I'm treating a task hierarchy as a tree. I want to add a subtask to a
top-level task. But I don't want to append at the end of the existing
list, I want to put it at a specific position in the list.
Here's my existing record:
> db.master_projects.find()
{ "_id" : ObjectId("4ca1397c063911217433201c"), "children" : [
{
"title" : "Decide on process and resources"
},
{
"title" : "Make guardianship/trustee decisions"
},
{
"title" : "Make LivingWill decision"
}
], "priority" : 2, "reasoning" : "Why? Because I said so.", "title" :
"Make a Will for each Adult" }
Then I try to insert:
> var mp1 =
> db.master_projects.findOne({_id:ObjectId("4ca1397c063911217433201c")});
> mp1.children.insert(2, {title: 'Make asset dispersal decisions'})
Wed Sep 29 10:00:45 TypeError: mp1.children.insert is not a function
(shell):0
I'm sure this is easy, but I can't find an example online yet. (Book
is on order.)
