TypeError: Password must be a string or bytes, got BoundField

Question

I am creating a login page. There I want to receive json format at backend, with fields username and password in string format. But when I try to authenticate username and password (in views.py). I get the following error:

TypeError: Password must be a string or bytes, got BoundField.

views.py

from .serializers import event_serializer, student_serializer
from rest_framework.decorators import api_view
from rest_framework.response import Response
from rest_framework import status
from django.contrib.auth import authenticate, login, logout
from django.db import IntegrityError

@api_view(['POST', 'GET'])
def login_view(request):
    if request.method == "POST":
        serializer = student_login_serializer(data=request.data)
        if serializer.is_valid():
            print("serializer is valid")
            username_pwd = serializer
            username = username_pwd["username"]
            password = username_pwd["password"]
            student = authenticate(request, username=username, password=password)
            if student is not None:
                login(request, student)
                events = Event.objects.all()
                serializer = event_serializer(events, many=True)
                return Response(serializer.data, status=status.HTTP_202_ACCEPTED)
            else:
                return Response(serializer.data, status=status.HTTP_401_UNAUTHORIZED)
        return Response(serializer.errors, status=status.HTTP_401_UNAUTHORIZED)
    elif request.method == "GET":
        users = Student.objects.all()
        serializer = student_serializer(users, many=True)
        return Response(serializer.data)

serializers.py

from rest_framework import serializers
from .models import Student, Club, member_request, Event, Comment
from django import forms

class student_login_serializer(forms.Form):
    username = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Username'}))
    password = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Password'}))
    fields = ['username', 'password']

models.py

from django.contrib.auth.models import AbstractUser
from django.db import models

class Student(AbstractUser):
    pass

Please feel free to ask me for more details regarding this problem and thanks in advance.

Yes it's true because your serializer return html element. So, authenticate function was not work properly.

In Your case serializer return this:

> Username: type="text" name="username" value="pradip" placeholder="Username"
> required id="id_username">  for="id_password">Password: name="password" value="admin123@" placeholder="Password" required
> id="id_password">

Try this:

    @api_view(['POST', 'GET'])
    def login_view(request):
        if request.method == "POST":
            serializer = student_login_serializer(data=request.data)
            if serializer.is_valid():
                print("serializer is valid")
                student = authenticate(username=request.data.get('username'),password=request.data.get('password'))
                if student is not None:
                    login(request, student)
                    events = Event.objects.all()
                    serializer = event_serializer(events, many=True)
                    return Response(serializer.data, status=status.HTTP_202_ACCEPTED)
                else:
                    return Response(serializer.data, status=status.HTTP_401_UNAUTHORIZED)
            return Response(serializer.errors, status=status.HTTP_401_UNAUTHORIZED)
        elif request.method == "GET":
            users = Student.objects.all()
            serializer = student_serializer(users, many=True)
            return Response(serializer.data)
