Недействительные учетные данные даже при введении правильных учетных данных django

Я создал форму входа для моего пользователя, и когда я пытаюсь войти в систему, он говорит, что недействительный идентификатор студента или пароль, хотя я правильно ввел свои учетные данные. Я использую postgresql через Railway. Я новичок (https://i.stack.imgur.com/iRQcJ.png)

Это мой файл forms.py

from django import forms
from django.forms import ModelForm
from .models import StudentInfo

class StudentInfoForm(forms.ModelForm):
    class Meta:
        model = StudentInfo
        fields = ['student_id', 'firstname', 'lastname', 'middlename', 'course','year', 'section', 'password', 'confirm_password',]
        widgets = {
            'password': forms.PasswordInput(),
            'confirm_password': forms.PasswordInput()
        }
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['student_id'].required = True
        self.fields['firstname'].required = True
        self.fields['lastname'].required = True
        self.fields['course'].required = True
        self.fields['section'].required = True
        self.fields['password'].required = True
        self.fields['confirm_password'].required = True

class SignInForm(forms.Form):
    student_id = forms.CharField(label='Student ID', max_length=10)
    password = forms.CharField(label='Password', widget=forms.PasswordInput)

Это мой models.py

from django.db import models
from django.contrib.auth.hashers import make_password

# Create your models here.

class StudentInfo(models.Model):
    student_id = models.CharField(max_length=10, unique=True, primary_key=True)
    firstname = models.CharField(max_length=100)
    lastname = models.CharField(max_length=100)
    middlename = models.CharField(max_length=100, blank=True, null=True)
    course = models.CharField(max_length=100)
    year = models.CharField(max_length=1)
    section = models.CharField(max_length=1)
    password = models.CharField(max_length=128, null=True)
    confirm_password = models.CharField(max_length=128, null=True)

    def __str__(self):
        return f"{self.firstname} {self.lastname}"
    
    def save(self, *args, **kwargs):
        self.password = make_password(self.password)
        super(StudentInfo, self).save(*args, **kwargs)

Это мой urls.py

from django.urls import path

from . import views

urlpatterns = [
    path("home/", views.home, name="home"),
    path("index/", views.index, name="index"),
    path("signin/", views.signin, name="signin"),
    path("signup/", views.signup, name="signup"),
    path("dashboard/", views.dashboard, name="dashboard")
]

Это мой views.py

from django.shortcuts import render,redirect
from .forms import StudentInfoForm, SignInForm
from .models import StudentInfo
from django.contrib.auth.hashers import check_password
from django.contrib.auth import authenticate, login
from django.contrib import messages

# Create your views here.

def home(request):
    return render(request,"signin/home.html")

def index(request):
    return render(request,"signin/index.html")


def signup(request):
    if request.method == "POST":
        form = StudentInfoForm(request.POST)
        if form.is_valid():
            password = form.cleaned_data.get('password')
            confirm_password = form.cleaned_data.get('confirm_password')
            if password != confirm_password:
                # Passwords don't match, render the form again with an error message
                form.add_error('confirm_password', 'Passwords do not match')
                return render(request, 'signin/signup.html', {'form': form})
            else:
                form.save()
                return redirect('signin')
    else:
        form = StudentInfoForm()
    return render(request, 'signin/signup.html', {'form':form})



def signin(request):
    error_message = None  # Define error_message outside the if block

    if request.method == 'POST':
        form = SignInForm(request.POST)
        if form.is_valid():
            student_id = form.cleaned_data.get('student_id')
            password = form.cleaned_data.get('password')
            # Authenticate user
            user = authenticate(request, username=student_id, password=password)
            if user is not None:
                # User is authenticated, create session
                login(request, user)
                return redirect('dashboard')
            else:
                error_message = "Invalid student ID or password."
    else:
        form = SignInForm()
    return render(request, "signin/signin.html", {'form': form, 'error_message': error_message})

def dashboard(request):
    return render(request, 'signin/dashboard.html')

Яm practicing and i отлаживаю это в течение длительного периода времени и все еще не могу найти ответ

from django.contrib.auth import authenticate, login

user = authenticate(request, username=student_id, password=password)

#and

login(request, user)
