                <h2>Wiki</h2>
                <form action = "{% url 'search' %}" method="GET">

                {% endblock %}
            </div>
        </div>

    </body>
</html>

my views.py:

def search(request):   
result = set()
entries = util.list_entries()
if request.method == 'GET':
    query = request.GET.get('q')    
    if query == '': #If it's nothing
        query = 'NONE'    
    if query in entries:
        return redirect(f'wiki/{query}')
    else:
        results = [entry for entry in entries if query.lower() in entry.lower()]
        return render(request, "encyclopedia/index.html", {
            "entries": results
            })
               
return render(request, 'encyclopedia/search.html', {'results':result})

my urls:

    from django.urls import path
from django.conf import settings
from django.conf.urls.static import static
from . import views

app_name = 'encyclopedia'

urlpatterns = [
    path("", views.index, name="index"),
    path('newpage/', views.new_page, name = 'newpage'),
    path('wiki/<str:title>', views.entry, name = 'entries'),
    path('wiki/<str:title>/edit',views.edit, name = 'edit'),
    path('search', views.search, name = 'search'),
    path('wiki/<str:entry>', views.random_page, name = 'random'),
]

urlpatterns  = static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

How do i make it work? it worked before but now it just stopped working. The name in the urls matches with the name of a bar What i have to know about url method? I also tried to write {% url 'random'%} for a random page but it seems not working at all When i added this to a random search url stopped working and i do not know why

Versions: Django 4.1.4, Python 3.10.5

CodePudding user response:

You have declared app_name in your urls.py file that makes it compulsory to add app_name before calling a url in django. Call your urls like this...

href={% url 'app_name:url_name' %}

So your code will be like this...

{% load static %}
<!DOCTYPE html>
<html lang="en">
    <head>
        <title>{% block title %}{% endblock %}</title>

        <link href="{% static 'encyclopedia/styles.css' %}" rel="stylesheet">
    </head>
    <body>
        <div >
            <div >
                <h2>Wiki</h2>
                <form action = "{% url 'encyclopedia:search' %}" method="GET">
                    <input  type="text" name="q" placeholder="Search Encyclopedia">
