Python django组合两个查询集并将其调用为html

我在views.py中有这个queryset，我正在使用union来组合这两个queryset，我如何使用另一个模型（sql中的内部联接）组合这两个queryset并将其调用到html？请检查我特别提供的温度

company = FmCustomerUsers.objects.filter(user=request.user.id)
employee = FmCustomerEmployeeSupplier.objects.filter(
        fmCustomerID__company_name__in=company.values_list('fmCustomerID__company_name'))
feedback = TrEmployeeSuppliersFeedbackQuestionsSubmittedRecords.objects.filter(
        fmCustomerID__company_name__in=company.values_list('fmCustomerID__company_name')).filter(
        fmCustomerEmployeeSupplierID__in=employee.values_list('id')).union(TrCustomerEmployeeSupplierSubmittedRecords.objects.filter(
        fmCustomerID__company_name__in=company.values_list('fmCustomerID__company_name')))

这是我的模特

这是我的html

{% for feedback in feedbacks %}

                    <tr>
                    <td> {{feedback.id}} </td> 
                    <td> {{feedback.inputdate}} </td>
                    <td> {{feedback.fmCustomerEmployeeSupplierID.firstname}} {{feedback.fmCustomerEmployeeSupplierID.middleInitial}} {{feedback.fmCustomerEmployeeSupplierID.lastname}}</td>
                    <td> {{feedback.fmCustomerEmployeeSupplierID.fmCustomerLocationID}} </td>
                    <td> {{feedback.fmCustomerID.fmCustomerLocationID}} </td>
                    <td> {{feedback.fmCustomerEmployeeSupplierID.contactNumber}} </td>
                     <td> {{feedback.fmCustomerID.section}} </td>
                    <td> {{feedback.fmCustomerEmployeeSupplierID.bodyTemperature}} </td> ====> this td is for model `TrCustomerEmployeeSupplierSubmittedRecords`
                    <td>{{feedback.q1Answer}}</td>
                </tr>

不能有两个行数不相同的查询的并集

您正在尝试建立以下联盟：

• t员工供应商反馈问题提交记录（19行）
• TrCustomerEmployeeSupplierSubmittedRecords（12行）

你不能这么做。

---

我所能告诉你的是，你应该只选择你需要在你的最终查询中得到的字段，以便在查询的两边有相同数量的字段。可能使用值列表或仅使用queryset方法。

这并不复杂，错误是不言自明的：

---

每个联合查询必须具有相同的列数

您的代码非常混乱，以至于您没有看到它：

TrCustomerEmployeeSupplierSubmittedRecords

和

tremployeeSuppliers反馈问题SubmittedRecords

不同

看看这个：

FmCustomerEmployeeSupplier中的
联系电话
TrCustomerEmployeeSupplierSubmittedRecords

您的代码应该是：

companys\u name=FmCustomerUsers.objects.filter(
user=request.user.id
).values\u list（'fmCustomerID\u公司名称'）
employees\u id=fmcustomereemployeesupplier.objects.filter(
fmCustomerID\uuuu company\u name\uuuuu in=companys\u name
).values\u列表（“id”）
员工反馈=t员工供应商反馈问题提交记录.objects.filter(
fmCustomerID\uuuu company\u name\uuuuu in=companys\u name，
fmCustomerEmployeeSupplierID\uuuu in=员工id
)
客户反馈=TrCustomerEmployeeSupplierSubmittedRecords.objects.filter(
fmCustomerID\uuuu company\u name\uuuuu in=companys\u name，
fmCustomerEmployeeSupplierID\uuuu in=员工id
)
反馈=员工反馈。工会（客户反馈）

您只需在
employees\u feedback
和
customers\u feedback
上添加一个
values\u列表
，并使用所需的相同字段

您需要遵循PEP8，因为很难读懂您的意思
您能提供一个例子吗？im my model
TremployeeSuppliers反馈问题提交记录
我没有
fmCustomerEmployeeSupplierID
字段每个联合查询必须具有相同的列数第1行：…=U2。“id”）其中U0。“用户id”=2）联合（选择“追踪…所以，你们不能做你们想做的事，概念问题而不是代码问题（创建抽象模型将在这里帮助你们）有没有办法在不创建抽象模型的情况下得到我想要的？说实话，你所有的代码都写得不好，重新开始，合理化它。
FmCustomerEmployeeSupplier
和
TrCustomerEmployeeSupplierSubmittedRecords
都是一样的，没有意义，因为你想要
TrCustomerEmployeeSupplierSubmittedRecords
s

和

t员工供应商反馈问题提交记录

相同
