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"

in settings.py , i included MEDIA_ROOT = 'C:\newform-16oct'

and in html :enctype="multipart/form-data" method="POST"

. Only thing that shows when i search on google is this , and my code is same as the one that is in google , don know whether am not able to identify error .

so after i migrate and run this , it is not throwing me any error , but when i check the folder it is empty

can anyone kindly help me

Error got after editing the code : since the file is not copied to upload_files , when i try to copy the file to another network shared drive it is throwing me error , saying there is no file inside upload_files

so if i try to add using django admin , it is thrwoing me below error

Answer 1

The folder will remain empty since you made a script that generates a new directory, but never do you ask to save that file there.

However I think you are solving the problem at the wrong location. The form does not need to handle that. A Django model can handle this: you can pass a function as value for the upload_to=… parameter [Django-doc]:

class UploadedFiles(models.Model):
    def file_path(self, filename):
        return f'uploaded_files/{self.server}/{self.path.replace(":","$", 1)}/{filename}'
        
    files_to_upload = models.FileField(
        upload_to=file_path,
        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)

or something similar.
