Rails 4 different validations in one model -

i have page 2 tabs (forms), used edit 1 object.

e.g. user's info. in first tab there personal info, in next tab there billing info.

each form has own submit button. how can validate fields separately. if understood right, when i'll try submit form 4 fields (of 10), raise errors, other fields (6 of 10) wrong.

what right way this?

create 2 classes reflect ui:

class user   has_one :user_info   has_one :billing_info end  class userinfo   belongs_to :user    # add validation end  class billinginto   belongs_to :user    # add validation end 

in controller:

def edit   @user = user.find(params[:id])   @user_info = @user.build_user_info   @billing_info = @user.build_billing_info end 

then in views:

= form_for @user_info |f| = form_for @billing_info |f| 

you'll need 2 controllers handle post requests. should named userinfoscontroller , userbillinginfoscontroller respectively.
