我正尝试显示与外国相关的字段，就像这个例子一样，它起作用了
{
"reqid": 10,
"reqdate": "2022-12-05",
"reqdescription": "Aircon Not working",
"officerequestor": "OVCAA ",
"officeid": "PPD ",
"inspection": {
"insdate": "2022-12-06",
"diagnosis": "need to buy prism",
"inspector": "EMP-322 "
}
},这是我的serializers.py
class RequestAdditionDetailsSerializer(serializers.ModelSerializer):
class Meta:
model = Inspection
fields = ['insdate',
'diagnosis',
'inspector'
]
class RequestorSerializer(serializers.ModelSerializer):
inspection = RequestAdditionDetailsSerializer(read_only=True)
class Meta:
model = Request
fields = ['reqid',
'reqdate',
'reqdescription',
'officerequestor',
'officeid',
'inspection'
]我的问题是我能不能换个方式
{
"inspectid": 5,
"reqid": "10",
"insdate": "2022-12-06",
"diagnosis": "need to buy prism",
"inspector": "EMP-322",
"isinspected": {
"reqdescription": "Aircon Not working",
"reqdate": "2022-12-05",
"officerequestor": "OVCAA"
}
},这是我已经尝试过的，tbh我不认为这将工作有一个解决这个问题的办法。
如果没有，我可能会添加额外的检查列，如reqdescription、reqdate等。只是为了显示它们
class InspectionAdditionalDetailsViewSerializer(serializers.ModelSerializer):
class Meta:
model = Request
fields = ['reqdescription',
'reqdate',
'officerequestor'
]
class InspectionSerializer(serializers.ModelSerializer):
request_details = InspectionAdditionalDetailsViewSerializer(read_only=True)
class Meta:
model = Inspection
fields = ['inspectid',
'reqid',
'insdate',
'diagnosis',
'inspector',
'isinspected',
'request_details'
]这是我的models.py
class Inspection(models.Model):
inspectid = models.AutoField(primary_key=True)
reqid = models.OneToOneField('Request', models.DO_NOTHING, db_column='reqid', blank=True, null=True)
class Meta:
managed = False
db_table = 'inspection'
class Request(models.Model):
reqid = models.AutoField(primary_key=True)
class Meta:
managed = False
db_table = 'request'

您已经定义了
OneToOne字段名reqid，因此应将其用作序列化程序键。注意到Django会将
_id添加到字段中，这样它在数据库中就会变成reqid_id，最好将其命名为req或request，只是为了引用相关对象。
