How to use Django's filesizeformat
- by Scott LaPlant
I have a small app I'm working on where I'm trying to use Django's built in filesizeformat. Currently, the format looks like this: {{ value|filesizeformat }} I understand I need to define this in my view.py file but, I can't seem to figure out how to do that. I've tried to use the syntax below:
def filesizeformat(bytes):
"""
Formats the value like a 'human-readable' file size (i.e. 13 KB, 4.1 MB,
102 bytes, etc).
"""
try:
bytes = float(bytes)
except (TypeError,ValueError,UnicodeDecodeError):
return u"0 bytes"
if bytes < 1024:
return ungettext("%(size)d byte", "%(size)d bytes", bytes) % {'size': bytes}
if bytes < 1024 * 1024:
return ugettext("%.1f KB") % (bytes / 1024)
if bytes < 1024 * 1024 * 1024:
return ugettext("%.1f MB") % (bytes / (1024 * 1024))
return ugettext("%.1f GB") % (bytes / (1024 * 1024 * 1024))
filesizeformat.is_safe = True
I've then replaced 'value' with 'bytes' in the template but, this does not seem to work. Any suggestions?
