Can not access model attributes in render partial on Rails 3 - ruby-on-rails

Question

js.erb
$('#search_div').html('<%=j render :partial=> 'find_book',locals: { book: #results }, :formats => :html %>')
html.erb
<% #book=book %>
<%= #book.inspect %>
<% #book.id %>
When I do inspect it works find and show me
[#<Book id: 55, name: "consequatur laborum quidem excepturi", isbn: 9782943127358, price: 4023, comment: nil, created_at: "2013-09-01 02:59:29", updated_at: "2013-09-01 02:59:29", author: nil, sale_type: nil, publisher: nil, sn: nil, category: nil>] [#<Book id: 55, name: "consequatur laborum quidem excepturi", isbn: 9782943127358, price: 4023, comment: nil, created_at: "2013-09-01 02:59:29", updated_at: "2013-09-01 02:59:29", author: nil, sale_type: nil, publisher: nil, sn: nil, category: nil>]
But when I try to use #book.id
it gives me.
ActionView::Template::Error (undefined method `id' for #<Array:0x007faef875b260>):
1: <% #book=book %>
2: <%= #book.inspect %>
3: <% #book.id %>

Answer 1

There is no id because the object book is an Array, not a book object. See the [] around your inspections.
To read attribute of each book, you need to loop on this local variable.
At first some improvements on the code
Use books instead of book as variable name.
Avoid using instance variable when you have local variable available.
Then the code
# JS
$('#search_div').html('<%=j render :partial=> 'find_book',
locals: { books: #results } %>'
# partial: _find_book.html.erb
<% books.each do |book| %>
<%= book.id %>
<%= book.other_attribute %>
<% end %>

Answer 2

As you see, your #book is an array :
[#<Book id: 55, name: "consequatur laborum quidem excepturi", isbn: 9782943127358, price: 4023, comment: nil, created_at: "2013-09-01 02:59:29", updated_at: "2013-09-01 02:59:29", author: nil, sale_type: nil, publisher: nil, sn: nil, category: nil>] [#<Book id: 55, name: "consequatur laborum quidem excepturi", isbn: 9782943127358, price: 4023, comment: nil, created_at: "2013-09-01 02:59:29", updated_at: "2013-09-01 02:59:29", author: nil, sale_type: nil, publisher: nil, sn: nil, category: nil>]
Note the "square brackets" ([]) in the start and end. And ass the error shows you cant call id on the array, either do
#book.first.id etc
or while passing it pass the first result like :
$('#search_div').html('<%=j render :partial=> 'find_book',locals: { book: #results.first }, :formats => :html %>')
Or if your plan is to have multiple object then loop through variable #book to show all the details.
