[... 629 words]Django SQL Dashboard 1.0 (via) As part of my ongoing attempt to be braver about 1.0 releases (crucial if you want to do semantic versioning properly) I’ve released version 1.0 of Django SQL Dashboard, my Datasette-inspired app for Django that adds an interface for running read-only, bookmarkable SQL queries against a PostgreSQL database. The new version adds a column cog menu providing shortcuts for changing the sort order, counting distinct values and performing a group-by/count against column values. # 1st July 2021, 5:44 pm

Appending the request URL to SQL statements in Django. A clever frame-walking monkey-patch which pulls the most recent HttpRequest object out of the Python stack and adds the current request.path to each SQL query as an SQL comment, so you can see it in debugging tools such as slow query logs and the PostgreSQL “select * from pg_stat_activity” query. # 2nd June 2010, 9:09 am
django-batch-select (via) A smart attempt at solving select_related for many-to-many relationships in Django. Add a custom manager to your model and call e.g. Entry.objects.all()[:10].batch_select(“tags”) to execute two queries—one pulling back the first ten entries and another using an “IN” query against the tags table to pull back all of the tags for those entries in one go. # 23rd November 2009, 4:19 pm
python-sqlparse (via) Python library for re-identing SQL statements. This could make debugging Django’s generated SQL a whole lot easier. You can try the library out using an App Engine hosted application (complete with an API). # 28th April 2009, 8:25 pm
