How to Call a static method?

Ruby
1

Hi there, after I searched the ruby-doc.org site I couldn’t find a hint
how to call a class method on different classes.

I’ve a helper class which parses a text input and which should either
call

Role.something or

Organisation.anotherthing

depening which parameter was passed.

Please give a little hint to proceed. Thanks a lot…

Just do it
if condition
Role.something
else
Organisation.anotherthing
end

Nothing special.

class Test
def self.test
puts “The huge test…OF DOOM!”
end
end
Test.test # => The huge test…OF DOOM!

Test.test isn’t really a static method, but a singleton method on
Test. Then just do a test in your method:

def call_one_or_the_other(x)
case x
when SomeClass
Role.something
when OtherClass
Organisation.anotherthing
end
end

Class.send(:method, *options) or

const_get(‘Class’).send(:method, *options)

possibly

const_get(‘Class’).send(:method, *options, &block) but i’m not sure
with this one.

Okay, misleading question.

What if I like to call the classes dynamically e.g.

def mymethod(class,method)
call(class,method,options)
end

?

Where call is the Ruby function I’m looking for.

greetings,

Both as strings or symbols?

def mymethod(class,method)
const_get(class).send(method)
end

Great const_get(‘Classname’).send is what I’m looking for. TIA!
