Django paginate huge millions data

Django, CSRF, iFrames and Safari
The question here is similar to the one referred to by the link below but this link is 8 years old, python, Django and Safari have all moved one since then. I would like to know if the solution is still relevant or if there is a new way of solving this. Also, these solutions do not describe the resolution in detail. Django Iframe Safari Fix The problem: When a view has an iFrame loaded from a non-same-site and that iFrame attempts to write to a cookie, Django logs the user out. Thanks! -

How can I handle POST data in django middleware?
I have Django middleware to handle POST request. class MyMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, req): response = self.get_response(req) # want to do something with 'r.body', # but it is not able to be read return response As the request body is already read in get_response, I cannot read it again in middleware. Tried copy.copy(), but no luck since the copied stream references same object of the original one. copy.deepcopy() raises an exception. How can I handle POST data in middleware? I want to handle all requests, so implementing the logic in every view is not ideal. -

Django dynamic Search View based on filled GET request keys
please how is possible in Django to reach a view, which will be filtering based on filled keys from GET request?

Sweet Alert is not working inside ajax calls in django
Sweet Alert - https://sweetalert.js.org/guides/ I have imported Sweet Alert using CDN inside my base html file: <script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script> I have tried to use Sweet Alert inside ajax calls in the following way: $.ajax({ type:'POST', url: 'deliveryupdate/'+barcode2+'/', dataType: 'json', data:{ barcode: barcode2, owner: owner2, mobile: mobile2, address: address2, atype: atype2, status: "Gecia Authority Approved", statusdate: today, csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val() }, success: function(){ console.log("success log"); swal("Success!","Asset request has been approved","success"); }, error: function(){ console.log('error', arguments) swal("Error!","Some error occurred","error"); } }); This is not working, even though there are successful changes in the database, the error function is executing instead of success function, and the error sweet alert flashes for a mini-second and vanishes. The console shows error log. But if I change sweet alert to normal browser alert, it works perfectly.( but that too only in Chrome, not in firefox ) Its working perfectly when I replace swal() with alert(). (only in Chrome though) I don't want the normal browser alert, I need a good looking alert like Sweet Alert. In my other templates where there are no ajax calls and simple alerts, sweet alert is working fine with no problems. Please Help. -
