如何设置命令以通过txt文件DJANGO填充DJANGO数据

Question

感谢您抽出宝贵时间接受采访：我得到了一个模型，它必须填充3个txt文档，每个文档有40行。该命令应打开每个取行，设置对象，保存它，然后在40范围内再次调用：我能够调用它40次，尽管我40个正在使用相同的最后一行，我如何在txt文件上设置计数以在再次调用时转到下一行？我应该设置一个分割来获取行作为列表吗？并像列表索引一样设置行？list[counter]models.py：class MP4 (models.Model):    nome = models.CharField(blank=True, max_length=100)    url = models.URLField(blank=True, max_length=300)    imagem = models.ImageField(blank=True, upload_to='')    artista = models.CharField(blank=True, max_length=100, default='Unknown')seeder.py（命令）：class Command(BaseCommand):    file_name = ['nome.txt', 'artista.txt', 'url.txt']    @classmethod    def handle(cls, *args, **kwargs):        counter = 0        for row in range(40):            counter += 1             with open(cls.file_name[0]) as file:                for linha in file:                    nome = linha            with open(cls.file_name[1]) as file:                for linha in file:                    artista = linha            with open(cls.file_name[2]) as file:                for linha in file:                    url = linha            row = MP4(                nome=nome,                url=url,                artista=artista,                id=MP4.objects.latest('id').id + 1                )            row.save()名词.txt：Somewhere over the Rainbowocean driveMichael Jackson - Billie Jean ( cover by J.Fla )...网址.txt：https://www.youtube.com/watch?v=V1bFr2SWP1I&list=RDV1bFr2SWP1I&start_radio=1https://www.youtube.com/watch?v=KDxJlW6cxRk&list=RDVHoT4N43jK8&index=19https://www.youtube.com/watch?v=J1AdPY73qxo...艺术家.txtgordinho havaianoduke dumontMichael Jackson...

Answer 1

我想你可以一起打开所有3个文件，并用zip循环它。

file_name = ['nome.txt', 'artista.txt', 'url.txt']

with open(file_name[0]) as file1, open(file_name[1]) as file2, open(file_name[2]) as file3:

    for data in zip(file1, file2, file3):

        nome, artista, url = data

         row = MP4(

            nome=nome,

            url=url,

            artista=artista,

            id=MP4.objects.latest('id').id + 1

            )

        row.save()
