Django URL Pattern Syntax - raw string
So this might sound like a newb question but I was just wondering what is the difference between path('index/', views... And... path(r'^index/$', views... I just wrote my first web app and I use the first example but I see everyone using the raw string syntax in examples I look up. Are there any differences between the way django handles the two examples? Thanks in advance. -

Django. How to return error 500 without sending mail to admins
I am using standard error handling in production - if there are server errors I am getting mails. However, on certain APIs I want to have a response with HTTP code 500 or 502 as part of the "valid flow". (It's done for educational purposes) So my view for that looks like this: from rest_framework.response import Response from rest_framework import status def give_me_error(request): return Response("This is expected error", status=status.HTTP_500_INTERNAL_SERVER_ERROR) And what I want is not to get email of this particular response (because I wanted it to be 500) I've also tried this way: from django.http import JsonResponse def give_me_error(request): return JsonResponse({'error': 'expected error'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) But it also generates mail. Is there a way to have a view returning error 500 that will not trigger e-mail send? (without disabling the e-mail functionality system-wide) Per Django documentation: https://docs.djangoproject.com/en/4.0/howto/error-reporting/ When DEBUG is False, Django will email the users listed in the ADMINS setting whenever your code raises an unhandled exception and results in an internal server error (strictly speaking, for any response with an HTTP status code of 500 or greater) -
Django Pytest. Use database entries in parametrize
I want to have a test for data that will use real data from DB. The goal is to go through all the entries of a table Foo and apply some test logic on each entry. Ideally is to use parametrize for that but I am a bit struggling with DB access to parametrize. What I do so far: tests.py import pytest from app.models import Foo pytestmark = pytest.mark.django_db @pytest.fixture(scope='session') def django_db_setup(): settings.DATABASES['default'] = { 'ENGINE': 'django.db.backends.mysql', 'NAME': os.environ['DB_NAME'], 'USER': os.environ['DB_USER'], 'PASSWORD': os.environ['DB_PASSWORD'], 'HOST': 'localhost', } @pytest.mark.django_db class TestFoo: @pytest.mark.parametrize('foo', Foo.objects.all()) def test_foo_objects(self, foo): assert foo.is_ok Eventually I get E RuntimeError: Database access not allowed, use the "django_db" mark, or the "db" or "transactional_db" fixtures to enable it. However, if DB-access is not used in parametrize - it works. I.e inside test_foo_objects DB-access is allowed. So the question is how to allow parametrize use DB as well? -

How can I simplify retrieval of corresponding foreign key objects
I use Django on the backend and React on the frontend. I have quotes that are related to a character by foreign key, for example: class Quotes(models.Model): quote = models.CharField(max_length=1000, unique=True, null=True, blank=False) quote_ja = models.CharField(max_length=1000, unique=True, null=True, blank=True) quote_by = models.ForeignKey(Characters, on_delete=models.SET_NULL, null=True, blank=True) quote_from = models.ForeignKey(Media, on_delete=models.SET_NULL, null=True, blank=True) date_added = models.DateField(auto_now=True) I have some models with multiple foreign keys, for example in the above, quote_by returns the keys to the corresponding characters. image of the foreign keys in api This is the Characters Model connected to quote_by: class Characters(models.Model): first_name = models.CharField(max_length=100, null=True, blank=False) last_name = models.CharField(max_length=100, null=True, blank=True) ja_name = models.CharField(max_length=100, null=True, blank=True) image = models.ImageField(upload_to='characters/', null=True, blank=True) I would like to access the data from fields such as quote_by/quote_from with React. At the moment it seems overly complicated and I'm wondering if I should make a change to the backend. -

In my Django site I want to show a table. Because of I can't show all table rows in one page I am using pagination. But every time I go to other page my tables size and buttons positions is changing. How can I fix their size and positions same on every page? This is the view I using: class TableView(ExportMixin, SingleTableView): model = MyModel table_class = MyTable template_name = 'table_list.html' context_object_name = 'table_list' paginate_by = 8 My html page: <div class="container"> <h1>Table</h1> <span class="current"> <h3>Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}.</h3> </span> {% if page_obj.has_previous %} <a id="left-arrow" href="?page={{ page_obj.previous_page_number }}">PREVİOUS</a> {% else %} <div class="current"> <a id="left-arrow" href="#">PREVİOUS</a> </div> {% endif %} {% if page_obj.has_next %} <a id="right-arrow" href="?page={{ page_obj.next_page_number }}">NEXT</a> {% endif %} <table class="table" border=1 id="mytable"> <thead> <tr> <th>Name</th> <th>Age</th> <th>School</th> <th>Email</th> <th>Note</th> </tr> </thead> <tbody> {% for customer in customers %} <tr> <td>{{table_list.name}}</td> <td>{{table_list.age}}</td> <td>{{table_list.school}}</td> <td>{{table_list.email}}</td> <td>{{table_list.note}}</td> </tr> {% endfor %} </tbody> </table> </div> </div> -
Link to detailpage of object with todays date from navbar
In my application, I have objects that are connected to each day. The object's date must be unique. I want to include a link to the detailpage of the object of today from the navbar. However, I don't know how this should be implemented. Because essentially, I need to be able to get the pk of todays object from the navbar template. This is how I try to link to it right now in my navbar.html file: <a class="nav-link" href="{% url 'today' object.pk %}">Today</a> This is the url for the detail view: path('today/<int:pk>', TodaysView.as_view(), name='today') Is there anyway I could filter the dates inside of the template? -

How to pass a value to a Bootstrap modal in Django
I'm trying to implement a feature where I get to change a product by passing its id to a modal and change it there, then reflect the changes in the same page, where the user can click on the product name, a modal page appears with the product name and a list of products, then he can change the product from the list of products, click save changes, the modal page closes, and the product is now updated. The problem is that I was facing difficulty in passing the product id to the modal div that exist in the same template, but couldn't figure it out, then I saw Martín De la Fuente's approach and tried it, but it didn't work with me as well. It shows me this error message: django.urls.exceptions.NoReverseMatch: Reverse for 'products_modal' not found. 'products_modal' is not a valid view function or pattern name. My code is as the following: In product template: Sending product id to the product_modal template: <td> <a href="#" class="open-modal" data-url="{% url 'products_modal' product.id %}"><span>{{product.name}}</span></a> </td> Creating an empty div to insert the product_modal in it: <div id="product-modal-div"></div> Javascript part: <script> var productModalDiv=$("#product-modal-div") $(".open-modal").on("click",function(){ $.ajax({ url:$(this).attr("data-url"), success:function(data){ productModalDiv.html(data); $("#ProductModal").modal(); } }) }) </script> … -
Reverse for 'Tools' with no arguments not found. 1 pattern(s) tried: ['home/(?P<category>[^/]+)\\Z']
Based on an answer to my previous question here This is my html code: <a href="{% url 'Tools' %}"><p>Tools</p></a> When I used category like this def home( request,category) in my views, I got a positional argument error so I used this : def home( request,**kwargs ): p=product.objects.filter(category__name= category) return render(request,'home.html',{'p':p}) This is URLs: urlpatterns = [ path('',views.home), path('home/<str:category>', views.home,name='Tools'), ] But after going to this URL http://127.0.0.1:8000/home/Tools I got this error : NoReverseMatch at /home/Tools Reverse for 'Tools' with no arguments not found. 1 pattern(s) tried: ['home/(?P<category>[^/]+)\\Z'] Why do I get this error? Or how can I solve this error home() missing 1 required positional argument: 'category' if I want to use this : def home( request,category)?
