我正在尝试为我的市场控制器创建一个图像库,我能够使用paperclip上传单个图像。我在谷歌上搜索了一下,但没有找到任何解决方案。如何使用paperclip上传多个图像并以画廊形式显示?有什么方法吗?请给我建议。

# app/models/market.rb
class Market < ActiveRecord::Base
has_many :pictures, dependent: :destroy
end
# app/models/picture.rb
class Picture < ActiveRecord::Base
belongs_to :market
has_attached_file :image,
path: ":rails_root/public/images/:id/:filename",
url: "/images/:id/:filename"
do_not_validate_attachment_file_type :image

查看:
# app/views/markets/_form.html.erb
<%= form_for @market, html: { class: "form-horizontal", multipart: true } do |f| %>
<div class="control-group">
<%= f.label :pictures, class: "control-label" %>
<div class="controls">
<%= file_field_tag "images[]", type: :file, multiple: true %>

<div class="form-actions">
<%= f.submit nil, class: "btn btn-primary" %>
<%= link_to t(".cancel", default: t("helpers.links.cancel")),
galleries_path, class: "btn btn-mini" %>
</div>
<% end %>
控制器:
# app/controllers/markets_controller.rb
def create
@market = Market.new(market_params)
respond_to do |format|
if @market.save
if params[:images]
params[:images].each { |image|
@market.pictures.create(image: image)
}
end
format.html { redirect_to @market, notice: "Market was successfully created." }
format.json { render json: @market, status: :created, location: @market }
else
format.html { render action: "new" }
format.json { render json: @market.errors, status: :unprocessable_entity }
end
end
