此代码可能会帮助：
# Add to your settings file
CONTENT_TYPES = ['image', 'video']
# 2.5MB - 2621440
# 5MB - 5242880
# 10MB - 10485760
# 20MB - 20971520
# 50MB - 5242880
# 100MB 104857600
# 250MB - 214958080
# 500MB - 429916160
MAX_UPLOAD_SIZE = "5242880"
#Add to a form containing a FileField and change the field names accordingly.
from django.template.defaultfilters import filesizeformat
from django.utils.translation import ugettext_lazy as _
from django.conf import settings
def clean_content(self):
content = self.cleaned_data['content']
content_type = content.content_type.split('/')[0]
if content_type in settings.CONTENT_TYPES:
if content._size > settings.MAX_UPLOAD_SIZE:
raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (filesizeformat(settings.MAX_UPLOAD_SIZE), filesizeformat(content._size)))

return content
你可以使用此代码段格式检查器。它的作用是
第一。在应用程序内创建一个名为formatChecker.py的文件，在该文件中，你的模型具有要接受某种文件类型的FileField。
这是你的formatChecker.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.
2.5MB - 2621440
5MB - 5242880
10MB - 10485760
20MB - 20971520
50MB - 5242880
100MB - 104857600
250MB - 214958080
500MB - 429916160
"""
def __init__(self, *args, **kwargs):
self.content_types = kwargs.pop("content_types", [])
self.max_upload_size = kwargs.pop("max_upload_size", 0)
super(ContentTypeRestrictedFileField, self).__init__(*args, **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 formatChecker import ContentTypeRestrictedFileField
然后，使用此“ ContentTypeRestrictedFileField”代替“ FileField”。
例：
class Stuff(models.Model):
title = models.CharField(max_length=245)
handout = ContentTypeRestrictedFileField(upload_to='uploads/', content_types=['video/x-msvideo', 'application/pdf', 'video/mp4', 'audio/mpeg', ],max_upload_size=5242880,blank=True, null=True)
你可以将“ max_upload_size”的值更改为所需的文件大小限制。你还可以将“ content_types”列表中的值更改为要接受的文件类型。
