python manage.py makemigrations django不'；不要创建所有字段

当我执行

python manage.py makemigrations

django没有为

Todo

模型创建所有字段时，我有一个问题，请帮助解决这里的问题

class Todo(models.Model):
     task = models.CharField(max_length=255)
     title = models.CharField(max_length=100),
     _date = models.CharField(max_length=100),
     categories = models.CharField(max_length=100),
     keywords = models.CharField(max_length=100),
     summary = models.TextField(),
     description = models.TextField()

迁移模型

class Migration(migrations.Migration):

initial = True

dependencies = [
]

operations = [
    migrations.CreateModel(
        name='Todo',
        fields=[
            ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
            ('task', models.CharField(max_length=255)),
            ('description', models.TextField()),
        ],
    ),
]

删除后面的逗号。通过在末尾添加逗号，可以将该项包装在一个单元组中。删除尾部的逗号。通过在末尾添加逗号，可以将该项包装在一个单元组中。
