My asset_list html is like this

{% if user_role == 'admin' %}
        {% include 'asset_mng/admin_sidebar.html' %}
    {% elif user_role == 'asset_owner' %}
        {% include 'asset_mng/asset_owner_sidebar.html' %}
    {% endif %}  
    <div class="right">
        <div class="search-container">
            <input type="text" id="searchInput" placeholder="Search by AssetName..." aria-label="Search">
            <button class="add-button" aria-label="Add Asset" id="addUserButton"><i class="fas fa-plus"></i> Add</button>
        </div>

login database is like this , with roles admin and user

class UserDetails(models.Model):
    username = models.CharField(max_length=100, unique=True)
    password = models.CharField(max_length=100)  # Ideally, this should be hashed
    role = models.CharField(max_length=45)

login view.py

def asset_login(request):
    if request.method == 'POST':
            username = request.POST['username']
            password = request.POST['password']
            user = authenticate(request,username=username,password=password)
            try:
                user = UserDetails.objects.get(username=username, password=password)
                if user is not None:
                    request.session['username'] = user.username
                    request.session['role'] = user.role     #pass the user's role to the template
                    if user.role == 'admin':
                        return redirect('admin_dashboard')
                    elif user.role == 'head':
                        return redirect('head_dashboard')
                    elif user.role == 'asset_owner':
                        return redirect('asset_owner_dashboard')
                    elif user.role == 'ciso':
                        return redirect('ciso_dashboard')
                    else:
                        messages.error(request, 'Unknown user role')
                else:
                    messages.error(request, 'Invalid username or password')
            except UserDetails.DoesNotExist:
                messages.error(request, 'Invalid username or password')
    return render(request, 'asset_mng/asset_mng.html')

views for asset list

def asset_list(request):
    users = Asset_Table.objects.all()
    return render(request, 'asset_mng/asset_pro.html', {'users': users})

database to set on and off privilege

class AssetOwner_Privilege(models.Model):
    user = models.ForeignKey(UserDetails, on_delete=models.CASCADE)
    add_asset = models.BooleanField(default=False)

views for setting on and off in database

def privilege_asset_owner(request):
    username =request.session.get('username',None)
    if not username:
        return redirect('asset_login')
    user = UserDetails.objects.get(username = username)
    asset_owner, created = AssetOwner_Privilege.objects.get_or_create(user=user)
    if request.method == 'POST':
        add_asset = request.POST.get('add_asset') == 'on'
        asset_owner.add_asset = add_asset
        asset_owner.save()
        return redirect('privilege_asset_owner')
    return render(request, 'asset_mng/privilege_asset_owner.html', {
        'username': username,
        'add_asset': asset_owner.add_asset,
    })

i don’t understand what you want…

but, i know that how to check user info in template commend is {{ request.user.{attribute} }}.
like {{ request.user.user_role }} or {{ request.user.is_anonymous }}

And if what you want is to provide a specific service to only some users, it is better to check user permissions and perform the task in views.py rather than in the template.
