How to properly set up Viber bot in Python (Django)
I'm an absolute beginner in Viber bot, and I can't make my bot send a Welcome (or any other) message to the user, even if he has subscribed to my Viber bot account. I have tried all of the tutorials that I have found on the internet, read Viber Bot Python and REST documentation, some tutorials that I've found on github like this and this and every code possibility that has come to my mind - but I still couldn't make it to work. I have a website domain with SSL (Let's Encrypt) and everything should be fine. Also, I have used Postman to set a Webhook and received status 0 (ok), so users now can connect to my bot and message him. Here is what I've got so far views.py (django) from viberbot import Api from viberbot.api.bot_configuration import BotConfiguration from viberbot.api.messages.text_message import TextMessage from viberbot.api.messages.data_types.contact import Contact from viberbot.api.viber_requests import ViberConversationStartedRequest from viberbot.api.viber_requests import ViberFailedRequest from viberbot.api.viber_requests import ViberMessageRequest from viberbot.api.viber_requests import ViberSubscribedRequest from viberbot.api.viber_requests import ViberUnsubscribedRequest from django.views.decorators.csrf import csrf_exempt logger = logging.getLogger() logger.setLevel(logging.DEBUG) handler = logging.StreamHandler() formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s') handler.setFormatter(formatter) logger.addHandler(handler) viber = Api(BotConfiguration( name='MyBotName', avatar='https://someavatar.com/avatar.jpg', auth_token='mytoken' )) def hook(request): logger.debug("received … -

Is the any possibility of having a Profile model and Customer model in Django e-commerce development?
I wish to know the possibility of having those two models altogether with other models like Order, OrderItem etc. I tried running it like in my models.py class Profile(models.Model): user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE) name = models.CharField(max_length=30, null=True, blank=True, help_text="Insert your name") image = models.ImageField(default='default.png', upload_to='profile_pics') class Customer(models.Model): name = models.OneToOneField(Profile, on_delete=models.CASCADE) phone = models.CharField(max_length=11, null=True, blank=True) address = models.CharField(max_length=20, null=True, blank=True) phone = models.CharField(max_length=11, null=True, blank=True) address = models.CharField(max_length=20, null=True, blank=True) class Order(models.Model): customer = models.ForeignKey(Customer, on_delete=models.CASCADE, null=True, blank=True) complete = models.BooleanField(default=False, null=True, blank=True) date_ordered = models.DateTimeField(auto_now_add=True) transaction_id = models.CharField(max_length=100, null=True) Is it possible having such models like the above? If Yes, How can I present it in the views.py to authenticate a User(Profile) and at the same create a Customer. -

Related models have to be registered for the autocomplete to work, but I'd like them not to be shown in the left sidebar. Is there a way to hide them while still being able to edit them through the main model if needed? -

Where is the logging in my Django application started by uwsgi?
I use supervisor and uwsgi to start my Django. Here is the conf in supervisor. [program:myapp] directory=/home/users command=uwsgi --ini uwsgi.ini stdout_logfile_maxbytes=50MB stdout_logfile_backups=30 stderr_logfile=/var/log/supervisor/supervisor.log stdout_logfile=/var/log/supervisor/supervisor.log And this is the ini file of uwsgi [uwsgi] http-socket=0.0.0.0:8080 wsgi-file=myapp/wsgi.py logformat=%(ltime) "%(method) %(uri) %(proto)" status=%(status) res-time=%(msecs)ms logto=/var/log/supervisor/uwsgi.log In this way, only method, status and time to reponse etc is listed as follow 14/Jan/2022:13:19:46 +0800 "GET /model/task/?taskid=e69a757974f811ec93e1f58ac6e34980&current=1&pageSize=10000&total=0&model_id=1 HTTP/1.1" status=200 res-time=107ms 14/Jan/2022:13:19:45 +0800 "POST /model/runmodel/ HTTP/1.1" status=200 res-time=3508ms What I want is if I add a logging.info or logging.debug in my application, it can also writes to the log file. From the doc of uwsgi, it seems I cannot accomplish that by the logformat parameter. Anyone knows if it's possible to do it? -
Add new entries to the model incrementing the latest value with three digits
I have a model, with a column named reference. Each reference has values like this: 106739D/4115110 106739D/4115111 106739D/4115112 and so on... From my view, I send a count of previous projects to the template, like this (truncated): def add_new_project(request, pk): context = {} projects = Project.objects.all().filter(project_id=pk).count() context['projects'] = projects Then in my template, I retrieve some value like 106739D/41151 + 1 (from count) = 106739D/411511 Template: <div class="col-sm"> <input type="text" name="reference" class="form-control" value="{{ some_given_value }}{{ projects }}" required> </div> It actually does the job, it increments the value one by one each time I create a new project, but I've been requested to do it with this format 00X: 106739D/4115110 --> 106739D/411511000 106739D/4115111 --> 106739D/411511001 106739D/4115112 --> 106739D/411511002 So basically I need to add 00X instead of X. Is there any efficient - pythonic way to do that?
