Retrieve data from django-rest to show in a form
I have two classes linked with a ForeignKey. My first class is "Categories", with "ID" and "Name" properties. The second class is "Documents", with "ID", "Title" and "User" properties, the last one is linked with a category defined in the first class. I'm developing the front-end based on Vue, so I want to know how to retrieve data from django-rest to show it in a form. For example, when a user adds a new doc, he must choose between all category options. Note that categories will be common to all documents. Example: Categories = [{"ID": 0, "Name "Sports"}, {"ID": 1, "Name": "Music"}] Form to add a new document: Title: XXXX Category: Sports, Music models.py from django.db import models class Category(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=200) class Documents(models.Model): id = models.AutoField(primary_key=True) title= models.CharField(max_length=200) category = models.ForeignKey(Category, on_delete=models.CASCADE) -

Does load balancing make sense on a single hardware server?
This might be a case of not actually understanding how load balancing works, but bear with me... I'm currently in the process of designing a web app, and have a single hardware server available to me. Most of the architectures I've come across use Nginx as a load balancer in front of multiple servers (with Nginx proxying to the different ports). My question is this: I'd quite like to use Docker to containerise Nginx and a few instances of the Django application I'm going to be running (as well as the database), but is it worth having multiple instances of an application running on a single hardware server? The server can run a few instances of the Django app on different ports, but surely load balancing is about distributing the stress across hardware, in which case there would be no point? I think a part of the confusion is the fact that 'server' can mean either hardware or software. It would be really great if someone with a better understanding could clear this up for me! Many thanks -
Advice on site development (combine static HTML files already coded with Django project)
I would like some advice on what to do on this project and clarify some ideas. I am unclear how the set of static HTML web-pages I developed (previously to starting development on Django) can be combined with the Django project. I assume templates are relevant, is it possible to pass coded HTML into template?. or can a urls be mapped simply to static HTML pages(?stored within the Django project). For the site I'm developing, At the start I coded some pages in plain HTML,CSS and Javascript. These are static, I have not used a content management system. These are stored in Folder-A in subfolders : Content,Styles,Scripts,Images. - Then for backend I chose Django, and now added another folder called Webapp to folder-A. Reading through DJango tutorials I've made a project for website within webapp, intending to have a separate app for a comments section, an app for a feedback form, and an app for a contact-to-email form. Have done the initial configuration and Installed MySql. It seems the database is hooked up to the Djgano project now. I can access first view I made + admin site after using runserver command. From what I have understood so far, the … -

How does `parent` field in this model change when we comment and reply, please explain it?
I am reading some codes and I have difficult time understanding Comment.objects.filter(parent=self), codes below: class Comment(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) timestamp = models.DateTimeField(auto_now_add=True) content = models.TextField() parent = models.ForeignKey('self', null=True, blank=True) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') def __str__(self): return f'[{self.user}] commented on [{self.object_id}]' @property def children(self): return Comment.objects.filter(parent=self) This is a comment, reply app. This is my understanding about this, please correct me if I am wrong. children property are replies of comments in Django app. Practically, if I actually comment on a post like this is a nice post, the parent field in this model will be equal to this instance of comment, namely this is a nice post, and if someone reply to this comment as thank you for comment, then again that parent would be changed with this instance of comment. I am pretty confused. Can you elaborate it further please thank you ? -
How to use reverse url within app to point to a template of a different app?
I have two apps: simulation_api and building_data. Each one has templates and urls. The urls I import in my main configuration. In my template of simulation_api I would like to set a link to my detail view of building data. This is what I am trying (in my template of simulation_api) which throws me an error (django.urls.exceptions.NoReverseMatch): {% for item in simulations.project.buildinggroup_set.all %} <a href="{% url "detail_building_group" item.id %}">{{ item.description }}</a> {% endfor%} The for loop works, the problem is the url that I am trying to reverse. I am reversing it like this in my models of building_data: class BuildingGroup(models.Model): name = models.CharField(max_length=500, null=True, blank=True) project = models.ForeignKey(Project, on_delete=models.CASCADE) def get_absolute_url(self): return reverse("detail_building_group", kwargs={"id" : self.id}) I think the problem is somehow that I reverse the url in one app but it is not recognised in the template of the other app. But maybe it's also something else... Anyone has an idea? Thanks so much in advance! Very much appreciated! Not sure if it is useful, but here my simplified model for the simulation: class Simulation(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE) my urls of building_data app_name = 'buildings' urlpatterns = [ path('list/building-group/<int:id>/', DetailBuildingGroupView.as_view(), name="detail_building_group"), ] -
Combination of swup, scrollmagic and fancybox result in a non-functional fancybox gallery, has anyone experienced that please?
this is my first question on stackoverflow, hopefully somebody can help. I'm building a django powered website and can't seem to get my fancybox gallery to work properly when swup is enabled(handles page transitions), or at least I suspect that that's related. My setup: django with photologue images parallax headers handeled by scrollmagic page transitions handeled by swup Problem: clicking a thumbnail opens the image fullscreen with no fancybox controlls, however, for a fraction of a second before the image is displayed and while its being loaded, the fancybox controls/arrows/x are there. But the result after click is a fullscreen image without navigation, the url also now points to that image with /.jpg which i think is the url generated by photologue. Most strange now: cligking a thumbnail, clicking the back button, then clicking the thumbnail again and again clicking the back button results in the image opened in a fancybox overlay as expected! :( What I've tried: - If i move the jQuery declaration in base.html to the end, fancybox works but my parallax and nabar links stop working. - if I disable swup or scrollmagic, fancybox works fine - different versions of fancybox seem to have the same … -

However, serializer.is_valid(raise_exception=True) raises the above error. serializers.py # Serializer for report class ReportAPISerializer(serializers.ModelSerializer): latitude = serializers.FloatField() longitude = serializers.FloatField() class Meta: model = Property fields = ('longitude', 'latitude', 'consumer_type', 'area', 'avg_monthly_bill',) # Serializer to get user details class UserSerializer(serializers.ModelSerializer): property = ReportAPISerializer() class Meta: model = InterestedUser fields = ('full_name', 'phone_no', 'email', 'property') def create(self, validated_data): property_data = validated_data.pop('property') user = InterestedUser.objects.create(**validated_data) Property.objects.create( owner=user, location=Point(property_data['latitude'], property_data['longitude']), area=property_data['area'], consumer_type=property_data['consumer_type'], avg_monthly_bill=property_data['avg_monthly_bill'] ) return user views.py class RegisterAPIVIew(CreateAPIView): serializer_class = UserSerializer models.py class InterestedUser(AbstractBaseUser, PermissionsMixin): user_id = models.UUIDField(default=uuid.uuid4, editable=False, primary_key=True) date = models.DateTimeField(auto_now_add=True, null=True, blank=True) full_name = models.CharField(max_length=50, default="") email = models.EmailField(blank=False, unique=True) phone_no = models.CharField(max_length=10, default="") active = models.BooleanField(default=False) staff = models.BooleanField(default=False) admin = models.BooleanField(default=False) password = models.CharField(default="", max_length=128) is_superuser = None objects = InterestedUserManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] class Meta: verbose_name = 'user' verbose_name_plural = 'users' def __str__(self): return "%s -- %s" … -
How can I capture errors and exceptions data from frontend response to django to add more context
I want to receive some parameters with my error capture on django when something wrong on the front-end I have react frontend running on a django backend. Sentry is been used to capture errors and report. In settings.py: SENTRY_DSN = os.environ.get("SENTRY_DSN") if SENTRY_DSN: sentry_sdk.init( dsn=SENTRY_DSN, integrations=[DjangoIntegration()], environment=ENVIRONMENT, release=os.environ.get("HEROKU_RELEASE_VERSION") or "HEROKU_RELEASE_VERSION not set", ) with configure_scope() as scope: scope.user = {"user": "broken lol"} This is reporting the errors from entire app. However, I want to add user ids to error Sentry reports. To do that I need to capture the response from frontend and somehow get that into settings.py and replace the "broken lol" string with UserId -
Serializer for json array
I want to get into my DRF view a json array array_example and then split it. Below is my json: { "key1": "example_key", "array_example": [ "string1", "string2" ] } This is my serializer: class ExampleSerializer(serializers.Serializer): key1 = serializers.CharField(allow_null=True, required=False) array_example = serializers.ListField(child=serializers.CharField()) And this is my view: serializer = sers.ExampleSerializer(data=request.data) serializer.is_valid(raise_exception=True) strings = ','.join(serializer.validated_data['array_example'], []) 1) Is this a correct approach for my case? 2) I get a validation error on array_example. Why ? -
Django fails on "unexpected keyword argument 'allow_blank'", even though I'm following documentation
When I tried adding the possibility for empty fields for one of my models, I get the following error-message: "TypeError: init() got an unexpected keyword argument 'allow_blank'" What I tried doing was adding the keyword "allow_blank=True" to both a TextField and a CharField. Same error in both instances. from django.db import models from django.contrib.auth.models import User class Set(models.Model): pass class Chat(models.Model): setID = models.ForeignKey(Set, on_delete=models.CASCADE) chatID = models.CharField(max_length=100) class Message(models.Model): chat = models.ForeignKey(Chat, on_delete=models.CASCADE) chatID = models.CharField(max_length=100) messageID = models.CharField(max_length=100) createdDate = models.DateTimeField() createdBy = models.CharField(max_length=1000) author = models.CharField(max_length=1000) messageDate = models.DateTimeField() text = models.TextField() class Category(models.Model): name = models.CharField(max_length=100) class Tag(models.Model): user = models.ForeignKey(User, related_name="tags", on_delete=models.CASCADE, null=True) category = models.ForeignKey(Category, on_delete=models.DO_NOTHING) value = models.TextField(max_length=None, allow_blank=True) message = models.ForeignKey(Message, on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True) flagged = models.BooleanField(default=False) What I want to do is allow an empty field in my Tag-model, so if there is a better way to do this, please do tell. -
REST Framework: Update field in one model and track changes in another model
I have two models: class CustomUser(models.Model): ... act = models.CharField(max_length=10) class ActHistory(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) last_act = models.CharField(max_length=10) act_time = models.DateTimeField(auto_now_add=True) I would like to create a single API endpoint /update/ with DRF that does this: If value vs existing act value in the model is the same, do nothing. If the values are different, update the CustomUser for the authenticated user with the value Then insert a record row in ActHistory with user=authenticated user, last_act = All the docs I managed to find only support doing either the update or create actions with each API point. Thanks in advance! -
How do I permanently publish a project prepared using Django and React?
In my project I used django in the backend and react in the frontend on the linux server. How can I make the development server from django and react running permanent? So that it does't stop when I quit the shell.
