Django文件上传大小限制
我在Django应用中有一个表单,用户可以在其中上传文件。
如何设置上传文件大小的限制,以便如果用户上传的文件大于我的限制,则该表格将无效并且会引发错误?

此代码可能会帮助:
# Add to your settings fileCONTENT_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)))
else:
raise forms.ValidationError(_('File type is not supported'))
return content
