Rspec的验证唯一性范围

Question

我有这个在我的生产线示范

validates :home_team, :uniqueness => { :scope => [:visiting_team, :event_datetime], 
:message => "** DOUBLE EVENT **" } 

我有这个在我的规格

describe Line do 
    it { should validate_uniqueness_of(:home_team).scoped_to(:visiting_team, :event_datetime) } 

我得到这个错误...

失败：

1) Line 
Failure/Error: 

it { should validate_uniqueness_of(:home_team).scoped_to(:visiting_team, :event_datetime) } 
    Did not expect errors to include "has already been taken" when home_team is set to "arbitrary_string", got error: 
# ./spec/models/line_spec.rb:7:in `block (2 levels) in <top (required)>' 

任何想法，为什么这是失败？

Answer 1

我认为你需要做到这一点让它通过

it { should validate_uniqueness_of(:home_team).scoped_to(:visiting_team, :event_datetime).with_message("** DOUBLE EVENT **") } 

是“已拍摄的”独特的默认的错误消息。
