hello, i got this error:

Haml::Error in Projects#show

Showing app/views/projects/parts/_app_item.html.haml where line #24 raised:

haml_tag outputs directly to the Haml template.
Disregard its return value and use the - operator,
or use capture_haml to get the value as a String.

Extracted source (around line #24):
