Current Django Version: 5.0
Mandatory impostor syndrome notice: The documentation has gotten a lot easier to navigate and this cheatsheet makes a lot less sense nowadays, but many people seem to be actively using it, so i'll keep it updated for a few more versions.

Field lookups (link)
Field lookups are how you specify the meat of an SQL WHERE clause. They’re specified as keyword arguments to the QuerySet methods filter(), exclude() and get().
Example: Entry.objects.get(id__exact=14) # note double underscore.- exact
- iexact
- contains
- icontains
- in
- gt
- gte
- lt
- lte
- startswith
- istartswith
- endswith
- iendswith
- range
- date
- year
- iso_year
- month
- day
- week
- week_day
- iso_week_day
- quarter
- time
- hour
- minute
- second
- isnull
- regex
- iregex
Protip: Use in to avoid chaining filter() and exclude()
