Yesterday Cerberus 0.8.1 was released with a few little fixes, one of them being more a new feature than a fix really: sub-document fields can now be set as field dependencies by using a ‘dotted’ notation. So, suppose we set the following validation schema: schema = { 'test_field': { 'dependencies': [ 'a_dict.foo', 'a_dict.bar' ] }, 'a_dict': { 'type': 'dict', 'schema': { 'foo': {'type': 'string'}, 'bar': {'type': 'string'} } } } Then, we can validate a document like this: ...

Eve 0.5.2 has just been released with a bunch of interesting fixes and documentation updates. See the changelog for details.

Tom Christie has some very good things to say on how to successfully maintain an open source project without losing sanity. Truth one: There are, and will always be, a non-finite number of possible valid issues to address. Your code can always be better polished, your APIs better defined, and your project more fully featured. Your documentation can always be better. The ecosystem within which your project lives is constantly evolving. You will never run out of things you could work on. Ever. ...

Flask-Sentinel is a OAuth2 Server implementation of the Resource Owner Password Credentials Grant pattern described in Section 1.3.3 of RFC 6749. It is powered by Flask-Oauthlib, Redis and MongoDB and is bundled as a Flask extension so it can be used to add OAuth2 capabilities to an existing application. So what is the Resource Owner Password Credentials Grant pattern? According to the official RFC: The resource owner password credentials (i.e., username and password) can be used directly as an authorization grant to obtain an access token. The credentials should only be used when there is a high degree of trust between the resource owner and the client (e.g., the client is part of the device operating system or a highly privileged application). ...

Eve 0.5.1 was just released with a couple fixes to 0.5 (which was released earlier this week.) Don’t be surprised. Going forward I’m striving for a much faster release cycle, especially so when it comes to fixes.

Powered by SQLAlchemy and good intentions, Eve-SQLAlchemy is an official Eve extension which allows to effortlessly build and deploy highly customizable, fully featured RESTful Web Services with SQL backends. As with all Eve extensions, once installed with $ pip install eve-sqlalchemy using Eve-SQLAlchemy is very simple: from eve import Eve from eve_sqlalchemy import SQL app = Eve(data=SQL) app.run() On a fresh virtualenv (of course you are using virtualenvs, right?) the install will also setup Eve and all its dependencies for you. For a complete tutorial you can visit the Eve-SQLAlchemy Support Website. ...

A lot of servers have been including a JeSuisCharlie header with their responses. If you haven’t already, try with Charlie Hebdo site itself: $ curl -I charliehebdo.fr Date: Mon, 12 Jan 2015 15:56:13 GMT Content-Type: text/html; charset=iso-8859-1 Content-Length: 221 Connection: keep-alive Location: http://www.charliehebdo.fr/index.html Vary: Accept-Encoding X-Charlie-fr: Je suis toujours Charlie. X-Charlie-en: I am still Charlie. X-Charlie-es: Todavia soy Charlie. X-Charlie-de: Ich bin immer Charlie. X-Charlie-ro: Inca sunt Charlie. X-Charlie-cz: Jsem stale Charlie. I find this to be a great way for us techies to somehow contribute and show support for the ongoing anti-terrorism campaign. So if you feel like doing it here is a quick rundown on how to serve custom headers with your Eve-powered REST API. It is actually a very easy task to accomplish. ...

People keep telling me that they want to validate class and instance attributes (object properties) with Cerberus. While it certainly wasn’t conceived with that goal in mind, it is actually very possible to leverage both the Python data model and Cerberus extensibility to achieve object validation. Nuts & Bolts Let’s say that we have a simple class: >>> class Person(object): ... pass We create a Person instance and add a few properties and values: ...
