Ruby on Rails: StartTLS

Using this feature in ActionMailer (for gmail, for example) requires ruby 1.8.7. If using any earlier, you will get an error similar to

Net::SMTPAuthenticationError (530 5.7.0 Must issue a STARTTLS command first. 14sm4080666ewy.11)

in your logs

Note to Self

If you want a rails model to accept nested attributes, it's really important to have

accepts_nested_attributes_for 

in your model definition.

Otherwise you get the rather cryptic error:

ActiveRecord::AssociationTypeMismatch in YourController#create    

YourDependentModel(#-615375688) expected, got Array(#-605176048)

Ruby Object Model

Dave Thomas's Lecture at Scotland on Rails 2009

• Classes in Ruby are simply objects which hold tables of methods
• IF it can't find a method call, it jumps to the parent
• IF it gets to the top & doesn't find a method call, it goes back to the bottom & looks for a method called methodmissing
• "Singleton Class" - a class any object has as soon as you add a method to it, it's invisible
