How to set up a django form field to receive data from a request?
For multilang, I store the fields in the database as json fields in this format: {"ru": "some text", "en": "some text"}, add form by itself looks like this input names example: title[ru], title[en] So i don't know how to write my form to get this data as: title: {"ru": "some", "en":"some"} What should i do? How to overwrite form field to get data like this? don’t find answers before that, I decided to completely abandon the forms and collect data with a custom function, but this decision seems to me wrong -
Google authentication MismatchingStateError in django (CSRF Warning - State not equal in request and response)
I have a problem that I have been trying to resolve for the past couple of days. When attempting to handle Google authentication in my Django web app, a MismatchingStateError is encountered at /signup/google/callback/. The issue arises when the Google authentication works correctly upon initial attempts but fails with the mentioned error after multiple tries. Even after logging in and out multiple times, the error persists. This is my first time implementing Google authentication within Django, and I've struggled to find comprehensive guidelines or resources. I'm currently learning about flow handling and recently became aware of potential associated risks. It's important to note that this problem resembles CSRF attacks. It emerges when there's a series of rapid login requests. After this error arises, subsequent logins are blocked. Notably, this issue isn't related to the session ID, as I've attempted to clear it without success. It seems tied to generation, possibly due to how states are managed. See the error here def google_auth(request): # Generate the Google OAuth authorization URL and redirect the user to it authorization_url, state = flow.authorization_url(access_type='offline', include_granted_scopes='true') request.session['oauth_state'] = state return redirect(authorization_url) def google_callback(request): # Exchange the authorization code for a Google OAuth access token. stored_state = … -
Python logging in Django : Filter won't work in logger
I have a logging custom filter class which suppose to ignore Django logs in my logger 'bucket' (I don't want to disable Django logs, just to keep them in separate log): class ExcludeDjangoLogsFilter(logging.Filter): """ Excludes django system logs from logger """ modules_to_exclude = ( "daphne.server", "django", "django.db", "django.server" ) def filter(self, record: logging.LogRecord) -> bool: """ Filters records to exclude from a logging modules with a certain names. """ return not record.name.startswith(self.modules_to_exclude) It works just fine if I pass this filter to handler but It doesn't if I pass this filter to logger. If I use this filter within logger interpreter enters the filter's class but doesn't enter in filter method. My logging config: LOGGING = { "version": 1, "disable_existing_loggers": False, # Filters: "filters": { "info_only": { "()": "logger.logger_filters.InfoOnlyFilter" }, "exclude_django_log": { "()": "logger.logger_filters.ExcludeDjangoLogsFilter" } }, # Formatters' profiles: "formatters": { "base": { "format": "[{asctime}][{levelname}][{name} / {funcName}][{lineno}] {message}", "datefmt": "%d/%m/%Y %H:%M:%S", "style": "{" }, "info": { "format": "[{asctime}][{name} / {funcName}] {message}", "datefmt": "%d/%m/%Y %H:%M:%S", "style": "{" }, "django_sys_format": { "format": "[{asctime}][{levelname} | {name}] {message}", "datefmt": "%d/%m/%Y %H:%M:%S", "style": "{" } }, # handlers: "handlers": { "important_file": { "level": "WARNING", "class": "logging.FileHandler", "formatter": "base", "filename": BASE_DIR / "logger/logs/important.log" }, "info_file": { … -

Django - two approaches to extending user model wont work together?
I am trying to make my django app require a unique email address when creating the account. When I added (the commented line in the models) the unique email constraint in the model I used to add fields before it just adds another email field instead of altering the original one. So after having found another solution with extending the AbstractUser class unfortunately Im getting 'the model User is not registered' error when im trying to make migrations. Please advice me on what would be a way to go to have both extra fields as well as unique email constraint. Heres how i have extra fields added to the user model: models class Account(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) points = models.IntegerField(default=0) #### email = models.EmailField(("email address"), blank=True, null=True, unique=True) profession = models.CharField(max_length=30, blank=True, null=True, choices =[('a', 'a'), ('b', 'b')]) def __str__(self): return self.user.username admin from django.contrib import admin from account.models import Account from django.contrib.auth.models import User from django.contrib.auth.admin import UserAdmin class AccountInline(admin.StackedInline): model = Account can_delete = False verbose_name_plural = 'Accounts' class CustomizedUserAdmin (UserAdmin): inlines = (AccountInline, ) admin.site.unregister(User) admin.site.register(User, CustomizedUserAdmin) It worked until ive added: models from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): email = models.EmailField(unique=True) settings AUTH_USER_MODEL = 'account.CustomUser' -

Alpine.js x-bind not applying after an HTMX swap
I have an element that is in the initial page load and updates after form post through an HTMX out of bounds swap. On initial load the x-bind formats as expected. After the swap the values from the swapped element display as expected using x-text. The x-bind always fails to apply the formatting that should trigger when staffCount < shiftNeed. When it should apply it quickly flickers immediately after the swap but then goes away. Same flicker is not present when it should not apply. Element on initial page load <tr x-data="{ shiftNeed: {{ day_need }} }"> <td class="fw-bold">Day</td> <td class="fw-bold text-center" x-text="shiftNeed"></td> {% for i, val in day_list|zip:day_staffing %} <td> <div id="dayCount{{ i }}" x-data="{ staffCount: {{ val }} }" x-text="staffCount" x-bind:class="{ 'bg-danger': staffCount < shiftNeed }" ></div> </td> {% endfor %} </tr> Partial template swapped in {% include "schedule/components/schedule_shift_button.html" %} <div id="{{ shift.time_of_day_label|lower }}Count{{ shift.day_num }}" class="text-center rounded" hx-swap-oob="true" x-data="{ staffCount: {{ shift.staff_count }}}" x-text="staffCount" x-init="console.log(staffCount < shiftNeed)" x-bind:class="{ 'bg-danger': staffCount < shiftNeed }" ></div> I added logging statements on the x-init to inspect output, console always displays the expected values of staffCount and shiftNeed and evaluates the criteria used in the x-bind as expected. -

Django cap a DateField value in the database
Sorry I am very new to Django. I have date of birth (DOB) as a field in my model. I use the DOB to calculate the age and get some values from other dataset. class Account(AbstractBaseUser): first_name = models.CharField(max_length=50) dob = models.DateField(blank=True, null=True) The age cannot be higher than 120 years so I raise a ValidationError with the registration and update profile forms whenever they enter a DOB of more than 120 years ago. def clean(self): cleaned_data = super(RegistrationForm, self).clean() dob = self.cleaned_data.get('dob') age = (date.today() - dob).days / 365 if age > 120: raise forms.ValidationError('Sorry but profiles cannot be registered with more than 120 years old due to scientific data unavailability.') elif age < 0: raise forms.ValidationError('Date of birth is in the future. Please enter valid birth date.') However, what if they register as born 119 years ago. In 1 or 2 years, the age would be 121 and my code will fail. Is there a way to always cap the value of the DOB in my database so the DOB is always maximum 120 years old? I checked the documentation for DateField but there is no reference to MinValueValidator as in the case of IntegerField. -

Custom Django Admin Page/View
Basically I'm trying to create a custom admin web page, like a custom a view. Ideally what I want is something where like once you log in to the admin page, there would be a link somewhere like under the list of models that would redirect you to this admin center. I have a somewhat working version currently, but I would like to have it redirect to a new URL like “ /admin/social/edit/ “ instead and not just render context into the template. I’ve done a ton of googling and I just keep coming across things like “custom admin actions” which is not per se what I’m looking to do. Any help is appreciated. Thank you. -

How can I set group permissions that filter pages according to their owners in Wagtail
I am working on a blog with Wagtail and would like to give users access to create their own content in the Wagtail admin. I would like users to be able to log into the Wagtail admin, but only have access to content that they have created themselves. I have tried to generate permissions by group, however there is no default option to limit content by author, so if I give add, edit and publish permissions, a user could edit content created by other users and could unpublish or even delete that content. I would like to know if there is a way to modify the queryset of pages that appear in the Wagtail admin for a specific user. I don't have much experience with Wagtail. So far I have seen some possible solutions but none have seemed viable or adequate. For example, there are some posts here where they propose to create a Parent page for each user, but then you would have to create a group for each user, which doesn't seem like an efficient way to do it. I appreciate any help or suggestions. Here I share some of the relevant code: class BlogIndexPage(Page): max_count = 1 … -

using mongodb with motor driver and django
i'm creating an App, using async driver(motor) for mongodb. I have a telegram bot app and django framework app. I want my telegram and web apps use same database. When i try to create User via integrated CreateView class, by default django uses it's standart auth processing and adds user to its default databases(sqlite, postgre etc.) But i'd like to use mongodb and use it asyncronous(as i understood djongo is syncronous driver) the ways I see to solve this: 1) separate users' auth data(to standart database) and other data, that'll be fetched and overwritten frequently(to mongo). 2) use standart view(e.g. TemplateView, FormView) and my own form, write MyOwnUserClass with hashing and all necessary methods. Shortly I want to use instruments of Django with mongodb, how can I reach that? Well don't know if this is needed here, a piece of my current code: forms.py: class RegisterUserForm(UserCreationForm): username = forms.CharField email = forms.EmailField password = forms.PasswordInput password_confirm = forms.PasswordInput telegram = forms.CharField(required=False) views.py: class Register(CreateView): template_name = 'AIsite/register.html' form_class = RegisterUserForm success_url = reverse_lazy('login-user')
