Display Posts on Homepage

MikeLangford asked in Rails

I am building a social app and I want to display the content of the /posts page (index.html.erb) on the homepage if a user is logged in.

The code below works just fine on the /posts page to display the list of posts. However, when I try to use it on the Home page it throws the error "undefined method `each' for nil:NilClass"

Any suggestions on how to adjust the <% @posts.each do |post| %> so it works on the Home page? Or, should I direct users to the Posts page with a <% if user_signed_in? %> as a replacement for the home page?

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

  • <%= post.created_at.strftime("%b %e, %Y") %>
    <%= %>

    <%= post.content %>

    <%= link_to 'Show', post %>
    <% if post.user == current_user %>
    <%= link_to 'Edit', edit_post_path(post) %>
    <%= link_to 'Delete', post, method: :delete, data: { confirm: 'Are you sure?' } %>
    <% end %>
    <% end %>

    Hey Mike,

    If you want to list posts on the homepage, you just need to query for them in your homepage's controller action.

    def index
      @posts = current_user.posts if user_signed_in?
    Also if you use Devise, you can actually change the root when a user is logged in which I find to be the most easy option for modifying the homepage when a user is logged in. That way you can point it to any controller action and it'll be separated out nicely.
    # config/routes.rb
    authenticated :user do
      root to: "posts#index"
    root to: "homepage#show"

    You rock Chris! Thank you.

    The second solution of routing to "posts#index" was exactly what I had in mind.
