To set up structured logging in your Django website, follow these steps:

1. Add RequestMiddleware in your project's settings:

# myproject/settings/_base.py
MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
    "django.middleware.locale.LocaleMiddleware",
    "django_structlog.middlewares.RequestMiddleware",
]

2. Also in the same file, add Django logging configuration:

# myproject/settings/_base.py
LOGGING = {
    "version": 1,
    "disable_existing_loggers": False,
    "formatters": {
        "json_formatter": {
            "()": structlog.stdlib.ProcessorFormatter,
            "processor": structlog.processors.JSONRenderer(),
        },
        "plain_console": {
            "()": structlog.stdlib.ProcessorFormatter,
            "processor": structlog.dev.ConsoleRenderer(),
        },
        "key_value": {
            "()": structlog.stdlib.ProcessorFormatter,
            "processor":  
             structlog.processors.KeyValueRenderer(key_order=
             ['timestamp', 'level', 'event', 'logger']),
        },
    },
    "handlers": {
        "console": {
            "class": "logging.StreamHandler",
            "formatter": "plain_console",
        },
        "json_file": {
            "class": "logging.handlers.WatchedFileHandler",
            "filename": os.path.join(BASE_DIR, "tmp", "json.log"),
            "formatter": "json_formatter",
        },
        "flat_line_file": {
            "class": "logging.handlers.WatchedFileHandler",
            "filename": os.path.join(BASE_DIR, "tmp", 
           "flat_line.log"),
            "formatter": "key_value",
        },
    },
    "loggers": {
        "django_structlog": {
            "handlers": ["console", "flat_line_file", "json_file"],
            "level": "INFO",
        },
    }
}

3. Also, set structlog configuration there:

# myproject/settings/_base.py
structlog.configure(
    processors=[
        structlog.stdlib.filter_by_level,
        structlog.processors.TimeStamper(fmt="iso"),
        structlog.stdlib.add_logger_name,
        structlog.stdlib.add_log_level,
        structlog.stdlib.PositionalArgumentsFormatter(),
        structlog.processors.StackInfoRenderer(),
        structlog.processors.format_exc_info,
        structlog.processors.UnicodeDecoder(),
        structlog.processors.ExceptionPrettyPrinter(),
        structlog.stdlib.ProcessorFormatter.wrap_for_formatter,
    ],
    context_class=structlog.threadlocal.wrap_dict(dict),
    logger_factory=structlog.stdlib.LoggerFactory(),
    wrapper_class=structlog.stdlib.BoundLogger,
    cache_logger_on_first_use=True,
) 

4. In views.py of the likes app, let's log the object that will be liked or unliked:

# myproject/apps/likes/views.py
import structlog

from django.contrib.contenttypes.models import ContentType
from django.http import JsonResponse
from django.views.decorators.cache import never_cache
from django.views.decorators.csrf import csrf_exempt

from .models import Like
from .templatetags.likes_tags import liked_count

logger = structlog.get_logger("django_structlog")


@never_cache
@csrf_exempt
def json_set_like(request, content_type_id, object_id):
    """
    Sets the object as a favorite for the current user
    """
    result = {
        "success": False,
    }
    if request.user.is_authenticated and request.method == "POST":
        content_type = ContentType.objects.get(id=content_type_id)
        obj = content_type.get_object_for_this_type(pk=object_id)

        like, is_created = Like.objects.get_or_create(
            content_type=ContentType.objects.get_for_model(obj),
            object_id=obj.pk,
            user=request.user)
        if is_created:
            logger.info("like_created",  
            content_type_id=content_type.pk, 
            object_id=obj.pk)
        else:
            like.delete()
            logger.info("like_deleted",  
            content_type_id=content_type.pk, 
            object_id=obj.pk)     

        result = {
            "success": True,
            "action": "add" if is_created else "remove",
            "count": liked_count(obj),
        }

    return JsonResponse(result)
