Question

I am trying an ror tutorial and I came across the following line of code:

index.html.erb:

<%= render :partial => @players %>

_player.html.erb:

<% div_for player do %>
<%= player.FNAME %> <%= player.SURNAME %>
<% end %>

players_controller.rb:

def index
    @players = Player.all(:order => "FNAME")
    respond_to do |format|
      format.html
    end
end

I want to modify the index.html.erb so that there is no need for a partial but it’s not working properly.

Please see code below.

index.html.erb:

<% div_for @players do %>
<%= @player.FNAME %> <%= @player.SURNAME %>
<% end %>

NoMethodError in Players#index

This is a direct translation of your code:

<% @players.each do |player| %>
  <% div_for player do %>
    <%= player.FNAME %> <%= player.SURNAME %>
  <% end %>
<% end %>

The render :partial given a collection (@players this case) would walk through the collection one by one and render the partial for you.

But rendering a collection also gives you a counter and spacer template too.
