* Pass user to copy method on answer and doc ([`38941b0`](https://github.com/projectcaluma/caluma/commit/38941b0e6a336d2578b5786fd1c641565bd788a7))

Fix
* Don't use default on row_question if default table_answer exists ([`30ce974`](https://github.com/projectcaluma/caluma/commit/30ce974849b0a1d1d304e01d7158966a477bcb03))
* Fix setting default answers for sub forms ([`24d2899`](https://github.com/projectcaluma/caluma/commit/24d289941e464b90279042cbc73eb9fb897794b0))
* Use domain_logic for saving answers in form app ([`6b71559`](https://github.com/projectcaluma/caluma/commit/6b71559eb7a1dca280de625c89d7b4e65c02decc))

Fix

Fix
* Pass user instead of info object to data source ([`213d84a`](https://github.com/projectcaluma/caluma/commit/213d84ad6567405f77ae9392dba024a8d06767fa))

Breaking
* Pass the `user` to the `get_data` method of a data source instead of the whole `info` object since we don't have an info object when calling the python API. ([`213d84a`](https://github.com/projectcaluma/caluma/commit/213d84ad6567405f77ae9392dba024a8d06767fa))
