# The timestamps plugin is used to automatically fill two database columns
# with the dates and times on which an object was created and when it was
# modified.
plugin :timestamps, :create => :created_at, :update => :updated_at
# Multiple posts can only belong to a single user.
many_to_one :user
one_to_many :comments

# Post#validate() is called whenever an instance of this class is saved or
# updated. For more information on what you can do with this method see the
# following page:
# http://sequel.rubyforge.org/rdoc/files/doc/validations_rdoc.html
#
# If you're used to working with ActiveRecord it's important to remember that
# these validation methods can't be used in a model's class declaration, they
# have to be placed inside the #validate() method.
