    <p>Hello I have some Problem with some foreign keys.</p> <p>I have something like this: </p> <pre><code>class Foo(db.Model): """The foo object.""" __tablename__ = 'foos_foo' id = db.Column(db.Integer, primary_key=True) title = db.Column(db.Text, unique=True) content = db.Column(db.Text) bar = db.relationship('Bar', backref='bars_bar') bar_id = db.Column(db.Integer, db.ForeignKey('bars_bar.id')) class Bar(db.Model): """The bar object.""" __tablename__ = 'bars_bar' id = db.Column(db.Integer, primary_key=True) name = db.Column(db.Text, unique=True) description = db.Column(db.Text) status = db.Column(db.SmallInteger, default=NEW) </code></pre> <p>I use this configuration style: <a href="https://github.com/mitsuhiko/flask/wiki/Large-app-how-to" rel="nofollow">https://github.com/mitsuhiko/flask/wiki/Large-app-how-to</a></p> <p>So I have something like this:</p> <pre><code>from app.foos.views import mod as foosModule from app.bars.views import mod as barsModule app.register_blueprint(foosModule) app.register_blueprint(barsModule) </code></pre> <p>If I call like in the config style from Mitsuhiko, python shell.py, comes this error:</p> <pre><code>sqlalchemy.exc.OperationalError: (OperationalError) no such table: bars_bar u'SELECT bars_bar.id AS bars_bar_id, bars_bar.name AS bars_bar_name, bars_bar.description AS bars_bar_description, bars_bar.status AS bars_bar_status \nFROM bars_bar' () </code></pre> <p>What goes on there? Yes the table is not there because I will create it? Is there a way to create some tables before some other? Or what do I wrong?</p> <p>Thanks for your time!</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
