Question

列表#index中的ArgumentError（缺少必需：存储桶选项） 我不确定我需要做什么。我正在使用回形针放入s3。我的错误来自第6行。如果我删除它，我不会得到错误。

<%= image_tag listing.image.url %>

index.html.erb

<div class="center">
<div class="row">
  <% @listings.each do |listing| %>
<div class="col-md-3">
  <div class="thumbnail">
    <%= image_tag listing.image.url %>
    <div class="caption">
      <h3><%= listing.name %></h3>
      <p><%= number_to_currency(listing.price) %></p>
      <%= link_to 'Show', listing, class: "btn btn-link" %>
      <%= link_to 'Edit', edit_listing_path(listing), class: "btn btn-link" %>
      <%= link_to 'Destroy', listing, method: :delete, data: {   confirm: 'Are you sure?' }, class: "btn btn-link" %>
        </div>
      </div>
    </div>
  <% end %>
</div>

<br>

<%= link_to "New Listing", new_listing_path, class: "btn btn-link" %>

模型/ listings.rb

class Listing < ActiveRecord::Base
  has_attached_file :image, :styles => { :medium => "200x", :thumb => "100x100>" }, :default_url => "default.jpg"
  validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/
end

根据纸夹github wiki，bucket配置应该是paperclip_defaults而不是s3 credentials。喜欢：

config.paperclip_defaults = {
  storage: :s3,
  s3_host_name: "s3_us-east-1.amazonaws.com",
  bucket: ENV['AWS_BUCKET'],
  s3_credentials: {
    access_key_id: ENV['AWS_ACCESS_KEY_ID'],
    secret_access_key: ENV['WS_SECRET_ACCESS_KEY'],
    s3_region: ENV['AWS_REGION'], # or ENV['AWS_REGION']
  } 
}
