用简单的表单显示完整的错误消息？

Question

如何使用简单表单输出字段的完整错误消息？相当于rails：<%= RESOURCE.errors.full_messages %>

e.g。显示这个：

"Email has already been taken", 
"Password confirmation doesn't match Password", 
"Password is too short (minimum is 8 characters)"

代替：f.error_notification

"has already been taken", 
"doesn't match Password", 
"is too short (minimum is 8 characters)"

simple_form（3.0.2）/ Rails 4.1.1

如果有人仍然想知道现在有一种简单的方法可以做到这一点，如引用here

只需在config/initializers/simple_form.rb将b.user :error更改为b.user :full_error，现在您的错误消息将等同于RESOURCE.errors.full_messages

注意：如果您使用带简单表单的bootstrap，则更改simple_form_bootstrap.rb
