未使用 FileField 上传 Django 文件(上传到=)

Django file not uploaded using FileField(upload to=)

我对 django 的概念及其功能很陌生 所以我遇到了一个项目,它可以很容易地帮助一个人使用 FileField Upload to 将文件上传到一个目录,但对我来说它不起作用,我尝试了不同的方式来修改它,但我仍然不确定我得到的错误。

所以有人请指导我

这是我的代码:

Models.py

class UploadedFiles(models.Model):
    files_to_upload = models.FileField(upload_to='uploaded_files/', default=None, validators=[validate_file])
    path = models.CharField(max_length=100)
    server = MultiSelectField(choices=server_list)

    SalesforceTicket = models.ForeignKey(SalesforceTicket, related_name="files", on_delete=models.CASCADE)

    def __str__(self):
        return str(self.SalesforceTicket)

forms.py

class FilesForm(forms.ModelForm):
    class Meta:
        model = UploadedFiles
        fields = ['files_to_upload', 'path', 'server']

    # called on validation of the form
    def clean(self):
        # run the standard clean method first
        cleaned_data = super(FilesForm, self).clean()
        files_to_upload = cleaned_data.get("files_to_upload")
        path = cleaned_data.get("path")
        server = cleaned_data.get("server")
        # print(files_to_upload)
        # print(path)
        # print(server)
        new_path = path.replace(':', '$', 1)
        # print(new_path)
        mode = 0o666
        for s in server:
            s = r'\' + s
            unc_path = os.path.join(s, new_path)
            print("hello"+unc_path)
            #unc_path = os.mkdir(unc_path, mode)
        isdir = os.path.isdir(unc_path)

        if isdir:
            print("ok")
        else:
            unc_path = os.mkdir(unc_path, mode)
        return cleaned_data

Views.py

def files(request):
    num_of_files = 1
    filled_multi_file_form = MultipleForm(request.GET)
    if filled_multi_file_form.is_valid():
        num_of_files = filled_multi_file_form.cleaned_data['num_of_files']

    FilesFormSet = formset_factory(FilesForm, extra=num_of_files)
    formset = FilesFormSet()

    if request.method == 'POST':
        filled_form = SnippetForm(request.POST, request.FILES)
       
        filled_formset = FilesFormSet(request.POST, request.FILES)
        if filled_form.is_valid() and filled_formset.is_valid():
                     print"hi"

在 settings.py 中,我包括 MEDIA_ROOT = 'C:\newform-16oct'

并在 html 中:enctype="multipart/form-data" method="POST"

。我在 google 上搜索时唯一显示的是这个,我的代码与 google 中的代码相同,不知道我是否无法识别错误。

所以在我迁移和 运行 这个之后,它没有给我任何错误,但是当我检查文件夹时它是空的

谁能帮帮我

编辑代码后出现错误: 由于文件未复制到 upload_files ,当我尝试将文件复制到另一个网络共享驱动器时它抛出错误,说 upload_files 中没有文件

因此,如果我尝试使用 django admin 添加,它会抛出错误

该文件夹将保持为空,因为您创建了一个生成新目录的脚本,但您从未要求将该文件保存在那里。

但是我认为你是在错误的位置解决问题。表单不需要处理那个。 Django 模型可以处理这个问题:您可以传递一个函数作为 upload_to=… parameter [Django-doc]:

的值
class UploadedFiles(models.Model):
    def <b>file_path</b>(self, filename):
        return f'uploaded_files/{self.server}/{self.path.replace(":","$", 1)}/{filename}'
        
    files_to_upload = models.FileField(
        <b>upload_to=file_path</b>,
        default=None,
        validators=[validate_file]
    )
    path = models.CharField(max_length=100)
    server = MultiSelectField(choices=server_list)

    SalesforceTicket = models.ForeignKey(
        SalesforceTicket,
        related_name='files',
        on_delete=models.CASCADE
    )

    def __str__(self):
        return str(self.SalesforceTicket)

或类似的东西。
