我正在尝试由 railcasts.com Jquery文件上传提出的多文件上传。我已经遵循了测试,但是似乎每次刷新服务器时,都看不到任何东西,并且在以下浏览器中我得到了这个
- 谷歌:空白图标
- 火狐: 文本 "/assets/
我的文件夹中似乎没有上传任何内容。我希望我的图片上传的地方是公开/上传/:imageid
这是我的代码上传者
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
视图
<div><%= image_tag(ad.aimage_url(:thumb)) %></div>
我错过了一步吗?
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
查看索引.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()
对我来说看起来一切都很好!
您的上传器是否已安装到您的模型上?如果没有,请尝试此操作
mount_uploader :image, AimageUploader
并且,在您看来,设置多个选项
<%= f.file_field :image, multiple: true, name: "model_name[image]" %>
我建议你使用回形针
创建一个名为 Image 的模型,如下所示:
class Image < ActiveRecord::Base
has_attached_file :file
end
假设用户模型将有多个图像:
class User < ActiveRecord::Base
has_many :images
end
您可以使用单独的image_controller来处理文件上传
