Rspec的驗證唯一性範圍

Question

我有這個在我的生產線示範

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

我有這個在我的規格

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

我得到這個錯誤...

失敗：

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，爲什麼這是失敗？

Answer 1

我認爲你需要做到這一點讓它通過

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

是「已拍攝的」獨特的默認的錯誤消息。
