In a decision I have never undestood，Rails forms by default addaround any field in your form that has validation errors on submission.Which sucks Markaton

<p>
  <div class="fieldWithErrors"><label for="post_title">Title</label></div><br />
  <div class="fieldWithErrors"><input id="post_title" name="post[title]" size="30" type="text" value="" /></div>
</p>

At work we’ve had a hack in place for a while not that dug into Act View and turned off this nonsense.We normally don’t go highlighting form fields with errors anyway.As it turns outhound。

ActionView::Base.field_error_proc = Proc.new{ |html_tag, instance| "<div class=\"fieldWithErrors\">#{html_tag}</div>" }

Just override this proc to return the(only:

ActionView::Base.field_error_proc = proc {|html, instance| html }

In your environment.rb file，that would be：

config.action_view.field_error_proc = proc {|html, instance| html }
