Django provides convenient ways to access the default storage class:
A dictionary-like object that allows retrieving a storage instance using
its alias as defined by STORAGES.
storages has an attribute backends, which defaults to the raw value
provided in STORAGES.
Additionally, storages provides a create_storage() method that
accepts the dictionary used in STORAGES for a backend, and
returns a storage instance based on that backend definition. This may be
useful for third-party packages needing to instantiate storages in tests:
>>> from django.core.files.storage import storages
>>> storages.backends
{'default': {'BACKEND': 'django.core.files.storage.FileSystemStorage'},
'staticfiles': {'BACKEND': 'django.contrib.staticfiles.storage.StaticFilesStorage'},
'custom': {'BACKEND': 'package.storage.CustomStorage'}}
>>> storage_instance = storages.create_storage({"BACKEND": "package.storage.CustomStorage"})
DefaultStorage provides
lazy access to the default storage system as defined by default key in
STORAGES. DefaultStorage uses
storages internally.
default_storage is an instance of the
DefaultStorage.
FileSystemStorage¶The FileSystemStorage class implements
basic file storage on a local filesystem. It inherits from
Storage and provides implementations
for all the public methods thereof.
Catatan
Metode FileSystemStorage.delete() tidak akan memunculkan sebuah pengecualian jika nama diberikan tidak ada.
Absolute path to the directory that will hold the files.
Defaults to the value of your MEDIA_ROOT setting.
URL yang melayani berkas-berkas disimppan pada tempat ini. Awalan pada nilai dari pengaturan MEDIA_URL anda.
The file system permissions that the file will receive when it is
saved. Defaults to FILE_UPLOAD_PERMISSIONS.
Perizinan sistem berkas dimana direktori akan menerima ketika itu disimpan. Awalan pada FILE_UPLOAD_DIRECTORY_PERMISSIONS.
Flag to control allowing saving a new file over an existing one.
Defaults to False.
Returns a datetime of the system's ctime, i.e.
os.path.getctime(). On some systems (like Unix), this is the
time of the last metadata change, and on others (like Windows), it's
the creation time of the file.
InMemoryStorage class¶The InMemoryStorage class implements
a memory-based file storage. It has no persistence, but can be useful for
speeding up tests by avoiding disk access.
Absolute path to the directory name assigned to files. Defaults to the
value of your MEDIA_ROOT setting.
URL yang melayani berkas-berkas disimppan pada tempat ini. Awalan pada nilai dari pengaturan MEDIA_URL anda.
The file system permissions assigned to files, provided for
compatibility with FileSystemStorage. Defaults to
FILE_UPLOAD_PERMISSIONS.
The file system permissions assigned to directories, provided for
compatibility with FileSystemStorage. Defaults to
FILE_UPLOAD_DIRECTORY_PERMISSIONS.
Storage¶The Storage class provides a
standardized API for storing files, along with a set of default
behaviors that all other storage systems can inherit or override
as necessary.
Catatan
When methods return naive datetime objects, the effective timezone
used will be the current value of os.environ['TZ']; note that this
is usually set from Django's TIME_ZONE.
Deletes the file referenced by name. If deletion is not supported
on the target storage system this will raise NotImplementedError
instead.
Returns True if a file referenced by the given name already exists
in the storage system.
Mengembalikan sebuah datetime dari waktu akses terakhir dari berkas. Untuk sistem penyimpanan tidak dapat mengembalikan ke waktu akses terakhir ini akan memunculkan NotImplementedError.
Jika USE_TZ adalah True, mengembalikan sebuah kewaspadaan datetime, sebaliknya mengembalikan datetime tidak dibuat-buat dalam zona waktu lokal.
Returns an alternative filename based on the file_root and
file_ext parameters, an underscore plus a random 7 character
alphanumeric string is appended to the filename before the extension.
Mengembalikan sebuah nama berkas berdasarkan pada parameter name yang bebas dan tersedia untuk isi baru untuk ditulis pada sasaran sistem penyimpanan.
The length of the filename will not exceed max_length, if provided.
If a free unique filename cannot be found, a
SuspiciousFileOperation exception will be raised.
If a file with name already exists, get_alternative_name() is
called to obtain an alternative name.
Returns a datetime of the creation time of the file.
For storage systems unable to return the creation time this will raise
NotImplementedError.
Jika USE_TZ adalah True, mengembalikan sebuah kewaspadaan datetime, sebaliknya mengembalikan datetime tidak dibuat-buat dalam zona waktu lokal.
Returns a datetime of the last modified time of the
file. For storage systems unable to return the last modified time this
will raise NotImplementedError.
Jika USE_TZ adalah True, mengembalikan sebuah kewaspadaan datetime, sebaliknya mengembalikan datetime tidak dibuat-buat dalam zona waktu lokal.
Returns a filename based on the name parameter that's suitable
for use on the target storage system.
Mensahkan filename dengan memanggil get_valid_name() dan mengembalikan sebuah nama berkas dilewatkan ke metedo save().
The filename argument may include a path as returned by
FileField.upload_to.
In that case, the path won't be passed to get_valid_name() but
will be prepended back to the resulting name.
Penerapan awal menggunakan operasi os.path. Kesampingkan cara ini jika itu tidak sesuai untuk penyimpanan anda.
Lists the contents of the specified path, returning a 2-tuple of lists;
the first item being directories, the second item being files. For
storage systems that aren't able to provide such a listing, this will
raise a NotImplementedError instead.
Opens the file given by name. Note that although the returned file
is guaranteed to be a File object, it might actually be some
subclass. In the case of remote file storage this means that
reading/writing could be quite slow, so be warned.
The local filesystem path where the file can be opened using Python's
standard open(). For storage systems that aren't accessible from
the local filesystem, this will raise NotImplementedError instead.
Saves a new file using the storage system, preferably with the name
specified. If there already exists a file with this name name, the
storage system may modify the filename as necessary to get a unique
name. The actual name of the stored file will be returned.
Argumen max_length dilewatkan bersama pada get_available_name().
The content argument must be an instance of
django.core.files.File or a file-like object that can be
wrapped in File.
