error_messages

At: Getting Started with Rails — Ruby on Rails Guides

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.

I can google it, but most of the results show error_messages_for.

That's ok - they're basically the same. error_messages is just the form_for version of error_messages_for.
