I have a model Pull_Requests in my database that's containing data and I want to display this data into an HTML table on my homepage. So I created the view, urls and home files as they are below but I'm getting nothing when I run the app. As I am new in this area, I'm not able to detect what could be the issue. Thanks in advance for your help.

from django.shortcuts import render

from django.views import View



class home(ListView):

    template_name = 'home.html'  



    def get_queryset(self, request):

        pull_requestsList = Pull_Requests.objects.all()

        pullRequest_dict = {'pull_requests': pull_requestsList}

        return render(request, self.template_name, pullRequest_dict)



    from django.urls import path from. import views

        urlpatterns = [

                path('', views.home, name='home'),

            ]



    % extends "base.html" %}

    {% load static %}



     {% block body %}

           <div class="container">

                {% if pullrequests %}

                    {% for field in pullrequests %}

                        <table>

                            <tr>

                                <th>{{ field.pr_project  }}</th>

                                <th>{{ field.pr_id }} </th>

                                <th>{{ field.nd_comments }} </th>

                                <th>{{ field.nb_added_lines_code }}</th>

                                <th>{{ field.nb_deleted_lines_code }}</th>

                                <th>{{ field.nb_commits }}</th>

                                <th>{{ field.nb_changed_fies }}</th>

                                <th>{{ field.Closed_status }}</th>

                                <th>{{ field.reputation }}</th>

                                <th>{{ field.Label }}</th>

                            </tr>

                        </table>

                    {% endfor %}

                {% else %}

                    <strong> There is no pull request in the database. </strong>

                {% endif %}

            </div>

    {% endblock %}

You have multiple issues.

The main problem is that get_queryset is supposed to return a queryset, not render a template. Because you do not return a queryset, and don't set the model attribute on the view, Django has no way of knowing what type of objects you're intending to list and therefore doesn't create a pullrequests object in the template context.

That method isn't doing anything useful anyway; you should probably just remove it, and define the attribute instead. So your view is literally just:

class home(ListView):

    template_name = 'home.html'  

    model = Pull_Requests

But note also that the name Django creates will be pull_requests_list, so you should use that in your template. (Also also, you don't need the if block; the for loop has an empty clause.) So:

{% block body %}

       <div class="container">

            {% for field in pull_requests_list %}

                <table>

                    <tr>

                        <th>{{ field.pr_project  }}</th>

                        <th>{{ field.pr_id }} </th>

                        <th>{{ field.nd_comments }} </th>

                        <th>{{ field.nb_added_lines_code }}</th>

                        <th>{{ field.nb_deleted_lines_code }}</th>

                        <th>{{ field.nb_commits }}</th>

                        <th>{{ field.nb_changed_fies }}</th>

                        <th>{{ field.Closed_status }}</th>

                        <th>{{ field.reputation }}</th>

                        <th>{{ field.Label }}</th>

                    </tr>

                </table>

            {% empty %}

                <strong> There is no pull request in the database. </strong>

            {% endfor %}

        </div>

{% endblock %}
