DRF序列化程序不显示默认HTML表单页API中的字段(外键和many2many)。字段在GET中可用
DRF序列化程序不显示默认HTML表单页API中的字段(外键和many2many)。字段在GET中可用
提问于 2020-02-26 07:51:27
DRF序列化程序包含一个组和清单字段，它们是many2many和外键。它在默认DRF HTML表单中缺失，但在GET view中可用。目前，串行化器中开启了深度字段。如果我要删除深度，那么外键在默认的超文本标记语言表单中是可用的，但仍然缺少组many2many字段。我需要这两个字段后调用或在DRF HTML的形式。
我是否必须写一些create方法，但我不想为外键和many2many创建新的记录，只想利用现有的字段。
我的序列化程序类。
class MainHostSerializer(serializers.ModelSerializer):
class Meta:
model = MainHost
fields = (
'host_id',
'host_name',
'inventory',
'group'
)
# depth = 2 默认DRF HTML表单的原始视图
{
"host_id": null,
"host_name": ""
}模型类
class MainHost(models.Model):
host_id = models.IntegerField(verbose_name='HOST ID', primary_key=True)
host_name = models.CharField(verbose_name='HOST NAME', max_length=512)
inventory = models.ForeignKey(related_name='inv_ins', on_delete=models.SET_NULL, to='hosts.MainInventory', blank=True, null=True)
group = models.ManyToManyField(MainGroup, related_name='hostgroups', through ='HostGroup')回答 2

MainHost序列化程序的Create方法
def create(self, validated_data):
inv_data = validated_data.pop('inventory')
inv_res = MainInventory.objects.create(**inv_data)
group_data = validated_data.pop('group')
host_data = MainHost.objects.create(inventory = inv_res, **validated_data)
for g_data in group_data:
inv_data = g_data.pop('inv_id')
inv = MainInventory.objects.create(**inv_data)
group_res = MainGroup.objects.create(inv_id = inv, **g_data)
print(validated_data)
HostGroup.objects.create(host = host_data, group = group_res)Stack Overflow用户
