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

例如显示这个：

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

而不是：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

解决方法

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,参考 here

只需在config / initializers / simple_form.rb下,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：如果您使用的是带简单表单的bootstrap,则更改simple_form_bootstrap.rb
