Add second non null condition to Django FilterSet
How do you add a non-null constraint to a second field on a drf_filters.FilterSet? In the case below, I would like to impose a second constraint that the model field called "obsolete" is not None. class MyFilterSet(drf_filters.FilterSet): uploaded = drf_filters.IsoDateTimeFilter( field_name='uploaded_at', lookup_expr='gt', required=True ) -
Django EmailMessage return error in django_rq task
I am trying to make a simple mail sending service with django. Without the use of the queue everything works fine, but as soon as I add the use of django_rq an error occurs at the time of executing msg.send() class SendEmailSerializer(serializers.Serializer): email_to = serializers.ListField(write_only=True) subject = serializers.CharField(write_only=True) template_name = serializers.CharField(write_only=True) template_data = serializers.DictField(write_only=True) def create(self, validated_data): send_email_wrapper( emails_to=validated_data.get("email_to"), subject=validated_data.get("subject"), template_name=validated_data.get("template_name"), template_data=validated_data.get("template_data") ) return {} import os, django_rq from sizze_email.settings import BASE_DIR from django.conf import settings from django.template.loader import render_to_string from django.core.mail import get_connection, EmailMessage FROM_EMAIL = getattr(settings, 'EMAIL_FROM') def find_template(template_name): for root, dirs, files in os.walk(os.path.join(BASE_DIR, "templates")): if template_name in files: result = os.path.join(root, template_name) return result def send_emails(emails_to, subject, template_name, template_data): template = find_template(template_name=template_name) message = render_to_string(template, template_data) connection = get_connection() step = 100 for index in range(0, len(emails_to), step): msg = EmailMessage( subject=subject, body=message, from_email=FROM_EMAIL, bcc=emails_to[index:index+step], connection=connection ) msg.content_subtype = "html" msg.send() def send_email_wrapper(emails_to, subject, template_name, template_data): django_rq.enqueue(func=send_emails, emails_to=emails_to, subject=subject, template_name=template_name, template_data=template_data) I use amazon ses to send mail, django-rq performs other tasks, and if I remove sending mail from the task, then everything will work fine.

Filter with just an input field for an id
Django 4.1 In my admin site I often use raw_id_fields. But in this case it is strange that filter uses just lists of instances. I would prefer to have a filter with an input field for an id as the number of objects being filtered is immense. Is it possible to have such a filter? Maybe there is a ready made third party application? -
How to change URL for all already uploaded files in filefield after changing upload_to
What happened I changed the server for my Django application .. and I have filefield that was uploaded already and the field was like below: image = models.FileField(upload_to="uploads", verbose_name=_( "Team Strips"), help_text=_("A Strip to be used later by users")) But I the new server am forced to use a different path so I had to change it to be like image = models.FileField(upload_to="ldawri_django/uploads/uploads", verbose_name=_( "Team Strips"), help_text=_("A Strip to be used later by users")) Settings.py MEDIA_ROOT = '/home/wateopjw/l-dawri.com/ldawri_django/uploads/' MEDIA_URL = "ldawri_django/uploads/" The Problem After changing the server and upload_to parameter all images are not showing now inside the Admin panel .. but it is shown when I click open image in new tab.

Django: Fix order issue with list of objects
I have a function that gets queryset results from the database and does some manipulations. When I get the results of that list, somehow the order is changed. And exactly this is the function that makes the order change: schedules = list(set(schedule_list) - set(excluded_schedules)) So I will explain exactly: I want to display the availability of a professional for booking an appointment. This professional has a list of available slots. When the visitor loads the professional profile page, Django makes a query to get all time slots of the professional, and then gets all the existing appointments, then proceeds to remove the booked schedules from the total schedules, to display the rest (the available schedules). So far so good? So, the code is the following (edited for sensitive information): def get_home_schedules(date, professional): day = get_day_by_date(date) try: schedules = Schedule.objects.filter(professional=professional, day=day, stype="Home").order_by('timefrom') excluded_schedules = [] schedule_list = [] for s in schedules: new_appointments = s.appointments.filter(schedule=s, date=date, status='New') confirmed_appointments = s.appointments.filter(schedule=s, date=date, status='Confirmed') appointments = chain(new_appointments,confirmed_appointments) schedule_list.append(s) if appointments: for a in appointments: excluded_schedules.append(a.schedule) schedules = list(set(schedule_list) - set(excluded_schedules)) return schedules except: return None The schedule model is: class Schedule(models.Model): professional = models.ForeignKey(d, on_delete=models.CASCADE) timefrom = models.CharField(max_length=5, choices=HOURTIME, default="00:00") timeto = models.CharField(max_length=5, … -
How to check which message in Django

How to insert multiple rows of data from dynamically generated rows into a database using Python Django
I have a Javascript function (addItem) that allows a user to add any number of dynamically generated rows of data and fill in the necessary fields required. See code below <div class="modal-body"> <table class="table order-list table-striped" id="myTable"> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody id="addItems"> </tbody> </table> <table> <tbody> <tr> <td colspan="5" style="text-align: left;"> <button onclick="addItem();" class="btn btn-sm btn-success" id="sspusd1" value="Add Row"><i class="fa fa-plus"></i>Add Row</button> </td> <td colspan="5" style="text-align: left;"> </td> </tr> </tbody> </table> </div> function addItem() { renumber++; var html = "<tr>"; html += "<td><select class='form-control'>{% for stock in stocks %}<option class='dropdown-item' value='{{stock.inventoryPart}}'>{{stock.inventoryPart}}</option>{% endfor %}</select></td>"; html += "<td><input type='number' class='form-control' onblur='lineTotal(this);' value='0' name='quantity[]'/></td>"; html += "<td><input type='text' class='form-control' onblur='lineTotal(this);' value='0' name='price[]'/></td>"; html += "<td><input type='text' id='lineTotal' class='form-control' value='0' disabled name='total[]' /></td>"; html += "</tr>"; document.getElementById("addItems").insertRow().innerHTML = html; }; However, One is able to insert any number of rows they want and insert the necessary data into the fields available. The problem is that I am unable to capture and store the dynamic information entered into these dynamic rows since Django is unaware of how many rows a user has created. The aim is to be able to store the data from the created dynamic rows inserted by … -
Django + React axios POST cant access Json properties
I created two abjects that need to be treated separated in the backend, and sent it to backend with: const order = { order_id: 1, customer: { name: "Jonas Illver" age: 18 } } const car = { model: 'XHL' brand: 'Toyota' } const postData = { order: order, car: car } const res = await axios.post("orders/shipping/create", JSON.stringify(postData)); console.log(res); And here I return the response: views.py @api_view(['POST']) @permission_classes([IsAuthenticated]) def shipping_create_order(request): if request.method == 'POST': return JsonResponse(request.POST) Here's what the console.log prints: res.data // {"order:"{"order_id": 1, "customer": {"name": "Jonas Illver", "age": 18}}, "car": **car object content**} The problem is that if I try to access those data in my django view, I always got a 500 error I tried accessing it via: order = request.POST['order'] # and also data = json.loads(request.POST) order = data['order'] # also order = request.POST.get('order') None os the above approaches worked, the only one that doesn't occurs an 500 error is the last one, using the POST.get, but as soon as I add the if not order: return HttpResponse("No order") line, it always return "No order" How can I access specific info from the request.POST? Am I doing something wrong with the axios request? -

How to append a list in a dict from a JSONFeild in django
I want to use get_or_create() to search for an object. If it doesn't exist, it gets created.

How do you drop a specific migration that has no use currently and cause some errors when running tests?
I have a custom migration that is used to create a model object in the DB as a follow-up change, It adds a new option to the DB that was added later after the initial options list was created. I did that for the sake of automation and to avoid adding it manually. Now, a problem arises when running tests, all migrations run and therefore the first migration that creates the updated options list is applied, then that later custom migration is being applied and tries to create and it causes errors. So, my question is how to drop that migration. it was used for production DB to keep up but now it has no use for freshly DBs and causes errors Thank you for your answers and help -

Highlight the selected part in the table of contents (htmx)
I use django-htmx to create the table of contents. It works fine, but I can't select the selected part of the table of contents. I understand that it can be done with a url, but I'm shown a different address where the htmx itself is located. And the request.htmx.current_url command outputs a link without the parts in the table of contents. For example, the article is located at example.com/post/harry_potter , if I click on a certain part of the table of contents, the address will already be example.com/post/harry_potter#II. The request.htmx.current_url command gives a link to example.com/post/harry_potter , so I can't check in any way. this is the latest attempt, but it doesn't work <div class="offcanvas-body"> <nav id="navbar-example3" class="h-100 flex-column align-items-stretch pe-4 border-end"> <nav class="nav nav-pills flex-column"> <ul class="list-unstyled fw-normal pb-2 small"> {% for new in table_content %} {% if request.htmx.current_url == new %} <li><a href="#{{new}}" class="bd-links-link d-inline-block rounded nav-link active">{{new}}</a></li> {% else %} <li><a href="#{{new}}" class="bd-links-link d-inline-block rounded nav-link">{{new}}</a></li> {% endif %} {% endfor %} </ul> </nav> </nav> </div> -

Django architecture for different clients/technologies using same models
My team and I are having a hard time defining the architecture for my backend environment using Django. To contextualize a little, we built an application similar to an App Store, for all our developments to be displayed, with the difference that it also launches the apps. To maintain all the information about this apps, we built this backend in Django that is basically a database accessed through an API from the App Store, and a Django Admin website to register the informations to be delivered in the API (the one Django automatically generates).
