How to livereload Django templates?

[Nikolay Georgiev]

Do you know some tips or concrete steps on how to livereload Django templates?

Livereloading means that if I change the HTML Template, CSS or JS files that these files will be automatically reloaded in the browser, without me having to refresh the page manually. This leads to increased productivity. http://livereload.com/

Thank you very much!

Hi Nikolay,

this mailing lists is about the development of Django itself; you might wanna ask that on django-users

Hi Florian,

after trying to add livereload I came to the conclusion that it should be implemented in Django itself. I managed to add CSS livereload with Cross Browser CSS Injection: http://css-tricks.com/cross-browser-css-injection/, but HTML files cannot be reloaded without knowing how Django templating works. That's why I help is needed not from the user, but from the Django developers.

The easiest implementation would be: If a Django template (HTML) changes, refresh the browser.

How can this be implemented in Django itself?

Greetings,

Nikolay

Hi Nikolay,

You could implement such a feature as a third party app by connecting a receiver to the template_rendered signal.

I suggest you take a look at how django-debug-toolbar tracks which template were used.

Please move forward discussion to django-users since, as pointed out by Florian, it's out of django-developpers scope.

Thanks,
Simon

To do a live reload the tool need to know when the template in filesystem is updated, then using template_rendered will not help because need to make a request and the live reload is to automatically do that request when some file is updated.

I don't know if will be possible to add that to django itself, but I think that using some tool like watchdog [1] could help doing that.

Other idea is to override the development server command to monitor the changes to templates files.

I found a very simple solution using Grunt and a browser extension:
