Django rest Framework : Behavior of a PrimaryKeyRelatedField with a nested representation
I have an API built with django rest framework. Here is the code : models.py class Ingredient(models.Model): barcode = models.CharField(max_length=13, primary_key=True) name = models.CharField(max_length=255) image = models.CharField(max_length=255) class Recipe(models.Model): name = models.CharField(max_length=255) favorite = models.BooleanField() owner = models.ForeignKey( 'auth.User', related_name="recipes", on_delete=models.CASCADE) class Component(models.Model): ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE) recipe = models.ForeignKey( Recipe, related_name='components', on_delete=models.CASCADE) quantity = models.FloatField() serializers.py class IngredientSerializer(serializers.ModelSerializer): name = serializers.CharField(read_only=True) image = serializers.CharField(read_only=True) class Meta: model = Ingredient fields = '__all__' class ComponentSerializer(serializers.ModelSerializer): ingredient = serializers.PrimaryKeyRelatedField(queryset=Ingredient.objects.all()) # ingredient = IngredientSerializer() class Meta: model = Component fields='__all__' class RecipeSerializer(serializers.ModelSerializer): components = ComponentSerializer(many=True) owner = serializers.ReadOnlyField(source='owner.username') class Meta: model = Recipe fields = '__all__' With the code in this state, I can create a new component by selecting a existing ingredient, an existing recipe and entering a quantity. However, the serialization of the components is not nested : { "id": 8, "quantity": 123.0, "ingredient": "3218930313023" }, When I change the code to ingredient = IngredientSerializer() in the ComponentSerializer class, the representation is nested as intended : { "id": 9, "ingredient": { "barcode": "3218930313023", "name": "Crêpes L'Authentique", "image": "https://static.openfoodfacts.org/images/products/321/893/031/3023/front_fr.16.400.jpg", }, "quantity": 123.0 } But when I try to add a component with an existing recipe and an existing ingredient, I get … -

Design Decision Django Rest Framework - Django as Frontend
I am currently developing my first more complex Web Application and want to ask for directions from more experienced Developers. First I want to explain the most important requirements. I want to develop a Web App (no mobile apps or desktop apps) and want to use as much django as possible. Because I am comfortable with the ecosystem right now and don't have that much time to learn something new that is too complex. I am inexperienced in the Javascript World, but I am able to do a little bit of jQuery. The idea is to have one database and many different Frontends that are branded differently and have different users and administrators. So my current approach is to develop a Backend with Django and use Django Rest Framework to give the specific data to the Frontends via REST. Because I have not that much time to learn a Frontend-Framework I wanted to use another Django instance to use as a Frontend, as I really like the Django Template language. This would mean one Django instance one Frontend, where there would be mainly TemplateViews. The Frontends will be served on different subdomains, while the backend exposes the API Endpoints on … -

How can I use a bult-in validator in the general clean method or the clean method of a field;
I know I can call the validators in the field, but I want to call them in the clean() or clean_field method, because I want to use a combination of them and reuse them in multiple forms. So, I start from: def clean_description(self): description = self.cleaned_data['description'] MinLengthValidator(min_length,'Ensure that {} has at least {} characters.'.format(field_str,min_length))() return short_description but this doesn't work, the Validation Error is not raised. -

How can I call multiple views in one url address in Django?
I'm trying to show forms defined by new_measurement on index.html, but I only manage to get IndexView() to work. I tried various combinations between IndexView() and new_measurement(), but those didn't work out at all. I know that IndexView() doesn't pass anything related to new_measurement(), and new_measurement() isn't called, which is the core of my problem. I'd really appreciate if someone more experienced with Django could tell me what I could, or should do. Thank you. Here's my views.py: from django.shortcuts import render from django.utils import timezone from .models import Measurement from .forms import MeasurementForm from django.views import generic class IndexView(generic.ListView): model = Measurement context_object_name = 'measurement_list' template_name = 'index.html' queryset = Measurement.objects.all() def new_measurement(request): if request.method == "POST": form = MeasurementForm(request.POST) if form.is_valid(): measurement = form.save(commit=False) measurement.measurement_date = timezone.now() measurement.save() else: form = MeasurementForm() return render(request, 'index.html', {'form': form}) urls.py: from django.urls import path from . import views urlpatterns = [ path('', views.IndexView.as_view(), name='index'), ] forms.py: class MeasurementForm(forms.ModelForm): class Meta: model = Measurement fields = ('measurement_value', 'measurement_unit') index.html: {% extends "base.html" %} {% block content %} <h1>Climate Measurement Tool</h1> <h2>Add a new measurement</h2> <form method="POST" class="post-form"> {% csrf_token %} {{ form.as_p }} <button type="submit" class="save">Add</button> </form> <h2>Measurements</h2> {% if measurement_list … -
Error with system for email password resets
I have been having trouble creating a system for resetting passwords using email. I encountered a problem yesterday which I was unable to solve: NoReverseMatch error with password reset emails After reading some of the relevant docs, I tried to replace the views with the class-based equivalents introduced in 1.11 as below: urls.py: from django.contrib.auth import views as auth_views urlpatterns = [ url(r'^$', auth_views.login, name='login'), url(r'^logout/$', auth_views.logout, name='logout'), ## more irrelevant urls here ## url(r'^password/reset/done/$', auth_views.PasswordResetDoneView, name='password_reset_done'), url(r'^password/reset/$', auth_views.PasswordResetView, name='password_reset'), url(r'^password/reset/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', auth_views.PasswordResetConfirmView, name='password_reset_confirm'), url(r'^password/reset/complete/$', auth_views.PasswordResetCompleteView, name='password_reset_complete'), ] This has introduced a new error which is not very helpful: Internal Server Error: /password/reset/ Traceback (most recent call last): File "C:\python\lib\site-packages\django\core\handlers\exception.py", line 41, in inner response = get_response(request) File "C:\python\lib\site-packages\django\core\handlers\base.py", line 187, in _get_response response = self.process_exception_by_middleware(e, request) File "C:\python\lib\site-packages\django\core\handlers\base.py", line 185, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) TypeError: __init__() takes 1 positional argument but 2 were given [11/Feb/2018 12:35:38] "GET /password/reset/ HTTP/1.1" 500 62168 How can I get my system working? -
How would I create my own filter?
I'm trying to query a subset of users based on certain conditions. Filtering by most conditions is relatively straightforward, but some are a bit more complex. For example, here is a function that I'm trying to incorporate into a query filter: def prefs_are_none(profile): none = True if profile.get_faves() or profile.get_choices(): none = False return none I'm not sure how to add that functionality into this query: user_list = Profile.objects.annotate( distance_away=Distance( 'last_location', current_user.last_location ) ).filter(last_location__distance_lte=( current_user.last_location, D(km=200) ), public=True, # additional filters would ideally go here) Here's the model for the Profile which clears up certain the methods used above(get_faves(), get_choices()): class Profile(models.Model): fave1 = models.CharField(max_length=54, blank=True, null=True, verbose_name='Learn A') fave2 = models.CharField(max_length=54, blank=True, null=True, verbose_name='Learn B') choice1 = models.CharField(max_length=54, blank=True, null=True, verbose_name='Teach A') choice2 = models.CharField(max_length=54, blank=True, null=True, verbose_name='Teach B') public = models.BooleanField(default=False, verbose_name='Public') last_location = models.PointField(null=True) objects = ProfileManager() def __str__(self): return self.user.username def get_faves(self): list_of_faves = [self.fave1, self.fave2] return [field for field in list_of_faves if field] def get_choices(self): list_of_choices = [self.choice1, self.choice2] return [field for field in list_of_choices if field] So essentially in the query I'm trying to check, through the get_faves() and get_choices() functions, that a profile does not have either empty--this is what's currently happening in … -

Share objects between users in django
Guys i am very new to django, i have done research but most i have found does not exactly solve my problem . In my application, i want users to be able to share objects created by other users . For example model.py #This a model object users can share def BusinessObjects(models.Model): businessname=models.CharField(max-length=230) businesstype=models.CharField(max-length=230) creator=models.ForeignKey(Users,unique=True,on_delete=models.CASCADE) share=models.ManyToManyField(Users,related-name="sharer",null=True) So a user can create just one object of the businessObjects .And this object can be shared by other users .What is the best way possible to go about this . Creating a view, model which enable users to add objects created by other users .And these shared model objects will be added in to a list which i can pull out and display to the users . I will be very much grateful if you can help me out with hint to go about creating a good model and view to meet up my desire output .Thanks in advance -
