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? -
Always empty aggregations django elasticsearch

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 … -

Django giving 500 instead of 404 for unknown URLs when debug is false
Django = 2.1.x Python = 3.7.x If Debug is True - it returns a 404. If Debug is False - it gives a 500 error.

Multiple Apps in play , something similar to multiple apps in django

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. But how do i set the form field dynamically? -

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 to properly render a field from a database in a page without refreshing?
I am trying to display a User's name on top of a box where they enter their Employee # in a form, without having to refresh the page, for example, they enter their # and then after they click/tab onto the next field, it renders the name on top, so the user knows they've entered the correct info. This name is also stored in a separate model, so I try to retrieve it using the "id/number". I am not too familiar with AJAX but after reading a few similar questions it seems like an AJAX request would be the most appropriate way to achieve this. I tried to make a function get_employee_name that returns the name of the person based on the way I saw another ajax request worked, but I'm not sure how to implement this so it displays after the # is entered. models.py class EmployeeWorkAreaLog(TimeStampedModel, SoftDeleteModel, models.Model): 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, blank=True) def __str__(self): return self.employee_number This is the model where the name is stored alldata/models.py class Salesman(models.Model): slsmn_name = models.CharField(max_length=25) id = models.IntegerField(db_column='number', primary_key=True) forms.py class WarehouseForm(AppsModelForm): class Meta: model = … -

There are some similar questions I found like this: https://serverfault.com/questions/453296/how-do-i-validate-an-rsa-ssh-public-key-file-id-rsa-pub But they use ssh-keygen, which needs a saved file to read from. What would be a more elegant way to implement this in python? -
How to choose model fields to be displayed in the generic ListView
I would like to create a table using some of the model fields names. As you can see below, model has defined 8 fields but I just want to display on the table 3 of them. After you click on the contractor name in the table you will be forward to the detail view where you will see all the models fields. I don't want to hardcode the table column names. So how can I display only these 3 model fields in the table? views.py class ListView(generic.ListView): model = Contractor template_name = 'contractors/list.html' context_object_name = "all_contractors" fields = ['company_name', 'email', 'website'] models.py class Contractor(models.Model): company_name = models.CharField(max_length=200) phone_number = models.CharField(max_length=50) email = models.EmailField() website = models.URLField() city = models.CharField(max_length=100) street = models.CharField(max_length=100) postal_code = models.CharField(max_length=50) notes = models.TextField() def __str__(self): return self.company_name -
