FriendモデルのAASM対応とか、そんな感じ。
イヤ、なんか、もう、ね?
書くのが面倒になってきたwww
つうか、ね?
クリスマスを挟んで、FriendモデルをAASMに対応させて、「友達になろうぜ」メッセージを送れるようにして、受け取れるようにして、とかやってたんだけど、さ。
「おかしい。なんでstateが機能しないんだろう?」ってハマりにハマってたら、実は、Messageオブジェクトにstate付けようとしてました、とかwww
なんか、もう、ね?
あと、「ジョー・ブラックをよろしく」みたりとかwww
つうか、変わりすぎていて、ここに書くのも、もう、疲れたよパトラッシュ...
何だかとても眠いんだ...
とりあえず、AASMに関しては、毎度のごとく、ザリガニさんを参考に。
お世話になっております。
で、FriendモデルのAASM対応。
vendor/plugins/restful_authentication/lib/authorization/aasm_role.rbから、ごっそりコードを抜いて、以下のように書き換えて、friends_helper.rbとして、使っちゃいます。。
app/helpers/user/friends_helper.rb
module User::FriendsHelper module FriendsAasmRoles unless Object.constants.include? "STATEFUL_ROLES_CONSTANTS_DEFINED" STATEFUL_ROLES_CONSTANTS_DEFINED = true # sorry for the C idiom end def self.included( recipient ) recipient.extend( StatefulRolesClassMethods ) recipient.class_eval do include StatefulRolesInstanceMethods include AASM aasm_column :state aasm_initial_state :initial => :passive aasm_state :passive aasm_state :asked aasm_state :was_invited aasm_state :accepted, :enter => :do_make_friendship aasm_state :denied aasm_state :deleted, :enter => :do_delete_friendship aasm_event :ask do transitions :from => :passive, :to => :asked end aasm_event :be_invited do transitions :from => :asked, :to => :was_invited end aasm_event :accept do transitions :from => :was_invited, :to => :accepted end aasm_event :deny do transitions :from => :was_invited, :to => :denied end aasm_event :delete do transitions :from => [:accepted, :denied], :to => :delete end end end module StatefulRolesClassMethods end # class methods module StatefulRolesInstanceMethods # Returns true if the user has just been made friendship. def recently_made_friendship? @made_friendship end def do_delete_friendship self.deleted_at = Time.now.utc end def do_make_friendship @activated = true self.made_friendship_at = Time.now.utc self.deleted_at = nil end end # instance methods end end
んで、Friendモデル。
app/models/friend.rb
+ include User::FriendsHelper::FriendsAasmRoles + belongs_to :asked_to, :foreign_key => :was_invited_user_id, :class_name => "User" belongs_to :was_invited_from, :foreign_key => :asked_user_id, (略) def self.friendships(user) friends = user.asked_friends | user.was_invited_friends end + + def self.has_friendship?(user, friend) + friends = user.asked_friends | user.was_invited_friends + if friends.include?(friend) + friendship = Friend.find(:first, :conditions => { :asked_user_id => [user.id, friend.id], + :was_invited_user_id => [user.id, friend.id] + }) + return {:state => friendship.state, + :asked_user_id => friendship.asked_user_id, + :was_invited_user_id => friendship.was_invited_user_id + } + else + return false + end + end
has_friendship?メソッドを作ったよ。
誘った/誘われた実績がある場合、stateと誘ったヤツの:idと誘われたヤツの;idを返して、実績が無い場合は、falseを返す。
なんか、あんまり「?」じゃない気もするけど、まあ、ヨシとするwww
つうか、submitアクション、なんかコードひどいなwww
もうちょっと、完結に書けそうなのに、ね?
次は、user/friends_controller.rb。
app/controllers/user/friends_controller.rb
(略) + def add + @user = User.find(params[:id]) + if Friend.has_friendship?(current_user, @user) + flash[:notice] = "You are already have friendship with #{@user.nickname}" + redirect_back_or_default(user_profiles_path) + end end + def submit + @user = User.find(params[:id]) + friendship = Friend.has_friendship?(current_user, @user) + if friendship + case friendship[:state] + when "asked" + flash[:notice] = "訊いてる最中やん" + when "was_invited" + flash[:notice] = "訊かれてる最中やん" + when "accepted" + flash[:notice] = "もう友達やん" + when "denied" + flash[:notice] = "断られとるやん" + when "deleted" + flash[:notice] = "おらんようになっとるやん。" + end + else + @message = Message.new(params[:message]) + @message.message_type_id = MessageType.find_by_name(APP_CONFIG["message_type"]["be_friend"]).id + @message.sender_id = current_user.id + @message.reciever_id = params[:id] + @message.save if @message && @message.valid? + @friendship = Friend.new + @friendship.asked_user_id = current_user.id + @friendship.was_invited_user_id = params[:id] + @friendship.ask! + if @message && @message.valid? + flash[:notice] = "We are transmiting the message that you want to make friends with #{@user.nickname}" + end + end + if flash[:notice] + redirect_to(user_profiles_path) + else + flash[:notice] = "We couldn't send that message to #{@user.nickname}, sorry. Please try again, " + render(:action => "add") + end + end def destroy end
addアクションとsubmitアクションを作ったよ。
それぞれ、友達になろうぜメッセージの作成と、友達になろうぜメッセージの送信 with Friendオブジェクトのstateの設定。
んで、ルーティングの変更。
config/routes.rb
map.namespace :user do |user| user.resources :profiles - user.resources :friends + user.resources :friends, :member => { :add => :get, + :submit => :post + } end
あと、結構、スキーマ変更している。
migrateファイルを直接書き換えたりと醸してるんで、面倒だから、現状のスキーマ貼っとくwww
db/schema.rb
# This file is auto-generated from the current state of the database. Instead of editing this file, # please use the migrations feature of Active Record to incrementally modify your database, and # then regenerate this schema definition. # # Note that this schema.rb definition is the authoritative source for your database schema. If you need # to create the application database on another system, you should be using db:schema:load, not running # all the migrations from scratch. The latter is a flawed and unsustainable approach (the more migrations # you'll amass, the slower it'll run and the greater likelihood for issues). # # It's strongly recommended to check this file into your version control system.

つうか、ここに書いていることを読み返して、オレ、ちゃんともう一回作れるのかね?www
なんか、すんげえ欠落している気がするんですけどwwwwww
