ruby on rails 3 - How to set Mongoid fields from within the class -


i lost scope of variables in rails mongoid. (probably due lack of coffee).

all want, way set fields within application, way can find this, calling write_attribute.

class example   include mongoid::document   field :foo    def bar     @foo = "meh"   end   def hmpf     foo = "blah"   end   def baz     write_attribute(:foo, "meh")   end end  e.bar   #=> "meh" e.foo   #=> nil e.hmpf   #=> "blah" e.foo   #=> nil e.baz   #=> [nil, "meh"] e.foo   #=> "meh"

am using scope wrong? why running foo = "bar" not set field within, works outside: e.foo = "blah" works trough magic methods.

try adding self attribute references when working in model's instance methods:

def hmpf   self.foo = "blah" end

should trick.
