Usage
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 jinja2After 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_quickstart.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 responseOr, 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 responseLicense
