rails override default getter for a relationship (belongs_to)
alias_method is your friend here.
alias_method :original_bar, :bardef bar self.original_bar || Bar.lastendThe way this works is that you alias the default "bar" method as "original bar" and then implement your own version of "bar". If the call to original_bar returns nil then you return the last Bar instance instead.
i found that using "super" is the best way
def bar super || Bar.lastendI hope this helps you :D
Randy's answer is spot on, but there's an easier way to write it, using alias_method_chain:
def bar_with_default_find self.bar_without_default_find || Bar.lastendalias_method_chain :bar, :default_findThat creates two methods - bar_with_default_find and bar_without_default_find and aliases bar to the with method. That way you can explicitly call one or the other, or just leave the defaults as is.
