Collectstatic on Steroids
Project description
The fast collectstatic for Django projects with S3 as storage backend.
Running Django’s collectstatic command can become really slow as more and more files are added to a project, especially if heavy libraries such as jQuery UI are included in the source. This is a custom management command that compares the md5 sum of files with S3 and completely ignores modified_time. The results of the hash lookups are cached locally using your default Django cache. This can make deploying much faster!
Installation
Install the app using pip:
$ pip install Collectfast
Make sure you have this in your settings file and add 'collectfast' to your INSTALLED_APPS:
STATICFILES_STORAGE = "storages.backends.s3boto.S3BotoStorage"
AWS_PRELOAD_METADATA = True
INSTALLED_APPS = (
# …
'collectfast',
)For Django 1.7+, 'collectfast' should come before 'django.contrib.staticfiles'. For Django versions below 1.7, it should come after 'django.contrib.staticfiles'. Please note, that failure to do so will cause Django to use django.contrib.staticfiles’s collectstatic.
Note: preload_metadata of the storage class will be overwritten even if AWS_PRELOAD_METADATA is not set to True see #30
Setup Dedicated Cache Backend
It’s recommended to setup a dedicated cache backend for Collectfast. Every time Collectfast does not find a lookup for a file in the cache it will trigger a lookup to the storage backend, so it’s recommended to have a fairly high TIMEOUT setting.
Set up your dedicated cache in settings.py with the COLLECTFAST_CACHE setting:
CACHES = {
'default': {
# Your default cache
},
'collectfast': {
# Your dedicated Collectfast cache
}
}
COLLECTFAST_CACHE = 'collectfast'By default Collectfast will use the default cache.
Note: Collectfast will never clean the cache of obsolete files. To clean out the entire cache, use cache.clear(). Read more about Django’s cache framework.
Usage
Collectfast overrides Django’s builtin collectstatic command so just run python manage.py collectstatic as normal. You can disable collectfast by using the --ignore-etag option.
You can also disable collectfast by setting COLLECTFAST_ENABLED = False in your settings file. This is useful when using a local file storage backend for development.
