Hi guys,
I''m having a bit of a frustrating problem -- I''ve got two
models,
drivers and incidents. A driver can have many incidents and the form for
drivers includes a section for incidents (using fields_for). However, a
driver can also have zero incidents, so on the form there is a radio
button that shows/hides the incidents stuff. My problem is that I need
it to validate ONLY if the user has specified that radio button to true.
Here''s what I have set up:
driver.rb
...
has_many :incidents
accepts_nested_attributes_for :incidents, :allow_destroy => true
...
incident.rb
...
belongs_to :driver
bunch of validations
...
drivers_controller.rb (create)
...
params_hash = params[:driver]
unless params[:driver][:suspended_or_revoked] == "true"
params_hash.delete(''incidents_attributes'')
@driver = Driver.new(params_hash)
else
@driver = Driver.new(params[:driver])
end
..
What I try to do is delete the incidents_attributes hash from the driver
params, assuming that since it''s not submitting any data to incidents,
it won''t go through the validations. However, it DOES go through the
validations, regardless of if I have that hash in there or not.
Basically, I''m trying to bypass the validations for incidents (and
prevent creating incident objects) if the driver selected "no" to the
[:driver][:suspended_or_revoked] question. I know that the condition in
the controller is working, as I''ve done some logger.debug stuff to make
sure it''s going to the right blocks.
From what I''ve researched, this is the standard way to do this, but it
doesn''t seem to work (at least in Rails 3.1) .... can somebody point me
in the right direction here?
Any and all help is appreciated :)
Thanks,
- Jeff

Hi Jeff Maybe you should try reading this http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html and check carefully the "reject if" option Hope this can help you On 9 nov, 16:42, Jeff Miller <li...-fsXkhYbjdPsEEoCn2XhGlw@public.gmane.org> wrote:> Hi guys, > I''m having a bit of a frustrating problem -- I''ve got two models, > drivers and incidents.

BAH! I found my problem after looking at my controller code with a fresh mind. After the @driver.save, there was also a @driver.valid? that was determining the type of json response. Ugh... so it was completely unrelated. Well, at least I know all about how nested models work now :) Thanks, - Jeff -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
