Question

我想在Django中执行这个MySQL查询：

SELECT Descripcion,count(*)
FROM votaciones.Tarjeton 
WHERE Voto_idVoto=1 
GROUP BY Descripcion;

MySQL的预期结果：

＆＃39;＆＃39;，＆＃39; 1＆＃39;

＆＃39; Camilo Gomez Ortega＆＃39;，＆＃39; 3＆＃39;

＆＃39; JUan Jose Marquez＆＃39;，＆＃39; 3＆＃39;

＆＃39; Pedro Pablo de la Mar＆＃39;，＆＃39; 15＆＃39;

＆＃39; Sandra Mejia Gutierez＆＃39;，＆＃39; 4＆＃39;

我的模特是：

class Tarjeton(models.Model):
idtarjeton = models.AutoField(db_column='idTarjeton', primary_key=True)  # Field name made lowercase.
descripcion = models.CharField(db_column='Descripcion', max_length=45)  # Field name made lowercase.
cadidatos_idcadidatos = models.ForeignKey(Cadidatos, models.DO_NOTHING, db_column='Cadidatos_idCadidatos')  # Field name made lowercase.
voto_candidato = models.ForeignKey('Voto', models.DO_NOTHING, db_column='Voto_idVoto')  # Field name made lowercase.

class Meta:
    managed = False
    db_table = 'Tarjeton'

Answer 1

尝试这种方式：

from django.db.models import Count
Tarjeton.objects.filter(voto_candidato=1).values('descripcion').annotate(Count('descripcion')).order_by()

SELECT COUNT（*）GROUP BY DJANGO如何做？
