:

// Assumes var Book = Parse.Object.extend("Book");
action.set("bookPointer", new Book({id: "SPecEgZUhL"}));

it's also not typically conventional to name columns after their type (eg "book" instead of "bookPointer")

Answer 2

As I said in the comment on the question, you can specify a pointer using a JS object like this in your case:

{
  __type: "Pointer",
  className: "Book",
  objectId: "SPecEgZUhL"
}

Final code becomes:

action.set("bookPointer", { __type: "Pointer", className: "Book", objectId: "SPecEgZUhL" });
