在 Django 多租户 API 中请求特定视图

Question

在 Django 2.2.17 中使用 django-tenant-schemas==1.10.0 创建了一个多租户 API，目前正在使用 Postman 对其进行测试。

我能够创建一个新组织（即租户）并将它们全部获取

问题是，在对端点 http://127.0.0.1:8000/employee/ 的 GET 和 POST 请求中，我得到了

/employee/处的AttributeError

'str' 对象没有属性'get'

这是我的员工/views.py

from django.shortcuts import render
from employee.models import Employee
from organization.models import Organization
from django.http import JsonResponse,request, HttpResponse
from django.views import View
from tenant_schemas.utils import schema_context
import json

# Create your views here.
class EmployeeView(View):

    def get(self, request, *args, **kwargs):
        try:
            organizations = Organization.objects.get(domain_url=request.META['HTTP_HOST'])
            schema_name = organizations["schema_name"]
            #schema_name = organizations.schema_name
        except Organization.DoesNotExist:
            return "no organization"

        with schema_context(schema_name):
            employees = Employee.objects.all()
            data = {"results": list(employees.values("id","name"))}
            return JsonResponse(data)


    def post(self, request, *args, **kwargs):
        try:
            organizations = Organization.objects.get(domain_url=request.META['HTTP_HOST'])
            schema_name = organizations.schema_name
        except Organization.DoesNotExist:
            return "no organization"

        with schema_context(schema_name):
            name = json.loads(request.body)['name']
            employee = Employee(name=name)
            employee.save()
            return "Employee added successfully"

这是终端的输出

Internal Server Error: /employee/
Traceback (most recent call last):

    response = get_response(request)

    response = self.process_response(request, response)

    if response.get('X-Frame-Options') is not None:
AttributeError: 'str' object has no attribute 'get'

这是 Postman 中的 Traceback

Answer 1

看起来您正在从视图中返回原始字符串。您需要返回HttpResponse 的实例（或使用render 等）

例如，您有以下内容：

def get(self, request, *args, **kwargs):
    try:
        organizations = Organization.objects.get(domain_url=request.META['HTTP_HOST'])
        schema_name = organizations["schema_name"]
        #schema_name = organizations.schema_name
    except Organization.DoesNotExist:
        return "no organization"

它到达了return "no organization" 代码分支，然后打破了 Django 的中间件期望。
