I hope you can help me, as part of my project in Django, I must show specific data of my table which is in BD Postgresql, but I do not know how to do it and the truth is that with the Tutorials I get too involved. My code is as follows: base.Html: {% block container%} {% block title%} General Warehouse {% endblock%}
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
{% load static %}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="{% static 'boostrap/css/bootstrap.css' %}">
</head>
{% endblock container %}
{% block navegacion %}
<marquee bgcolor="#006699" behavior="alternate" direction="right">
<b><font color="#FFFFCC" size="5"><h1>Almacen General</h1></font></b>
</marquee>
<style type="text/css">
* {
margin:0px;
padding:0px;
}
#header {

The idea is that when you select Warehouse, this only brings me all the items that meet that condition: For example, when I select store sales, this one brings me all the articles that correspond with that classification.
I do not know if you can help me with this information.
