Question

我正在使用paperclip，devise，aws和heroku在我的Rails应用程序上显示我的照片。它工作正常，直到我更改了我的app / assets / application.js和我的controllers / users / sessions_controller.rb

注意：我没有更改config / environments / production.rb中的内容

但是当我使用heroku run rails console时，我收到语法错误消息。

Running rails console on ⬢ immense-spire-90312... up, run.8450 (Free)
/app/vendor/bundle/ruby/2.2.0/gems/activesupport-5.0.0.1/lib/active_support/dependencies.rb:293:in `require': /app/config/environments/production.rb:88: syntax error, unexpected '\n', expecting => (SyntaxError)
/app/config/environments/production.rb:92: syntax error, unexpected ':', expecting keyword_end
storage: :s3,
        ^

在我的config / environments / production.rb

中

config.paperclip_defaults = {
  Paperclip::Attachment.default_options[:url] = ':s3_domain_url'
  Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'
  Paperclip::Attachment.default_options[:s3_host_name] = 's3-eu-central-1.amazonaws.com'

  # The syntax error seems to be here: 
  storage: :s3,
  s3_credentials: {
    bucket: ENV.fetch('S3_BUCKET_NAME'),
    access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'),
    secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'),
    s3_region: ENV.fetch('AWS_REGION'),
  }
}

我改变了什么：

在javascripts / application.js中，我把// = require引导程序放在jquery_ujs下面（最初位于底部）

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require turbolinks
//= require owl.carousel
//= require_tree .

我已经在设计中创建了一个sessions_controller，这样当用户登录时，我想要更改数据库中的内容

class Users::SessionsController < Devise::SessionsController

  def create
    super do |user| 
      user.randomized_fakeposts.delete_all
      # Note: A fakeposts consists of an image_url which is taken from aws.
      Fakepost.all.each do |fp|
        user.randomized_fakeposts.new(fakepost: fp)
      end
      user.save
    end
  end
end

我查看了您的代码，发现这是您的production.rb代码的语法错误。

您正在使用哈希但最后错过了逗号（，）。所以请用以下代码替换你的代码。

config.paperclip_defaults = {
  :url => ':s3_domain_url',
  :path => '/:class/:attachment/:id_partition/:style/:filename',
  :s3_host_name] => 's3-eu-central-1.amazonaws.com',

  # The syntax error seems to be here: 
  storage: :s3,
  s3_credentials: {
    bucket: ENV.fetch('S3_BUCKET_NAME'),
    access_key_id: ENV.fetch('AWS_ACCESS_KEY_ID'),
    secret_access_key: ENV.fetch('AWS_SECRET_ACCESS_KEY'),
    s3_region: ENV.fetch('AWS_REGION'),
  }
}

Rails：在heroku上使用paperclip和aws语法错误
