Synopsis

Small application that simplifies naming of uploaded files. License is MIT.

Installation

You can get dj-upload-to release version from pypi with pip:

$ pip install dj-upload-to

or development one from github:

$ pip install -e git+https://github.com/marazmiki/dj-upload-to#egg=dj-upload-url

You’re not need include it into your INSTALLED_APPS

Usage

Assumes you have model:

from django.db import models
from dj_upload_to import UploadTo

upload_to = UploadTo()

class Model(models.Model):
    file = models.ImageField(upload_to=upload_to)

As you see, UploadTo generates callable object (with __call__ methodfor passing into upload_to attribute of FileField (see django upload_to docs for details)

When you save model with image originally named myphoto.JPG, file

will be saved with name such as:

model/ab/cd/abcdabcd-0123-4567-8901-234567890ab.jpg

where:

  • model is prefix automatically generated from model class. You can override it

  • ab is the first 2 char segment of filename

  • cd is the second 2 char segment of filename

  • abcdabcd-0123-4567-8901-234567890ab autogenerated with uuid filename

  • .jpg is a lower cased extension taken from original file

Customize

You can customize behavior of UploadTo with options in constructor:

  • prefix: prefix of filename. Default is dj_upload_to.not_provided. If None, prefix will be missed. If not explicitly set, will be generated automatically based on model class name

  • num_seg: number of parts of segmentation. Default is 2

  • seg_size: length of segment in chars. Default is 2

  • save_name: use original name without autogeneration. Default is False

There are some examples:

>>> model_instance = Model()

>>> # Disable prefix
>>> UploadTo(prefix=None)(model_instance, 'file.jpg')
'c0/17/c01745b4-e70b-4dd8-a5f7-76fec32fcb83.jpg'

>>> # Explicitly given prefix
>>> UploadTo(prefix='my_files')(model_instance, 'file.jpg')
u'my_files/d9/a4/d9a4ef25-11b0-41bb-a543-baaac6553024.jpg'

>>> # Four segment and automatically generated prefix
>>> UploadTo(num_seg=4)(model_instance, 'file.jpg')
u'model/36/52/99/f6/365299f6-8dc5-4ca2-848d-965f002a9b72.jpg'

>>> # Segment length is 4 chars
>>> UploadTo(seg_size=4)(model_instance, 'file.jpg')
u'model/3142/f2ef/3142f2ef-2680-4a99-82fc-3c8d9d3179dc.jpg'

>>> # Save original filename
>>> UploadTo(save_name=True)(model_instance, 'file.jpg')
u'model/file.jpg'

>>> # Save original filename without prefix
>>> UploadTo(save_name=True, prefix=None)(model_instance, 'file.jpg')
u'file.jpg'
