</div>

At: [Getting Started with Rails — Ruby on Rails Guides](http://edgeguides.rubyonrails.org/getting_started.html)

Under: 7.4 Generating a Controller

In the following:

\<%= form\_for([@post, @post.comments.build]) do |f| %\>  
\<%= f.error\_messages %\>

What is: \<%= f.error\_messages %\>

Is it displaying an error message? But, what and where is the error  
message displayed? And, how can we customize it?

Thanks.

Have a look at [rails error\_messages - Google Search](http://www.google.co.uk/search?&q=rails+error_messages)

I can google it, but most of the results show error\_messages\_for.

And, I just need some clarification on error\_messages

That’s ok - they’re basically the same. error\_messages is just the  
form\_for version of error\_messages\_for.
