demo里的两处index_together报错

https://github.com/Deali-Axy/DjangoStarter/blob/5fff83bb5201e17f6d8728de887d9117cf908032/src/apps/demo/models.py#L41
demo里的两处index_together会报错：

TypeError: 'class Meta' got invalid attribute(s): index_together

DeepSeek提示：

from django.db import models

class MyModel(models.Model):
    field1 = models.CharField(max_length=100)
    field2 = models.IntegerField()

    class Meta:
        # 旧方式（Django <3.1）❌
        # index_together = [['field1', 'field2']]
        
        # 新方式（Django 3.1+）✅
        indexes = [
            models.Index(fields=['field1', 'field2']),
        ]

修改后工作正常，Windows 10平台，Django 5.2

感谢指出，我目前使用的python3.11和django5.0还没遇到这个报错，官方文档确实建议使用新的方式指定索引了。欢迎提pr

            'unique_together': {('name', 'name')},
            'index_together': {('name', 'name')},

这个地方name重复了，提示 django.db.utils.OperationalError: (1060, "Duplicate column name 'name'")

在windows python 3.11 中，會碰到 django.db.utils.OperationalError: (1060, "Duplicate column name 'name'")
在linux(deepin) python 3.12 中 不會碰到

demo 的 models 确实有问题，最新的 commit 已经修复了，如果本地有问题，也可以替换为以下代码

from django.db import models
from django_starter.db.models import ModelExt


# Create your models here.
class Movie(ModelExt):
    title = models.CharField(max_length=100)
    description = models.TextField()
    year = models.IntegerField()
    rating = models.IntegerField()
    genre = models.CharField(max_length=100)
    director = models.CharField(max_length=100)
    actors = models.CharField(max_length=100)

    def __str__(self):
        return self.title

    class Meta:
        db_table = 'demo_movie'
        ordering = ['title']
        verbose_name = '电影'
        verbose_name_plural = verbose_name
        unique_together = (('title', 'year'),)
        indexes = [
            models.Index(fields=["title", "year"]),
        ]


class Actor(ModelExt):
    name = models.CharField(max_length=100)
    birth_date = models.DateField()
    country = models.CharField(max_length=100)
    city = models.CharField(max_length=100)

    def __str__(self):
        return self.name

    class Meta:
        db_table = 'demo_actor'
        ordering = ['name']
        verbose_name = '演员'
        verbose_name_plural = verbose_name


class MusicAlbum(ModelExt):
    name = models.CharField(max_length=100)
    year = models.IntegerField()

    def __str__(self):
        return self.name

    class Meta:
        db_table = 'demo_music_album'
        ordering = ['name']
        verbose_name = '音乐专辑'
        verbose_name_plural = verbose_name


class Music(ModelExt):
    name = models.CharField(max_length=100)
    singer = models.CharField(max_length=100)
    genre = models.CharField(max_length=100)
    rating = models.IntegerField()
    album = models.ForeignKey('MusicAlbum', on_delete=models.CASCADE)

    def __str__(self):
        return self.name

    class Meta:
        db_table = 'demo_music'
        ordering = ['name']
        verbose_name = '音乐'
        verbose_name_plural = verbose_name
