Recently I was working on a project that accesses a third-party webservice. The service does not handle concurrency well, and crashes if you send more than a few requests at the same time. To prevent it from getting overloaded, I implemented a semaphore with Postgres and Django.

Partial Word Search With Postgres Full Text Search in Django

Posted by brad on Sept. 6, 2017, 10:19 a.m.

Django provides support for using Postgres's full text search feature, but there is no way to use this Django support to achieve the partial word search functionality one might find easy to implement with Django Haystack and Solr. This post describes a simple way to enable partial word search in Django without having to rely on solr and Haystack by writing a small amount of raw SQL.

Posted by nolan on June 23, 2017, 3:48 p.m.

Django offers developers the ability to create custom fields that use custom html widgets, but is it possible to build a field that asks a user to provide a number of inputs undetermined before runtime? I'll take a project—the development of a field that allows a user to resolve any URL on the site—and try to answer that question, digging deep into the internals of Django's fields and widgets along the way.
