Flask-Admin default filters

Question

I would like to display only paid orders in my Flask-Admin model list view.

Here is models.py:

class Order(db.Model):
   id = db.Column(db.Integer, p

We do this in our app by overriding ModelView.

https://github.com/mrjoes/flask-admin/blob/master/flask_admin/contrib/sqla/view.py#L654

I looked through the source code a bit for Flask-Admin, and they've made the API easier to use since we last edited this code because it looks like you can just do:

from flask.ext.admin.contrib.sqla.view import ModelView, func

class PaidOrderView(ModelVew):
    def get_query(self):
      return self.session.query(self.model).filter(self.model.paid==True)

    def get_count_query(self):
      return self.session.query(func.count('*')).filter(self.model.paid==True)

(We were overriding get_list() which is not nearly as great.)

You can then use it like:

admin.add_view(PaidOrderView(Order, db.session))

Let me know if that doesn't work for you and I can take another look.
