Django 3 List View objects not displaying in template with if statement. Please help this Django newbie
I'm trying to create a news site with structure like: Master Archive (contains all daily issues of the news publication) Issue (a new one each day with unique articles) Article (related to one Issue) I'm facing a problem where the articles in an issue are not displaying on a Django template (issue_details.html) that's supposed to simply list all articles that are related to an issue. Any suggestions? I'm new to Django and my approach to this may not be best-practice, but things seem to be working other than this problem. articles/views.py from django.shortcuts import render from django.views.generic import ListView, DetailView from .models import Article class IndexView(ListView): model = Article template_name = 'index.html' class ArticleDetailView(DetailView): model = Article template_name = 'article_detail.html' context = { 'details': Article.body } issues/views.py from django.shortcuts import render, HttpResponse from django.views.generic import ListView from .models import Issue, IssueDetails class IssueView(ListView): model = Issue template_name = 'issues.html' slug_url_kwarg = 'slug' slug_field = 'slug' context = { 'issue_title' } issue_view = IssueView.as_view() # List of Articles in a Issue class IssueDetailsView(ListView): model = IssueDetails template_name = 'issue_details.html' slug_url_kwarg = 'slug' slug_field = 'slug' context = { 'title' } issue_details_view = IssueDetailsView.as_view() def detail(request, slug): q = IssueDetails.objects.filter(slug__iexact = slug) … -

Using Django Models to assign HTML div through jQuery
for the last few days I've been trying to create a method in jquery using django models and I have found myself to be very out of my depth and would appreciate and explanation I can get. So currently I have a django model that has the following information : name, date, location, semester. I use the first 3 pieces of information in displaying my html, however, I want to use 'semester' to see what div tag my items go into. The semester tag can either return 'Fall' or 'Spring' values is there a way I can use this to assign the components to the correct div. So if semester is Fall then it should go into the div with the id 'fall-races' and if its spring it should go to 'spring-races' Currently I only have a jquery working where I get all the elements and assign it to the other div. Thank you for your help and any possible advice. <div class="flex-column"> <div class="header shadow-lg"> <h1 class="text-center py-3"> Fall Schedule </h1> </div> <div id="fall-races"> {% for race in race %} <div class="regatta-card my-2 mx-2 "> <h2 class="center-text py-2">{{ race.date }}</h2> <h1 class="text-center my-2">{{ race.name }}</h1> <h3 class="text-center mb-3">{{ race.location}}</h3> … -

Accessing Choices Value of PositiveSmallIntegerField in Django Template
I have a model like this: class SomeModeL(Model): MODEL_TYPE = ( (0, 'Type1'), (1, 'Type2'), (2, 'Type3') ) model_type = PositiveSmallIntegerField(choices=MODEL_TYPE) Now, I passed in an instance of the model into context and want to access the model_type, specifically the String, such as 'Type1' So, in the template, i do this: {{ some_model.model_type }} but this returns the integer, not the string. How do I get the string? -
Python / Django - edit render output
I'm new to python and I have the following issue. I have a Counterpart database with two boolean fields that are "is_client" and "is_supplier".

Django Bootstrap Carousel wont ride
This is my first project with building a website. I have been following these tutorials. I browsed through the Bootstrap components page and found a Carousel method (slides only) that I wanted to use. I copied and pasted it into my code. The first image shows up which is correct, because it is active, but the Carousel does not slide to the next image. The first code block shows a summed up version. The second block of code is after running python manage.py runserver. The third block of code is when I open the IP address link. I am not sure what I am doing wrong. Any suggestions?

Django Rest Framework change serializer foreign key field's queryset based on user
Suppose I have these models: class Department(Model): ... class Building(Model): department = ForeignKey(Department, on_delete=CASCASE, related_name='buildings') staff = ManyToManyField(User) and I have 2 serializers for these models class DepartmentSerializer(ModelSerializer): class Meta: model = Department # how do I change this list of buildings accordingly to the user making the request? fields = (..., 'buildings') class BuildingSerializer(ModelSerializer): class Meta: model = Buiding fields = '__all__' What I want to do is, when a user requests for a Department, e.g. via a ViewSet, the result comes back is JSON data from the serializer, but the buildings field only contains the buildings that the user works in. So for example, user 'alice' and 'bob' both work in department 1. Department 1 consists of 5 buildings, [1, 2, 3, 4, 5]. However, alice only works in buildings 1 and 2, while bob works in buildings 3 and 4. And when alice requests to get department 1 data, she should get back { "id": 1, ... "buildings": [1, 2] } and if bob requests for department 1 as well, he should get back { "id": 1, ... "buildings": [3, 4] } Is there a way to do that using Django Rest Framework?

Pycharm no longer runs python scripts inside django project - not finding settings
I tried changing the root directory for the project (to match a productions servers structure so relative importing matches) and managed to screw up pycharm to the point that I can't even run scripts on new django projects. I imagine this has to do with how the venv is configured in pycharm, but have tinkered for hours changing relative import names and can not figure it out. I vaguely remember having to change the environment variables in the pycharm configs, but can't find anything like that when googling. Thank you in advance for any and all help.

Django query omitting expected results
I must perform a query on a large database with a somewhat intricate modeling, which I will try to abridge below: class ScreeningItem(models.Model): # other fields receivedItem = models.OneToOneField(ReceivedItem, null=True, on_delete=models.SET_NULL) class ReceivedItem(models.Model): # other fields dossier = models.ForeignKey(Dossier, null=True, on_delete=models.SET_NULL) class Dossier(models.Model): # other fields subjects = models.ManyToManyField('SubjectTypes', through='Subjects', through_fields=('dossier', 'subjectType')) class Subject(models.Model): main = models.BooleanField(null=True) dossier = models.ForeignKey(Dossier, null=True, on_delete=models.SET_NULL) subjectType = models.ForeignKey(SubjectType, null=True, on_delete=models.SET_NULL) class SubjectType(models.Model): # other fields name = models.CharField(max_length=255, null=True, blank=True) parent = models.ForeignKey('self', null=True, on_delete=models.SET_NULL) Now, the problem is that I must find in ScreeningItem table items when the far, far away related field SubjectType.name contains specific words. No, worse. As you can see below, there's a parent-child self reference in that model, and I must look for those specific words in the related SujectType, its parent, and its grandparent, in case they exist.

Pass value from url request with Django generic detail view
From the GenericList, when clicking on one I redirect towards url(r'^machine/(?P<pk>[0-9]+)$', MachineDetailView.as_view(), name='machine-detail'), Where class MachineDetailView(DetailView): model = Awg template_name = 'gui/machine_detail.html' context_object_name = 'last_entry' ordering = ['-timestamp'] However what I need is to fetch AWG records where machine.id is foreign key in AWG's. In my mind it would look like that: class MachineDetailView(DetailView): last_entry = Awg.objects.filter(machine_id=Machine.objects.filter(id=pk).first()).first() model = Awg template_name = 'gui/machine_detail.html' context_object_name = 'last_entry' ordering = ['-timestamp'] That doesn't work because I don't know how to get that pk that is in the url requested.

What does it mean by "For populating columns a and b, add the code in this model" in Django?
I have a requirement at work where the columns of a paginated table in the UI should be: Person ID First Name Last Name Person Status: Latest Status of Person Full Name Is Adult (Adult if person > 18 years of age) Profile Pic (Icon) if available Now, I have three models, namely: Person: Fields first_name, last_name, date_of_birth, gender, profile_pic (Nullable), created_at, modified_at PersonStatus: Fields person (FK Person), status_text, created_at, modified_at FormulaFields: formula(TextField that is able to store python code of up to 2000 characters), column_number (Integer >=4), created_at, modified_at I'm unclear what FormulaFields does, will need to clarify on Monday but want to finish it, or at least do something. For populating columns 5 and 6, I need to add the code in FormulaFields model. The column number of Formula Field should map with the Column number of above table (at the top, person ID to profile_pic). The above line confuses me, "For populating columns 5 and 6, add the code in FormulaFields model". To show the column full name and is adult, I need to add them as columns in the FormulaFields model, or do I add a method in FormulaField that will calculate them (but FormulaField doesn't …
