I have a haml like above and i am using it in a Sinatra application. When i run my app

haml :problem_haml

Every single ruby command works perfectly, but haml does not render anything. Not even a single line, yet every ruby command starts with "-" works absolutely perfect? What could be the cause? Please do not answer "because hidden class hides everything", it is not about css hiding, literally not even a single byte returns from server.

Edit:

I said the application is a sinatra application before, but it is actually a Padrino application. While padrino is only a few sinatra applications that run inside a main sinatra application and more people knows sinatra, i said sinatra to make the question simpler.

Also here is the code that calls haml,

def get3DSecure(ccname,price,skul,ccno,cvc)
    puts "#############################################"
    puts "get3DSecure function called"
    puts "#############################################"
    @ccname = ccname
    @price = price.to_s + "00"
    @skul = skul
    @ccno = ccno
    @cvc = cvc
    session[:name] = ccname
    session[:xmltosend] = makeXmlFor3D
    session[:sipbil] = UUIDTools::UUID.random_create.to_s.delete!("-")
    session[:sesbil] = UUIDTools::UUID.random_create.to_s.delete!("-")
    session[:skul] = skul
    session[:price] = price
    session[:ccno] = ccno
    session[:cvc] = cvc
    puts "#############################################"
    puts "get3DSecure function near end, render starts"
    puts "#############################################"
    render :adsecure,:layout=>:main
  end

It also writes the puts commands to console without any problems.

The HTML that will be generated by the Haml here will not show up in the browser. You say “not even a single byte returns from server” – are you sure? If that is the case then this likely isn’t a Haml issue. Can you see the HTML if you view source in your browser. Note that using `puts` will write to stdout (likely to the terminal), _not_ to your HTML page. — matt, Sep 20 '12 at 22:23

Your code works for me, although first I got:

WARN: tilt autoloading 'haml' in a non thread-safe way; explicit require 'haml' suggested.

Because I forgot to add:

require "haml"

At the beginning of my code. Could it be your problem?

I have find out that render or haml methods does not do return. So if you are in middle of your function, your should do

return haml :problem_haml

It fixes the problem.

You may check if your form is submitted, using chrome developer tools, firebug or something like (check POST), and if it is, as there is a post request you need to handle the response, just a guess :)

pay attention while you are using puts inside haml/slim/erb templates, this because haml has it's own puts method: http://haml.info/docs/yardoc/Haml/Exec/Generic.html#puts-instance_method

so, since you are using padrino, replace every puts with: logger.debug
