Django Pagination

[Akshat Zala]

Hello,

I am finding it difficult to paginate through all the posts

My views.py :

@login_required

def home_view(request):

"""Display all the post of friends and own posts on the dashboard"""

posts = Post.objects.all().order_by('-date_posted')

media: MEDIA_URL

# 'post':Post.objects.filter(Q(author=request.user) | Q(author__from_user=request.user) | Q(author__to_user=request.user)).order_by('-date_posted'),

paginator = Paginator(posts, 2)

page_number = request.GET.get('page')

page_obj = paginator.get_page(page_number)

return render(request, 'post/home.html',{'page_obj': page_obj})

and in template post/home.html:

{% if is_paginated %}

{% if page_obj.has_previous %}

<a class="btn btn-outline-info mb-4" href="?page=1">First</a>

<a class="btn btn-outline-info mb-4" href="?page={{ page_obj.previous_page_number }}"><span class="material-icons">arrow_left</span></a>

{% endif %}

{% for num in page_obj.paginator.page_range %}

{% if page_obj.number == num %}

<a class="btn btn-info mb-4" href="?page={{ num }}">{{ num }}</a>

{% elif num > page_obj.number|add:'-4' and num < page_obj.number|add:'4' %}

<a class="btn btn-outline-info mb-4" href="?page={{ num }}">{{ num }}</a>

{% endif %}

{% endfor %}

{% if page_obj.has_next %}

<a class="btn btn-outline-info mb-4" href="?page={{ page_obj.next_page_number }}"><span class="material-icons">arrow_right</span></a>

<a class="btn btn-outline-info mb-4" href="?page={{ page_obj.paginator.num_pages }}">Last</a>

{% endif %}

Thanks

Hi akshat,

What is the difficulty?

Where have you defined the variable   is_paginated? Is it present in the context?

Hi,

if I change the template to:

{% if not is_paginated %}

{% if page_obj.has_previous %}

<a class="btn btn-outline-info mb-4" href="?page=1">First</a>

<a class="btn btn-outline-info mb-4" href="?page={{ page_obj.previous_page_number }}"><span class="material-icons">arrow_left</span></a>

{% endif %}

{% for num in page_obj.paginator.page_range %}

{% if page_obj.number == num %}

<a class="btn btn-info mb-4" href="?page={{ num }}">{{ num }}</a>

{% elif num > page_obj.number|add:'-4' and num < page_obj.number|add:'4' %}

<a class="btn btn-outline-info mb-4" href="?page={{ num }}">{{ num }}</a>

{% endif %}

{% endfor %}

{% if page_obj.has_next %}

<a class="btn btn-outline-info mb-4" href="?page={{ page_obj.next_page_number }}"><span class="material-icons">arrow_right</span></a>

<a class="btn btn-outline-info mb-4" href="?page={{ page_obj.paginator.num_pages }}">Last</a>

{% endif %}

{% endif %}

It only shows pagination and posts are not seen in template.

Dear Sir,

it shows all the text on all the pages.

if there are total 5 posts, then it  shows all the 5 posts on all the pages.

Thanks,

I think there might be a way around, below is the code modified for views.py

@login_required

def home_view(request):

"""Display all the post of friends and own posts on the dashboard"""

posts = Post.objects.order_by('-date_posted')

media: MEDIA_URL

# 'post':Post.objects.filter(Q(author=request.user) | Q(author__from_user=request.user) | Q(author__to_user=request.user)).order_by('-date_posted'),

paginator = Paginator(posts, 2)

page_number = request.GET.get('page')

try:

page_obj = paginator.page('page')

except PageNotAnInteger:

page_obj = paginator.page(1)

except EmptyPage:

page_obj = paginator.page(paginator.num_pages)

return render(request, 'post/home.html',{'page_obj': page_obj})

I think this might work !
