How to pass an argument when calling a view file?

Question

I wrote a webform using Sinatra and Haml that will be used to call a Ruby script.

Everything seems fine except for one thing: I need to pass an argument to a Haml view f

Answer 1

Haml supports passing variables as locals. With Sinatra, you can send these locals like so:

haml :fail, :locals => {:vm_name => name}

and in the view, reference the variable using locals[:vm_name] or simply vm_name.
