Query in query in django?
I'm trying to achieve a query but I'm just unable to do it. I have 3 entities here: Clients: class Client(LogsMixin, models.Model): """Model definition for Client.""" company_name = models.CharField("Nombre de la empresa", max_length=150, default="Nombre de empresa", null=False, blank=False) user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) Courses: class Course(LogsMixin, models.Model): """Definición del modelo de Proveedor.""" name = models.CharField("Nombre del curso", null=False, default="", max_length=200) Consumptions: class Consumption(LogsMixin, models.Model): """Definición del modelo de Consumos""" client = models.ForeignKey('authentication.Client', verbose_name=("Cliente"), null=True, default=None, on_delete=models.SET_DEFAULT) course = models.ForeignKey(Course, verbose_name=("Curso"), null=True, default=None, on_delete=models.SET_DEFAULT) I want to get a list with the 10 most sold courses for the client that visit the page. I want to show the client the name of the course and the number of consumptions that he has done with that course. In every consumption there is a course and a client associated. Could someone give me a hand? -
How to create two object instances from two different models with a single POST request?
I am learning the Django-Rest Framework. I want to create an object instance for both my Story model and my File model with a single post request. So the incoming data contains a title and a file. I want then to create a story object with a title and the image field contains a reference (fk) to the id of the file instance. In the File model a own instance of File is created with the incoming file data. # File Model class File(models.Model): file = models.FileField(upload_to='audio_stories/', null=True, default='some_value') # Story Model class Story (models.Model): title = models.CharField(max_length=100,blank=True) image = models.ForeignKey(File,on_delete=models.CASCADE, blank=True, default=None) # Story Serializer class StoryCreateUpdateSerializer (serializers.ModelSerializer): image = serializers.FileField() class Meta: model = Story fields = ('title','image') def create(self, validated_data): image = validated_data.pop('image') title = validated_data.pop('title') image_instance = File.objects.create(file=image) story_instance = Story.objects.create(title=title, image=image_instance) return story_instance # File Serializer class TestFileSerializer (serializers.ModelSerializer): class Meta: model = File fields = ('__all__') If I send the formdata via Postman to my server it responses with "image": ["This field is required."]. If this is an obvious mistake, I apologize in advance. I am grateful for any clarification. -
Django - Implement "Remember me" after login
Could you please point me to the right direction of how to implement Remember me in my website. I read a couple of articles of how to implement but i'm more confused than point me to the right direction. I've configured the following: forms.py first_name = forms.RegexField(regex=r'^[a-zA-Z]+$', max_length=30, label=_("first name"), error_messages={'invalid': _("Wrong First Name, use only letters")}) last_name = forms.RegexField(regex=r'^[a-zA-Z]+$', max_length=30, label=_("last name"), error_messages={'invalid': _("Wrong Last Name, use only letters")}) email = forms.EmailField(required=True) remember_me = forms.BooleanField(required=False) class Meta: model = User fields = ['username', 'first_name', 'last_name', 'email', 'password1', 'password2'] views.py def loginPage(request): if request.user.is_authenticated: return redirect('index') else: if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') remember_me = request.POST.get('remember_me') user = authenticate(request, username=username, password=password) if user is not None: login(request, user) if not remember_me: request.session.set_expiry(0) return redirect('index') else: messages.info(request, 'Username OR password is incorrect') context = {} return render(request, 'members/login.html', context) login.html <div class="form-group custom-control custom-checkbox"> <input type="checkbox" class="custom-control-input" name="remember_me" id="remember_me"> <label class="custom-control-label" for="remember_me">Remember me</label> <a class="tdu btn-fpswd float-right" href="#">Forgot Password?</a> </div> Of course above code doesn't work.

Factory Boy: how to set conditional SubFactory() attribute depending on params
I got a Customer model which is related to a Company model. I'd like to give my factory the possibility to use a given company (if I need several customer from the same company). I thought to use the inner class Params to achieve that, but I got an issue using LazyAttribute and SubFactory together. Here is my factory: class CustomerFactory(UserFactory): """ To be valid, customer needs to belong to one of these groups: - manager - regular This can be achieved using the `set_group` parameter. Example: manager = CustomerFactory(set_group=manager_group) """ @lazy_attribute def _company(self): if self.use_company: return self.use_company else: return SubFactory('rdt.tests.factories.CompanyFactory') class Meta: model = Customer class Params: use_company = None @post_generation def set_group(self, create, extracted, **kwargs): if extracted: self.groups.add(extracted) I thought to use the factory as: c1 = factories.CustomerFactory(use_company=my_company) c2 = factories.CustomerFactory() I got ValueError. It seems I can't get the parameter value 'use_company' in the factory. Anyway my factory throws a ValueError. -

Return nested JSON from Models with relations in Django
models.py (simplified) class Author(models.Model): name = models.CharField(max_length=255) def __str__(self): return self.name def get_books(self): return Book.objects.filter(author=self.pk) class Book(models.Model): name = models.CharField(max_length=255) pages = models.IntegerField() author = models.ForeignKey(Author, on_delete=models.CASCADE) def __str__(self): return f'{self.name} from {self.author}' class Paragraph(models.Model): name = models.CharField(max_length=255) book = models.ForeignKey(Book, on_delete=models.CASCADE) def __str__(self): return f'{self.name} from {self.book}' I want to return all the instances in a json file with this structure: [ { "name": 'Dumas', "books": { "name": "The count of Montecristo", "paragraphs": { "name": "paragraph_name_1", }, { "name": "paragraph_name_2", }, { "name": "The three Musketeers", "paragraphs": { "name": "paragraph_name", }, ] What I tried: serializers.py class AuthorSerializer(serializers.ModelSerializer): books = serializers.CharField(source='get_books', read_only=True) class Meta: model = Author fields = ['name', 'books'] This add the books key but the value is the string representation of the istances of Book (of course), how I make the value being the serialized istances of Book? I have created a BookSerializer. Notes: I know that I can created a nested json by creating a serializer for Paragraph with depth = 2 but this will include fields I don't want (like pages in Book) and the json structure will be totally different. -
How to Render Django ForeignKey relation on Datatables Serverside
Im stuck for days, im using plugin django-datatables-view and I need to render ForeignKey related value in serverside datatables, it's like: {{data.pasien_id.name}} in typical django template. but that way not work with serverside datatables, and there is no documentation anywhere to achieve that. the code shown below.

Why after moving a .js script from html to .js file, it does not load the values?
I have a dropdown box which whenever I change its values, a js script forwards its responses to another dropdown. This script works when is inside the .html file, but once I move it to a seprate .js file it does not work. this is the code: $("#id_subtag-tags").change(function () { var tagId = $(this).val(); // get the selected tag ID from the HTML input console.log(tagId); $("#displaytags").html(''); $.ajax({ // initialize an AJAX request url: '{% url "ajax_load_subtags" %}', // set the url of the request (= localhost:8000/app/ajax/load_subtags/) data: { 'tags': tagId // add the tag id to the GET parameters }, success: function (data) { // `data` is the return of the `load_subtags` view function $("#id_subtag-subtags").html(data); // replace the contents of the subtags input with the data that came from the server } }); }); There is another function in the same file which is properly is being loaded to that html file, so I think problem is not in loading. I don't know what is causing this bug. The error I receive is: GET failed, ajax_load_subtags 404 (Not Found), url.py: path('myapp/post/ajax/ajax_load_subtags', load_subtags, name='ajax_load_subtags'), -

Bitbucket-Pipeline: How to automatically build and deploy a Django app docker image to Heroku or VPS
I'm new to docker and bitbucket pipelines so things a bit confusing at the moment when it comes to the practical implementation. I am looking for an existing walk-through (in a forum, book, article etc) about: "Bitbucket-Pipeline: How to deploy a docker image to Heroku" or, even better a source dealing with: "step by step: how to dockerize and deploy your django app via bitbucket pipelines to heroku and vps" I found one online using "Springbook" link and a shell script but I couldn't generalise it into django and docker-compose. Some posts say you cannot use docker-compose in bitbucket, and do I need to use a shell script? Any type of help or direction would be much appreciated at this stage of learning. -

Django-oscar manage users via dashboard
I'm not able on a fresh project with django-oscar to manage users using the dashboard(editing/deleting) - as superadmin I'm able only to see user details and also send reset password email.

It's an easy way to handle editing/deleting users via the oscar dashboard? I can see the solution as creating a custom view for that but then I think having it just in the Django Admin will more efficient :) -

How to get and return a model instance by id using Django ModelForm when there is too many instances?
I have a ModelForm for an Inline and I am trying to accept an id of an instance and then get the instance and 'return it to the field' as the field is a ForeignKey field. I cannot use (Model)choicefield as there are thousands of instances which means it takes ages to load. Neither I can take for example a slice of the most recent objects and choose from those as it results in a cannot filter the queryset once a slice has been taken error. I have tried working around with the save method but I couldn't make it so far. (but it is my bet that this will be the way to go) I would like the form to take three ids and then get those instances by model.objects.get(id=id) and then somehow create a new instance. the code looks as follows; class AgregatorCrossSaleProductForm(forms.ModelForm): IsShown = forms.BooleanField(required=False) ParrentProductId = forms.IntegerField() ChildProductId_id = forms.IntegerField() CrossSaleProductTypeId = forms.IntegerField() class Meta: model = AgregatorCrossSaleProduct exclude = [] class AgregatorCrossSaleProductInline(admin.TabularInline): model = AgregatorCrossSaleProduct form = AgregatorCrossSaleProductForm ...

Why js script does not load ajax response? [duplicate]
I have a dropdown box which whenever I change its values, a js script forwards its responses to another dropdown. This script works when is inside the .html file, but once I move it to a seprate .js file it does not work. this is the code: $("#id_subtag-tags").change(function () { var tagId = $(this).val(); // get the selected tag ID from the HTML input console.log(tagId); $("#displaytags").html(''); $.ajax({ // initialize an AJAX request url: '{% url "ajax_load_subtags" %}', // set the url of the request (= localhost:8000/app/ajax/load_subtags/) data: { 'tags': tagId // add the tag id to the GET parameters }, success: function (data) { // `data` is the return of the `load_subtags` view function $("#id_subtag-subtags").html(data); // replace the contents of the subtags input with the data that came from the server } }); }); There is another function in the same file which is properly is being loaded to that html file, so I think problem is not in loading. I don't know what is causing this bug. The error I receive is: GET failed, ajax_load_subtags 404 (Not Found),
