NameError：未定義的局部變量或方法'後」爲＃<FactoryGirl.Rspec

Question

我嘗試重構我specs.I有觀點規格/視圖/ posts.html.haml_spec.rb

require 'rails_helper' 

describe 'posts/show' do 
    before(:each) do 
    @post = assign(:post, create(:post)) 
    @comments = assign(:comment, Kaminari.paginate_array([ 
     create(:comment, post: @post) 
    ]).page(1)) 
    end 

    it 'renders attributes in <p>' do 
    render 
    end 
end 

和我想要的代碼轉移到工廠規格/工廠/ posts.rb

FactoryGirl.define do 

    factory :post do 
    title Faker::Lorem.word 
    body Faker::Lorem.paragraph 


    trait :with_comments do 
     after(:create) do 
     create_list(:comment, post: post) 
     end 
    end 
    end 
end 

但是當我運行FactoryGirl.create(:post, :with_comments)，殼告訴我一個錯誤

NameError: undefined local variable or method `post' for #<FactoryGirl::SyntaxRunner:0x00000003b44f08> 

怎麼修？

對不起我的英語不好

Answer 1

您沒有通過對象after_create塊。你也沒有;指定要創建的評論數量。改變你的性狀爲：

trait :with_comments do 
    after(:create) do |post| 
    create_list(:comment, <number_of_comments>, post: post) 
    end 
end
