router.register(), AttributeError: module 'rest_framework.views' has no attribute

Question

I don't know what I am doing wrong. I have been battling with this error for hours. I have opened all the suggestions I saw and implemented what they suggested but still, the error is pending

router.register(r'^hmos/$', views.HMOList), AttributeError: module 'rest_framework.views' has no attribute 'HMOList'

This is "core/urls.py"

from django.conf.urls import url
from  .views import *
from django.urls import path
from rest_framework.urlpatterns import format_suffix_patterns
from rest_framework_jwt.views import obtain_jwt_token,refresh_jwt_token
from rest_framework.routers import DefaultRouter
router = DefaultRouter()

 router.register('hmos', views.HMOList)

urlpatterns = format_suffix_patterns(urlpatterns)

This is "core/views.py"

 'message': 'HMO could not be created with received data.',

    url(r'^admin/', admin.site.urls),
    url('api/core/', include('core.urls')),
]

In "core/urls.py" you should have :

from  .views import HMOList
router.register(r'hmos', HMOList)
urlpatterns = router.urls
