Export table created in Views to a CSV with a button
Hello, I have built a view that takes in dataframes, runs them through a function and then ultimately pumps out a results dataframe that is transformed into a HTML object and displayed on the webapp homepage. Now, I am trying to add in an "Export as CSV" button that upon being clicked will download that table/dataframe to a .csv file to the user's downloads folder. Any help on how to do this? I am struggling to find anything on how specifically to do this. I was thinking maybe create a new view or function within HTML code that uses some sort of write csv function but not sure.

First View
Hello,
I use tutorial 1.11
beaumarche (startproject)
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^boutique/', include('boutique.urls')) ,
url(r'^admin/', admin.site.urls),
]
boutique (app)
urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.index, name='index'),
]
views.py
from django.http import HttpResponse
def index(request):
return HttpResponse ("Hello, world...")
127.0.0.1:8000
Using the URLconf defined in beaumarche.urls, Django tried these URL
patterns, in this order:
1.^boutique/
2^admin/
The empty path didn't match any of these
An idea maybe
Thanks

Re: Django Channels: Multiple 'send' calls in the same consumer
Thank you very much for clarifying - I wasn't exactly sure how to approach
this, but your response makes sense.
Cheers!

Django Channels: Multiple 'send' calls in the same consumer
Hi - I'm working with Django Channels (1.1.3) on a Django project and I
have some questions about how to send multiple messages from the same
consumer.
The idea is the consumer will receive a request to do some work, and will
send incremental results back to user. I've attached a simplified example
below with some questions. I'm hoping someone can steer me in the right
direction.
Django Channels:
>
> def do_some_work(message):
> for i in range(3):
> time.sleep(2)
> message.reply_channel.send({"text": 'Finished work ' + str(i)})
>
> def ws_connect(message):
> message.reply_channel.send({"accept": True})
>
> channel_routing = [
> route('websocket.connect', ws_connect),
> route('websocket.receive', do_some_work, path=r'/todo')
> ]
Javascript (borrowed mostly from the docs):
socket = new WebSocket("ws://" + window.location.host + "/todo/");
> socket.onmessage = function(e) {
> console.log(e.data);
> }
> socket.onopen = function() {
> socket.send("hello world");
> }
> // Call onopen directly if socket is already open
> if (socket.readyState == WebSocket.OPEN) socket.onopen();
Expected results: Every two seconds the browser would receive a reply from
the consumer saying 'Finished work x'.
What I observe is a delay for ~6 seconds and then all results returned at
the same time. Are the response on the reply channel blocked somehow? Is
there I way I can yield, or release the message before doing the next
increment of work?
I've also tried setting up a new consumer that *only* replies via a Group.
So instead of *message.reply_channel.send, *I would
*Channel('reply-channel').send({results:
...})* and have a new consumer defined on channel_routing for the
*'reply-channel'*. But the results are the same - all the 'work' is
completed before the browser receives a response.
Any hints on how to send multiple message in the same consumer?
Thanks in advance.

How to Allow "-" character in usernames in the admin application

Re: allowing a user to delete their own account and associated data.
Guys,
thank you, both of you, I have searched hi and low for examples of
this and found none.
A question, would the example code you have posted behave in the same
way as the delete function does in the Auth admin application, in that
it would not just delete the user, but also all the profile objects
and things like that that are associated with that username?
I got a response in a post here:
http://groups.google.com/group/pinax-users/browse_thread/thread/deda8f90e2581bc7/678332bf89130740?lnk=gst&q=delete+usres#678332bf89130740
That mentioned use of a Forien Key to get this data?

Re: allowing a user to delete their own account and associated data.
I don't suppose anyone has any insight into this do they? A pointer to where I might find the python that deletes an account in the "Auth" admin app would be great, because then I could just copy that... I've found that does everything I need, but I need to expose it to my users so they can do it themselves...

allowing a user to delete their own account and associated data.
Hello there, I'm currently learning Django by re-implementing a site based on Pinax. In the Django admin site, I can delete an account and all its associated data by going into auth > account name and deleting it. This works just dandy. What I would like to do is to expose this same functionality to the user on the main site. Can anyone point me to what views I might copy, and where from in order to achieve this, or give me any other tips? Thank you in advance.

An easy way to work with webservices and create template tags.
I'm a designer learning python and Django by example, and its a brilliant system. On my project I have a set of our own XML webservices to call using a variety of methods. The aim is to then get access to the data returned and expose the individual elements in the XML as Django template tags that I can then manipulate in my web application. I have looked at the amazon web service example, but its a little over my head. I wondered if anyone had any libraries that I might be able to adapt to do this without having to write too much python? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

FileField upload directory
Hi, Is there a way to point the FileField upload directory to somewhere that isn't under the MEDIA_ROOT ? I want this because i want to be able to upload files, but not have them accessible via the web. I've worked around this by making a new url to the upload directory and making a view which raises a Http404, which works fine, but I don't think is an ideal solution. I think having the upload_to directory point to a absolute file path rather than one relative the the media_root dir would make more sense, since users can specify the media_root if they wish, but it's not enforced. Any thoughts? Thanks, -Tristan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
