How to retrieve a list of objects (including ForeignKey Field data) in django (DRF) without significantly increasing DB call times
I have three models in a django DRF project: class ModelA(models.Model): name = .... other fields... class ModelB(models.Model): name = .... other fields... class ModelC(models.Model): name = .... model_a = FKField(ModelA) model_b = FKField(ModelB) I was using the default ModelViewSet serializers for each model. On my react frontend, I'm displaying a table containing 100 objects of ModelC. The request took 300ms. The problem is that instead of displaying just the pk id of modelA and ModelB in my table, I want to display their names. I've tried the following ways to get that data when I use the list() method of the viewset (retreive all modelc objects), but it significantly increases call times: Serializing the fields in ModelCSerializer class ModelCSerializer(serializers.ModelSerializer): model_a = ModelASerializer(read_only=True) model_b = ModelBSerializer(read_only=True) class Meta: model = ModelC fields = '__all__' Creating a new serializer to only return the name of the FK object class ModelCSerializer(serializers.ModelSerializer): model_a = ModelANameSerializer(read_only=True) (serializer only returns id and name) model_b = ModelBNameSerializer(read_only=True) (serializer only returns id and name) class Meta: model = ModelC fields = '__all__' StringRelatedField class ModelCSerializer(serializers.ModelSerializer): model_a = serializer.StringRelatedField() model_b = serializer.StringRelatedField() class Meta: model = ModelC fields = '__all__' Every way returns the data I need (except … -
How to use Django slugs creatively
In my frontpage.html. I have two buttons that link to the different categories of products I have I was using a for loop to get the slug needed for the URL link In the button, but this causes issues because it renders two buttons for each category i created in the models. My question: Is there a way for Django to only use one of these category slugs so I can specifically pick which URL it will render? I attached a picture of the frontpage.html file notice the for loop I am using to get the category slug that is being used to render the correct detail page. a for loop won't work since i have multiple categories HTML {% for category in menu_categories %} <a href="{% url 'category_detail' category.slug %}">Get Started</a> {% endfor %} models.py for categories class Category(models.Model): title = models.CharField(max_length=255) slug = models.SlugField(max_length=255) ordering = models.IntegerField(default=0) Here is the models.py as well.

Multiple For Loops Django
I have the following two models ASPBoookings and Athlete. The Athlete model is linked to the ASPBookings model by the foreign key named athlete. I am trying to create a loop that will cycle through all of the bookings in the ASPBooking table and find out which is the most recent booking by each athlete. (the table can contain multiple bookings each to the same or different athletes (athlete_id) Once I have this information (booking_date and athlete_id) I then want to be able to automatically update the "Lastest ASP Session Field" in the Athlete Model. This is what I have tried so far. I can cycle through the bookings in the ASPBookings table and retieve and update the "Latest ASP Session Field" using the booking_date and athlete_id, but I cannot do this for multiple different athletes that are within the table. Currently the view just identifies the latest booking and the assigned athlete_id and then updates the field. Thanks in advance for any help. Below is the code.

I am trying to implement Django pagination on my page, and I don't want to show more than 5 pages at the same time. what I expect is, that when I click >> the next 5 pages are loaded so the user can click on it. But I don't know how I can do it so that when I click, the next 5 pages are displayed. For example, if the user clicks »: « 1 2 3 4 5 » Expected result: « 6 7 8 9 10 » Current result: « 1 2 3 4 5 » My code: index.html: {% for form in forms %} {% if forms.has_other_pages %} <ul class="nav nav-pills" id="evidence-formset-tab" role="tablist"> {% if forms.has_previous %} <li><a class="nav-link active" id="evidence-form-{{ forms.previous_page_number }}-tab" data-toggle="pill" href="#evidence-form-{{ forms.previous_page_number }}" role="tab" aria-controls="{{ aria_controls }}" aria-selected="true">&laquo;</a></li> {% else %} <li class="disabled"><span>&laquo;</span></li> {% endif %} {% for i in forms.paginator.page_range %} <li class="nav-item"> {% if forms.number == i %} <a class="nav-link active" id="evidence-form-{{ i }}-tab" data-toggle="pill" href="#evidence-form-{{ i }}" role="tab" aria-controls="{{ aria_controls }}" aria-selected="true">{{ i }}</a> {% elif i > forms.number|add:'-5' and i < forms.number|add:'5' %} <a class="nav-link" id="evidence-form-{{ i }}-tab" data-toggle="pill" href="#evidence-form-{{ i }}" role="tab" aria-controls="{{ aria_controls }}" aria-selected="false">{{ i }}</a> … -
Django Forum App, comments don't update on user-side, but can be seen through admin
For reference, here are my models in my Forum app: class Forum(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=100) description = models.TextField() created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title def get_absolute_url(self): return reverse('forum-detail', kwargs={'pk': self.pk}) class Comment(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) forum = models.ForeignKey(Forum, on_delete=models.CASCADE) description = models.TextField() created_at = models.DateTimeField(auto_now_add=True) To display the forum posts, I have a CBV 'ForumListView': class ForumListView(ListView): model = Forum template_name = 'forum/forum.html' context_object_name = 'forum_posts' ordering = ['-created_at'] From this list, the user can click on any forum and it will lead them to 'forum-detail' with the CBV 'ForumDetailView': class ForumDetailView(DetailView): model = Forum extra_context = { 'comments': Comment.objects.all().order_by('-created_at')} Here is where I passed in the comments from my Comment model to be shown alongside the post. I think this is the reason why the comments don't update, but I'm not too sure how to fix this. In the template for forum_detail.html, this is how I display all the comments made: {% for comment in comments %} {% if comment.forum == forum %} <div class="content-section"> <p>{{ comment.description }}</p> <small>{{ comment.user.username }}, on {{ comment.created_at|date:"F d, Y" }}</small> </div> {% endif %} {% endfor %} Note that the new comment made will be shown … -

In DJANGO, Is there a way to transfer the existing users in django.contrib.auth to SAML or OpenID?
I have used django-oidc-provider, but all it does is create a new user. For a large pre-existing user datatbase, it is inconvenient to create new accounts for all users. I want to do this because I cannot integrate AWS services into my django website without an industry standard for federated authentication.
