Collection2 has no method 'callbacks'

[mfjohansson]

The code below gives me the following error message and a meteor chrash:

TypeError: Object [object Object] has no method 'callbacks'
    at app/lib/models.js:X:X

Issues = new Meteor.Collection2("issues", {
  schema: {
    title: {
      label: "Title",
      type: String
    }
  }
});

Issues.allow({
    insert: function() {
        return true;
    },
    update: function() {
        return true;
    },
    remove: function() {
        return true;
    },
    fetch: []
});


Issues.callbacks({
  insert: function(error, result) {
    if (error) {
      return console.log("Insert Error:", error);
    } else {
      alert("Inserted!");
      return console.log("Insert Result:", result);
    }
  },
  update: function(error) {
    if (error) {
      return console.log("Update Error:", error);
    } else {
      return alert("Updated!");
    }
  },
  remove: function(error) {
    return console.log("Remove Error:", error);
  }
});

Are you getting the error on the server? callbacks is only on the client, so that part of your code should only run on the client, whereas the rest of the code can and should be run on both. Wrapping that call in if (Meteor.isClient) { } will probably fix the error.

Also make sure that the collection2 package loads before autoform.

Thanks, it worked when I wrapped it with isClient since I had the code in my lib-folder.

Good. FYI, and for others who may look at this, I made a change so that there is no longer a server error. Callbacks are not used on the server, so in terms of having logical code organization, I would still recommend defining the callbacks in client code only, but it won't cause an error to put it in shared code going forward.
