@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.

Thanks for the comment. It’s not clear from this post, but we also built ubExact. The people who had the original idea hired Netphase to bring it to life. After we launched, it turned out to be more difficult than expected for them to find advertisers (possibly due to what was happening in the economy this time last year). I heard that they did a demo a month ago, so there may yet be a future for it.

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!!

Do you happen to know that, now say we have the crawler, how we come up with a list of websites for it to crawl on if we were to index the whole world wide web. Should we run through all ips from 0.0.0.0 to 255.255.255.255 ?

Or is it that the idea is that you give one seed website, a rather big one, and let the spider go link after link until hopefully it includes all webpages? or fail somewhere and try to find another one seed website?

Thanks!

Did you get a chance to look at this issue?

Best,
Marc

I have code like this:

@book = Book.new(:isbn => ‘1856695688′)

Which only works with a handful of ISBN numbers. I tried a lot of different books, all of which are available on Amazon and can be found at their website using the exact same ISBN number I use in my code. But most of the time it can’t find it.

When it can’t find the book, this it what it returns when I access @book.amazon.author:

You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.inner_html

(acts_as_amazon_product.rb:63:in `amazon’)

I’m new to Ruby, but shouldn’t it just return a nil object instead of throwing this error?
I’m probably doing something wrong though

By the way, if it’s easier feel free to email me instead of replying using comments
