Django: Combine two count annotations from two filter queries
I am computing some statistics based on two different filters, but I'm not sure how I can combine both results into a single QuerySet. My code looks like this: qs1 = User.objects.filter(c1).annotate(count1=Count("id")) qs2 = User.objects.filter(c2).annotate(count2=Count("id")) I would like to create a third queryset, qs3 which has both count1 and count2. Basically I want to left join on User.id but I can't find a straightforward way of doing that. -
Django: capture authorization token from another service
I'm trying to capture an authentication token from another service authenticator. In summary, I have a form login that serve client with two options to sign in, throw the normal login, or a link to a second authenticator service which will redirect to a particular form page. Once the user is signed, this second authenticator service will redirect back to my application, with a token as param. I would like to include a kind of listener in my application (small script), in a way that when this redirect happen, I could capture and validate the token, finally, authenticate the user in the local django application. -
Django Rest Framework Viewsets Count Foreign Key
I am trying to add a additional field to my modelviewset. For example, if I have 1 parent and 3 children objects, I would like parent viewset json to look like. To get the count of the children I can do something like children = Child.objects.filter(parent.id=).count(), but I'm not sure how to get the parent id inside the view set. [ { "id": 1, "name": "parent1", "child_count": 3 } ] models.py class Parent(models.Model): name = models.CharField(max_length=100) class Child(models.Model): name = models.CharField(max_length=100) parent = models.ForeignKey("Parent", on_delete=models.CASCADE) views.py class ParentViewSet(viewsets.ModelViewSet): serializer_class = ParentSerializer children = Child.objects.filter() # ?? def get_queryset(self): queryset = Parent.objects.all().annotate(child_count=) # ?? return queryset serializers.py class ParentSerializer(serializers.ModelSerializer): child_count = serializers.IntegerField() class Meta: model = Parent fields = ["id", "name", "child_count"] -
How to make django boolean field true using a method in django models
I working on an e-commerce website I have the field about new arrivals so any product which is created in the last 30 days should be listed as a new arrival. In my models, I have a boolean field as is_new and the default value is false and I made a method to check the date whether the product is included in the new arrival list or not. but in my method new_arrival when I return self.is_new I get an invalid syntax. class Product(models.Model): name = models.CharField(max_length=200) description = models.TextField() price = models.IntegerField() picture = models.ImageField(upload_to='picture/') is_popular = models.BooleanField() is_cart = models.BooleanField() is_arrival = models.BooleanField(default=False) created_date = models.DateTimeField(aut_now_add=True) def new_arrival(self): if self.created_date >= self.created_date - self.created_date.timedelta(days=30): return self.is_new=True else: return self.is_new = False -
how to update value the field in model django of an object that belongs to a class that inherits from another abstract class?
class BaseModel(models.Model): created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: abstract = True class PublicModel(models.Model): public_id = models.UUIDField(default=uuid.uuid4, editable=False, db_index=True, unique=True) class Meta: abstract = True class People(BaseModel): first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) class Address(BaseModel): postal_code = models.CharField(max_length=255, null=True) public_place = models.CharField(max_length=255, null=True) class Contact(BaseModel): email = models.EmailField() phone = models.CharField(max_length=255, null=True) class Member(BaseModel, PublicModel): name = models.CharField(max_length=255) person = models.OneToOneField(People, on_delete=models.PROTECT) class Meta: abstract = True class Hub(BaseModel): description = models.CharField(max_length=255) address = models.ForeignKey(Address, on_delete=models.PROTECT) contact = models.OneToOneField(Contact, on_delete=models.PROTECT) class Partner(Member): hub = models.ForeignKey(Hub, on_delete=models.PROTECT, null=True) When updating a People or Hub object I would like the updated_at the Partner field also updated to reflect the current time of this modification. As it is, when updating a People or Hub object only its field updated_at has the updated time. What is the best approach to doing this? At the moment I am updating in a way that I think is very bad. Forcing Partner object update by passing a value to public_id so that updated_at has its updated value. Partner.objects.update_or_create(id=partner.id, defaults={'public_id': kwargs['public_id']}) -

Django ModelForm: changing the format of a dropdown list with initial value
I created a form in Django with ModelForm: class FormulariMostra(ModelForm): class Meta: model = Sample fields = ("name", "sample_id_sex", "pools",) pools is a foreign key (m2m relationship). In my views.py I added an initial value for the field pools: formulari_mostra=FormulariMostra(initial={'pools':1}) In the form the options for the field pools are ordered by id in descending order. My problem is that the dropdown list appears like this: With the initial (default) value highlighted and what I want is that the value with the id with the highest number appears the first one: Is there a way to do this maintaining the initial value? Or to hide this specific value? -

Django pass id from one model to another's foreign key
I have a User model and Employee model which stands for additional info about user, it has one to one field relation with User instance.

Using apscheduler to run Django serializer code every 15 minutes and updates it's data
using serializers I wrote some code that will ssh to different machines and return some information about these machines. Every time I refresh my page, the code will ssh to the system and return real time data. After noticing how long it takes to ssh to the machines to return data and some other issues, I figured this approach is not the best. I would like to save whatever result I git from the ssh in a database/cache and retrieve this data when I refresh the page from the database/cache. I thought of using an apscheduler and have the serializer update it's data every 15 minutes instead of every time I refresh the page (ssh once every 15 minutes). I am not sure if this will work or if there are better ways to achieve this. I would be thankful if you guys give some pointers. Currently my serializer results are not saved in the database. So to achieve this do I need to save the results of the serializer in the database? and will apscheduler do the trick? -

Django decorator to redirect to same page?
When a user tries to access a non permitted page, whats the right thing to do ? First option: Redirect to the same page they came from Second Option: Redirect to error page saying permission denied or not found Third Option: Redirect to login page I have created a decorator: from django.contrib.auth.decorators import user_passes_test from django.contrib.auth import REDIRECT_FIELD_NAME def is_student(function=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url=None): actual_decorator = user_passes_test( lambda u: (u.is_authenticated and u.role == 'role1'), login_url=login_url, redirect_field_name=redirect_field_name ) if function: return actual_decorator(function) return actual_decorator So the above works and redirects to login if we give login_url !

I have created a new update view but I keep getting the error Page not found 404 - The current path, post/118/build-log/54/update/, matched the last one. template: {% extends "blog/base.html" %} {% load crispy_forms_tags %} {% block content %} <a>Update</a> {% endblock content %} view: class BuildLogUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = BuildLog form_class = BuildLogForm template_name = 'buildlog_update.html' def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def test_func(self): BuildLog = self.get_object() if self.request.user.id == BuildLog.author_id: return True return False url: path('post/<int:pk>/build-log/<int:pkz>/update/', BuildLogUpdateView.as_view(), name='build-log-update') most of what i found online was talking about the trailing / on the url but it did not make a difference for me urlpatterns: urlpatterns = [ path('', views.home, name='blog-home'), path('user/<str:pk_user>/', views.UsersCarsPosts, name='user-posts'), path('post/<int:pk>/', views.DetailPostView, name='post-detail'), path('post/<int:post_pk>/comment/<int:pk>/reply/', CommentReplyView.as_view(), name='comment-reply'), path('post/new/', views.createPostView, name='post-create'), path('post/<int:pk>/update/', PostUpdateView.as_view(), name='post-update'), path('post/<int:pk>/delete/', PostDeleteView.as_view(), name='post-delete'), path('about/', views.about, name='blog-about'), path('allcars/', views.allCarsView, name='all-cars-url'), path('ajax/allcars/', views.loadModels, name='ajax-allcars'), path('ajax/load-models/', views.loadModels, name='ajax'), path('my-profile/', views.myProfile, name='my-profile'), path('post/<int:pk>/build-log-form/', views.buildLogCreate, name='build-log-form'), path('post/<int:pk>/build-log/<int:pkz>/', views.BuildLogDisplay, name='build-log-view'), path('post/<int:pk>/build-log/<int:pkz>/delete/', views.BuildLogDelete, name='build-log-delete'), path('post/<int:pk>/build-log/<int:pkz>/update/', BuildLogUpdateView.as_view(), name='build-log-update') ]
