django_client_data 0.1.7

This allows Django to export JSON-compatible data to the browser.

Latest Version: 0.1.9

This allows Django to export JSON-compatible data to the browser. The client-side code accesses the data as a JavaScript object.

Installation

To get the latest stable release from PyPi

pip install django_client_data

Install the app, middleware, and context processor

INSTALLED_APPS = (
    ...,
    'django_client_data',
)

MIDDLEWARE_CLASSES = (
    ...
    'django_client_data.middleware.ClientDataMiddleware',
)

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'django_client_data.context_processors.client_data',
)

Usage

Call set_client_data() in your view to export values

from django.views.generic import TemplateView
from django_client_data import set_client_data


class IndexView(TemplateView):
    template_name = 'index.html'

    def get(self, request, *args, **kwargs):
        set_client_data(request, **{'foo': 'bar'})
        return super(IndexView, self).get(request, *args, **kwargs)

Include client_data.html in your page

{% include 'django_client_data/client_data.html' %}

The JavaScript object DJANGO.client_data will look like

{
    "DEBUG": false,
    "STATIC_URL": "/static/",
    "csrftoken": "gSlpOPyxHrdQH3KWUEkXx1wfyqGE7MDo",
    "foo": "bar",
    "url_args": [],
    "url_kwargs": {},
    "url_name": "index",
    "user_full_name": null,
    "user_pk": null,
    "username": null
}

Settings

CLIENT_DATA_NAMESPACE (defaults to ‘DJANGO’) is the JavaScript global that will be created as the namespace to contain the client data. The data is a property of this global and is named ‘client_data’.

Mechanism

Django Client Data works by attaching a client_data attribute on the request object. The client_data.html template attaches a client_data property to the JavaScript global indicated by CLIENT_DATA_NAMESPACE.

Todo

  • Add a “context processors” feature to client data so custom values can be injected
