Rails - Dec 2005 - NewbieQ : undefined method `stringify_keys!'' Dumb Question

Hi,
I''m running round in circles again! I''m trying to save a note
that has a
HABTM relationship with a job. The note is new - the job exists.
In my partial for notes I have ;

<%= start_form_tag :action => ''new_note'', :id => @job
%>


	  <%= text_area_tag "note", nil, :size => "65x10"
%>

	  <%=submit_tag ''Add Note'', :note => @job.note %>

<%= end_form_tag %>
Which exists on a page containing another partial with job data.

In the controller there is ;

   def dashboard_job_update
     @job = Job.find(params[:id])
	@note = Note.new(params[:note])   <---this is line 99
	@job.notes << @note
     if @job.update_attributes(params[:job]).......

The submitted params are;

Request

Parameters: {"commit"=>"Add Note",
"id"=>"1",
"job"=>{"job_state_id"=>"2",
"current_action_id"=>"7",
"job_phase_id"=>"2",
"job_wait_state_id"=>"4"},
"note"=>"xzczcxvzxcvzxc"}

The error message is;
undefined method `stringify_keys!'' for
"xzczcxvzxcvzxc":String

And the trace is ;
d:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/base.rb:1333:in
`attributes=''
d:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/base.rb:1188:in

#{RAILS_ROOT}/app/controllers/job_controller.rb:99:in `new''
#{RAILS_ROOT}/app/controllers/job_controller.rb:99:in
`dashboard_job_update''

See above for line 99

Can''t find much to explain this error - can anyone help?

Kind Regards,
Eric.

I''m a little confused by how you''re approaching the addition
of the
note.

First of all, in your partial, you have:

<%= start_form_tag :action => ''new_note'', :id => @job
%>

But the action you''re showing us in the controller is 
"dashboard_job_update" not "new_note".  Your action in your 
start_form_tag directly correlates to what method is executed on form 
submission.

Also, and this is the cause of your stringify_keys! error, :note is not 
a valid option for the submit tag.  Its submit_tag(value, options). 
value is whatever you want the Submit button to say and options are 
html-type options, such as :class or :id.

Here''s what I would do instead.  In whatever controller that
corresponds
to the view you''ve given us below define @job (@job = 
Job.find(params[:id])) and define a new note object (@note = Note.new). 
Then use the following for your view:

<%= start_form_tag :action => ''dashboard_job_update''
%>
  <%= text_area_tag "note", nil, :size => "65x10"
%>
  <%= hidden_field_tag "job_ids[]", job.id %>
  <%= submit_tag "Add Note" %>
<%= end_form_tag %>

Then I''d change your controller as follows:

def dashboard_job_update
  @note = Note.new(params[:note])
  @note.jobs = Job.find(@params[:job_ids]) if @params[:job_ids]
  if @note.save ......

You might want to change your method name too because you''re not really
updating a job, you''re creating a note.  Also, are you sure it is a 
HABTM relationship you want?  If you''re only adding each note to one 
job, then note really only needs a belongs_to relationship with job 
(which would require different code than above of course).

If I remember correctly, if you use Note.new with params[:note], then
:note should be a hash containing the paramaters for Note. What Rails
is trying to do is read the hash in :note, but it''s not a hash,
it''s a
string.

Assuming you''re trying to set Note.value, try this instead:

@note = Note.new(:value => params[:note])

changing value to whatever attribute "xzczcxvzxcvzxc" was bound for.

Have a look at the documentation for ActiveRecord:
http://api.rubyonrails.com/classes/ActiveRecord/Base.html

Thanks David, Marc, Ed for the responses. All have been really helpful. 
My problem is turning out to be fairly fundamental insofar as I''m
trying
to run a set of partials, each with it''s own form which, I''m
beginning
to realise, is probably not a great idea. Ultimately what I''m trying to
acheive is my main job data - customer, address, job status, etc.. on a 
main page with stuff like contacts, notes, etc.. on their own forms in a 
tabbed section of the main page.
Eric.
