__ aiohttp_web_
Install from PyPI::
pip install aiohttp-jinja2
Install requirement and launch tests::
pip install -r requirements-dev.txt
pytest tests
Before template rendering you have to setup jinja2 environment first:
.. code-block:: python
app = web.Application()
aiohttp_jinja2.setup(app,
loader=jinja2.FileSystemLoader('/path/to/templates/folder'))
Import:
.. code-block:: python
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:
.. code-block:: python
@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>:
.. code-block:: python
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:
.. code-block:: python
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:
.. code-block:: python
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

No elaborate configuration is needed. * Simple Things Remain Simple: Writing HTTP controllers is similar to how it's done in the synchronous code. Controllers have new exciting features that take advantage of the asynchronous environment. * Consistency is Key: You can keep the same approach to writing software no matter the size of your project. There are no growing central configuration files or service dependencies registries. Every relation between code modules is local to those modules. * Promises in PHP: Resonance provides a partial implementation of Promise/A+ spec to handle various asynchronous tasks. * GraphQL Out of the Box: You can build elaborate GraphQL schemas by using just the PHP attributes. Resonance takes care of reusing SQL queries and optimizing the resources' usage. All fields can be resolved asynchronously.
