我的嵌套形式：
<%= f.simple_fields_for :photos do |build| %>
<%= render "billeder", :build => build %>
<% end %>
和_billeder：
<%= build.simple_fields_for :photo do |d| %>
<%= d.file_field :image, :label => 'Image', :style => 'margin-bottom:2px;float:left;width:250px;' %>
<% end %>
有什么原因可以不上传图片？它们是用值NULL NULL和NULL创建的。
UPDATE：
控制器代码kampagners：
def new
@kampagner = Kampagner.new
2.times {@kampagner.photos.build }
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @kampagner }
end
end
def create
@kampagner = Kampagner.new(params[:kampagner])
respond_to do |format|
if @kampagner.save
format.html { redirect_to(:kampagners, :notice => 'Kampagner was successfully created.') }
else
format.html { render :action => "new" }
end
end
end
的Kampagner模型：
class Kampagner < ActiveRecord::Base
has_many :photos
accepts_nested_attributes_for :photos
attr_accessible :titel, :budget, :photos_attributes, :ppc, :sem, :soc, :cashback,
:landing_page, :budget, :prisklik, :t1, :t2, :t3, :t4, :t5,
:kampagne_beskriv, :kampagne_maal, :email, :image_url, :billed_navn, :photos, :image, :photo
end
的照片模式：
require 'open-uri'
class Photo < ActiveRecord::Base
belongs_to :kampagner
attr_accessor :image_url, :billed_navn, :photo
#sadasdasas
Paperclip.options[:command_path] = "/usr/local/bin"
has_attached_file :image,
:path => ':rails_root/public/images/ads/:id/:basename.:extension',
:url => "images/ads/:id/:basename.:extension"
attr_accessible :photos_attributes, :image_url, :billed_navn, :photo, :image, :kampagner_id, :image_remote_url, :image_file_name, :image_content_type, :image_file_size, :image_updated_at, :str
end
形式：
<%= simple_form_for @kampagner, :html => { :multipart => true, :class => 'newform', :style => 'width:100%;' } do |f| %>
<h1 style="margin-top:10px;padding-top:0px;font-size:12px;">Tilføj billeder</h1>
<%= f.simple_fields_for :photos do |build| %>
<%= render "billeder", :build => build %>
<% end %>
<%= f.submit "Opret kampagne", :style => "margin-bottom:20px;" %>
<% end %>
