While testing the Rails 2.2.0 release I soon knew I had a problem: I'm
relying on the fact that an ERB template is recompiled if the
modification time of the file has been updated.
I work on a multisite Rails app, which uses 'request.host' to do a
Site.find_by_domain and uses a before filter to call
'prepend_view_path("#{RAILS_ROOT}/themes/[EMAIL PROTECTED]/templates").
It's also possible to upload a new theme for a specific site via an
admin backend.
It's comparable to Shopify, but instead of using Liquid it relies on
Rails' templating mechanism.
The line of code that made this work is located here:
http://github.com/rails/rails/tree/v2.1.2/actionpack/lib/action_view/template_handlers/compilable.rb#L70,
but in rails-2.2.0 thing have been rewritten and the check is
unfortunately gone:
http://github.com/rails/rails/tree/v2.2.0/actionpack/lib/action_view/renderable.rb#L90.
Currently this means that I need to run this app in production with
'config.cache_classes = false' in order to upgrade to Rails 2.2.0,
which reloads all application code on every requests. That's going to
be slow. Another solution is restarting the whole app after changing
the theme for a single site.
Is there a way for me to reset the template cache manually after a
theme has been updated?
