Body
I have a strange error using Python 3.3.0 and SQLAlchemy 0.8.0: <pre><code>from sqlalchemy import create_engine, Integer, String, Text, Column, Sequence, DateTime, ForeignKey from sqlalchemy.orm import sessionmaker, relationship, backref from sqlalchemy.ext.declarative import declarative_base engine = create_engine("sqlite:///:memory:", echo=True) Session = sessionmaker(bind = engine) Base = declarative_base() class Product(Base): __tablename__ = "products" id = Column(Integer, primary_key=True) name = Column(String(200)) description = Column(Text) Base.metadata.create_all(engine) session = Session() product = Product() product.id = 1 product.name = "Test" product.description = "Test" session.add(product) print(product in session) # Expected true session.commit() print(session.query(Product).all()) # Expected the previous item </code></pre> As commented in code I expected the add method to add the product to the database using an INSERT. But it doesn't nor does it throw an exception. This is the log: <pre><code>2013-04-16 18:03:14,368 INFO sqlalchemy.engine.base.Engine PRAGMA table_info("products") 2013-04-16 18:03:14,369 INFO sqlalchemy.engine.base.Engine () 2013-04-16 18:03:14,371 INFO sqlalchemy.engine.base.Engine CREATE TABLE products ( id INTEGER NOT NULL, name VARCHAR(200), description TEXT, PRIMARY KEY (id) ) 2013-04-16 18:03:14,371 INFO sqlalchemy.engine.base.Engine () 2013-04-16 18:03:14,371 INFO sqlalchemy.engine.base.Engine COMMIT False 2013-04-16 18:04:04,706 INFO sqlalchemy.engine.base.Engine BEGIN (implicit) 2013-04-16 18:04:04,708 INFO sqlalchemy.engine.base.Engine SELECT products.id AS products_id, products.name AS products_name, products.description AS products_description FROM products 2013-04-16 18:04:04,709 INFO sqlalchemy.engine.base.Engine () [] </code></pre> I already tried several things: <ul> <li>Changing the engine doesn't work. I also tried postgresql. </li> <li>I tried debugging. When I reach the body of the add method there is nothing to step into.</li> </ul> Am I doing something wrong or is this a bug?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
