so this is a function show() which I am trying to understand. in the model I do have a db.image table where I stored some images which is pointed in the function.
the only line I am not understanding here is
#image = db.image(request.args(0,cast=int))
In request.args(0, cast=int) why it has 0 as argument? and what does cast=int does? the complete function is below:
def show():
image = db.image(request.args(0,cast=int)) or redirect(URL('index'))
return dict(image=image)
