У меня есть следующий код:

urls.py:

 urlpatterns = [
    ...
    url(r'^upload_file', FileFieldFormView.as_view(), name='upload_file'),
    url(r'^success', lambda request: HttpResponse('Hello World!'), name='hello_world'),
]
 

upload_file.py:

 from django.views.generic.edit import FormView
from ..forms import FileFieldForm
import ipdb

def handle_uploaded_file(f):
    ipdb.set_trace()
    with open(f.name, 'wb ') as destination:
        for chunk in f.chunks():
            destination.write(chunk)

class FileFieldFormView(FormView):
    form_class = FileFieldForm
    template_name = 'reports/upload_file.html'  # Replace with your template.
    success_url = '/reports/success'  # Replace with your URL or reverse().

    def post(self, request, *args, **kwargs):
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        files = request.FILES.getlist('file_field')
        if form.is_valid():
            for f in files:
                print("hello")
                handle_uploaded_file(f)
            return self.form_valid(form)
        else:
            print("invalidated")
            return self.form_invalid(form)
 

forms.py:

 from django import forms

class FileFieldForm(forms.Form):
    title = forms.CharField(max_length=50)
    file = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True}))
 

и upload_file.html шаблон:

 {% extends "core/layout.html" %}

{% block content %}
    <br/>
    <h3>{{ title }}</h3>
    <br/>
    {% block controls %}{% endblock %}
    
    <form enctype="multipart/form-data" method="post">
        {% csrf_token %}
        {{ form.as_table }}
        <button type="submit">Upload</button>
    </form>

{% endblock %}
 

В файлах переменная в upload_file.py Я получаю список временных загруженных файлов и просто хочу сохранить их все в определенную папку, предварительно проверив их тип. Как я могу это сделать в функции handle_uploaded_file?
