Configuration¶
Here, we assume you already:
- Have registered an account on Selectel,
- Spent some money there,
- Created a couple of containers and got credentials for it.
if you haven’t yet, consider doing that right now.
A minimal installation¶
To begin using Selectel storage as your storage, you should configure your containers credentials:
SELECTEL_STORAGES = {
'default': {
'USERNAME': 'xxxx_user',
'PASSWORD': 'p455w0rd',
'CONTAINER': 'my-data',
},
'yet_another_storage': 'selectel://xxxx_user:p455w0rd2@another-container',
}
As you already guessed, the dictionary means you can create as much configurations
as you want. Here, we have two schemas: default and yet_another_storage.
You’re free to use any names for schema but strongly recommended to declare a schema with name ``default``.
Also, as you already guessed again, you can specify credentials either:
- As a dictionary with
USERNAME,PASSWORDorCONTAINERkeys, or - a URL-like string with schema
selectel://
Please see all available configuration options below.
Attention
Credentials in examples above are hardcoded. It really sucks, don’t do that in real life. Instead, you can store these variables in the environment and extract it out of there, for example, via awesome python-decouple package.
Using django-selectel-storage as a default backend¶
If you want to use the storage by default, consider adding to your settings.py:
DEFAULT_FILE_STORAGE = 'django_selectel_storage.storage.SelectelStorage'
in this case, the default schema will be implicitly used. Please make sure
you defined it before.
Storage initialization¶
If you want to explicitly instantiate a storage, you should write something like that:
# models.py
from django.db import models
class Post(models.Model):
photo = models.ImageField(storage=storage_instance)
Wondering, what storage_instance is? Well, it would be one of:
from django_selectel_storage.storage import SelectelStorage
storage_instance = SelectelStorage()
storage_instance = SelectelStorage('default')
storage_instance = SelectelStorage(storage='default')
Please pay attention: the last three lines of code do the same thing: creates
a SelectelStorage instance with using default schema. Of course, you
can choose any different schema (if you’ve defined it of course):
storage_instance = SelectelStorage('yet_another_storage')
storage_instance = SelectelStorage(storage='yet_another_storage')
We even create an instance via DSN (it’s useful somewhere in ./manage.py shell, please don’t do that in production):
storage_instance = SelectelStorage('selectel://user:password@container_name/')
storage_instance = SelectelStorage(storage='selectel://user:password@container_name/')
An interesting gotcha here: if you specify a DSN (a string begins with selectel://) as a first positional argument, it would
act like a dsn rather as storage=
