我创建了一个带有轨道的博客应用程序，包括回形针、aws-sdk gems。在我的应用程序中，部署在 Heroku 上，在创建或更新帖子时，它给出了Errno::ECONNREFUSED错误并且帖子没有创建或更新。
另一方面，我已经设置了所有需要的东西，比如 S3、回形针、db。通过表单上传的图片似乎已被处理，甚至可以在 AWS S3 存储桶页面上看到，但不适用于应用程序。我需要警告应用程序中没有与搜索或邮件功能相关的内容。这是我在 Heroku 上的应用程序的完整跟踪：
posts_controller.rb：
def create
@post = current_user.posts.new(post_params)
respond_to do |format|
if @post.save
format.html { redirect_to @post, notice: 'Post was successfully created.' }
format.json { render action: 'show', status: :created, location: @post }
else
format.html { render action: 'new' }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
错误输出：
