Question

我有一个带有carrierwave的单个字段的模型用于文件上传。我搜索了谷歌群组，但没有找到一种直接的方法来将文件上传添加到netzke组件。我会很高兴在面板视图中进行常规浏览器文件上传，我不需要任何花哨的东西。

我刚看到其中一个演示文件已上传，Paging表单带有自定义布局。我想我还需要指导如何将它放入Basepack Grid

Answer 1

首先应将文件上传字段添加到Basepack::Form（然后可以单独测试）：

class AttachmentForm < Netzke::Basepack::Form
  def configure(c)
    super
    c.model = "Attachment"
    c.items = [{xtype: :fileuploadfield, name: 'attachment'}]
  end
end

然后您的网格应配置为使用此表单而不是内置表单：

class AttachmentGrid < Netzke::Basepack::Grid
  def configure(c)
    super
    c.model = 'Attachment'
    c.force_fit = true
    c.columns = [:link]
    c.bbar = [:add_in_form, :del]
  end

  def preconfigure_record_window(c)
    super
    c.form_config.klass = AttachmentForm
    c.width = 600
    c.height = 150
  end
end

作为参考，这里也是Attachment模型：

class Attachment < ActiveRecord::Base
  mount_uploader :attachment

  # this is a virtual column referred to from `AttachmentGrid`;
  # can be moved over to grid itself using `getter` in case
  # you object putting HTML into the model
  def link
    "<a href='#{attachment.url}' target='_blank'>#{attachment.file.try(:identifier)}</a>"
  end
end

Netzke上传文件，最好是载波
