I have a form rendering a partial that i would like to update with a
call to my controller based on user selectable parameters, but when the
AJAX comes back, i get this error message because i cannot pass a form
builder object between the controller and the view:

out the repeated parts of my forms and put them in common/form and

FormBuilder in rjs
I have a page, which renders a partial that contains a ''State'' drop
down list. Upon change, it re-renders the ''City'' drop down, re-
populating it based on selected state_id:
Page: /customer/new.rhtml
<% form_for :customer, :url => customers_path do |f| %>
State: <%= f.collection_select :state_id, State.find(:all), ''id'',

Implementing conditional read-only attributes of ActiveRecord objects
Hello,
my goal is to implement the option of specifying a condition in
attr_protected, attr_readonly and possibly other attribute methods in
ActiveRecord objects.
Rationale (example):
class User < AR:Base
# User should not be able to modify fields any more once they have
been verified
attr_readonly :firstname, :lastname, :gender_id, :birthdate, :if
=> :passport_verified?
# ...
end

boolean button helper
I don''t have a blog, but wanted to share this little bit of code with
other semi-beginners like myself who are still learning to take
advantage of rails features.
Selecting an attribute with a boolean switch is a common pattern in
forms. You can do it with a check box, but radio buttons are more
expressive in some situations and better convey to the user that they
are making a mandatory

Accessing belongs_to objects from a form_for context
In a form_for context, is there a way to access objects that are related
to the primary object with a belongs_to? I think an example will serve
best:
class User < ActiveRecord::Base
belongs_to :person
attr_accessor :username
end
class Person < ActiveRecord::Base
has_one :user
attr_accessor :first_name
end
<% form_for :user do |form| %>

FormBuilder-friendly labels?
I''m trying to find a good way to emit <label> tags inside a form_for()
block, without needing to repeat the name of the instance variable
constantly. Is there a better way to do this than the snippet below,
or do I need to do a little extension to the FormBuilder itself?
<% form_for :long_example_name, @long_example_name,

Accessing Rails helper method with_output_buffer
Hi all,
I cannot figure out how to correctly use the with_output_buffer helper
method (located in ActionView::Helpers::CaptureHelper) inside a custom
FormBuilder.
Below follows a simplified example.
I''m trying to achieve the following behavior in an ERB as suggested in
the form_for helper docs in the Rails source:

Rewriting FormBuilder
Hi,
I want to extend formbuilder to make it output a lable (I know about
labeled_form_helper made by technoweenie), my own formating, and a
couple of extra tags inside the form attribute. I was easily able to
extend form_remote_to. But when I continue to adjust the way elements
are handled I don''t know how to continue. I can''t find the method

form_for, partials, and rjs
Hi there!
Im trying to use rjs templates to add form fields to an existing form.
So for example a user could fill out a form and optionally hit a
link_to_remote and get another set of identical fields to fill before
sending. This would mean he/she could add ex. more than one record in
the same form.
The original form was rendered with form_for and using a partial:

custom form builder
In the API docs I found this:
"You can also build forms using a customized FormBuilder class. Subclass
FormBuilder and override or define some more helpers, then use your
custom builder "
I couldn''t find any further documentation on this. Where can I read more
about this formbuilder class? For starters, where would I define a
subclass of this class?
TIA,
Jeroen

Nested resources form_for problem
Hi,
I have a resource map like this:
map.resources :users do |user|
user.resource :sreg10record
end
So a User is supposed to have (at most) one Sreg10record. The problem
is in the views. I tried following this tutorial:
http://www.akitaonrails.com/2007/12/12/rolling-with-rails-2-0-the-first-full-tutorial
which proposes something like:
<% form_for( [@user, @sreg10record] ) do |f|

form_for with nested shallow route
Let''s say I have:
map.resources :teams do |team|
team.resources :squads, :shallow => true
end
When I want to generate a form_for a squad, I need both the team and
squad for new/create, but only the squad for edit.
This means I need:
edit:
form_for(squad)
new:
form_for([team, squad])
This seems not very dry. Is there a more idiomatic way of doing this?
Right now,

form_for() and name
how can i give name attributes for form_for(), so it will give an output
like <form name="f">. it is because that i need to access the form name
for javascript manipulation.
as far as i know, name can only used in form_tag(), but i currently have
more than 50 forms that built using form_for(). the structure is like
this:

form_for and partials
I''m getting an error in the partial when i try
<% form_for :name do |form| %>
<%= render_partial "#{@current_stage}" %>
<% end %>
So I assume that form_for does not have scope in the partial?
If that is the case what are my solutions...
Do I have to stick a <% form_for in every partial, or do i just change all
my inputs back to text_field
