Create a file uploader with Django
I updated it because it has old information and ugly code. (2017/03/16)
environment
- Python 3.5.1
- Django 1.9.1
- Virtualenv 15.0.1
- OS X El Capitan 10.11.6
Final configuration

I think it would be nice if it had a structure like this.
__pycache__ is omitted
setup
Project creation
$ pip install Django==1.9.1
$ django-admin.py startproject file_uploader
$ cd file_uploader
$ django-admin.py startapp upload_form
#I want to check which file was uploaded when
$ python manage.py createsuperuser

I wonder if it should be
Confirm for the time being
$ python manage.py migrate
$ python manage.py runserver
http://127.0.0.1:8000
If you access and the example is out, it's OK
ʻUpload_form` Build App
models.py
upload_form/models.py
from django.db import models
from datetime import datetime
class FileNameModel(models.Model):
file_name = models.CharField(max_length = 50)
upload_time = models.DateTimeField(default = datetime.now)
file_name: File name
ʻUpload_time`: Upload date and time (default is the current date and time)
views.py
upload_form/views.py
from django.shortcuts import render, redirect
from django.template.context_processors import csrf
from django.conf import settings
from upload_form.models import FileNameModel
import sys, os
UPLOADE_DIR = os.path.dirname(os.path.abspath(__file__)) + '/static/files/'
def form(request):
if request.method != 'POST':
return render(request, 'upload_form/form.html')
file = request.FILES['file']
path = os.path.join(UPLOADE_DIR, file.name)
destination = open(path, 'wb')
for chunk in file.chunks():
destination.write(chunk)
insert_data = FileNameModel(file_name = file.name)
insert_data.save()
return redirect('upload_form:complete')
def complete(request):
return render(request, 'upload_form/complete.html')

Uploading Maybe there is no upload destination directory! Because you may get angry Create a directory with a structure like ʻupload_form / static / files /`.
URL setting
urls.py
ʻUpload_form / urls.py` is newly created and the following
upload_form/urls.py
from django.conf.urls import url
from upload_form import views
urlpatterns = [
url(r'^$', views.form, name = 'form'),
url(r'^complete/', views.complete, name = 'complete'),
]
file_uploader/urls.py
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('upload_form.urls', namespace = 'upload_form')),
]
Django admin site settings
admin.py
upload_form/admin.py
from django.contrib import admin
from upload_form.models import FileNameModel
class FileNameAdmin(admin.ModelAdmin):
list_display = ('id', 'file_name', 'upload_time')
list_display_links = ('id', 'file_name')
admin.site.register(FileNameModel, FileNameAdmin)
Allow data to be viewed and edited from the Django admin site
Migration & launch
$ python manage.py makemigrations
$ python manage.py migrate
$ python manage.py runserver
http://127.0.0.1:8000 When you visit, you'll see a crappy web page. If you upload it properly from there, it will work.
http://127.0.0.1:8000/admin/ Go to and log in http://127.0.0.1:8000/admin/upload_form/filenamemodel/ Make sure you have the data when you enter! !!
For some reason, the uploaded files are only iOS Certificate and p12 files, so I'm sorry but I was able to confirm!
The rest is baking or simmering.
When I uploaded a CSV file at my graduate school last year, I read the contents and inserted it into the DB table.
