Great video as always. Here's a simpler way to do the pagination. the Paginator class has a page range property you can use. {% for page in page_obj.paginator.page_range %} {{ page }} {% endfor %}
This is great Steven, but what if u have like 20pages and u want to truncate your pages so as all of the pages do not iterate out. so more like (2, 3, 4 .... 17, 18, 20) instead of (1-20)
@@isaiaholaoye2786.... to truncate, note sure if a shorter way, but i've added on to what Steven kindly provided, down to 3 in below (1,2,3....18,19,20) and my object called items instead of page_obj: {% if items.paginator.num_pages > 3 %} {% for page in items.paginator.page_range|slice:":3" %} {{ page }} {% endfor %} ... {% for page in items.paginator.page_range|slice:"-3:" %} {{ page }} {% endfor %} {% else %} {% for page in items.paginator.page_range %} {{ page }} {% endfor %} {% endif %}
Enjoying the series, thanks. Here's a way to add disabled to the previous button. Modify the next button loop accordingly... {% if venues.has_previous %} « First Previous {% elif not venues.has_previous %} Previous {% endif %}
If you use the the code below you will achieve that. I have not yet figured out how to show though as @DavossSeaworth asked.
{% if leads.has_previous %} « First Previous {% endif %} {% for page in leads.paginator.page_range %} {{ page }} {% endfor %} {% if leads.has_next %} Next Last » {% endif %}
I am using paginator in my list view. Every page listed 10 item. If I edit an item from page 5 then I want to redirect back to page 5. Right if I edit an team from page 5, it's redirecting me every time in page 1
I just cannot seem to get the style to work right on my own app. Don't get any of the grid, and borders around each page number, and selected page seems to raise up a bit. I know the bootstrap include is right because if i just paste in the example it makes it correct, but can't get it to work around my data.
There is one thing i still have an issue: when you have a lot of entries, the page counter below keeps spawning numbers, saturating the page. How can i make the numbers bar to show, i dont know, 10 pages, but having a button to show the next(or previous) 10?
Great video. I'm a big fan of this series. One question. This approach would fit for big data operations? For example, let's suppose that we wanna get 10K venues (or anything else) for our list. This probably would overload the navigator that would probably crash at some moment. For this kind of purpose I would do the pagination routine from the scratch inside of the views. Like telling which window of data I wanna to get and not using the objects.all() method . Could you suggest an alternative on how to do this operation in a more automatic way?
@@Codemycom For large amount of data unfortunately it will. Or at the very least would take some time until finish load everything up. But thanks for the feedback anyway.
Nice explanation, So far you explain everything nicely. But what if, we have, let's say 1000 entries in our venue and we are showing 20 per page, in this case our pagination will show 50 numbers like: | first | | previous | |1| |2| |3| |4| |5| |6| |7| |8| |9| |10| |11| |12| |13| |14| |15| |16| |17| |18| all the way to 50 |Last| : Which will not look good on web page, so how can we limit it? Like, we can show first 5 pages and last five pages: | first | | previous | |1| |2| |3| |4| |5| | .. | |47| |48| |49| |50| |Last|
{% if page.has_previous %} First Previous {% elif not page.has_previous %} First Previous {% endif %} {% for n in page.paginator.page_range %} {% if page.number == n %}
{{ n }}
{% elif n > page.number|add:'-3' and n < page.number|add:'3' %} {{ n }} {% endif %} {% endfor %} {% if page.has_next %} Next Last {% elif not page.has_next %} Next Last {% endif %}

It's a fantastic tutorial. Thanks a lot, sir!
You're very welcome!
I don't like doing frontend but with Your tutorials this is very easy job :)
Thanks!
Loved that special Hack, I've added it to an App I've been building. Thanks
Glad you liked it!
Hey John, All I gotta say is: "Clever hack!!"
Ha, thanks!
very good. you are realy teacher.
"Very Cool"😎
Thanks!
great
thanks
its good ,please can make it max screen size .
What do you mean?
Fantastic!!
Thanks!
i wanna know how to make the current page number highlated ... when highlating current page all the other pages gets highlated as its in for loop

Hello Abdul do you find how to do that please ?
I am using paginator in my list view. Every page listed 10 item. If I edit an item from page 5 then I want to redirect back to page 5. Right if I edit an team from page 5, it's redirecting me every time in page 1
Good course man
Thanks!
we could have assigned a list [ 1 , 2 , 3 , .... number of pages] and iterate through its elements
try it
I just cannot seem to get the style to work right on my own app. Don't get any of the grid, and borders around each page number, and selected page seems to raise up a bit. I know the bootstrap include is right because if i just paste in the example it makes it correct, but can't get it to work around my data.
Sounds like maybe you need a course in basic HTML
There is one thing i still have an issue: when you have a lot of entries, the page counter below keeps spawning numbers, saturating the page. How can i make the numbers bar to show, i dont know, 10 pages, but having a button to show the next(or previous) 10?
you can try iterating through this one "Paginator.get_elided_page_range(number, *, on_each_side=3, on_ends=2)" but it requires djagno 3.2

@@aimlezz8855 Perfect!
Great video as always. Just one quick thing, how can I make the pagination for say 300 pages?
in the same way
Great video as always...but i have a problem ,This does not move to the other page, I tried to change the page number in the path,but it is fixed on the first page
this code:
def list_venues(request):
venue_list = Venue.objects.all()
p = Paginator(Venue.objects.all(), 2)
page = request.GET.get('page')
venues = p.get_page(page)
nums = "a" * venues.paginator.num_pages
return render(request,'events/venue.html',
{'venue_list':venue_list,
'venues':venues,
'nums': nums})
Can you do a video about this pagination logic with 2 django code bases, 1 produce REST api and another consume the api
Had already done this but the only part pending was the number thing you did.. thanks..
Cool
thank you so much for all the videos! where can I find the codes?
In the pinned comment just like I said in the video..
But what if we have 100 page then this should work or not
What does the number of pages have to do with it?
First Like, first comment, bro pls make a Kivy Translator app video bro.
No, I won't be doing that
i need a help.
i go warnning
