how to select more options in “ManyToManyField()”?

i wanted to create a tag option for a a music model , well mainly musics accept more than one tag and there are amny kind of genres and tags ,so i wanted to make a ManyToManyField() that you can set more than 1 value ,also if you tag is not in add it in. to do that i thought maybe can make another CharField() then adding it to tag_name :

    #posts model
    name = models.CharField(max_length=200)
    band = models.CharField(max_length=200)
    release = models.DateTimeField()
    tag_add = models.CharField(max_length=100)
    tags = models.ManyToManyField(Tags)
    #cover = models.ImageField(upload_to='media/image')
    #file = models.FileField(upload_to='media/audio')

    class Meta(self):
        ordering = ['release']

    def __str__(self):
        return self.name 

    def get_absolute_url(self):
        return reverse('pages:music_detail',args=[str(self.id)])

class Tags(models.Model):
    tag_name = models.CharField(max_length=100)

but i stuck here too ,i really dont know how to add a models field data to another models field ? i would appreciate if you guide me here

Answer

For a user to select more than one tag, they simply have to ctrl then click on the tags. For Android I suppose it’s long-pressing. For adding a tag if it’s not in the models, you don’t need a field for that. In the admin, you can just click on the + sign.
