undefined method `each' for nil:NilClass

Hi,

I'm getting a NoMethodError in Stream#index for an undefined method `each' for nil:NilClass. Specifically for line:

  <% @posts.each do |post| %>

Any help is greatly appreciated. Thank you in advance

Stream Controller

class StreamController < ApplicationController
 before_action :set_post, only: [:show, :edit, :update, :destroy]
 before_action :correct_user, only: [:edit, :update, :destroy]
 before_action :authenticate_user!, except: [:index, :show]

 def index
  Post.where(follower_id: current_user.id, followed_id: current_user.id)
 end

end

View stream Index

div class="page-header">
   <center><strong><h1> Stream Page </h1></strong></center>
</div>


<div id="posts" class="transitions-enabled">
   <% @posts.each do |post| %>

    <div class="box panel panel-default">
      <%= link_to image_tag(post.image.url(:medium)), post %>
      <div class="panel-body">
      <%= post.description %><br/>
      <strong><%= post.user.name if post.user %></strong>

      <% if post.user == current_user %>
        <div class="actions">
        <%= link_to edit_post_path(post) do %>
        <span class="glyphicon glyphicon-edit"></span>
            Edit
          <% end %>
        <%= link_to post, method: :delete, data: { confirm: 'Are you sure?' } do %>
        <span class="glyphicon glyphicon-trash"></span>
            Delete
          <% end %>
       </div>
       <% end %>
     </div>
    </div> 

  <% end %>
  </div>

   </section>
 </aside>
 </div>

In your stream controller, you are missing an instance variable. The line should look like this inside your index method:

@posts = Post.where(follower_id: current_user.id, followed_id: current_user.id)

Thanks Maciej. I missed that, smh. :) Now I'm getting a new error 'ActiveRecord::StatementInvalid'. I'm trying to sort through that. Thanks again. I need to pay more attention.
