は一意性検証テストがshoulda

Question

をマッチャーと私は私のachievement_spec.rbにshouldaマッチャを持っていると私はそれを渡すことができません渡し取得できません：

仕様：

- require 'rails_helper' 
    RSpec.describe Achievement, type: :model do 
    describe 'validations' do 
    it { should validate_presence_of(:title) } 
    it { should validate_uniqueness_of(:title).case_insensitive.scoped_to(:user_id).with_message("you 
    can't have two achievements with same title")}  
    it { should validate_presence_of(:user) } 
    it { should belong_to(:user) } 
end 
end 

モデル：

を

- class Achievement < ActiveRecord::Base belongs_to :user 

    validates :title, presence: true 
    validates :user, presence: true  
    validates :title, uniqueness: { 
     scope: :user_id,   
     message: "you can't have two achievements with the same title" 
} 

    enum privacy: [ :public_access, :private_access, :friends_access ] 

    def description_html 
     Redcarpet::Markdown.new(Redcarpet::Render::HTML).render(description) 
end 
end

      Achievement did not properly validate that :title is case-sensitively

      After taking the given Achievement, setting its :title to ‹"an

      well and its :user_id to a different value, ‹nil›, the matcher 
      expected the new Achievement to be invalid and to produce the 
      validation error "you can't have two achievements with same title" on 
      :title. The record was indeed invalid, but it produced these 
      validation errors instead:

上記のエラーを取り除くにはどうすればよいですか？

私は解決策の下にしようとしたが、同じエラーを取得：モデルで

変更：仕様で

validates :title, uniqueness: { 
     case_sensitive: false, 
     scope: :user_id, 
     message: "you can't have two achievements with the same title" 
    } 

変更：

it { should validate_uniqueness_of(:title).case_insensitive.scoped_to(:user_id).with_message("you can't have two achievements with same title") }

あなたはfaを作る必要がある

describe Achievment do 
    context 'validations' do 
    before { FactoryGirl.build(:achievement) } 

    it do 
     should validate_uniqueness_of(:title). 
     scoped_to(:user_id). 
     case_insensitive 
    end 
    end 
end 

あなたの工場、その後：

FactoryGirl.define do 
    factory :achievement 
    title 'some-string' 
    user 
    end 
end
