When I try to render template passing argument with primary key or ID CSS not loading as expected but when I try to render it simply with a request without passing id arg it loads perfectly.

viewsy.py

def update_lead(request,pk):
    leads = Lead.objects.get(id = pk)
    followup = Followup.objects.all
    agent = Agent.objects.all
    source = Source.objects.all
    print(f"the leads are {leads}")
    context = {"lead":leads,"followup":followup,"agent":agent,"source":source}
    
    return render(request,"home/update_lead.html",context)

This is how looks at the frontend when I try passing id with my view it is not loading the css which is expepcted enter image description here

it is showing error enter image description here

but if we just remove the use of pk then the css will be loading

and it is supposed to look like enter image description here

here is my templates code

{% extends 'base.html' %}

{% block body %}
<div class="container">
  <h2>Create Lead</h2>
  <form action="creat_handle_lead" method="POST">
    {% csrf_token %}
    <div class="form-row">

        <input type="text" class="form-control" id="inputEmail4" required name="name" value="{{lead.name}}">
      </div>
      <div class="form-group col-md-6">

You are loading the static files with:

<script src="../static/elegant/vendor/jquery/jquery.min.js"></script>

If the URL looks like leads/52, then it will load from leads/static/elegant/vendor/jquery/jquery.min.js which is not what we are looking for. This originates from the fact that .. moves one level up, so if we work with foo/bar/, then starting with .. will result in foo/static/elegant/…. But if the path is foo/bar/qux, it will thus aim to load data with foo/bar/static/elegant/… as path.

You can work with an absolute path, and thus implement this as:

<script src=/static/elegant/vendor/jquery/jquery.min.js"></script>

or even better, make use of the {% static … %} [Django-doc] template tag:

<script src={% static 'elegant/vendor/jquery/jquery.min.js' %}"></script>

It will then prepend the parameter with the value of the STATIC_URL setting [Django-doc], which makes it easy to later change the static URL.

You will need to update all the items with a ../static/ prefix.
