Django-Bower + Foundation 5 + SASS, How to configu

问题:

I'm in the process of testing out a SASS implementation of Foundation 5 using Django-Bower. I'm new to the idea of Bower and am having a bit of confusion as to how to get this setup working properly.

I have django-bower installed and configured to run properly. After I added foundation to the bower apps config and ran manage.py bower_install I can see that the foundation files have indeed been installed properly. I can also use the static tag to load the JS into a template without an issue, so I feel like I'm about halfway there.

My issue is in regards to how to actually use the foundation files that bower installed with my custom SASS files, and the best way to compile those SASS files into CSS. I know that I'm supposed to be able to include foundation into my SASS with @include "foundation" but I'm lost as to how to get the SASS file to "see" the foundation files in components/bower_components/foundation/sass and how to set up a compile to put the css into the correct static file.

UPDATE: PyCharm has an option to watch sass files and compile them, so I now have an option for compiling the files, but when I attempt to import foundation i get error blog3.sass (Line 1: File to import not found or unreadable: foundation.

For reference, here's my file structure:

SOLUTION WITHOUT PYCHARM WATCHER

1. Not using pycharm watcher.
2. django-compressor to compile scss files including compass.
3. django-bower

This is an example of "how to compile scss files" with django-compressor:

appName/static/scss/app.scss:

@import "../../../components/bower_components/foundation/scss/foundation";
@import "compass";

/* other stuff*/

settings.py:

STATICFILES_FINDERS = (
    .....
    'compressor.finders.CompressorFinder',

)

COMPRESS_PRECOMPILERS = (
    ('text/x-sass', 'sass --compass "{infile}" "{outfile}"'),
    ('text/x-scss', 'sass --scss --compass "{infile}" "{outfile}"'),
)

COMPRESS_URL = '/static/'

template.html:

{% load static %}
{% load compress %}

<head>
    {% compress css %}
        <link href="{% static 'scss/app.scss' %}" media="screen, projection" rel="stylesheet" type="text/x-scss" />
    {% endcompress %}

</head>

Hope this help you.

EDIT

Maybe this is a better config to use @import without relatives paths. -I arg:

PROJECT_PATH = os.path.abspath(os.path.dirname(__file__))
BOWER_COMPONENTS_ROOT = os.path.join(PROJECT_PATH, "../components/")
COMPRESS_PRECOMPILERS = (
        ('text/x-sass', 'sass --compass "{infile}" "{outfile}"'),
        ('text/x-scss', 'sass --scss --compass -I "%s/bower_components/foundation/scss" "{infile}" "{outfile}"' % BOWER_COMPONENTS_ROOT),
    )

Now app.scss:

@import "foundation";
@import "compass";

USING PYCHARM WATCHER

Lately I'm appreciating pycharm watcher

1. Install django-bower
2. Add a SCSS Watcher from pycharm preferences

3. In the edit of watcher, into 'Arguments' field I set:

   --compass -I "/$ProjectFileDir$/components/bower_components/foundation/scss" --no-cache --update $FileName$:$FileNameWithoutExtension$.css

So, in the scss file:

@import "foundation";
@import "compass";

packages:

1. django-pipeline
2. django-bower

How to compile with django-pipeline:

application.scss:

@import "../../../components/bower_components/foundation/scss/foundation";

settings.py:

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'pipeline',
    'djangobower',
)

BOWER_COMPONENTS_ROOT = os.path.join(BASE_DIR, 'components')

STATICFILES_FINDERS = (
    .....
    'djangobower.finders.BowerFinder',  # just for bower components

)

PIPELINE_CSS = {
    'application': {
        'source_filenames': (
            'css/application.scss',
        ),
        'output_filename': 'css/application.css',
        'extra_context': {
            'media': 'screen,projection',
        },
    },
}

PIPELINE_COMPILERS = (
    'pipeline.compilers.sass.SASSCompiler',
)

Then in template:

{% load compressed %}
{% compressed_css 'application' %}

This will compile on developemnt and on collectstatic will compile and compress
