How call Render XML in command line?

Hey, Guys!

I have next action in controller products:

def who_bought
    @product = Product.find(params[:id] )
    respond_to do |format|
      format.html
      format.xml { render :xml => @product.to_xml( :include => :order )
}
      format.json {render :json => @product.to_json(:include => :order )
}
    end
  end

routes.rb
.......................
resources :products do
    get :who_bought member: :on
  end
..........................

I want check, how work in xml format. How me call in command line my
format xml? (format.xml { render :xml => @product.to_xml( :include =>
:order ) })

I guess you want to see what's the output in rails console
Just open it and then do

Product.find(SOME_ID).to_xml

then you'll get the info

For example i can see in command line: curl --silent
http://localhost:3000/products/3/who_bought.atom.builder.

And how me call in command line format.xml?

pass accept header in curl: -H ``"Accept: application/xml"

i add curl --silent http://localhost:3000/products/3/who_bought -H
"Accept: application/xml"

show error: <h1>
  NoMethodError
    in ProductsController#who_bought
</h1>
<pre>undefined method `order&#x27; for #&lt;Product:0xb6196084&gt;</pre>

<p><code>Rails.root: /home/dima/RubyOnRails/Projects/depot</code></p>

its my product.rb:

class Product < ActiveRecord::Base
has_many :line_items, dependent: :destroy
has_many :orders, through: :line_items

before_destroy :ensure_not_referenced_by_any_line_item

  attr_accessible :title, :description, :image_url, :price

  validates :title, :description, :image_url, :price, :presence => true
  validates :price, numericality: {greater_than_or_equal_to: 0.01}
  validates :title, uniqueness: true
# validates :image_url, allow_blank: true, format: {
   # with: %r{ \.(gif|jpg|png)$}i,
   # message: 'gif, jpg png. '
  #}
#validates :image_url, :uniqueness => false

  def ensure_not_referenced_by_any_line_item
    if line_items.empty?
      return true
    else
      errors.add(:base, " have products line")
      return false
    end
  end

end

According to that url you're going to action "who_bought" on
"products_controller"
and the problem is inside that action

<pre>undefined method `order&#x27; for #&lt;Product:0xb6196084&gt;</pre>

It seems you are doing Product.order, but your model says that you have a
has_many relation with orders
so it should be Product.orders (maybe I'm wrong I'm not sure what's inside
your "who_bought" action)

Sorry, I haven’t seen the action that you post in the beginning

def who_bought

@product = Product.find(params[:id] )
respond_to do |format|

  format.html
  format.xml { render :xml => @product.to_xml( :include => :order )

}
format.json {render :json => @product.to_json(:include => :order )

}
end

end

It should be @product.to_xml(:include => :orders)

Note the plural

yea) I just do not notice. Thanks for your help!
