Question

我正在使用Carrierwave，Rails上载文件时出现以下错误。

在2018-08-06 10:46:43 +0530的192.168.1.101上启动POST“ / upload_client_input_file？project_id = 7”   由InputFilesController＃upload_client_input_file作为 / 处理     参数：{“ file” =>＃，@ original_filename =“ input.csv.part_1.1”，@ content_type =“ application / octet-stream”，@ headers =“ Content-Disposition：form-data; name = \”文件\“；文件名= \” input.csv.part_1.1 \“ \ r \ n内容类型：application / octet-stream \ r \ n”>，“ project_id” =>“ 7”}   在27毫秒内完成500个内部服务器错误（ActiveRecord：7.9毫秒）
   TypeError（无法投射文件）：
  app / controllers / input_files_controller.rb：61：在“ upload_client_input_file”中

我的模型代码：

class InputFile < ApplicationRecord  
  belongs_to :project
  mount_uploader :file, AvatarUploader
end

我的上传者代码：

class AvatarUploader < CarrierWave::Uploader::Base
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url(*args)
  #   # For Rails 3.1+ asset pipeline compatibility:
  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
  #
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process scale: [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process resize_to_fit: [50, 50]
  # end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  # def extension_whitelist
  #   %w(jpg jpeg gif png)
  # end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end
end

我的控制器代码：

def upload_client_input_file
    params.permit!
    project_id = params["project_id"]
    tempfile = params["file"].tempfile      
    file = CSV.read(tempfile)
    input_file_id = InputFile.find_or_create_by(batch_name: "Test", flag: true, project_id: project_id, file: File.open(tempfile,"r")).id
end

TypeError（无法投射文件）：Rails载波文件上传
