Hey, Guys!

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
…

get :who_bought member: :on
end
…

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”

NoMethodError

its my product.rb:

has_many :orders, through: :line_items

According to that url you’re going to action “who_bought” on
“products_controller”
and the problem is inside that action

undefined method `order' for #<Product:0xb6196084>

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
