Django 2 - pagination does not propperly work

first of all, thank for reading my question :) I'm currently working on a small Blog platform and i want to implement pagination for all my Post elemets. therefor i modified my view.py and the actual .html template. The problem now is that each time i visit the post_list.html page and i click on next nothing happends.. What the matter here:

post_list.html

{% extends 'quickblog/base.html' %}

{% block content %}
    {% for post in posts %}
        <br>
        <div class="post">
            <h1><u><a href="{% url 'post_detail' pk=post.pk %}">{{ post.title }}</a></u></h1>
            <p>{{ post.text|linebreaksbr }}</p>
            <div class="date">
                <a>published by: {{ post.author }}</a><br>
                <a>published at: {{ post.published_date }}</a><br>
                <a>tags: {{ post.tag }}</a>
            </div>
        </div>
    {% endfor %}
        <div class="pagination">
        <span class="step-left">
         {% if posts.has_previous %}
            <a href="?page=1">&laquo; first</a>
            <a href="?page={{ posts.previous_page_number }}">previous</a>
            {% endif %}

        <span class="current">
            Page {{ posts.number }} of {{ posts.paginator.num_pages }}.
        </span>

        {% if posts.has_next %}
            <a href="?page={{ posts.next_page_number }}">Next</a>
            <a href="?page={{ posts.paginator.num_pages }}">Last &raquo;</a>
        {% endif %}
    </span>
   </div>
{% endblock %}

views.py

def post_list(request):
    list_posts = Post.objects.get_queryset().order_by('created_date')
    paginator = Paginator(list_posts, 15)  # Show 15 Posts per page

    page = request.GET.get('posts')
    posts = paginator.get_page(page)
    return render(request, 'quickblog/post_list.html', {'posts': posts})

As pagination works on ordered data you need to either append order_by after your query or use default ordering in your models as specified in the below link

Hope this helps.

In your template you use page as query parameter. So you should use that in the view as well.

template:

<a href="?page={{ posts.next_page_number }}">Next</a>

view:

page = request.GET.get('page')  # not .get('posts')
