Why Django does not be deployed easily?
I have been learning Django for a long time, and I always find difficulties in deploying my projects, I often deploy my projects on AWS, and it takes a lot of money, also, the other platforms take a lot of fees to make your Django project deployed on their platforms, After that I decided to move to PHP here I found a difference, -and the difference is in the amount of time, that you need to deploy your project (which is a lot shorter than Django), -and the amount of fees that you need to pay to the platform to deploy your project on (it is 100%100 cheaper than Django), -and there are a lot of platforms for PHP, while Django there are few platforms to deploy your project on, -and PHP is much easier to deploy, there are platforms that just you take your project and drag it then drop it to them, and this is everything. my questions are : 1- Why sometimes you have to take a cloud computer service then you have to install python , and everything in python , then you upload the Django project, it is like you are using it on your … -
TinyMCE style working in Django admin, but not working in Angular frontend
I have django backend admin template, with TinyMCE textfield. In the textfield I add inline CSS style to the HTML. It's working correctly. <ol style="color: blue; font-weight: bold;"> <li><span style="color: black; font-weight: normal;">L&aacute;togasson el a szolg&aacute;ltat&oacute; oldal&aacute;ra: </span></li> <li><span style="color: black; font-weight: normal;">Adja meg a regisztr&aacute;ci&oacute;hoz sz&uuml;ks&eacute;ges adatokat (a partnersz&aacute;mot &eacute;s a sz&aacute;ml&aacute;n szereplő nevet kiemelt&uuml;k).</span></li> <li><span style="color: black; font-weight: normal;">Jegyezze fel a regisztr&aacute;ci&oacute; sor&aacute;n megadott e-mail c&iacute;met &eacute;s jelsz&oacute;t (k&eacute;sőbb sz&uuml;ks&eacute;g lesz r&aacute;).</span></li> <li><span style="color: black; font-weight: normal;">Sikeres vagy sikertelen regisztr&aacute;ci&oacute; ut&aacute;n kattintson a Tov&aacute;bb gombra.</span></li> </ol> But on the frontend (with innerHTML), the styling is not working.

Design User class in Django
I use the AbstractUser class to extend my User class. In my User class, there are currently 3 roles: Admin, Lecturer and Alumni. I can use is_superuser, is_staff to solve the problem, however, in the future there may be more roles appearing and if I use the above method it will not be possible to add more roles better. But if I use the additional field role = models.IntegerField(choices=Role.choices, default=Role.ALUMNI) it looks fine. But when using superuser, is_superuser = True and the user's role is Alumni. By the way, I'm working on a project using django, rest_framework. I want Users with the role of Lecturer to be created by the Admin and set a default password, and after 24 hours from the time of account creation, if the Lecturer does not change the password, the account will be locked and the Admin will have to reopen for Lecturer. I wrote two functions save and check_password_expiry but I'm not sure if it works as I want. Can someone solve my current problem, please? class User(AbstractUser): class Role(models.IntegerChoices): ADMIN = 1, "Admin" LECTURER = 2, "Lecturer" ALUMNI = 3, "Alumni" avatar = CloudinaryField(null=True) cover = CloudinaryField(null=True) role = models.IntegerField(choices=Role.choices, default=Role.ALUMNI) alumni = … -
How can we get custom token from dj-rest-auth while authentication?
We are trying to use dj_rest_auth to make social authentication, starting with Google auth, work on a site / app using JWT token pair (access & refresh). Our attempted solution is as follows: Goal: We are modifying the register & login API endpoints provided by dj_rest_auth to return our JWT custom token pair (as returned by the api/token endpoint), instead of the session key. Possible options: Option 1: Extend dj_rest_auth.registration.views.RegisterView with a CustomRegisterView, modifying the perform_create method to return the JWT token pair. Option 2: Let dj_rest_auth.registration.views.RegisterView return the session key & token be in the cookie, but modify the token in the cookie to add the logic in our custom token serializer to add additional fields. The above approaches will apply to Loginview as well. Our questions: Which of the above is better? Our preference is for approach 1 - more consistent with our maintenance & use of tokens before social auth. Is there any concern with the above option 1 - ie having register & login endpoints return the JWT token pair? Assuming Option 1 - what is the best way to do it? We are trying to extend the RegisterView - but it’s unclear which method to … -
Is there a boilerplate template for a TDD approach in Django-Python

Why does Sentry catch my local host errors but not my errors for my prod url in Django?

Flask as a back-end web programming framework
I'm currently working on a simple project that I wanted it to be my introduction to python web programming. I've wrote a python code of what I needed and I'm working on the interface that I wanted to be a web based one. I choose to work with flask. I wanted to know whether I have to modify the code to be suitable with the framework? and how to manipulate the database since I was working with csv files in my initial code? So basically the code consists of different search algorithms in artificial intelligence (BFS, DFS, A* and hill climbing) that return a path in a map. I wanted to used html, css, js and flask to implement an interface that gives the user option to choose starting and goal states and represent that resulting path in a map. -
Adding the django-parler to admin page in Django admin
I'm working on my Django project and I added django-parler to my Django project. I have added parler in my models.py and that looks like this: class Category(TranslatableModel): translations = TranslatedFields( category_name=models.CharField(max_length=255, verbose_name="Category name"), ) parent = models.ForeignKey('self', null=True, blank=True, on_delete=models.CASCADE) slug = models.SlugField(max_length=200, unique=True, editable=False, default='') def clean(self): if self.parent: if self.parent.parent: raise ValidationError("A category that already has a parent cannot be set as the parent of another category.") def save(self, *args, **kwargs): if not self.slug: base_slug = slugify(self.safe_translation_getter('category_name', self.category_name)) # Ensure uniqueness of the slug slug = base_slug counter = 1 while Category.objects.filter(slug=slug).exists(): slug = f"{base_slug}-{counter}" counter += 1 self.slug = slug super(Category, self).save(*args, **kwargs) class Meta: verbose_name = "Category" verbose_name_plural = "Categories" ordering = ['category_name'] def __str__(self): return self.safe_translation_getter('category_name', self.category_name) Tricky part is that I want slug to be translated not just category name. Also, in admin.py I did it like this: admin.site.register(Category, TranslatableAdmin) And I got it like on images below. I'm happy with the result. What you see on first image, is when you click on categories on admin side, and if I have multiple translations it makes entry for every language. On second image you see how it looks like when you are adding … -
How to Prefetch a group concat field in Django
my question is the following : I have a view table mapped to the Django ORM, with a group_concat field using MariaDB. Is it possible to fetch IDs from this: This view stores data for operators, and each operator can be associated with multiple companies Class OperatorsView(models.Model): id = models.IntegerField(primary_key=True, db_index=True) # fleet_operator_id fleet_operator = models.ForeignKey( "companies.FleetOperator", on_delete=models.DO_NOTHING, null=True ) user = models.ForeignKey( "accounts.MobileUser", on_delete=models.DO_NOTHING, null=True ) operator = models.ForeignKey( "companies.Operator", on_delete=models.DO_NOTHING, null=True ) companies_shared_str = models.CharField( db_column="companies_shared_id", null=True, max_length=4000 ) So I would like to know if the companies_shared_str field is possible to be used in OperatorsView to prefetch in advance, not using a @property because this will lead to N + 1 queries. Any suggestions would be greatly appreciated -

forbidden (403) CSRF was not verified. The request was cancelled
I am logogin with super admin in django project and want to change some properties of users but when i clicked at save button it shows an error as below: forbidden (403) CSRF was not verified. The request was cancelled. Help Reason given for failure: Origin checking failed - https://somedomain.com does not match any trusted origins. In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. The view function passes a request to the template’s render method. In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL. If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data. The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.

Django static files 404 errors just for one folder and all images

Django crispy-form, data from the form is not saved in the database
I'm just starting my adventure with Django. I wrote a small application in which, of course, there is a form that collects data from the user. This form in the standard version of Django doesn't look nice. I found information about crispy-form on the Internet and added it to my project. I managed to create a form that I like, but there is a problem. I cannot save the data retrieved from the form to the database. Previously, when I had a Django form, in the views.py file, the function handling this form saved the retrieved data to the database. Now that it's crispy-form I don't want to save. My knowledge is too little to be able to do it, hence my request to you for help. Can you take a look at the codes below and tell me what I'm doing wrong? forms.py from django.forms import ModelForm from crispy_forms.helper import FormHelper from .models import Firma, DaneKsiegowe from django import forms from django.urls import reverse from crispy_forms.bootstrap import Field, TabHolder, Tab from crispy_forms.helper import FormHelper from crispy_forms.layout import Submit, Layout, Fieldset class FormNowaFirma(forms.Form): nazwa = forms.CharField(required=True, max_length=120) typ_ksiegowosc = forms.ChoiceField( choices=(("ryczałt ewidencjonowany","ryczałt ewidencjonowany"),("ryczałt ewidencjonowany bez VAT","ryczałt ewidencjonowany bez VAT"), ("KPiR … -
RoutablePageMixin working locally but not on Heroku
I'm in the process of gradually upgrading an old Wagtail CMS website. I've just upgraded from Wagtail V2.13.5 to 2.15.6, including upgrading from Django 3.1 to 3.2, and Python from 3.8 to 3.10. The website is working 100% fine on my local dev copy (Win10), and 95% fine on my Heroku staging environment. However, the parts of the site that uses RoutablePageMixin are not working on my Heroku staging environment (Heroku-22 stack). The website is a fairly basic blog, with an index page ('/explore/') below the homepage, and I'm using RoutablePageMixin to create a 'latest' page ('/explore/latest/') to display the 5 most recent posts below that. This '/explore/' and '/explore/latest/' pages work fine locally, but on my Heroku staging environment '/explore/' is fine but '/explore/latest/' just displays a 404 error ('rasied by wagtail.core.views.serve)'.

I'm creating an app in django with custom registration and login that behave like forms, but when I log in with wrong credentials, the program returns an AssertionError. . views.py ... def post(self, request): serializer = LoginSerializer(data=request.data) if serializer.is_valid(): email = serializer.validated_data['email'] password = serializer.validated_data['password'] user = authenticate(email=email, password=password) if user: login(request, user) return redirect('/') else: return Response({'erro': 'user nao encontrado'}) serializers.py class LoginSerializer(serializers.ModelSerializer): email = serializers.EmailField(required=True) password = serializers.CharField(write_only=True, style={'input_type': 'password'}) class Meta: model = Profile fields = ['email', 'password'] def validate(self, attrs): email = attrs.get('email') password = attrs.get('password') if email and password: user = authenticate(email=email, password=password) if not user: raise serializers.ValidationError('O usuário não existe') attrs['user'] = user return attrs I've already tried a try and except, as well as adding a Response if the user doesn't exist, but still, nothing works.
