Question

This is probably pretty basic, but I’m trying to figure out how to show how many comments a post has in rails, on the post index page of my app.

comments belongs_to post, and post has_many comments

Just not sure how to show on the index page, the amount of comments for each post.

Thanks in advance!

Answer 1

Try this.

<%= post.comments.size %>

You might also be interested in the pluralize method.

<%= pluralize(post.comments.size, 'comment') %>

This will output “3 comments” or “1 comment”, etc.
