I have a problem with the image uploading from form (when i upload image from admin panel it works). Image just dont uploading, without any feedback and log. Help me pls
My view.py:
def class_article_create(request, URLcodenumber):
print(URLcodenumber)
if request.method == 'POST':
model = Article()
form = ArticleForm(
request.POST,
instance=model
)
print(request.method)
new_article = form.save(commit=False)
new_article.codenumber = Classes.objects.filter(
codenumber=URLcodenumber
)[0]
new_article.pub_date = date.today()
print(new_article.id)
if form.is_valid():
new_article.save()
return HttpResponseRedirect(f'/class/{URLcodenumber}')
return render(
request,
'blogpage\\create_article.html',
{
'clsName': f'Параллель {URLcodenumber}',
'codenumber': URLcodenumber,
'form': ArticleForm()
}
)
My models.py:
class Article(models.Model):
id = models.UUIDField(
primary_key=True,
default=uuid.uuid4,
editable=False
)
headline = models.CharField(
max_length=50,
default='Нет заголовка'
)
text = models.TextField(
max_length=600,
)
image = models.ImageField(

)
create_article.html

</button>
</form>
{% endblock content %}
early, there wasnt the enctype="multipart/form-data", and the problem was same
media root and url in settings.py:
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
urls.py:
from django.contrib import admin
from django.urls import path
from django.urls import re_path
from django.conf import settings
from django.conf.urls.static import static
from help_page.helppage_views import help_page
from start_page import startpage_views

name='create_class'
)
] + static(
settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT
)
proj_dir => media => images is directory for the images
Thanks for any help! :)

You need to pass both request.POST and request.FILES to the form:
from django.shortcuts import get_object_or_404
def class_article_create(request, URLcodenumber):
if request.method == 'POST':
code_number = get_object_or_404(Classes, codenumber=URLcodenumber)
form = ArticleForm(request.POST, request.FILES)
if form.is_valid():
form.instance.codenumber = code_number
form.instance.pub_date = date.today()
form.save()
return HttpResponseRedirect(f'/class/{URLcodenumber}')
else:
form = ArticleForm()
return render(
request,
'blogpage/create_article.html',
{
'clsName': f'Параллель {URLcodenumber}',
'codenumber': URLcodenumber,
'form': form,
},
)
Note: Django's DateTimeField [Django-doc]
has a auto_now_add=… parameter [Django-doc]
to work with timestamps. This will automatically assign the current datetime
when creating the object, and mark it as non-editable (editable=False), such
that it does not appear in ModelForms by default.

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')
]

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.

How can I display images in Django after uploading?

I'm making a small blog. And I will be creating a cover image uploading system.
But after uploading, I'm unable to retrieve the image.
Do you have any solutions?
Here's my model.py:
class Post(models.Model):
id = models.AutoField
author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
content_images = models.ImageField(default="media/noimg-l.jpg")
and here's form.py:
class Createcontent(forms.ModelForm):
class Meta:
model = Post
fields = (
"title",
"content",
"slug",
"content_images",
"status",
)
file = forms.FileField()
widgets = {
"content": SummernoteWidget(),
}
and this is the HTML I'm using:
<div class="row">
<form method="POST" enctype="multipart/form-data" class="post-form">{% csrf_token %} {{ form|crispy }}
<button type="submit" class="save btn btn-default">Save</button>
</form>
</div>
and my setting.py
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
X_FRAME_OPTIONS = 'SAMEORIGIN'
SUMMERNOTE_THEME = 'bs4' # Show summernote with Bootstrap4
and my views.py
ef create_post(request):
if request.method == "POST":
form = Createcontent(request.POST)
if form.is_valid():
post = form.save(commit=False)
post.author = request.user
post.published_date = timezone.now()
post.save()
return redirect('post_detail', post.slug)
else:
form = Createcontent()
return render(request, 'blog/post_creator.html', {'form': form})

Can't save ForeignKey data with Django

I'm trying to make a way to log notes associated with records. When the form is submitted, it's trying to redirect to the same url, but without the record id, which should be required to view the page. I defined it in urls with the record id, so it should be tracker/19/newnote
I want it to route to tracker/19/detail, and I'm not sure why it's routing to tracker/newnote, which doesn't exist in my urls file. Maybe I need to create it?
anyway, here are my files if anyone wants to take a crack at this with me.
