I am currently working on django , Need some help how to achive my below goal

I need to publish the latest data and list data in a web app .

Below is the set of steps i followed

Created the Model.py

import datetime from statistics import mode from django.db import models

Create your models here.

class documents(models.Model):
    author= models.CharField(max_length=30)
    title=models.CharField(max_length=50)
    description=models.TextField()
    creation_date=models.DateTimeField()
    update_date=models.DateTimeField()

View.py

from django.shortcuts import render

from django.views.generic.list import ListView
from .models import documents

    # Create your views here.
    
    
    
    
    class documentlist(ListView):
        template_name='app/document_list.html'
        model=documents
        context_object_name='document'

HTML snippet

{% extends 'base.html' %}


{% block title %} MY HOMEPAGE {% endblock  %}

{% block css %}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" 
integrity="sha384-Gn5384xqQ1aoWXA 058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

{% endblock  %}


{% block content %}


<nav >
    <a  href="#">MEDICARE</a>
  </nav>

{% for d in document  %}

 <td>{{d.title}}</td>

{% endfor %}

{% endblock %}

How can we render both latest data and list of data from a model class in django?I am clear about rendering the list data using listview . can someone help in understanding how to display the latest data from the list to the listview.html

Thanks,Sid

Well you would go about getting your recent publish data in your listview like this:

class documentlist(ListView):
        template_name='app/document_list.html'
        model=documents
        context_object_name='document'
        
        def get_queryset(self):
            return documents.objects.filter(author=request.user).order_by('creation_date')

in your html template you can do something like this to render the latest post

% extends 'base.html' %}


{% block title %} MY HOMEPAGE {% endblock  %}

{% block css %}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" 
integrity="sha384-Gn5384xqQ1aoWXA 058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

{% endblock  %}


{% block content %}


<nav >
    <a  href="#">MEDICARE</a>
  </nav>

{% for doc in document  %}

 <td>{{doc.title}}</td>

{% endfor %}

{% endblock %}

Just add ordering by id in descending order:

 class documentlist(ListView):
        template_name='app/document_list.html'
        model=documents
        context_object_name='document'

        ordering = ['-id']

I have figured out the issue and this helped me resolve the issue.

 def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['latest_post'] = documents.objects.latest('update_date')
        return context

Thanks, SIdh
