Working with checkboxes and querying the database in Django
My goal is to create a page that lists all the courses available in the database and have the user select which courses they would like to be a tutor for. I have a CustomUser model, a courses model, and finally a TutorTeachesCourse model that takes user and courses as foreign keys. # model.py from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): is_tutee = models.BooleanField(default=False) is_tutor = models.BooleanField(default=False) class Courses(models.Model): course_name = models.CharField(max_length=100, null = False) course_number = models.CharField(max_length=100, null = False) department = models.ForeignKey(Department, on_delete=models.CASCADE) course_description = models.CharField(max_length=1000, blank=True) objects = models.Manager() class TutorTeachesCourse(models.Model): tutor = models.ForeignKey( CustomUser, on_delete=models.CASCADE, limit_choices_to=models.Q(is_status=True)) course = models.ForeignKey(Courses, on_delete=models.CASCADE) objects = models.Manager() class Courses(models.Model): course_name = models.CharField(max_length=100, null = False) course_number = models.CharField(max_length=100, null = False) department = models.ForeignKey(Department, on_delete=models.CASCADE) course_description = models.CharField(max_length=1000, blank=True) objects = models.Manager() # forms.py class EditTutoredCourses(ModelForm): class Meta: model = TutorTeachesCourse fields = [] # not sure what to do here... # views.py def edit_tutored_courses(request): user = request.user if request.method == 'POST': #something about forms? form = EditTutoredCoursesForm(request.POST, instance=user) if form.is_valid(): user = form.save() messages.success(request, 'Success!') return redirect(reverse('view_profile')) else: form = EditTutoredCoursesForm(instance=user) course_list = Courses.objects.all() self_courses = TutorTeachesCourse.objects.filter(tutor=user) context = { 'form' : form, 'course_list': course_list, 'self_courses' : self_courses, } return … -

Render django.forms.fields.ChoiceField object
In my Django Project I have the following Problem: I would like to have a dynamic Django form. In the first step the user is asked something by the first form.

Django Rest Framework objects referenced using multiple keyword objects

Unable to save null to ForeignKey in an intermediate model - Django
My use case is, there is a Workshop and there are multiple positions (Workshop_Position) in it. For any position there will be multiple applications. The workshop owner has to approve an application for the user to be a team_member in the workshop. I am using a ManyToMany relationship for this, see below my models. class Workshop(models.Model): ... team_members = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='member_in_workshops', through='Membership') ... class Workshop_Position(models.Model): position_heading = models.CharField(max_length=100, null=False, blank=False) ... class Membership(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='membership', blank=True, null=True, on_delete=models.CASCADE) position = models.ForeignKey('Workshop_Position', related_name='membership', on_delete=models.CASCADE) workshop = models.ForeignKey('Workshop', related_name='membership', on_delete=models.CASCADE) date_joined = models.DateTimeField(auto_now_add=True) class Meta: unique_together = ("position", "user") So when a new position is created, I am saving the position to the Workshop_Position table and attempting to save the workshop the position belongs to with a null user into the Membership. I need to save this with a null user because there are going to be multiple applications to a Workshop_Position and the owner selects which user gets into the position. I am doing the below, { "user": " ", "position": "3", "workshop": "1" } But I get an error when I try to save the above to the Membership model. "user": [ "This field may not be null." … -
Why use @apiDefine together with @apiPermission in apiDocjs?
I am using apiDocjs in order to document my API. I have to define some Permissions, but when I simply use @apiPermission, this line just appears as plain text. When I add @apiDefine (https://apidocjs.com/#param-api-define) prior to that - I get no error, but it does not seem to change anything. I thought it would at least make it appear as a text with heading in HTML. So, what is the sense in using @apiDefine prior to @apiPermission? I am a beginner, and I cannot see any difference with or without @apiDefine - both HTMLs look the same to me. Here is a part of the code: class ArticleList(generics.ListAPIView): """ @apiDefine Authenticated user Only logged in users can use this functionality """ """ @api {get} / Retrieve all articles @apiName GetArticles @apiGroup Articles @apiPermission Authenticated user @apiSuccess {Object[]} articles List of articles. @apiSuccess {Number} id ID of the article @apiSuccess {String} author Name of the author @apiSuccess {String} title Title of the article @apiSuccess {String} body Text of the article @apiSuccess {Date} created_at Date when the article was published And the image below shows how the HTML looks like.

Methods from a single view to different endpoints: keep APIs for HTML and for JSON separated (Django Rest Framework)
Could you help suggesting how to keep coding style organised to keep endpoints from HTML and JSON separated, in Django Rest Framework ? In Flask I am used to keeps endpoints for serving Json, and ones for serving HTML, separated, like: @application.route('/api/') def api_root(): #... return jsonify({'data' : data}) and @application.route('/home/<string:page>/', endpoint='page_template') #... return render_template(template, page) And so I could serve the APIs like: /api/page => serve the json for the page, say for AJAX etc. /page => serve the corresponding html page In Django RF, I read that a ModelViewSet can serve both. So I could keep everything in one place. However, when I come to map views on the router, I would have all the endpoint served respect the path related my model, they would be all sub-path of /api Could you help in advising a good coding practice to make use of ModelViewSet, and route endpoints for html separated from APIs ? This is the example Im working on, my doubts are in comments: from rest_framework import viewsets from rest_framework import generics from rest_framework.decorators import action from rest_framework.response import Response from .serializers import PersonSerializer from .models import Person class PersonViewSet( viewsets.ModelViewSet): queryset = Person.objects.all().order_by('name') serializer_class = PersonSerializer … -

Django receive a signal when a model value gets changed from a different application or when manually edited in database
I'm currently in a peculiar situation where I am not allowed to use a new database even though the product owner wants a new and improved application. This means that my new application will have to work with the old database. This database doesn't use foreign key constraints, which makes the usage of modules such as Django tables 2 nearly impossible. The solution I thought up is the following: Add in an extra foreign key field to required tables Users in the old app change an id of sorts, let's say team id of a news article Django app sees this change, finds the correct team model and links that team model to the foreign key field What I've tried so far to achieve this: Add in a custom save method to my model. This does work when I change the model with a view or CLI, but doesn't do anything when I manually change a value in the database or use a different application to change any values. class Team(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=100) intra = models.ForeignKey(Intra, on_delete=models.DO_NOTHING) def save(self, force_insert=False, force_update=False): print("test") The next solution I tried is using a receiver.

How can I create new 'draft' object with class based UpdateView before form filling?
I have a product model that has a lot of field. When user click to "Create New Product" I want create new object (just create object that it has id, seller, draft status), and show blank form. Because I want to use Ajax asyncronous upload to this object. User fills the object's other fields (like upload images) and save. Also user should be able to edit own draft products on own dashboard. First problem: I used UpdateView, but If I override get_object method and I click "Create New Product", django calls twice this method and create two object?! I want call just one time. Second problem: When users wants to edit draft items, they go to dashboard and edit someone. Should I create new class-based view for this or can I use same view for both operation? Maybe I can add get_or_create method to my get_object method, is It possible? my model: class Product(models.Model): seller = models.ForeignKey("auth.User", on_delete=models.CASCADE, verbose_name="Seller", default=None) category = models.ForeignKey("Category", on_delete=models.CASCADE, verbose_name="Category Name", blank=True, null=True) title = models.CharField(max_length=50, verbose_name="Product Title", blank=True, null=True) status = models.IntegerField(choices=((x.value, x.name.title()) for x in Status), default=Status.TASK) images = models.ManyToManyField("ProductImages", blank=True, null=True) my class-based view: class ProductCreateViewTest(LoginRequiredMixin, UpdateView): template_name = 'product/add.html' form_class = … -
