I'm trying to get Django to upload a file (keeping it simple, for now), but am having difficulties. Here's all of the relevant code (that I know of). Perhaps something is wrong with my settings.py? My code is pieces of various answers on Stack Overflow. I've checked here already.
When I select a file (~8.5mb file because I saw Django does something funny if it is under 2.5mb) and press Submit, I am brought to the Upload Success page, but can't seem to find my file anywhere in my project directory.
I am using the development runserver with apache running just for serving images.
settings.py
MEDIA_ROOT = '/Users/adam/Documents/workspace/sitename/media'
MEDIA_URL = 'http://127.0.0.1:8000/media/'
STATIC_ROOT = '/Library/WebServer/Documents/static/'
STATIC_URL = 'http://10.0.1.15/static/'
ADMIN_MEDIA_PREFIX = '/media/admin/'
STATICFILES_DIRS = (
)
*the static URL is the address of my local apache webserver.
urls.py
urlpatterns = patterns('',
('^$', index),
('^uploadfile/$', uploadfile),
('^uploadsuccess/$', uploadsuccess),
)
if settings.DEBUG:
from django.views.static import serve
_media_url = settings.MEDIA_URL
if _media_url.startswith('/'):
_media_url = _media_url[1:]
urlpatterns += patterns('',
(r'^%s(?P<path>.*)$' % _media_url,
serve,
{'document_root': settings.MEDIA_ROOT}))
del(_media_url, serve)
views.py
def uploadsuccess(request):
return render_to_response('uploadsuccess.html', {})
class UploadFileForm(forms.Form):
file = forms.FileField()
def uploadfile(request):
if request.method == 'POST':
form = UploadFileForm(request.POST, request.FILES)
if form.is_valid():
handle_uploads(request.FILES['file'])
form.save()
return HttpResponseRedirect('/')
else:
form = UploadFileForm()
return render_to_response('fileupload.html', {'form': form}, context_instance=RequestContext(request))
def handle_uploads(file):
logging.debug("upload_here")
if file:
destination = open('/tmp/'+file.name, 'wb+')
for chunk in file.chunks():
destination.write(chunk)
destination.close()
fileupload.html
<html>
<body>
<h1>Upload a file</h1>
<form enctype="multipart/form-data" method="post" action="/uploadsuccess/">
{% csrf_token %}
<table>
{% for field in form %}

You are posting data to the wrong URL, change action="/uploadsuccess/" to /uploadfile/.

Many Thanks,
I have resolved this issue by adding static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) to the main urls.py file. I hope this help.
When I use the form provided by django admin everything works fine. But after creating my own form, django does not write data to my model. Is something missing in my code?
Models.py
class Offert(models.Model):
name = models.CharField(max_length=50)
file = models.FileField(upload_to='app/documents/')
forms.py
class OffertFormCV(forms.ModelForm):
class Meta:
model = Offert
fields = ( 'name',
'file')
views.py
def my_views(request):
if request.method == 'POST':
form = OffertFormCV(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect(reverse('app:thank_you_page'))
else:
form = OffertFormCV()
context = {'form': form}
return render(request, 'form_application.html', context)
urls.py
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('app.urls', namespace='app'))
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
settings.py
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'app/media')
form_application.html
<form method="post">
{% csrf_token %}
{{ form|crispy }}
<button type="submit" class="btn btn-primary">Send</button>
</form>
After sending the form, nothing happens. Any help will be appreciated.
You need to add enctype="multipart/form-data" to your form to be able to upload files:
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form|crispy }}
<button type="submit" class="btn btn-primary">Send</button>
</form>
I've been struggling with this for so long that I'm bordering depression.
I have a model called "Song" that looks like this.
from django.db import models
class Song(models.Model):
title = models.CharField(max_length=100)
songfile = models.FileField()
duration = models.FloatField()
isPlaying = False
def __str__(self):
return self.title
When you upload an mp3 file from the index page, it creates an instance of this model and stores the file in myapp/songdir/ using this view:
def home(request):
if request.method == 'POST':
form = UploadForm(request.POST, request.FILES)
if form.is_valid():
song_title = request.POST.items()[1][1]
song_address = 'upnplay/songdir/' + song_title + '.mp3'
with open(song_address, 'wb+' ) as destination:
for chunk in request.FILES['file'].chunks():
destination.write(chunk)
audio = MP3(song_address)
c = Song(title = song_title, songfile = song_address, duration = audio.info.length)
c.save()
return HttpResponseRedirect('')
else:
form = UploadForm()
c = {'form': form}
c.update(csrf(request))
return render(request, 'index.html', {'form': form})
Then I have a template called "choosesong" that displays a list of songs that I get from the model instances saved:
{% extends 'index.html' %}
{% block content %}
<div class="row">
{% for song in playlist %}
<h3>{{song.title}} -- {{song.duration}}</h3>
{% endfor %}
</div>
{% endblock %}
{% block form %}{% endblock %}
When I click on one of this links, I want a new template to be rendered, with a element that plays the song whose name I clicked. The template that I render is this one:
{% extends 'index.html' %}
{% block content %}
<div class='row'>
{{link}}
<audio controls>
<source src="../../{{ link }}" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
</div>
{% endblock %}
And the view I use to deliver it is the following:
def playAudioFile(request, songtitle):
name = urllib.unquote(songtitle)
song = get_object_or_404(Song, title=name )
return render(request, 'playlist.html', {'link': song.songfile })
For some reason I can't get it to play the song inside the audio element and I don't know what else to try.
Thank you beforehand.
You should add MEDIA_ROOT and MEDIA_URL configuration. It will be easy to handle things. Here is the solution to your problem.
In settings.py:
MEDIA_ROOT=os.path.join(BASE_DIR,"songdir")
MEDIA_URL='/media/'
Also in settings.py add
'django.template.context_processors.media',
in the TEMPLATES option's context_processors.
In project/urls.py:
from django.conf import settings
from django.conf.urls.static import static
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
Then you can simply use:
{{link.url}}
instead of hardcoding it in your template file.
I have overridden my admin change_list.html
{% extends "admin/change_list.html" %}
{% block object-tools-items %}
<li>
Import CSV
</li>
{{ block.super }}

When I click this Import CSV link, I would like to import CSV and save to my model.
App's name Auction. Objects of Auction:
forms.py
from django import forms
import csv
from auction.models import AuctionGroup, AuctionHouse, AuctionList
class DataInput(forms.Form):
file = forms.FileField()
def save(self):
records = csv.reader(self.cleaned_data["file"])
for line in records:
house = AuctionHouse()
house.house_name = line[0]
house.auction_type = line[1]
house.auction_day = line[2]
house.volume = line[3]
house.aleado_id = line[4]
house.aleado_photo_number = line[5]
house.house_region = line[6]
house.save()
views.py
def csv_import(request):
if request.method == "POST":
form = DataInput(request.POST, request.FILES)
if form.is_valid():
form.save()
success = True
context = {"form": form, "success": success}
return render_to_response("auction/importcsv.html", context,
context_instance=RequestContext(request))
else:
form = DataInput()
context = {"form": form}
return render_to_response("auction/importcsv.html", context,
context_instance=RequestContext(request))
urls.py
urlpatterns = patterns('',
url(r'/importcsv/$', views.csv_import, name='importcsv'),
)
project/urls.py
urlpatterns = patterns('',
url(r'^auction/', include('auction.urls')),
url(r'^admin/', include(admin.site.urls)),
)
importcsv.html
<!DOCTYPE html>
<html>
<form enctype="multipart/form-data" method="post" action=".">
{{ form }}
</form>
</html>
But it does not work. Please, help. Regards
Use the {% url %} tag in the link code:
Import CSV
If you want to use single template for multiple models then change_list.html has the cl.opts context variable which is a Model._meta of the current model.
So you can pass the app_label and model_name to your importcsv() view:
<a href="{% url 'importcsv' cl.opts.app_label cl.opts.model_name %}"
class="grp-state-focus addlink">Import CSV</a>
Change your urls.py:
urlpatterns = patterns('',
url(r'/importcsv/(\w+)/(\w+)/$', views.csv_import, name='importcsv'),
)
And the signature of the view function:
def csv_import(request, app_label, model_name):
...
