Is it possible to force generation of assets with Rails Asset Pipeline?

Question

Is there a way to force regeneration of assets every request when using the Rails 3.1 Asset Pipeline?

I am having problems getting the system to pick up changes to files when using Less (less-rails) with a series of partials and mixin files. If I could just force the system to generation on each request I would be much more productive.

To force a complete regeneration of all assets use:

rake assets:clobber assets:precompile

Very handy when asset_sync isn't playing fair with you...

I know this may not help you, but hopefully it will make it easier for someone else to find the answer.

You can reset the assets cache with

rake tmp:cache:clear

Autmoatization would be preferable. – Niels Abildgaard Jun 04 '14 at 13:22
You'd have to put this command in a script set to run at whatever point you want to automate it into. I can't provide an automation suggestion without more information. – Mike Lyons Jun 02 '17 at 07:04

You have to run your server in the development environment. I think you can also use something like config.cache_classes = false in your current environment's config file.

Was doing that, but turns out my issue was caused by slightly different problem. Thanks. – Toby Hede Oct 07 '11 at 04:37

I worked it out.

The master.less file (as in the main less file that coordinates the other include files) needed to have the pipeline directives added to it.

So in my case, application.css contains:

/*
 *= require html5reset-1.6.1
 *= require master
*/

And master.css.less contains:

/*
 *= depend_on mixins
*/
@import "mixins";

You should emphasize that the important part is "depend_on" :) – Niels Abildgaard Jun 04 '14 at 13:24
What exactly does this do? Does it invalidate the cache on every request? What is happening in asset pipeline to accomplish the result you want? – Mike Lyons Apr 04 '19 at 13:09
