Ruby: How to call function before it is defined?

Question

In my seeds.rb file I would like to have the following structure:

# begin of variables initialization
groups = ...
# end of variables initializa         


        

Answer 1

Wrap your initial calls in a function and call that function at the end:

# begin of variables initialization
groups = ...
# end of variables initialization

def to_be_run_later
  check_data
  save_data_in_database
end

# functions go here
def check_data
  ...
end

def save_data_in_database
  ...
end

to_be_run_later
