haml outputs errors into rendered page - _hamlout.format_script_false?

[jollyroger]

Hey guys,

i keep getting this haml-output in my view (yes, this is actually
printed out in the browser)

_hamlout.format_script_false_false_false_false_false_true_false
((haml_very_temp = haml_temp; haml_temp = nil; haml_very_temp));}

This is printed within a div which is rendered by this code:

- form_tag ({:action => "show"}, :id => 'checkout_next_step_form') do
= submit_tag '', :type => 'image', :src => get_img_prefix +
PATH_TO_CHECKOUT_NEXT_STEP_BUTTON, :class =>
'checkout_next_step_button mouseover_button', :id =>
'next_step_button'

This piece of code renders the following html:

<div id="shoppingcart_next_step">
<form method="post" id="checkout_next_step_form" action="/
checkouts/show"><div style="margin: 0pt; padding: 0pt; display:
inline;"><input type="hidden" value="mWhjyobUb7f/uRqWpuv8sNNfw5cU/
a5iMxfVT+r/THE=" name="authenticity_token"/></div>
<input type="image" value="" src="/images/de/checkout/
checkout_next_step_button.png" name="commit" id="next_step_button"
class="checkout_next_step_button mouseover_button"/>
</form>

_hamlout.format_script_false_false_false_false_false_true_false
((haml_very_temp = haml_temp; haml_temp = nil; haml_very_temp));}
</div>

How can this happen?
I don't see any obvious errors in the code above.
How could i debug this further?

In order to properly debug this, I'd need to see the entire Haml template. Could you put it up on gist?

Hi Nathan,

and sorry for the late reply.

The thing is, I had a major refactoring recently and since that, I
don't get this error anymore.

So => problem solved...:-)

P.S.:

I also believe that my markup wasn't the best (forms nested in
tables....), so it was probably more a problem with my code than
your's (although I'd still consider outputting the errors a bug)

I consider it a bug as well. I'd very much like to see a template that produces it, because I can't really do anything about it otherwise.

Nathan,

I got the same effect with this erroneous code:

%h1 My Header
= render :partial => 'form'}
%br

See that orphan }

Hope that helps. Regards

Christoph

Hmm... in the case of Ruby syntax errors, I'm afraid I can't really help. Since Haml compiles to Ruby code, and any Ruby code in the Haml template is literally included in the compiled template, it will always be possible to create malformed Ruby with odd effects such as this.
