Django showing incorrect url but displaying the correct content
I am having an issue with some Django code; I have a form at mysite/edit_home, which updates some content which will be displayed on the index page at the root of mysite/. When the form correctly submits, it renders the index template, and all content is correctly displayed, but the url does not change, and instead shows /mysite/edit_home still despite showing a different page. I'm wondering if there's any reason why this will not change? I have tried to remove as much information from the below as it is a pretty large site already so don't want to clutter the issue. There are no issues other than this across all the other pages and databasing, etc, and this issue only is showing the wrong url and does not affect the content of the page. Thanks for all the help. I have tried most combinations of changing urls files, and changing the method of rendering, ie using a reverse etc but it won't say anything besides /mysite/edit_home rather than /mysite/ or /. Below is the code: mysite/project/urls.py urlpatterns = [ path('mysite/', include('mysite.urls')), path('admin/', admin.site.urls), path('', views.index, name='index') ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) mysite/urls.py from django.urls import path ... app_name = 'mysite' urlpatterns … -
countdown timer Django
need to implement a timer with the following idea: the user has a form to submit their data to the Answer database, which is handled by the QuizTake class. This class contains views that perform various functions such as validation, user authentication, data submission to the server, and data saving. The functionality you want to implement is as follows: create a countdown function where, while the timer is running, the answer submission form is enabled and the user can use it. When the timer expires, the form saves its content and forcefully saves it to the Answer database, and input into the form is no longer accessible. How can this be implemented? view class QuizTake(FormView): form_class = QuestionForm template_name = 'cansole/question.html' result_template_name = 'result.html' single_complete_template_name = 'single_complete.html' timer_duration = 3600 def dispatch(self, request, *args, **kwargs): self.quiz = get_object_or_404(Quiz, url=self.kwargs['quiz_name']) if self.quiz.draft and not request.user.has_perm('quiz.change_quiz'): raise PermissionDenied self.logged_in_user = self.request.user.is_authenticated if self.logged_in_user: self.sitting = Sitting.objects.user_sitting(request.user, self.quiz) else: self.sitting = self.anon_load_sitting() ##сделать редирект на логин if self.sitting is False: return render(request, self.single_complete_template_name) self.start_time = datetime.now() self.timer_expired = False return super().dispatch(request, *args, **kwargs) def check_timer_expired(self): elapsed_time = (datetime.now() - self.start_time).total_seconds() return elapsed_time >= self.timer_duration def get_form(self, *args, **kwargs): if self.logged_in_user: self.question = self.sitting.get_first_question() … -
<a> tag concatonates current url to href value in django
Im building an app where users can enter their twitter, fb and ig account links to their profiles. After they have submitted these urls to the profile form my django app save them to db and later on these values should be populated in the profile page as tags as such. <div class="gap-3 mt-3 icons d-flex flex-row justify-content-center align-items-center"> {% if object.twitter_link %} <a href="{{ object.twitter_link }}"><span><i class="fa fa-twitter"></i></span></a> {% endif %} {% if object.fb_link %} <a href="{{ object.fb_link }}"><span><i class="fa fa-facebook-f"></i></span></a> {% endif %} {% if object.ig_link %} <a href="{{ object.ig_link }}"><span><i class="fa fa-instagram"></i></span></a> {% endif %} </div> I noticed that the tag values are not the same as in the href attribute. For example these are the actual values of the href attribute and the corresponding tag values. {{ object.twitter_link }} = 'weeeee' --> https://currentpageurl.com/weeeee {{ object.fb_link }} = 'www.facebook.com' --> https://currentpageurl.com/www.facebook.com {{ object.ig_link }} = 'https://www.instagram.com/instagram/' --> https://www.instagram.com/instagram/ The tag generated the value that is inside href attribute only in case when the link had an https prefix. In all other cases it concatenated the current page url with the value inside the href attribute. How can I avoid this behaviour and make the tag show only … -

How to remove trailing slash in the URL for API created using Django Rest Framework
I have created a django web-app and created rest apis for the same. Here is the project structure main_project | |___api | |___product this is the urls.py in the main_project. urlpatterns = [ path("admin/", admin.site.urls), path("api/v1/", include("api.urls")) ] There is urls.py inside the api folder like this urlpatterns = [ path("product/", include("api.product.urls"))] Now inside the product folder I have created a urls.py file urlpatterns = [ path("<str:id>", ProductView.as_view(), name="product") ] Now when I run these apis on Postman I do get a trailing slash and the urls look like this localhost:8000/api/v1/product/xyz123 also when I have to query something the urls look like this localhost:8000/api/v1/product/?sorting_field_name = product_name/ Now as per the convention this is an incorrect way of naming urls, I want to remove those unnecessary trailing slashes. How do I solve this? -

Why can't I use inspectdb command with terms table in Django project?
I'm trying to create a model for terms table in models.py file using inspectdb command in Django project. The terms table contains information about students and their GPA for three grades. I'm using Oracle 18 database and Django 3.2. When I try to execute this command: python3 manage.py inspectdb terms > models.py I get this message: Unable to inspect table 'terms' The error was: 'STU_ID' I don't know what is the error with STU_ID column, it exists in the database and has a valid data type and constraints. I tried to use --exclude option to exclude the column from inspection, but it didn't work. I got this message: manage.py inspectdb: error: unrecognized arguments: --exclude I also tried to use --table-filter option to inspect only terms table, but it also didn't work. I got the same message: manage.py inspectdb: error: unrecognized arguments: --table-filter I don't understand why these options are not available in Django 3.2, they are mentioned in the official documentation. Is there a solution for this problem? How can I create a model for terms table in models.py file? Thank you. -

Django Model Validation: How to validate a model field based on the field value of an instance of a different model?
Background: I have a model Bid that implements "bids" on a specific instance of a Listing model. When a Bid is created, the current_bid field is set through a ModelForm and I want to validate that the current_bid field set via the ModelFormfor that Bid is greater than the current_bid field previously set for the Listing instance the Bid is being created for. For reference, here are the two models I have created in Models.py: from django.conf import settings from django.contrib.auth.models import AbstractUser from django.db import models from django.core.validators import MinValueValidator, DecimalValidator from decimal import Decimal from django.core.exceptions import ValidationError class User(AbstractUser): pass class Listing(models.Model): CATEGORY_CHOICES = [ ("APPAREL", "Apparel"), ("COLLECTIBLES", "Collectibles"), ("COMICS", "Comics"), ("MEMORABILIA", "Sports Memorabilia"), ("SNEAKERS", "Sneakers"), ("TRADING_CARDS", "Trading Cards"), ("OTHER", "Other") ] CONDITION_CHOICES = [ ("BRAND_NEW", "Brand New"), ("NEW_DEFECTS", "New with Defects"), ("LIKE_NEW", "Like New"), ("Good", "Good"), ("LIGHTLY_USED", "Lightly Used"), ("USED", "Used"), ("POOR", "Poor") ] author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="usernames") title = models.CharField(max_length=80) description = models.CharField(max_length=800) starting_bid = models.DecimalField(max_digits=11, decimal_places=2,validators=[MinValueValidator(Decimal('0.00'))]) current_bid = models.DecimalField(default=0, max_digits=11, decimal_places=2,validators=[MinValueValidator(Decimal('0.00'))]) image = models.URLField(blank=True) category = models.CharField(max_length=40, choices=CATEGORY_CHOICES, blank=True) condition = models.CharField(max_length=40, choices=CONDITION_CHOICES, default="Brand New") def __str__(self): return f"{self.title}" class Bid(models.Model): owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="owners") listing = models.ForeignKey(Listing, on_delete=models.CASCADE, related_name="listings") current_bid = … -

Django - want to use inspectdb to get only one table. Using MS SQL Server
I've been testing the inspectdb with django 4.0. If I do "python manage.py inspectdb --database MSDatabase", it tries to bring all table info into the model. Is there a way to select only few or one tables? The DB server is MS SQL Server. The database is MSDatabase, the schema is MySchema, and the table name is MYTBL. I tried "python manage.py inspectdb --database MSDatabase MYTBL" and got the table not found error.
