How to customize SearchHeadline in django full text search?
I want to highlight search terms with SearchHeadline. My code is somethink like this: query = SearchQuery('cat') vector = SearchVector('caption') Post.objects.annotate( search=vector headline=SearchHeadline( 'caption', query ) ).filter(search=query) This code works well and for example the headline of the first result is: 'My <b>cat</b> breed is Persian. Persian cats are the most beautiful breed.' As you can see cat is highlighted but cats is not, and I want to highlight all of cat string in the caption, like this: 'My <b>cat</b> breed is Persian. Persian <b>cat</b>s are the most beautiful breed.' -

Should I create an app for every page? (Django)
I'm new to Django. I am currently trying to bring my static html/css website to Django (mainly for learning). My only doubt is: should I use a new app for every page I have? The doubt comes from the fact that the title which I'll give to the pages are different, hence making page_title variable requires me to write in views.py, but I can't (maybe I'm wrong) write multiple page_title variables inside the same app's views.py. Thanks for your time! -
Django Filter SearchForm by a Category
My Django application has a search function. To give the user a more accurate search result its also possible to filter by a category before sending the search request. To get the Category object the user can select from at a drop-down menu, I have a form like this: class CategorySearchForm(forms.ModelForm): class Meta: model = Post fields = ['category'] def __init__(self, *args, **kwargs): kwargs.setdefault('label_suffix', '') super(CategorySearchForm, self).__init__(*args, **kwargs) self.fields['category'].required = False self.fields['category'].empty_label = 'All Categories' Currently this is working but to me this is ugly as I reference my category objects by my Post model: category = models.ForeignKey(Category, verbose_name="Category", on_delete=models.CASCADE, null=True) Now my Question: How can I get all Category objects at my CategorySearchForm directly by the Category model instead of the Post model? This is how my Category Model looks like: class Category(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.CharField(verbose_name="Title", max_length=40, validators=[MinLengthValidator(5)]) description = models.TextField(verbose_name="Description", max_length=3000, validators=[MinLengthValidator(150)], blank=False) published_date = models.DateTimeField(auto_now_add=True, null=True) class Meta: verbose_name = "Category" verbose_name_plural = "Categories" ordering = ['title'] def __str__(self): return self.title def publish(self): self.published_date = timezone.now() self.save() -

Then, I want to add point 1 if user's answer is correct. I wonder can I modify this code "Profile.objects.values('user_test_point').update(user_test_point + 1)"?

How to filter and paginate in ListView Django
I have a problem when I want to paginate the filter that I create with django_filter, in my template it shows me the query set and filter but paginate does not work, I would like to know why this happens and if you could help me.

This is my views.py PD: i have all the necesary imports. @method_decorator(staff_member_required, name='dispatch') class EmployeeListView(ListView): model = Employee paginate_by = 4 def dispatch(self, request, *args, **kwargs): if not request.user.has_perm('employee.view_employee'): return redirect(reverse_lazy('home')) return super(EmployeeListView, self).dispatch(request, *args, **kwargs) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['filter'] = EmployeeFilter(self.request.GET, queryset = self.get_queryset()) return context filters.py import django_filters from .models import Employee, Accident class EmployeeFilter(django_filters.FilterSet): class Meta: model = Employee fields = { 'rutEmployee' : ['startswith'] } and employee_list.html {% extends 'core/base.html' %} {% load bootstrap %} {% load static %} {% block title %}EMPLEADOS{% endblock %} {% block content %} <main role="main"> <div class="row"> <div class="col-md-12 stretch-card"> <div class="card"> <div class="card-body"> <p class="card-title">Lista de Empleados</p> <div class="table-responsive"> <form method="GET"> {{ filter.form|bootstrap }} <button type="submit" class="btn btn-primary">Filtrar</button> </form> <hr> <table class="table table-bordered"> <thead> <tr> <th>Rut</th> <th>Nombre</th> <th>Apellido Paterno</th> <th>Detalle</th> </tr> </thead> <tbody> {% for employee in filter.qs|dictsort:"id" reversed %} … -
Backend interfering with load times - Django
I am working on a project where a backend function in my Django project pulls data and then runs a data analysis on it. The issue I am encountering is that while this is happening the frontend shows a 404 error until the analysis is complete. As this will be client-facing is there a way to fix this without rewriting the analysis in Javascript? -

Javascript runs in template html file but not extended html file in Django application
I am writing a website in Django and Vanilla JS I have 2 html pages, I want them both to share css but I want them to use different javascript. Both pages extend a layout.html. The layout.html looks begins like this {% load static %} <!DOCTYPE html> <html lang="en"> <head> <title>{% block title %}Social Network{% endblock %}</title> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous"> <link href="{% static 'network/styles.css' %}" rel="stylesheet"> </head> My index.html (which extends my layout.html) begins like this {% extends "network/layout.html" %} {% load static %} <script src="{% static 'network/messages.js' %}"></script> and my Javascript file looks like this: document.addEventListener('DOMContentLoaded', function() { console.log("page loaded!") document.addEventListener('click', event => { const element = event.target; console.log("Something was clicked") }) }); It simply prints out a line when the page is loaded and when something is clicked. However, when I go to index.html with the code like this, the javascript file is not loaded, nothing is printed out when the page is loaded or when anything is clicked. However, if I modify the layout.html page to be like this: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <title>{% block title %}Social Network{% endblock %}</title> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous"> <link href="{% static 'network/styles.css' %}" … -
