Beforehand sorry for my English, I’m from Russia.

I have 2 modules:

module SendMail  
def self.send\_mail(hash)  
# some code  
end  
end

module ActionMailer  
def quoted\_printable(text, charset)  
# some code  
end  
end

Please say me, is there any way to have access to method  
“quoted\_printable” of module ActionMailer from method send\_mail of  
module SendMail. It would be good, if I pass using Classes in this  
situation, because I want to divide  
namespaces correctly.

Nikita, quoted\_printable is an instance method. So you need to have an  
instance of a class which includes the ActionMailer module. If you  
have such an instance, you can call its quoted\_printable method.

If you want the object to be the SendMail module itself then extend  
SendMail with ActionMailer:

module ActionMailer  
def quoted\_printable(text, charset)  
# some code  
end  
end

module SendMail  
extend ActionMailer  
def self.send\_mail(hash)  
# some code  
quoted\_printable(…)  
end  
end
