rails redirect from child create to child show

Question

I am sure there is a solution for this but I am not seeing it. I want to redirect to the show page for my child after creation.

I have just created a child record for my parent record in my child controller like so:

def create
   @article = Article.find(params[:article_id])
   @comment = article.comments.create(comment_params)
   redirect_to "/articles/#{@article.id}/comments/#{@comment.id}"
end

...
private

def comment_params
    params.require(:comment).permit(:commenter, :body)

I would like to do something like redirect_to @comment

Is there a way to do this? Once I did the above I also got an error with this prebaked code from the scaffold creation:

<%= link_to 'Edit', edit_comment_path(@comment) %>

I feel like there is something wrong with my routes maybe or I am not referencing the path for my child correctly.

routes.rb:

resources :articles do
  resources :comments
end

1. How do I redirect to the "show" of my child correctly in the create method of my controller
2. Why would my edit path be broken in my child show view?

thanks

Try below code:

controller

def create
   @article = Article.find(params[:article_id])
   @comment = article.comments.create(comment_params)
   redirect_to article_comment_path(@article,@comment)
end

view

<%= link_to 'Edit', edit_article_comment_path(@article, @comment) %>

routes

resources :articles do
  resources :comments
end
