我正在尝试 railcasts.com Jquery File Upload 提出的多个文件上传。我已经进行了测试,但是似乎每次我刷新服务器时,什么都看不到,在下面的浏览器中我得到了这个
- 谷歌:空白图标
- 火狐:文本“/资产/
我的文件夹中似乎没有上传任何内容。我希望我的图片成为上传者的地方是 public/upload/:imageid
这是我的代码上传器
class AimageUploader < CarrierWave::Uploader::Base
include CarrierWave::RMagick
include Sprockets::Helpers::RailsHelper
include Sprockets::Helpers::IsolatedHelper
storage :file
def store_dir
"uploads/#{model.id}"
end
version :thumb do
process :resize_to_fill => [200, 200]
end
def extension_white_list
%w(jpg jpeg gif png)
end
end
看法
<div><%= image_tag(ad.aimage_url(:thumb)) %></div>
我错过了一步吗?
模型
# == Schema Information
#
# Table name: ads
#
# id :integer not null, primary key
# name :string(255)
# aimage :string(255)
# created_at :datetime not null
# updated_at :datetime not null
# advertisement_id :integer
#
class Ad < ActiveRecord::Base
attr_accessible :aimage, :advertisement_id, :name
mount_uploader :aimage, AimageUploader
end
查看 index.html.erb
<% @ads.each do |ad| %>
<div><%= ad.name %></div>
<%= image_tag(ad.aimage_url(:thumb)) if ad.aimage? %>
<div>
<%= link_to 'Show', ad %>
<%= link_to 'Edit', edit_ad_path(ad) %>
<%= link_to 'Destroy', ad, method: :delete, data: { confirm: 'Are you sure?' } %>
</div>
<% end %>
<br />
<%= form_for Ad.new do |f| %>
<div><%= f.label :aimage, "Upload advertisement:" %></div>
<div><%= f.file_field :aimage, multiple: true, name: "advertisement[aimage]" %></div>
<% end %>
控制器
class AdsController < ApplicationController
def index
@ads = Ad.all
end
def show
@ad = Ad.find(params[:id])
end
def new
@ad = Ad.new
end
def edit
@ad = Ad.find(params[:id])
end
def create
@ad = Ad.create(params[:ad])
if @ad.save
flash[:notice] = "Successfully created advertisement."
redirect_to root_url
else
render :action => 'new'
end
end
def destroy
@ad = Ad.find(params[:id])
@ad.destroy
end
end
Javascript ads.js.coffee
jQuery ->
$('#new_ad').fileupload()
在我看来一切都很好!
