Subpages created via admin disappears in menu
I'm creating subpages using admin panel. Then I'm using loop to add them to main menu. They are displayed only on home page. If I switch to one of them they no longer show up in menu (same happen with languages prefixes). so lets say we have home.html with menu: home | about | createdsubpage1 | createdsubpage2 | EN | DE | PL then I go to 'createdsubpage1' or any other page and in menu left only: home | about some views: def index(request, *args, **kwargs): multilanguage = Multilanguage.objects.all() sub_links = Subpage.objects.all() return render(request, 'home.html', {'multilanguage':multilanguage, 'sub_links':sub_links}) def generated_page(request, slug): unique_subpage = get_object_or_404(Subpage, slug=slug) sub = Subpage.objects.get(slug=slug) if sub.is_active: context = { 'unique_subpage': unique_subpage, } return render(request, 'subpage.html', context) else: return render(request, '404.html', {'sub':sub}) app url: urlpatterns = [ path('', views.index, name='index'), path('o-nas', views.about, name='about'), path('oferta', views.offer, name='offer'), path('kontakt', views.contact, name='contact'), path('subpage', views.subpage, name='subpage'), path('<slug:slug>', views.generated_page, name='generated_page'), ] header.html: <ul id="nav-mobile" class="right hide-on-med-and-down"> <li><a href="{% url 'index' %}">{% trans 'Strona główna' %}</a></li> <li><a href="{% url 'offer' %}">{% trans 'Oferta' %}</a></li> <li><a href="{% url 'about' %}">{% trans 'O Nas' %}</a></li> {% for sub in sub_links %} {% if sub.is_active %} <li><a href="{% url 'generated_page' sub.slug %}">{% trans sub.title %}</a></li> {% endif … -

"Back button" problem with AJAX form post on a multi-page site
In my Django project I have a page with a table of devices and a form to add a new device. And now I want to translate that form post to AJAX. I've done this with a help of jQuery Form Plugin (http://malsup.github.com/jquery.form.js): $('#deviceAddForm').ajaxForm({ dataType: 'json', async: true, cache: false, success: function (data) { device_row = '<tr>' + '<td>' + data['name'] + '</td>' + '<td>' + data['description'] + '</td>' + '</tr>'; $(device_row).hide().appendTo($('#deviceTableBody')).show("slow") } }); And now I have a browser "back button" problem. If a user posts some devices, goes to different site and then back (through browser back button) additional AJAX content is not displayed. This problem is usual to AJAX, and all of the solutions, that I've found refer to History API. When AJAX content is updated there should be history.pushState call, and browser back/forward buttons should be handled through window.onpopstate event. Maybe I am missing something, but this way seems to work only if a user travels only on one particular single page application site (SPA). If a user goes, for example, to Google and back onpopstate event will not fire (HTML5 History API: "popstate" not called when navigating back from another page). So this doesn't seem … -
Django Updating A one To Many Array
So I get this error Direct assignment to the reverse side of a related set is prohibited. Use emails.set() instead. This is how my code looks like class Client(models.Model): class Email(models.Model): client = models.ForeignKey(Client, on_delete=models.CASCADE, related_name='emails', null=True, blank=True) email = models.CharField(null=True, blank=True, max_length=50) class EmailSerializer(serializers.ModelSerializer): class Meta: model = Emailfields = '__all__' class ClientSerializer(serializers.ModelSerializer): emails = EmailSerializer(required=False, allow_null=True, many=True) def update(self, instance, validated_data): # Update all fields of Client. [setattr(instance, k, v) for k, v in validated_data.items()] instance.save() return instance So the client can have many emails. When update is called, it says Direct assignment to the reverse side of a related set is prohibited. Use emails.set() instead. This error message can be avoided by removing the emails from the validated_data via let emailsData = validated_data.pop('emails', []). but once done, im not sure what to do next in order to update the emails array if it needs updating, or deleting it if it is not in the emailsData array anymore. Thoughts? -
How to save a qr code image as a model field in Django

Should I divide a table by OneToOneField if the number of columns is too many?
I have a student model that already has too many fields including the name, nationality, address, language, travel history, etc of the student. It is as below: class Student(Model): user = OneToOneField(CustomUser, on_delete=CASCADE) # Two many other fields A student has much more information I store in other tables with a OneToOne relationship with the student model such as: class StudentIelts(Model): student = OneToOneField(Student, on_delete=CASCADE) has_ielts = BooleanField(default=False,) # 8 other fields for IELTS including the scores and the date and file field for uploading the IELTS result # I have other models for Toefl, GMAT, GRE, etc that # are related to the student model in the same manner through a OneToOne relationship Should I merge the tables into one table or the current database schema is good? The reason I chose this schema was that I was not comfortable working with a table with two many columns. The point is that for every student, there should be a table for IELTS and other models and, as a result, the number of rows in Student table is the same as the number of rows in the IELTS table, as an example. -

How to Make username field case insensitive in Dnago? Is my Implementation right?
I am in starting of my web project using Django and Django Rest Framework. I wanted my username field to be case Insensitive and hence I searched web about how to achieve it and got to this beautiful blog: https://simpleisbetterthancomplex.com/tutorial/2017/02/06/how-to-implement-case-insensitive-username.html. He suggested this method: from django.contrib.auth.models import AbstractUser, UserManager class CustomUserManager(UserManager): def get_by_natural_key(self, username): case_insensitive_username_field = '{}__iexact'.format(self.model.USERNAME_FIELD) return self.get(**{case_insensitive_username_field: username}) class CustomUser(AbstractUser): objects = CustomUserManager() for models.py But when I wrote tests, they were failing because User.objects.get_by_natural_key was returning two user objects when I created two users with same username, but different case (ex: 'aniket' and 'Aniket'). So, I got through this approach : from django.contrib.auth.models import UserManager, AbstractUser # Create your models here. class CustomUserManager(UserManager): def create_user(self, username, email=None, password=None, **extra_fields): return super().create_user(username.lower(),email,password,**extra_fields) def create_superuser(self, username, email, password, **extra_fields): return super().create_superuser(username.lower(),email,password,**extra_fields) def get_by_natural_key(self, username): case_insensitive_username_field = '{}__iexact'.format(self.model.USERNAME_FIELD) return self.get(**{case_insensitive_username_field: username}) class User(AbstractUser): objects = CustomUserManager() So, is this approach up to the mark? -
Manually displaying formset forms as a table in Django

Django: Accessing variables in class-based views
I'm setting up a website with a fairly basic users system where you can do the usual stuff like login, change your password etc. I'm using an example Django project and changing it a bit here and there. When the user is logged in I am able to access the user's email address and put it into the page by adding this to the template {{ request.user.email }}. But in a link emailed to user to reset their password where the user is not logged in the same thing doesn't work. I'm guessing it must be possible to access it somehow though. This is the class view that I'm using: class RestorePasswordConfirmView(PasswordResetConfirmView): template_name = 'accounts/restore_password_confirm.html' def form_valid(self, form): form.save() messages.success(self.request, _('Your password has been set. You may go ahead and log in now.')) return redirect('/') def get_context_data(self, **kwargs): context = super(RestorePasswordConfirmView, self).get_context_data(**kwargs) context = {**context, **host_(self.request)} return context Is there any way to access the user.email variable? -

django a particular view is getting triggered twice (GET/POST) both and only in chrome, firefox and postman requests trigger the view just once.W
get requests are javascript redirects just by changing window.location.href and post requests are ajax requests, same url in django url conf serves the two of them. The page is heavily populated with data, images and links etc. which do come as a response in get and post requests. On Chrome it executes the request twice, I cannot see it going twice in the Network tab on dev tools but at the terminal where I am running server I can see the view's print statements executing twice. I could have kept it fine like this, but then the first request goes with parameters and the second goes without the parameters(data to post) and the resultant page is always from the second request which is not exactly what the user is asking for.
