Django-Twilio sending SMS on button click

Question

OK possible noob question here: While learning Django, I thought it might be cool to explore telephony with Twilio. My immediate goal is to create a page with a button that, when clicked, causes a "Hello World" SMS to be sent to my phone. After sorting that out I have some ideas for cooler stuff.

I've completed several Django tutorials so far, and made a few little apps with simple views. But nothing I've learned has particularly shed any light on how to do something like this. I've also investigated (and installed) the Django-Twilio app and the Twilio Python Helper Library, but the docs for neither of these show how to send "hello world" SMS's.

Can anyone point out a resource that might show how to do this? Or, if it's trivially easy, just post some example code?

Edit in response to Kevin Burke:

Thanks for getting back to me, Kevin. After modifying my urls.py to include:

urlpatterns = patterns('',
# ...
url(r'^sms/$', 'django_twilio.views.sms', {
    'message': 'Hello world',
    'to': '+12223334444',
    'sender': '+18882223333',
    'status_callback': '/sms/completed/',
    }, name = 'send_message'),
# ...
)

and pointing my browser at

http://127.0.0.1:8000/sms/

the following error arises:

Exception Type: TwimlException at /sms/
Exception Value: Invalid method parameter, must be 'GET' or 'POST'

Perhaps this is because I have failed to make appropriate modifications to the view. But I don't have a good way of figuring out what I'm doing wrong from the minimal examples in the tutorial. /Edit

It's a little tricky to help out without knowing more about your situation. It's definitely possible to send "Hello World" using the twilio-python helper library, see for example twilio.com/docs/python/install, but without knowing where you are getting stuck it's tricky to offer more feedback. — Kevin Burke

twilio employee here. The problem here is that the built in views for django_twilio run through a series of validation checks to make sure they're receiving content from twilio.com and only twilio.com. This is a security measure built into django-twilio.

There are two things you can do:

Make sure your settings.DEBUG = True in your Django settings, this will turn off the validation. You can then send a cURL request on your local machine whilst it is running like this in your terminal:
```
$ curl http://localhost:8000/sms/
```
This should return some TWiML like so:
```
<Response><Sms>Hello world</Sms></Response>
```
When you're running this online and you want to do to test this, set up your twilio number to point to http://mywebsite.com/sms/ and text the number. Ensure that settings.DEBUG = False and you should get back a message.

If you have anymore problems, let me know.

Here's the official docs: django-twilio official docs. More specifically, read this part about sending SMS: Sending sms messages

Here is a simple solution :

django startproject projectname

urls.py

from django.conf.urls import url, include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include('message_api.urls')),
]

settings.py

TWILIO_ACCOUNT_SID = TWILIO_ACCOUNT_SID
TWILIO_AUTH_TOKEN = TWILIO_AUTH_TOKEN
DJANGO_TWILIO_FORGERY_PROTECTION = False
DJANGO_TWILIO_BLACKLIST_CHECK = True

Start new application

python manage.py startapp appname

Inside the app folder:`

urls.py

from django.conf.urls import url
import django_twilio
from . import views

urlpatterns = [
     url(r'^api/$', views.home),
     url(r'^send/', views.sms),
]

views.py

from django.shortcuts import render
from twilio.rest import Client
from twilio_api import settings

def home(request):
    return render(request, 'index.html', {})

def sms(request):
    client = Client(settings.TWILIO_ACCOUNT_SID, settings.TWILIO_AUTH_TOKEN)

    message = client.messages.create(to='TO NUMBER', from_='YOUR TWILIO NUMBER', body='This message is sent through twilio api using django framework by akshat.')

    print(message.sid)

    return render(request, 'thankyou.html')

Make a templates directory inside your app folder

index.html

<body>
<a href="/send/"><button class="btn btn-outline-primary">Send Message</button></a>
</body>

thankyou.html

<body>
<h1>Success</h1>
</body>

`

where the message sends action done. Is it in print(message.sid) ??
