How to implement navigation DB data in Django?
got this code from a friend, we use django and bootstrap to make a rather simple site that displays job offers, until now we displayed the job offers in a row and each offer had a button "apply" that sent the resume etc.. But we would like to change that and only display one job at a time, each job would have 2 buttons "apply" and "next". We tried in a barbaric way to do all this but we have a problem, the next button works well thanks to a little javascript incorporated by my friend but the "apply" button we would like to move to the next offer after clicking on it, for now it only applies we can't get it to display the next offer, how to do? Thank you very much for simplifying your answers I am a beginner in web development, here is the code of my Django template: {% extends 'base2.html' %} {% load static %} {% block title %} Dashboard {% endblock %} {% block content %} <body class="hold-transition light-mode layout-fixed layout-navbar-fixed layout-footer-fixed"> <div class="wrapper" > <div class="content-wrapper" > <!-- Content Header (Page header) --> <section class="content-header"> <div class="container-fluid"> <div class="row mb-2"> <div class="col-sm-6"> … -
Inline Images are also being attached
I am using templated_email package to send emails and embedding images using the below code block. Inline images are also being added as attachments in some devices. I don't want them to added as attachments. Is there any solution? with open(path_to_img, 'rb') as image: image = image.read() inline_image = InlineImage(filename=image_name, content=image) This is the documentation of the templated_email package https://pypi.org/project/django-templated-email/#:~:text=with%20open(%27pikachu.png%27%2C%20%27rb%27)%20as%20pikachu%3A I found a solution where if we use MIMEMultipart('related') it will solve the issue if we are using MIME to embed images directly. I want to implement the same while using Django's templated_email package. -

How can I sort by calculated fields in Django Admin?
I have a calculated method in my model, and in admin page want to add sort functionality for that calculated field. For now, I am using aggregation for model calculated fields and displaying that in admin. How can I add sort function for this field in admin page? class CoinWallet(Account): student = models.OneToOneField( 'students.Student', on_delete=models.PROTECT, related_name="coinWallet", null=True) @admin.display(description='Total Coins') def total_coins(self): positive_movements_aggregate = self.movement_set.filter( side=self.positive_side, ).aggregate(models.Sum('amount')) positive_movements_balance = positive_movements_aggregate[ 'amount__sum'] if positive_movements_aggregate['amount__sum'] else 0 return f'{positive_movements_balance}' @admin.register(CoinWallet) class CoinWalletAdmin(admin.ModelAdmin): list_display = ('id', 'student', 'balance', 'total_coins', 'answer_coins', 'bonus_coins', ) search_fields = ('id', 'student') def get_queryset(self, request): queryset = super(CoinWalletAdmin, self).get_queryset(request) queryset = queryset.annotate(_total_coins=ExpressionWrapper(F('balance'), output_field=DecimalField())).order_by('_total_coins') return queryset def total_coins(self, obj): return obj._total_coins total_coins.admin_order_field = '_total_coins' I tried this, but, instead of balance, i want to add sortable for total_coins.

Request.urlopen does not work after moving the server to the cloud. use docker-compose django, nginx
Yesterday, I moved to the cloud while running the server locally. Based on ubuntu 20, the server is operated using docker, django, nginx, mariadb, certbot in docker-compose. is configured and operational. It has opened both 80:port and 443post to the cloud, and outbound is allowed in the cloud itself. In docker-compose, if you receive a request from 80 or 433 from nginx.conf to upstream django_nginx server container name: 8000 after mapping from docker-compose to 80 or 433 for the application --bind 0.0.0.0:8000 Jango. Proxy_pass http://django_nginx; is passing. The problem is that when an external api is called from a running django inside the docker container (e.g. request.urlopen(url) header included or not included), there is no response. So I gave the option request.url, timeout=3 and checked, and the https request causes We failed to reach a server /Reason: _ssl.c: 980: The handshake operation timed out http request causes We failed to reach a server /Reason: timed out. I used to run a server locally as a virtual machine, but it was a logic that was going on without a problem before, so I'm very embarrassed because it didn't work after the cloud transfer. I'm inquiring because I haven't made any progress … -
Stripe Subscription Update with Django and React
I have developed backend implementation for Stripe API calls to handle the following requests : urlpatterns = [ path('subscription', SubscriptionCreate.as_view(), name="create_subscription"), path('add_payment_method', PaymentIntentCreate.as_view(), name="add_payment_method"), path('delete_payment_method', PaymentIntentDelete.as_view(), name="add_payment_method"), path('customer', CustomerView.as_view(), name="customerview"), path('webhook', stripe_webhook, name="stripe_webhook") ] Here below are my models in Django backend to handle information regarding products and the customer : class Product(models.Model): class Plan(models.IntegerChoices): FREE = 0, _('Free') BASIC = 1, _('Basic') PREMIUM = 2, _('Premium') ENTENPRISE = 3, _('Enterprise') plan = models.PositiveSmallIntegerField(choices=Plan.choices, null=False, blank=False, default=Plan.FREE) stripe_plan_id = models.CharField(max_length=40) class Customer(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) stripe_customer_id = models.CharField(max_length=40, default="") product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True) stripe_subscription_id = models.CharField(max_length=40, default="") clientsecret = models.CharField(max_length=80, default="") active = models.BooleanField(default=True) Also I have a post_save function that is triggered by "User Creation in Django" which also creates a Stripe Customer associated with each user and a subscription with a FREE plan that does not require payment / card information : post_save.connect(post_save_customer_create, sender=settings.AUTH_USER_MODEL) stripe_subscription = stripe.Subscription.create( customer=customer.stripe_customer_id, items=[{"price": customer.product.stripe_plan_id},], payment_behavior='default_incomplete', payment_settings={'save_default_payment_method': 'on_subscription'}, expand=['latest_invoice.payment_intent'], ) However, when the user wants to upgrade their subscription from Free to Paid models (Basic, Premium, Enterprise) then payment method / card information is required.

How to generate Django / Python Test for view with LoginRequiredMixin and UserPassesTestMixin
I am trying for some time to test a view of mine that I have protected from access via LoginRequiredMixin and UserPassesTestMixin. Unfortunately I do not manage to write the appropriate test. here is the view. The special thing is, that the user must not only be logged in, but he must also belong to the group "Administrator" or "Supervisor". With this combination I have not yet managed to write a test. Please who can help me. Here is my View: class FeatureListView(LoginRequiredMixin, UserPassesTestMixin, ListView): model = FeatureFilm template_name = "project/feature-list.html" def test_func(self): if self.request.user.groups.filter(name="Administrator").exists(): return True elif self.request.user.groups.filter(name="Supervisor").exists(): return True elif self.request.user.groups.filter(name="Operator").exists(): return True else: return False def handle_no_permission(self): return redirect("access-denied") and here is a snippet of the url.py: urlpatterns = [ path("feature/list/", FeatureListView.as_view(), name="feature-list"), path( "feature/<int:pk>/date", FeatureDetailViewDate.as_view(), name="feature-detail-date", ), how would you test this FeatureListView and the template belongs to thank you very much! -
Django: How does one mock a method called in an api test?
I keep hitting a method scan_file() that should be mocked. It happens while calling self.client.post() in a django api test. The app setup is below, I've tried mocked the imported scan_file patch("myapp.views.scan_file") as well as the source location patch("myapp.utils.scan_file") neither work. # myapp.views.py from myapp.utils import scan_file class MyViewset(): def scan(): scan_file() # <- this should be mocked but its entering the code #myapp.utils.py def scan_file() -> bool: boolean_result = call_api() return boolean_result #test_api.py class MyAppTest(): def test_scan_endpoint(self): patcher = patch("myapp.views.scan_file") MockedScan = patcher.start() MockedScan.return_value = True # This post hits the scan_file code during the api # call but it should be mocked. resp = self.client.post( SCAN_ENDPOINT, data={ "file" :self.text_file, "field1" : "Progress" } ) I've also tried the following syntax for mocking, and tried including it in the test setup() as well: self.patcher = patch("myapp.views.scan_file") self.MockedScan = self.patcher.start() self.MockedScan.return_value = True -
How are Django's form assets (Media class) served?
The "Form Assets" page of Django says Django allows you to associate different files – like stylesheets and scripts – with the forms and widgets that require those assets. For example, if you want to use a calendar to render DateFields, you can define a custom Calendar widget. This widget can then be associated with the CSS and JavaScript that is required to render the calendar. When the Calendar widget is used on a form, Django is able to identify the CSS and JavaScript files that are required, and provide the list of file names in a form suitable for inclusion on your web page. Okay, but what component of Django takes those form assets and actually puts them in the page? I ask because I'm trying to use django-autocomplete-light (DAL) with django-bootstrap5 on a multi-select form with a many-to-many field. I've done all the installing, put the widget on my form field: class SomeForm(forms.ModelForm): class Meta: model = Something fields = ['things'] widgets = { 'things': autocomplete.ModelSelect2Multiple( url='myapp:things-autocomplete') } I can see the HTML for the form widget includes autocomplete-light stuff to multi-select "things" with "things" autocomplete: ... <select name="things" class="form-select" required id="id_things" data-autocomplete-light-language="en" data-autocomplete-light-url="/thing-autocomplete/" data-autocomplete-light-function="select2" multiple> </select> ... … -
Will I be able to use a wordpress site domain as a django website on a VPS?
I deleted all the files and folders associated with the Wordpress site I intend to write from scratch using standard HTML, JavaScript, CSS and with Django framework. My question is if I can use this domain with this newly created site in a VPS. At first I had erased the files and folders and recreated it with the Django app right onto the Wordpress structure, and that does not seem to be working. I am most likely doing something wrong anyways, but I am after the right way of accomplishing this. -
Django cannot migrate on Galera but MariaDB standalone works

I want to make a checkbox type filter on the items of an e-commerce

Django: Pass non-editable data from the client to the server
I am building a media tracker for TV shows and movies. When the user makes a query on the front-end, on the server I make a request with an API in which I get TV shows/movies with id, title, image link, media type, seasons, etc. After that, I display the result of the query on the front-end with the name and image: Then the user can select one of the results and get a simple form: The thing is that after submitting the form, I want to save the score and progress with the id, media type and other parameters that aren't shown on the front-end but are related to the media submitted. At the moment I am using to pass the values to the server: <input type="hidden" name="id" value="{{media.response.id}}"> The problem with this is that the user could change the id value with the developer tool (inspector), which would cause problems. I don't really know how to validate the form as the id could be any number. Is there a better and still simple approach? Thanks in advance -
Django_filter: filtering using current value of another field
So I was tasked with creating a events page where my company can post upcoming events and visitors can filter based on location, title or event type based on other 'is_virtual' which can be in person, virtual or hybrid. Now they want to 'ignore' the location filter if the event is virtual or hybrid but to keep it if the event is in person. I've been having issues accessing the value of the is_virtual field of the current object to create the conditional filtering based on it's value. here's the filter code: import django_filters from django import forms from .models import EventsPage class EventsFilter(django_filters.FilterSet): event_type = django_filters.ChoiceFilter( choices=EventsPage.event_choices, empty_label='Event Type', widget=forms.Select(attrs={'class': 'custom-select mb-2'}) ) location = django_filters.ChoiceFilter( choices=EventsPage.location_choices, empty_label='All Locations', widget=forms.Select(attrs={'class': 'custom-select mb-2'}) ) title = django_filters.CharFilter( lookup_expr='icontains', widget=forms.TextInput( attrs={'class': 'form-control', 'placeholder': 'Search Events'}) ) class Meta: model = EventsPage fields = ['event_type', 'location', 'title'] any ideas helps! thanks in advance. tried using the method keyword argument built in django_filter library and the values passed to the helper method only show the value of the current field but I can't see the current value of the is_virtual field. here's what I tried to do: location = django_filters.ChoiceFilter( method='location_filtering', choices=EventsPage.location_choices, empty_label='All … -
Django show exception in webpage instead of on console
I am launching a Django API from the console via the following command line: python3.10 manage.py runserver 0.0.0.0:8080 However, sometimes, when there is an error on one of the pages, like for instance if I import a python package that was not installed via pip, the webserver does not get launched, I get a python exception on the console, but no webserver is launched (the network port is not even listening). Is there a way to still have the webserver running and showing any exceptions or errors that might arise ? This API is for learning purposes, the students should only be able to deploy their code by doing a git push and the new code is deployed. But in case of an error that is not shown in the webpages they would not know what went wrong, they do not have access to the server to see the console. Thank you for your help. -
