Question

I made a rails application. I am supposed to implement has_many, belong_to relations between Author, and Location models as follows, and wrote something as:

In models:

class Author < ActiveRecord::Base
  belongs_to :location
end

class Location < ActiveRecord::Base
  has_many :authors
  accepts_nested_attributes_for :authors
end

In location/new.html.erb:

<%= form_for(@location) do |f| %>
  <%= f.label :location_name %>
  <%= f.text_field :location_name %>
  <%= f.fields_for :authors do |a| %>      
    <%= a.label :name %>
    <%= a.text_field :name %>
  <% end %>
<% end %>

My question is, even the location can have many authors, it is showing only one text field for author for the fields_for :authors, then how can I achieve to append as many as text fields for authors according to the user wish?

Can anyone help me please?
