## japronto_jinja2

[jinja2](http://jinja.pocoo.org) asynchronous template renderer for [japronto](https://github.com/squeaky-pl/japronto).

### Installation

Install from PyPI: ` pip install japronto-jinja2 `

### Developing

Install requirement and launch tests: ` pip install -e .[dev] pytest `

### Usage

Before template rendering you have to setup jinja2 environment first:

import jinja2
from japronto import Application

app = Application()
japronto_jinja2.setup(app, loader=jinja2.FileSystemLoader('/path/to/templates/folder'))

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:

@ajapronto_jinja2.template('tmpl.jinja2')
def handler(request):
    return {'action': 'follow', 'person': 'me'}

On handler call the japronto_jinja2.template decorator will pass returned dictionary {‘action’: ‘follow’, ‘person’: ‘me’} into template named tmpl.jinja2 for getting resulting HTML text.

If you need more complex processing (modify response on your own) you may call render_template function.

Using a function based web handler:

async def handler(request):
    context = {'action': 'unsubscribe', 'from': 'channel'}
    response = aiohttp_jinja2.render_template('tmpl.jinja2',
                                              request,
                                              context)
    # do smth with your response
    return response
