ruby on rails - How can I call methods within controller (RoR)?

Question

I am very new to RoR and I have played around the source code. But I have a problem that I already built a 'def A' for creating first CSV file, and 'def B' for creating second CSV file. Each 'def' has its own button, but I have the third button to create all CSVs (to produce output from first and second CSV files.)

What is the possible way to do it?

def first_csv
...
end

def second_csv
..
end

def all_csv
<< how to call get first and second csv >>
end

Thanks in advance,

Answer 1

It should be as simple as you imagine:

def all_csv
  first_csv
  second_csv
end
