Ruby on rails Rails文件_fieldhelper不';我什么也不退
我用的是简单形式。我有一个用于创建新项目的表单,还有一个用于编辑现有项目的表单。我还为每个项目设置了两个文件字段。困扰我的是,文件字段在创建新项目时显示良好,但在编辑现有项目时,它们根本不会生成 我在Rails 3.0中已经完美地实现了这一点,但现在在Rails 3.2.1中无法实现 表格:Ruby on rails Rails文件_fieldhelper不';我什么也不退,ruby-on-rails,paperclip,attachment,simple-form,Ruby On Rails,Paperclip,Attachment,Simple Form,我用的是简单形式。我有一个用于创建新项目的表单,还有一个用于编辑现有项目的表单。我还为每个项目设置了两个文件字段。困扰我的是,文件字段在创建新项目时显示良好,但在编辑现有项目时,它们根本不会生成 我在Rails 3.0中已经完美地实现了这一点,但现在在Rails 3.2.1中无法实现 表格: <%= simple_form_for @item, :html => { :multipart => true } do |f| %> <%= f.input :ti

基本上,这部分代码不起作用:
<div class="attachment_button">
<% f.fields_for :assets do |asset| %>
<%= asset.file_field :photo %>
<% end %>
</div>
生成的HTML只是空div
同样的代码在创建新项目时有效,但在编辑现有项目时无效
资产和收据都使用回形针存储图像。以下是资产类别的代码:
class Asset < ActiveRecord::Base
belongs_to :item
has_attached_file :photo,
:styles => {
:thumb => "80x80#",
:small => "150x150>" }
validates_attachment_size :photo, :less_than => 550.kilobytes
validates_attachment_content_type :photo, :content_type => ['image/jpeg', 'image/png']
end
class资产{
:thumb=>“80x80#”,
:small=>“150x150>”}
验证\u附件\u大小:照片,:小于=>550.KB
验证附件内容类型:照片,内容类型=>['image/jpeg','image/png']
结束
也许您忘了在您的商品模型中添加这行代码:
accepts_nested_attributes_for :receipts, :allow_destroy => true
accepts_nested_attributes_for :assets, :allow_destroy => true
并添加“=”:
<%= f.fields_for :assets do |asset| %>
<%= asset.file_field :photo %>
<% end %>
<%= f.fields_for :receipts do |receipt| %>
<%= receipt.file_field :photo %>
<% end %>
谢谢,就是缺少的“=”了!我有点认为它会起作用,但在Rails3.2中,规则似乎更为严格。
