As your models are written now, you'd have to do...

my_user.person.profile

If you want to abbreviate that, you can define a profile method on User...

def profile
person.profile
end

i defined the profile method still same error i tried it in console also.
can u modify the models so that it can work properly....please.

[Brian Hempel]

I threw your classes into the MongoMapper console (mmconsole command) and it worked fine with the profile method I described.

See: https://gist.github.com/1432429

my_user = User.create(:person => Person.new(:profile => Profile.new))

my_user.profile # => #<Profile _id: BSON::ObjectId('4edc555578fca28259000001')>

yes in console it is working but not in browser is there anything i can do with the controllers,
the error its giving me is

NoMethodError in Dashboards#index

Showing /home/rahul/Rails_projects/staytuned/app/views/dashboards/index.html.haml where line #3 raised:

undefined method `profile' for nil:NilClass

Extracted source (around line #3):

1: - if user_signed_in?
2:   %h1#user_name
3:     = link_to current_user.real_name, root_path
4:     /%span= title_for_page
5:   %h3#latest_message
6:     = my_latest_message

[rahul chandra]

this is the thing that is giving me error

User class-->

  def real_name
    "#{person.profile.first_name.to_s} #{person.profile.last_name.to_s}"
  end

and i changed it to

  def real_name
    "#{self.first_name.to_s} #{self.last_name.to_s}"
  end

then it ll work but i need first and last names of profile...

[Brian Hempel]

Your current_user does not have a person.  Watch out, MongoMapper associations only talk to each other through the database.  If current_user is saved in an instance variable (say, @current_user) and afterwards, separately, you load up a user, add a person, and save it, then the @current_user object may not have the person until you do @current_user.reload.

If that's not the problem, then there's probably a logic error in your application.
