Question

How do i access the book id in like method from like_book_path(@book),:method=>:post .As you can see,this link is under the book loop.What do i need to do to make like_book_path(@book) carry the book_id and how would i access it in like action?
so far in the view i can get the id through book.id .Any help will be greately appreciated.

View:

<% @books.each do |book|%>
  <%= book.name%>
  <%= link_to "like this book", like_book_path(@book), :method => :post %>
<%end%>

Book controller:

def like
  @book = Book.find(params[:id])
  #other methods to facilitate like functionality   
end

Route:

resources :book do
  member do
    post :like
  end
end

I guess you should replace your loop with:

<% @books.each do |book|%>
  <%=book.name%>
  <%=link_to "like this book",like_book_path(book),:method=>:post %>
<%end%>

the difference is just to use book instead of the non existing @book.
