-------------------------------------+-------------------------------------
After upgrading to Django 2.1, we have system checks failing due to
`admin.E108` `SystemCheckError`. This behavior was not present in Django
2.0.8. I don't see any relevant API change documented in the 2.1 Release
notes, therefore I'm filling this as a bug.
The error:
{{{
<class 'automation.admin.TriggerAdmin'>: (admin.E108) The value of
'list_display[3]' refers to 'position', which is not a callable, an
attribute of 'TriggerAdmin', or an attribute or method on
'automation.Trigger'.
}}}
The `automation.admin.TriggerAdmin` class:
{{{
from django.contrib import admin
from automation.models import Trigger
@admin.register(Trigger)
class TriggerAdmin(admin.ModelAdmin):
model = Trigger
list_display = ('company', 'trigger_type', 'action_type', 'position')
list_filter = ('company', 'trigger_type', 'action_type')
}}}
The `automation.models.Trigger` model (abbreviated):
{{{
from django.db import models
from core.fields import PositionField
class Trigger(models.Model):
position = PositionField(
verbose_name=_('Priority'),
collection='company'
)
(...)
}}}
The `core.fields.PositionField` field (abbreviated, originally taken from
the `django-positions` package):
{{{
from django.db import models
class PositionField(models.IntegerField):
(...)
}}}
