我有一个名为 ClassFile 的模型,它采用 FileField(文档):
class ClassFile(models.Model):
timestamp = models.DateTimeField(auto_now_add=True, editable=False)
document = models.FileField(upload_to="classFiles/%Y/%m/%d/")
description = models.TextField('File description', max_length=500)
shown = models.BooleanField('Allow Students to view this', default=True)
course = models.ForeignKey(Course, related_name='files', editable=False)
uploader = models.ForeignKey(User, related_name='class_files_uploaded')
提交文件上传表单后尝试保存以下 ClassFile 实例失败,因为 request.FILES['file'] 显然不存在:
f = ClassFile(
document = request.FILES['file'],
description = form.cleaned_data['description'],
shown = form.cleaned_data['shown'],
course = course,
uploader = request.user,
)
f.save()
我想知道我是否以正确的方式保存了这个对象。request.FILES['file'] 的类型是否正确?谢谢你。
