ModuleSource

Methods used for creating the SQLAlchemy extension in the compatible mode. The compatiblity is supported by the automatic falling-back strategy. For example,

  1. get_flask_sqlalchemy_lite(...) is a method returning the db extesnion of flask_sqlalchemy_lite.SQLAlchemy().
  2. If flask_sqlalchemy_lite is not installed but flask_sqlalchemy is installed, will return a db extension with a backend of flask_sqlalchemy.SQLAlchemy(). This wrapped extension will mimic the behaviors of flask_sqlalchemy_lite.SQLAlchemy().
  3. If both flask_sqlalchemy and flask_sqlalchemy_lite are not installed, raise a ModuleNotFoundError.
