Initial Dropdown Menu Table Population
I was wondering if someone could help me solve this problem I have. I created a form that populates a table based on the selected name in a dropdown menu, however, when I initially load the page, since it is a for-loop and no option has been selected yet, the for loop runs through all the datapoints, populating the table with all the data for each name, but works fine once an option is chosen. I was wondering if someone could explain how I can get the initial page load to either show nothing or the values of one option, not everything at once until an option is chosen. Thanks for the help. <form method="GET" action="."> <div id="option-wrap"> <select name="option-menu" id="option-menu"> <option value="" hidden disabled selected value id="option-filler">Choose a Name</option> {% for l in options %} <option value="{{loans.company_name}}">{{l.names}}</option> {% endfor %} </select> <button type="submit" class="btn-filter">Filter</button> </div> <div class="card-items"> <table class="main-items-table"> <tr> <td class="menu-box-tab-items-identifiers">Name:</td> {% for l in queryset %} <td class="menu-box-tab-items" href=""><span>{{l.name}}</span></td> {% endfor %} <td class="menu-box-tab-items-identifiers">Sector:</td> {% for l in queryset %} <td class="menu-box-tab-items" href="#6"><span>{{l.sector}}</span></td> {% endfor %} </tr> </tbody> </table> </div> </form> -

Elegant way to handle invalid pages in Django with a generic class-based view
I found a partial solution in Django: How to catch InvalidPage exception in class-based views?, but the URL in the address bar still shows the original page request. Django has Paginator.get_page(number), but there doesn't seem to be a way to use it to redirect inside of the view. I originally thought I might be able to do it in get_context_data, but I don't seem to be able to force a redirect as it will only allow a dict as a response. def get_context_data(self, **kwargs): paginator = self.get_paginator(self.queryset,self.paginate_by,self.paginate_orphans) try: context = super().get_context_data(**kwargs) except Http404 as err: self.kwargs['page'] = paginator.get_page(self.request.GET['page']).number return redirect('my_list_view', kwargs=self.kwargs) context['page_list'] = context['paginator'].get_elided_page_range(context['page_obj'].number,on_each_side=2,on_ends=1) return context That fails outright. The following works (per the linked answer above), but does so in a non-optimal way. def get_context_data(self, **kwargs): paginator = self.get_paginator(self.queryset,self.paginate_by,self.paginate_orphans) try: context = super().get_context_data(**kwargs) except Http404 as err: self.kwargs['page'] = paginator.get_page(self.request.GET['page']).number context = super().get_context_data(**kwargs) context['page_list'] = context['paginator'].get_elided_page_range(context['page_obj'].number,on_each_side=2,on_ends=1) return context I feel like there should be a simple/elegant way to do this, but I just haven't found one. I could of course go for a function-based view, but I can't shake the feeling that there's got to be a way to do it this way. -
Django - how to make frontend-customizable sets / groups in models?
I am trying to create an app, that handles laboratory analyses - something like similar Laboraotory Information System (LIS) The issue is that i dont know which approach to take. I am plannin to make it as follows: "ANALYSES" table - consisting of "name", "ID" of analyses "PROBES" table - consisiting of "name", "ID", "reference", "VALUE", "measurement". Also the PROBES will have the field which links it to certain "ANALYSES" instance. SO it will be like "ANALYSES #1" -> "PROBE1", "PROBE2", "PROBE3" "ANALYSES #2" -> "PROBE1", "PROBE3" And so on. The operator should be capable of adding new analyses and adding probes to this analyses via frontend in one "view" - like "LAB settings" and in another view - to enter values to instances of this analyses (all analyses instances will be linked to some "VISIT" - the service case) What approach should i take planning the app and models? will it be some Meta classes or just multiple tables linked "manytoone" or "manytomany"? Will be gratefull for any advice! -

Annotate new field with the same name as existing one
We are facing a situation here that I would like to get more experienced user’s opinion. We are at Django 4, Python 3.9. The current scenario: We already have our system running in production for a reasonable time and we need to change on the Backend some returned data to our Frontend application (Web, mobile…) based on users choice. Something important is: Changes on the Frontend side are not an option for now. We need to override some attributes from one model, based on existing or not corresponding data on another table. The Tables (Django Models): AgentSearch (this data is replaced every single day by an ETL process) id identifier_number (unique) member_first_name member_last_name member_email some_other_attrbs Agent (Optional data that the agent can define) id agent_search_identifier_number (FK OneToOne) first_name last_name email For our requirement now, all the queryset will be made starting on AgentSearch. The idea is getting the Agent data instead of AgentSearch data every time there is an agent linked to it. Today we get like this: AgentSearch.objects.all() I know that would be easier to annotate new columns like this: # using a different attribute name NEW_member_first_name=Case( When( agent__id__isnull=True, then=F("member_first_name"), ), default=F("agent__first_name"), ), This would require us to make … -
Django Rest How I can Get all values from model Serializer each separately

restrict signup with django-allauth
I'm thinking of using Django allauth for user athentication/authorization but am a bit puzzled about how you prevent or screen initial signup. I'm envisioning a small group of maybe 50 users (and I would have a list of these). I see nothing about allauth allowing you to check against my personal list of people who should be allowed access. Is allauth even a good solution in this scenario? Just to reiterate, my concern is not about using, say, Google to verify their email / identity, but rather pre-screening the people who can sign up in the first place. -
Problem with CSS styling in a html page in Django
So, i am literarily one week into learning web development and i'm following this Django tutorial, i got the index page that i swiped from online to compile properly with it's static elements also. Ran the "python3 manage.py collectstatic" command and everything. So now i'm linking a registration page which i setup up as a new app in the project and when i try and put the css styling file it doesn't work. i've tried just puting in the same directory as the html templates, then i've moved it to styles and rerun the earlier python command so it's also present in assets, also made use of the "{% static 'abcde.css' %}" as well as {% load static %} in the register.html (only did it in the index initially) and i'm still having no luck with styling the page, any help would be appreciated -
django: override admin/login with custom loginview and authenticationform but same template
I added an expiry date field to my User. Now I want to add a custom error message to a failed login if the account is expired, because if I only override the ModelBackend's can_authenticate method, the form throws the standard validation error which suggests that the problem resides with the credentials. I prefer clarity. So I extended AuthenticationForm and overwrote its confirm_login_allowed method to do an expiry check and raise a ValidationError with a newly added error message. However, I get complaints from Django that the template does not exist: TemplateDoesNotExist at /admin/login/ registration/login.html urls.py from django.contrib.auth import views as auth_views from my_app.auth.forms import AuthForm urlpatterns = [ # path("admin/", admin.site.urls), # Have to comment out or the next item will not match re_path(r"^admin/login/$", auth_views.LoginView.as_view(form_class=AuthForm), name="login"), re_path(r"^logout/$", auth_views.LogoutView, name="logout"), ... ] my_app/auth/forms.py from django.contrib.auth.forms import AuthenticationForm from django.core.exceptions import ValidationError class AuthForm(AuthenticationForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.error_messages["account_expired"] = "This account has expired." def confirm_login_allowed(self, user): super().confirm_login_allowed(user) if user.expired: raise ValidationError(self.error_messages["account_expired"], code="inactive") -

django update password for User not working

I don't know why, I think I did everything, but for some reason after I update the password and get redirected to the reverse_url if I try logging out and in, the new password doesn't work. I don't know what's causing this issue or in what file, so it's hard to troubleshoot. -

Media volume inaccessible to Celery using Docker
I'm dockerizing a Django app and I'm having quite some trouble with it. I have the Django app using postgres as well as nginx and gunicorn successfully settled. However, when dockerizing Celery, it seems that it doesn't have access to my media files. I've been looking for the reason for a few hours, but nothing came up. The only thing I saw that I found strange was that my media volume seems to be empty when checking on Docker desktop, but I don't even know if that's the way it should or not... I've tried different approaches on the definition of the media volume in my Celery container but to no avail. Here is my docker-compose.yml: version: '3.8' services: rabbitmq3: container_name: rabbitmq image: rabbitmq:3-alpine ports: - 5672:5672 postgres: container_name: postgres hostname: postgres image: postgres:latest env_file: - env environment: - POSTGRES_USER=postgres - POSTGRES_PASSWORD=ThisPasswordShouldBeChanged19456 - POSTGRES_DB=Scripts Application ports: - "5432:5432" restart: on-failure volumes: - postgresql-data:/var/lib/postgresql/data django_gunicorn: container_name: django_gunicorn volumes: - media:/media env_file: - env build: context: . ports: - "8000:8000" command: sh -c "python manage.py migrate && python manage.py collectstatic --no-input && gunicorn main.wsgi:application --bind 0.0.0.0:8000" depends_on: - postgres nginx: container_name: nginx build: ./nginx volumes: - .:/code - static:/static ports: - "80:80" …
