django-ckeditor modal form does not change data on POST
I have a django project using django-ckeditor. I use HTMX to create a bootstrap modal to show my edit form. It renders correctly (I did add the ckeditor.js files at the end of the body in base.html). If I call my form by going to localhost/1/update, change the RTF value, and click save, it works fine. But rendering it in the modal form and clicking save, the form.has_changed() returns false. If I edit another field and it saves, the value of RTF does NOT change. It seems like the POST does not include the changed value for the CKEditor field. I've tried to reduce the code below to make it as short as possible. My model: class MyModel(models.Model): name = models.CharField(max_length=50) description = models.CharField(max_length=150) comment = RichTextField(blank=True, null=True) def __str__(self): return f'{self.name} - {self.description}' My form: class MyForm(forms.ModelForm): class Meta: model = MyModel fields = ( 'name', 'description', 'comment', ) My View def update_data(request, pk): model = MyModel.objects.get(id=pk) form = MyForm(request.POST or None, instance=model) if request.method == "POST": if form.is_valid(): print(form.has_changed()) form.save() return redirect("detail-form", pk=model.id) My HTML#1 - I click on the update button to open the modal {% extends "layouts/base.html" %} {% load static %} {% block content %} … -
Customizing model primary keys
I have model Mail which saves a mail object. Mail model also has a OneToMany relationship field, that is related to User(User can have many mails, but a mail can have only one owner(User object)). I need to implement its own primary keys reference system for each Mail object, because each mail is supposed to be related to an only one user to display urls the right way. For example if User-1 sends his first two mails in the whole app, they are saved with 1 and 2 id in the database, that's default django primary keys saving system. Then if User-2 sends his first mail, this mail is supposed to be saved with id 1, because it's first User-2 mail, but it's gonna be saved with id 3, because by default primary key reference system, the ids 1 and 2 are already taken. And this is the problem, because the url of first mail for User-2 will be displayed as /sent-mail/3, when it must be /sent-mail/1 So how to customize Mail model and implement it's own primary key references for each user. Here is the model: class Mail(models.Model): url_id = None title = models.CharField(max_length=64) body = models.CharField(max_length=1000) unvisited = … -

Django and Javascript How to Upload Multiple Images with Progress Bar
Good day, I am trying to upload multiple images in django with a progress bar. Currently, I have a working solution for only one image but now I want to add more fields and I need to show progress bar for all the images I am uploading. Below is my working code and the commented out code in the forms.py are the new fields I want to add. models.py class ProductImage(models.Model): product = models.OneToOneField(Product, on_delete=models.CASCADE, null=True, blank=True) main_image = models.ImageField(max_length=255, upload_to=get_product_image_additional_filepath, null=True, blank=True) img_one = models.ImageField(max_length=255, upload_to=get_product_image_additional_filepath, null=True, blank=True) img_two = models.ImageField(max_length=255, upload_to=get_product_image_additional_filepath, null=True, blank=True) img_three = models.ImageField(max_length=255, upload_to=get_product_image_additional_filepath, null=True, blank=True) img_four = models.ImageField(max_length=255, upload_to=get_product_image_additional_filepath, null=True, blank=True) img_five = models.ImageField(max_length=255, upload_to=get_product_image_additional_filepath, null=True, blank=True) forms.py class StoreDashboardProductUpdateForm(forms.ModelForm): class Meta: model = ProductImage fields = [ "main_image", # "img_one", # "img_two", # "img_three", # "img_four", # "img_five" ] views.py def store_dashboard_product_update_view(request, slug, product_slug, pk): product = get_object_or_404(Product, pk=pk) form = StoreDashboardProductUpdateForm(request.POST or None, request.FILES or None) if request.is_ajax(): if form.is_valid(): form.instance.product = product form.save() return JsonResponse({'message': 'hell yeah'}) context = { 'form': form, "object": product } return render(request, 'store/dashboard/product_update.html', context) {% extends 'store/dashboard/base/products-second.html' %} {% load crispy_forms_tags %} {% load widget_tweaks %} {% block content %} <style> .not-visible { display: none; } … -
Django. How to make ModelChoiceField work with SingleObjectMixin, FormView, and inlineformset_factory?
So, I have been trying to make it function as planned, but there might be a tweak away from my knowledge. The objective is to show only related options in a form with a choice field. Model CONTRATO register all contracts Model FATURA register all invoices and it has a ForeignKey with CONTRATO in a relation one-to-many (so one contract has many invoices) Model LANCAMENTO register records from contracts that will be later assigned to an invoice in FATURA. So LANCAMETNO has a ForeingKey with CONTRATO in a relation on-to-many (so one contract has many recors in LANCAMENTO). And LANCAMENTO also has a ForeignKey with FATURA, that is null by default, so later it will be assigned a FATURA to that record in LANCAEMTNO. The goal is to have this logic in a form. So when user goes to LANCAMETNO to assign a FATURA, it can choose only FATURA with the same contract_id as LANCAMETNO. I got here resarching a lot, but this is as far I can go. I'm stuck. Here's the code, in case someone could point me in the right direction. Here is my code for Models: from django.db import models from django.urls import reverse, reverse_lazy # … -

How to setup Vue.js SPA when starting it in HTML
I have a django application where I have an area that is made in Vue.js. I would like to know if it is possible to set parameters at the time of initialization of the Vue.js app in HTML. For example a token where the VueApp can use to authenticate and fetch some apis in django. Today it is being done like this: <body> <noscript> <strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong> </noscript> <div id="app"></div> <!-- built files will be auto injected --> <script> window.config = {{vue_config | safe}}; </script> <script type="text/javascript" src="{% static 'js/app.js' %}"></script> </body> And inside the VueApp I get the configs from window.config Is there a better way to do this? -
Is there a way in Django to order a model using a "custom filter logic"?
I'm currently having a problem in a personal project which involves ordering by 2 custom fields (limit_date and priority). Let's suppose a model like: PRIORITY_CHOICES = [ ("red", "Red"), ("yellow", "Yellow"), ("green", "Green") ] class Todo(models.Model): limit_date = models.DateField() priority = models.CharField(choices=PRIORITY_CHOICES, max_length=15, blank=False, null=True) Let's suppose i want to order them following the following logic: if <current_todo>.priority == 'red': priority_scale = 3 elif <current_todo>.priority == 'yellow': priority_scale = 2 else: priority_scale = 1 priority_scale_with_date = <current_todo>.limit_date - datetime.today() * (<current_todo>.priority_scale) I know i can do some things with "conditional expressions" to get priorities as values, like: Todo.objects.annotate( priority_scale=Case( When(priority='red', then=Value(3)), When(priority='yellow', then=Value(2)), When(priority='green', then=Value(1)), default=Value(0), output_field=models.IntegerField())).order_by('-priority_scale', 'limit_date') But i don't know how can i put them all "together". Let's suppose a object with priority 'red' (value 3), with two days left to be done and another one with priority 'green' (value 1) with one day to be done. Their priorities will be something like: first_obj = 1 * 3 = 3 (days untill limit_date and 'priority_scale') second_obj = 2 * 1 = 2 (days untill limit_date and 'priority_scale') What i want, is to order them with a "junction" of 'priority_scale' and 'limit_date'. I am very confused here and sorry … -

Loading Screen for a Form
I am trying to make a loading screen when submitting a form. When I submit a form the page starts to load until the backend responds by downloading an excel file.

Why does SSE work locally, but not when hosted on IIS?
I'm using Django eventstream for SSE and Channels (I'm not able to use Memurai or Redis). When I run the local server, everything works great. The user can submit a file, that information is ran against the external 3rd party API it calls, and real time information is displayed back to the browser from the /events/ URL API. When configuring through IIS, everything works great EXCEPT the /events/ URL is unreachable (404), so the SSE connection doesn't get initiated which halts everything in it's tracks and I'm looking at a blank template that should be getting populated in real time. WebApp is hosted for local network only.

How can I break up a Django request into multiple requests?
I wanna do the following inside a Django REST ModelViewSet: receive data from an HTTP POST request break the data into several pieces pass the pieces to different ViewSets that should handle authentication, etc. based on the original request Background is the following: I have a working REST implementation with normal ModelViewSets for all endpoints and now I'm implementing a syncing protocol for a Progressive Web App that should work completely offline. The idea is that the normal ViewSets keep working and I implement the custom logic only once in the ViewSets. But I want to be able to collect request data offline and send all at once (also to guarantee order). Then the "sync" endpoint breaks the data apart and passes it to the respective views. I'm only missing a copy of the request object with adjusted data... What I tried to far: deepcopy of the request object does not work I have a hard time figuring out how to construct a request from scratch that mimics the original -

Django and Python logging what is the full dictionary for the formatter?
Apologies if the title is vague. Feel free to edit to include the correct terminology. In settings.py, I have the LOGGING dictionary with this formatter: 'formatters': { 'standard': { 'format': '{asctime} {message}', 'style' : '{', } I understand that asctime is the time that the log message was generated, and message is the message itself. But I don't know what other options are available. Is the message itself a Python dictionary, and the curly-braced items are keys in the dict? How can I view all keys in that dictionary? I assume {severity} is in there somewhere. What else can I enter? Also, what are the various options under 'style'? -
