Unable to locate file main.scss while rendering tag 'sass_src' in template index.html about django-sass-processor

[jdewanwala]

That's great! It works! Thank you, both Jacob and Andreas! Closing the issue.

For the benefit of others, here are the final folder structure and settings:

1. Folder Structure

2. Settings.py

STATIC_URL = '/static/'

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'scss'),
]

STATICFILES_FINDERS = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'sass_processor.finders.CssFinder',
]

SASS_PROCESSOR_ROOT = os.path.join(BASE_DIR,"temp_files")

Rest of the settings are same as above.

Personally I wouldn't recommend using the static folder as your SCSS folder as it will be the place where compiled files and more end up.

After having looked a bit deeper at your configuration now that I'm on my PC, I can see that you probably don't have the scss folder setup in STATICFILES_DIRS. Set it up like this:

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'scss'),
]

The finders in STATICFILES_FINDERS are setup to use STATICFILES_DIRS but you don't seem to have that setup so it does not know where to look. This setup tells it that it can look for SCSS files in sassy/scss.

And you could remove the following configuration from your settings as you've set these to the default values:

SASS_PROCESSOR_ROOT = STATIC_ROOT 

SASS_PRECISION = 8

SASS_PROCESSOR_ROOT is simply the location of the compiled SCSS file and not the place it'll look for SCSS files.

If you don't use STATIC_ROOT, then you must set SASS_PROCESSOR_ROOT.
Point it onto a directory where you keep temporary files. Sass-Processor writes the compiled CSS into that directory. From there, Django delivers that CSS file.

[AndreasBackx]

Please verify that BASE_DIR actually points to the directory sassy and not its parent.

Also please use proper GitHub flavoured Markdown, I've fixed it for now.

Thanks for the quick response Andreas. This is what the BASE_DIR refers to:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

where file is settings.py with 'standard folder' structure:

print(BASE_DIR) outputs:
../../django/sassy

Hi Andreas,

So I made the changes you recommended and now get the following error:

TypeError at /
stat: path should be string, bytes, os.PathLike or integer, not NoneType

1. This is the change I made to the settings.py file:

STATIC_URL = '/static/'

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'scss'),
]

STATICFILES_FINDERS = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'sass_processor.finders.CssFinder',
]

I also removed:

# SASS_PROCESSOR_ROOT = STATIC_ROOT 
# SASS_PRECISION = 8

2. I moved the scss files into their own folder under the BASE_DIR folder:

3. I am still referencing the scss in the .html file as:
<link href="{% sass_src 'main.scss' %}" rel="stylesheet" type="text/css" />

You must add sassy to your INSTALLED_APPS.
