Question

I have a set of models Day1, … ,Day7 .
How can I use an integer 1-7 to use the correct model?

class Day1 (db.Model):    #Monday
    courtday = db.ReferenceProperty(CourtDays)
    startTime = db.TimeProperty()
    endTime = db.TimeProperty()
    startTimeLunch = db.TimeProperty()
    endTimeLunch = db.TimeProperty()
    day = "Monday"

class Day2 (db.Model):    #Tuesday
    courtday = db.ReferenceProperty(CourtDays)
    startTime = db.TimeProperty()
    endTime = db.TimeProperty()
    startTimeLunch = db.TimeProperty()
    endTimeLunch = db.TimeProperty()
    day = "Tuesday"

Answer 1

You only need one model for a day, since they are all the same..

class Day (db.Model):
    courtday = db.ReferenceProperty(CourtDays)
    startTime = db.TimeProperty()
    endTime = db.TimeProperty()
    startTimeLunch = db.TimeProperty()
    endTimeLunch = db.TimeProperty()
    name = db.StringProperty()

days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
for dayname in days:
  newday = Day(name=dayname)
  newday.put()
