undefined method with googlebooks - ruby

Question

I'm building a library in sinatra, using postresql as database and a 'googlebooks' gem to find the informations I want.
This is my code in main.rb
get '/list' do
#books = GoogleBooks.search(params[:title])
erb :list
end
get '/info/:isbn' do
#this is to get the info from my database if there is any
if book = Book.find_by(isbn: params[:isbn])
#book_title = book.title
#book_authors = book.author
#book_year = book.year
#book_page_count = book.page_count
#book_id = book.id
#book_isbn = book.isbn
else
#use the gem to look for the data
text = GoogleBooks.search(params[:isbn])
#book_title = text.title
#book_author = text.authors
#book_year = text.published_date
#book_cover = text.image_link(:zoom => 2)
#book_page_count = text.page_count
#book_notes = text.description
#and then store it into the database
book = Book.new
book.title = #book_title
book.authors = #book_authors
book.publish_date = #book_year
book.image_link = #book_cover
book.page_count = #book_page_count
book.description = #book_notes
book.isbn = params[:isbn]
book.save
#book_id = book.id
end
erb :info
end
This is my erb file :list
<div class='list_by_title'>
<% #books.each do |text| %>
<ul>
<li class='list_by_title'>
<%= text.title %> (Authour: <%= text.authors %>)
</li>
</ul>
<%end%>
</div>
The list part works.. I'm able to have a page with a list of titles... the problem is when I try to call the data from the params isbn, I always have this error:
NoMethodError at /info/0596554877
undefined method `title' for #<GoogleBooks::Response:0x007ff07a430e28>
Any idea for a possible solution?

As per documentation, GoogleBooks::Response is an enumerator. So you need to iterate over it by using each, and invoke the title method on individual objects retrieved from enumerator.
result = GoogleBooks.search(params[:isbn])
result.each do |text|
#book_title = text.title
...
end
Variable name text for details about a book is not a good name, you need to pick apt variable names, many a times good variable names makes debugging easier
