Rails - Oct 2010 - Nested Resourced, Books > Authors… Creating Records for Authors…

Hello,

I have the following Rails3 nested resource in my routes.rb:

    resources :books do
      resources :authors
    end

My authors table has ID | name | book_id

Given I''m at the URL /books/312/authors/new

I''m having problems getting a new author created for the book....

Here''s my authors controller code:

def create
	@books = Book.find(params[:book_id])
	@author = @book.authors.create(params[:note])
.
.
.
end

My NEW FORM (which I think is the problem, looks like this:

<%=form_for [@book , @author] do |f| %>
.
.
.

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>


When I submit I get the ERROR:
"Couldn''t find Book without an ID"
And the URL changes to "/books/ & NOT  /books/312/authors  ... as
expected


Suggestions? Thank you

Updated the author controller with:

  def new
    @note = Author.new
    @book = Book.find(params[:book_id])
.
.
end

Now the form is creating what seems like the right URL:
<form accept-charset="UTF-8" action="/books/3/authors"
class="new_author" id="new_author"
method="post">
...

But after submitting a new author, it errors with (after hanging for a
while locally):
SQLite3::BusyException: database is locked: INSERT INTO
"authors" .........


thanks

this should look like this

def create
       @books = Book.find(params[:book_id])
       @author = @book.authors.build(params[:author])
        if @autho.save
       blah blah ....

what  you have makes no sense

for this to work in the new action in the controller you must have created
@book and @author like this

def new

@book = Book..find(params[:book_id])
@author = @book.authors.new

if you dont then this [@book , @author]  gets book as nil

post what you do after save, it appears something is wrong in the render
:action => :new section of the create action

What is this? what is note? makes no sense

Now the form is creating what seems like the right URL:

Thanks radhames - that did the trick!

I now have a view here: /books/131/authors/
And I want to each record to link to something like: /books/131/
authors/3333

    <% @authors.each do |author| %>
       <%= link_to ''author.name'', book_author_path(@book,
@author) %>
    <% end %>

but that error''s with: No route matches
{:action=>"destroy", :controller=>"authors"}

I also tried:

    <%= link_to ''author.name'', [@book, author] %>

Problem is the code keeps linking to /authors/3333, not /books/131/
authors/3333

or

[@book, @author]
