I dug through the code and it seems I can add my secret_key so Amazon::Ecs can generate a signature. However, it seems Amazon::Ecs.options.secret_key never gets set. I'm not sure if this is a problem with Amazon:Ecs or with AAAP but I couldn't find anything about it on the web so I'm thinking it's AAAP-related. – Any ideas? @Jose I've had a problem with AAAP before and turned out I was using integers instead of strings for my ISBN numbers. I can't say if that would be your problem without seeing the rest of the code, but I thought I'd share it anyway. As of August 15th, Amazon requires a signature for a item_lookup request.

I’ve been trying to set this up to work with a Video search index and UPC lookup instead of ASIN.

I got it working once (have no idea how) but it broke and haven’t been able to get it running correctly again.

Here are my model arguments:

acts_as_amazon_product :access_key => ‘XXXXXXXXXX’, :associate_tag => ‘XXXXXXXXXX’ ,:search_index => ‘Video’, :auto_load_fields => {:title => ‘title’, :upc => ‘upc’,
:category => ‘binding’, :asin => ‘asin’,
:description => ‘content’, :poster => ’smallimage/url’, :poster_url => ‘mediumimage/url’,
}

and my view:

<tr class=”">

<img src= “”>

[..........]

Error: NoMethodError in Peliculas#index

Showing app/views/peliculas/index.html.erb where line #16 raised:
You have a nil object when you didn’t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.valid?

16:

Console:
No known attributes to search by

Help will be greatly appreciated!!
