提交嵌套对象表单时,我无法拒绝它,因为reject_if proc没有看到Paperclip属性。
以下是我的模型和相关部分。形式:
class Stage < ActiveRecord::Base
has_and_belongs_to_many :assets, :uniq => true
accepts_nested_attributes_for :assets, :reject_if => lambda { |attrs| attrs['asset'] }
...
end
class Asset < ActiveRecord::Base
has_attached_file :asset, :path => "#{Rails.root}/public/:attachment/:id/:style/:basename.:extension",
:url => ":attachment/:id/:style/:basename.:extension"
validates_attachment_presence :asset
end
- form_for [@campaign, @stage], :html => {:multipart => true} do |f|
....
- f.fields_for :assets do |asset_form|
- field_set_tag do
- if asset_form.object.new_record?
%h4 New Asset
%p
= asset_form.label :asset, "File"
%br
= asset_form.file_field :asset
%p
= asset_form.label :identifier
%br
= asset_form.text_field :identifier
我在reject_if部分放了一个调试器:
(rdb:1) p attrs
{"identifier"=>""}
我认为这是因为它只查看属性列,但不是它,正如我通过向资产添加attr_accessor所发现的那样
p attrs
{"misc_attr"=>"", "identifier"=>""}
我可以继续使用奇怪的ins&amp;但是我想把它拿出去看看之前有谁遇到过这个问题。
答案 0 :(得分:0)
我不知道这是不是重点,但不应该在Asset类中有一行声明与Stage类的关联,如:
class Asset < ActiveRecord::Base
has_and_belongs_to_many :stages
...
