Wagtail: 2 Steps for Adding Pages Outside of the CMS
My first Caktus project went live late in the summer of 2015. It's a community portal for users of an SMS-based product called RapidPro. The portal was built in the Wagtail CMS framework which has a lovely, intuitive admin interface and excellent documentation for developers and content editors.

Climbing up Branches
Today I pushed the latest Evennia development branch "wclient". This has a bunch of updates to how Evennia's webclient infrastructure works, by making all exchanged data be treated equal (instead of treating text separately from other types of client instructions).It also reworks the javascript client into a library that should be a lot easier to expand on and customize. The actual client GUI is still pretty rudimentary though, so I hope a user with more web development experience can take upon themselves to look it over for best practices. A much more detailed description of what is currently going on (including how to check out the latest for yourself) is found in this mailing list post. Enjoy! -

Just one comma
In Django, if you say managed = False in a model's Meta, you tell Django not to touch the database table. So: no automatic database migrations, for instance. Now, what is the problem if you have managed = False, and Django does do migrations? Some of you will have seen the error already. The comma after False is the problem: >>> a = False, >>> a (False,) >>> bool(a) True The comma turns it into a tuple. And a non-empty tuple evaluates to True! I found it quite funny. My colleague was torn between "extremely relieved" and "extremely annoyed" :-)
