Question

在我的rails 4应用程序中，我有一个名为ListingInformationForm的模型。在这种形式中，我希望用户上传他们工厂的徽标和图片。我在AWS S3上使用paperclip gem。目前，当我提交表单时，它将第二个图像（loan_image）的AWS S3链接保存到徽标和loan_image。

listing_information_form.rb

class ListingInformationForm < ActiveRecord::Base
  # Image uploading
  has_attached_file :logo,
                        :styles => { :medium => "300x300>", :thumb => "100x100>" },
                        :storage => :s3, 
                        :url => ":s3_domain_url",
                        :path => "images/:class/:id.:style.:extension"
  has_attached_file :loan_image,
                        :styles => { :medium => "300x300>", :thumb => "100x100>" },
                        :storage => :s3, 
                        :url => ":s3_domain_url",
                        :path => "images/:class/:id.:style.:extension"
  # Assocations
  belongs_to :business
end

new.html.erb

<%= form_for @listing_information_form, url: business_listing_information_form_path(@user), :html => { :multipart => true } do |f| %>
    <%= f.hidden_field :business_id, :value => @user.id %>
    <%= f.hidden_field :loan_id, :value => @loan_id %>
    <div class="reg-header">
        <h2>Tell us about your business.</h2>
        <p>The application will only take 10 minutes of your time!</p>
    </div>
    <div class="row">
        <div class="form-group">
            <div class="col-md-5">
                <%= f.label :logo, :class => "control-label required" %>
            </div>
            <div class="col-md-7">
                <%= f.file_field :logo %>
            </div>       
        </div>
    </div>
    <div class="row">
        <div class="form-group">
            <div class="col-md-5">
                <%= f.label :loan_image, :class => "control-label required" %>
            </div>
            <div class="col-md-7">
                <%= f.file_field :loan_image %>
            </div>       
        </div>
    </div>
<% end %>

listing_information_forms_controller.rb

def listing_information_form_params
    params.require(:listing_information_form).permit(:business_id, :loan_id, :logo, :loan_image)
end

Answer 1

我想这是因为logo和loan_image的'path'属性都是相同的：

:path => "images/:class/:id.:style.:extension"

将它们更改为：

:path => "logos/:id.:style.:extension"

用于徽标

和

:path => "loan_images/:id.:style.:extension"

贷款图片

使用回形针将两个不同的图像上载到一个模型
