Important Model Methods

I don't have an object yet

• all Model.all => fetch all the items from the database
• create Model.create(:hour => 1, :emotion => "super stoked")
  => create a new model in the database
• new Model.new => build a new model but don't save it
• first Model.first => fetches the first one
• last Model.last => fetches the last one
• find Model.find(1) => fetches one with the id we give it
• where Model.where(:hour => 1, :emotion => 'happy') => fetch all of models that have the "hour" set to "1"

Ok I have an object

• destroy Model.destroy => delete the item from the database
• update_attributes Model.update_attributes(:hour => 3) => update the attributes on the model
