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>

36,440 PointsIn 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)

441 PointsThanks 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.
