Field Lookups - range


Example

Get all records where id is between 2 and 4:

mydata = Members.objects.filter(id__range=(2, 4)).values()
Run Example »

Definition and Usage

The range lookup is used to get records that are between two values.

The field can be of any type, numeric string or dates.

Example

Get all records where firstname is alphanumeric between 'G' and 'M':

mydata = Members.objects.filter(firstname__range=('G', 'M')).values()
Run Example »

Note: When searching in text fields, remember that 'G' has a lower alphanumeric value than 'g'.


SQL Equivalent

The SQL equivalent to the two example above will be:

WHERE id BETWEEN 2 AND 4;
WHERE id BETWEEN 'G' AND 'M';

All Field lookup keywords must be specified with the fieldname, followed by two(!) underscore characters __ and the keyword:

fieldname__range=value
