    def get_query(self):
        return super(ScreenAdmin, self).get_query().filter(Screen.number_of_pixels >= 100)

# Create admin
admin = admin.Admin(app, name='Example: SQLAlchemy2', template_mode='bootstrap3')
admin.add_view(ScreenAdmin(Screen, db.session))

Did you find a solution for this error? I run your code and facing with exact same problem, get_query function does not work properly. I open an question in StackOverflow, could you please help me if you find a solution for this.
