BIT(1) Boolean Fields¶
Some database systems, such as the Java Hibernate ORM, don’t use MySQL’s
bool
data type for storing boolean flags and instead use BIT(1)
.
Django’s default BooleanField
and NullBooleanField
classes can’t work
with this.
The following subclasses are boolean fields that work with BIT(1)
columns
that will help when connecting to a legacy database. If you are using
inspectdb
to generate models from the database, use these to replace the
TextField
output for your BIT(1)
columns.
- class Bit1BooleanField¶
A subclass of Django’s
BooleanField
that uses theBIT(1)
column type instead ofbool
.
- class NullBit1BooleanField¶
Note
Django deprecated
NullBooleanField
in version 3.1 and retains it only for use in old migrations.NullBit1BooleanField
is similarly deprecated.A subclass of Django’s
NullBooleanField
that uses theBIT(1)
column type instead ofbool
.
