Question

在我提交具有图像字段的模型时，在Django上，保存模型时，在保存上传文件时会出现此错误

模型简单有一行

student(model):
    photo = models.ImageField(upload_to='/photos')

提交表单时会出现此错误

OSError(13, 'Permission denied')

在模型save（）方法中使用此点

/usr/lib/python2.7/site-packages/django/core/files/storage.py in _save
                fd = os.open(full_path, flags, 0o666)

引发错误的部件代码是

flags = (os.O_WRONLY | os.O_CREAT | os.O_EXCL |
                         getattr(os, 'O_BINARY', 0))
                # The current umask value is masked out by os.open!
fd = os.open(full_path, flags, 0o666)

在Django源代码中检查此行： https://github.com/django/django/blob/master/django/core/files/storage.py#L221

变量内容

e : OSError(13, 'Permission denied')
name : u'photos/10703514_652406348206730_7516458761930522613_n.jpg'

content : <ImageFieldFile: 10703514_652406348206730_7516458761930522613_n.jpg>
flags : 193

您认为这是一个许可问题，但即使是：

chmod -R 777 *

我得到了同样的错误，所以这不是权限问题，而是其他限制

的问题

/ var / www / pr5 / 是项目目录

用户和组是cherokee：cherokee用于其下的目录中的所有文件

chown -R cherokee:cherokee *

并且chmod也是777（应该是770）

我正在使用切诺基作为Web服务器来提供静态和媒体文件使用此命令在套接字上运行

/usr/bin/python2 /var/www/pr5/manage.py runfcgi method=threaded socket=/tmp/djangoche.socket daemonize=False protocol=scgi

settings.py

FILE_UPLOAD_PERMISSIONS = 770
FILE_UPLOAD_DIRECTORY_PERMISSIONS =770


MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR + '/mediafolder/'
STATIC_URL = '/static/'
STATIC_ROOT = BASE_DIR + '/staticfolder/'
STATICFILES_DIRS = (
BASE_DIR + STATIC_URL,
)

我搜索了其他问题，但没有解决这个问题。

表单是表格有效的经典的简单保存实例

class NewStudent(View):

    student_form = modelform_factory(Student,exclude=())

    def get(self, request,pk=None):

        stu=self.student_form() 
        return render(request,'school/student_new.html',{'form1': stu)
    def post(self, request):

        stu=self.student_form(request.POST,request.FILES)

        if stu.is_valid() :
            studentvar=stu.save()

            return redirect(to='student_detail',pk=studentvar.pk)

        return render(request,'school/student_new.html',{'form1': stu)

Answer 1

使用在tmp目录中创建的套接字执行导致问题

我通过移动套接字文件解决了这个问题：

从/tmp/djangoche.socket到/var/www/pr5/server.socket

WSGI和uWSGI配置案例出现问题

如果没有修复，你也可以尝试这个

（仅适用于cherokee服务器）取消选中Cherokee管理中的“检查文件”，以获取处理WSGI（或类似）的虚拟服务器，这适用于基于文件的脚本，如php，它会导致很多问题案件。此选项位于常见CGI选项部分

处理程序

Secondely（可选与第一个修复一起使用），添加到您的WSGI.py文件中：

导入系统 sys.path.append（ '/路径/要/项目'） sys.path.append（ '/路径/到/项目/项目名称'）

OSError [Errno 13]文件上载权限被拒绝
