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() aiohttp_jinja2.setup(app, loader=jinja2.FileSystemLoader('/path/to/templates/folder'))
Import:
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:
@aiohttp_jinja2.template('tmpl.jinja2') def handler(request): return {'name': 'Andrew', 'surname': 'Svetlov'}
Or for Class Based Views <https://aiohttp.readthedocs.io/en/stable/web.html#class-based-views>:
class Handler(web.View): @aiohttp_jinja2.template('tmpl.jinja2') 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', request, context) 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', self.request, context) response.headers['Content-Language'] = 'ru' return response
