Question

I am new to django, I am trying to upload more than one file from the browser and store them somewhere in computer storage but I am not storing them successfully with this code please help me out to find my mistake or improvements that I can do. Thanks in advance to help.
views.py
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def Form(request):
return render(request, "index/form.html", {})
def Upload(request):
for count, x in enumerate(request.FILES.getlist("files")):
def process(f):
with open('/Users/benq/djangogirls/upload/media/file_' + str(count), 'wb+') as destination:
for chunk in f.chunks():
destination.write(chunk)
process(x)
return HttpResponse("File(s) uploaded!")
app/urls.py
from django.conf.urls import url
from index import views
urlpatterns = [
url(r'^form/$', views.Form),
url(r'^upload/$', views.Upload)

form.html
<form method="post" action="../upload/" entype="multipart/form-data"> {% csrf_token %}

Answer 1

my model to save Document
class Document(models.Model):
file = models.FileField('Document', upload_to='mydocs/')
#property
def filename(self):
name = self.file.name.split("/")[1].replace('_',' ').replace('-',' ')
return name
def get_absolute_url(self):
return reverse('myapp:document-detail', kwargs={'pk': self.pk})
you can try a django create view in my code i use this DocumentCreateView
class DocumentCreate(CreateView):
model = Document
fields = ['file']
def form_valid(self, form):
obj = form.save(commit=False)
if self.request.FILES:
for f in self.request.FILES.getlist('file'):
obj = self.model.objects.create(file=f)
return super(DocumentCreate, self).form_valid(form)
my form html file
<script>
$(document).ready(function(){
$('#id_file').attr("multiple","true");
})
</script>
<form method="post" enctype="multipart/form-data" action="">{% csrf_token %}
{{ form.file }}
<input type="submit" value="upload" />
</form>

Answer from official django documentation
file_field = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True}))
https://docs.djangoproject.com/en/3.0/topics/http/file-uploads/#uploading-multiple-files

views.py
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def Form(request):
for x in request.FILES.getlist("files"):
def process(f):
with open('/Users/benq/djangogirls/upload/media/file_' + str(x), 'wb+') as destination:
for chunk in f.chunks():
destination.write(chunk)
process(x)
return render(request, "index/form.html", {})
urls.py
from django.conf.urls import url
from index import views
urlpatterns = [
url('form', views.Form),
]
worked for me.

Just an update from Django 3.2 and above. According to docs you have to:
If you want to upload multiple files using one form field, set the multiple HTML attribute of field’s widget:
from django import forms
class FileFieldForm(forms.Form):
file_field = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True}))
Then override the post method of your FormView subclass to handle multiple file uploads:
from django.views.generic.edit import FormView
from .forms import FileFieldForm
class FileFieldView(FormView):
form_class = FileFieldForm
template_name = 'upload.html' # Replace with your template.
success_url = '...' # 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:
... # Do something with each file.
return self.form_valid(form)
else:
return self.form_invalid(form)

I was able to solve the multi uploads portion in the create view here: Django Class based UpdateView with Form for Multiple Uploaded Files , however, now the update get function is what I am currently stuck on.
