Foreign key not returning child instance using django-polymorphic
I just started using django-polymorphic and I'm having trouble returning the child instance of a parent model from a Foreign Key relationship. Here's an example: >>> poll = Poll.objects.create(asker=official, question='test question',background='background') >>> poll.asker <Official: Mayor Test Official> >>> poll.save() >>> poll = Poll.objects.get(question='test question') >>> poll.asker <Asker: Test Official> In this instance, the Official model is a child of Asker. All help is appreciated, thanks! -

Django ImportError Windows
So I created a virtualenv. I activated it (workon). Then I installed Django. py -3 -m django --version returns "No module named django." Then I try pip3 install django and it returns "Already satisfied." I created my project successfully using django-admin (meaning django IS installed?). Then I cd into the folder and run py -3 manage.py runserver and it says the following: "ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?" -
Queryset distinct() with filter() and order_by() does not work
I am using the following models and forms to build two dropdown menus. The City menu is dependent upon the Country menu. Right now my code does the filtering and ordering correctly. However, distinct() is not working. I've played around with the ordering of the queries for a while and it still doesn't work. How can I fix this? models.py from django.db import models class Country(models.Model): name = models.CharField(max_length=30) def __str__(self): return self.name class City(models.Model): country = models.ForeignKey(Country, on_delete=models.CASCADE) name = models.CharField(max_length=30) def __str__(self): return self.name class Person(models.Model): country = models.ForeignKey(Country, on_delete=models.SET_NULL, null=True) city = models.ForeignKey(City, on_delete=models.SET_NULL, null=True) def __str__(self): return self.name forms.py from django import forms from .models import Person, City class PersonForm(forms.ModelForm): class Meta: model = Person fields = ('country', 'city') def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['city'].queryset = City.objects.none() if 'country' in self.data: try: country_id = int(self.data.get('country')) self.fields['city'].queryset = City.objects.filter(country_id=\ country_id).order_by('city').distinct('city').\ exclude(city__isnull=True) except (ValueError, TypeError): pass # invalid input from the client; ignore and fallback to empty City queryset elif self.instance.pk: self.fields['city'].queryset = self.instance.country.city_set.order_by('name') -

Django Serializer lookup value from id of another model
I'm using Vue as my frontend and Django DRF as my backend. I created 2 models - Snippet and age. I'm trying to return the value from the lookup table instead of the id: POST on Snippet List by passing in {title: 'x', code: 'y', age: 21} instead of passing the age id PUT on Snippet instance by passing in {age: 21} instead of passing the age id to update the record GET on Snippet List get return results with {other_fields, age: 21}. Is it possible to modify the serializer to do these? I'm using axios to call GET/POST/PUT on the REST endpoints. Snippet data as viewed in the API **Snippet List** { "id": 1, "title": "hello", "code": "print", "age": 2 }, { "id": 2, "title": "dsd", "code": "sds", "age": 1 } **Age List** { "id": 1, "year": "21", "snippets": [ 2 ] }, { "id": 2, "year": "30", "snippets": [ 1 ] } models.py class Snippet(models.Model): created = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=100, blank=True, default='') code = models.TextField() age = models.ForeignKey('age', related_name='snippets', on_delete=models.CASCADE, null=True) class age(models.Model): year = models.CharField(max_length=100) serializers.py class SnippetSerializer(serializers.ModelSerializer): class Meta: model = Snippet fields = ('id', 'title', 'code', 'age') age = serializers.ReadOnlyField(source='age.year') class ageSerializer(serializers.ModelSerializer): snippets = … -

Django/Postgres: Returning error: duplicate key value violates unique constraint

How to map JSON keys with non-alphanumeric characters in Django Rest Framework Serializer
I have some JSON keys that contain non-alphanumeric characters e.g. "my-key=" I need to map this key to a field my_key in my Django model. The traditional way to do this is to add a custom field to the ModelSerializer where you specify the source: class MyModelSerializer(serializers.ModelSerializer): my_key= = serializers.CharField(source='my_key') class Meta: model = MyModel fields = ('my-key=',) However this obviously doesn't work because: my_key= = serializers.CharField(source='my_key') is not valid python for declaring an attribute. How do I map my JSON key to the model field? -
Reusable admin form generator always checks last field
(This is all pseudocode and is not guaranteed to run.) I am trying to make a "django admin form generator function" that outputs a django form. The current use case is to write reusable code that disallows admins from leaving a field empty, without also marking these fields as non-nullable. So suppose there exists a model Foo, in which are some nullable fields: class Foo(Model): field1 = FloatField(null=True, blank=True, default=0.0) field2 = FloatField(null=True, blank=True, default=0.0) field3 = FloatField(null=True, blank=True, default=0.0) and corresponding FooAdmin and FooForm, such that these fields cannot be made None from the admin. class FooAdmin(ModelAdmin): class FooForm(ModelForm): class Meta(object): model = Foo fields = '__all__' def _ensure_no_blanks(self, field): value = self.cleaned_data.get(field) if value is None: raise forms.ValidationError(_('This field is required.')) return value # repeat methods for every field to check def clean_field1(self): return self._ensure_no_blanks('field1') def clean_field2(self): return self._ensure_no_blanks('field2') def clean_field3(self): return self._ensure_no_blanks('field3') form = FooForm As you can see, having to write clean_field1, clean_field2, and clean_field_n are repetitive and error-prone, so I write this helper function to generate model admins (pseudocode): def form_with_fields(model_class, required_fields): class CustomForm(ModelForm): class Meta(object): model = model_class fields = '__all__' def _ensure_no_blanks(self, field): print field value = self.cleaned_data.get(field) if value is None: raise … -
Idiomatic translation of Django models to different API schemas, perhaps with Django Rest Framework
Whats the best/idiomatic way to create and pass data between different API integrations in Django or with Django Rest Framework? I'm imaging something like a translation serializer that hooks between APIs that could be reused everywhere, and wanted to see what the best practices are. Say I have a standard Django Rest Framework based API and model that I expose via DRF that looks something like this : (But has alot more complexity and nested relationships class Person(models.Model): first_name = models.CharField(max_length=255, blank=True, null=True) middle_name = models.CharField(max_length=255, blank=True, null=True) last_name = models.CharField(max_length=255, blank=True, null=True) company = models.ForeignKey(Company, blank=True, null=True) class PersonSerializer(serializers.HyperlinkedModelSerializer): company = CompanySerializer(required=False) class Meta: model = Person fields = '__all__' class PersonViewSet(viewsets.ModelViewSet): queryset = Person.objects.all() serializer_class = PersonSerializer Response looks something like this { "first_name": "Oliver", "middle_name": null, "last_name": "Zhou", "company": { "name": "Company ABC", "url": "http://localhost:8000/companies/1234/" } } Now, depending on different actions in the application, I have a different API I need to integrate with and pass the Person data to, for example, an API with a schema with something like this : { "first_name": "Oliver", "middle_name": null, "last_name": "Zhou", "company": { "name": "Company ABC" } } What I've been doing is ugly and a spaghetti network … -
How to pass a user instance in a class-based view

Express multiple one-to-many and one-to-one relationship in Django
I am designing a delivery app. It has User, Address and Store models. I have following requirements: User can have multiple delivery address Store is located at only one location. An address cannot be linked with both user and store. Models looks as follow: class User(AbstractBaseUser): ... class Address(models.Model): ... class Store(models.Model): ... First requirement can be shown as: user = models.ForeignKey(User, on_delete=models.CASCADE) Second requirement can be shown as(in Address model as): store = models.OneToOneField(Store, on_delete=models.CASCADE) Also, second requirement can be shown as(in Store model as): address = models.OneToOneField(Address, on_delete=models.CASCADE) What is the best way to represent the third requirement. And how do I take care of serialization in this case? Thanks. -
view is correct, but django templates aren't rendering
I'm trying to figure my URLs out. My views seems to function in the console, but nothing renders in the templates after the search is completed. My search seems to function regardless of what i have in the user_list function as long as the user is defined with the following: user_list = Employee.objects.all() args = {'users':users} return render(request, 'user_list.html', args) My user_list falls under search and functions correctly with the filter. return render(request, 'user_list.html', args) It's after the filter that I try to render a view called results with: return render(request, 'results.html', args) The navigation is correct and it takes me to the URL and I can view the POST from the previous view in the console and it is correct.

Any idea how to unregister customized menus? The docs only show how to add them and I don't see any unregister attribute on menu_pool. I blindly tried menu_pool.clear(), but that didn't work. The prior menus remain discoverable with menu_pool.get_registered_menus() and in logging. -
Django model's clean() method not raising the expected ValidationErrors for individual fields
I have a Django model called CheckIn with (among others) two fields, min_weeks and max_weeks. I would like to build in validation such that min_weeks is always less than or equal to max_weeks. Following https://docs.djangoproject.com/en/dev/ref/models/instances/?from=olddo#django.db.models.Model.clean (in particular, the last example in which the ValidationError is passed a dictionary which maps fields to errors), I tried the following clean() method: from django.db import models from django.core.exceptions import ValidationError class CheckIn(models.Model): min_weeks = models.IntegerField(blank=True, null=True) max_weeks = models.IntegerField(blank=True, null=True) def clean(self): if self.min_weeks > self.max_weeks: raise ValidationError({ 'min_weeks': ValidationError("'min_weeks' should be smaller than 'max_weeks'", code='invalid'), 'max_weeks': ValidationError("'max_weeks' should be greater than 'min_weeks'", code='invalid')}) The model is used in a ModelForm: class CheckInForm(forms.ModelForm): class Meta: model = CheckIn fields = [ 'min_weeks', 'max_weeks', ] The fields are displayed manually in the template. Here is an excerpt: <div class="row"> <div class="input-field col s4"> <div class="js-hide-edit-field-text {% if not check_in_type or form.min_weeks.value %}hide{% endif %}"> {% if check_in_type and not form.min_weeks.value %} <span class='js-max-weeks inherited-field text'>{{ check_in_type.min_weeks }}</span> <a href='#' class='js-hide-edit-field-edit edit-icon right'><i class="material-icons">mode_edit</i></a> <label class="active"> Min Weeks </label> {% endif %} </div> <div class="js-hide-edit-field {% if check_in_type and not form.min_weeks.value %}hide{% endif %}"> {{ form.min_weeks|add_error_class:"invalid"|attr:"data-duration-weeks-mask" }} {{ form.min_weeks.errors }} {{ form.min_weeks|label_with_classes }} </div> </div> …
