Implemented a unit test to check that tags are getting deleted when just their category gets deleted. See "cascade@category" in the result overview of the tests.
Added SQLAlchemy models for tag alias and implication relations.
Added test scripts to test basic tag functionalities. This does not include implication and alias which will have their own test scripts.
URL parameters are now URL decoded by the webservice
The tests now URL encode the parameters for every request.
Art2Presence relations are now creatable with POST requests to /artnet/metadata/art and listing the presences in the body.
Art2Presence tests have been introduced with relate_art.py
Also updated column name artist.description artist.name to fit a db schema update.
Added scripts to test various API calls of the webservice by creating, modifying and deleting entries from a test database of ArtNet. Do NOT use those on production.
