Ruby on rails 在rails应用程序上使用TwitterAPI呈现配置文件图像

当用户使用twitter api登录时，我一直在尝试呈现用户的个人资料图片，但遇到了一些困难。此时没有错误，但图像未渲染

安装了gem“twitter”

这是我的user.rb文件

class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :omniauthable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

has_many :lines

def profile_image_uri(size = :mini)
parse_encoded_uri(insecure_uri(profile_image_uri_https(size))) unless @attrs[:profile_image_url_https].nil?
end

def self.find_for_twitter_oauth(auth, signed_in_resource=nil)


    user = User.where(:provider => auth.provider, :uid => auth.uid).first
    if user
      return user
    else
      registered_user = User.where(:email => auth.uid + "@twitter.com").first
      if registered_user
        return registered_user
      else

        user = User.create(name:auth.extra.raw_info.name,
                            provider:auth.provider, 
                            profile_image_url:auth.uid + "https://pbs.twimg.com/profile_images/2284174872/7df3h38zabcvjylnyfe3_mini.png",
                            uid:auth.uid,
                            email:auth.uid+"@twitter.com",
                            password:Devise.friendly_token[0,20],
                          )
        end

    end
  end

结束

关于我做错了什么，有什么建议吗？

Auth Twitter Profile image url可以通过以下方式提取：

验证[：额外][：原始信息][：配置文件\图像\ url]

我应该把这一行添加到哪个文件？好的，谢谢。这是正确答案的一部分。我将写一个指南，当我完成如何将照片添加到twitter auth时，将其发布在这里。谢谢你的帮助
