That's what I meant to convey. I think the standard is something like:
```erb
<% if flash[:error] %>
  <h2><%= flash[:error] %></h2>
  <ul>
    <% @user.errors.full_messages.each do |msg| %>
      <li><%= msg %></li>
    <% end %>
  </ul>
<% end %>
```

Personally I'm not wild about this style of error display, and definitely think it benefits from some simple JS validations beforehand, but both of those are up to the rest of the team.
