ruby on rails app tutorial can't display micropost page - ruby-on-rails-3

Question

Hi I'm following a rails tutorial and i've kind of veered off the tutorial to do some different things...& i hit a snag. So the tutorial (michael hartl's) creates a feed of microposts, but it doesn't give each micropost its own page. This is what i'm trying to do and can't seem to get it working.
So in the feed view which i'm calling "activity" i've got:
<li id="<%= activity_item.id %>">
<%= link_to gravatar_for(activity_item.user, :size => 200), activity_item.user %><br clear="all">
<span class="title"><%= link_to activity_item.title, #micropost %></span><br clear="all">
<span class="user">
Joined by <%= link_to activity_item.user.name, activity_item.user %>
</span><br clear="all">
<span class="timestamp">
<%= time_ago_in_words(activity_item.created_at) %> ago.
</span>
<% if current_user?(activity_item.user) %>
<%= link_to "delete", activity_item, :method => :delete,
:confirm => "Are you sure?",
:title => activity_item.content %>
<% end %>
</li>
And when i click on the actual micropost "title" i get the following error saying i've got "No route matches [GET] "/microposts". I'm sure this is probably an easy fix i'm missing, but I'm a beginner & I've been goin too long & my brain is fried.
What i basically need to have happen is when i click on the title of a micropost from my activity feed...I need it to go to the unique #show page of that micropost id.
Here are the models / controllers i believe are relevant. If i need to post anything else just let me know. I appreciate any and all help! Thanks!
static_pages_controller (the home page is where my activity feed shows up
class StaticPagesController < ApplicationController
def home
if signed_in?
#micropost = current_user.microposts.build
#activity_items = current_user.activity.paginate(:page => params[:page])
#friendactivity_items = current_user.friendactivity.paginate(:page => params[:page])
end
end
def help
end
def about
end
def contact
end
end
Microposts Controller
class MicropostsController < ApplicationController
before_filter :signed_in_user, :only => [:create, :destroy]
before_filter :correct_user, :only => :destroy
def index
end
def new
#micropost = current_user.microposts.build if signed_in?
end
def create
#micropost = current_user.microposts.build(params[:micropost])
if #micropost.save
flash[:success] = "Micropost created!"
redirect_to root_path
else
#activity_items = [ ]
render 'new'
end
end
def show
#micropost = Micropost.find(params[:id])
#users = #micropost.users.paginate(:page => params[:page])
end
def destroy
#micropost.destroy
redirect_to root_path
end
private
def correct_user
#micropost = current_user.microposts.find_by_id(params[:id])
redirect_to root_path if #micropost.nil?
end
end
Micropost Model
class Micropost < ActiveRecord::Base
attr_accessible :content, :title
belongs_to :user
validates :title, :presence => true, :length => { :maximum => 100 }
validates :content, :presence => true, :length => { :maximum => 220 }
validates :user_id, :presence => true
default_scope :order => 'microposts.created_at DESC'
# Returns Microposts from the users that the given user follows
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})",
:user_id => user.id)
end
end
I'm also adding now the routes.rb file and micropost model as requested
routes.rb
SampleApp::Application.routes.draw do
resources :users do
member do
get :following, :followers
end
end
resources :sessions, :only => [:new, :create, :destroy]
resources :microposts, :only => [:create, :destroy, :show]
resources :relationships, :only => [:create, :destroy]
# home page route
root :to => 'static_pages#home'
# signup route
match '/signup', :to => 'users#new'
match '/signin', :to => 'sessions#new'
match '/signout', :to => 'sessions#destroy', :via => :delete
# static pages routes
match '/help', :to => 'static_pages#help'
match '/about', :to => 'static_pages#about'
match '/contact', :to => 'static_pages#contact'
# create a micropost routes
match '/createamicropost', :to => 'microposts#new'

You are getting a routes error - No route matches [GET] "/microposts.
So, it's not related with code as such. Just declare the routes to microposts like this.
config/routes.rb
resources :microposts
