recipient_list isn't getting the email address in django
I'm having trouble with smtp email sending in django. I tried to get the email address using User model => get_email = User.objects.filter(is_admin=True).values_list('email') But when I pass it to recipient_list,it can't find the email address. Here is my views.py: from django.shortcuts import render from feedbacks.models import Feedback from django.contrib import messages from django.core.mail import send_mail from django.conf import settings from django.contrib.auth import get_user_model User = get_user_model() def feedback(request): status = Feedback.objects.all() get_email = User.objects.filter(is_admin=True).values_list('email') print(get_email) if request.method == 'POST': name = request.POST["name"] student_id = request.POST["student_id"] adviser_init = request.POST["adviser_init"] phone = request.POST["phone"] email = request.POST["email"] issues = request.POST["issues"] obj = Feedback.objects.create(name=name, student_id=student_id, adviser_init=adviser_init, phone=phone, email=email, issues=issues) obj.save() try: subject = 'Student Feedback' message = "Mail from Student ID:" + student_id + "\nIssue:" + issues + "" email_from = settings.EMAIL_HOST_USER send_mail(subject, message, email_from, [get_email]) messages.success(request, 'Your issue has been sent to our admin.

Wagtail with get_full_url is redirecting to non SSL link
I am using get_full_url to get the link of pages in my wagtail application but it redirects from HTTPs to HTTP, when I changed it to get_url pr pageurl in templates, it fixed the problem and all links were redirected to HTTPs (SSL) the only problem that I faced is in the footer as it is sent in email, and it creates a server error every time I send an email with the footer bein using pageurl this is the error that I got: raise ValueError("pageurl tag expected a Page object, got %r" % page) Exception Type: ValueError at /mission/accept_plan/ Exception Value: pageurl tag expected a Page object, got '' which does not happen with get_full_url here the code in the template: <a href="{% pageurl LIBRARY %}" referrerpolicy="origin"> library is being defined in context as this library = ( Site.find_for_request(request) .root_page.get_children() .type(LibraryPage) .first() ) return { "LIBRARY": library, } when I changed to this syntaxe: <a href="{{ LIBRARY_URL }}" referrerpolicy="origin"> library = ( Site.find_for_request(request) .root_page.get_children() .type(LibraryPage) .first() ) return { "LIBRARY_URL": library.get_full_url(), } with this last syntax no server error but it redirects to https when I am on the website is there a way to fix the get_full_url to … -
Django: send confirmation email to customer AND to admins
I am sending customers a confirmation email once the Stripe webhook handler says "Okay", but would also like to send an email to the admins, so they become aware of the new order waiting to be dealt with. I added ADMINS = [("my_name", "my_email")] to my project settings and the line mail_admins(subject_admin, body_admin) to my up to that moment functioning method in the Stripe WH handler, so: from django.core.mail import send_mail, mail_admins class StripeWH_Handler: [...] def _send_confirmation_email(self, order): send_mail(subject_customer, body_customer, my_email, [customer_email]) mail_admins(subject_admin, body_admin) [...] if order_exists: self._send_confirmation_email(order) [...] But adding that line makes the method throw a server error and my webhook fails. How can I send those two emails to both customer and admin correctly? Thank you! -
Dynamically change Django form choices depending on active tab
I have a page with 4 different tabs (music genres) displaying different information depending on the tab (songs vs number of listens). At the top of the page there is a form which allows you to filter out the information on each tab (currently from/to date). I would like to add a choice field to the form, but for the choices to change dynamically depending on which tab is active. I am not sure how to go about this, or if it is possible to pass the active tab information to the web server to use as a parameter in the request. views.py: class MusicDashboard(generic.TemplateView): template_name = "support/music/dashboard.html" form_class = forms.MusicFilter def get(self, request, *args, **kwargs): self.form = self.form_class(request.GET or None) return super().get(request, *args, **kwargs) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["form"] = self.form context["jazz"] = self._dashboard_context( models.Jazz, **kwargs ) context["classical"] = self._dashboard_context( models.Classical, **kwargs ) context["rock"] = self._dashboard_context( models.Rock, **kwargs ) context["country"] = self._dashboard_context( models.Country, **kwargs ) return context def _dashboard_context(self, music_cls, **kwargs): base_qs = music_cls.objects.all() from_date = self.request.GET.get("from_date") to_date = self.request.GET.get("to_date") if from_date: base_qs = base_qs.filter(released__gte=from_date) if to_date: base_qs = base_qs.filter(released__lte=to_date) ... # Some logic here to create a table of song vs amount of times listened to … -

How do I rename image that I uploaded through Django Rest Framework
I have a problem in renaming an uploaded images. Instead of using the original name, I want my uploaded image to have the model['name'].jpg .

Django contact form: email not sending
I'm currently building a contact form for my website in Django. The only problem is that the email is not being sent when the form is submitted. This is the code: settings.py: EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' EMAIL_USE_TLS = True EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = "c******o@gmail.com" EMAIL_HOST_PASSWORD = '****' EMAIL_PORT = '587' views.py: sender_name = form.cleaned_data['nome_completo'] sender_email = form.cleaned_data['email'] message = "{0} has sent you a new message:\n\n{1}".format(sender_name, form.cleaned_data['messaggio']) send_mail('New Enquiry', message, sender_email, ['c******o@gmail.com']) My thought: Since I'm in a virtualenv, when I submit the form, the terminal displays that it was successfully submitted, and gets me back the code right, maybe the email is not sent because of that, or maybe because I'm using a gmail account? Thanks! -

How can i run a Django management command in production?
I have a Django app running on a DigitalOcean using Nginx and Gunicorn with systemd, now i added to Django a management command that should run along with the Django app and perform some action. The problem is that the management command needs to run "indefinitely" just like Django does.

Why do we need "serialize" model field attribute?

datetime.date.today() in Django (Dash app)
I have a Plotly Dash app running in Django using the django-plotly-dash package. (https://django-plotly-dash.readthedocs.io/en/latest/) The app is live here: https://www.sunfire.xyz/data/tca There is a date picker on the dashboard, and the code for the element is this: from datetime import date, datetime, timedelta html.Div([ dcc.DatePickerRange( id='date-picker-range', min_date_allowed=date(2020, 10, 21), max_date_allowed=date.today(), initial_visible_month=date.today(), start_date=date.today() - timedelta(days=7), end_date=date.today(), display_format='DD/MM/YYYY', ), ], className="plotly-datepicker"), The max_date_allowed and the default end_date should both be datetime.date.today() (which is 1st November as I'm typing this), however it seems like today() is returning the day that the django application was started. In fact, right now it's weirdly setting max_date_allowed to 31st October, but end_date is 30th Oct. If I restart the server it works correctly, and will display 1st November. How do I get date.today() to correctly display today's date when the application is running for multiple days? FYI the views.py file for this app is importing the Dash App from .dashapps import tca_log_plotter
