Hi,  
I have a model user.rb, a controller userdata\_controller, methods  
in the controller and respective .rhtml files. I created a  
registration page. Saved into users table and it works fine. But  
sometimes its throwing error as

undefined method `city=’ for #

c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active\_record/  
attribute\_methods.rb:251:in `method_missing' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active_record/ base.rb:2361:in`send’  
c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active\_record/  
base.rb:2361:in `attributes=' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active_record/ base.rb:2360:in`each’  
c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active\_record/  
base.rb:2360:in `attributes=' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active_record/ base.rb:2130:in`initialize’  
app/controllers/matrimony\_controller.rb:124:in `new' app/controllers/matrimony_controller.rb:124:in`useraccount’  
-e:2:in `load’  
-e:2

It assumes that there is no field ‘city’ in table users.  
I confused a lot. It is never working until i restart my mongrel. I am  
not able to predict, when the problem rises.

Any idea? Help me…

Thanks,
