Django/Local Library. How to assign current user to field?
I've started learning Django and im doing a local library. I have a problem. I've created a model Book, which has a borrower. When I want to save current user as a borrower value changes only on page, but not in admin panel. It also changes every single books' value, not just the specific one. class Book(models.Model): title = models.CharField(max_length=100) author = models.CharField(max_length=60) ISBN = models.CharField(max_length=13,unique=True) genre = models.ForeignKey(Gatunek,related_name='Books',on_delete=models.PROTECT) borrower = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True, default='') def __str__(self): return self.nazwa class BookRent(ListView): model = Book template_name = "Books/Book_rent.html" def get_queryset(self): user = self.request.user Book.borrower = user -
Is it possible to customize django.auth error message appropriate for certain registration errors?
I'm trying to display an error message for a certain error that user makes while registering, for now I've only covered an error regarding password and conf_passowrd not matching, but only that scenario works, whenever there is an error regarding, for example, too short password entered, it still displays the error regarding password mismatch.

how to create new tag or select from current tags using Django forms
I have 3 tables, Products, Articles, and tags products and articles both have a "tags" field which has ManyToMany relation with the "tags" table I want to be able to reference multiple tags or create new tags while adding a product or an article (in one field)(using Django forms) for example, "test1" and "test2" are already in the tags table, I want the field to be like this: 1.I type "te" in the tags field 2.A drop down with "test1" and "test2" is opened which I can choose each one of them to be added in the field 3.I type "test3" (which isn't already in the tags table)and hit enter and "test3" is added to the field products and articles both have a "tags" field which has ManyToMany relation with the "tags" table (just like tags in a post in StackOverflow) I think Django built-in forms can handle this but I'm overwhelmed by the documentation and lost in the configuration of my Django forms. what kind of fields and widgets should I use for this purpose? Excuse me if the question is vague I'm new to Django and I would appreciate any kind of help. -
Django UpdateView returns a blank rendered template
I am using django allauth for user authentication, in my adapter I have modified the get_login_redirect_url to redirect new users to an ONBOARD_URL so they can complete registration process while regular users get the expected LOGIN_REDIRECT_URL class UserAccountAdapter(DefaultAccountAdapter): def get_login_redirect_url(self, request): if request.user.is_authenticated and (not request.user.name or not request.user.avatar or not request.user.mobile): url = settings.ONBOARD_URL else: url = settings.LOGIN_REDIRECT_URL return resolve_url(url) I have two functions handling the view and they both inherit from UpdateView and DetailView respectively. class UpdateUserAfterSignupView(LoginRequiredMixin, UpdateView): model = User form_class = UpdateUserAfterSignupForm template_name = 'users/user_form.html' context_object_name = 'user' success_url = reverse_lazy('users:detail') class UserDetailView(LoginRequiredMixin, DetailView): model = User slug_field = 'username' slug_url_kwarg = 'username' template_name = 'users/user_detail.html' context_object_name = 'user' def get_object(self, queryset=None): return get_object_or_404(self.model, username=self.request.user.username) In my DetailView, if i leave out the get_object it returns a PageNotFound 404, but when its present as is, I get a blank page in the rendered template. This is the template: <p>welcome {{user}}</p> <form action="" method="post" enctype="multipart/form-data">{% csrf_token %} {{ form.as_p }} <button type="submit" value="submit">submit</button> </form> and my url conf looks like this [ path('<str:username>/', views.UserDetailView.as_view(), name='detail'), path('complete-signup/', views.UpdateUserAfterSignupView.as_view(), name='complete_signup'), ] Again, all of these results in a blank rendered template, nothing at all.

Dajngo: Get the ID of a clicked button
I am using django. In my views I want to know which button was pressed.

Django template variable not rendering
So I am trying to render a django template variable, but for some reason it is not rendering out. I have the following code: Views.py ... def get_search(request, *args, **kwargs): context = {} context = {"test":"abcde"} return render(request, 'search.html', context) ... Urls.py urlpatterns = [ path("", home_view), path("articles/", include("papers.urls")), path("admin/", admin.site.urls), path("search/", search_view), path("submit/", submit_article_view, name="submit"), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) search.html {extends 'base.html'} {% block content %} <p> {{ test }} hi </p> ... {% endblock %} base.html {% load static %} <!DOCTYPE html> <html> <head> <title>Title</title> <link rel="stylesheet" type ="text/css" href="{% static 'css/stylesheet.css' %}"> </head> <header> {% include 'navbar.html' %} </header> <body> {% block content %} {% endblock %} </body> <footer> {% include 'footer.html' %} </footer> </html> Now, whenever I run the server and go to the search page, everything else gets rendered out, but the {{ test }} doesn't. The 'hi' does get rendered out. I have followed every tutorial and StackOverflow question out there, to no avail. Anyone has any idea what might be going on?

Is there a way in Django to unlock the resources before the transaction is over or to auto restart the transaction if the deadlock is found?
I have a model Orders in my Django rest-framework app. I am retrieving a list of orders based on some filter parameters and at the same time I am also locking orders using select_for_update(). Each order in the Orders model has a status and it could be OPEN, PARTIALLY_COMPLETED, COMPLETED or CANCELLED. However, one of my filter parameters will only consider the order with status OPEN or PARTIALLY_COMPLETED. So the retrieved list will have order with OPEN or PARTIALLY_COMPLETED status only. Furthermore, each order in Orders model also has the parameter units. This represents the units at which the order was created. If the order is in OPEN state then all the units are unsold or if the order is in PARTIALLY_COMPLETED then unsold_units = units - sold_units. Deriving the unsold units for PARTIALLY_COMPLETED orders is done after retrieving the list of orders. Now, let's assume the retrieved order list has 10 order and the total of unsold_units of the list is 1000. However, I just need 100 units so if the unsold_units of the first 3 orders is equal or over 100 units than the remaining orders must be unlocked immediately so that the other transaction can use it. … -
