I am trying to create a PostgreSQL check constraint on an
`IntegerRangeField`, but when I run `makemigrations` I get the following
error:
{{{
ValueError: Cannot serialize: Range(1, 10000, '[)')
There are some values Django cannot serialize into migration files.
}}}
Here's a simple example of my model which raises the error:
{{{
from django.contrib.postgres.fields import IntegerRangeField
from django.db.backends.postgresql.psycopg_any import NumericRange
from django.db import models
from django.db.models.constraints import CheckConstraint
from django.db.models.expressions import Q
class MyModel(models.Model):
price_range = IntegerRangeField()
class Meta:
constraints = [
CheckConstraint(
check=Q(price_range__contained_by=NumericRange(1, 10000)),
name="price_range_gt_1_and_lte_10000",
)
]
}}}
Judging by the following ticket this should work, so any help would be
welcome:
