django rest framework: Get nested representation of child elements
I have a tree of items which reference each other as parent/children. Now I want to get them through the API as nested objects to minimize the requests. My problem is that I can't initiate the serializer class from within itself (obviously)... Is there a way to do this? Model: class Item(models.Model): name = models.CharField(max_length=128) dashboard = models.ForeignKey(Dashboard, on_delete=models.CASCADE) config = models.JSONField(null=True, blank=True) parent = models.ForeignKey("Item", on_delete=models.CASCADE, related_name="children", null=True, blank=True) previous = models.OneToOneField("Item", related_name="next", null=True, blank=True, on_delete=link_previous_item_on_delete) Serializer: class ItemSerializer(serializers.HyperlinkedModelSerializer): children = ItemSerializer(many=True, read_only=True) class Meta: model = Item fields = ("name", "dashboard", "config", "children") -
Is there a way to use a temporary non-field variable in factoryboy?
I am defining some factories for testing my e-commerce store. I have created a Faker provider that can return, for instance, a dictionary containing all the data for a random product. I want to then use that dictionary to populate the fields in my factory. This is because the data in the dictionary is coherent. I don't want to create a factory with data that is not coherent e.g. a Product with name: "Short sleeve t-shirt" and then description: "Beautiful, comfortable shoes." Is there a way that I can implement something similar to class ProductFactory(factory.django.DjangoModelFactory): temporary_product_dict = fake.product_dict_from_provider() name = temporary_product_dict["name"] description = temporary_product_dict["description"] category = temporary_product_dict["category"] ... class Meta: model = models.Product When I do this exact thing, I get an error which tells me that temporary_product_dict is not an attribute of the Product model. -
Load values from Models.py into Views.py
I am trying to create a page that allows a user to change certain CSS variables in the Django admin page and I am having some issues pulling a single value from the models.py and assigning it to a variable in my views.py. Assigning the colors inside the Django admin page works but I am unsure of how I would go about setting the linkcolor variable in views.py to the link_color variable in models.py. views.py from django.shortcuts import render from django.http import HttpResponse from .models import cssEditor # Create your views here. def index(request): linkcolor = "#000" # Grab link_color from models.py here linkfont = "Brush Script MT" # Grab link_font from models.py here linkbc = "whitesmoke" # Grab link_bc from models.py here return render(request, "SocialLinks/index.html", {"linkcolor":linkcolor, "linkfont":linkfont, "linkbc":linkbc}) models.py from django.db import models # Create your models here. class cssEditor(models.Model): link_color = models.CharField(max_length=7, default="000000") link_font = models.CharField(max_length=15, default="Brush Script MT") link_bc = = models.CharField(max_length=7, default="#F5F5F5") admin.py from django.contrib import admin from SocialLinks.forms import * # Register your models here. @admin.register(cssEditor) class cssEditor(admin.ModelAdmin): form = cssForm forms.py from django.forms import ModelForm from django.forms.widgets import TextInput from SocialLinks.models import * class cssForm(ModelForm): class Meta: model = cssEditor fields = "__all__" widgets … -
how to auto set the topic of a comment to the same topic with the post

Proper way to use clean_email in DRF
I've defined the model as pass and I'm using the UserSerializer to validate the password and create a new user. What I'm trying to do is that people can only SignUp if it's not with a known provider such gmail.com, outlook.com, live.com, etc. I know in DJango there is the clean_emailfeature that would help with something like this: class SignUpForm(forms.ModelForm): class Meta: model = SignUp fields = ['username', 'email'] def clean_email(self): email = self.cleaned_data.get('email') email_base, provider = email.split("@") domain, extension = provider.split('.')

Django response - if POST = None leave blank key, value pair from jsonresponse
the below form + view works fine forms.py class FormGlobalSettings(forms.Form): global_font_family = forms.TypedChoiceField(required=False, label='Font Family', choices=choices_font_family, empty_value=None) views.py def main_view(request): if request.method != 'POST': form_global_settings = FormGlobalSettings() else: form_global_settings = FormGlobalSettings(data=request.POST) if all([form_global_settings.is_valid()]): cleaned_data = form_global_settings.cleaned_data nested_data = {"fontFamily": cleaned_data3['global_font_family']} return JsonResponse(nested_data) return render(request, 'pbi_theme_app/index.html', {'form_global_settings': form_global_settings}) Output is: {"fontFamily": "Arial"} However, what I am trying to achieve is, that sometimes the POST request is blank/empty/null, as the user doesn't want to have any value in this field. The choices for the global_font_family are set up in this manner: choices_font_family = [(None, ""), ("Arial", "Arial"), etc..] Meaning that the if the user leaves the field empty, it results into None. This results into having it in the json as null: {"fontFamily": null} Now what I am trying to achieve, and because I have hardcoded "fontFamily" into the jsonresponse, I want the whole key, value pair to be gone if the user decides to have the field empty, meaning that the whole key, value pair "fontFamily: null is gone from the jsonresponse. To summarize: I need to somehow make the key in the json dynamic, and when the POST request is empty, I want to leave the whole key, value pair … -

Django field DateField with year only or with year and month etc. with filtering

Django - constructing multi column indexes
Say we have a model that looks thus: class Entry(models.Model): """Users will query for entries with various combinations of filters""" date_created = models.DateTimeField(auto_now_add=True) important = models.BooleanField(default=False, null=False) urgent = models.BooleanField(default=False, null=False) user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) What is the correct way to create indexes that will cater for any combination of the above fields in filters? E.g. .filter(date_created__year='2021', important=False, user=1) My first thought was the below but I have a suspicion I'm doing something wrong here... class Meta: indexes = [models.Index(fields=['-date_created']), models.Index(fields=['-date_created', 'important']), models.Index(fields=['-date_created', 'important', 'urgent']), models.Index(fields=['-date_created', 'important', 'urgent', 'user']), models.Index(fields=['-date_created', 'user']), models.Index(fields=['....etc...'])] I read through the Django documentation and noted their use of the include argument that was introduced in Django 3.2, but was unable to find useful examples of it's use. Would it work in my situation? class Meta: indexes = [models.Index(fields=['-date_created'], include=['important', 'urgent', 'user'])] Thank you -

(Django) include does not import other apps' urls
In my Django project I have 2 apps: core and books. In my core/urls.py, I use python include('books.url') to import the urls from books/urls.py, but I keep getting this error I have been having this issue now that's bugging me. I had a workaround for it, though I really want to fix this. core/urls.py from django.contrib import admin from django.urls import path from django.conf.urls import include # local urlpatterns = [ path('/', include('books.urls')), path('admin/', admin.site.urls), ] books/urls.py from django.contrib import admin from django.urls import path # local from graphene_django.views import GraphQLView from books.schema import schema urlpatterns = [ path('graphql/', GraphQLView.as_view(graphiql=True, schema=schema)), ] As suggested by SO, I have: put books.urls inside the single quotes ' ' placed the path('/', include('books.urls')) on top switch from from django.urls import include to from django.conf.urls import include The only workaround I have is place all urls into the core/urls.py, but that seems too chunky in the long run. I don't get why include works for everyone but not me! Could you help me with this issue? Thank you! -

related_name in many to many field
Below is my code. class Thing(models.Model) : title = models.CharField( max_length=200, validators=[MinLengthValidator(2, "Title must be greater than 2 characters")] ) text = models.TextField() owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='fav_thing_owner') favorites = models.ManyToManyField(settings.AUTH_USER_MODEL, through='Fav', related_name='favorite_things') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) # Shows up in the admin list def __str__(self): return self.title class Fav(models.Model) : thing = models.ForeignKey(Thing, on_delete=models.CASCADE) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='favs_users') # https://docs.djangoproject.com/en/3.0/ref/models/options/#unique-together class Meta: unique_together = ('thing', 'user') def __str__(self) : return '%s likes %s'%(self.user.username, self.thing.title[:10]) But I got confused related_name in ManytoMayFied. for example, in my code I can get user's Thing(my model name) using user.fav_thing_owner. But in ManyToManyField, I have two related_name(favorite_things, favs_users). user.favorite_things and user.favs_users get same object..? -
python single and multiple button operation
I have a concern on how to stimulate single or multiple button click operations. --code sample : .js file jQuery.ajax({ url : "/", type :"POST", data : { selected_obj : clicked_btn }) .py file object_selected = request.forms.get('selected_obj') # This (object_selected) return data like # data_returned = (0.48, 0.65, 2.32) -what i need is when the button clicked for the first time data_returned gets multiplied which it is no big deal. But when clicked for the second time either same or another button that has same output i need to (multiply the returned data) for the same or another button and sum it with the previous data(button clicked for the first time), and so on ..
