Updating empty entry

[AStatkus]

Hello

I have issue updating empty entry, for example i create new empty entry:

db.insert({})

after it i would like to add some data:

db.update({'name':'test'}, doc_ids=[0])

I get KeyError, if i insert some value first it works fine.

Should it be so or i am not suppose to add empty entry?

Seems like you're trying to update a document with a document ID of 0. But inserting a document into an empty database will assign the document ID 1, not 0, as the return value of insert indicates:

>>> from tinydb import TinyDB, Query
>>> db = TinyDB('test.db')
>>> db.insert({})
1
>>> db.update({'name':'test'}, doc_ids=[1])
[1]
>>> db.all()
[{'name': 'test'}]
