I’ve got a resorts view, shows details of a ski resort. Under the resort  
description I allow users to leave comments on the resort - works fine.

- Resort has many comments.
- Comment belongs to resort.

However, slight problemo - the comment form on my resorts page creates a  
new comment via the Comments Controller (new and create actions are  
available to the public). This works fine.

But how oh how do I send back the comment validation errors to the  
Resorts show view when redirected from the comments controller - I’d  
like to do this.

It’s horrible at the moment - I’m using the flash to display feedback to  
the user, it’s not ideal.

How should I handle this - surely a common situation?

When I redirect back to the resort can I pass back the comment complete  
with any errors?

Basically you can see what I followed here.

> Like many people, the “Creating a weblog in 15 minutes” screencast by DHH is what convinced me to try Rails. Since I have never found a version of this tutorial that works for Rails 2, …

My comments on my resorts in this case are similar to the comments on  
each blog post.

But when this guy redirects back to the @post I can’t see how validation  
errors can be included?  
He just uses the flash?

Please advise.

Thanks

Here’s my existing comments controller create action…

def create  
@resort = Resort.find(params[:resort\_id])  
@comment = Comment.new(params[:comment])  
@comment.resort = @resort  
if @comment.save  
flash[:notice] = “Successfully created comment, it’ll be cleared  
and show up soon on this page.”  
else  
flash[:notice] = “Something went wrong creating your comment.”  
end  
redirect\_to @resort  
end

As you can see, as it stands the second to last line just redirects.

Either you render the resort show action if your create fails or you  
use ajax to update only the comment part of your view.
