Hi......
I would like to know what i ve done wrong in my association.
I have 4 Models.
user_info
company_info
department
role

Actually i want to get Particular user's company,and which department he
belongs and what role he has...
These inforamtions i would like to get.
So i made association.


class CompanyInfo < ActiveRecord::Base
#-------------------------------------
 has_one :user_info

class UserInfo < ActiveRecord::Base

    belongs_to :company_info
    belongs_to :department
    belongs_to :role
#-------------------------------------
class Department < ActiveRecord::Base

    has_one :user_info
#-------------------------------------
class Role < ActiveRecord::Base

    has_one :user_info
#-------------------------------------
Now i can able to get department information for a paricular user and
role inforamtion for a particular user.
But i m unable to get Company information for a particular user.
What would be the Problem in my case.
Did i made  anything wrong.
Pls help me.

The setup seems to be right, assuming
there is a company_info_id in the user_info table.

Are the records in the database ok and have the
right id?
What code do you use to get the CompanyInfo?
Something like:

@user_info = UserInfo(:first)

That should allow to acces it like that:
@user_info.company_info

It seems all of your "has_one" should be has_many. A company, role and
department should have many users. That might reduce problems with
your associations.
