I can't find out my mistake in displaying database data in django template

Question

I am working on a Django project. I have to display database data in the Django template but I can't find out my mistake in my code that is not allowing me to display data on the HTML page.

views.py

def viewposts(request):
     posts = NewPost.objects.all()

     return render(request,"network/index.html",{
         "posts" : posts,
     })

Here is my model:

models.py

class NewPost(models.Model):
    user = models.ForeignKey(User, on_delete = models.CASCADE)
    post = models.TextField()
    timestamp = models.DateTimeField(auto_now_add = True)

    def __str__(self):
         return f"post : {post} || user: {user} || timestamp: {timestamp} "

HTML template

<div id="posts">
        {% for posts in posts %}
            <ul>
                <li>
                    <h4>{{ posts.user }} || {{ posts.timestamp }}</h4>
                    <h3>{{ posts.post }}</h3>
                </li>
            </ul>   
        {% empty %}
            <h6>No post availabel 😔</h6>
        {% endfor %}
    </div>

urls.py

urlpatterns = [
   path("", views.index, name="index"),
   path("login", views.login_view, name="login"),
   path("logout", views.logout_view, name="logout"),
   path("register", views.register, name="register"),
   path("index/",views.NewPostMaker,name="post"),
   path("index/",views.viewposts,name="posts")
]

I know I have done a silly mistake on any part of my code but I can hardly find it out. When I fill-up the form, data is stored in the database but I can't display them on the HTML page.

You have two index/ patterns, hence it will fire the NewPostMaker, not the viewposts. — willeM_ Van Onsem

You defined two paths for index/. This means that if the user visits the index/ URL, the first view will "fire" and render the template. As a result it will fire NewPostMaker, not viewposts.

You thus should define one view, where you probably will have to merge the logic of the two views into one, and thus implement this as:

urlpatterns = [
   path('', views.index, name="index'),
   path('login', views.login_view, name='login'),
   path('logout', views.logout_view, name='logout'),
   path('register', views.register, name='register'),
   path('index/', views.viewposts, name='posts')
]
