Django makemigrations omits some fields from model

In my django app I've created a model like that:

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)


But initial makemigrations has produced that:

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'),
),


Why some fields are missing?

Answer Source

You should always declare fields calling fields class constructor:

miesiac = models.IntegerField()
liczba = models.DecimalField(max_digits=5, decimal_places=2)
cena = models.DecimalField(max_digits=5, decimal_places=2)
