Pagination in Django ListView when using get_context_data

I am currently facing this problem with Django ListView. Basically, I need to filter some questions per topic and I would like to paginate the results.
My code is working perfectly about the queryset part (the results are showed correctly) but I am facing a problem with pagination.
Let's say I have so far 8 items in my query, if I choose to paginate_by = 10, it shows me just one page. If, otherwise, I choose to paginate by, let's say, 3, it shows me 3 pages to choose in the template (which is correct) but it shows me ALL the results of the query in my page.
I post some code to be more clear
models.py:
class Tag(models.Model):
name = models.CharField(max_length=300, unique=True)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
def clean(self):
self.name = self.name.capitalize()
def __str__(self):
return self.name
class Question(models.Model):
post_owner = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=5000, default='')
body = tinymce_models.HTMLField()
tags = models.ManyToManyField(
Tag, related_name='tags')
viewers = models.ManyToManyField(
User, related_name='viewed_posts', blank=True)
views.py:
class TagQuestionsListView(ListView):
template_name = 'main/tag_questions.html'
paginate_by = 20
def get_queryset(self, **kwargs):
tag = Tag.objects.get(name=self.kwargs['name'])
questions = Question.objects.filter(tags=tag)
return questions
def get_contextdata(self, **kwargs):
context = super().get_context_data(**kwargs)
context['tag'] = Tag.objects.get(name=self.kwargs['name'])
context['questions'] = Question.objects.filter(
tags=context['tag'], is_deleted=False)
return context

With this I want my comment converter to answer.
You have to use page_obj instead questions in your template.
<--! ⬇️⬇️⬇️ -->
{% for question in page_obj %}
<div class="row">
<div class="col-2 ms-2">
<p>{{ question.count_all_the_votes }} Voti</p>
<p>{{ question.count_answers }} Risposte</p>
<p>{{ question.calculate_viewers }} Visualizzazioni</p>
</div>
<div class="col-9">
<h5>{{question.title}}</h5>
<div class="text">
{{ question.body|striptags }}
</div>
{% for tag in question.tags.all %}
<a class="btn btn-sm btn-outline-primary m-1" href="{% url 'main:tag_questions' name=tag.name %}">{{tag.name}}</a>
{% endfor %}
<div class="float-end">
<a style="display: inline;" href="">{{question.post_owner}}</a>
{% if question.is_edited == False %}
<span style="display:inline;">creata {{question.created_at | naturaltime}}</span>
{% else %}
<span style="display:inline;"> modificata {{question.edited_time | naturaltime}} da <a style="display: inline;" href="">{{question.edited_by.username}}</a></span>
{% endif %}
</div>
</div>
</div>
<hr>
{% endfor %}
So, if you define attribute paginate_by , than ListView(django docs) adds a paginator and page_obj to the context. To allow the users to navigate between pages, add links to the next and previous page, in your template.

How to use Django URL field?

I have an URL field in Django to which I am adding the URL of a photo, how can I render this image to the frontend of my website.
models.py file code for reference
class Place(models.Model):
place_photo = models.ImageField(upload_to='photos/%Y/%m/%d/')
place_photo_1 = models.ImageField(upload_to='photos/%Y/%m/%d/')
place_photo_2 = models.ImageField(upload_to='photos/%Y/%m/%d/')
place_photo_3 = models.ImageField(upload_to='photos/%Y/%m/%d/')
place_photo_4 = models.ImageField(upload_to='photos/%Y/%m/%d/')
field_name = models.URLField(max_length=500,default='add photo url')
def __str__(self):
return self.place_title
This is my template.html code

I am new to Django, so if I am doing any mistake then please help me out. It would be really appreciable

Django paginator issue

I am currently working on a django blog and I've coded a search bar where you type something and, if there's any post that contains what you've typed in the title, it should appear all the posts. This part is perfectly well-written. However, there's an error with the pagination. As you'll see in the views.py. The maximum num of posts per page is 3. However, you can see there's four. However, the paginator detects there should be another page for the fourth posts. Here's an image that shows that.
Here's the views.py:
class ElementSearchView(View):
elements_list = Element.objects.all()
def get(self, request, *args, **kwargs):
paginator = Paginator(self.elements_list, 3)
page_request_var = 'page'
page = request.GET.get(page_request_var)
try:
paginated_queryset = paginator.page(page)
except PageNotAnInteger:
paginated_queryset = paginator.page(1)
except EmptyPage:
paginated_queryset = paginator.page(paginator.num_pages)
queryset = Element.objects.all()
query = request.GET.get('q')
if query:
queryset = queryset.filter(
Q(title__icontains=query)
).distinct()
context = {
'query': queryset,
'queryset': paginated_queryset,
'page_request_var': page_request_var,
}
return render(request, 'periodic/search_results_table.html', context)
And here's the html template: The pagination is at the end of the template.
{% load static %}
<html>
{% include 'periodic/head_search.html' %}
<body>
{% include 'periodic/header.html' %}
<br>
<br>
<div class="container">
<div class="row">
<!-- Latest Posts -->
<main class="posts-listing col-lg-8">
<div class="container">
<div class="row">
<!-- post -->
{% for element in query %}
<div class="post col-xl-6 wrap-login100">
<div class="post-thumbnail"><img src="{{ element.thumbnail.url }}" alt="..." class="img-fluid"></div>
<div class="post-details">
<a href="{{ element.get_absolute_url }}">
<h3 class="h4">{{ element.title }}</h3></a>
</div>
</div>
{% endfor %}
</div>
<!-- Pagination -->
<nav aria-label="Page navigation example">
<ul class="pagination pagination-template d-flex justify-content-center">
{% if queryset.has_previous %}
<li class="page-item"> <i class="fa fa-angle-left"></i></li>
{% endif %}
<li class="page-item">{{ queryset.number }}</li>
{% if queryset.has_next %}
<li class="page-item"> <i class="fa fa-angle-right"></i></li>
{% endif %}
</ul>
</nav>
{% if is_paginated %}
<nav aria-label="Page navigation example">
<ul class="pagination pagination-template d-flex justify-content-center">
{% if page_obj.has_previous %}
<li class="page-item"> <i class="fa fa-angle-left"></i></li>
{% endif %}
<li class="page-item">{{ page_obj.number }}</li>
{% if page_obj.has_next %}
<li class="page-item"> <i class="fa fa-angle-right"></i></li>
{% endif %}
</ul>
</nav>
{% endif %}
</div>
</main>
</body>
{% include 'periodic/scripts_search.html' %}
</html>

As the user #ikilnac mentioned,
you are looping over the original queryset and not the paged one in your template
That simply means that in your loop, you do this
{% for element in query %}
<div class="post col-xl-6 wrap-login100">
<div class="post-thumbnail"><img src="{{ element.thumbnail.url }}" alt="..." class="img-fluid"></div>
<div class="post-details">
<a href="{{ element.get_absolute_url }}">
<h3 class="h4">{{ element.title }}</h3></a>
</div>
</div>
{% endfor %}
And then after that, you are using the tag in the form of {% if queryset.has_previous %} with the original queryset rather than the paged one in the template (the query).
There's a good example of it here - Paginate with Django

Django: Using a loop to output images and text from the db

I'm learning programming and following a tutorial using django 3, the same I'm using.
The text and images are not displaying on the frontend on one particular html file.
1.-In settings.py I have this:
MEDIA_ROOT= os.path.join(BASE_DIR,"media")
MEDIA_URL= "/media/"
2.-In models.py:
class Property(models.Model):
title = models.CharField(max_length=200)
main_photo = models.ImageField(upload_to='photos/%Y/%m/%d/')
3.-In admin.py:
from django.contrib import admin
from .models import Property
class PropertyAdmin(admin.ModelAdmin):
list_display = ('id', 'title', 'is_published')
list_display_links = ('id', 'title')
search_fields = ('title', 'town')
list_editable = ('is_published',)
list_per_page = 30
admin.site.register(Property, PropertyAdmin)
Then I migrated to the DB, I created a properties.html and the loop {{ property.main_photo.url }} or {{ property.title }} is working and getting images and texts on this properties file:
{% extends 'base.html' %}
{% load humanize %}
{% block content %}
<section id="showcase-inner" class="py-5 text-white">
<div class="container">
<div class="row text-center">
<div class="col-md-12">
<h1 class="display-4">Browse Our Properties</h1>
<p class="lead">Lorem ipsum dolor sit, amet consectetur adipisicing elit. Sunt, pariatur!</p>
</div>
</div>
</div>
</section>
<!-- Listings -->
<section id="listings" class="py-4">
<div class="container">
<div class="row">
{% if properties %}
{% for property in properties %}
<div class="col-md-6 col-lg-4 mb-4">
<div class="card listing-preview">
<img class="card-img-top" src="{{ property.main_photo.url }}" alt="">
<div class="card-img-overlay">
<h2>
<span class="badge badge-secondary text-white">From {{ property.price_per_week | intcomma }}€ per week</span>
</h2>
</div>
<div class="card-body">
<div class="listing-heading text-center">
<h4 class="text-primary">{{ property.title }}</h4>
<p>
<i class="fas fa-map-marker text-secondary"></i> {{ property.town }}</p>
</div>
<hr>
<div class="row py-2 text-secondary">
<div class="col-6">
<i class="fas fa-check"></i> {{ property.swimming_pool }}</div>
<div class="col-6">
<i class="fas fa-wifi"></i> {{ property.free_wifi }}</div>
</div>
<div class="row py-2 text-secondary">
<div class="col-6">
<i class="fas fa-bed"></i> Bedrooms: {{ property.bedrooms }}</div>
<div class="col-6">
<i class="fas fa-bath"></i> Bathrooms: {{ property.bathrooms }}</div>
</div>

</div>
</div>
</div>
{% endfor %}
{% else %}
<div class="col-md-12">
<p>No Properties available</p>
</div>
{% endif %}
</div>
<div class="row">
<div class="col-md-12">
{% if properties.has_other_pages %}
<ul class="pagination">
{% if properties.has_previous %}
<li class="page-item">
<a href="?page={{properties.previous_page_number}}" class="page-link">«
</a>
</li>
{% else %}
<li class="page-item-disabled">
<a class="page-link">«</a>
</li>
{% endif %}
{% for i in properties.paginator.page_range %}
{% if properties.number == i %}
<li class="page-item active">
<a class="page-link">{{i}}</a>
</li>
{% else %}
<li class="page-item">
{{i}}
</li>
{% endif %}
{% endfor %}
</ul>
{% endif %}
</div>
</div>
</div>
</section>
{% endblock %}
The next step is to create a property.html file and also use loop, but everything that uses the loop doble curly braces are not displaying:
{% extends 'base.html' %}
{% load humanize %}
{% block content %}
<section id="showcase-inner" class="py-5 text-white">
<div class="container">
<div class="row text-center">
<div class="col-md-12">
<h1 class="display-4">{{ property.title }}</h1>
<p class="lead">
<i class="fas fa-map-marker"></i> {{ property.town }}</p>
</div>
</div>
</div>
</section>
{% endblock %}
I checked multiple times and my code is exactly like on the tutorial but my frontend is not displaying.
Views.py:
from django.shortcuts import get_object_or_404, render
from django.core.paginator import EmptyPage, PageNotAnInteger, Paginator
from .models import Property
def index(request):
properties = Property.objects.get_queryset().order_by('id').filter(is_published=True)
paginator = Paginator(properties, 30)
page = request.GET.get('page')
paged_properties = paginator.get_page(page)
context = {
'properties': paged_properties
}
return render(request, 'properties/properties.html', context)
def property(request, property_id):
property = get_object_or_404(Property, pk=property_id)
context = {
'property': property
}
return render(request, 'properties/property.html')
def search(request):
return render(request, 'properties/search.html')

You are not passing the context to properties/property.html inside def property(..., ...)
Change:
return render(request, 'properties/property.html')
To:
return render(request, 'properties/property.html', context)

Every time I request a blog post on my website, I receive a server error 500. I have been trying to debug it for the past 3 days, and I have not been able to figure out what is going on. Here is the views.py for the blog detail:

Post is the model that contains the blog post. I have not been able to find the reasong why when I request a blog page it throws an error. Does anyone know why?

I figured out what happened. After #Tnerual's comment, I checked my urls.py and realized request_post wasn't defined.
