how to update multiple models with rails form

I have following two models

class Office < ActiveRecord::Base
    has_many :locations, :dependent => :destroy
end

class Location < ActiveRecord::Base
    belongs_to :office
end

I have a new.html.erb for the office model and the below code in OfficeController

  def create
    @office = Office.new(params[:deal])
    if @office.save
      redirect_to office_url, :notice => "Successfully created office."
    else
      render :action => 'new'
    end
  end

How can I add fields for Location model in new.html.erb of Office?

I want to be able to have fields for locations in the same form.

You'll have to use nested attributes to do this. Fortunately, Rails makes it pretty easy. Here's how to do it:

  1. First, signify to Office that you're giving it Location fields as well by adding this line: accepts_nested_attributes_for :location.

  2. Now, in new.html.erb, add the fields that you want. Say we want to have city and state:

    <%= f.fields_for :location do |ff| %>
    <%= ff.label :city %>
    <%= ff.text_field :city %>

    <%= ff.label :state %>
    <%= ff.text_field :state %>
<% end %>

That's it!
