Hi,
I am seing a behaviour that I would qualify as strange :) But maybe
that''s due to my lack of understanding of the whole framework (this is
on the works, as I got the book and working on some rails project is
enlightening me :) ).
I am currently working from Rails on SVN, ruby 1.8.2 ...
I have a view that has a link_to_remote that calls an action in
another controller and updates a DIV in that same page (AJAX). That
part works fine.
The action that''s called displays a form. The problem seems to be when
I place "render(:layout => false)" (or pre my latest update
"render_without_layout") in that action, I get errors about a method
that''s not available. But if I ommit this render(:layout => false),
everything is fine.
The action is:
def new
render(:layout => false)
@all_countries = Country.find_all()
@client = Client.new
end
That''s part of my ClientController.
My Client model has:
belongs_to :country
And in the view for "new" I have:
<select id="client_country_id"
name="client[country_id]">
<%= options_from_collection_for_select(@all_countries, "id",
"default_name", (@client.country.id unless @client.country.nil?))
%>
</select>
One of these "country" is generating an error when I am calling the
URL:
NoMethodError in Client#new
Showing /client/new.rhtml where line #17 raised:
undefined method `country'' for nil:NilClass
Extracted source (around line #17):
14: <%= text_field "client", "state", :size => 10
%>
15: <label for="client_country_id">Country:</label><br
/>
16: <select id="client_country_id"
name="client[country_id]">
17: <%= options_from_collection_for_select(@all_countries, "id",
"default_name", (@client.country.id unless @client.country.nil?))
%>
18: </select>
19: <br /><br />
20: <%= submit_tag "Create" %>
Again, if I remove the "render" call, it displays correctly (well,
with the whole layout in that DIV, which is not what I want).
Any hints? :)
Thanks in advance,
/B

If you omit the render call, it''s called implicitly as the last thing in that action (with default parameters, of course). Not sure but I think that might be the source of your problem. You''re now calling render before you have @client set, that''s why the view file bombs. //jarkko -- Jarkko Laine http://jlaine.net http://odesign.fi _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
Thanks Demetrius and Jarkko. It had to be something that simple ... of course, after a whole day of work, coming home and working on this is not the recommended way of doing things :) Thanks again! /B On 6/6/05, Jarkko Laine <jarkko-k1O+Gnc6WpmsTnJN9+BGXg@public.gmane.org> wrote:> Hey Bruno, > > On 6.6.2005, at 14:12, Bruno Mattarollo wrote: > > > > The action that''s called displays a form.
