Question

我真的被困在这里，而且我不确定是怎么回事。

我试图上传图片，但是当我提交表单时，我收到错误：

这是控制器中抛出错误的部分：

 # 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 }

我的合作伙伴认为：

  <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...

原来我在carrierwave初始化器上输了一个错字 '配置/初始化/ carrierwave.rb'

config.storage = 'file'

应该是

config.storage = :file

面掌

CarrierWave抛出NoMethodError - 未定义的方法`new＆＃39; for＆＃34; file＆＃34;：String：
