在我的 django 应用程序中,我创建了一个这样的模型:
class Plan_miesieczny_aktualny(models.Model):
id = models.CharField(max_length=30, primary_key=True)
pozycja_planu = models.ForeignKey('Pozycje_planu', to_field='id')
miesiac = models.IntegerField
liczba = models.DecimalField
cena = models.DecimalField
pakiet = models.ForeignKey('Pakiet', to_field='id')
kod_grupy = models.IntegerField(null=True)
但最初的迁移已经产生了:
migrations.CreateModel(
name='Plan_miesieczny_aktualny',
fields=[
('id', models.CharField(max_length=30, primary_key=True, serialize=False)),
('kod_grupy', models.IntegerField(null=True)),
('pakiet', models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='nfz_umx.Pakiet')),
],
),
....
migrations.AddField(
model_name='plan_miesieczny_aktualny',
name='pozycja_planu',
field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='nfz_umx.Pozycje_planu'),
),
为什么缺少某些字段?
