我是新來的黃瓜測試,我學習BDDSQL錯誤不能在事務內啓動一個事務,同時黃瓜

當我試圖填寫的表格,並創建顯示此sqlite的錯誤記錄,但是當我在瀏覽器中手動嘗試代碼時沒有錯誤。

我使用的鐵軌4

這裏是我的控制器代碼

class Admin::ItemsController < ApplicationController 
    def index 
     @items=Item.all 
    end 

    def new 
     @item=Item.new 
    end 

    def create 
     @item=Item.new items_params 
      respond_to do |format| 
       if @item.save 
        format.html { redirect_to admin_items_path } 
       else 
        format.html { redirect_to new_admin_items_path } 
       end 
      end 
    end 

private 
    def items_params 
     params.require(:item).permit(:name,:price)  
    end 
end 

這裏是我的特性文件

Feature: Manage Items 
    In order to make a store 
    As an admin 
    I want to create and manage items 

    Scenario: Items List 
    Given I go to the new admin item page 
    And I fill in "Name" with "Shampoo" 
    And I fill in "Price" with "50" 
    When I press "Create" 
    Then I should be on the admin items page 
    And I should see "Shampoo" 

和步驟定義

require File.expand_path(File.join(File.dirname(__FILE__), "..", "support", "paths")) 

Given /^I go to the (.+)$/ do |page_name| 
    visit path_to(page_name) 
end 

And /^I fill in "([^\"]*)" with "([^\"]*)"$/ do |field, value| 
    fill_in(field.gsub(' ', '_'), :with => value) 
end 

When /^I press "([^\"]*)"$/ do |button| 
    click_button(button) 
end 

Then /^I should be on the (.+)$/ do |page_name| 
    current_path.should == path_to(page_name) 
end 

And /^I should see "(.*?)"$/ do |arg1| 
    page.should have_content(arg1) 
end 

這錯誤是sh在步驟4中擁有,即,當單擊創建按鈕並且調用項目#創建時。

我不知道代碼有什麼問題,希望有人可以幫忙。

UPDATE:

我想這個問題是在黃瓜護欄了一條反對 https://github.com/cucumber/cucumber-rails/issues/231

更新是否解決了您的問題?如果是這樣,請回答你自己的問題!另外,請提供您收到的完整錯誤信息,可能是堆棧跟蹤? – Dan

不,它沒有修復問題 – pahnin

它看起來像你使用DatabaseCleaner,這默認情況下在事務中運行每個功能。同時,ActiveRecord在保存該項目時自己啓動一個事務。不幸的是,SQLite不支持嵌套事務。

如果你change your DatabaseCleaner strategy:truncation它應該避免這個錯誤。或者,你可以測試一個更強大的數據庫,如PostgreSQL。

感謝您的回答,但現在我得到這個錯誤,所以現在不能真正改變database_cleaner策略工作! :( – pahnin

對不起,你得到的新錯誤是什麼?棄用警告不應該阻止你創建一個記錄,它們只是警告,而不是錯誤。 –

這對我有效。 按照Andy H的建議,編輯您的Gemfile以從github上的最後一個源文件中提取。
