puzzlepiece.extras module
The extras module contains additional features that are useful, but not part of the
core puzzlepiece functionality. Currently this is just the datagrid - a Widget that
can be added to your Pieces, with multiple Piece-like Rows that use params for data storage
and manipulation.
The extras modules have to be imported explicitly:
# This will import the datagrid module:
from puzzlepiece.extras import datagrid
# The following will not work:
import puzzlepiece.extras as extras
extras.datagrid
