Set default values in arrays

[Kefei Dan Zhou]

I have a structure that looks like this. How do I set default values
and required fields for 'data' field inside the list. I tried
'items.data' and '$items.data' but neither work.

structure = {
"items": [ {
"id": int,
"data": unicode,
} ],
}

You may try something like that:

default_values = { 'items': [{'id': 3, 'data':'foo'}] }

I'm having the same problem, and the solution on this thread doesn't
work for me.

Here's my code:

@con.register
class UserInfo(Document):
use_dot_notation = True
structure = {
'email_addresses': [{
'email': unicode,
'verified': bool,
}],
}
required_fields = []
default_values = {
'email_addresses': [{
'verified': True,
}],
}

It raises this exception when I instantiate a new document:

ValueError: Error in default_values: can't find email_addresses in
structure

I've also tried 'email_addresses.verified': False, in default_values.
That fails differently, when I call save(), with:

mongokit.schema_document.StructureError: missed fields : ['verified']

I'm using MongoKit 0.6, from PyPi.

How to specify the field "data" to be required?

structure = { 
     "items": [ { 
            "id": int, 
            "data": unicode, 
        } ], 
}

required_fields = ["items.data"] # This doesn't work.
