NoMethodError in Static_pages#home for method id - ruby-on-rails

Question

Newbie again in Rails. Following Michael Hartl's tutorial on rails and I'm trying to pass the last section and I get this error
undefined method `id' for #<String:0x3794b80>
It comes from my _feed_item.html.erb and I don't understand why I'm getting this error.
<li id="<%= feed_item.id %>">
<%= link_to gravatar_for(feed_item.user), feed_item.user %>
<span class="user">
<%= link_to feed_item.user.name, feed_item.user %>
</span>
<span class="content"><%= feed_item.content %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(feed_item.created_at) %> ago.
</span>
<% if current_user?(feed_item.user) %>
<%= link_to "delete", feed_item, method: :delete, data: { confirm: "You sure?" }, title: feed_item.content %>
<% end %>
</li>
Hey guys, sorry I feel; asleep after.
When reviewing all my controllers I don't particularly see where it was defined however it did work before I started the last task so I don't know what happened in between.
Here is the user_controller
class UsersController < ApplicationController
before_filter :signed_in_user, only: [:index, :edit, :update]
before_filter :correct_user, only: [:edit, :update]
before_filter :admin_user, only: :destroy
def new
#user=User.new
end
def create
#user=User.new(params[:user])
if #user.save
#Handle a save
sign_in #user
flash[:success] = "Welcome to the Sample App!"
redirect_to #user
else
render 'new'
end
end
def show
#user=User.find(params[:id])
#microposts=#user.microposts.paginate(page: params[:page])
end
def edit
#user=User.find(params[:id])
end
def update
#user=User.find(params[:id])
if #user.update_attributes(params[:user])
flash[:success]="Successfully updated your profile"
sign_in #user
redirect_to #user
else
render 'edit'
end
end
def correct_user
#user=User.find(params[:id])
redirect_to(root_path) unless current_user?(#user)
end
def index
#users=User.paginate(page: params[:page])
end
def destroy
User.find(params[:id]).destroy
flash[:success]="User destroyed"
redirect_to users_url
end
def admin_user
redirect_to(root_path) unless current_user.admin?
end
def following
#title="Following"
#user=User.find(params[:id])
#users=#user.followed_users.paginate(page: params[:page])
render 'show_follow'
end
def followers
#title="Followers"
#user=User.find(params[:id])
#users=#user.followers.paginate(page: params[:page])
render 'show_follow'
end
end
micrpost_controller
class MicrpostsController< ApplicationController
before_filter :signed_in_user, only: [:create, :destroy]
def index
end
def create
#micropost=current_user.microposts.build(params[:micropost])
if #micropost.save
flash[:success]="Micropost Created!"
redirect_to root_url
else
#feed_items = []
render 'static_pages/home'
end
end
def destroy
#micropost.destroy
redirect_to root_url
end
def correct_user
#micropost=current_user.microposts.find_by_id(params[:id])
redirect_to root_url if #micropost.nil?
end
end

I got it to work people. The issues was in my micropost model.
def self.from_users_followed_by(user)
followed_user_ids= "SELECT followed_id FROM relationships WHERE follower_id=:user_id",
where("user_id IN (#{followed_user_ids}) OR user_id=:user_id", user_id: user)
end
should have been
def self.from_users_followed_by(user)
followed_user_ids= "SELECT followed_id FROM relationships WHERE follower_id=:user_id"
where("user_id IN (#{followed_user_ids}) OR user_id=:user_id", user_id: user.id)
end
