I have modified scaffolding code slightly to get three edit actions  
and three update actions.

The requirement: to allow users to edit attributes for the same model  
from seperate forms instead of one form, while using the given  
scaffolding code and performing model validations. I am using  
restful\_authentication with the login email password validations  
defined.

class users\_controller

edit\_email  
edit\_login  
edit\_password

update\_email if update\_attr save else render =\> edit\_email  
update\_login if update\_attr save else render =\> edit\_login  
update\_password @curr\_pass = params[:curr+passs] if update\_attr  
save else render =\> edit\_password

end

i have made routes

edit\_email\_path  
edit\_login\_path  
edit\_password\_path  
update\_email\_path  
update\_login\_path  
update\_password\_path

I can get the update\_email and update\_login to work if I avoid setting  
password validations on update. When i set the password validations  
on update, i can get the update\_password to work, but update\_email,  
and update\_login fail validations because they are trying to validate  
passwords too when there is no form elements for them.

Is there a way to make password validations only run when  
update\_attribute(params[:user]) is called within the update\_password  
controller method and to prevent password validations to run when  
update\_email and update\_login update\_attribute(params[:user]) methods  
are called? Thanks in advance.

@curr\_pass is defined in update\_password for user model user.rb

validate\_on\_update  
User.authenticate(@user.login, @user.curr\_pass)  
errors.add(@curr\_pass, ‘is incorrect’)
