Akukho ukuziphatha okuchaziwe kwesihlungi se-%22DO_NOTHING%22 ku-Django. Lokhu kungaholela emiphumeleni engalindelekile uma isetshenziswe kusifanekiso noma ekubukeni.
.db.utils.ProgrammingError: %22DO_NOTHING%22 is not defined
I'm trying to run a migration in Django, but I get the following error:
<code>django.db.utils.ProgrammingError: %22DO_NOTHING%22 is not defined</code>
The migration file looks like this:
<code># -*- coding: utf-8 -*-
# Generated by Django 1.11 on 2017-08-18 13:16
from __future__ import unicode_literals
from django.db import migrations, models
class Migration(migrations.Migration):
dependencies = [("myapp", "0004_auto_20170818_1255")]
operations = [migrations.AlterField(model_name="mymodel", name="field1", field=models.ForeignKey(null=True, on_delete=models.DO_NOTHING, related_name="+", to="myapp"))] # noqa</code>
The model it's referring to looks like this (the field in question is <code>field1</code>) :
<code>class MyModel(models.Model):
field1 = models.... # other fields here</code> # noqa
Iphutha lithi i DO_NOTHING inketho ayichazwanga - lokhu kungenzeka ngoba ayisekelwe enguqulweni ye-Django oyisebenzisayo. Ukuze ulungise lokhu, ungabuyekeza i-Django ibe yinguqulo entsha, noma uguqule ifayela le- on_delete inketho kokunye okusekelwe.
Ukuxazulula i-Django 'Handler' ayichazwanga
Leli phutha lidalwe isitatimende sokungenisa esingekho kuphrojekthi yakho ye-Django. Ungalungisa lokhu ngokwengeza umugqa olandelayo esigabeni sokungeniswa kwephrojekthi yakho:
kusuka ku-django.contrib.auth.models ngenisa Umsebenzisi
Uma usebenzisa ilabhulali yokuqinisekisa yenkampani yangaphandle, ungase udinge ukungeza nokungenisa kwayo.
