I am new to Ruby and am pretty sure that this has a very easy  
solution. I am querying an Amazon wishlist but am not sure how to  
display all of the results in the view. Following is the code with  
comments. Any help would be appreciated.

You should investigate the link\_to and image\_tag helpers to help clean  
up  
your views. After you’re comfortable with that the next level would be  
extracting the contents of the loop into a partial.

Hi Mike,

Thanks for the reply. Still getting an error as follows:  
NoMethodError in Amazon#wishlist

Showing app/views/amazon/wishlist.rhtml where line #2 raised:

undefined method `url’ for #Amazon::Search::Response:0x25f3f64  
Extracted source (around line #2):

1: \<% @products.each do |product| %\>  
2: \<%= product.product\_name %\> ![Falling Up]()  
3:   
  
4: List Price: \<%= product.list\_price %\>  
  
5: Our Price: \<%= product.our\_price %\>  
  
RAILS\_ROOT: ./script/…/config/…

Again here are the files:  
amazon\_controller.rb

I am not at all familiar with the Amazon search library. However, it  
appears that your product object does not have a method call url.

Change this line in your controller and you should be good to go.

@products = request.wishlist\_search(‘170YZ2UOWUXV6’,  
weight=HEAVY).products

Many thanks Mike. That .product in the controller did it.
