How to create if statement on a redirect to change Django model

I am trying to create a if statement in my Django view that detects when I am redirected to my complete order url. I want to do this because I would like to change my Django model Order 'complete' field to true. My redirect is coming from a javascript function in my paypal intergration.
checkout.html
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<h1>Checkout</h1>
<div class='container'>
<div class='row'>
<div class='col-6'>
<form action="" method='post' id='payement-form'>
{% csrf_token %}
<!-- {{ form|crispy }} -->
<div class='col-12' id='paypal-button-container'></div>
</form>
<script
src="https://www.paypal.com/sdk/js?client-id="> // Required. Replace YOUR_CLIENT_ID with your sandbox client ID.
</script>
<script>
function redirect() {
var url = "{% url 'complete-order' %}"
window.location.href = url
}
paypal.Buttons({
createOrder: function (data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
value: '0.01'
}
}]
});
},
onApprove: function (data, actions) {
// This function captures the funds from the transaction.
return actions.order.capture().then(function (details) {
// This function is the redirect
redirect()
alert('Transaction completed by ' + details.payer.name.given_name);
});
}
}).render('#paypal-button-container');
</script>
</div>
{% endblock content %}
views.py
#login_required(login_url='login')
def checkout(request):
order = Order.objects.get(user=request.user, complete=False)
context = {
'order': order
}
return render(request, 'videogames/checkout.html', context)
#login_required(login_url='login')
def paymentComplete(request):
order = Order.objects.get(user=request.user, complete=True)
context = {
'order': order
}
return render(request, 'videogames/complete.html', context)

There are many ways that should be selected according to your project.
before redirection, in the view , call a link with Ajax to change the status
#login_required(login_url='login')
def paymentSetComplete(request):
order = Order.objects.get(id=request.payment_id=,user=request.user, complete=False)
order.complete=True
order.save() # or update directly
return
Change the status when the request to load the complate page was sent to django
I do not know what measures you have taken to secure and prevent the fake purchases
But know that users can repeat requests that come to the server

Anybody see the problem? #Bootoast script

Trying to get Bootoast to work on my website, where I try to pass a message. You can see the code below. Using Django-bootstrap for front-end.
BASE.HTML
<script srs="https://unpkg.com/bootoast#1.0.1/dist/bootoast.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/bootoast#1.0.1/dist/bootoast.min.css">
<script>
function toast(message, type) {
bootoast.toast({
position: 'bottom-center',
message,
type,
});
}
{% if messages %}
{% for message in messages %}
toast('{{ message }}', '{{ message.tags }}')
{% endfor %}
{% endif %}
</script>
VIEWS.PY
#login_required(login_url="/sign-in/?next=/customer/")
def profile_page(request):
user_form = forms.BasicUserForm(instance=request.user)
customer_form = forms.BasicCustomerForm(instance=request.user.customer)
if request.method == "POST":
user_form = forms.BasicUserForm(request.POST, instance=request.user)
customer_form = forms.BasicCustomerForm(request.POST, request.FILES, instance=request.user.customer)
if user_form.is_valid() and customer_form.is_valid():
user_form.save()
customer_form.save()
messages.success(request, 'Your profile has been updated')
return redirect(reverse('customer:profile'))
return render(request, 'customer/profile.html', {
"user_form": user_form,
"customer_form": customer_form
})
So the error I'm getting is this:
(index):197 Uncaught ReferenceError: bootoast is not defined
I'm blind or isn't this defined?

<script srs="https://unpkg.com/bootoast#1.0.1/dist/bootoast.min.js"></script>
Should have been
<script src="https://unpkg.com/bootoast#1.0.1/dist/bootoast.min.js"></script>

How to fix matchong query does not exist error?

I have been working on a like system using django and ajax, this like system is very similar to instagram's one. After finishing with the code I started to get a Post matching query does not exist error which has been a pain. I dont see the wrong in my code but I think the problem is on the views.py file because the traceback is triggering a line there. How can i fix this error?

I'm not sure what it says in the traceback. If you could provide that, maybe it'll make more sense. But I assume it's because of the like post_obj = Post.objects.get(pk=pk) in
def like_post(request) function.
Post with the given primary key does not exist. What you can do is to check if the pk exists.
if Post.objects.filter(pk=pk).exists():
# it exist
or you can do a try except method
try:
post_obj = Post.objects.get(pk=pk)
if user in post_obj.liked.all():
post_obj.liked.remove(user)
else:
post_obj.liked.add(user)
except:
# what happens if post does not exist

Symfony 3 Infinite Scrolling Ajax

I'm trying to make an infinite Scrolling in Ajax.
I really don't know what is missing.
Html Index:
<div class="container">
<!-- Menu -->
{% include '::announce/menu.html.twig' %}
{% for announce in announces|slice(0, 4) %}
<!-- Announce Preview -->
{% include '::announce/' ~ game ~ '/preview.html.twig' %}
{% endfor %}
</div>
<div id="content"> loop content </div>
<nav id="pagination">
<p>Page 2</p>
</nav>
{% endblock %}
{% block javascripts %}
<script src="{{ asset('js/jquery-ias.min.js') }}"></script>
{% endblock %}
My controller index:
public function indexAction(Request $request, $game)
{
$em = $this->getDoctrine()->getManager();
$announces $em->getRepository('PlatformBundle:Announce')->byGame($game);
return $this->render('announce/index.html.twig', array(
'announces' => $announces,
'game' => $game
));
}
With this i have my index page with 4 announce
Now i show you my code for scrolling and adding more announce
Ajax File:
$(window).scroll(function () {
if($(window).scrollTop() + $(window).height()>= $(document).height()){
getmoredata();
}
})
function getmoredata() {
$.ajax({
type: "GET",
url: "{{ path('announce_page', {'id': '2', 'game': game}) }}",
dataType: "json",
cache: false,
success: function (response) {
$("#content").append(response.classifiedList);
$('#spinner').hide();
console.log(response);
},
error: function (response) {
console.log(response);
}
});
}
And this is the controller for page:
public function pageAction(Request $request, $game)
{
$em = $this->getDoctrine()->getManager();
$announces = $em->getRepository('PlatformBundle:Announce')->byGame($game);
$list = $this->renderView('announce/result.html.twig', array(
'announces' => $announces,
'game' => $game
));
$response = new JsonResponse();
$response->setData(array('classifiedList' => $list));
return $response;
}
Last code, it's the html content for ajax (result.html.twig)
{% for announce in announces|slice(4, 4) %}
<!-- Affichage Annonce -->
{% include '::announce/' ~ game ~ '/preview.html.twig' %}
{% endfor %}
For resume, i have my index with 4 announce, when i scroll in bottom, i have a positive ajax request without error. But nothing appear after the 4 announce.
If i go to announce page 2 directly with pagination, i can see 4 other announce. So my routing is working but something don't works in ajax code i think.
Any idea? :)
Thanks

Submit button for a formset doesn't work when generated by ajax [duplicate]

This question already has answers here:
Event binding on dynamically created elements?
(23 answers)
Closed 5 years ago.
I have a formset to update my models and I display forms from my formset based on the search query. I have an ajax keyup function to send post requests so I can generate search_results.html that I then pass to in search.html.
Now, if I generate the forms dynamically the submit button does not work. If I ditch the search and pass the content of search_results.html to search.html directly it does work.
I have two views, SearchReportView which supposed to be the main one, and SearchReports to handle generating the report. I guess I might just merge them at this point - it doesn't solve my problem though.
Also I had this working before when I used multiple forms but I had to switch to a formset.
body of search.html
<div class="container">
