Re: Link to download a file

[Andréas Kühne]

Hi,

I would recommend that you checkout how django uses storage backends. The
reason for that is that if you would like to use your application with a
cloud provider that has a storage solution - for example S3, your code
won't work the way it is written now.

However if you just make some minor changes - it will work directly without
any major problems.

Just do this:

view.py

from django.core.files.storage import default_storage

def download(request):
data = default_storage.open('static/tmp/dati.csv').read()
resp = HttpResponse(data, mimetype='application/x-download')
resp['Content-Disposition'] = 'attachment; filename=dati.csv'
return resp

Like I said, the reason for this is that you in the case don't have to
handle the MEDIA_ROOT settings yourself and it all works the same anyway.
Should you decide to move to a cloud provider that has some sort of storage
- you can then use the django-storages package and easily connect it,
without changing your code.

Regards,

Andréas

Thanks.
My solution:

url(r'^download/$', 'views.download', name='download'),

template.html
Download dei datiIndietro 

views.py
def download(request):
data = open(os.path.join(settings.MEDIA_ROOT, 'static/tmp/dati.csv'),

Your view should look similar to what the Django docs show here:

https://docs.djangoproject.com/en/1.11/howto/outputting-csv/

Is this a file that is publicly available? If so, it may be more efficient
to have the web server process handle the download directly rather than
Django. That would require a working setup for your STATIC_DIR and
MEDIA_DIR.

If that's the case, simply add a link to the file URL directly, something
like this in your template:

Download

Where {{ file_path }} is a path to the file in your media or static files
(if the file changes, use the media directory, if it stays the same, use
the static directory). Your web server should be configured to serve your
MEDIA_URL and STATIC_URL already.

This site appears to have several approaches detailed:

Re: Link to download a file

[giuseppe ricci]

Thank you James for your reply..
So in my urls.py I insert a new entry:

url(r'^download/$', 'views.download')

and my view to download a file is:

def download(request):
file_path = 'static/tmp/' #settings.MEDIA_ROOT
return render_to_response('download.html', file_path+'dati.csv')

and the download.html is a simple page with a write Download file ok..
But in this manner I receive the error 

TemplateDoesNotExist at /download/

static/tmp/dati.csv


Can you help me?

Thanks.

There's a few ways to handle this.

1. Your 'download' button could simply be a link back to the same page with
an additional GET argument (ie ?download= ). In your view, you would
generate the data dict normally. Before you start returning responses
though, you would check for the presence of the 'download' GET argument via
request.GET.get('download', False). If you get anything but False (meaning
they clicked the link), you can tweak the response headers and send back
only the data you've gathered:

https://docs.djangoproject.com/en/dev/ref/request-response/#telling-the-browser-to-treat-the-response-as-a-file-attachment

Depending on what kind of file you are returning, you may need to create an
in memory file using StringIO or BytesIO and return that.

If you want to have a separate view handle the file download, simply add
something like '/download/' to the end of the URL as another urls.py entry,
and assume that the user wants to download the file within the view you
specify for your URL. If you do that, I suggest you break out the CSV
reading/writing logic (along with and file creation work) in to separate
functions from the view so that both views access the data in the same way,
they simply render and return it differently.

Another way would be to accept a POST submission through a form and then
return the file as I explained above.

That's an interesting project!

If I use WhiteNoise as part of a production deploy somewhere, can I skip 
(or ignore) running 'manage.py collectstatic' ?

Beware that, if your content can get huge (some of our reports can
run to hundreds of megabytes), you might want to investigate
something like the "sendfile" alternatives or spew it out as generator
instead of doing .read() to suck the whole thing into memory.

You /can/ get a file outside your project. Whether this is a bad thing or not
depends on why and how. I also don't think this file should be placed in the
static directory. The static directory is for files that don't change after the
program is installed. The media directory might be more appropriate.

If what you are doing is to dynamically create a csv file for your user to
download immediately, one possible way of doing that is (untested):

from tempfile import TemporaryFile

csvfile = TemporaryFile()
export_your_data_to_the_file(csvfile)
file_size = csvfile.tell()
csvfile.seek(0)
response = HttpResponse(csvfile.read(), content_type='text/csv')
response['Content-Disposition'] = 'attachment; filename=whateveryoulike.csv'
response['Content-Length'] = str(size)
return response

Re: Link to download

[m712 - Developer]

You cannot get a file outside of your project unless you symlink it inside the 
project. This is also a Very Bad Thing(TM) as it may allow attackers to request 
arbitrary files.
What you should do instead is this:
1) Put Data/01/export.txt to the static/ folder inside your app (with the same 
folder structure if you need it that way)
2) Build the path to your file with /static/ as prefix, i.e. 
http://127.0.0.1/static/Data/01/export.txt

Re: Link to download

[Sixtine Vernhes]

This is in development. I try to send url of my file in views.py : 
   
 return render(request, "export.html", {'out': urlOut})

and in my template I have the link : 

Lien du  fichier 

but when I open it I have this link : 

http://127.0.0.1:8000/home/myuser/Data/01/export.txt 

and I want to have this to download the file : 
/home/myuser/Data/01/export.txt 

Have you any ideas? 

(sorry i'm newbie in django ^^)

Link to download

[Sixtine Vernhes]

Hi ! 

I try to create a link on Django who download a static csv file, but I have 
no idea how to do. 
In my settings.py :

STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "static/"),
)

and my file is in this directory 

Would anyone have an idea ?
