使用回形针 gem 上传图像时 Heroku Rails 应用程序崩溃答案

【问题标题】：Heroku Rails app crashes when image is uploaded using paperclip gem使用回形针 gem 上传图像时 Heroku Rails 应用程序崩溃

【问题描述】：

您好，我最近刚刚在 heroku 上部署了我的应用程序，我收到一条错误消息，上面写着“我们很抱歉，但出了点问题。”每次我尝试在编辑或创建表单中将头像图像添加到零件时。我安装了以下 gem（回形针和 aws），并且还存储了 Amazon Web 服务凭证。

更新忘了包括我的回形针配置

config.paperclip_defaults = {
    :storage => :s3,
    :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'],
    :s3_region => ENV['AWS_REGION'],
    }

我已经为我的存储桶和所有其他凭据集设置了一个区域。

这是我的一些纸迹记录

宝石

gem 'paperclip'
gem 'aws-sdk', '~> 2.3'

零件模型

class Part < ActiveRecord::Base
  has_attached_file :avatar, styles: {
    thumb: '100x100>',
    square: '200x200#',
    medium: '300x300>'
  }

  validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/

部分视图（创建）

<%= form_for(@part, multipart: true) do |f| %>
<%= f.label :name %>
<%= f.text_field :name %><br>


<%= f.label :description %>
<%= f.text_field :description%><br>

<%= f.label :category_id%>
<%= f.collection_select :category_id, Category.all, :id, :name%><br>

<%= f.label :discount%>
<%= f.number_field :discount%>%<br>

<%= f.label :price%>
<%= f.text_field :price%><br>

<div class="field">
  <%= f.label :avatar%>
  <%= f.file_field :avatar%>
</div>
<%=f.submit %>
<%end%>

如果有人需要更多信息，我很乐意提供更新。

【问题讨论】：

你有安装 rails_12factor 吗？
@ruby_newbie 刚刚安装它，仍然得到同样的错误
@Dan 你运行迁移了吗？你的回形针配置是什么样的？有没有设置区域？另外，请包含更多您的日志，应该有一些比您发布的更有用的信息。
@JamesMilani 是的，我确实运行了迁移，我提供了配置，还提供了一些来自书面记录的更多日志。我也确实设置了一个区域

【解决方案1】：

尝试在不包含其他元素的情况下使您的凭据成为自己的哈希。像这样：

config.paperclip_defaults = {
    :storage => :s3,
    :bucket => ENV['S3_BUCKET_NAME'],
    :s3_credentials => {
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    },
    :s3_region => ENV['AWS_REGION']
}

另外，不要忘记在 heroku 中设置 ENV 变量！

【讨论】：

我在你发布的时候重新做了哈希，甚至重新做了 ENV 变量，但仍然无法工作:(

【解决方案2】：

好吧，事实证明我设置的区域不正确我通过将区域更改为他们正在寻找的正确格式来让它工作
