Django. Url cant find view

I need help with {% url (url to template) %} when i try to open another view i see a NoRewerseMatch error.
here is my html file:
{% load static %}
<head>
<link href='{% static "navbar_style.css" %}' rel="stylesheet", type="text/css">
</head>
<header>
<nav class="headlist">

<ul>

my app(pages)/urls.py
from django.contrib import admin
from django.urls import path
from . import views
app_name = 'pages'
urlpatterns = [
path('', views.home_view, name='home_view'),
path('index/', views.index_view, name='index_view'),
]
views.py
import...
# Create your views here.
def home_view(request):
listoftexts = Text.objects.order_by('-pub_date')
context = {
'listoftexts': listoftexts
}
return render(request, 'pages/home.html', context)
def index_view(request):
listoftexts = Text.objects.order_by('-pub_date')
context = {
'listoftexts': listoftexts
}
return render(request, 'pages/index.html', context)

You can do it like this.

The name of the view is home_view:
path('', views.home_view, name='home_view'),
so you can use the {% url … %} template tag [Django-doc] with:
<a href="{% url 'home_view' %}">
If you use an app_name in the urls.py, you also need to prefix this in the url:
<a href="{% url 'pages:home_view' %}">

The url_name should be home_view not home. The name parameter in the path function is what you use to refernce the view.

Implementing Search Form with Django

Hello Stackoverflow community,
I am having trouble with my form not rendering in Django.
Here's my attempt to render an empty form in views.py.
class SearchSite(forms.Form):
query = forms.CharField(label="New Item",
help_text="Search for any article located on the site.")
def search(request):
form = SearchSite()
context = {
"form": form,
"query_matches": query_matches
}
response = render(request, "encyclopedia/layout.html", context)
return response
Here's what my urls.py file looks like:
urlpatterns = [
path("", views.index, name="index"),
path("wiki/<str:page_title>", views.page, name="wiki"),
path("wiki/", views.search, name="site_search")
]
My layout.html file:
{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<title>{% block title %}{% 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 'encyclopedia/styles.css' %}" rel="stylesheet">
</head>
<body>
<div class="row">
<div class="sidebar col-lg-2 col-md-3">
<h2>Wiki</h2>
<form action="{% url 'site_search' %}" method="get">
{% csrf_token %}
There should be something here
{{ form }}
<input type="submit">
</form>
<div>
Home
</div>
<div>
Create New Page
</div>
<div>
Random Page
</div>
{% block nav %}
{% endblock %}
</div>
<div class="main col-lg-10 col-md-9">
{% block body %}
{% endblock %}
</div>
</div>
</body>
</html>
I have noticed two particular problems in above screenshot. Firstly, my form does not render when inside my index.html webpage, which extends layout.html. Secondly, when I click the submit button, I get routed to a webpage that has my CSRF token in the url ... and then finally renders my form.
How can I fix this? Thanks everyone.

I have noticed two particular problems in above screenshot. Firstly,
my form does not render when inside my index.html webpage, which
extends layout.html.
Yes. You aren't passing form to index.html. Pass that in the view which renders the homepage. Even if it extends from layout.html, you need to pass it in the context for it to work.
def index(request):
# Your code.
return render(request, 'index.html', {'form': SearchSite()})
Secondly, when I click the submit button, I get routed to a webpage
that has my CSRF token in the url ... and then finally renders my
form.
That's because, in index.html, there is a blank form with a csrf_token, with an action set to /wiki, which calls search when the submit button is pressed. And search gives you layout.html, with the form, and as the form method is GET, it shows it in the url. I suggest changing it to POST if there is confidential data (and even otherwise. Why is there a csrf_token if it is not a POST request? Not needed. If you really want a GET request, then remove the csrf_token).

Here's my solution to the problem I had earlier for any future people visiting the post.
I wrote a form called SearchSite and defined a view called search in my views.py.
class SearchSite(forms.Form):
query = forms.CharField(
help_text="Search for any article located on the site.")
def search(request):
form = SearchSite()
is_substring_of_queries = []
if request.method == "GET":
form = SearchSite(request.GET)
if form.is_valid():
for entry in util.list_entries():
existsIdenticalResult = form.cleaned_data["query"].casefold() == entry.casefold()
existsResult = form.cleaned_data["query"].casefold() in entry.casefold()
if existsIdenticalResult:
return HttpResponseRedirect(reverse("wiki",
kwargs={"page_title": entry}))
elif existsResult:
is_substring_of_queries.append(entry)
context = {
"form": SearchSite(),
"is_substring_of_queries": is_substring_of_queries
}
response = render(request, "encyclopedia/search.html", context)
return response
When my view.search is requested, it will send the response of either an empty form (if accessed by index.html or if there are no results with a message saying there are no results) , an empty form and all the queries that are substrings of the markdown entries or route the client to an exact entry if the query matched.
Here's the routing down in my urls.py so far:
urlpatterns = [
path("", views.index, name="index"),
path("wiki/<str:page_title>", views.page, name="wiki"),
path("search/", views.search, name="site_search")
]
In my layout.html, I have the following form:
<form action="{% url 'site_search' %}" method="get">
{{ form }}
<input type="submit">
</form>
as well as in my search.html the queries that are substrings of the markdown entries:
{% if is_substring_of_queries %}
<h1>Search Results</h1>
{% for query in is_substring_of_queries%}
<li> {{ query }} </li>
{% endfor %}
{% else %}
<h1>No Results! Try again.</h1>
{% endif %}
If there are any mistakes, please let me know.

select an random page with django

I'm trying to select a random page with Django but I don't know how to call the function.
I tried to call it with an URL but it didn't work.
views.py:
def random_page(request):
entries = util.list_entries() # list of wikis
selected_page = random.choice(entries)
return render(request, "encyclopedia/layout.html", {
"random_page": selected_page
})
urls.py:
from . import views
app_name = "encyclopedia"
urlpatterns = [
path("", views.index, name="index"),
path("wiki/<str:page_title>", views.wiki_page, name="wiki_page"),
path("create", views.add_entry, name="add_entry"),
path("search", views.search, name="search"),
path("wiki/edit/<str:page_title>", views.edit_page, name="edit_page")
]
layout.html:
{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<title>{% block title %}{% 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 'encyclopedia/styles.css' %}" rel="stylesheet">
</head>
<body>
<h2>Wiki</h2>
<form action="{% url 'encyclopedia:search' %}" method="POST">
{% csrf_token %}
<input class="search" type="text" name="q" placeholder="Search Encyclopedia">
</form>
Home
Create New Page
<a href=wiki/{{ random_page }}>Random Page</a>
{% block body %}
{% endblock %}
</body>
</html>

Why not redirect to a given page. You thus redirect the browser to a page with a given page title. The advantage is that you make it simpler and only have to write the redirect logic once.
from django.shortcuts import redirect
def random_page(request):
entries = util.list_entries() # list of wikis
selected_page = random.choice(entries)
return redirect('encyclopedia:wiki_page', page_title=selected_page)
You then specify a path in your urls.py:
urlpatterns = [
path("", views.index, name="index"),
path("random/", views.random_page, name="index"),
path("wiki/<str:page_title>", views.wiki_page, name="wiki_page"),
path("create", views.add_entry, name="add_entry"),
path("search", views.search, name="search"),
path("wiki/edit/<str:page_title>", views.edit_page, name="edit_page")
]
If you then visit /random it will redirect to a random page.

I wrote the view in this way
def random_page(request):
entries = util.list_entries()
selected_page = random.choice(entries)
return HttpResponseRedirect(reverse('wiki', args=[selected_page]))

i did't understand where the proble is because when i rub or erase the
first url code that is url('', views.home,name='home'),
it will show the result page but it will not coonect when i push the submit buttonenter code here

Change your url of home to:
url(r'^$', views.home, name='home'),
otherwise all cases will be handled by home.
Or move your add url above to make django see it first. Sequence of urls matters in django.
url(r'^add/', views.add, name ='add'),
url('', views.home,name='home'),

perhaps the / is causing the issue
try this:
<form action="add/">
and the url is missing the beginning/end regex
url('^$', views.home,name='home'),
