HAML is indentation based , and the parser can be tricky.You don't need to use "- end" in Haml. Use indentation instead.In Haml,a block begins whenever the indentation is increased after a Ruby evaluation command. It ends when the indentation decreases.Sample if else block as follows.

- if condition
  = something
- else
  = something_else

A practical example 

- if current_user
  = link_to 'Logout', logout_path
- else
  = link_to 'Login', login_path

Edit : If you just want to use if condition then 

 - if current_user
  = link_to 'Logout', logout_path
