SQLite has no NOW()

[luckydonald]

As brought to my attention in pajowu@da292ad.

NOW() does not work in sqlite databases, which we use for local development. Since this field is not used elsewhere, I decided to simply remove it

pony_up/pony_up/version_db.py

Line 22 in eb8143c

upgraded = orm.Required(datetime, sql_default='NOW()')

• a) So maybe we should have a normal python default instead of the sql_default.
• b) It would make sense to allow users to provide their own version_db.register_database()
  

  pony_up/pony_up/version_db.py

  Lines 12 to 25 in eb8143c

  	def register_database(db):
  	"""
  	Applies the `Version` table to the given database.
  	:param db: the database
  	:type db: pony.orm.code.Database
  	:return:
  	"""
  	class Version(db.Entity):
  	version = orm.PrimaryKey(int, auto=False)
  	upgraded = orm.Required(datetime, sql_default='NOW()')
  	meta = orm.Optional(orm.Json, lazy=True)
  	# end class
  	# end def
