Counting created comments for all Posts

There's 1 comment for Post #2. When I try to create the first comment for Post #1, I get

/posts/1/comments/2

On comment's index page, it lists the same comments for all Posts, regardless of their ID.

comments_controller

def create
    @post = Post.find(params[:post_id])
    @comment = @post.comments.build(comment_params)
    @comment.user = current_user

    respond_to do |format|
      if @comment.save
        format.html { redirect_to [@post, @comment], notice: 'It was successfully created.' }
        format.json { render action: 'index', status: :created, location: @comment }
      else
        format.html { render action: 'new' }
        format.json { render json: @comment.errors, status: :unprocessable_entity }
      end
    end
  end

routes

resources :posts do
    resources :comments
end

On comment's index page, it lists the same comments for all Posts, regardless of their ID.

You must have defined CommentsController#index as below: def index @comments = Comment.all end which is why on comment's index page, you see same comments for all posts.

Assuming that you have nested routes as:

resources :posts do
  resources :comments
end

Update CommentsController#index as below:

def index
  @post = Post.find(params[:post_id])
  @comments = @post.comments
end

You should drop the database and recreate it again in order to start counting from the beginning.

rake db:drop
rake db:create

It is all about auto increment feature for keys (like :id) in databases.
