override __str__ method that allow display conditionnal string based on browser language
I have a Django project that is internationalized I have a model Pays that contain 2 fields (french and english) to manage translation In my form, I have a ModelChoice Field that display a list of country in french How can I manage language in Pays model str method ? def __str__(self): return f"{self.pay_nom_eng}" ... self.language = request.session.get('language') PAYS = Pays.objects.filter(pay_ran = 1).order_by('pay_ide') ... self.fields["pay_ide"] = forms.ModelChoiceField(queryset = PAYS, label = _("Country"), widget = forms.Select) -
Django static file href incorrectly formatted
So I have the following static loading in Django with DEBUG=True: {% load static %} <link rel="stylesheet" href="{% static 'css/styles.css' %}"> Now in my settings.py I have the following: STATIC_URL = "/static/" When I run the server python manage.py runserver and inspect my webpage in the console, the sources appear correctly, but the href attribute points to /static/css/styles.css, rather than static/css/styles.css (notice the omission of the leading /). Notice that the href on line 18 points to the wrong folder, but static/css appears correctly in the sources. So, clearly django, behind the scenes, just replaces {% static 'css/styles.css' %} with STATIC_URL + 'css/styles.css'. If I now change STATIC_URL to STATIC_URL = "static/" The href is correct (points to the right file) but the files themselves are not present!! So in order for the css file to appear, STATIC_URL needs to be /static/, but the href references a non-existent directory. If I change STATIC_URL to static/ the href is correct, but the files don't appear! Does anyone know how to fix this? I feel like it's such a basic problem, but it's doing my head in... -

django login not redirecting to index
I have got a login screen, which upon successful authentication should show user details on the same base URL , it used to work just fine all these days, and all of a sudden it's throwing 302 response code HTTP POST /login/ 302 [0.60, 127.0.0.1:53864] when the correct username and password is entered, no redirection is initiated, it forever keeps loading. What's more strange is that when I reload the same tab or open a new tab, it is correctly logged in and shows the appropriate details. No changes related to login functionality were made, the only recent change I made was to add reset password functionality which had nothing to do with this. user_login def user_login(request): field = None if request.method == "POST": username = request.POST.get('username') password = request.POST.get('password') user = authenticate(username=username,password=password) try: field = UserModel.objects.get(user__username=username) if user: if user.is_active: login(request,user) return HttpResponseRedirect(reverse('index')) else: messages.error(request,'username or password not correct') return HttpResponseRedirect('../') else: print("Error logging in{}".format(password)) messages.error(request,'Invalid username/password combination') return HttpResponseRedirect('../') except Exception: #return HttpResponse("ACCOUNT NOT ACTIVE!!!") messages.error(request,'Entered username does not belong to any account') return HttpResponseRedirect('../') else: return render(request,'app/login.html',{}) urls.py urlpatterns = [ path('admin/', admin.site.urls), url(r'^$',views.IndexView.as_view(),name='index'), url(r'login/',views.user_login,name='login'),] It was working without any problems all these days, not sure of … -

Will this QuerySet hit database twice or once?

Performance issue with Django and Postgres on a single update
I have an intermittent performance issue with Django and Postgres when updating a single line in a small "< 1m" rows table. The APM reports the issue on the update line, which is: Model.objects.filter(id=model_id).update(field=True) The error is raised because the execution takes more than 5s. This code runs in a celery task which receives the id of the model as the argument and executes normally most of the time. I know it's a very open question but any idea or help on what might be happening is appreciated. I'm running out Python 3.7, Django 2.0.13, and Postgres 9.5. -

Keep selected options after form submit in Django

Computional complexity of reversed Foreign Key reference [closed]
I got such models in Django: class Artist(models.Model): name = models.CharField(max_length=128) class Sons(models.Model): title = models.CharField(max_length=128) artist = models.ForeignKey(Artist, on_delete=models.DO_NOTHING) Let's say there are 1000 songs in total, while Artist1 has just 10 songs. When I do basic ORM query like Artist.objects.first().songs.all(), does it need to check every of 1000 songs if it is related to the Artist1 or it "knows" which 10 to get? In other words, does the cost of retrieving those 10 songs increase as the next songs get created? -
How to save an image to a customized filepath in django admin?
I am trying to upload images to specific folders I select. the model code is as below: class PhotosTags(models.Model): Tag_name = models.CharField('Tag Name', max_length=100, default='NA', unique=True) Description = models.TextField('Tag Description', max_length=200, blank=True) class Meta: verbose_name = 'Tags' verbose_name_plural = verbose_name ordering = ['Date_created'] def __str__(self): return str(self.Tag_name) class Photos(models.Model): Name = models.TextField('Photo Name', max_length=200, blank=True) Tag = models.ForeignKey(PhotosTags, on_delete=models.CASCADE, default=None) filepath = 'Gallery' Photo = models.ImageField(upload_to=filepath, blank=False) class Meta: verbose_name = 'Photos' verbose_name_plural = verbose_name ordering = ['Date_uploaded'] pre_save.connect(upload_photo, sender=Photos) Here each tag has its own folder. The function I want to realize is, when I upload an image, I can select a specific tag (through selection of "Tag") and then this image can be uploaded to that folder. I tried use: signals to change the filepath but failed. The code i wrote is: def upload_photo(sender, instance, **kwargs): tardir = instance.Tag.Tag_name instance.filepath = 'Gallery'+'/'+tardir -
Package and deploy a Django app on local server
I am creating a web app using Django. I want to be able to package it into a setup file that can be installed on a client's computer and run on a local server on one computer or maybe a company's server which will serve the app to multiple pcs. I do not want to serve the app directly via internet as the data it will use is highly confidential. The client should not have access to the source code. The app will use multiple python modules other than Django. I am relatively new to programming so please keep it simple as far as possible. -

How to just listen to specific ip addresses for calling specific views
I was wondering if there is a way to listen to ip addresses and judge thereby if a view is allowed to be displayed or not. If so, could you recommend me a good approach for this. I'm gonna give an example in order to get better understood. from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('core.urls')), path('accounts/', include('accounts.urls')), ] As to this example, when a certain url pattern is matched, i want for django to check if the requesting pc ip address lies in 'allowed_ips_list'. Im aware of this can be attained inside views but, i was thinking that if i am able to optimize this process it would be better.. than calling a view and checking consecutively. As always, thank you for your attention. -

How to get year-month costs summary for certain category in DetailView, Django?
I have a table with expenses categories and when I click on the certain category it redirects me to this DetailView page. Then I want to show the year-month costs summary for chosen category to look similiar to this what I already got (summary per year-month but not for certain category). How can I achieve that? This is what I got for now and got stucked: def category_summary(): summary_by_year_month = Expense.objects.annotate( month=TruncMonth('date')).values('date').annotate( amount=Sum('amount')).order_by() return summary_by_year_month MODELS.PY class Category(models.Model): name = models.CharField(max_length=50, unique=True) def __str__(self): return f'{self.name}' class Expense(models.Model): class Meta: ordering = ('date', '-pk') category = models.ForeignKey(Category, null=True, blank=True, on_delete=models.CASCADE) name = models.CharField(max_length=50) amount = models.DecimalField(max_digits=8, decimal_places=2) date = models.DateField(default=datetime.date.today, db_index=True) def __str__(self): return f'{self.date} {self.name} {self.amount}' The most confusing part about this problem for me is how can I retrieve this information only for chosen category and show it to user in DetailView? Thank you in advance for any help. -

Unable to override both contrib.admin.AdminSite and django.contrib.auth.admin.UserAdmin simultaneously
I'm trying to both override the default AdminSite class, and the UserAdmin. I'm trying to combine the examples from two different sections of the documentation: Overriding the default admin site Extending the existing User model Originally I had just the overriden AdminSite class, but then the problem arose when I tried to also override UserAdmin.
