flights relation (and model) missing

[matburnham]

Trying to extract flights for today causes an exception:

The above exception was the direct cause of the following exception:

So flights relation is missing. There's no flights.py in app/model. It looks like `flights2d.py' was removed in a18e6ae. I could try and re-create an appropriate table, but is this simply a file not committed to git?

Looks like something the following should work, based on INSERT INTO flights(date, sender_id, flight_type, multilinestring, simple_multilinestring)

from geoalchemy2.types import Geometry

from app import db

class Flight(db.Model):
    __tablename__ = "flights"

    date = db.Column(db.Date, primary_key=True)

    flight_type = db.Column(db.SmallInteger, primary_key=True)

    multilinestring = db.Column("multilinestring", Geometry("MULTILINESTRING", srid=4326))
    simple_multilinestring = db.Column("simple_multilinestring", Geometry("MULTILINESTRING", srid=4326))  # this is the path simplified with ST_Simplify(path, 0.0001)

    # Relations
    sender_id = db.Column(db.Integer, db.ForeignKey("senders.id", ondelete="CASCADE"), index=True)
    sender = db.relationship("Sender", foreign_keys=[sender_id], backref=db.backref("flights"))

    def __repr__(self):
        return "<Flight %s: %s,%s>" % (self.date, self.path_wkt, self.path_simple_wkt)


db.Index("ix_flights_date_sender_id", Flight.date, Flight.sender_id)
