How to get a QuerySet with type of a ForeignKey attribute in Django
I have a simple database model in Django that looks like: class Employee(Model): first_name = models.CharField(max_length=128) last_name = models.CharField(max_length=128) class PrizeDraw(Model): winner = models.ForeignKey( Employee, null=True, on_delete=models.SET_NULL, ) What I want now is a QuerySet of type Employee that contains all the winners of all PrizeDraws. I would have thought that to be fairly straightforward by something something like: def get_queryset(self): return PrizeDraw.objects.exclude(winner__isnull=True).values('winner') However, that doesn't actually return me what I want, instead it returns: <QuerySet [{'winner': (Employee1) }, {'winner': (Employee2) }, etc...]> Which makes sense according to the values() documentation it returns a Dictionary of values. But this doesn't work for me in the rest of the code I need, so I want to select only the second (i.e. value) part of the key-value pair and return that as a QuerySet that just looks like <QuerySet[Employee1, Employee2, etc...]>. How can I select the right value as to get that desired QuerySet? -

Send data to another django template/view after specific process using ajax
I have a page where I load 2 files. After a click to the load button, this page reload to display a major part of the data, allowing the user to modified it. After a click to lunch button, I want to launch the process and I want to send to another page the path of results files to allow the user to download it. My problem is after clicking on lunch button and send data to the other page. I have 2 versions : The first one, send data to the result page, but I do not find a way to take back in the view the data modified by the user, the ajax seems to be ignored because of the type "summit" for the button launch : <body> <section class="bg-light py-5 border-bottom"> <div class="container px-5 my-5 px-5"> <div> <h1 class="display-5 fw-bolder mb-2"> Convert to Dose </h1> <br> </div> <form id="formCTD" action="{% url 'json:convertToDose' %}" method="POST" enctype="multipart/form-data"> {% csrf_token %} ##here some fields to modified one of them following <div class="row gx-5 justify-content-center"> <div class="col-lg-4 col-xl-4"> {% if factors %} <input name="img_path" readonly class="form-control" {{ pathAnalyseForm.img_path }}> {% else %} <input id="btn-submit-form-jsonfile" class="btn btn-lg" {{ formImgFile.imgFile }}> {% endif … -
Django - How to access parent object for passing as URL primary key inside templates?
I have two Django models: class AP(models.Model): room = models.ForeignKey(Room, on_delete=models.SET_NULL, null=True) and class Room(models.Model): name = models.CharField(max_length=20, unique=True) I have passed an object of AP class as ap to the template. In the template, I am trying to create a hyperlink with ID of the room. I am creating hyperlink through the following line: <a href="{% url 'edit_ap' ap.room.id %}">{{ap.room.name}}</a> This is throwing the following error: Reverse for 'edit_ap' with arguments '('',)' not found. 1 pattern(s) tried: ['edit\\-ap/(?P<pk>[^/]+)/$'] The urls.py has the following matching pattern: path('edit-ap/<str:pk>/', views.edit_ap, name='edit_ap'), The hyperlink is working if the primary key is changed from ap.room.id to ap.room, which passes room.name as the primary key to the URL. However, I need to provide ap.room.id as the primary key. I believe it has to do with using two dots in the primary key. Can you please suggest how can I pass ap.room.id as primary key to my URL? Thank you. -

working with SQLSERVER database that doesn't have keys using DJANGO
I'm currently doing an internship at a company, they asked me to build an invoice management web app, the process is a little complicated. First I created the login page, home page and the core elements of every web app. I used PostgreSQL for this, but when I wanted to build the main functionalities of the app, I switched to a copy of their database, they are using SQL Server 2012 and the data is coming from an ERP. The problem is when I have connected to database and use inspect DB to get the tables, I discovered that all the tables in the database don't have a Primary Key or Foreign Key. I asked the IT responsible about this and he told me that the ERP is stocking the data without any keys, it uses another method. I would really appreciate it if someone could help me out of this issue. -
Django - making form which contains two related models
I wonder if it is possible to make a django model based form which will allow to create two models which one will be passed as a foreign key to second one. let we have these models: class Book(models.Model): title = models.CharField(max_length=200) published = models.DateField() def __str__(self): return self.name class Chapter(models.Model): name = models.CharField(max_length=200) number = models.IntegerField() book = models.ForeignKey(Book, on_delete=models.CASCADE) def __str__(self): return self.name I'd like to make a view which will contain BookForm and many ChapterForms somehing like: Book.title = [input] Book.published = [input] and below that (still in the same view) Chapter.name = [input] Chapter.number = [input] Chapter.name = [input] Chapter.number = [input] add more chapters After submitting form, Book and related chapters should be created How can I achive it ? Till now I was just making two views: one for making a Book and second one for chapter which gets created book's id as a parameter in url, but I'd like to make it in one view -
Different methods of Django User model
I have been using Django for 4 5 months now and i have been implimenting users by importing the user class like this example 1: from django.db import models from django.contrib.auth.models import User class Posts(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post_name = models.CharField(max_length=150) desription = models.CharField(max_length=200) image = models.ImageField(upload_to="images/uploads") def __str__(self): return self.desription and i have seen some people use the user model like this : example 2: class Recipe(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) name = models.CharField(max_length=220) description = models.TextField(blank=True, null=True) directions = models.TextField(blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) active = models.BooleanField(default=True) and also like this : example 3: author = models.ForeignKey(get_user_model()) now I have used both example 1 and example 2 for my projects and to mess around in my free time and both seem to work fine , I am wondering what would be the use cases for these different methods and also is there any pros or cons to these methods of using the User Model? -

Django admin site - limit user content on user
admin.py: from django.contrib import admin from .models import Blog admin.site.register(Blog) I have figured out that Django admin serves my needs very well. The only thing I would like to limit is that Users could write/read/edit the Blog applications but for their own entries only. If Alice posts a blog, she can read/write/edit only her posts and not the posts of Bob. Does Django allow anything like this in the admin site or do I need to develop my code? -

Uploading a file in a form group in angular and send it to Django API
I have a form in the front-end having multiple entries, i.e name, email, phone and also a file field entry. A Form group is used to group all these elements in the same form in Angular. There is also a corresponding model in Django, (Using Django Rest Framework). I could not manage to have the file sent to the API, even if the rest of the data is sent correctly and saved on the back-end. First, I am able to upload the file successfully to Front-end, below I log in the console: Second, the object I send is something like this: {"name":"name", "age":49, "email":"email@field.com", "file":File} The File in the JSON is the same file object displayed in the console above. I tested my backend with Postman, I was able to succesfully have the file as well as the other data saved. (I believe the problem to be more on the Front-end side ). Solutions I found for uploading file in Angular used form data (i.e here), these solutions were not convenient as the form consists only of a file, however in my case I have file as well as other data (Form Group). Another thing I tried that did not … -
Django Rest Framework - Filter with logical and
I'm using Django Rest Framework with DjangoFilterBackend to filter through Publications. Every publication can have multiple authors. My api call to filter the api for authors looks like: /api/v1/publication/?author=1&author=2 This gives me every publication that either author 1 or author 2 has been assigned to. Instead I want to only see the publications that both have published. In other words it should be a logic and, not or. My code is the following: models.py class Publication(models.Model): id = models.BigAutoField(primary_key=True) title = models.CharField(max_length=400) author = models.ManyToManyField(Author, blank=False) type = models.ForeignKey( Type, on_delete=models.PROTECT, null=False, default=1) label = models.ManyToManyField(Label, blank=True) date = models.DateField(blank=False, null=False) url = models.URLField(null=True, blank=True) journal = models.CharField(max_length=400, blank=True) bibtex = models.TextField(blank=True) public = models.BooleanField(default=False) updated = models.DateTimeField(auto_now=True) created = models.DateTimeField(auto_now_add=True) file = models.FileField(upload_to=upload_path, blank=True, null=True) class Meta: ordering = ['-date'] def __str__(self): return self.title views.py class PublicationFilter(django_filters.FilterSet): author = django_filters.ModelMultipleChoiceFilter( queryset=Author.objects.all()) class Meta: model = Publication fields = { 'title': ["exact"], 'author': ["exact"] } class PublicationView(viewsets.ModelViewSet): queryset = Publication.objects.prefetch_related( 'author', 'label').select_related('type') serializer_class = PublicationSerializer filter_backends = [DjangoFilterBackend, SearchFilter, OrderingFilter] filterset_fields = ['title', 'date', 'journal', 'label', 'author'] search_fields = ['title'] ordering_fields = ['date', 'title'] serializers.py class PublicationSerializer(ModelSerializer): type = TypeSerializer(read_only=False, many=False) label = LabelSerializer(read_only=False, many=True) author = AuthorSerializer(read_only=False, many=True) class … -
Django proxy model is visible on admin site but not showing up in permissions section of the production admin site
Locally I can see the proxy model on the admin site and permissions are visible in the permission section and can be assigned to different users. In production I can see the proxy model on the admin site but permissions are not visible in the permission section and therefore cannot be assigned to different users.

how to understand if the env is activated in a django project
I am just starting to learn django and I am facing the set-up phase. In particular I'd like to ask how to recognize if the virtual environment is activated or not. I know that I can use the command "pip freeze" but in all the tutorial that I am following , when the venv is activated, I can see the vevn name in brackets in the terminal command line. I can correctly activate the venv with the source command and check via the pip freeze command but I have no indication in the command line. I am on a Mac/OS (chip mac) and using python3 thank you -
