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

You can pass a hash of parameters to the Haml method using the :locals key:

get '/' do
    haml :index, :locals => {:some_object => some_object}
end

This way the Ruby code in your Haml file can access some_object and render whatever content is in there, call methods etc.
