Hi David, thanks for your help. I tried setting dim to 4 but did't see any change.
Here is my model: ```python from django.contrib.gis.db import models class Kmsys(models.Model): # Define constants ---------------------------- EPSG_CODE = 31287 NAME_OF_GEOMETRY_FIELD = "geom" # F I E L D S ------------------------------------------------- id = models.IntegerField(primary_key=True) geom = models.MultiLineStringField( dim=4, srid=EPSG_CODE, blank=True, null=True, spatial_index=True ) # EPSG:31287=AustriaLambert object_id = models.BigIntegerField(db_column="OBJECTID", unique=True) code = models.CharField(max_length=80, db_column="KMSYS_CODE", unique=False) name = models.CharField(max_length=500, db_column="KMSYS_BEZEICHNUNG", unique=False) start_date = models.DateTimeField(db_column="KMSYS_START_DATUM") end_date = models.DateTimeField(db_column="KMSYS_ENDE_DATUM") len = models.FloatField(db_column="LEN") km_from = models.FloatField(db_column="KMSYS_KMVON") km_till = models.FloatField(db_column="KMSYS_KMBIS") parts_quantity = models.IntegerField(db_column="TEILE_ANZ") fme_date = models.DateTimeField(db_column="FME_DATUM") se_anno_cad_data = models.FileField(db_column="SE_ANNO_CAD_DATA") bauk_id = models.FloatField(db_column="BAUK_ID") # Meta-Class ------------------------------------------------------ class Meta: managed = False db_table = "KMSYS" # db_table = '"public"."KMSYS"' verbose_name = "Kmsys" verbose_name_plural = "Kmsys" ordering = ["code"] # Methods --------------------------------------------------------- def __str__(self) -> str: """String for representing the Model object.""" return f"{self.code} | {self.name} | {self.start_date} | {self.end_date} | { self.km_from} | {self.km_till} | {self.parts_quantity} | {self.fme_date} | { self.se_anno_cad_data} | {self.bauk_id}" ``` And this is the pytest that keeps failing -> At the beginning i just tested the dim=3 manually without db-access from django.contrib.gis.geos import GEOSGeometry, LineString, MultiLineString, Point from rest_framework.reverse import reverse import logging import pytest from kmsys.models import Kmsys from kmsys.test.test_runner import DjangoNoCreateAndDropRunner logger = logging.getLogger(__name__) # use pytest marks to tell pytest-django your test needs database access!
