A pluggable app that allows admins to execute SQL and view and export the results. Inspired by Stack Exchange Data Explorer.
Django SQL Explorer
Django SQL Explorer is inspired by Stack Exchange’s [Data Explorer](http://data.stackexchange.com/stackoverflow/queries) and is designed to make the flow of data between people in your company fast, simple, and confusion-free. Quickly write and share SQL queries in a clean, usable query builder, preview the results in the browser, share links to download CSV files, and keep the information flowing baby!
django-sql-explorer is MIT licensed, and pull requests are welcome!
A view of a query
Viewing all queries
Queries can accept parameters. Neato!
Quick access to DB schema info
- Safety & Security
- Let’s not kid ourselves - this tool is all about giving people access to running SQL in production. So if that makes you nervous (and it should) - you’ve been warned. Explorer makes an effort to not allow terrible things to happen, but be careful! Note there is a setting in the tip (master) to use a different SQL connection than the default django connection. It’s recommended you use a read-only database role.
- Admins-only. Nice try randos! You have to pass the is_staff() test to access explorer.
- Enforces a SQL blacklist so destructive queries don’t get executed (delete, drop, alter, update etc). This is not bulletproof and it’s recommended that you instead configure a read-only database role, but when not possible the blacklist provides reasonable protection.
- Easy to get started
- 100% built on Django’s ORM, so works with Postgresql, Mysql, and Sqlite.
- Zero dependencies other than Django and front-end libraries. More detail below.
- Just want to get in and write some ad-hoc queries? Go nuts with the Playground area.
- Looks Reasonably Not Crappy
- Thanks to CodeMirror and Bootstrap you might actually enjoy this for querying more than pgadmin or phpmyadmin
- Parameterized Queries
- Use $$foo$$ in your queries and Explorer will build a UI to fill out parameters. When viewing a query like ‘SELECT * FROM table WHERE id=$$id$$’, Explorer will generate UI for the ‘id’ parameter.
- Parameters are stashed in the URL, so you can share links to parameterized queries with colleagues
- Schema Helper
- /explorer/schema/ renders a list of your Django apps’ table and column names that you can refer to while writing queries. Apps are excludable from this list so users aren’t bogged down in tons of irrelevant tables. See settings documentation below for details.
- This is available quickly as a sidebar helper while composing queries (see screenshot)
- Note there is an open issue that the schema explorer does not show join tables for m2m relations. It’s a work in progres…
- Django Admin Support
- Download multiple queries at once as a zip file through Django’s admin interface via a built-in admin action.
- Meaningful Test Coverage
- 95% according to coverage…for what that’s worth
- You can run them yourself! Just install factory_boy and run “manage.py test”
Requires Python 2.7. No Python 3 support…yet.
This has been tested only with Django 1.6, however it should work back to 1.4. Please report an issue if you encounter problems on earlier versions of Django.
Install with pip from github:
pip install django-sql-explorer
Add to your installed_apps:
INSTALLED_APPS = ( ..., 'explorer', ... )
Add the following to your urls.py (all Explorer URLs are restricted to staff only):
Run syncdb to create the tables (well…just one table really):
python manage.py syncdb
Browse to https://yoursite/explorer/ and get exploring!
An effort has been made to require no packages other than Django. However a number of front-end dependencies do exist and are documented below. All front-end dependencies are served from CDNJS.com
|floatThead *||1.2.0||Creative Commons|
* Embedded and minified locally because this is not available on cdnjs
Factory Boy is needed if you’d like to run the tests, which can you do easily:
python manage.py test
and with coverage:
coverage run --source='.' manage.py test explorer
