Question

I’m developing a website. I want to show all the posts from all users. But I got the following error message:

undefined method `each’ for nil:NilClass
Extracted source (around line #3):

\app\view\static_pages\home.html.erb:

   <div class="span8">    
     <ul class="microposts">
       <% @microposts.each do |micropost| %>
         <li>
           micropost.content
         </li>

and I’ve already defined in the
\app\controller\static_pages_controller.rb:

class StaticPagesController < ApplicationController

  def home
    if signed_in?
      @micropost  = current_user.microposts.build
      @feed_items = current_user.feed.paginate(page: params[:page])
    end
  end

  def index
    @microposts = Micropost.all
  end
end

What’s missing? I have 310 sample posts in the database already…

Answer 1

What page are you trying to show posts on? If that’s home, then you should modify your home action to load all posts:

def home
  if signed_in?
    @micropost  = current_user.microposts.build
    @feed_items = current_user.feed.paginate(page: params[:page])
  end

  @microposts = Micropost.all
end

Maybe it was the @feed_items you wanted to display on the home page?
