Are you asking when it’s appropriate to use it? As for how to use it, it’s pretty simple: http://docs.meteor.com/#/full/upsert
It’s used pretty much the same as update
but will insert if no matching document is found and the callback will return the _id
of the added document.
Ah, I should have started reading on update then. My first need was an upsert, so it never dawned on me to go to update. And I just now realized the dashed stuff to the right of “select” and “modifier” were actually links. I thought that was just some special markup for specific types.
OK, I still don’t get it.
I want to insert the following fields:
owner: Meteor.userId(),
firstName: firstName,
lastName: lastName,
address: address,
city: city,
state: state,
country: country,
addDate: new Date()
Unless the owner already has a record, in which I case I want to update these fields:
address: address,
city: city,
state: state,
country: country
so the selection is well documented … I can just do:
{ owner: Meteor.userId() },
but the modifier for this isn’t obvious. My best guess is:
{
firstName: firstName,
lastName: lastName,
address: address,
city: city,
state: state,
country: country,
addDate: new Date()
}
But I don’t want it to update addDate, firstName, lastName.
Ahhh, now it’s making sense.
