Django max_upload_size 被忽略

Question

我有这段代码，但由于某种原因，文件大小被忽略了，即使我在 formatChecker.py 中直接将其设置为 ('max_upload_size', 5242880)，在上传完成后，该值似乎也被忽略了。

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:
        * 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.

    def __init__(self, *args, **kwargs):
        self.content_types = kwargs.pop('content_types', [])

        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 > int(MAX_UPLOAD_SIZE):
                    raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (
                        filesizeformat(MAX_UPLOAD_SIZE), filesizeformat(file._size)))
            else:
                raise forms.ValidationError(_('Filetype not supported.'))
        except AttributeError:
            pass
        return data

models.py

...
class Post(models.Model):
    postattachment = ContentTypeRestrictedFileField(
      blank=True,
      null=True,
      upload_to=get_file_path_user_uploads,
      content_types=['application/pdf',
                     'application/zip',
                     'application/x-rar-compressed',
                     'application/x-tar',
                     'image/gif',
                     'image/jpeg',
                     'image/png',
                     'image/svg+xml',
                     ]
     )
...

知道为什么会出现这个问题吗？ 我是不是在这里忘记了什么？

Answer 1

在setting.py中添加MAX_UPLOAD_SIZE = "5242880"

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，弹出两个key，所以不存在

    def __init__(self, *args, **kwargs):
       self.content_types = kwargs.pop('content_types', [])
       self.max_upload_size = kwargs.pop('max_upload_size',[])

所以删除这些行

self.content_types = kwargs.pop('content_types', [])
self.max_upload_size = kwargs.pop('max_upload_size', [])
