'''Dependencies''':
- Django version : 1.9.1
- PostgreSQL version : "PostgreSQL 9.4.4 on x86_64-unknown-linux-gnu,
compiled by gcc (Ubuntu 4.9.1-16ubuntu6) 4.9.1, 64-bit"
- DB conf :
{{{
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'test',
'USER': 'test',
'PASSWORD': 'test',
'HOST': 'localhost',
'PORT': '',
},
}
}}}
'''Following those steps:'''
1 - creating a minimal model example including a DurationField
{{{
class Foo(models.Model):
bar = models.DurationField()
}}}
2 - migrate the new model
{{{
$ python manage.py makemigrations AppName
$ python manage.py migrate
}}}
3 - then check the type of the 'bar' DB column related to the 'bar'
DurationField on the 'appname_foo' generated table
{{{
\d appname_foo
}}}
=> The datatype associated to the bar column is not interval as expected
but float
