Package: manik-django-sql-explorer-test
Django SQL ExplorerDjango SQL Explorer is inspired by any number of great query and reporting tools out there.The original idea came from Stack Exchange’sData Explorer, but also owes credit to similar projects likeRedashandBlazer.SQL Explorer wants to make the flow of data between people 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!The product & design principles are: simplicity, intuitive use, unobtrusiveness, stability, and being unsurprising.django-sql-explorer is MIT licensed, and pull requests are welcome.A view of a queryViewing all queriesQuick access to DB schema infoSnapshot query results to S3 & download as csvFeaturesSecurityLet’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! It’s recommended you use the EXPLORER_CONNECTION_NAME setting to connect SQL Explorer to a read-only database role.Explorer supports two different permission checks for users of the tool. Users passing the EXPLORER_PERMISSION_CHANGE test can create, edit, delete, and execute queries. Users who do not pass this test but pass the EXPLORER_PERMISSION_VIEW test can only execute queries. Other users cannot access any part of Explorer. Both permission groups are set to is_staff by default and can be overridden in your settings file.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 startedBuilt on Django’s ORM, so works with Postgresql, Mysql, and Sqlite.Small number of dependencies.Just want to get in and write some ad-hoc queries? Go nuts with the Playground area.newSnapshotsTick the ‘snapshot’ box on a query, and Explorer will upload a .csv snapshot of the query results to S3. Configure the snapshot frequency via a celery cron task, e.g. for daily at 1am:'explorer.tasks.snapshot_queries':{'task':'explorer.tasks.snapshot_queries','schedule':crontab(hour=1,minute=0)}Requires celery, obviously. Also uses djcelery and tinys3. All of these deps are optional and can be installed withpip install -r optional-requirements.txtThe checkbox for opting a query into a snapshot is ALL THE WAY on the bottom of the query view (underneath the restults table).Email query resultsClick the email icon in the query listing view, enter an email address, and the query results (zipped .csv) will be sent to you.Parameterized QueriesUse $$foo$$ 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 colleaguesUse $$paramName:defaultValue$$ to provide default values for the parameters.Schema Helper/explorer/schema/ renders a list of your Django apps’ table and column names + types that you can refer to while writing queries. Apps can be excluded from this list so users aren’t bogged down with tons of irrelevant tables. See settings documentation below for details.This is available quickly as a sidebar helper while composing queries (see screenshot)Supports many_to_many relations as well.Quick search for the tables/django models you are looking for. Just start typing!Template ColumnsLet’s say you have a query like ‘select id, email from user’ and you’d like to quickly drill through to the profile page for each user in the result. You can create a “template” column to do just that.Just set up a template column in your settings file:EXPLORER_TRANSFORMS =[('user','<ahref="https://yoursite.com/profile/{0}/">{0}</a>')]And change your query to ‘SELECT id AS “user”, email FROM user’. Explorer will match the “user” column alias to the transform and merge each cell in that column into the template string. Cool!Pivot TableGo to the Pivot tab on query results to use the in-browser pivot functionality (provided by Pivottable JS).Hit the link icon on the top right to get a URL to recreate the exact pivot setup to share with colleagues.Query LogsExplorer will save a snapshot of every query you execute so you can recover lost ad-hoc queries, and see what you’ve been querying.This also serves as cheap-and-dirty versioning of Queries, and provides the ‘run count’ property and average duration in milliseconds, by aggregating the logs.You can also quickly share playground queries by copying the link to the playground’s query log record – look on the top right of the sql editor for the link icon.If Explorer gets a lot of use, the logs can get beefy. explorer.tasks contains the ‘truncate_querylogs’ task that will remove log entries older than <days> (30 days and older in the example below).'explorer.tasks.truncate_querylogs':{'task':'explorer.tasks.truncate_querylogs','schedule':crontab(hour=1,minute=0),'kwargs':{'days':30}}Stable95% according to coverage…for what that’s worth. Just install factory_boy and runpython manage.py test explorer.tests –settings=explorer.tests.settingsBattle-tested in production every day by the ePantry team.Power tipsOn the query listing page, focus gets set to a search box so you can just navigate to /explorer and start typing the name of your query to find it.Quick search also works after hitting “Show Schema” on a query view.Command+Enter and Ctrl+Enter will execute a query when typing in the SQL editor area.Hit the “Format” button to format and clean up your SQL (this is non-validating – just formatting).Use the Query Logs feature to share one-time queries that aren’t worth creating a persistent query for. Just run your SQL in the playground, then navigate to /logs and share the link (e.g. /explorer/play/?querylog_id=2428)If you need to download a query as something other than csv but don’t want to globally change delimiters via settings.EXPLORER_CSV_DELIMETER, you can use /query/download?delim=| to get a pipe (or whatever) delimited file. For a tab-delimited file, use delim=tab. Note that the file extension will remain .csvIf a query is taking a long time to run (perhaps timing out) and you want to get in there to optimize it, go to /query/123/?show=0. You’ll see the normal query detail page, but the query won’t execute.Set env vars for EXPLORER_TOKEN_AUTH_ENABLED=TRUE and EXPLORER_TOKEN=<SOME TOKEN> and you have an instant data API. Just:curl--header"X-API-TOKEN:<TOKEN>"https://www.your-site.com/explorer/<QUERY_ID>/csvInstallRequires Python 2.7, 3.4, or 3.5. Requires Django 1.7.1 or higher.Install with pip from github:pip installdjango-sql-explorerAdd to your installed_apps:INSTALLED_APPS = (...,'explorer', ... )Add the following to your urls.py (all Explorer URLs are restricted to staff only per default):url(r'^explorer/',include('explorer.urls')),Run syncdb to create the tables:python manage.py syncdbYou can now browse tohttps://yoursite/explorer/and get exploring! However note it is highly recommended that you also configure Explorer to use a read-only database connection via the EXPLORER_CONNECTION_NAME setting.DependenciesAn effort has been made to keep the number of dependencies to a minimum.Back EndNameVersionLicensesqlparse0.1.18BSDFactory Boy2.6.0MITunicodecsv0.14.1BSDsqlparse is Used for SQL formatting onlyFactory Boy is only required for testsunicodecsv is used for CSV generationFront EndNameVersionLicenseTwitter Boostrap3.3.6MITjQuery2.1.4MITjQuery Cookie1.4.1MITUnderscore1.7.0MITCodemirror5.11.0MITfloatThead1.2.8MITlist.js1.1.1MITpivottable.js2.0.0MITTestsFactory Boy is needed if you’d like to run the tests, which can you do easily:python manage.py test--settings=explorer.tests.settingsand with coverage:coverage run--source='.'manage.py test--settings=explorer.tests.settingsthen:coverage report…95%!
