Django - Display success messages for 10 or 20 seconds in Django Admin Panel
I was working in Django admin. So while saving a modal there is an automatic success message that appears after saving. I was wondering if it is possible to set the time limit for the message to appear. So that after few seconds it deletes automatically!! In the picture below after creating a project and saving it there is a success message which says "The project 'xyzproject' was added successfully". But this message remains on the page until I refresh the page. so can anyone tell me if its possible to add a time limit for the message to appear and disappear without refreshing the page. -
decoding a list from a channels.http.AsgiRequest
I have a docker container which sends data_dict, a dictionary {'dome_temp": 15.5C, 'humidity":71%} using the requests library https://requests.readthedocs.io/en/latest/user/quickstart/ with the following code response = requests.post(dome_control_target, data=data_dict) It is received in another container running django via a daphne server. It is received in a channels consumer with this code: def receive_temperhum_data(request): logger.info(f"message received from temperhum {request.data}") return HttpResponse("temperhum data received") request.data returns the error 'AsgiRequest' object has no attribute 'data' So does request.message Request is type: 'channels.http.AsgiRequest' and has the plain text of <AsgiRequest: GET '/dome_control/temperhum/?dome_temp=15.5C&humidity=71%25'> I want to process this data in the consumer. I suppose I could just parse the text, but does anyone know how I can extract the data as a dictionary ? Thank you -

Django TypeError: expected string or bytes-like object
I don't know why am receiving this error in the first place check the whole code thrice I am calling out a signal from Django View to create an object in the model for analytical purpose. models.py RECEIVER_REQUEST_TYPE = ( ('ABOX', 'Android Bounding Box'), ('ENTR', 'Web Bounding Box'), ) class BaseAnalytics(models.Model): """Common filds for all the tables""" ip_address = models.CharField(max_length=220, blank=True, null=True) content_type = models.ForeignKey( "contenttypes.ContentType", on_delete=models.CASCADE, blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) # status = models.IntegerField(blank=True, null=True) execution_time = models.TimeField(verbose_name='Time Taken for each qeury to execute') class ReceiverAnalytics(BaseAnalytics): """reciever analytics""" longitude = models.FloatField(blank=True, null=True) latitude = models.FloatField(blank=True, null=True) request_type = models.CharField(max_length=4, choices = RECEIVER_REQUEST_TYPE) def __str__(self): return str(self.id) class Meta: verbose_name = 'Receiver Analytics' verbose_name_plural = 'Receiver Analytics' # SIGNAL def receiverAnalyticsSignal(sender, request, request_type, time, longitude, latitude ,*args, **kwargs): pdb.set_trace() c_type = ContentType.objects.get_for_model(sender) new_call_obj = ReceiverAnalytics.objects.create( ip_address = get_client_ip(request), content_type = c_type, request_type = request_type, longitude = longitude, latitude = latitude, execution_time = time, ) print(new_call_obj) object_viewed_signal.connect(receiverAnalyticsSignal) Signal.py from django.dispatch import Signal object_viewed_signal = Signal(providing_args=['request']) Views.py object_viewed_signal.send( Receive, request_type='NRBY', longitude=longitude, latitude=latitude, time=total_time, request=request ) Here are types of fields --------------- Receive > model_name mark NRBY > String enum longitude, latitude, time > … -
Django 2.2 - how to express a constraint between two fields
I have a couple of models that look like this: class AlarmStatus(Enum): UNDEFINED = "Undefined" PENDING = "Pending" CUSTOMER_PENDING = "Customer Pending" @classmethod def choices(cls): return tuple((i.name, i.value) for i in cls) class Alarm(models.Model): managed = models.BooleanField(default=False, blank=False, verbose_name="Managed ?") status = models.CharField( max_length=20, default=AlarmStatus.UNDEFINED.name, choices=AlarmStatus.choices() ) class Meta: constraints = [ models.CheckConstraint( check=Q(managed=False) & Q(status=AlarmStatus.UNDEFINED.name), name="if_managed_is_False_status_must_be_UNDEFINED") ] I would like to enforce at the db level the following invariant: if an alarm managed field is False, then its status field MUST be "UNDEFINED". I.e. I want to declare illegal the following state/combination: managed == False AND status == (PENDING | CUSTOMER_PENDING) How can I enforce this? I tried with the above constraint but it is clearly wrong, because it is enforcing that every row managed field must be False AND every row status must be UNDEFINED. Thanks -
How can I prerun my APIs from my Django Restful API dashboard
I currently have this Django Swagger API dashboard and I want to run the APIs that I've already ran, I want to try loading the APIs into a text file and run the text file.
