Question

I get a bool value as a parameter and assign it to a variable

@package = params[:package]

Now, I have a method which should return a string based on the value of package. The method looks like this:

def get_description(package)
    if package == 1
      "foo"
    elsif package == 2
      "bar"
    end
  end

In another method, I try to get the @description by:

@description = get_description(@package)

The problem is, the string is not displayed. The @description variable stays empty. Maybe I’m too stupid to see the bug?

If you want you can use your code changing the value of package to integer:

def get_description(package)
  package = package.to_i
  if package == 1
    "foo"
  elsif package == 2
    "bar"
  end
end

Or using a case statement:

def get_description(package)
  case package.to_i
  when 1
    "foo"
  when 2
    "bar"
  end
end
