Sorting list of objects by object attribute? - ruby-on-rails

Question

I have a list of objects that are pulled in from an API. Here is the snippet of output (as there's about 300 lines):
combo =>
ID: 6, Name:Thomas Partey, Club:1, Position: 3, Price: $4.7, Total Pts: 57
ID: 7, Name:Martin Ødegaard, Club:1, Position: 3, Price: $7.0, Total Pts: 128
ID: 8, Name:Kieran Tierney, Club:1, Position: 2, Price: $4.6, Total Pts: 23
ID: 12, Name:Emile Smith Rowe, Club:1, Position: 3, Price: $5.6, Total Pts: 5
I would like to change the order so that they are ranked by Total Points rather than ID
I have tried the following:
sorted = combo.sort_by(#totalpoints)
As well as: (but I assume I want to try and use #teampoints since I've defined that)
sorted = combo.sort_by(:totalpoints)
My Full code is:
class Player
attr_accessor :id, :firstname, :secondname, :club, :position, :price, :totalpoints,
:active
def initialize(id, firstname, secondname, club, position, price, totalpoints, active)
#id = id.to_i
#firstname = firstname.to_s
#secondname = secondname.to_s
#club = club.to_s
#position = position.to_i
#price = price / 10.to_f
#totalpoints = totalpoints.to_i
#active = active.to_i
end
def to_s()
" ID: " + #id.to_s + ", Name:" + #firstname.to_s + " " + #secondname.to_s + ", Club:" + #club.to_s + ", Position: " + #position.to_s + ", Price: $" + #price.to_s + ", Total Pts: " + #totalpoints.to_s + " "
end
def self.pull()
require 'net/http'
require 'json'
url = 'https://fantasy.premierleague.com/api/bootstrap-static/'
uri = URI(url)
response = Net::HTTP.get(uri)
object = JSON.parse(response)
elements = object["elements"]
elements.map! { |qb|
if qb["chance_of_playing_next_round"].to_f > 0
Player.new(
qb["id"], # ID
qb["first_name"], # First Name
qb["second_name"], # Surname
qb["team"], # Club
qb["element_type"], # Position
qb["now_cost"], # Current Price
qb["total_points"], # Total Points
qb["chance_of_playing_next_round"]) # Chance Of Playing
end
}
end
combo = Player.pull().map{|qb| qb}
sorted = combo.sort_by(#totalpoints)
puts sorted
end

Based on what you've got shown, this should do what you need:
sorted = combo.sort_by(&:totalpoints)
It's essentially a shortened version of this:
sorted = combo.sort_by { |_combo| _combo.totalpoints }
