Question

Sorry for a simple question but i am a bit confused trying to follow ruby on rails tutorial book

I am at the chapter 10 and confused, yes i trick a bit my version for learning purpose
So I have a controller called customer
customers_controller.rb

def show
    @customer = Customer.find(params[:id])
    @posts = @customer.posts
end

I then have the following folder
_post.html.erb

Welcome to a post

Which his called from the show customer file has follow
/view/customer/show.html.erb

<% provide(:title, @customer.name) %>
<aside class="customer_show_nav">
<h1><%= @customer.name %></h1>
<%= @customer.email %>
</aside>

<div class="events">
    <%= render @posts %>
</div>

But when loading nothing his appearing not even Welcome to a post. What i am doing wrong?
Thanks in advance. I am following the tutorial http://ruby.railstutorial.org/chapters/user-microposts#top 10.22

Answer 1

if _post.html.erb is in view/customers

you do this in view/customers/show.html.erb

<%= render 'controller_where_post_lives/post' %> which will look for customers/_post.html.erb

Sometimes, you also need = in <%= %> with rails 3

Also, show is used to show one item, and index is used to show all items.

So to render you will do

<%= render :partial => "post", :collection => @posts %>

Edit:

When you call render you give it the view, no objects here. Unless like above passing a collection.

Also if you just want to render text you can do render :text => "OK"
