我从 Django 开始。我有 3 个模型,一个父类“Cliente”和两个子类“Persona”和“Empresa”。模型.py
class Cliente(models.Model):
idcliente = models.AutoField(unique=True, primary_key=True)
direccion = models.CharField(max_length=45L, blank=True)
telefono = models.CharField(max_length=45L, blank=True)
email = models.CharField(max_length=45L, blank=True)
def __unicode__(self):
return u'Id: %s' % (self.idcliente)
class Meta:
db_table = 'cliente'
class Empresa(models.Model):
idcliente = models.ForeignKey('Cliente', db_column='idcliente', primary_key=True)
cuit = models.CharField(max_length=45L)
nombre = models.CharField(max_length=60L)
numero_ingresos_brutos = models.CharField(max_length=45L, blank=True)
razon_social = models.CharField(max_length=45L, blank=True)
def __unicode__(self):
return u'CUIT: %s - Nombre: %s' % (self.cuit, self.nombre)
class Meta:
db_table = 'empresa'
class Persona(models.Model):
idcliente = models.ForeignKey('Cliente', db_column='idcliente', primary_key=True)
representante_de = models.ForeignKey('Empresa', null=True, db_column='representante_de', blank=True, related_name='representa_a')
nombre = models.CharField(max_length=45L)
apellido = models.CharField(max_length=45L)
def __unicode__(self):
return u'Id: %s - Nombre completo: %s %s' % (self.idcliente, self.nombre, self.apellido)
class Meta:
db_table = 'persona'
我想在同一个视图中管理一个类及其父级。我想以相同的形式添加、编辑和删除“Cliente”和“Persona”/“Cliente”。你能帮助我吗?
