Custom feed to only show articles from followed users - sql

Question

I have been referencing this rails tutorial to try to create a feed where only articles belonging to users who have accepted my friend requests appear in my feed.
However, i have a different schema and user model from the tutorial (i have an extra step where friend request is pending to be accepted). The below method in my user model does not filter out friendships which have not been accepted, hence articles of unconfirmed friends are appearing my feed, which is not what I want.
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
Pages controller
def home
#feed = current_user.feed.all
end
home.html.erb
<%= render #feed %>

Answer 1

for your case I think the key is here WHERE (user_id = :user_id AND accepted = true), I get accepted field from friendships schema.
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
