自定義Feed只顯示關注用戶的文章

Question

我一直在參考this rails教程，試圖創建一個只有屬於已接受我的好友請求的用戶的文章出現在我的提要中的Feed。然而，我有一個不同的模式和用戶模型從教程（我有一個額外的步驟，朋友請求正在等待接受）。在我的用戶模型中的下面的方法不會過濾掉沒有被接受的友誼，因此未經證實的朋友的文章正在出現我的饋送，這不是我想要的。

user.rb

has_many :friendships 
    has_many :received_friendships, class_name: "Friendship", foreign_key: "friend_id" 
    has_many :active_friends, -> { where(friendships: { accepted: true}) }, through: :friendships, source: :friend 
    has_many :received_friends, -> { where(friendships: { accepted: true}) }, through: :received_friendships, source: :user 
    has_many :pending_friends, -> { where(friendships: { accepted: false}) }, through: :friendships, source: :friend 
    has_many :requested_friendships, -> { where(friendships: { accepted: false}) }, through: :received_friendships, source: :user 

    def feed 
    friend_ids = "SELECT friend_id FROM friendships 
        WHERE user_id = :user_id" 
    Article.where("user_id IN (#{friend_ids}) 
        OR user_id = :user_id", user_id: id) 
    end 

schema.rb

create_table "friendships", force: :cascade do |t| 
    t.integer "user_id" 
    t.integer "friend_id" 
    t.boolean "accepted", default: false 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

頁控制器

def home 
    @feed = current_user.feed.all 
end 

home.html.erb

<%= render @feed %>

對於你的情況，我認爲關鍵是這裏WHERE（USER_ID =：USER_ID並接受= TRUE），我得到接受了友誼架構字段。

def feed 
    friend_ids = "SELECT friend_id FROM friendships 
        WHERE (user_id = :user_id AND accepted = 't')" 
    Article.where("user_id IN (#{friend_ids}) 
        OR user_id = :user_id", user_id: id) 
    end
