class Parent(db.Model):

admin.add_view(ModelView(Parent, db.session))
class Child(db.Model):

Hello -
The code above is an example of flask-admin page that I am trying to create. The goal is to have on Child's create page a text box for name and a drop down to select a parent.
With the above setup, there is only name field. The parent drop down box is missing.
Any ideas how to make it happen?
How about if you change the Child
class to this:
class Child(db.Model):
id = db.Column(db.Integer, primary_key = True)
name = db.Column(db.String(120))
parent_id = db.Column(db.Integer, db.ForeignKey('parent.id'))
parent = db.relationship('Parent', backref=db.backref('children', lazy='dynamic'))
I don't know much about this, and I don't know if you need the back reference, but this setup works for me with Flask-Admin.
