Hi Alex,

To simplify how you see those methods, you don't necessarily have to
create a new user object. You can use:

user = User.first
.. and then look through the methods for the user object.

The reason why I supplied two different puts statements is so that you
can see the difference between methods for each. One is showing the
methods available to the User "class", while the other is showing
methods available to the User "object".

Look for build_ methods as well as these will not save the record until
you forcibly save the record. It will allow you a little more
flexibility with your getting used to the console.

Also notice that the create_ and build_ methods available to the user
object are usuable with has_one relationships. While the same methods
are usuable with objects from models that have belongs_to relationships.

So, as an example:

has_many :moderators
has_many :topics
has_many :posts
has_one :userprofile

You would see the create_ and build_ methods for a user object only for
userprofile.

user = User.first
user.methods.sort.each do |method|
p method
end

... methods..
... build_userprofile
... create_userprofile
... etc..

Likewise, for topic, if you had:

class Topic < ActiveRecord::Base
belongs_to :user
#...
end

topic = Topic.first
topic.methods.sort.each do |method|
p method
end

... methods..
... build_user
... create_user
... etc..

Test out a brief example just to see what happens:

topic.build_user

As for accessing the table data for each model with has_one or has_many
from the user model..

topics = User.first.topics

And if you want to iterate over the returned array..

topics.each do |topic|
p topic
end
