Re-usable bussiness components, modular units on a page

Project description


The goal of `django-webnodes` is to create a new way of writing django templates which is fully compatible with the current django templating infrastructure.

It's born to make it easy to support standard, reusable `bussiness components` across your application.

`django-webnodes` are like special functional calls to render components of your page.

## Usage:

This use as django templatetags

{% webnode node_name [value1 value2 ... key1=value1 key2=value2 ...] %}

- ``value1``: position value passed as ``value1`` in ``get_context()`` and ``render()`` methods
- ``key1=value1``: dictionary key-value pairs passed as ``key1`` in ``get_context()`` and ``render()`` methods

## Demo

For example, if you are implementing a app statistics website, and you want to have app ratings appear on both list page and detail page, you can make an `RatingsNode` to render them on both pages.

First, create a Python module for your webnodes, e.g., it in ``yourapp`` module)

from webnodes import WebNode

class RatingsNode(WebNode):

template = 'webnodes/ratings.html'

def get_context(self, app_id):
ratings = ...
return {'ratings': ratings}

Calling from template:

{% load webnode %}

<p>{% webnode RatingsNode %}</p>

## Extension

If you want see this webnode independently, you can add this in your urls' urlpatterns

url(r'^webnodes/', include('webnodes.ext.urls'))

Then open `` in your browser, you will see it.

## Why use this?

1. Decoupling the logic of front-end and back-end separately;
2. Make each component as a webnode will improve cohesion(because each component's template and data(include the logic of fetch data) are always strongly correlated);
3. We can test each component independently;
4. easy to realize partial renewal.

## Todos

support css and javascript
