In your form view change your current code
在您的表单视图中更改您当前的代码
<%@object.errors.full_messages.each do |msg| %>

<%@object.errors.messages.values.each do |msg| %>
<%msg.each do |m| %>

You can use a '^' character at the start of the message value. And it will only show the characters after this.
您可以在消息值的开头使用“^”字符。它只会显示此后的字符。
validates_presence_of :title, :message => "^no title"
You can use the following Gem also

If you change the label of the element it will effect the error message label. So if you change it to a blank string it will render just the message:
如果您更改元素的标签，它将影响错误消息标签。因此，如果将其更改为空白字符串，它将仅呈现消息：
-# reviews/_form.html.haml
= form_for review do |form|
= form.label :rating, (review.errors[:rating] ? "" : "Rate this Item" )
