Rails的4只在生產

Question

我收到的唯一的生產錯誤，指出「符號轉換成String的任何隱式轉換」：

TypeError (no implicit conversion of Symbol into String): 
app/controllers/products_controller.rb:15:in `create' 

下面是來自products_controller.rb文件中的相關代碼（注意線在問題下面是2號線）

def create 
    @product = @category.products.build(product_params) 
    if @product.save 
    flash[:success] = "Product successfully created" 
    redirect_to [@category, @product] 
    else 
    flash[:alert] = "Product not created" 
    render 'new' 
    end 
end 

private 

    def product_params 
    params.require(:product).permit(:name, :description, :url, :category_id, :picture, :price, :social_image) 
    end 

此代碼目前可用於開發和測試環境很好，以前在生產工作（會解釋，因爲低於去年的工作生產版本的變化）。我已經使用diff工具來確認Gemfile.lock在本地和生產機器之間是相同的，以消除這個方面。

注：我以前有文件上傳使用如被看見在的回形針創業板工作：圖片PARAM，但是我最近列入了該模型中，第二個文件上傳（：social_image），並切換上傳方法到Amazon S3通過aws-sdk gem而不僅僅是生產服務器。另外，我已經確認在development.rb和production.rb之間的所有相關設置都是正確的。

Answer 1

在您的production.rb文件中，回形針配置爲:url => :s3_domain_url，而在dev中它是:url => ':s3_domain_url'（注意引號）。看起來好像你可以將整個config.paperclip_defaults移動到application.rb，所以即使在某些事情發生變化時也可以保證相同的設置。

感謝您發佈一個鏈接到回購，順便說一句 - 更容易發現這些東西，當你可以看到整個應用程序。
