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, primary_key=True) amount = db.Column(db.Integer) description = db.Column(db.String) paid = db.Column(db.Boolean, default=False)
Here is ModelView for Flask-Admin:
class OrderView(ModelView): column_filters = ("paid") admin.add_view(OrderView(Order, db.session))
Filters work fine, but I would like to make this filter default. Or better yet, do not use filters, and only show orders that are output of Order.query.filter(Order.paid==True) query.
Is it possible to do with Flask-Admin?
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.
