Rails: Custom validation message
提问by Ankit Soni
I'm trying to make a simple custom validation message. The validation I'm using compiles and runs fine, but I don't see any change in the message:
我正在尝试制作一个简单的自定义验证消息。我正在使用的验证编译并运行良好，但我没有看到消息中有任何变化：
validates :rating, :inclusion => { :in => 0..5 }, :presence => { :message => " must be within 0-5" }
validates :rating, :inclusion => { :in => 0..5 }, :presence => { :message => " must be within 0-5" }
The message I get is still Rating is not included in the list
我收到的消息还在 Rating is not included in the list
I need to validate that ratingis present and is a decimalbetween 0-5
我需要验证它rating存在并且decimal介于两者之间0-5

Alright, I solved it. This is the validation that works:
好的，我解决了。这是有效的验证：
validates :rating, :inclusion => { :in => 0..5, :message => " should be between 0 to 5" }
validates :rating, :presence => { :message => " cannot be blank" }
and I added this
我加了这个
validates :rating, :numericality => { :message => " should be a number" }
validates :rating, :numericality => { :message => " should be a number" }
