我是Django和Django-REST的新手,所以请耐心等待.也许答案在文档中,所以如果我错过了,请提前道歉.

目标:我想创建一个EquipmentInfo对象,其属性包括预先存在的外键(EquipmentType和EquipmentManufacturer).

models.py

class EquipmentType(models.Model):
    equipment_type = models.CharField(verbose_name="Equipment Type", max_length=50, unique=True)

    def __unicode__(self):
        return self.equipment_type


class EquipmentManufacturer(models.Model):

    manufacturer_name = models.CharField(verbose_name="Manufacturer Name", max_length=50, unique=True)

    def __unicode__(self):
        return self.manufacturer_name


class EquipmentInfo(models.Model):

    equipment_type = models.ForeignKey(EquipmentType, verbose_name="Equipment Type")
    part_identifier = models.CharField(verbose_name="Machine ID (alias)", max_length=25)
    manufacturer_name = models.ForeignKey(EquipmentManufacturer, verbose_name="Manufacturer Name")
    serial_number = models.CharField(verbose_name="Serial Number", max_length=25)
    date_of_manufacture = models.DateField(verbose_name="Date of Manufacture", default=date.today)
    is_active = models.BooleanField(verbose_name="Is Active", default=True)

    def __unicode__(self):
        return self.part_identifier

serializers.py

class EquipmentTypeSerializer(serializers.ModelSerializer):
    class Meta:
        model = EquipmentType
        fields = ('id', 'equipment_type',)

class EquipmentManufacturerSerializer(serializers.ModelSerializer): …
