rails structuring routes/controller/views for nested resources

问题

I have rails app with the following structure:

user has_many posts post has_many post_comments post_comment has_many comment_replies

I'm planning to use the following routes to avoid deep nesting.

resources :posts do
  resources :post_comments, module: :posts
end

resources :comments do 
  resources :comment_replies, module: :post_comments #is this module a good choice?
end

This gives the following controller structure

post_comments      GET    /posts/:post_id/comments(.:format)  posts/comments#index
                   POST   /posts/:post_id/comments(.:format)                       posts/comments#create
new_post_comment   GET    /posts/:post_id/comments/new(.:format)                   posts/comments#new
 edit_post_comment GET    /posts/:post_id/comments/:id/edit(.:format)              posts/comments#edit
      post_comment GET    /posts/:post_id/comments/:id(.:format)                   posts/comments#show
                   PATCH  /posts/:post_id/comments/:id(.:format)                   posts/comments#update
                   PUT    /posts/:post_id/comments/:id(.:format)                   posts/comments#update
                   DELETE /posts/:post_id/comments/:id(.:format)                   posts/comments#destroy


comment_repiles     GET    /comments/:comment_id/repiles(.:format)                  comments/repiles#index
                    POST   /comments/:comment_id/repiles(.:format)                  comments/repiles#create
 new_comment_repile GET    /comments/:comment_id/repiles/new(.:format)              comments/repiles#new
edit_comment_repile GET    /comments/:comment_id/repiles/:id/edit(.:format)         comments/repiles#edit
     comment_repile GET    /comments/:comment_id/repiles/:id(.:format)              comments/repiles#show
                    PATCH  /comments/:comment_id/repiles/:id(.:format)              comments/repiles#update
                    PUT    /comments/:comment_id/repiles/:id(.:format)              comments/repiles#update
                    DELETE /comments/:comment_id/repiles/:id(.:format)              comments/repiles#destroy

My problem is with sturcturing the folders.

For controllers: It means I put the posts_controller in the main folder and the post_comments_controller goes into posts folder. Until now it's clear. But for comment_replies I should put it in the comment_replies folder which is totally separated from where post_comments_controller can be found.

For views: I have a create.js.erb for posts in the 'post' folder. I have a create.js.erb for post_comment in the posts/post_comments folder. According to my routes I should put the create.js.erb for comment_replies into the post_comments/comment_replies folder. But this seems to be counterintuitive again just like the controller example.

What is the rails convention/ common solution in this case? Btw. I don't wanna show comments or replies separately from their post.

UPDATE

posts_controller

def index
  ....
  @post_comments = @post.post_comments #showing all comments
  @post_comment = PostComment.new #new comment via js
  respond_to do |format|
    format.js
  end
end

post_comments controller

def create
  @post = Post.find(params[:id])
  @post_comment = @post.post_comments.build(post_comment_params)
  @post_comment.save!
end
