Python django:filter.values（…）未检索请求的字段

基于以下模型，我尝试通过执行以下筛选来查询BankingDetail并检索帐户和opportunity的信息：

查询：

bankingLST = BankingDetail.objects.filter(opportunity__opportunity_name__icontains = searchItem) | BankingDetail.objects.filter(account__account_name__icontains = searchItem) | BankingDetail.objects.filter(sfAttachmentID__icontains = searchItem) | BankingDetail.objects.filter(opportunity__external_opportunity_id__icontains = searchItem) | BankingDetail.objects.filter(account__external_account_id__icontains = searchItem).values(
    'id',
    'opportunity__external_opportunity_id',
    'account__external_account_id',
    'opportunity__opportunity_name',
    'account__account_name', 
    'account__industry')

型号：

class AccountDetail(models.Model):
    external_account_id = models.CharField(max_length=18, unique = True)
    account_name = models.TextField(unique = False, blank=True, null=True)
    industry = models.CharField(max_length=18, unique = False, blank=True, null=True)
    billing_state = models.CharField(max_length=18, unique = False, blank=True, null=True)
    def __str__(self):
        return self.account_name

class OpportunityDetail(models.Model):
    account = models.ForeignKey(AccountDetail, on_delete=models.CASCADE, related_name='AccountDetails')
    external_opportunity_id = models.CharField(max_length=18, unique = True)
    opportunity_name = models.TextField(unique = False, blank=True, null=True)
    stage_name = models.CharField(max_length=18, unique = False, blank=True, null=True)
    def __str__(self):
        return self.opportunity_name

class BankingDetail(models.Model):
    account = models.ForeignKey(AccountDetail, on_delete=models.CASCADE, related_name='AccountBankingDetails')
    opportunity = models.ForeignKey(OpportunityDetail, on_delete=models.CASCADE, related_name='OpportunityDetails')
    sfAttachmentID = models.CharField(max_length=18, unique = True)
    created = models.DateTimeField(auto_now_add=True)
    def __str__(self):
        return self.account.account_name + ' - (' + self.opportunity.opportunity_name + ')'

目前的答复：

        tmpJson = serializers.serialize("json",bankingLST)
        tmpObj = json.loads(tmpJson)
        print(tmpObj)

[
{
    "model": "app_banking.bankingdetail",
    "pk": 2,
    "fields": {
    "account": 3,
    "opportunity": 2,
    "sfAttachmentID": "175688177w3",
    "created": "2020-07-20T01:55:20.351Z"
    }
},
{
    "model": "app_banking.bankingdetail",
    "pk": 3,
    "fields": {
    "account": 4,
    "opportunity": 3,
    "sfAttachmentID": "1236547898745632x3",
    "created": "2020-07-23T00:08:56.863Z"
    }
}
]

我不明白为什么我指定的字段没有被带回：

• opportunity\u外部\u opportunity\u id
• 账户\外部\账户\ id
• opportunity\u opportunity\u名称
• 账户名称
• 会计行业

但同时也解释了为什么在没有具体说明的情况下，它带回了以下内容：

• 帐目
• 机会
• sfAttachmentID
• 创造
你可以试试这个

from django.db.models import Q 
bankingLST=BankingDetail.objects.filter(Q(opportunity__opportunity_name__icontains=searchItem)|
Q(account__account_name__icontains = searchItem)|
Q(sfAttachmentID__icontains = searchItem)|
Q(opportunity__external_opportunity_id__icontains = searchItem)
|Q(account__external_account_id__icontains = searchItem)).values(
    'id', 'opportunity__external_opportunity_id',
    'account__external_account_id',
    'opportunity__opportunity_name',
    'account__account_name', 
    'account__industry')

从django.db.models导入Q
bankingLST=BankingDetail.objects.filter（Q（opportunity\uuuuuOpportunity\uName\uuuuuiContains=searchItem）|
Q（帐户名称=搜索项）|
Q（sfAttachmentID\uuu icontains=searchItem）|
Q（机会\外部\机会\ id \ icontains=searchItem）
|Q（账户\外部\账户\ id \ icontains=searchItem））.值(
'id'、'opportunity\u外部\u opportunity\u id'，
“账户外部账户id”，
“opportunity\u opportunity\u name”，
“账户名称”，
"会计行业")
该数据是如何生成的？它将返回模型上的所有字段moment@IainShelvington，问题中的当前响应是执行以下操作的结果：tmpJson=serializers.serialize（“json”，bankingLST）tmpObj=json.loads（tmpJson）将序列化程序和用于调用它的代码添加到question@IainShelvington对不起，我不明白你的请求，你知道我用什么代码生成JSON吗？如果这是正确的，我在前面的评论中添加了，但为了以防万一，我也在当前回答下面的问题中添加了：您正在使用
django.core.serializers
？如果您想要一些复杂的序列化，我建议使用类似于
djangorestframework
的东西，也许内置的
json
包就可以了，尽管我遇到了错误：“dict”对象没有属性“\u meta”
