I have a simple model setup in my Ruby on Rails app. (User {name, username, lat, lon}) and am writing a basic extension to the model. I would like the method to return users within a certain distance. It all works just fine in the page view, but as I am debugging I would like to work through some testing using the script/console.
My question: It seems to be printing to the screen the entire result set when I run it from the command line and script/console.
My model:
class User < ActiveRecord::Base
def distance_from(aLat, aLon)
Math.sqrt((69.1*(aLat - self.lat))**2 + (49*(aLon - self.lon))**2 )
end
def distance_from_user(aUser)
distance_from(aUser.lat, aUser.lon)
end
def users_within(distance)
close_users = []
users = User.find(:all)
users.each do |u|
close_users << u if u.distance_from_user(self) < distance
end
return close_users
end
end
and from the command line I am running
>> u = User.find_by_username("someuser")
>> print u.users_within(1)
So, I guess I would like to know why it's printing the whole result set, and if there is a way to suppress it so as to only print what I want?
