jinja2 template renderer for aiohttp.web (http server for asyncio)

Project description


jinja2 template renderer for aiohttp.web.


Install from PyPI:

pip install aiohttp-jinja2


Install requirement and launch tests:

pip install -r requirements-dev.txt
py.test tests


Before template rendering you have to setup jinja2 environment first:

app = web.Application()


import aiohttp_jinja2
import jinja2

After that you may to use template engine in your web-handlers. The most convenient way is to decorate a web-handler.

Using the function based web handlers:

def handler(request):
    return {'name': 'Andrew', 'surname': 'Svetlov'}

Or for Class Based Views <>:

class Handler(web.View):
    async def get(self):
        return {'name': 'Andrew', 'surname': 'Svetlov'}

On handler call the aiohttp_jinja2.template decorator will pass returned dictionary {'name': 'Andrew', 'surname': 'Svetlov'} into template named tmpl.jinja2 for getting resulting HTML text.

If you need more complex processing (set response headers for example) you may call render_template function.

Using a function based web handler:

async def handler(request):
    context = {'name': 'Andrew', 'surname': 'Svetlov'}
    response = aiohttp_jinja2.render_template('tmpl.jinja2',
    response.headers['Content-Language'] = 'ru'
    return response

Or, again, a class based view:

class Handler(web.View):
    async def get(self):
        context = {'name': 'Andrew', 'surname': 'Svetlov'}
        response = aiohttp_jinja2.render_template('tmpl.jinja2',
        response.headers['Content-Language'] = 'ru'
        return response
