Python & Django web app - auto emails not sending - troubleshooting Cron
I have a webapp running on an ubunti vps. Cron is scheduled to run a task evry sunday morning, however, I found it ran once and not again the next week. I have been reading about cron and how to troubleshoot but need help understanding what is shown when I run sudo systemctl status cron. Please describe what the lines below are telling me.

Webapp in pure Pyton resp. without JS?
I search a Language and / or Framework to develop a professional Webapp in (for example) pure Python. My prefered language is python, but i could also use somethin other. The point is, that I don't want to use JavaScript, because i probably hate that shit. (sorry for that statement). I was flirting with Django and recently read about Reflex. But I'm not sure if I can develop a really stunning frontend with Django (without a JS framework) and Reflex perhaps seems to be a bit immature (I'm not sure about this...). So the goal is to develop a whole Webapp (but more or less small and simple) without using JS, and ideally with python. Since i perhaps wanna do some numerical calculations or data science stuff in the backend / background, i think python would be easy and straight forward. Constraints: I don't want to use the Microsoft dotnet stuff. It's important, that i can use nearly any database in the background. Perhaps I wanna use a Graph-Database at the end. But i'ts open now. (... open arch, freedom to choose...) Optional: I could also use some other langauge? (sic!) It should be fully OpenSource to use, perhaps with … -
Unable to create UserProfile object for User
I have a User model and a UserProfile model with a one-to-one relationship. I'm using a serializer to create users, and I want to automatically create a corresponding UserProfile object for each user upon creation. However, I'm encountering an issue where the UserProfile object is not getting created when I create a new user. Despite setting up the UserProfile model with a OneToOneField relationship to the User model and specifying the related name as "userprofile", I keep getting an error stating that there is no related object. Additionally, when I retrieve user data using the GET method with this serializer, the userprofile field shows as null, even though I expect it to contain the related UserProfile object. Here's my UserSerializer: class UserSerializer(serializers.ModelSerializer): userprofile = UserProfileSerializer(read_only=True) profile_data = serializers.JSONField(write_only=True) class Meta: model = account_models.User fields = ( "id", "username", "password", "email", "is_premium", "premium_time", "userprofile", "profile_data" ) extra_kwargs = { "password": {"write_only": True}, } def create(self, validated_data): profile_data = validated_data.pop('profile_data') image_path = profile_data.pop("image_path", None) password = validated_data.pop("password") user = account_models.User.objects.create(**validated_data) user.set_password(password) user.save() userprofile = profile_models.UserProfile.objects.create(user=user, **profile_data) if image_path: save_image(instance=userprofile, image_path=image_path) send_notification(user=user, action="CREATE_ACCOUNT") return user And here's the relevant part of my UserProfile model: class UserProfile(models.Model): def image_path(self, filename): return f"Users/user_{self.user.id}/{filename}" user = … -

How to send confirmation emails and scheduled emails in Django
I'm working on a Django project involving a custom user registration form. My goal is to implement a two-step email notification process upon form submission: Immediate Email Confirmation: Automatically send a customized email to the user immediately after they submit the form. Scheduled Email Notification: Send a second customized email at a later date, which is determined by the information provided when the form is created (e.g., a specific date for event reminders). The scheduling of the second email needs to be dynamic, allowing for different dates based on the form's context, such as varying event dates. How can I achieve this with Django? especially for scheduling emails to be dispatched at a future date. Note that I expect a volume of 1000 submissions per month. Thanks for your help in advance. -

What is the best approach for class inheritance and custom view tracking in Django?
I'm trying to figure out how to properly use class inheritance in Django. One thing I'm struggling with is making a custom view that keeps track of what users are doing. The main thing I'm stuck on is the class I made: class Tracker: activity = None def action(self, *login_user: User, whom: User, is_current: bool) -> None: """Create Action model""" ... def visitor(self, login_user: User, whom: User) -> None: """create a Visitor model""" ... @validate_view_inheritance def tracker(self, login_user: User, whom: User): url_user = self.kwargs.get("username") login_user: User = self.request.user is_current_user = login_user.username == url_user self.action(login_user=login_user, whom=whom, is_current=is_current_user) self.visitor(whom, login_user) You can noticed that I'm trying to get info about request and kward, but they're not part of the class itself. It seems to work only when I inherit this class with certain Views. Is this the right way to do it? Additionally, I use a custom decorator that checks if this class is a subclass of View. If not, it raises an ImproperlyConfigured error. In the future, I want to use this class to make custom views like this: class CustomDetailView(DetailView, EpulsTracker): activity = ActionType.PROFILE def get(self, request, *args, **kwargs): """Overrides the get method.""" self.object = self.get_object() context = self.get_context_data(object=self.object) # … -

Trouble with Django Authentication: Instead of showing templates it show admin page
I'm currently learning Django authentication and have encountered an issue with customizing HTML templates. Instead of displaying my custom templates, Django redirects me to the admin dashboard. For instance, when I modify LOGOUT_REDIRECT_URL to logout and name in TemplateView to logout, I expect to see my custom logout page located at templates/registration/logout.html. However, Django continues to redirect me to the default admin dashboard logout page. But when i set both to customlogout then it directs me correctly. Similarly, I face a problem with the "Forgotten your password?" button. When clicking on it, I anticipate being directed to templates/registration/password_reset_form.html, but instead, I'm redirected to the Django admin dashboard. Below is my code setup: settings.py: LOGIN_REDIRECT_URL = 'home' LOGOUT_REDIRECT_URL = "customlogout" app urls.py: from django.urls import path from django.views.generic import TemplateView urlpatterns = [ path('', TemplateView.as_view(template_name='home.html'), name='home'), path('logout/', TemplateView.as_view(template_name='logout.html'), name='customlogout'), ] project urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('account.urls')), path("accounts/", include("django.contrib.auth.urls")), ] Password reset template templates/registration/password_reset_form.html: <h1>Password Reset</h1> <p>Enter your email ID to reset the password</p> <form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Reset</button> </form> -
Template code not showing in Django template file despite moving from base.html to sports.html
I have a Django project where I initially wrote all the HTML and template code in the base.html file. However, as my project grew, I decided to organize my templates better by moving specific code to separate template files. I created a new template file named sports.html and copied the relevant code from base.html to sports.html. However, when I view the sports.html page in my browser, I only see the contents of base.html being rendered, and the code I moved to sports.html is not showing up. Here's the structure of my sports.html file: {% extends 'BTXApp/base.html' %} {% block content %} <!-- My content code goes here --> <!-- But it's not showing up in the rendered page --> {% endblock %} I have double-checked the paths and the configuration in my Django settings, and everything seems to be correct. I can see the code perfectly fine in my text editor (Sublime Text), but it's not rendering in the browser. What could be causing this issue, and how can I resolve it? Any help or insights would be greatly appreciated. Thank you! -

Can I Register a Django Project's Inner Directory as an App Within the Same Project?
Within a Django project, such as "myproject," where a subdirectory named "myproject" is automatically created, I've registered this subdirectory as an app with the intention of using it as a control app for the entire project. For instance, if my project directory structure looks like this: myproject/ ├── myproject/ │ ├── __init__.py │ ├── settings.py │ ├── urls.py │ ├── apps.py <!-- the odd addition --> │ ├── wsgi.py │ └── asgi.py ├── myapp1/ │ ├── __init__.py │ ├── models.py │ ├── views.py │ └── ... └── ... I've registered the inner "myproject" directory as an app within the Django project. Despite this setup functioning smoothly, I'm curious about the community's thoughts or any considerations regarding this approach. Are there any insights, opinions, or best practices associated with registering the project directory as an app within a Django project? -

But when the user selects one of the options, the .hide() won't work. The in-line style of style="display: block;" doesn't change when I do $('#dropdownListContainer').hide(); I have tried many things such as: making sure its wrapped in a $(document).ready(function(), checking if js recognizes its display is block (which it is as the console.log("okokoko"); prints as seen in my code below), I make sure my jquery is loaded before my js file, I tried using vanilla js instead, but none of those have worked, and I don't understand why the .show() would work but not the .hide(). Any help would be appreciated. Thank you. js: $('#ratingDropdownContainer').on('click', function() { if ($('.dropdown-list-container').css('display') == 'none') { $('.dropdown-list-container').show(); } }) $('.avg-rating-select').on('click', function() { var selectedRatingImg = $(this).find('img').prop('outerHTML'); var selectedRatingText = $(this).find('p').prop('outerHTML'); var newDiv = $("<div>" + selectedRatingImg + selectedRatingText + "</div>"); newDiv.addClass("rating-selected-container"); if ($('.rating-selected-container').length) { $('.rating-selected-container').replaceWith(newDiv); } else … -
Django modeltranslation not working properly on templates
I have set up and configured django-modeltranslation for a project according to the documentation as follows: urls.py from django.conf.urls.i18n import set_language from django.conf.urls.i18n import i18n_patterns urlpatterns = i18n_patterns( ... path('set_language/', set_language, name='set_language'), ) settings.py from django.utils.translation import gettext_lazy as _ INSTALLED_APPS = [ 'modeltranslation', ... ] MIDDLEWARE = [ ... 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', ... ] TIME_ZONE = 'CET' LANGUAGE_CODE = 'en' LANGUAGES = [ ('en', _('English')), ('cz', _('Czech')), ] LOCALE_PATHS = [ BASE_DIR / 'Project/locale/', ] USE_I18N = True Homepage language switcher <form id="languageForm" action="{% url 'set_language' %}" method="post"> {% csrf_token %} <input name="next" type="hidden" value="{{ request.get_full_path|slice:'3:' }}" /> <input id="languageInput" name="language" type="hidden" value="" /> </form> onclick="setLanguage('en')" onclick="setLanguage('cz')" function setLanguage(lang) { document.getElementById('languageInput').value = lang; document.getElementById('languageForm').submit(); } In .html templates {% load i18n %} ... {% trans "Text" %} ... I collected the strings for translation using: python manage.py makemessages -l cz Then translated them in the locale django.po file and compiled them using: python manage.py compilemessages Now when running the project and switching the language to cz, only one translated string and date strings are displayed. Thank you for your help, and I hope I provided everything needed. I tried setting up the django-modeltranslation using its documentation as I provided before. -

Django: Redirect to object's change (admin) page while overriding save_related
I am uploading a temporary file while changin my object, and this file might have problems which I can determine after it is fully read. I want my page to be rediretded to the object's change page whenever an error occures. here's the code i wrote: def save_related(self, request, form, formsets, change): try: cleaned_data = form.cleaned_data if cleaned_data['file_field']: DEFAULT_COLUMN_INDEX = 0 try: # read file logic here that might raise an error return super().save_related(request, form, formsets, change) except ValidationError as e: messages.error(request, f"Error while proccessing data: {str(e)}") redirection_url = reverse('admin:mymodel_change', args=[form.instance.id]) return HttpResponseRedirect(redirection_url) except TimeoutError as e: messages.error(request, f"Timeout in uploading file: {str(e)}") redirection_url = reverse('admin:mymodel_change', args=[form.instance.id]) return HttpResponseRedirect(redirection_url) Note that i can not just raise the error because it is set to response 500 because of other parts of the project (long story... i just cant change them!) Here's my problem: This code redirects to the mymodel admin page, not the change page of the object. So, here's my questions: Am i doing the right approach (since I'm new to django)? If the approach's fine, how can i fix it? -
