Need a cleaner way, which avoids too many 'if statements', to write this method for inputing data in
- by indiehacker
What is the best way to reference datastore model attributes without using the four 'if statements' I have in the below sample code, which seem messy and inefficient. For real-world code I may have a situation of 100 attributes such as self.var1, self.var2, ... self.varN that I want to some how reference with just an integer (or strings) as an argument to some method.
class PixelObject(db.Model):
zoom0 = db.ListProperty(int)
zoom1 = db.ListProperty(int)
zoom2 = db.ListProperty(int)
zoom3 = db.ListProperty(int)
zoom4 = db.ListProperty(int)
def inputZoomData(self, zoomInteger, input_data):
"""input_data goes to specified attribute based on if 0,1,2,3,or 4 is argument"""
if zoomInteger == 0: self.zoom0 = input_data
if zoomInteger == 1: self.zoom1 = input_data
if zoomInteger == 2: self.zoom2 = input_data
if zoomInteger == 3: self.zoom3 = input_data
if zoomInteger == 4: self.zoom4 = input_data
