Question

In 1.7 release NDB got support projection queries, documentation states that this is the syntax:

qry = Article.query(projection=[Article.author, Article.tags])

But running this results in the exception:

TypeError: __init__() got an unexpected keyword argument 'projection'

So is there a support for projection queries in the NDB, if yes how to use it?

Answer 1

There is an error in the documentation, the correct syntax is:

qry = Article.query().get(projection=[Article.author, Article.tags])

…replace get with method of your choosing as long as it takes **q_options arguments.
