Django Hotels API

This is a Django REST API for managing and retrieving hotels, room types, availability, and bookings.

This service is a sibling of django-trips, and is a core component of the DestinationPak project — a platform designed to make exploring and booking adventures across Pakistan easier and more accessible.

Installation

Simply do:

pip install django-hotels

Usage

Add the app (and django_filters, used by the catalog/availability filtering below) into your installed apps in your project's settings file.

INSTALLED_APPS = [
    ...
    'django_filters',
    'django_hotels',
]

Migrate

python manage.py migrate

Add the following to your root urls.py or to your desired file location.

urlpatterns = [
    ...
    path('hotels/', include('django_hotels.urls')),
]

This mounts the whole app under your own chosen namespace (hotels/ above - replace with whatever prefix you like) with the lib's own v1/ version underneath it, e.g. hotels/v1/hotels/. The app versions itself independently of your project's own API version.

Domain model

HotelOwner (the business/brand)
  └── Hotel (one bookable property)
        ├── HotelImage
        └── HotelRoomType (a room category/tier)
              └── HotelAvailability (a dated, priced, bookable instance)
                    └── HotelBooking (a guest or logged-in traveller's booking)

HotelOwner/Hotel deliberately carry no login/auth/permission fields — this package is tenancy-oblivious, the same way django-trips is. A consuming project owns the membership layer (who may manage which HotelOwner), not this library.

Public API

Read-only and unauthenticated (AllowAny) unless noted:

• hotels/ - the published catalog. Filterable via query params: ?city=, ?status=, ?owner=<id>.
• hotels/<slug>/ - one hotel's detail, including its room types.
• owners/ - active, verified HotelOwners.
• availabilities/ - date-range availability search across active hotels' room types. Filterable via ?hotel=<slug>, ?room_type=<id>, ?date_from=, ?date_to= (any combination; omitting all three returns every upcoming bookable date).
• bookings/create/ - guest booking (no auth required).
• bookings/lookup/?number=&email= (or &otp= instead of email) - guest "find my booking".
• bookings/<number>/ - authenticated traveller's own booking (retrieve/update).
• schema/, schema/swagger-ui/, schema/redoc/ - this app's own OpenAPI schema, scoped to just these endpoints regardless of what else your project mounts.

Custom Location model

django_hotels.Location (a plain name/slug/lat/lng model, no region/parent hierarchy) is swappable, the same way Django's own AUTH_USER_MODEL is - if your project already has its own location/city model, you don't have to duplicate location data into a second table just to install this app.

Two settings, both optional and both defaulting to this package's own bundled model:

• DJANGO_HOTELS_LOCATION_MODEL - an "app_label.ModelName" string naming which model actually satisfies Hotel.location, e.g. DJANGO_HOTELS_LOCATION_MODEL = "myapp.City". Your model doesn't need to share Location's field names.
• DJANGO_HOTELS_LOCATION_ADAPTER - a dotted path to a django_hotels.location_adapter .LocationAdapter subclass telling this app how to read your model's fields as if they were Location's (get_name, get_slug, get_lat, get_lng). Every place this app reads a location goes through django_hotels.location_adapter.get_location_adapter(), never by field name directly, so your adapter is the only place that needs to know your model's real shape.

Set both before your project's first migrate. Like AUTH_USER_MODEL, this is a swappable-model setting - Django resolves it once when the app loads, and a swap made after Location's own table has already been created doesn't retroactively move existing data.

Hotel.city (the original free-text field) stays in place alongside the new Hotel.location FK for now - a data migration best-effort backfills location from each existing city string (matching or creating a Location by name), leaving it null wherever city is blank. city itself is only dropped once every consumer has finished backfilling against its own chosen Location model.

For a worked example of a real swap: the DestinationPakistan platform (this package's own primary consumer, a private project) points this setting at its own public.City model via a HotelsRentalsCityLocationAdapter in its djangoapps/public/adapters.py - the same shape sketched above, just concretely filled in.

Local development

All commands assume Docker (make dev.up, make update_db, make test) — see the Makefile for the full command list (make help).
