ruby - Rails polymorphic table that has other kinds of associations -


i'm modeling rails 3.2 app , need polymorphic association named "archivable" in table named "archives". no worries it, "archives" table must belongs_to "connections" table. want know if there's constraints rails that.

you can see model here

another detail, connection model has twice user_id foreign key. user_id sender , user_is receiver. possible? think did below won't work...

here models associations.

class user < activerecord::base   has_many :connections, :foreign_key => :sender   has_many :connections, :foreign_key => :receiver end  class connections < activerecord::base   belongs_to :user   has_many :archives end  class archive < activerecord::base   belongs_to :connection   belongs_to :archivable, :polymorphic => true end  class wink < activerecord::base   has_many :archives, :as => :archivable end  class game < activerecord::base   has_many :archives, :as => :archivable end  class message < activerecord::base   has_many :archives, :as => :archivable end

do see wrong or not doable rails?

thank guys.

i think want :

class connections   belongs_to :sender, :class_name => 'user', :foreign_key => 'sender_id'   belongs_to :receiver, :class_name => 'user', :foreign_key => 'receiver_id'  end  class user   has_many :sended_connections, :class_name => 'connection', :as => :sender   has_many :received_connections, :class_name => 'connection', :as => :receiver end

important : don't declare 2 times has_many :connections same name !

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
