pagination of a specific context in multiple context in ListView not working in django?

[Ali Ahammad]

in django, i am trying to list some queries of several objects like user lists, 
categoies and Post list. the homepage will be contained couple of blocks or 
boxes. each box will have different query list like Post list, User List, 
category list. But only one context will have pagination and other won't and 
ofcourse the pagination will be working on Post list.

here is the views.py:

class BlogappListView(ListView):
model = Category,CustomUser
template_name = 'home.html'
context_object_name='category_list'
queryset=Category.objects.all()
paginate_by = 2

def get_context_data(self, **kwargs):
context = super(BlogappListView, self).get_context_data(**kwargs)
context['user_list']= CustomUser.objects.all()
context['post_list']=Post.objects.all()
activities=context['post_list']
return context
def get_related_activities(self,activities):
queryset=self.objects.activity_rel.all()
paginator=Paginator(queryset,2)
page=self.request.GET.get('page')
activities=paginator.get_page(page)
return(activities)
in urls.py:

urlpatterns = [
path('',BlogappListView.as_view(),name='home'),
]
in base.html, the paginate portion code:

  
  {% if is_paginated %}

{% if page_obj.has_previous %}
  
First
  
  
  Previous

{% endif %}

{% for num in page_obj.paginator.page_range %}
  {% if page_obj.number == num %}
  
{{ num 
}}
  

  {% elif num > page_obj.number|add:'-3' and num < 
page_obj.number|add:'3' %}
  
{{ num 
}}


  {% endif %}
{% endfor %}

{% if page_obj.has_next %}

  Next

  
  Last


{% endif %}

  {% endif %}

the main problem is that page number 1 is showing all the posts and also the 
second page. and category list is also truncated into 2 but the user list ok.

so how can i make it work ? is there any other way?

thank you in advance

You can't. However you try to implement that will be extremely 
unreliable and the client can spoof it anyway if they choose to do that.


Make the client login/employee check-in and out with some normal 
authentication mechanism. It's much easier so need to waste a lot of 
time trying to implement something that will never work anyway.


If you want to make some kind of tracking/surveillance system I'm sure 
you can do that but this is not the way to go.


Kind regards,

Re: Issue with serving angular with django

[Andréas Kühne]

Hi Sunday,

No - you don't. What collectstatic does is it collects all of the static
files to the path where they should be stored. This should be a directory
that should be served from nginx or apache or any other webserver. When you
run manage.py runserver - you run a development server that isn't geared
for production. And that is what is serving the files when "DEBUG" is set
to True.

To make it work like you want it to:
1. Install a webserver that can serve the static files.
2. Install gunicorn, uwsgi or some other wsgi server to serve the django
application.

When you have that working you will be able to look at your custom error
pages and so on.

There are many good tutorials on howto set this up - I usually look at
digitalocean - check here for example:

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04

You can also look at the official django docs for explaining how to run
production loads:
https://docs.djangoproject.com/en/3.0/ref/django-admin/#runserver
https://docs.djangoproject.com/en/3.0/howto/deployment/wsgi/

When you get this working - serving the static files from a webserver isn't
that hard.

Regards,

Andréas

Re: Django Pagination

[maninder singh Kumar]

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 !

willy

Re: Issue with serving angular with django

[Chetan Ganji]

You should use nginx to serve angular n static files and gunicorn for python

Below tuts might help you.

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04

Look for a tutorial without docker.

This might be relevant:

But of course, without knowing what you have done or seen any of your 
code it is very hard to help you.


Kind regards,

You haven't described how you are currently serving static files with 
Django. I suggest you start by reading this:


https://docs.djangoproject.com/en/3.0/howto/static-files/deployment/

You definitely shouldn't use DEBUG in production and you definitely 
should serve static files with your web server of choice.

Issue with serving angular with django

[Sunday Iyanu Ajayi]

Hi guys,

I am working on a project which is made up of an angular and a django part.

- The frontend dev develops the frontend, makes a build and forwards to me

- I get the build and serve it using python manage.py collectstatic

But my challenge is that
 1. It only works when debug is set to True
 2. If debug is set to True, I am unable to set or customize my  error
pages ( it shows django error messages with some vital information that
makes my site vulnerable.

Please What am I doing wrong? Or are there better ways of serving angular
build files on django?

Thank you.

Regards,
