I’m having an issue with HAML where it is attempting to write to a read-only filesystem (on a Heroku-deployed app).

I can only write to /tmp and /log. How can I configure HAML to write files to the /tmp directory?

Thanks!

    Like Mark commented, I think you mean SASS, not Haml. Here’s how to use git commit-hooks to precompile your SASS before deploying to heroku.

    EDIT: After full error was posted

    Change

    = stylesheet_link_tag "reset", "application", "grid", :cache => "base"

    to

    = stylesheet_link_tag "reset", "application", "grid"

    The caching isn’t HAML, it’s RAILS, and it’s doing this on first read.
