Can a Django ModelForm save multiple new models on a single submit?
I am learning Django and building a website to save and display cafeteria food offerings. I have a Model Meal and another FoodItem, where multiple FoodItems are children of a Meal. class Meal(models.Model): date = models.DateField(default=datetime.date.today) BFAST = 0 LUNCH = 1 DIN = 2 MEAL_TIME_CHOICES = [ (BFAST, 'Breakfast'), (LUNCH, 'Lunch'), (DIN, 'Dinner'), ] meal_time = models.IntegerField( choices = MEAL_TIME_CHOICES, default = MEAL_TIME_CHOICES[0] ) class FoodItem(models.Model): meal = models.ForeignKey(Meal, on_delete=models.CASCADE) name = models.CharField(max_length=80) I'd like to create a ModelForm that has multiple textinputs for FoodItems so that multiple foods can be saved and associated with the same meal on a single submission of the form. My attempt right now only allows me to submit a single food item at a time. class FoodItemForm(forms.ModelForm): class Meta: model = FoodItem fields = ('name',) Any assistance in doing this the correct way would be much appreciated! -
Can not switch from assigning permission_classes to use decorator @permission_classes
The below is an api that required authen. It works class some_random_api(generics.GenericAPIView): permission_classes = (IsAuthenticated, ) def get(self,request): return HttpResponse("Called successfully") However, I dont like declaring variable. After looking up this document, https://www.django-rest-framework.org/api-guide/permissions/ . I find an alternative way by using decorator. So I change my code into this. from rest_framework.decorators import permission_classes class some_random_api(generics.GenericAPIView): @permission_classes(IsAuthenticated) def get(self,request): return HttpResponse("You call random test api") Now this API does not check Authen -
should Stripe be integrated in frontend or backend ? (React+Django Rest )
just a bit confused as i found both solutions after a day of research. some suggest to use "pip install dj-stripe" and add keys and other options in "settings.py". Then the script in frontend to get redirect button and some suggest the use of "npm install --save @stripe/react-stripe-js @stripe/stripe-js", and add keys in "app.js" or a designated js file. i would like to know if it differs (security ,efficiency,.. wise), or is there a concrete way of doing it (best practice way), thank you. -
How to get a value from one method to another within a model observer
Here is an example from the filtering model observer: class MyConsumer(GenericAsyncAPIConsumer): ... @action() async def subscribe_to_comment_activity(self, user_pk, **kwargs): # We will check if the user is authenticated for subscribing. user = await database_sync_to_async(User.objects.get)(pk=user_pk) await self.comment_activity.subscribe(user=user) I want to do some filtering, but that is only possible for my case if I have the instance at hand to filter against. That means as I see it, I need the user=user value in the observer serializer method. @comment_activity.serializer def comment_activity(self, instance: Comment, action, **kwargs) -> CommentSerializer: '''This will return the comment serializer''' return CommentSerializer(instance) And here comes my question then, how can I get the user value in the model serializer method? -
django channels: updates to the data base deletes older data from the same session on the socket
So I'm building a tic tac toe game which you can play online, but I wanted to save the win / lose count of each user and I'm using django 3.2 ,channels 3 and channels_presence with python 3.9 I've built the socket and the client successfully and now you can play as much games as you would like... I think The problem is that the score I try to save get stored in the data base but after another game the score returns back to zero so if two users are playing in a room and user 1 won 2 games the score would get updated then if the other user won a game his score would be 1 and the user 1 score would be reset to zero My User model class CustomUser(AbstractUser): won_games = models.IntegerField(default=0) lost_games = models.IntegerField(default=0) draw_games = models.IntegerField(default=0) def win(self): self.won_games += 1 self.save() def lose(self): self.lost_games += 1 self.save() def draw(self): self.draw_games += 1 self.save() I've put this into the receive function in my consumers.py if text_data['type'] == 'completed': self_channel = Presence.objects.get(channel_name=self.channel_name) competitor = self_channel.room.presence_set.filter(~Q(channel_name=self_channel)).first().user competitor = CustomUser.objects.get(email=competitor.email) user = self.scope['user'] print(user.email, competitor.email) if competitor: competitor.win() if user.is_authenticated: user.lose() return **Note: **I'm relying on … -

Inner joins with timestamps in Django ORM
Django documentation states to check the ORM before writing raw SQL, but I am not aware of a resource that explains how to perform inner joins between tables without foreign keys. Many of the tables in my database need to be joined by time-related properties or intervals, which to my knowledge do not serve well as foreign keys. For example, in this basic example I need to first take a subset of change_events, and then join a different table ais_data on two separate columns: models.py class AisData(models.Model): navstatus = models.BigIntegerField(blank=True, null=True) start_ts = models.DateTimeField() end_ts = models.DateTimeField(blank=True, null=True) destination = models.TextField(blank=True, null=True) draught = models.FloatField(blank=True, null=True) geom = models.PointField(srid=4326) imo = models.BigIntegerField(primary_key=True) class Meta: managed = False db_table = 'ais_data' unique_together = (('imo', 'start_ts'),) class ChangeEvent(models.Model): event_id = models.BigIntegerField(blank=True, null=True) imo = models.BigIntegerField(blank=True, null=True) timestamp = models.DateTimeField(blank=True, null=True) class Meta: managed = False db_table = 'change_event' First I take a subset of change_events which returns a QuerySet object. Using the result of this query, I need to get all of the records in ais_data that match on imo and timestamp - so the raw SQL would look like this: SELECT ce.*, ad.geom FROM change_events ce JOIN ais_data ad WHERE ce.imo … -

ConnectionResetError while using fetch API to pass data to Django view which posts data to external api

So basically, what my current plan is: I have a repository in GitLab of my Django Application. I will clone it via script at some location via ssh. Inside that repository I will perform python3 manage.py makemigrations python3 manage.py migrate docker build . -t $1 docker run -d -p 8000:8000 $1 Where $1 will be the parameter I will pass to name my docker image.
