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
- quarter
- time
- hour
- minute
- second
- isnull
- regex
- iregex
Protip: Use in to avoid chaining filter() and exclude()
