使用回形针与工厂女孩,没有图像处理程序错误



我正在尝试将回形针与factory_girl宝石一起使用,但得到"找不到处理程序"错误"消息。

test_should_update_category(类别控制器测试): 回形针::适配器注册表::NoHandler错误:找不到"/system/categories/images/000/000/001/original/tel1.JPG?1354197869"的处理程序

工厂女孩档案:

FactoryGirl.define do
factory :category do
name "MyString"
description "MyText"
image { File.new(File.join(Rails.root, 'test','tel1.JPG')) }
end
end

类别迁移 ::---------------

class CreateCategories < ActiveRecord::Migration
def up
create_table :categories do |t|
t.string :name
t.text :description
t.string :image
  t.timestamps
end
add_attachment :categories, :image
end

型:

class Category < ActiveRecord::Base
attr_accessible :description, :image, :name
has_attached_file :image, :styles => { :thumb => "100x100>" }
end

类别控制器测试文件:

require 'test_helper'
class CategoriesControllerTest < ActionController::TestCase
setup do
@category = FactoryGirl.create(:category)
end

我使它在我的应用程序/工厂中使用以下代码:

FactoryGirl.define do
  factory :upload do
    permalink "unique"
    upload Rack::Test::UploadedFile.new(Rails.root + 'spec/files/uploads/unique.jpg', 'image/jpg')
  end  
end

因此,在您的应用程序中,您应该将类别工厂更改为如下所示:

FactoryGirl.define do
  factory :category do
    name "MyString"
    description "MyText"
    image Rack::Test::UploadedFile.new(Rails.root +'test/tel1.JPG', 'image/jpg')
  end
end
