Hello everyone  
Trying to use restful\_authentication in my project.  
country\_id,state\_id,city\_id is the attributes of the user model. I  
specified the relation  
has\_many :users in in three of the model files and in the user model  
file specified as belongs\_to :country\_id,belongs\_to :state\_id,belongs\_to  
:city\_id. After that when i tried to save user model error “undefined  
method `to\_sym’ for #State:0x667b258” . when I remove the relation I  
can save the user model . Where I am going wrong? is it possible to  
specify relation ? Pls help.  
Thanks in advance.

the user shouldn’t belong to a state, the user should have\_one :state

and also your belongs to should be :state not :state\_id
