urls.py

from .views import CrudAPIView

urlpatterns = [
    path('', CrudAPIView.as_view())
]

views.py

from .multi_action_view import BaseConnector
from .actions import CheckDateView

class CrudAPIView(BaseConnector):
    actions = {
        'date': CheckDateView
    }

Multiple actions on one single endpoint.

Steps

• Create a view inheriting BaseConnector as shown in views.py
• Create actions inheriting BaseAction as shown in actions.py
• Add actions to your view(check line 4-6 in views.py

Pass 'action_id' and 'target' and other parameters you want.

Note: This uses Django rest framework
