我有这段代码,但是出于某种原因,即使我在formatChecker.py上直接将其设置为('max_upload_size',5242880),文件大小也被忽略了。 >
settings.py
MAX_UPLOAD_SIZE = "5242880"
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 _
from myproject.settings import MAX_UPLOAD_SIZE
class ContentTypeRestrictedFileField(FileField):
"""
Same as FileField, but you can specify:

知道为什么会出现此问题吗? 我在这里忘了东西吗?
预先感谢
答案 0 :(得分:1)
在MAX_UPLOAD_SIZE = "5242880"
中添加setting.py
然后在视图文件中
from django.conf import settings
file._size > settings.MAX_UPLOAD_SIZE
或file._size > int(settings.MAX_UPLOAD_SIZE)
在init方法中,它会弹出两个键,因此它不存在
def __init__(self, *args, **kwargs):
self.content_types = kwargs.pop('content_types', [])
self.max_upload_size = kwargs.pop('max_upload_size',[])
因此删除这些行
self.content_types = kwargs.pop('content_types', [])
self.max_upload_size = kwargs.pop('max_upload_size', [])
