Using the URLconf defined in custom.urls, Django tried these URL patterns, in this order:
admin/ posts/ [name='posts_list'] <slug>The current path, posts/first, didn't match any of these.
this is models.py
from django.db import models
from django.conf import settings
Create your models here.
User = settings.AUTH_USER_MODEL
class Author(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
email = models.EmailField()
phone_num = models.IntegerField(("Phone number"))
def __str__(self):
return self.user.username
class Post(models.Model):
title = models.CharField(max_length=120)
description = models.TextField()
slug = models.SlugField()
image = models.ImageField()
author = models.OneToOneField(Author, on_delete=models.CASCADE)
def __str__(self):
return self.title
this is views.py
from django.shortcuts import render, get_object_or_404
from .models import Post
# Create your views here.
def posts_list(request):
all_posts = Post.objects.all()
return render(request,
"posts/posts_list.html",
context = {"all_posts": all_posts})
def posts_detail(request, slug):
unique_slug = get_object_or_404(Post, slug = slug)
return render(request, "posts/posts_detail.html", {"post": unique_slug})
this is the urls.py
from django.contrib import admin
from django.urls import path
from posts.views import posts_list, posts_detail
urlpatterns = [
path('admin/', admin.site.urls),
path("posts/", posts_list, name = "posts_list"),
path("<slug>", posts_detail), #, name = "unique_slug"
]
and this is those are the templates: posts_list.html
<!DOCTYPE html>
<html>
<head>
<title>
</title>
</head>
<body>
{{ all_posts }}
</body>
</html>
post_detail.html
<!DOCTYPE html>
<html>
<head>
<title>
</title>
</head>
<body>
{{ post }}
</body>
</html>

A slug never contains a slash. It looks like your url is prefixed with posts/. So you can alter your urls.py with:
from django.contrib import admin
from django.urls import path
from posts.views import posts_list, posts_detail
urlpatterns = [
path('admin/', admin.site.urls),
path('posts/', posts_list, name='posts_list'),
path('posts/<slug:slug>/', posts_detail, name='unique_slug'),
]It is probably better to add the type of the path converter, so <slug:slug>.
You might want to use django-autoslug [GitHub] to automatically construct a slug based on a certain field.

You have made two mistakes here first>>>
#you havent closed the last bracket and with comma
path("<slug>", posts_detail), #, name = "unique_slug"__<<
The second mistake you made is that you havent defined the slug type which is an important point
