I'm writing a Django app to manage sales leads. From the template that lists a page of leads, I want to give the user the ability to search all leads using first name and last name as the search criteria. When I type in a last name and press enter, the page flickers but remains on the same page rather than the template I created to list the search results.

My views, urls, and templates are below. What have I missed?

views.py

class LeadsListView(ListView):
    model = Lead
    template_name = 'leads/list.html'
    context_object_name = 'leads_list'
    paginate_by = 10

    def get_queryset(self):
        return Lead.objects.order_by('id')

class LeadsSearchResultsView(ListView):
    model = Lead
    context_object_name = 'search_results'
    template_name = 'leads/search_results.html'
    paginate_by = 10

    def get_queryset(self):
        query = self.request.GET.get('q')

        return Lead.objects.filter(
            Q(last__icontains=query) | Q(first__icontains=query)
        )

urls.py

from django.urls import path
from .views import LeadsListView, LeadsDetailView, LeadsCreateView
from .views import LeadsSearchResultsView

app_name = 'lead'

urlpatterns = [
    path('', LeadsListView.as_view(), name='list'),
    path('<int:pk>/', LeadsDetailView.as_view(), name='detail'),
    path('', LeadsCreateView.as_view(), name='create'),
    path('', LeadsSearchResultsView.as_view(), name='search_results'),
]

The template that (successfully!) lists the leads, list.html:

{% extends 'base.html' %}

{% block content %}
<nav aria-label="Page navigation example">
    <ul >
        {% if page_obj.has_previous %}
        <li >
            <a  href="?page={{ page_obj.previous_page_number }}" aria-label="Previous">
                <span aria-hidden="true">&laquo;</span>
                <span >Previous</span>
            </a>
        </li>
        {% endif %}
        {% if page_obj.has_next %}
        <li >
            <a  href="?page={{ page_obj.next_page_number }}" aria-label="Next">
                <span aria-hidden="true">&raquo;</span>
                <span >Next</span>
            </a>
        </li>
        {% endif %}
        <form action="{% url 'lead:search_results' %}" method="get">
            <input type="search" name="q" value="{{ request.GET.q }}" placeholder="Search by last name"
                >
        </form>
    </ul>
</nav>

<table >
    <thead>
        <tr>
            <th scope="col">Lead No.</th>
            <th scope="col">First</th>
            <th scope="col">Last</th>
            <th scope="col">Phone</th>
            <th scope="col">Email</th>
            <th scope="col">Zip Code</th>
        </tr>
    </thead>
    <tbody>
        {% for lead in page_obj %}
        <tr>
            <td><a href="{% url 'lead:detail' lead.pk %}">{{ lead.pk }}</a></td>
            <td>{{ lead.first }}</td>
            <td>{{ lead.last }}</td>
            <td>{{ lead.mobile }}</td>
            <td>{{ lead.email }}</td>
            <td>{{ lead.zipcode }}</td>
        </tr>
        {% endfor %}
    </tbody>
</table>
{% endblock content %}

And finally, the template that should list the results of the search, but doesn't, search_results.html:

{% extends 'base.html' %}

{% block content %}
<nav aria-label="Page navigation example">
    <ul >
        {% if page_obj.has_previous %}
        <li >
            <a  href="?page={{ page_obj.previous_page_number }}" aria-label="Previous">
                <span aria-hidden="true">&laquo;</span>
                <span >Previous</span>
            </a>
        </li>
        {% endif %}
        {% if page_obj.has_next %}
        <li >
            <a  href="?page={{ page_obj.next_page_number }}" aria-label="Next">
                <span aria-hidden="true">&raquo;</span>
                <span >Next</span>
            </a>
        </li>
        {% endif %}
        <form action="{% url 'lead:search_results' %}" method="get">
            <input type="search" name="q" value="{{ request.GET.q }}" placeholder="Search by last name"
                >
        </form>
    </ul>
</nav>

<table >
    <thead>
        <tr>
            <th scope="col">Lead No.</th>
            <th scope="col">First</th>
            <th scope="col">Last</th>
            <th scope="col">Phone</th>
            <th scope="col">Email</th>
            <th scope="col">Zip Code</th>
        </tr>
    </thead>
    <tbody>
        {% for lead in page_obj %}
        <tr>
            <td><a href="{% url 'lead:detail' lead.pk %}">{{ lead.pk }}</a></td>
            <td>{{ lead.first }}</td>
            <td>{{ lead.last }}</td>
            <td>{{ lead.mobile }}</td>
            <td>{{ lead.email }}</td>
            <td>{{ lead.zipcode }}</td>
        </tr>
        {% endfor %}
    </tbody>
</table>
{% endblock content %}

CodePudding user response：

Below is your url.py file

urlpatterns = [
    path('', LeadsListView.as_view(), name='list'),
    path('<int:pk>/', LeadsDetailView.as_view(), name='detail'),
    path('', LeadsCreateView.as_view(), name='create'),
    path('', LeadsSearchResultsView.as_view(), name='search_results'),
]

Here, you are calling 3 different views class with the same url '' which is wrong.

You can correct the same and proceed further.
