Question

This is a function to add a dictionary as a subitem of a main document.

addSubItem = function(id, data) {
  s = Item.findOne(id);
  if(s){
    Item.update({_id:id},{$push:{'subItemsList':data}});
  }
};

I verify the data passed and are a valid main document id a subitem data.

data = {num:1, value: 'Subitem1'};

This works fine yesterday with the latest version of meteor (0.4.2), but today I get this message at javascript console:

Error: Cannot apply $push modifier to non-array

I created and setup a new project and I still get the same.

Thanks to Lloyd, Nice workaround and thanks for the javascript crash course (i’m a begginer on it), but I found the solution: (note the “$push”)

addSubItem = function(id, data) {
  s = Item.findOne(id);
  if(s){
    Item.update({_id:id},{"$push":{'subItemsList':data}});
  }
};
