i have installed file_column plugin and rmagick.
i have a model:
class Core < ActiveRecord::Base
  has_one :forum_topic
  has_many :votes
  has_many :forum_messages ,:through => :forum_topic
  attr_accessible :site,:descriptionm,:image
  file_column :image
...
and in form i have:
<tr>
    <td>USERNAME*:</td>
    <td><%= text_field "user", "name",
"size" => 25, "maxlength" => 25
%></td>
</tr>
<tr>
        <td>ICONA: <font
class=''nota''>(.jpg,.gif,.png)</td>
  <td><%= file_column_field "core", "image" 
%></td>
</tr>
and in action of form i have:
    @user=User.create(params[:user])
    if params[:regions]
      @regions=Region.find(params[:regions])
      @user.regions=@regions
    end
    if @user.save
      @user.image=params[:core][:image]
      @user.save
So it works. the file is uploaded correctly and the record is saved in
db.
If i edit model so:
class Core < ActiveRecord::Base
  has_one :forum_topic
  has_many :votes
  has_many :forum_messages ,:through => :forum_topic
  attr_accessible :site,:descriptionm,:image
  file_column :image, :magick => {
                        :geometry => "400x400",
                        :versions =>
                        {
                             :small => {:crop => "1:1", :size
=>
"62×62!" },
                             :thumb => {:crop => "1:1", :size
=>
"30×30!" },
                             :medium => { :size => "600×600" }
                        }
I receive this error:
Trying to access file_column, but primary key got lost.
The error is at the istruction:
@user=User.create(params[:user])
Why? How i can do?
Thanks
