以简单的形式显示完整的错误消息? [英] Show full error messages with simple form?

问题描述

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

How do I output the full error message of a field using simple form? The equivalent of 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)"

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

推荐答案

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 这里

If anyone is still wondering there is an easy way to do this now, as referenced 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

Simply under config/initializers/simple_form.rb change b.user :error to b.user :full_error and now your error messages will be the equivalent of RESOURCE.errors.full_messages

注意:如果您使用带有简单形式的引导程序，您需要更改 simple_form_bootstrap.rb

Note: if you are using bootstrap w/ simple form you change simple_form_bootstrap.rb
