Django Form Neither Shows Up nor Is It Integrated in The HTML
I'm trying to write a django form that works as a search bar, i've been following the tutorial i'm watching to the T, but for some reason when i run the code the form isn't there, and there's no trace of it in the HTML when i inspect it, it's as if i wrote nothing at all. below is the code i wrote in views.py, layout.html and the path in urls.py . It should be noted that this is the first time i work with django and so far it's been a bit confusing so please do check the code out and point out any and all bug(s). Thank You. Views.py from django import forms from django.shortcuts import render class searchForm(forms.Form): query = forms.CharField() def search(request): return render(request, "encyclopedia/entry.html", { "form": searchForm() }) layout.html <form action="{% url 'wiki:search' %}" method="post"> {{ form }} </form> urls.py from django.urls import path from . import views app_name = "wiki" urlpatterns = [ path("", views.index, name="index"), path("<str:title>", views.title, name="title"), path("<str:query>", views.search, name="search") ] -
How to group_by an annotated field for django querysets?
Hers is my model like this: class Article(models.Model): title = models.CharField(max_length=50, blank=True) author = models.CharField(max_length=50, blank=True) created_at = models.DateTimeField(auto_now_add=True) I want to return a queryset which is group_by created_at month, I annotated a created_month field for the queryset: queryset = Article.objects.annotate(created_month=TruncMonth('created_at')) but when I tried to group by created_at by adding .values('created_at'), like this: queryset = Article.objects.annotate(created_month=TruncMonth('created_at')).values('created_month').order_by('-created_month') The queryset returns only created_month field. What shall I do to get whole Article queryset group_by created_month like this: [ { 'created_month': '2021-07', 'articles': [ {'title': 'Article 1', 'author': ...} ] }, { 'created_month': '2021-06', 'articles': [ {'title': 'Article 2', 'author': ...}, {'title': 'Article 3', 'author': ...} ] } ] -

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. I was thinking there should be a way to explicitly call a specific slug and not render both buttons right next to each other -

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. ASPBookings Model. class ASPBookings(models.Model): asp_booking_ref = models.CharField(max_length=10, default=1) program_type = models.CharField(max_length=120, default='asp') booking_date = models.DateField() booking_time = models.CharField(max_length=10, choices=booking_times) duration = models.CharField(max_length=10, choices=durations, default='0.5') street = models.CharField(max_length=120) suburb = models.CharField(max_length=120) region = … -

How to limit the pages to display using Django pagination module
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 DJANGO, Is there a way to transfer the existing users in django.contrib.auth to SAML or OpenID?

Using Swup with Django
My Issue: I am trying to use Swup Library with Django's templating engine and everything worked well; except for the fetching of new content. The animations worked perfectly; I could see my contents getting faded out. The addresses in which the get requests are fetching worked perfectly as well; I could see the HTTP response code of 200 being returned in my console. However, the main content, after being faded out, were not being replaced. An example of Django Renderings: Base URL: http://127.0.0.1:8000 <!-- What is written in my code --> <a href="{% url 'home_view' %}" > <!-- What Django renders in the browser --> <a href="/" > in my urls.py: urlpatterns = [ path('', views.homeView, name='home_view'), ] A worthy note: Using dev tools, when hovering over the href rendered, it shows http://127.0.0.1:8000/ Another strange thing I encountered when trying to debug was that my html element has the following attributes added to it but it stay there even after the animation ends. <html lang="en" class="swup-enabled is-changing is-leaving is-animating to-homepage"> Swup config or any additional relevant code used: let options = { LINK_SELECTOR: 'a', debugMode: true, }; const swup = new Swup(options); The Scripts loaded perfectly; I was able to … -
Adding Additional Data to a Serialize Response in Django

integrating ebay authentication in django application
I am building a django application in which user will be able to sign up or sign in only via their EBay account, no email/username or password required. I couldn't find any authentication library for EBay though there are many for google, facebook, twitter etc. So I got the EBay part working. EBay basically returns (on consent of user) Email and a IEFS token which is unique to that user and wont change. I want to use those two fields only to create a authenticate user across whole application. I don't want username, emails, firstname, lastname or password that ships with django User model. The documentation is quite big and I am confused where to start, any proper suggestion will be big help. Thank you. -

I need to translate, or change "Please fill out this field" error message in UserCreationForm on Django

I have also tried on the forms.py changing the error_messages, but no luck, here is the code for the forms.py file (I have added 'required' everywhere just to see if the message slightly changes, no luck either, also I used 'required' and 'blank' neither worked): class CreateUserForm(UserCreationForm): first_name = forms.CharField(error_messages = {'required':"Ingrese su primer nombre"}, max_length=30,widget=forms.TextInput(attrs={'placeholder': 'Ingrese su nombre', 'class': "form-control"})) last_name = forms.CharField(error_messages = {'required':"Ingrese su segundo nombre"},max_length=30,widget=forms.TextInput(attrs={'placeholder': 'Ingrese su apellido', 'class': "form-control"})) password1 = forms.CharField( label="Password", error_messages = {'required':"Ingrese la … -
Django Get All Cookies With Name That Includes A Substring
I am making this simple random post system, and a problem I've been having is to recommend posts a user has not seen before.

This is my code: import random def random_post(request): objects_to_exclude = [1, 2, 8] # Using the cookies with substring "viewed" I want to insert into this list posts = Post.objects.all().exclude(pk__in=objects_to_exclude) post = random.choice(posts) return render(request, 'blog/post_detail.html', {'object': post, 'post': post, 'id': post.id, 'pk': post.id, 'random': 'True'}) Basically I want to find all the cookies with substring viewed, get the number after it, and then insert it into the list called objects_to_exclude.

Given these models: class Group(models.Model): name = models.CharField() class Member(models.Model): name = models.CharField() group = models.ForeigKey(Group, blank=True, null=True) And this factory: class MemberFactory(factory.django.DjangoModelFactory): class Meta: model = Member name = factory.Sequence("Member {}".format) group = factory.Subfactory(GroupFactory) I would like the option of only creating a group if explicitly requested, but without losing all other features. In other words these should all work: MemberFactory() # Expect group=None MemberFactory(group=True) # Expect group=GroupFactory() MemberFactory(group__name="ABC") MemberFactory(group=Group.objects.get(...)) -
