How to receive data from user Django Rest Framework
I want to receive data from users and pass the processed version. For example user passed JSON: {"first number": 3, "second number": 4}, and the web API should response addition of numbers like {"result": 7}. How to do it without writing to the database? My serializer.py looks like: class AdditionSerializer(serializers.Serializer): first = serializers.CharField() second = serializers.CharField() views.py: class AdditionView(APIView): @action(detail=False) def get_addition(self, request): try: serializer = AdditionSerializer(data=request.data) if serializer.is_valid(): first = serializer.validated_data(['first']) second = serializer.validated_data(['second']) response = {'result': first+second} return Response(response, status=status.HTTP_200_OK) else: return Response({"message":"error"}) except: None""" but it's doesn't work -
How to serialize a Join query set from several tables in Django Rest Framework
Sometimes, frameworks make things more complicated instead of simplify them. I would like to serialize a join like this one queryset = Cities.objects.raw("SELECT 1 as id, cities.name as ci, states.name as s, countries.name as co FROM cities JOIN states ON states.id = cities.state_id LEFT OUTER JOIN countries ON countries.id = states.country_id WHERE cities.name = %s", [city]) or like this one, if raw queries are not recommended city = self.request.query_params.get("cityname") As you can see this is a reverse join. The idea is to serialize a result set like this one 0: name: "Guadalajara" state: "Castilla La Mancha" country: "Spain" 1: name: "Guadalajara" state: "Jalisco" coutry: "Mexico" Two cities having the same name, but belonging to different states and countries. I need this to implement a sort of autocomplete feature. This is actually a pseudocode but it gives an idea about the kind of JSON result I would like to get. I read the documentation and I searched the internet, I found nothing clear about how to do this. I'm new to Django and I'm completely lost, this is a simple task that would be easy to do manually, but I have no idea about how to achieve this using Django Rest … -

Form field for a foreign key in ModelForm with too many choices for ModelChoiceField?
I have a simple foreign key relationship I want to use in a ModelForm, but without a ModelChoiceField. class Sample(models.Model): alt = IntegerField(db_index=True, unique=True) class Assignment(models.Model): sample = models.ForeignKey(Sample, on_delete=models.CASCADE) I want to have the AssignmentForm select the sample based on the contents of the sample's alt field. With a ModelChoiceField it would be like this: class SampleSelect(ModelChoiceField): def label_from_instance(self, obj): return obj.alt class AssignmentForm(ModelForm): sample = SampleSelect(queryset=Sample.objects.all()) class Meta: model = Assignment fields = ['sample'] The ModelChoiceField documentation says to use something else if the number of choices is large. Allows the selection of a single model object, suitable for representing a foreign key. Note that the default widget for ModelChoiceField becomes impractical when the number of entries increases. You should avoid using it for more than 100 items. I think I need a custom form field, but I cannot figure out how to do this. class SampleBAltField(IntegerField): def clean(self, value): try: return Sample.objects.get(alt=value) except Sample.DoesNotExist: raise ValidationError(f'Sample with alt {value} does not exist') This existing code should take an integer from the form and map it back to a foreign key, but I cannot figure out what to override to populate the field for a bound form from … -
Wagtail initDateChooser is defined for one app but not the other app?
I'm creating a portfolio site and I've deployed my code to an Ubuntu server on DigitalOcean. I have two apps within my project: a blog app and a portfolio app. For the page models I created in the blog app, the DateField works fine and the little calendar picker shows up when the page is created. For the portfolio app, however, the calendar picker doesn't activate. The error in the console reads: Uncaught ReferenceError: initDateChooser is not defined <anonymous> http://MYIPADDRESS/admin/pages/14/edit/:759 I checked the Network tab to see if all the stylesheets were loading. I don't see any 400 or 500 errors. Just 200 and 304. I've tried changing the field models to DateTimeField and the same problem occurs. Deleting and re-adding the models and re-migrating also does not fix the issue. So I'm not sure what else to check at this point. Could something have gone wrong during collectstatic? Should I run that again to see if that makes a differences? Any tips you can offer would be very much appreciated. -
How to add new line inside a <p> tag in html when using Django to pass data?
I have model of Players in Django which looks like this: class Player(models.Model): name = models.CharField(max_length=200, null=False, blank=False, default='') description = models.TextField(max_length=1000, null=True, blank=True) I pass the Player objects in the context: class playerView(request): players = Player.objects.all() context = {'players':players} return render(request, 'base/players.html', context) Now, I render the description in p tag of html using below code: players.html {% for player in players %} <p>{{player.name}}</p> <p>{{player.description}}</p> {% endfor %} But when I try to add description with newlines in it like: This is line one. This is line two. It renders data like this: This is line one.This is line two. I tried adding &#13 &#10 which I found in one of the answers is a new line character, but it doesn't work. I also tried adding \n and also tried adding br tag, but that also didn't work. Please help me with a solution. -

Django form ignore validations on save vs submit
I am trying to create a Django form in which the user will have two options Save the form (temporarily) Submit the form What I am trying to do is to allow the users to save the form temporarily and after they have all the data they can come back, edit the form and make the final submission. The problem is that the form validation will not allow partially filled form to be saved. Is there any way I can ignore validations when "Save" is pressed whereas perform all the validations when "Submit" is pressed? I do not want to have 2 views. I want the same view with two buttons "Save" and "Submit" if Save is pressed some of the validations will be ignored (i.e. required field left empty due to the fact that the user might not currently have the information). But if the "Submit" is pressed, all the date should be validated. Please note that all the validations takes place backend with Django. Thanks -

Using subqueries with UPDATE in Django's ORM
Say I have two models, which I'll call ModelA and ModelB. Both models have a few fields in common, (represented by field_one, field_two, and field_three). Additionally, ModelB has a foreign key to ModelA. class ModelA(Model): field_one = models.IntegerField() field_two = models.TextField() field_three = models.BooleanField() class ModelB(Model): field_one = models.IntegerField() field_two = models.TextField() field_three = models.BooleanField() model_a = models.ForeignKey(ModelA, on_delete=models.CASCADE) I need to update all instances of ModelB to update the field's values to the values of the associated ModelA instances. I need to do this operation entirely in the database, without needing to instantiate any model instances (NOT using .save() or bulk_update()). I know how I can accomplish this in PostgreSQL using subqueries: UPDATE model_b SET (field_one, field_two, field_three) = (SELECT field_one, field_two, field_three FROM model_a WHERE model_b.model_a_id = model_a.id); How can I express the above query in Django's ORM? This is the closest I have been able to get: ModelB.objects.update( field_one=Subquery(ModelA.objects.filter(id=OuterRef('model_a_id')).values(field_one)[:1]), field_two=Subquery(ModelA.objects.filter(id=OuterRef('model_a_id')).values(field_two)[:1]), field_three=Subquery(ModelA.objects.filter(id=OuterRef('model_a_id')).values(field_three)[:1]) }) However, this results in a subquery for every single field: UPDATE model_b SET field_one = (SELECT model_a.field_one FROM model_a WHERE model_a.id = model_b.model_a_id LIMIT 1), field_two = (SELECT model_a.field_two FROM model_a WHERE model_a.id = model_b.model_a_id LIMIT 1), field_three = (SELECT model_a.field_three FROM model_a WHERE model_a.id … -
Correct way to replace Django Model class with an equivalent+decorated subclass
I'm writing a decorator intended to add functionality to decorated Django Model classes. Something like this: class NewFunctionality: @classmethod def fun1(cls): ... @property def prop1(self): ... def add_functionality(Decorated): class NewClass(Decorated, NewFunctionality): class Meta(getattr(Decorated, 'Meta', object)): app_label = Decorated._meta.app_label NewClass.__name__ = Decorated.__name__ NewClass.__doc__ = Decorated.__doc__ return NewClass @add_functionality class MyModel(models.Model): ... This seems to work until there are two decorated model classes, when I get an error Conflicting 'modelclass' models in application 'my_app'. This is apparently due to the registry of models that Django keeps, which clearly has some automagic that doesn't appreciate new model classes being made, even if they are direct replacements of the existing one. Is there anything I can do to accomplish this, other than by monkeypatching the decorated class, adding each needed method? -
How to find relationship between two objects Django in large codebase
I'm working on a new large codebase. There are a ton of models with foreign key relationships and I'm having a hard time keeping them all in my head as I click through the different foreign key relationships. I'm using PyCharm so it's nice to be able to click through the different relationships. The problem is if I have two objects that I'm are connected, i'm basically reduced to clicking down seemly endless relationship paths, which is time consuming and confusing. A lot of times I'll find my self many levels deep from the object I started at and run into a dead end, then I'll have to chase back up the tree and try another path. I tried to use this tool in an attempt to auto draw a uml, but the uml has so many lines between the different objects, I can't tell which ones are connected and it also outputs a png, so I can't search for a model. Does anyone have a recommendation on how I can do this more easily? -
