请求Django multitenant API中的特定视图

Question

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

我能够创建一个新的组织（即租户）并获得所有这些组织

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

AttributeError at /employee/

'str' object has no attribute '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/

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

例如，您具有以下功能：

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"

它击中了return "no organization"代码分支，这打破了Django对中间件的期望
