Changing the default authentication message in django-rest-framework
In a simple TokenAuthentication system in Django Rest Framework, the default message when you fail to send a proper authorization token is this { "detail": "Authentication credentials were not provided." } I want all my API responses to follow a certain template e.g. { success, message, data } How can I overwrite this error message? What is the best practice when creating these API templates? P.S. I checked out other questions but couldn't find anyone with a similar problem. If it was already answered I'd be glad if you could point me to it. -
How can I read a dicctionary in template in Django
Hi I'm trying to read a dicctionary in a template in django, but I would like to separate the keys and the value, the key is what will be showed, and the value is the next url it has to go (I know that diccionary is a little bit strage but I think that's not a problem.

DJANGO-User switch account issue
I noticed that when I am logged in as my profile (http://127.0.0.1:8000/user/admin/ ) and I go to my template where I have the list of all users ( http://127.0.0.1:8000/users/ ) and I click on another user(mattia_mibe) to see his/her profile it switched my account, so I don't see his/her profile but I see my profile (admin) with all my descriptions but at the same time the url is http://127.0.0.1:8000/user/mattia_mibe/ and it recognize @mattia_mibe as users, even what it displays is my profile's descriptions(admin).

How to change button text onclick using django?
I'm working on a school project and I'm trying to change a button's innerHTML to a value I got from a dictionary in views.py. However, when I load the page with this code: <script> var docFrag = document.createDocumentFragment(); for (var i=0; i < 3 ; i++){ var row = document.createElement("tr") for (var j=0; j < 3 ; j++){ var elem = document.createElement('BUTTON'); elem.type = 'button'; elem.id = 'r'+i+'s'+j; elem.value = 'r'+i+'s'+j; elem.onclick = function () { document.getElementById("klik").value = this.id; document.getElementById("ID").value = this.id; document.getElementById("klik").submit(); var id = this.getAttribute('id'); var novi = document.createElement('BUTTON'); novi.type = 'button'; //alert("This object's ID attribute is set to \"" + id + "\".") novi.value = id; novi.innerHTML = {{vrijednost}}; this.parentElement.replaceChild(novi,this); }; elem.innerHTML = elem.value; docFrag.appendChild(elem); } document.body.appendChild(docFrag); document.body.appendChild(row); } </script> Nothing happens. The page is blank. When I change novi.innerHTML to something else, 'x' for example, the x appears for a very short time and then it disappears.

Firebase and Django API
I'm want to start coding web platform(and perhaps later also make a mobile app for iOS and Android) and I recently started considering using Firebase. I really want to use its auth system, database system, and file storage system. I'm not really good at DevOps and I feel like Firebase can really make my life better. I want to use Django to create API and React with Next.js for frontend. API will have to do a few things with data, manage user's access, and their possible actions. I'm confused after all I've read on the internet about Firebase. 1. My frontend and backend have to be hosted somewhere else or can I host them on Firebase. 2. Is it even possible to create a fully working API that uses Firebase systems? Would such a thing be efficient? And how could I do that? And the most important question: Is using Firebase like that expensive? Will I not overpay? Maybe some of you have actual commercial experience with Firebase. -

How to correctly override account-confirm-email view for django-rest-auth package
I try to write api using djangorestframework and django-rest-auth. Almost all the urls working correctly, but account-confirm-email.
