Class CompanySerializers missing“Meta.model”attribute我一直在使用Django Rest Api Framework制作API，每当我运行我的应用程序时，它都会显示上述错误。

我的Serializers.py：

from rest_framework import serializers
from api.models import Company

# Create Serializers here

class CompanySerializers(serializers.HyperlinkedModelSerializer):
    class Meta:
        model: Company
        fields = "__all__"

我的model.py：

from django.db import models

# Create your models here.
#Creating Company model
class Company(models.Model):
    company_id = models.AutoField(primary_key= True)
    name = models.CharField(max_length=50)
    location = models.CharField(max_length= 50)
    about = models.TextField()
    type = models.CharField(max_length= 100, choices=
                            (('IT','IT'), ('Non IT', 'Non_IT'), ('Mobiles_phones', 'Mobiles_phones'))) 
    added_Date = models.DateTimeField(auto_now=True)
    active = models.BooleanField(default=True)

我的views.py：

from django.shortcuts import render
from rest_framework import viewsets
from api.models import Company  
from api.serializers import CompanySerializers 
# Create your views here.
class CompanyViewSet(viewsets.ModelViewSet):
    queryset = Company.objects.all()
    serializer_class = CompanySerializers

我已经尝试了一切，但无法解决它。请大家看看这个，这将是非常有帮助的。
