Disclaimer

==========



Telegraphy (master) is based on WAMP_ 1.0. We're rewritting it to use a more advanced broker called `crossbar.io`_ for asynchronous operations.



Currentrly development is being made in crossbario_ branch.

Telegraphy

==========



Telegraphy provides real time events for WSGI Python applications with additional

features such as event filtering, subscription persistence and authorization/authentication.



It's initially intended for Django but you can extend it to any WSGI framework.



WebSocket pub/sub and RPC is based on AutobahnPython_ implementation of `WAMP protocol`_

Getting It

==========



You can get *Telegraphy* by using pip::



 $ pip install telegraphy



You will need to have pip installed on your system. On linux install the python-pip package,

on windows follow `this `_.

Also, if you are on linux and not working with a virtualenv, remember to use ``sudo``

for both commands (``sudo pip install telegraphy``).



If you want to install it from source, grab the git repository from GitHub and run setup.py::



 $ git clone git://github.com/machinalis/telegraphy.git

 $ cd telegraphy

 $ python setup.py install



Installing the Django app

=========================



Telegraphy's Django app is installed with the standard procedure:  in your projects `settings.py` file

add `telegraphy.contrib.django_telegraphy` to the `INSTALLED_APPS`::



 INSTALLED_APPS = (

     ...

     'telegraphy.contrib.django_telegraphy',

     ...

 )



Using It

========



The django_telegraphy app allows you to easily extend your models so that they generate events

on creation, update or delete. Those events will reach your front end in real time.



Simply install the django_telegraphy app in your Django project. Then run the following command

in parallel to your web-server::



 $ python manage.py run_telegraph



Extend your models so that they automatically generate events: create an ``events.py`` file next to your ``models.py``



.. code-block:: python



    from models import MyModel

    from telegraphy.contrib.django_telegraphy.events import BaseEventModel



    class MyEventsModel(BaseEventModel):

        model = MyModel



Finally, prepare some template to receive and show the events:



.. code-block:: html+django



    {% load telegraphy_tags %}

    {% load static %}

    

        

            Simple Telegraphy API Example

            

            {% telegraphy_scripts %}

        

        

            
Catching model events!


            
     


            

                (function (){

                    var $event_catcher = $('#event_catcher');

                    Telegraphy.register('your_app.MyModel',

                        function (tEvent){

                            console.log("Event", tEvent);

                            var new_line = $('<li/>').text("New instance");

                            $event_catcher.append(new_line);

                        });

                })();

            

        

    



And that's it! Every time you create, update or delete an instance of your model, an event will reach your template.



You can find more `examples in the documentation `__.
