我最近一直在问这个问题。
我创建了我的上传表单
模型.py
from django.db import models
from app.extra import ContentTypeRestrictedFileField
class upload(models.Model):
""" upload """
name = models.CharField(max_length=100)
description = models.CharField(max_length=250)
file = ContentTypeRestrictedFileField(
upload_to='/media/videos,'
content_types=['video/avi', 'video/mp4', 'video/3gp', 'video/wmp', 'video/flv', 'video/mov'],
max_upload_size=104857600
)
created = models.DateTimeField('created', auto_now_add=True)
modified = models.DateTimeField('modified', auto_now=True)
def __unicode__(self):
return self.name
表格.py
from django.db.models import FileField
from django.forms import forms
from django.template.defaultfilters import filesizeformat
from django.utils.translation import ugettext_lazy as _
class ContentTypeRestrictedFileField(FileField):
"""
Same as FileField, but you can specify:
* content_types - list containing allowed content_types. Example: ['application/pdf', 'image/jpeg']
* max_upload_size - a number indicating the maximum file size allowed for upload.

5MB - 5242880
10MB - 10485760
20MB - 20971520
50MB - 5242880
100MB 104857600

def __init__(self, content_types=None,max_upload_size=104857600, **kwargs):
self.content_types = kwargs.pop('video/avi', 'video/mp4', 'video/3gp', 'video/wmp', 'video/flv', 'video/mov')
self.max_upload_size = max_upload_size
super(ContentTypeRestrictedFileField, self).__init__(**kwargs)
def clean(self, *args, **kwargs):
data = super(ContentTypeRestrictedFileField, self).clean(*args, **kwargs)
file = data.file
try:
content_type = file.content_type
if content_type in self.content_types:
if file._size > self.max_upload_size:
raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (filesizeformat(self.max_upload_size), filesizeformat(file._size)))
else:
raise forms.ValidationError(_('Filetype not supported.'))
except AttributeError:
pass
return data
from south.modelsinspector import add_introspection_rules
add_introspection_rules([], ["^app\.extra\.ContentTypeRestrictedFileField"])
并添加这一行是settings.py
FILE_UPLOAD_MAX_MEMORY_SIZE = 157286400 # 157286400 bytes = 150 MB
但是有一个我没有看到的问题,一个 djangosnippets 用户说
If you're ok with letting people use up all your bandwidth for uploading 1GB
files to your servers just to delete them as soon as the upload finishes,
sure it's a great solution.
看到这个问题。这个问题是关于asp.net的,我用的是django,那么在你上传视频之前如何在django中检测视频的文件大小
