Django change password link is not active?

I am learning an authentication in Django. Today I am stuck with this problem and I am not able to figure out how can I solve it. I want to make a form for password change. but the change form link is not active and I don't know how to fix it.
here is my views.py
#login_required
def user_change(request):
current_user = request.user
form = UserProfileChange(instance = current_user)
if request.method == 'POST':
form = UserProfileChange(request.POST,instance = current_user)
if form.is_valid():
form.save()
form = UserProfileChange(instance = current_user)
form = UserProfileChange(instance = current_user)
return render(request, 'App_Login/change_profile.html', context={'form':form})
#login_required
def pass_change(request):
current_user = request.user
form = PasswordChangeForm(current_user)
if request.method == 'POST':
form = PasswordChangeForm(current_user, data = request.POST)
if form.is_valid():
form.save()
return render(request, 'App_login/pass_change.html', context = {'form':form})
here is urls.py file
from django.urls import path
from . import views
app_name = 'App_Login'
urlpatterns = [
path('signup/', views.signup, name = "signup"),
path('signin/', views.login_page, name = 'signin'),
path('logout/' , views.logout_user, name = "logout" ),
path('profile/' , views.profile, name = "profile" ),
path('change-profile/' , views.user_change, name = "user_change" ),
path('password/' , views.pass_change, name = "pass_change" ),
]
here is change_profile.html
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block title %} change User profile {% endblock %}
{% block body_block %}
<h2>Change Profile</h2>
<form method="post">
{% csrf_token %}
{{form|crispy}}
<input type="submit" value="Change" class = "btn btn-primary btn-sm">
</form>
{% endblock %}
here is forms.py file
from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from django.contrib.auth.models import User
class SignupForm(UserCreationForm):
email = forms.EmailField(label = "Email Address", required=True)
class Meta:
model = User
fields = ('username','email', 'password1', 'password2')
class UserProfileChange(UserChangeForm):
class Meta:
model = User
fields = ('username','email','first_name', 'last_name', 'password')

Django has an inbuilt functionality to do that in your urls file modify it to according your needs
from django.contrib.auth import views as auth_views
urlpatterns = [
#
# Rest Of Your Code
#
path('password/',auth_views.PasswordChangeView.as_view(
template_name='template to render here',
success_url = 'page to redirect after password is changed'),name='password')

Unable to show user specific link to specific page in django

I would like to create user specific links. I mean, when user signed up and logged in, he has redirected to create/ page. In that page user fills out the form and after pressing button, user has to redirect to list/ page, where there are user specific links to specific page, which contain schedule. Schedul appered from data, which user provided in create/ form.
So my problem is, when I filled out the form and redirect to list/ page, there are no links.
My code:
models.py
from django.db import models
from django.contrib.auth.models import User
class File(models.Model):
file = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
#Further, they are fileds, which is nececary to create schedule.
#title = models.CharField('Название Графика', max_length = 50)
#x_title = models.CharField('Название Оси Х', max_length = 50)
#y_title = models.CharField('Название Оси Y', max_length = 50)
#etc...
views.py:
def create(request):
error = ''
if request.method == 'POST':
form = FileForm(request.POST)
if form.is_valid():
form.save()
return redirect('grafic:list')
else:
error = 'Форма была неверной('
form = FileForm()
data = {
'form': form,
'error': error,
}
return render(request, 'graf/create.html', data)
def list(request):
qs = File.objects.filter(file=request.user)
context = {
'user': request.user,
'qs': qs,
}
return render(request, 'graf/list.html', context)
list.html
{% extends 'base.html' %}
{% block content %}
{% if user.is_authenticated %}
<h2>{% block title %} Profile {% endblock %}</h2>
<p>Username: {{ user }}</p>
{% for b in qs %}
<article class="card">
<div class="card_wrapper">
<figure class="card_feature">
</figure>
<div class="card_box">
<a href="{% url 'grafic:index' b.id %}">
<header class="card_item card_header">
<h6 class="card__item card__item--small card__label">Твой график</h6>
<a class="card__item card__item--small card__title" href="{% url 'grafic:index' b.id %}">
{{b.graf_title}}
</a>
</header>
<hr class="card__item card__divider">
</a>
</div>
</div>
</article>
{% endfor %}
{% endif %}
{% endblock %}
urls.py
from django.urls import path
from . import views
app_name = 'grafic'
urlpatterns = [
path('', views.first, name = 'first'),
path('create/', views.main, name = 'main'),
path('list/', views.list, name = 'list'),

That's all. Sorry if my code is such inconvenient. Thank you in advance for your cooperation)

That is my problem. In the 'file' field there are no user.

Clicking on submit at billing address form redirects me at login, instead of redirecting me to shipping address form

I am following a tutorial explainig how to build an eCommerce app with django.
I have a cart section [s1] where the customer can see the resume of the products he/she has in the cart.
Here the customer can click on a "checkout" button that, according to the tutorial,
if the customer is logged in:
should lead him/her to a shipping address section [s2] where he/she can fill the shipping address form.
else:
should lead him/her to a guest authentication section [s2-b] where he/she can continue as guest (the customer is requested to submit his/her email address) or login (the customer is requested to submit user and password) and then reaches the shipping address form section [s2].
Then the app should lead the customer to a billing address form [s3] and then to a finalizing section [s4].
My problem is that I can't go past the shipping address section [s3], because as I click on the submit button, the app redirects me to the login form, (this happens even if I am already logged in) where the message "This field is required" appears for both user and password files, and as I type those in and press Submit button, the app returns me back to the home page. So I can never reach billing address form [s4].
I don't understand what is wrong, here is my code:

SOLVED
There was a very simple error in python_ecommerce/urls.py:
In urlspattern I named checkout_address_create_view the view checkout_address_create_view, while in the template I call it as checkout_address_create, so the template could not find the function and don't know why was bringing me back to login form.
I substituted
path('checkout/address/create/', checkout_address_create_view, name='checkout_address_create_view'),
with
path('checkout/address/create/', checkout_address_create_view, name='checkout_address_create_view'),
and this solved that error.

uploading images through form.py

if i upload the image through my admin dashboard, the image will be successfully uploaded, it will appear in media folder in my project directory i specified in settings.py. but if i upload an image through form.py as a user, every other field is saved except for the image field. I've tried most of the solutions on stackoverflow, dont know why mine ain't working.
while debugging i made mainimage a required field, so it threw this error: ValueError: The view products.views.products didn't return an HttpResponse object. It returned None instead.

ok better change your view to
if request.method == 'POST':
form = ProductForm(request.POST or None, request.FILES or None)
if form.is_valid():
instance = form.save(commit=False)
instance.name = form.cleaned_data['name']
instance.mainimage = form.cleaned_data['mainimage']
instance.category = form.cleaned_data['category']
instance.preview_text = form.cleaned_data['preview_text']
instance.detail_text = form.cleaned_data.get['detail_text']
instance.price = form.cleaned_data['price']
instance.Quantity = form.cleaned_data['Quantity']
instance.save()

Is your MEDIA_DIR set in your settings.py?
MEDIA_DIR = os.path.join(BASE_DIR, '/static/media/')

ValueError: The view products.views.products didn't return an HttpResponse object. It returned None instead. Means your somewhere in your views you are not returning an Http response. Try indenting last line of your view to at same level as else. It may resolve

can not upload the images

why I can not upload the images??

when I click in http://127.0.0.1:8000/things/another-things/edit/ is ok
however when I click the Edit images link to submit upload images it said no file has been choice?? I can not upload the images

You have to check the file permissions of
edit_thing_uploads.html
, make sure the file is accessible. because the path has been correct. and Django can't see it.

I got to know why ,,because I typos <form role="form" action="" method="post" enctype="multipart/form-data"> ---> <form role="form" action="" method="post" enctype="multipart/form\-data"> in edit_thing_uploads.html
