RSpec文件上傳引發標題行'未定義的方法'

Question

我有一個rails 3.2.16應用程序，它有一個模型和控制器來上傳包含客戶詳細信息列表的csv文件。在應用程序本身這工作正常，但我無法讓測試工作。

我基本上得到，說

undefined method 'first_name,last_name,address_1,address_2,city .... etc.' 

錯誤所以它試圖使用CSV文件的第一行作爲一種方法...？

我正在使用的文件顯示如下

規範（註釋掉線顯示，我一路上試過的東西被看見在SO等問題）

it "upload a file with correct properties" do 
    #include Rack::Test::Methods 
    # @file = fixture_file_upload(Rails.root.join('spec/fixtures/files/cust-imp-good.csv'), 'text/csv') 
    @file = Rack::Test::UploadedFile.new(Rails.root.join('spec/fixtures/files/cust-imp-good.csv'), 'text/csv') 

    post :create, :customer_import => @file 
    response.should be_success 
end 

上傳模型

class CustomerImport #< ActiveRecord::Base 
    extend ActiveModel::Naming 
    include ActiveModel::Conversion 
    include ActiveModel::Validations 

    attr_accessor :file 

    def initialize(attributes = {}) 
    debugger 
    attributes.each { |name, value| send("#{name}=", value) } 
    end 

    def persisted? 
    false 
    end 

    def save 
    if imported_customers.map(&:valid?).all? 
     valid_ids = true 

     dive_shop_ids = DiveShop.ids_array 
     discount_level_ids = DiscountLevel.ids_array 

     imported_customers.each_with_index do |customer, index| 
     if !dive_shop_ids.include?(customer.dive_shop_id) 
      errors.add :base, "Row #{index+2}: dive_shop_id #{customer.dive_shop_id} is not valid" 
      valid_ids = false 
     end 
     if !discount_level_ids.include?(customer.discount_level_id) 
      errors.add :base, "Row #{index+2}: discount_level_id #{customer.discount_level_id} is not valid" 
      valid_ids = false 
     end   
     end 

     if valid_ids 
     imported_customers.each(&:save!) 
     return_val = imported_customers.count 
     else 
     false 
     end 

    else 
     imported_customers.each_with_index do |customer, index| 
     customer.errors.each do |message| 
      errors.add :base, "Row #{index+2}: #{message}" 
     end 
     end 
     false 
    end 

    end 

    def imported_customers 
    @imported_customers ||= ImportRecord.load_imported_records("Customer", file) 
    end 


end 

從下面顯示的錯誤，我可以看到它在初始化器中失敗。雖然如果我在那裏放置一個調試器，初始化器看起來沒問題。

從調試器輸出內部初始化從rspec的失敗消息

rdb:1 attributes 
Rack::Test::UploadedFile:0x0000000b089a98 @content_type="text/csv", @original_filename="cust-imp-good.csv", @tempfile=#<File:/tmp/cust-imp-good.csv20131212-26548-ynutnh>> 
rdb:1 

輸出

    # ./spec/controllers/customer_imports_controller_spec.rb:20:in `block (3 levels) in <top (required)>' 

任何幫助，將不勝感激我試圖在Undefined Method 'NameOfField' for #<Model:0x000...>即耙所示的解決方案：分貝：測試：準備並bundle exec rspec。但這並沒有工作，要麼

EDIT包括控制器代碼

class CustomerImportsController < ApplicationController 
    before_filter do 
    @menu_group = "diveshop" 
    end 

    def new 
    @customer_import = CustomerImport.new 
    end 

    def create 

    if params[:customer_import] != nil 

     @customer_import = CustomerImport.new(params[:customer_import]) 
     return_value = @customer_import.save # need to add @customer_import.file here 
     if return_value != false  
     addauditlog("A bulk import of customers was carried out") 
     redirect_to customers_url, notice: "Imported #{return_value} customers successfully." 
     else 
     render :new 
     end 
    else 
     flash[:error] = "You have not selected a file" 
     redirect_to new_customer_import_url 
    end 
    end 

end

在創建新模型實例，控制器似乎已經過去了一個哈希作爲參數與它的值是一個關鍵的csv文件的第一行。您需要共享控制器代碼和已更新文件的第一行，以便能夠確認並提供更多信息。
