This is a simple-to-use connector to implement Tryton-based models in the Tornado web app. The realization is based on the flask-tryton module. Tornado — is a non-blocking I/O framework that is the most suitable for high-performance back-end applications.
Some discussion on Hackernoon about it.
Tornado is a well-suited powerful framework to build a lightweight Tryton-based backend. It is easy to deploy and debug.
Here you may find the module:
Currently, it is under active development.
Install:
pip install tornado-tryton
Use:
It is not recommended to use URL variables for password transmission as it may be recorded in server log files, and it is advised to move auth data into a request headers section. In the example, a simpler approach was used for simplicity, though.
