In a URL such as this one, the section after? For the sake of reducing the number of dependencies for these tutorials, we will go for the sqlite database which is directly supported by Python. If you have constructive feedback, I’d love to hear what you think!

Please see the updated post. This tutorial will walk you through basic but complete CherryPy applications that will show you common concepts as well as slightly more adavanced ones. Much like CherryPy maps URL path segments to exposed functions, query-string keys are mapped to those exposed function parameters. For the sake of our demo, this should do.

This is the reason why we open and close a connection to the database on each call. Notice how we have to convert the given length value to and integer.

In the CherryPy world, this translates into having functions that run outside xherrypy any request life-cycle. Note Unfortunately, sqlite in Python forbids us to share a connection between threads. Though, you can persist sessions on disk or in a distributed memory store, this is not the right way of keeping your data on the long run. Read the Docs v: Usually a tool is a simple Python function that is executed at a given point during the process of the request by CherryPy.

This is what goes on line 27 where we create a MethodDispatcher instance. In this example, we generate the string as in the previous tutorial but also store it in the current session. The Application mounted at ” has an empty config. Thanks for the feedback! Aug 6,
