CarrierWave在文件列中保存NULL [英] CarrierWave save NULL at file column

问题描述

我使用称为上载类的Photo模型。

im using model called Photo that references Uploader class..

class Photo < ActiveRecord::Base
  attr_accessible :title, :album_id
  belongs_to :album
  mount_uploader :photo_image, PhotosUploader
end



class Album < ActiveRecord::Base    
  attr_accessible :title, :autor, :photos_attributes
  has_many :photos, :dependent => :destroy
  accepts_nested_attributes_for :photos  
end

但是当我尝试用图像保存新专辑（或进行编辑等），而不保存文件（列photo_image保存为NULL且文件也未存储。）

but.. when i try to save new Album (or edit, whatever..) with image it not save a file (the collumn photo_image is saved as NULL and file not stored too.

... views / albums / _form.html.erb

... views/albums/_form.html.erb

<%= f.fields_for :photos do |f| %>
    <div class="field">
    <%= f.label :photo_image %><br />
        <%= f.file_field :photo_image %>
    </div>
<% end %>

推荐答案

只需尝试将：photo_image 添加到 attr_accessible 在Photo模型中，也许可以为您提供帮助。

just try to add :photo_image to attr_accessible at Photo model, it's maybe could help you.
