Hi All,

I have 2 tables  
1] user\_infos &  
2] users

class UserInfo  
has\_one :user  
validates\_presence\_of :city

class User  
belongs\_to :user\_info  
validates\_presence\_of :first\_name

i write following code in my create method.

@user\_info = UserInfo.new(params[:user\_info])  
@user=@user\_info.build\_user(:first\_name=\>’’)

if @user\_info.save

else

end

now what i want is to create a object that save data in two table at a  
time and if my first name and city is blank it should throw an error  
that  
user info is not saved because of two errors  
1]City can’t be blank.  
2]Firts name can’t be blank.

Regards,

Salil G.

There is an easier and better way to do the same. Just use Rails  
nested model forms:

Hope this helps,
