My problem with getting the current month as default in django

Django, The static files (CSS, fonts) uploaded to the media folder from external sources cannot be used from the media folder
I have an index.html file and a verdana.ttf font file uploaded within a zip file. I use this font embedded in index.html as they are in the same folder. I provide a relative path like this: @font-face { font-family: Verdana_Bold; src: url(verdana.ttf); } If I provide a font file from a remote server as the src, it works. However, it cannot access a locally available file (in the media folder). I've tried some possibilities like: /media/verdana.ttf /code/media/verdana.ttf (my root directory structure due to Docker usage) But it always gives the error: 'The joined path (/media/verdana.ttf) is located outside of the base path component (/usr/local/lib/python3.8/site-packages/django/contrib/admin/static).' I want to dynamically provide HTML template files, including font and CSS static files from an external source and use them. My goal is to generate PDFs from HTML templates. I've created a service for users to create their own templates. Maybe moving the file to the static folder after uploading and running the 'python manage.py collectstatic' command might work. I haven't tried that yet, but I would prefer not to use this solution -

django-tables2: sorting does not function on a table of related data
I have two classes: Project which has a many-to-one relationship with Client. I would like my detailed template of Client to display a list of projects. The code below successfully gets the required Projects, and stores them in context, which is then passed to the template renderer which renders them successfully. So far, so good. But the rendered table will not "sort" the data successfully. I can click on the headers, which will add ?sort=name to the request, but nothing happens. Is this the correct approach for what I am intending, and if so, what step am I missing to get the full functionality? models.py class Client(models.Model): name = models.CharField("Name", max_length=300, unique=True) class Project(models.Model): client = models.ForeignKey("Client", on_delete=models.RESTRICT) name = models.CharField("Name", max_length=300, unique=True) tables.py import django_tables2 as tables from .models import * class ProjectTable(tables.Table): class Meta: model = Project template_name = "django_tables2/bootstrap.html" fields = ("name", ) views.py class ClientDetailView(DetailView): model = Client def get_context_data(self, **kwargs): # Get related Projects and put then in 'table' table = ProjectTable(self.object.project_set.all()) # Add 'table' to 'context' context = super(ClientDetailView, self).get_context_data(**kwargs) context['table'] = table return context html {% load render_table from django_tables2 %} {% render_table table %} -

Django logging output that doesn't seem to be part of root
I'm trying to understand Django's logging output so I've separated out all the core django loggers (django, django.request, django.db.backend, core, django.template) and set their levels to WARNING and gave it it's own formatter to make it more easily distinguishable from the rest. I've also overridden the root logger, set it to debug and made a similar easy to notice formatter for it. So now I get stuff like this: 127.0.0.1:99999 - - [08/Nov/2023:00:50:06] "GET /static/frontend/main.js" 304 - ROOT CRAP ! >>>>>>> [2023-11-07 16:50:10] - daphne.http_protocol - HTTP response complete for ['127.0.0.1', 99999] 127.0.0.1:99999 - - [08/Nov/2023:00:50:10] "GET /api/auth/user" 200 606 ROOT CRAP ! >>>>>>> [2023-11-07 16:50:12] - daphne.http_protocol - HTTP 200 response started for ['127.0.0.1', 99999] ROOT CRAP ! >>>>>>> [2023-11-07 16:50:12] - daphne.http_protocol - HTTP close for ['127.0.0.1', 99999] ROOT CRAP ! >>>>>>> [2023-11-07 16:50:12] - daphne.http_protocol - HTTP response complete for ['127.0.0.1', 99999] 127.0.0.1:99999 - - [08/Nov/2023:00:50:12] "POST /sg/query/user_tasks" 200 6001 But I still don't know where those REST logs are originating from (ie the ones that don't say ROOT CRAP!).

failed to authenticate multiple user in django
I have multiple user models in my Django app, one for OLAROOM and the other one for REALTOR. As you can see, everything is working successfully, but when I try to authenticate them and redirect them based on their role, it does not work. The authentication is working fine, but instead of redirecting the Olaroom user to the Rooms page, it is redirecting me to the Realtor_Dashboard, and the user role isn't a Realtor. Using the form below, the user is created based on what is defined in the save function. However, when I try to authenticate them and redirect the user to the page based on their role, it doesn't work, and I'm using the same method, something like this: user.Role.REALTOR and user.Role.OLAROOM. How can I solve this problem please? def login(request): if request.method == 'POST': form = AuthenticationForm(data=request.POST) if form.is_valid(): username = request.POST.get('username') password = request.POST.get('password') user = authenticate(username=username, password=password) if user is not None: if user.Role.REALTOR: auth_login(request, user) return redirect('Realtor_Dashboard') elif user.Role.OLAROOM: auth_login(request, user) return redirect('Rooms') else: messages.error(request, 'Invalid Creadentials') else: form = AuthenticationForm() return render(request, 'Login/login.html', {'form':form}) User Models class User(AbstractUser): class Role(models.TextChoices): ADMIN = "ADMIN", 'Admin' REALTOR = "REALTOR", 'Realtor' OLAROOM = "OLAROOM", 'Olaroom' base_role … -

UseEffect in React Components in Django App

In the first step it is working: the react components are beeing rendered and everything looks fine. The problem: I have a component let's say a table, where lets say Artikel/ price data are rendered. Now due to another non-React functionality new data are uploaded from the users desktop. Of course the table should be re-rendered. But how can this be managed? I tried to solve it with useEffect and a global variable. Apart from the fact that this seems to be a anti-pattern it simply doesn't work. So the question is, how can I solve this problem? I don't have an idea. I tried any kind of research and manipulation around the usage of global variables within this context. Unfortunately without any result. -
DJango captcha Error messages getting duplicated
my captcha error messages get duplicated my template error display code: {% if form.non_field_errors %} {% for error in form.non_field_errors %} <h3 style = "color:red;text-align:center">{{ error }}</h3> {% endfor %} {% elif messages %} {% for message in messages %} <h3 class = "{% if message.tags == 'success' %} message-green {% elif message.tags == 'error' %} message-red {% endif %}" style = "text-align:center">{{message}}</h3> {% endfor %} {% endif %} and my views: def Insertvalue(request): if request.method == "POST": form = EmpInsertForm(request.POST) if form.is_valid(): form.URL = request.POST.get('URL') form.email = request.POST.get('email') form.save() messages.success(request,'Info saved. Be on the lookout for a confirmation e-mail') else: messages.error(request,'Captcha not cleared. Please try again.') return render(request,'Index.html',{"form":form}) else: form = EmpInsertForm() return render(request,'Index.html',{"form":form}) the messages.error is the one that gets duplicated. to reproduce it, I first have to get the non field error which is bascally a unique_together error, and then get the captcha error and it will be printed as many times as I got the non field error + 1. Is there any way to delete all messages in the messages array if non field error is raised? Thank you in advanced.
