ruby on rails - undefined method `tokens' for "2":String -

i'm new rails , programming , keep getting above error when try view user id "2". i'm using twitter-omniauth , twitter gems view users tweets. have no clue whats wrong, appreciated.

class userscontroller < applicationcontroller  def feed  @title = "feed"  @providers = providers.for(@user)  @user = user.find(params[:id])  feed = feed.new(params[:id])  @timeline = feed.posts(params[:twitter_pagination])  @unauthed_accounts = feed.unauthed_accounts  @poster_recipient_profile_hash = feed.poster_recipient_profile_hash  @commenter_profile_hash = feed.commenter_profile_hash  @load_more_url = feed_content_path(   :twitter_pagination => feed.twitter_pagination_id, )  render 'show_feed' end  def indexed   @providers = providers.for(@user)  end 

these models.

user.rb

class user < activerecord::base  has_one :token, dependent: :destroy  def validate_tokens!   tokens.each(&:validate_token!) end     

feed.rb

class feed  include applicationhelper  def initialize(user)   @user = user   @unauthed_accounts = [] end  private  def twitter_posts(twitter_pagination_id)   twitter_posts = []   if user_has_provider?('twitter', @user)     twitter_timeline = twitter::timeline.new(user)     begin     twitter_posts = twitter_timeline.posts(twitter_pagination_id).map { |post| twitter::post.from(post) }     @twitter_pagination_id = twitter_timeline.last_post_id   rescue twitter::error::forbidden, twitter::error::unauthorized     @unauthed_accounts << "twitter"   end   twitter_posts   else     twitter_posts   end end 

token.rb

class token < activerecord::base  validates :provider, presence: true validates :uid, presence: true  belongs_to :user  def self.by_name(name)   where(provider: name) end  def self.update_or_create_with_twitter_omniauth(id, auth)   token = where(provider: auth["provider"], uid: auth["uid"]).first_or_initialize   token.provider = auth["provider"]   token.uid = auth["uid"]   token.access_token = auth["extra"]["access_token"].token   token.access_token_secret = auth["extra"]["access_token"].secret   token.user_id = id   token.save!   token end 

and in application helper

module applicationhelper  def user_has_provider?(provider, user)   @user.token.by_name(provider).any? end   end 

error:

app/helpers/application_helper.rb:14:in `user_has_provider?' app/models/feed.rb:27:in `twitter_posts' app/models/feed.rb:18:in `posts' app/controllers/users_controller.rb:62:in `feed' 

issue on line: feed = feed.new(params[:id])

def feed   @title = "feed"   @providers = providers.for(@user)   @user = user.find(params[:id])   feed = feed.new(params[:id]) # here @ line!!   @timeline = feed.posts(params[:twitter_pagination])   @unauthed_accounts = feed.unauthed_accounts   @poster_recipient_profile_hash = feed.poster_recipient_profile_hash   @commenter_profile_hash = feed.commenter_profile_hash    @load_more_url = feed_content_path(   :twitter_pagination => feed.twitter_pagination_id,   )    render 'show_feed' end 

it should be:

def feed   @title = "feed"   @providers = providers.for(@user)   @user = user.find(params[:id])   feed = feed.new(@user) # should @user!!   @timeline = feed.posts(params[:twitter_pagination])   @unauthed_accounts = feed.unauthed_accounts   @poster_recipient_profile_hash = feed.poster_recipient_profile_hash   @commenter_profile_hash = feed.commenter_profile_hash    @load_more_url = feed_content_path(   :twitter_pagination => feed.twitter_pagination_id,   )    render 'show_feed' end 

because, feed's constructor expects user object , you're passing params[:id] "2" , hence error: undefined method `tokens' “2”:string.
