I have been given access to a database (MySQL, in case it matters) to access some data that I need, but I don't have direct access to the tables, the data is exposed through a SQL View. I want to wrap this in a small API using flask. For the database connection I intend to use SQLAlchemy (just because it's the only databse wrapper that I know in python). The thing is, I have read a lot of documentation, and dozens of stackoverflow posts and guides through the Internet, and I can't seem to find a way to query SQL Views from flask-SQLAlchemy. In the documentation, they always use Models. I tried to define my View as a Model, but I get could not assemble any primary key columns for mapped table 'MySQLView'. What I tried to do: class MyView(db.Model): __tablename__ = "my_view_name_in_sql" db.Column("id", db.Integer, primary_key=True) db.Column("sample_id", db.String) {...etc} Is there a way to do this, or maybe I should opt-out of using flask-SQLAlchemy and use something else instead?
