[Sqlalchemy-tickets] Issue #3567: BaseModel constructor is not documented (zzzeek/sqlalchemy)

[p-vital <iss...@bi...>]

New issue 3567: BaseModel constructor is not documented
https://bitbucket.org/zzzeek/sqlalchemy/issues/3567/basemodel-constructor-is-not-documented

p-vital:

https://pythonhosted.org/Flask-SQLAlchemy/api.html#flask.ext.sqlalchemy.BaseQuery has no documentation for BaseModel constructor. This:

- makes it unclear how to write BaseQuery derivative classes
- makes it unclear how to instantiate BaseQuery or derived class instances
