Can I modify a widget/field so that it is filtered further in Django/Python?
I have a form with a field in my models called employee_number, which is tied to another model, called Salesman, which holds all the data with all the employee names, numbers, dept, etc. Currently it works by only allowing submission of the form if the employee number entered is is salesman. What I'm trying to do is also filter it so that only employees that are part of team "MM" and "OM" and whose employee_status is "A" are the only ones able to submit. forms.py class WarehouseForm(AppsModelForm): class Meta: model = EmployeeWorkAreaLog widgets = { 'employee_number': ForeignKeyRawIdWidget(EmployeeWorkAreaLog._meta.get_field('employee_number').remote_field, site, attrs={'id':'employee_number_field'}), } fields = ('employee_number', 'work_area', 'station_number') models.py class EmployeeWorkAreaLog(TimeStampedModel, SoftDeleteModel, models.Model): employee_name = models.CharField(max_length=25) employee_number = models.ForeignKey(Salesman, on_delete=models.SET_NULL, help_text="Employee #", null=True, blank=False) work_area = models.ForeignKey(WorkArea, on_delete=models.SET_NULL, null=True, blank=False) station_number = models.ForeignKey(StationNumber, on_delete=models.SET_NULL, null=True) def __str__(self): return self.employee_number alldata/models.py class Salesman(models.Model): id = models.IntegerField(db_column='number', primary_key=True) team = models.CharField(max_length=2) employee_status = models.CharField(max_length=1, blank=True) -

I want to know, what is the best efficient way to give each user a subdomain? I've seen these topics: Link1 and Link2 but these are too old (10 years ago). Is there any better way? -

Formset validation not working - receiving KeyError
I am trying my first formset and stuck on validation. I have combined a normal form ProgramSelector with a formset. Everything works so far in terms of saving the data but validation is giving me a real headache. I am simply not understanding how this part works. How do I get this to display errors in the forms like it normally would? Right now I am getting KeyError 'headline' and the ProgramSelector clean() doesn't seem to be doing anything.

Is there a way to remove directories along with removing media files in Django?
As far as I know, it's quite simple to remove a media file when calling the delete() method. However, I'd like to ask if there's also a way to remove the path that the media file was located.

sys.exit() in django web application
While debugging a django application codebase I came across some pieces of code as below: try: ...some business logic... except Exception as e: logging.exception(...) sys.exit() I am not able to understand how this web API would behave in case of an exception? Our web app has more than 1 worker which I understand, are modeled as differed processes by django. Per sys.exit documentation, the process will only exit if called from the main thread. How would this behave when there are multiple workers and the workers spawn multiple threads? Does django replace the worker process with another process if the worker's main thread encountered sys.exit and the worker process was shut down? Is it even a good idea to have sys.exit in an exception block or anywhere in the app for that matter? -

How to filter/get second to last most recent record to update a field in Django?
I have a model that keeps track of enter/leave times. I am trying to add constraints to make the data more accurate. Currently, when someone "Enters", it creates a record, saves the time in timestamp and then redirects. If the person then tries to enter again, it creates a new record with a new timestamp. What I'm trying to add now is that, if the person has a previous entry without an exit timestamp then that record (which would be the second to last most recent entry), would be flagged by updating the time_exceptions field to 'N'. Currently, it changes all the fields to 'N', regardless of whether there's an exit or not, as shown below. class EnterExitArea(CreateView): model = EmployeeWorkAreaLog template_name = "operations/enter_exit_area.html" form_class = WarehouseForm def form_valid(self, form): emp_num = form.cleaned_data['employee_number'] area = form.cleaned_data['work_area'] station = form.cleaned_data['station_number'] if 'enter_area' in self.request.POST: form.save() EmployeeWorkAreaLog.objects.filter((Q(employee_number=emp_num) & Q(work_area=area) & Q(time_out__isnull=True) & Q(time_in__isnull=True)) & (Q(station_number=station) | Q(station_number__isnull=True))).update(time_in=datetime.now()) if EmployeeWorkAreaLog.objects.filter(Q(employee_number=emp_num)).count() > 1: EmployeeWorkAreaLog.objects.filter((Q(employee_number=emp_num) & Q(work_area=area) & Q(time_out__isnull=True)) & (Q(station_number=station) | Q(station_number__isnull=True))).update(time_exceptions='N') return HttpResponseRedirect(self.request.path_info) I tried the following, but I get a expected string or bytes-like object and while it still creates a new record before crashing, it does not update the time_exceptions of … -

Import Statements Inside Functions in Python
I have been trying to solve (in my own way) the problem of making configurations sane and 12-factor compliant for a Django app I am working on. The following was my idea. As you can see, I wanted to fully isolate the specification of environment to, well, environment. Prior to this, I had to re-specify the entry-level settings file inside the manage.py for each new environment, despite already having separate settings files for each environment. settings.py (to which manage.py would point) import environ env = environ.Env() environ.Env.read_env() DJANGO_ENV = env('DJANGO_ENV') def production(): import production def development(): from .development import * def testing(): import testing def staging(): import staging options = {'production': production, 'development': development, 'testing': testing, 'staging': staging} print(options[DJANGO_ENV]()) However, I got complaints (errors) from Python 3.7 that import statements are only allowed at the module level. My question is two-fold: how sane is this approach overall and is there a way to do imports at the function level? -

How to dynamically set value to MoneyField in djmoney?
Currently i am using djmoney to store money info in my database. Right now i need to manually set values in my form, so i use class MyForm(forms.Form): money = MoneyField() ... def view(request): form = MyForm(initial={ 'money' : Money(0.5, 'USD')}) But that's not working, because, as I later found out, MoneyField uses default_amount and default_currency kwargs to set it.

Here is my code views.py def search(request): if request.method == 'GET': try: q = request.GET.get('search_box', None) posts = Listing.objects.filter(title__contains=q, is_live=1) | \ Listing.objects.filter(street_address__contains=q, is_live=1) | \ Listing.objects.filter(city__contains=q, is_live=1) | \ Listing.objects.filter(state=q, is_live=1) | \ Listing.objects.filter(property_class__contains=q, is_live=1) | \ Listing.objects.filter(sale_or_lease__contains=q, is_live=1) return render_to_response('search/results.html', {'posts': posts, 'q': q}) except KeyError: return redirect('home') results.html: <div class="container" style="width:20%; float:right; text-align:center; overflow:auto;"> {% for Listing in posts %} <a href="{% url 'post_view' Listing.pk %}"><img style="width: 384px; height: 216px;" alt="Thumbnail" src="{{ MEDIA_URL }}{{ Listing.thumbnail }}"/></a> <p style="color:black;">{{ Listing.title }}</p> <p style="color:black;">Sale or Lease: {{ Listing.sale_or_lease }}</p> <p style="color:black;">Class: {{ Listing.property_class }}</p> <p style="color:black;">Square Feet: {{ Listing.square_feet }}</p> {% if Listing.price %} <p style="color:black;">Price: ${{ Listing.price|linebreaksbr }}</p> {% endif %} {% if Listing.price_per_square_foot_per_year %} <p style="color:black;">Price per SqFt/yr: ${{ Listing.price_per_square_foot_per_year|linebreaksbr }}</p> {% endif %} <p style="color:black;"> City: {{ Listing.city }}, {{ Listing.state }}</p> <hr> {% endfor %} </div> For the above code, Listing.thumbnail is not being output, only the placeholder text is. Here is an example of code I have that is working. views.py def preview(request, pk): posts = Listing.objects.all().filter(is_live=1) preview = get_object_or_404(Listing, pk=pk) attorneys = Attorneys.objects.all().filter(state=preview.state) | \ Attorneys.objects.all().filter(city=preview.city) lenders = Lenders.objects.all().filter(state=preview.state) | \ Lenders.objects.all().filter(city=preview.city) developers = Developers.objects.all().filter(state=preview.state) | \ Developers.objects.all().filter(city=preview.city) context = {'posts': posts, 'preview': … -

Django forms : Edit image field (delete and show existing)
I am trying to have a Django Model form with an image field but I have the two problems: I don't know how to show the current name of the image in the input I don't know how to provide a way to remove the image forms: class CityLogoForm(forms.ModelForm): logo = forms.ImageField(widget=forms.FileInput(attrs={'class': 'custom-file-input'}), required=False) class Meta: model = City fields = ['logo'] views: def management_form_general(request, city_slug): city = City.objects.get(slug=city_slug) if request.method == 'POST': logo_form = CityLogoForm(request.POST, request.FILES, instance=city) if logo_form.is_valid(): logo_form.save() else: logo_form = CityLogoForm(instance=city) return render(request, 'management/form/city_general.html', {'city': city, 'logo_form': logo_form}) html: <form action="" enctype="multipart/form-data" method="post"> <div class="form-group row"> <label for="id_city" class="col-sm-2 col-form-label form_title">{{ logo_form.logo.label }}</label> <div class="custom-file"> {{ logo_form.logo }} <label class="custom-file-label" for="{{ logo_form.logo.id_for_label }}" data-browse="Choisir Image">{{ logo_form.logo.label }}</label> </div> </div> </form> I have a script changing the label when the user is uploading something but I cannot find a way to get the current value for the image fields (for the normal ones it's properly prepopulated). As it seems to not prepopulate the input, it seems to be ignoring when the input is empty and therefore never deletes the current logo. -
Django template inheritance // how to use multiple css files?
I would like to find a solution to have multiple CSS files for different templates using Django template inheritance. So far I could extend my base.html template with another apps template. Now I would like to use a seperate css files for the apps html templates (one app = 1x html, 1x js, 1x css). But when I include the template into the template tag it replaces the css file from the base.html and crashes the site. How can someone implement a second css file into a extended html template that only refers to the extended part and doesn't "touch" the base.html? Thank you for your guidance in advance. extended html template which crashes site because of replacement of base.css file: {% extends 'templates/base.html' %} {% load static %} {% block head_css_site %} <link href="{% static 'Quotes_app.css' %}" rel="stylesheet" type="text/css"> {% endblock head_css_site %} {% block content %} <h1>Test</h1> {% endblock %} {% block footer_javascript_site %} <script src="{% static 'Quotes_app.js' %}"></script> {% endblock footer_javascript_site %} base.html: {# HTML5 declaration #} <!DOCTYPE html> {% load static %} <html> {# Make modifiable head elements #} <head> <title>{% block title %} {% endblock title %} DASHEX </title> {% block head_favicon %} <link rel="icon" …
