I'm learning to make some chat website, and i cannot quite get how to use urls correctly. The problem is that when I get to "http://127.0.0.1:8000/chat", links into the header became like "http://127.0.0.1:8000/chat/main" instead of "http://127.0.0.1:8000/main"
project urls:
from django.contrib import admin
from django.urls import path
from django.urls import include, path
from chat import views as chat_views
from mainapp import views as mainapp_views
urlpatterns = [
path('admin/', admin.site.urls),
path('', mainapp_views.index),
path('chat/', include('chat.urls')),
]
chat app urls:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('<str:room_name>/', views.room, name='room'),
]
chat app views:
from django.shortcuts import render
def index(request):
return render(request, 'chat/chatindex.html')
def room(request, room_name):
return render(request, 'chat/room.html', {
'room_name': room_name
})
index.html
<!DOCTYPE html>
{% load static %}
<html>
<head>
<meta charset="utf-8"/>
<link rel="stylesheet" href="{% static 'css/bootstrap.css' %}"/>
<title>{% block title %}{% endblock title %}</title>
</head>
<body>
<header>
<div class="navbar navbar-dark bg-dark shadow-sm">
<a href="" class="navbar-brand d-flex align-items-center">Главная</a>
<a href="searching" class="navbar-brand d-flex align-items-center">Поиск собеседников</a>
<a href="contacts" class="navbar-brand d-flex align-items-center">Контакты</a>
<a href="faq" class="navbar-brand d-flex align-items-center">FAQ</a>
<a href="login" class="navbar-brand d-flex align-items-center">Регистрация/Вход</a>
</div>
</div>
</header>
<main>
<div>{% block content%}{% endblock content %}</div>
</main>
<footer class="footer mt-auto py-3 bg-light">
<div class="container">
<span class="text-muted">Давай общаться!</span>
</div>
</footer>
</body>
</html>
chatindex.html
{% extends "index.html" %}
{% block title %}Контакты{% endblock title %}
{% block header %}{% endblock header %}
{% block content %}
В какую комнату хотите зайти?
<br>
<input id="room-name-input" type="text" size="100">
<br>
<input id="room-name-submit" type="button" value="Enter">
<script>
document.querySelector('#room-name-input').focus();
document.querySelector('#room-name-input').onkeyup = function(e) {
if (e.keyCode === 13) { // enter, return
document.querySelector('#room-name-submit').click();
}
};
document.querySelector('#room-name-submit').onclick = function(e) {
var roomName = document.querySelector('#room-name-input').value;
window.location.pathname = '/chat/' + roomName + '/';
};
</script>
{% endblock content%}
I'm pretty sure that the problem is about " path('<str:room_name>/', views.room, name='room')
", but i can't understand how to fix it and save opportunity to enter rooms with chat-page. Thanks a lot!
Very likely you make relative paths. Indeed, if you visit a page like some.domain.com/foo
, and the link is <a href="bar">link</a>
, then it will visit some.domain.com/foo/bar
, since that is a relative path: relative to the current path.
You can solve this by specifying an absolute path, which has a leading slash, so:
<!-- ↓ leading slash -->
<a href="/faq" class="navbar-brand d-flex align-items-center">FAQ</a>
But it is better not to generate URLs manually. If you later for example change the URL paths, you will need to alter all URLs. You can give your views a name, like:
path('faq', views.faq)
and in the template work with the {% url … %}
template tag [Django-doc] :
<!-- ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓ url template tag -->
<a href="" class="navbar-brand d-flex align-items-center">FAQ</a>
Django will then look for a view with the given name, and automatically generate the corresponding URL.
