不允许的参数：avatar甚至我已经允许它在我的控制器中

标签： ruby-on-rails ruby-on-rails-4 carrierwave

我在我的应用程序中使用了carrierwave，但是有些原因我收到了这个错误 - ＆gt; Unpermitted parameters: avatar甚至认为我允许了参数。

我将nested_form与Single Table Inheritance

一起使用

这里是代码 - ＆gt; removed_url

以下是服务器日志：

我允许alerts_controller，people_controller和images_controller

中的参数

我提到的第二个问题是，我已经提到要上传的目录

def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

我想看到图片上传到我的c盘的'uploads/'文件夹？我的avatar_uploader.rb文件中有storage :file

请让我知道我做错了什么？第一次在这里使用Carrierwave

任何有助于欣赏

1 个答案:

答案 0 :(得分：2)

从:multiple => true

删除 alerts/app/views/alerts/_victim.html.erb选项

目前，file_field的{​​{1}}似乎是：

avatar

您的<%= p.file_field :avatar, :multiple => true, class:'form-control input-normal' %> 应如下所示： 

file_field

在提交表单时，<%= p.file_field :avatar, class:'form-control input-normal' %> 选项:multiple => true字段将发送为:avatar。

但是根据你的params哈希，你不期待一个数组，所以你收到Array
