最適化したいコードがいくつかあります。まず、まったく悪くありませんが、主に update_result メソッドで、少し短くまたは速くなる可能性があります。
class Round < ActiveRecord::Base
belongs_to :match
has_and_belongs_to_many :banned_champions, :class_name => "Champion", :join_table => "banned_champions_rounds"
belongs_to :clan_blue, :class_name => "Clan", :foreign_key => "clan_blue_id"
belongs_to :clan_purple, :class_name => "Clan", :foreign_key => "clan_purple_id"
belongs_to :winner, :class_name => "Clan", :foreign_key => "winner_id"
after_save {self.update_result}
def update_result
match = self.match
if match.rounds.count > 0
clan1 = match.rounds.first.clan_blue
clan2 = match.rounds.first.clan_purple
results = {clan1=>0, clan2=>0}
for round in match.rounds
round.winner == clan1 ? results[clan1] += 1 : results[clan2] += 1
end
if results[clan1] > results[clan2] then
match.winner = clan1; match.looser = clan2
match.draw_1 = nil; match.draw_2 = nil
elsif results[clan1] < results[clan2] then
match.winner = clan2; match.looser = clan1
match.draw_1 = nil; match.draw_2 = nil
else
match.draw_1 = clan1; match.draw_2 = clan2
match.winner = nil; match.looser = nil
end
match.save
end
end
end
そして第二に、seeds.rb では完全に悪くて遅いです:
require 'faker'
champions = [{:name=>"Akali"},
{:name=>"Alistar"},
{:name=>"Amumu"},
{:name=>"Anivia"},
{:name=>"Annie"},
{:name=>"Galio"},
{:name=>"Tryndamere"},
{:name=>"Twisted Fate"},
{:name=>"Twitch"},
{:name=>"Udyr"},
{:name=>"Urgot"},
{:name=>"Veigar"}
]
Champion.create(champions)
10.times do |n|
name = Faker::Company.name
clan = Clan.create(:name=>name)
6.times do |n|
name = Faker::Internet.user_name
clan.players.create(:name=>name)
end
end
for clan in Clan.all do
2.times do
match = Match.create()
c = [clan,Clan.first(:offset => rand(Clan.count))]
3.times do
round = match.rounds.create
round.clan_blue = c[0]
round.clan_purple = c[1]
round.winner = c[0]
round.save!
end
for item in c
for p in item.players.limit(5)
rand_champion = Champion.first(:offset => rand(Champion.count))
match.participations.create!(:player => p, :champion => rand_champion)
end
end
match.save!
end
2.times do
match = Match.create()
c = [clan,Clan.first(:offset => rand(Clan.count))]
3.times do
round = match.rounds.create
round.clan_blue = c[0]
round.clan_purple = c[1]
round.winner = c[1]
round.save!
end
for item in c
for p in item.players.limit(5)
rand_champion = Champion.first(:offset => rand(Champion.count))
match.participations.create!(:player => p, :champion => rand_champion)
end
end
match.save!
end
2.times do
match = Match.create()
c = [clan,Clan.first(:offset => rand(Clan.count))]
2.times do |n|
round = match.rounds.create
round.clan_blue = c[0]
round.clan_purple = c[1]
round.winner = c[n]
round.save!
end
for item in c
for p in item.players.limit(5)
rand_champion = Champion.first(:offset => rand(Champion.count))
match.participations.create!(:player => p, :champion => rand_champion)
end
end
match.save!
end
end
それらを最適化するチャンスはありますか？
