Django 3 rendering markdown break on newline
I have literally tried all the current markdown rendering libraries for Django (also not so current) Django Markdownify, Django Markdown 2 and Markdown Deux) and all have the same problem as described in this old question: How do I make django's markdown filter transform a carriage return to <br />? basically carriage returns is disregarded on rending. If I do {post.body|markdown|linebreaksbr}} it always results in 2 <p><p>1 line</p><br><br><p>1 line</p><br><br><p>2lines </p><br><br><p>2 lines </p><br><br><p> so my options are either none or 2 BR. I am confident that there is an easy solution for this. I can't believe that none of the Django libraries provides this minimal functionaly. -

How can I run a Django 3 project with a MySQL server set on a NAS (Synology DS120J) using phpMyAdmin and MariaDB 10?
I appreciate the fact that the topic is quite specific, but I have been struggling to find documentation on such setup. I am working on a Django 3 project using Python 3.9, instead of SQLite3, the application would be using a MySQL server hosted on a Synology DS120J NAS, this is done via phpMyAdmin and MariaDB 10. Basically, my objective is to run the Django 3 application from my PC (Windows 10), and the MySQL server from the NAS. Both are sharing the same local network. Is anyone using a similar setup? If so could you please provide with some guidance? At the moment here is the DATABASES section of the settings.py file from the application: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'gaia', 'USER': 'root', 'PASSWORD': [phpMyAdmin password], 'HOST': '127.0.0.1', 'PORT': '[port number of the MariaDB 10 server on phpMyAdmin]' } } I launch the application using the following command: python manage.py runserver 192.168.0.2:[port number of the NAS]. When doing so, I get the following error message: django.db.utils.OperationalError: (2002, "Can't connect to MySQL server on '127.0.0.1' (10061)"). I have searched for this error message but didn’t get anything very helpful as I wasn’t sure whether any of the … -

Pylint-django raising error about Django not being configured when that's not the case (VSCode)
Pylint-django worked just fine up to version 2.3.x but since 2.4.0 it reports an error on every python-django file: Django was not configured. For more information runpylint --load-plugins=pylint_django --help-msg=django-not-configuredpylint(django-not-configured) This happens on VSCode and I believe I have it correctly configured: { "python.linting.pylintArgs": [ "--load-plugins", "pylint_django", "--load-plugins", "pylint_django.checkers.migrations", "--disable=C0114, C0115, W0222", "--disable=imported-auth-user", "--disable=invalid-name", "--disable=line-too-long" ] } This worked perfectly fine, as I said, up to v.2.3. I raised an issue on their repository but regrettably it was dismissed with little to no visible effort to address it. For the time being I'm staying with v.2.3.0, which lints with no issues with the above configuration, but would like to know if this is a bug or otherwise. Did any get into this issue or is it there anything else I'm missing? -
Prepend Serialized object with name
I have the following setup for my ListSerializer, which is called with a URL looking like "api/tax/2021-03-30": models.py class CityTax(models.Model): class Meta: verbose_name = "City Tax" verbose_name_plural = "City Taxes" season = models.ForeignKey(Season, on_delete=models.CASCADE, null=True) hotel = models.ForeignKey(Hotels, on_delete=models.CASCADE) EUR = models.DecimalField(max_digits=5, decimal_places=2) USD = models.DecimalField(max_digits=5, decimal_places=2) serializers.py class TaxSerializer(serializers.ModelSerializer): hotel = serializers.CharField(source="hotel.abbrev") season = serializers.CharField(source="season.title") class Meta: model = CityTax exclude = ['id'] api_views.py class TaxList(ListAPIView): serializer_class = TaxSerializer def get_queryset(self): """ Get city tax for appropriate season according to date of arrival """ url_date = date.fromisoformat(self.kwargs['start_date']) seasons = Season.objects.all() selected_season = Season.objects.get(start_date__lte=url_date, end_date__gt=url_date) return CityTax.objects.filter(season__title=selected_season) which returns a response that looks as follows: [ { "hotel": "DDC", "season": "A20", "EUR": "1.00", "USD": "1.19" }, { "hotel": "DSF", "season": "A20", "EUR": "1.13", "USD": "1.34" }, ] How can I prepend the result to look like this: [ "DDC" { "hotel": "DDC", "season": "A20", "EUR": "1.00", "USD": "1.19" }, "DSF" { "hotel": "DSF", "season": "A20", "EUR": "1.13", "USD": "1.34" }, ] I've been trying to figure out how to make this happen, but I feel like I'm looking in the wrong places (nesting serializers?)

Use Vue components in application at runtime
I am developing a small application using Vue which will have list of downloadable components available to the user. Downloadable components will be hosted somewhere on the webserver(compiled version of SFC's) seperately. List of components can be increased or decreased based on users permissions. This application will be shared with the user to download the components of their choice and add them to the list. Problem is am not getting any examples in the internet where compiled components are used inside compiled Vue apps at runtime. All the available examples need compiled components to be registered or to be imported in the applications in order to use it. The only way right now is to chuck the idea of using ES6 or (.vue) Single file Components luxury and use ES5 version which i don't want to. Can anyone help me out? Backend used is Django -
Django: How to realize App structure for specific program (picture)
I'm new to Python/Django and I would like to rewrite an old program as a web application The picture is a screenshot of the program. As you can see there are multiple tabs on the left and two on the top (marked red) so the programm ist kind of nested(?). All of the Tabs work together to calculate the end result. Im kind of overwhelmed so my first question is how to structure the Programm in Django using apps. Is each Tab one app and I link them all together? Also is there a template for tab-style menue? Thank you very much, hope ich can get it realized :D Programm_Image -
Design pattern of coupling/decoupling two apps in Django
I have two apps: app1 and app2. =>app1 has model A gets data with timestamps. =>app2 has model B with some computations that have to be made on the data that model A gets Usecase:. Every time we create model B, it has to check if we have enough data in model A => do an update. This same update is triggered every time we add data to model A. => My design is: since updates are having a place in model B then I import my model A in it and check if I have enough data while creating model B. on the other way around, if I add data to model A I prefer not importing model B in model A to avoid app circular dependencies and coupling. So my idea here is to send a signal from model A to model B and proceeds to the update, is it the best way to do it or you would think of some different design patterns? => I also read on some blogs that using signals is not always suggested, what's your take on this? -

Django unit test remove Files created inside the tests
I'm using DRF view tests. Inside my tests I create files which I want to remove after the tests were running. I'm using addCleanup inside my setUp method to remove the directories. It basically works, but when I run my complete set of unit tests one dir won't be deleted (I think it's the first one created). Here is the relevant code: class BaseViewTest(APITestCase): client = APIClient() base_media_root = settings.MEDIA_ROOT def setUp(self): settings.MEDIA_ROOT = tempfile.mkdtemp(dir=self.base_media_root) # add test data self.addCleanup(shutil.rmtree, settings.MEDIA_ROOT) -
Django {% if object.foreignkey %} returns the opposite of the value
So I have two models. First one is Collection Title and second one is Title Status. In Title Status I have a foreignkey named collection_title_status that points to CollectionTitle. I have rendered the form TitleStatusForm inside my collection_title_detail.html with a DetailView and a FormMixin. The form is in a modal. Globally, this part works, meaning that I can fill the form, and it saves the data and creates a link between the Collection Title and the Foreign Key of Title Status (for example, if CollectionTitle id is 61, my collection_title_status value will be 61 as well). What I want to do : If Collection Title is not linked to a Title Status (meaning the user as not initiate the Status monitoring yet), then I want to display the button called 'Initiate' that opens the modal containing TitleStatusForm to initiate the Title Status model If Collection Title is already linked to a Title Status (which should be done after fulfilling the first step above), then I don't want to display the above mentionned button and modal. Instead, I want to display the values previously entered by the user for each field. So here is how I tried to do it : … -
