ruby-on-rails - CarrierWave 抛出 NoMethodError - `new' :String: 的未定义方法 "file"

Question

我真的被困在这里，我不确定发生了什么。

我正在尝试上传图片，但在提交表单时出现错误:

Started PATCH "/partners/3" for ::1 at 2015-10-19 14:44:45 -0400
Processing by PartnersController#update as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"CELmC1ibFcHCYB0avQk632KZzqvLUb125W2b3F2At3pkeAaL7N/aowlGqrd/+vaFV/RZ78z+/lmJc60hNPtrCw==", "partner"=>{"name"=>"Company", "description"=>"We make stuff", "track_id"=>"3"}, "commit"=>"Update Partner", "id"=>"3"}

  activerecord (4.2.3) lib/active_record/transactions.rb:351:in `block in with_transaction_returning_status'

这是 Controller 中抛出错误的部分:

 # PATCH/PUT /partners/1
  # PATCH/PUT /partners/1.json
  def update
    respond_to do |format|
>>> HERE >>>  if @partner.update(partner_params)
        format.html { redirect_to @partner, notice: 'Partner was successfully updated.' }
        format.json { render :show, status: :ok, location: @partner }
      else
        format.html { render :edit }
        format.json { render json: @partner.errors, status: :unprocessable_entity }

我的合作伙伴 View :

  <div class="form-group">
    <%= f.label :logo_img %>
    <%= f.file_field :logo_img %>
  </div> 

型号:

class Partner < ActiveRecord::Base
  belongs_to :track

  has_one :question

  validates :name, :presence => true
  validates :track_id, :presence => true

  mount_uploader :logo_img, ImageUploader
end

我真的被困在这里，非常感谢任何帮助/评论/输入......

谢谢

原来我在载波初始化器上打错了字'config/initializers/carrierwave.rb'

config.storage = 'file'

应该是

config.storage = :file

捂脸
