Question

i would play a bit with Ruby.

Now i have a little problem, which i cannot solve.

The code:

@href = "http://localhost:3000"

def link(title, href)

  if href.nil?
    href = @href
  else
    href = href
  end

  output = "<a href=\"#{href}\">"
  output << "#{title}"
  output << "</a>"

  puts output

end

alias link_to link

link_to("Google","")

Whats the problem in my code?
I want set a default value for the href,if it is nil.

Answer 1

The problem is here

>> "".nil?
=> false

You should use .nil? or .empty? as the condition.

>> "".empty?
=> true
