Rails - Mar 2006 - trouble adding to database (stringify_keys)

I''m brand new to rails and am trying to build a simple ajax email 
collection form.  It''s just a coming soon sort of thing where the user 
can enter his email address in the field, hit submit, and the ajax form 
dumps the email into the database and says "success" unless the email
is
blank or not unique in which case it says "failure."

The trouble is, no matter what I seem to do, when I actually go to 
create the new row in the database, I get the same error:

undefined method `stringify_keys!'' for "test@test.com":String

I''ve tried messing with .to_s but that doesn''t help. 
Searching on
google for that error message hasn''t turned up anything helpful. 
I''m
really stuck and would greatly appreciate some help

Thanks,

Aaron Powell

Aaron,
  I seem to be having the same problem with a call to update_attributes({})
after upgrading to rails 1.1.  I''ll let you know after I poke around
and
figure it out.

Thanks for the help.  I was having the same trouble before upgrading so 
I don''t know that it''s directly related for me.

For the record, here''s the code I have in my
"splashpage_controller.rb"
file:

------------------

class SplashpageController < ApplicationController
  def addemail
    newemail = NotifyEmail.new
    newemail.attributes = @params[:notify_email]

    if @notify_email.save
      render(:partial => ''emailfailure'')
    else
      render(:partial => ''emailsuccess'')
    end

    # @notify_email = NotifyEmail.new(params[:notify_email])
    # if params[:notify_email] == "fail"
    #   render(:partial => ''emailfailure'')
    # else
    #   render(:partial => ''emailsuccess'')
    # end
  end
end

------------------

and the form:

------------------

<%= form_remote_tag(
		:name => ''email_signup'',
		:url => {:action => ''addemail''},
		:update => ''result'',
		:complete 	=> visual_effect(:shake, ''result'')
		) %>

	<label for="emailaddress">Email Address:</label>
	<%= text_field_tag :notify_email %>
	<%= submit_tag "Get Notified" %>

	<div id="result">Enter your email.</div>

<%= end_form_tag %>

------------------

trying either of the database update blocks in the controller gives the 
same error.

Aaron,
  Your main problem is that you are using attributes= which expects a hash
yet you are passing in a String.
  What you should do is use text_field(:notify_email, :email) instead of
text_field_tag (see docs).

So your form should look like this:
<%= form_remote_tag(...)

       <label for="notify_email_emailaddress">Email
Address:</label>
       <%= text_field :notify_email, :emailaddress %>
      ...
<%= end_form_tag %>

and your controller should look like:
def addemail
   @notify_email = NotifyEmail.new(params[:notify_email])

   if @notify_email.save
     render(:partial => ''emailfailure'')
   else
     render(:partial => ''emailsuccess'')
   end

 end
