this is in a file.rb in config/initializers/
and raises the error I said
Did you read my other response about class methods?
Yes but I'm still truing to do that, what do you mean? with
class << self
def error(msg)
super("ERROR------------>"+msg)
end
end # class methods Object.method_name
and where do I have to put this code?
Thanks for patience
Hey no worries - so
class A
def self.error(msg)
#comment - class method 'error'
end
end
your first post had the right idea - only error is a method that
belongs to the Logger instance - not the dynamic instance.
In A I have a method 'error' that belongs to the A instance.
A.new.error
Would result in a NoMethod on the execution of the code.
class A
def error
end
end
A.new.error
Will work now.
You can try this in irb.
You original code had a method that would go on a new instance of
Logger - what you needed was a method 'error' on the Logger instance
( refered to in object oriented programming as a the Logger Class)
When the error mentioned that the method could not be found - it is
because the 'super' version of the method is actually in Logger the
class method error .
Logger.info "assuming we are talking about the same logger•"
