Should I render dynamic charts in Django or serve them from another webapp?
Here is this Django webapp hosted in a Apache2 server with mod_wsgi My question is: How do I add dynamic graphs to my webapp? In producion, in order to serve files, Nginx reverse proxy server catches the urls with the /static/ subdomain and serves the content (otherwise the request is redirected to apache) Google returns planty of ways to address the matter. Do you have any recomandation or relatable experience that I should know before choosing any? My concerns are: How clients update graph data without refreshing the whole page ? (I currentlly use htmx for rendering html) Should I use a second webapp to serve the content to nginx redirect? Is django-plotly-dash the most straight way? Will it work with htmx or else? I tried to periodically render an html with a plotly graph using htmx; resulted awful -

Django: prevent Form to crash when akward date format is used
I have a form: class EditProfileForm(forms.ModelForm): template_name = 'users/edit_profile.html' def __init__(self, *args, **kwargs): super(EditProfileForm, self).__init__(*args, **kwargs) self.fields['email'].help_text = _( 'Providing your email would enable you to recover your lost password') class Meta: model = get_user_model() fields = ( 'first_name', 'last_name', 'email', 'birthday', 'language', 'headshot', ) with user model: class CustomUser(AbstractUser): birth_year = models.PositiveIntegerField( verbose_name=_('Birth year'), default=0) birthday = models.DateField(verbose_name=_( "birthday"), null=True, blank=True) headshot = models.ImageField(verbose_name=_('Avatar'), null=True, blank=True, default='user_headshots/user.png', upload_to="user_headshots/") language = models.CharField(verbose_name=_('Language'), max_length=10, choices=settings.LANGUAGES, default=settings.LANGUAGE_CODE) I had a user use a strange format for birthday "25,2,96", which led the django application to crash: The view users.views.edit_user_profile didn't return an HttpResponse object. It returned None instead. not much more information in the Traceback !?! Looking into the django code and internet, I was amazed that the DateField formfields did not come with embedded validators There are plenty of information on internet about setting specific dateformats for a specific DateField, but I wasn't able to find one kind of best practice that would work with all sort of localized date formats. Everything I found is very complicated for such a trivial issue, and I'm pretty sure there is a neat and easy to implement solution. Any suggestion? -

Best Explanation on the implementation of Dependency Injection in Python.?
I am a Software Engineer with significant amount of years of experience. I always desire using core development principles in my projects and these include using DI. which I have used alot in .NET projects and in Nodejs Projects. however I can't wrap my head around how DI actully works in python projects especially using FLask or Django. The examples I have seen are not really conidered DI to me. Would appreciate a good explanation. Thanks. I simply want to apply DI in future Django and Flask Projects. -

How to dynamically add markers using Folium and JavaScript based on user input coordinates?

Access to contents of the selected object in a Django OneToOneField
I would like to retrieve specific field data from a selected object within a OneToOneField relation. I have three models: Model1 contains the 'malfunction_1' field, which I intend to copy into the 'malfunction_3' field within Model3. Model2 possesses the OneToOneField. When a Model2 object is created and an object is chosen within the OneToOneField, another Model3 object should be generated. The content from 'malfunction_1' (Model1) and 'dynamik_2' (Model2) should then be duplicated into 'malfunction_3' and 'dynamik_3' fields, respectively. class Model1(models.Model): malfunction_1 = models.CharField(max_length=255, null=True, default=None) class Model2(models.Model): given_malfunctions = models.OneToOneField(Model1, blank=True, on_delete=models.CASCADE, default=None) dynamik_2 = models.CharField(max_length=255, default=None, blank=True) class Model3(models.Model): connection_to_model2 = models.ForeignKey(Model2, on_delete=models.CASCADE, default=None) malfunction_3 = models.CharField(max_length=255, null=True, default=None, blank=True) dynamik_3 = models.CharField(max_length=255, default=None, blank=True) would you use a receiver method or define a normal function for this use case? -
How to make django not duplicate custom class logs
I wrote MyClass which i'm using inside of DRF ViewSet "create" method. In this class i declared new logger with _set_logger method. The problem is that django duplicates MyClass logs, which I don't want: MyClass _set_logger method: import logging class MyClass: def _set_logger(self) -> None: self.log = logging.getLogger('logger_name') sh = logging.StreamHandler() sh.setLevel(logging.ERROR) formatter = logging.Formatter( "%(name)s | %(levelname)s | %(funcName)s | %(message)s" ) sh.setFormatter(formatter) self.log.addHandler(sh) The way i'm using MyClass in ViewSet "create" method: class SomeViewSet(ModelViewSet): def create(self, request, *args, **kwargs): obj = MyClass() obj.do_something(request) return super().create(request, *args, **kwargs) Logs: # my logs logger_name | funcName | CRITICAL | error_msg # django logs CRITICAL 2023-08-17 00:10:44,138 module_name 11 140294782023360 error_msg I tried changing logger_name to __name__ , expecting django and MyClass to use the same logger, but that didn't happen. class MyClass: def _set_logger(self) -> None: self.log = logging.getLogger(__name__) -
How to initialize Django database without using existing migrations?
I have a Django project, which contains dozens of migrations, and I want to initialize it on a new database. How do I do this without running all the migrations, which can take a lot of time to run? In earlier versions of Django, it used to have a "syncdb" command that you could run to create all tables in a blank database, bypassing all migrations. Current Django's migrate command has a --run-syncdb option, but the docs say: Creates tables for apps without migrations. Since all my apps have migrations, I interpret this to mean it does nothing in my case. Does modern Django no longer have anyway to initialize a database without tediously running through every single migration? Note, I'm not asking how to initialize a Django database. I'm asking how to do it more efficiently than by running migrations, which are designed to modify an existing database, not initialize one from scratch. -
Save generated image to model AND upload to S3?
I cannot find documentation on how to do what I need to do. My goal(s): User fills out a form with basic info Server-side a qr code is generated for that user. This qr code image needs to be uploaded to S3 to not bog down the server storage. This needs to be referenced in a model. WHY? This image will need to be displayed later in various front-end frameworks so at least the URL should be somewhere. It is stated lower but note: the s3 upload IS functional via form in admin.
