thanks in advance

model:

class user < activerecord::base   # include default devise modules. others available are:   # :confirmable, :lockable, :timeoutable , :omniauthable   devise :database_authenticatable, :registerable,          :recoverable, :rememberable, :trackable, :validatable, :omniauthable           has_many :posts, dependent: :destroy     def self.find_or_create_from_auth_hash(auth_hash)     find_by_auth_hash(auth_hash) || create_from_auth_hash(auth_hash)   end    def self.find_by_auth_hash(auth_hash)     where(         provider:   auth_hash.provider,         uid:        auth_hash.uid         ).first   end    def self.create_from_auth_hash(auth_hash)     create(         provider:         auth_hash.provider,         uid:              auth_hash.uid,         email:            auth_hash.info.email,         name:             auth_hash.info.name,         oauth_token:      auth_hash.credentials.token,         oauth_expires_at: time.at(auth_hash.credentials.expires_at)         )   end    def password_required?     super && provider.blank?   end    def update_with_password(params, *options)     if encrypted_password.blank?         update_attributes(params, *options)     else         super     end   end    def facebook     @facebook ||= koala::facebook::api.new(oauth_token)   end    def get_profile_info     self.facebook.get_object("me")   end    def get_location     h = get_profile_info["location"]     h ["name"]    end    def get_books     self.facebook.get_connection("me", "books")   end    def get_profile_picture     self.facebook.get_picture(uid)   end  end

view:

<div class="container">     <div class="row">         <div class="col-lg-4">             <div class="media">                 <%= image_tag @user.get_profile_picture, class: "pull-left" %>                 <div class="media-body">                     <h4 class="media-heading"><%= @user.name %></h4>                     <%= @user.get_location %>                 </div>             </div>             <hr />             <div class="books">                 <% @user.get_books.each |book| %>                 <p><%= book["name"] %></p>                 <% end %>         </div></div>          <div class="col-lg-6">             <% @users.posts.order("created_at desc").each |post| %>              <div class="post">                  <h5><%= post.title %></h5>                 <p><%= post.content %></p>                  <span class="pull-right label label-info"><%= time_ago_in_words(post.created_at) %> ago</span>                  <% if post.user == current_user %>                 <span class="pull-left"><%= link_to 'edit', edit_post_path(post), class: "btn btn-xs btn-primary" %> <%= link_to 'destroy', post, class: "btn btn-xs btn-danger", method: :delete, data: {confirm: 'are sure?'} %></span>                 <% end %>             </div>             <% end %>         </div>     </div> </div>

controller:

class userscontroller < applicationcontroller     before_action :set_user, only: [:show]     def index         @users = user.all     end      def show     end      private      def set_user         @user = user.find(params[:id])     end end

i spy 3 candidates.

two in model

def get_location     h = get_profile_info["location"] # <-- here     h ["name"] # <-- here (most likely)  end

one in view

<% @user.get_books.each |book| %>     <p><%= book["name"] %></p> <!-- <-- here --> <% end %>

the accessed facebook data might nil in 1 of places.
