I can't create foreign keys: Invalid field names even though they exist

Hi I am simply trying to create an object for Table2 with a foreign key to Table1.

Here are my models:

class Table1(models.Model):
    id = models.IntegerField(primary_key=True)
    name = models.TextField()

    class Meta:
        managed = False
        db_table = 'table1'

class Table2(models.Model):
    id = models.IntegerField(primary_key=True)
    date = models.DateField()
    home_team = models.ForeignKey('Table1', models.DO_NOTHING, blank=True, null=True)
    away_team = models.ForeignKey('Table1', models.DO_NOTHING, related_name='games_away_team_set', blank=True, null=True)

    class Meta:
        managed = False
        db_table = 'table2'

The foreign key fields are clearly defined but when I try to create a new table2 object, I can’t seem to access the field. For example, I have a data migration file that uses RunPython() to populate my database using a JSON file, with predefined keys. Here is the relevant code:
(Games is the table2 object)

 with open(games_json_path, 'r') as f:
        games = json.load(f)
        for game in games:
            #Create a game
            g = Games.objects.create(id=game['id'], date=game['date'], home_team=game['homeTeam']['id'], away_team=game['awayTeam']['id'])

Here, I try to use the pk for the table1 object, directly from the JSON data. However, even if I try to look up the instance and define the foreign key that way, I still get the same error when trying to run this migration.

Here is the error: “TypeError: Games() got unexpected keyword arguments: ‘home_team’, ‘away_team’”

I’ve gone into the shell and made sure my Game has the correct fields:

 Get the list of field names in the Games model
   ...: field_names = [field.name for field in Games._meta.fields]
   ...: print(field_names)

which outputs: [‘id’, ‘date’, ‘home_team’, ‘away_team’]

No matter what I do, I can’t seem to access these fields and correctly create a Game object.
Any help would be much appreciated.

You don’t show a model here named Games - your model that you’re trying to create an instance of is Table2.
