has_many :through rails - ruby

Question

I want to get user1 to accept requests from other users to join user1s post as contributors and be listed out if user1 accepts them
Can't seem to get it to work - Here's my setup:
has_many :through
I'm thinking:
post model
class Post < ActiveRecord::Base
#Join table associations
has_many :group_requests, class_name: "Group",
foreign_key: "requester_id",
dependent: :destroy
has_many :group_users, class_name: "Group",
foreign_key: "accepted_id",
dependent: :destroy
has_many :requester, through: :group_requests
has_many :accepted, through: :group_users
def request(other_post)
group_requests.create(accepted_id: other_post.id)
end
# Unfollows a user.
def unrequest(other_post)
group_requests.find_by(accepted_id: other_post.id).destroy
end
# Returns true if the current user is following the other user.
def accepted?(other_post)
requesting.include?(other_post)
end
user model
class User < ActiveRecord::Base
#Join table associations
belongs_to :group
group model
class Group < ActiveRecord::Base
belongs_to :requester, class_name: "Post"
belongs_to :accepted, class_name: "Post"
validates :requester_id, presence: true
validates :accepted_id, presence: true
end
CreatePosts Migration
class CreatePosts < ActiveRecord::Migration
def change
create_table :posts do |t|
t.string :title
t.text :content
t.timestamps null: false
end
end
end
DeviseCreateUsers Migration
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.integer :post_id
t.string :email, null: false, default: ""
AddUserIdToPosts
class AddUserIdToPosts < ActiveRecord::Migration
def change
add_column :posts, :user_id, :integer
add_index :posts, :user_id
end
end
CreateGroup Migration
class CreateGroups < ActiveRecord::Migration
def change
create_table :groups do |t|
t.integer :requester_id
t.integer :accepted_id
t.timestamps null: false
end
add_index :groups, :requester_id
add_index :groups, :accepted_id
add_index :groups, [:requester_id, :accepted_id], unique: true
end
end
Post Controller
def accepted
#title = "Accepted"
#post = Post.find(params[:id])
#users = #user.accepted.paginate(page: params[:page])
render 'show_accepted'
end
def requester
#title = "Requesters"
#post = Post.find(params[:id])
#users = #user.requester.paginate(page: params[:page])
render 'show_requester'
end
private
def post_params
params.require(:post).permit(:title, :content, :image)
end
Post Show
<% #post ||= current_user(#post) %>
<div class="stats">
<a href="<%= accepted_post_path(#post) %>">
<strong id="following" class="stat">
<%= #post.accepted.count %>
</strong>
following
</a>
<a href="<%= requester_post_path(#post) %>">
<strong id="followers" class="stat">
<%= #post.requester.count %>
</strong>
followers
</a>
</div>
Any suggestions?

You could try this ---
as i think p is your post and you want to get all user_ids.
p.group_members.map{|gm|gm.user_id} #list of all ids in array
### OR try this
p.users #list of all users in array
#if you want to collect ids then
p.users.collect(&:id)
I think it should be helpful for you
