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

ActiveRecord validations and FormBuilder
Hi,
I''m writing my own FormBuilder and I wanted to put an asterisk or
something next to any required fields. The Builder has access to the
AR object, is there any method I can call on the AR object that will
tell me whether or not a particular field is required? Failing that,
can I access the complete list of validations so I can look through
it for instances of

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,

Using render inside a FormBuilder (EdgeRails)
I''m using the latest trunk of 1.2-ish, and I''m wondering how to do what
I want to do. I am using a form_for :builder I wrote, simply called
TableFormBuilder after the rails cookbook, and want to be able to
present help icons automatically. I want these icons to appear next to
form fields I am rendering.
For example, I have this method in helpers/table_form_builder.rb:

Thanks.

Custom method in Application Controller
Hi All,
I took this idea Christian Hellsten and Jarkko Laine''s "Beginning Ruby
on Rails E-Commerce".
Here is the situation. I will be using the
"options_from_collection_for_select" and "collection_select" form helper
methods in my view to render drop-down selection lists for City and
State that have corresponding city_id and state_id foreign key

Non model cascading selects
In my model I have a city_id. ON the form I am using a cascading select
to select the state, which then does a remote_submit to get the list of
cities (and hence the city_id) for the selected state. The problem that
I am having is that if I make a selection, hit SUBMIT and validation
fails, the original selected state/city is now reset (ie, the values
aren''t saved). Since they

Assigning to the foreign key on a belongs_to association
I''ve encountered what seems like an odd omission in the behaviour of
belongs_to associations: if you assign to the foreign key attribute,
it doesn''t update the associated object (or mark a previously loaded
one as stale) until you explicitly save or reload it.
Let''s say we have a Company model, which belongs_to :city :

form and pagination question
Hello,
How do I get params from a form to use with a paginator?

Question About Rails.cache and find method.
The DB load on my site is getting really high so it is time for me to
cache common queries that are being called 1000s of times an hour
where the results are not changing.
So for instance on my city model I do the following:
def self.fetch(id)
Rails.cache.fetch("city_#{id}") { City.find(id) }
end
def after_save; Rails.cache.delete("city_#{self.id}"); end;

View spec response has no content?
I have been messing with this all night, and can''t figure out what''s going
wrong here. I have a test that renders the view, and then a shared
behavior checks "response" for the various tags from a rails layout. The
problem is matching. If I run in the browser the page renders
fine. Is there a way to output what the response contains? Here are my

Specifying custom rails FormBuilders

sure where it should live or how to include the right rspec_on_rails

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
