#find_first(options = {}) ⇒ Object
Find the first instance, optionally matching conditions, and specifying order
You can call with just conditions, providing a hash
User.to_adapter.find_first :name => "Fred", :age => 23
Or you can specify :order, and :conditions as keys
User.to_adapter.find_first :conditions => {:name => "Fred", :age => 23}
User.to_adapter.find_first :order => [:age, :desc]
User.to_adapter.find_first :order => :name, :conditions => {:age => 18}
When specifying :order, it may be
-
a single arg e.g.
:order => :name
-
a single pair with :asc, or :desc as last, e.g.
:order => [:name, :desc]
-
an array of single args or pairs (with :asc or :desc as last), e.g.
:order => [[:name, :asc], [:age, :desc]]
