Django - customized password validator - error in path to my validators.py
I want to add my own password validator in my django project 'MyProject' so I create a validators.py file in my registration app but don't know how to set in my settings? settings.py AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, { 'NAME': 'MyProject.registration.MyValidator', }, ] validators.py from django.core.exceptions import ValidationError from django.utils.translation import gettext as _ class MyValidator: def __init__(self): def validate(self, password, user=None): if password == 'banane': raise ValidationError( _("This password must contain at least 2 special characters."), code='invalid_password', params={}, ) def get_help_text(self): return _( "Your password must contain at least 2 special characters." ) -
REMOTE_USER is empty in the django after redirecting
It seems to me that I do not quite understand the REMOTE_USER variable. I have three instances based on different hosts: nginx, django_auth_server, django_app_server. I am trying to implement "single sign on": the user logs on to the django_auth_server via nginx, is redirected to the django_app_server and continues surfing without authentication. In my case after redirection to the root folder (from '/login' to '/') the REMOTE_USER variable is empty. But it does exists in the request headers: Content-Type: text/html; charset=utf-8 Location: / REMOTE_USER: alfabeta X-Frame-Options: SAMEORIGIN Vary: Cookie Content-Length: 0 Set-Cookie: csrftoken=... Set-Cookie: sessionid=... Code from the authorization view (djangoauth instance): if user is not None: login(request, user) r = redirect('/') r['REMOTE_USER'] = username return r I'm not sure if it is correct to set the variable in this way. part of the nginx config server { listen 8080 default_server; server_name localhost; charset utf8; autoindex off; underscores_in_headers on; proxy_pass_request_headers on; ... location / { include /etc/nginx/uwsgi_params; uwsgi_pass uwsgiapp; uwsgi_read_timeout 300; uwsgi_param Host $host; uwsgi_param X-Real-IP $remote_addr; uwsgi_param X-Forwarded-For $proxy_add_x_forwarded_for; uwsgi_param X-Forwarded-Proto $http_x_forwarded_proto; } location =/login/ { include /etc/nginx/uwsgi_params; uwsgi_pass uwsgiauth; uwsgi_read_timeout 300; uwsgi_param Host $host; uwsgi_param X-Real-IP $remote_addr; uwsgi_param X-Forwarded-For $proxy_add_x_forwarded_for; uwsgi_param X-Forwarded-Proto $http_x_forwarded_proto; uwsgi_param REMOTE_USER $remote_user; } How to … -
Formset using class-based views with multiple instance
I want to use formset to add multiple todo at once, I have been told to use formset, which is exaclty what I am looking for, but all the documentations and video tutorials are using function based view. I have my models.py class Todo(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE,verbose_name="Nom de l'utilisateur") text = models.CharField(max_length=150, verbose_name="Nom de la Todo") content = models.TextField(verbose_name="Description supplémentaire",null=True, blank=True) date_posted = models.DateTimeField(default=timezone.now) complete = models.BooleanField(default=False, verbose_name="Statut de la Todo") urgence = models.BooleanField(default=False,verbose_name="Tâche urgente") def __str__(self): return self.text def get_absolute_url(self): return reverse('dashboard-home') To me, that should be enough because i have author as foreignkey, of course I import formset_factory at the top. But then it's very not clear for the view Views.py class TodoCreateView(SuccessMessageMixin, LoginRequiredMixin, CreateView): model = Todo fields = ['text','urgence'] success_message = 'Votre tâche a bien été ajoutée' def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) How everything should work ? The purpose of this is just to add multiple todo at once, nothing too difficult, but I struggle. Just an example : This, but with multiple input. Thanks for your help -

I'm trying to add the klarna javascript SDK into my site in which I need the client_token.and also created the test environment where I got the API key inside this have got the username and password for my test merchant account.

Is it necessary to create the session to integrate the klarna payment gateway in django oscar ? How can we use the test account credential for creating the session and client_secret A Mockup example to get me started in the right direction will be helpful. -

language independent query with django-modeltranslation
I currently started to use django-modeltranslation in a Django app and I would like to make a query to retrieve the instance of a model, independent of the language set in the system. For example I have the following model: class Product(models.Model): description = models.CharField(max_length=200) sku = models.CharField(unique=True, null=False, max_length=30) price = models.DecimalField(max_digits=8, decimal_places=2) and the following in translation.py: class ProductTranslationOptions(TranslationOptions): fields = ('description', 'sku') translator.register(Product, ProductTranslationOptions) and the Django setting: gettext = lambda s: s LANGUAGES = ( ('en', gettext('English')), ('de', gettext('German')), ) MODELTRANSLATION_LANGUAGES = ('en', 'de') MODELTRANSLATION_DEFAULT_LANGUAGE = 'en' MODELTRANSLATION_FALLBACK_LANGUAGES = ('en',) Let's create a product instance: Product.objects.create(description_en='product en', description_de='product de', sku_en='sku-001', sku_de='sku-002', price=10.0) Now I want to find the instance with the sku sku-002, to retrieve the price of a product (which is independent of the language). Product.objects.filter(sku='sku-002') However this returns an empty MultilingualQuerySet. Only the following returns the correct Product instance. Product.objects.filter(sku_de='sku-002') or from django.utils import translation translation.activate('de') Product.objects.filter(sku='sku-002') I guess this is the intended behavior of django-modeltranslation, but sometimes it would be practical to find an instance independent of the language. A solution could be to iterate through all LANGUAGES and try to find the instance for each language: from django.conf import settings LANGUAGES = … -
Handle .envs in docker and gitlab ci without having it in the repository
I am running a dockerized django app that uses Gitlab CI for automated tests. In my .env/ folder I have a .local and a .production file that contains my environment variables that are read in my setup-file with env = environ.Env() env(...). I think that is pretty standard. Up until now my .env/local file was committed in my repository and the tests need it to run because in my docker compose file I have: env_file: - ./.envs/.local/.django - ./.envs/.local/.postgres and I run my tests in gitlab CI using docker-compose -f local.yml run django pytest. Now I do not want my local env file in my repository. Simply because it is bad practice and I would also like to store some secret keys like AWS etc in there. But then it breaks my tests. Is there any recommended way on how to achieve what I want? Or is that not possible? I tried to add another .secret file, but also this one I have to specify in my compose file. This seems to be related How do I add a .env file in gitlab ci during deployment stage? but there is nothing on how to do this with django, docker and … -

Django how to annotate manytomany field with count
Considger the following: class ModelA(models.Model): pass class ModelB(models.Model): model_as = models.ManyToManyField(ModelA, db_index=True, related_name="model_bs", blank=True) model_bs = model_a_object.model_bs.all() for model_b in model_bs: print(model_b.model_as.count()) 3 2 So far so good. But I want to created an ordered list of model_bs depending on the count of model_as. My understanding is that simply this should do the trick: model_bs = model_a_object.model_bs.all().annotate(count=Count("model_as")).order_by('count') For some reason that doesn't work. When I print to check, the annotated count is wrong!! for model_b in model_bs: print(model_b.model_as.count(), model_b.count) 3 1 2 1 What did I do wrong? -

Django ModelAdmin: how to ask password using two secret fields?
This is my custom user model: class CustomUser(AbstractUser): created = models.DateTimeField(auto_now_add=True) username = models.CharField(max_length=100, unique=True) email = models.EmailField(max_length=200, unique=True) company = models.ForeignKey(Company, on_delete=models.CASCADE, related_name='%(class)s_company') Since there is a foreign key field, I have created a custom ModelAdmin: class CustomUserAdmin(admin.ModelAdmin): exclude = ('groups', 'user_permissions', 'date_joined') list_display = ('username', 'email', 'company') Otherwise it works fine, but there is only one, clear-text password field shown. How can I modify it so that Django Admin would ask the password using the default two field approach? -
Djongo issue with "id" field and existing mongo db
I'm trying to use django+djongo and an already existing mondo database. The collection I need to read is like this: { "_id" : ObjectId("5dde69143f664504b7149fed"), "name" : "example_123456", "hash" : { "md5" : "d9feb4e791077aeba4e946696a2fbf8a", "sha256" : "72f7a877db57e43580495d0ac05615138a73e3f8507781188d4469b1bf09389b", "sha1" : "38e600408e141389d0bb0baaf6a2e0594411a34d" }, } So in my models.py I've created these two models: class Hash(models.Model): md5 = models.TextField() sha256 = models.TextField() sha1 = models.TextField() class Meta: db_table = "hash" abstract = True class ExampleCollection(models.Model): name = models.TextField() hash = models.EmbeddedModelField( model_container=Hash ) class Meta: db_table = "example_collection" Now the problem is that when I try to read something from this collection (for example even a ExampleCollection.objects.all()), I get a MigrationError: Exception Type: MigrationError Exception Value: id I've noticed (by creating a "test" model) that django/djongo automatically add an "id" field in my models (that acts as a primary key), but since it doesn't exist in this collection, I get this exception. -

Python - Create multiple user types and email as the username field in Django 2
I'm working on a project using Python(3.7) and Django(2.2) in which I have to implement multiple types of users as: Personal Account - below 18 Personal Account - above 18 Parent Account Coach Account Admin along with that, I also need to use email as the username field for login/authentication.

Start 'python manage.py runserver' of django within jupyter notebook
I would like to create small application in Django. However, main requirement for this application is to be started within jupyter notebook, as every user will have such application locally. Plotly dash (from which I would like to rewrite this app) allows app.runserver() inside jupyter cell, which afterwards starts the app. However this is not available for django in the jupyter notebook. I could do !python manage.py runserver This spawns server correctly. But this server is not 'killable' using the interrupt button inside jupyter notebook - which is important feature of this approach. Same applies for os.system or subprocess.Popen. I tried also approach from this question: Django runserver from Python script Which does not work in the jupyter notebook unfortunately. This raises zmq.error.ZMQError: Address in use Is there any other approach which I could try? -
Run specific function before executing any code in the view
I haven't worked too much with Django. Let's say I have three views. The url patterns that these views are mapped to all start with string Y. Suppose I want to run specific function X before running code that the views contain. Is there a way to run function X by adding it somewhere only once instead of adding the function call to to the beginning of each of these views separately? Would middleware be the recommended way to do this? -
