Django: Old url is still searched after POST request
I am fairly new to Django and now at my wit's end with the following issue. I have changed the url name from 'odata' to 'database' and the app properly redirects to the url http://127.0.0.1:8000/database/. However while being at http://127.0.0.1:8000/database/ and making the POST request using ajax, the app freezes and on looking in the browser's developer tools I see the error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/odata/ . . . The current path, odata/, didn't match any of these. Why the old name is still being searched? I have made changes in the following files and codes: my_app/url.py urlpatterns = [ path('', views.view1, name = "view1"), path('database/', views.view2, name = "view2"), #old name was odata/ ] myreq.js function submit_training() { $.ajax({ url: '/database/', //earlier- /odata/ data: $('form#db_settings').serialize(), method: 'POST', ... } When I revert the changes to 'odata' everything works as expected. I am not sure what I am missing here. I apologize for not providing more or exact codes, as I am not supposed to disclose details on the project. However, I can still furnish more information, if required. Your time and help is much appreciated!! -

DjangoRestFramework: Assign CustomUser failed

Passing a variable vs a hard-coded string is not working on query search using Django shortcuts
I'm in the process of learning how to use Django. My goal is to grab an object (one hero and one villain) from the database using the names, (not id), passed in the URL as search params. I am successfully grabbing the values from the query params, however, when I try to pass the variable "hero" into the Django shortcut, (get_object_or_404(Super,name=hero)), I get a 'not found'.
