Failed template inheritance in django templating
I am in a middle of a project. The project uses basic html at the frontend. I having trouble in template inheritance. This is the basic code : - {% extends 'main.html' %} {% block content %} <h2>Home</h4> <hr> {% if request.user.is_authenticated %} {% block home %}{% endblock home %} {% else %} {% for doc in doctor %} <div> <small>Doctors around</small> <br> <a href="{% url 'profile' doc.user.id %}"><li>{{doc.user.name}}</li></a> <br> </div> {% endfor %} {% endif %} {% endblock content %} Also the code is extended to another template. The child page is :- {% extends 'rec/home.html' %} {% block home %} <div> {% if request.user.usertype == 'p' %} <h1>Hi {{request.user.name}} </h1> {% else %} <h1>Hi {{request.user.name}} </h1> {% endif %} </div> {% endblock home %} Both the files are in the same directory. But i have defined the templates dir in settings file in a different directory. -
How Do I Improve A Huge Many-To-Many Django Query To Improve Django Speed?
I have a query set like this that I need to optimize because I think this query set slows down the website performance. The user_wishlist field is a many-to-many DB relational relationship to an Account model/table. How do I? product_wishlist_store_list = [] non_paged_products = Product.objects.prefetch_related('user_wishlist').select_related('category').filter(is_available=True).order_by('created_date') for product in non_paged_products.iterator(): # Get User Wishlist try: product_wishlist = product.user_wishlist.filter(id=request.user.id).exists() if product_wishlist: product_wishlist_store_list.append(product.id) except ObjectDoesNotExist: pass So when I turn on the log for a DEBUG purpose in Django, I see that there are nearly a thousand (0.000) SELECT queries of INNER JOIN. Does the 0.000 mean there is no hit to the database or is it? Still, seeing a thousand queries like that kind of scary to me -- I feel this code is so inefficient. Is it? -

I am trying to create authentication system in Django. My code is failing to authenticate the user

Django Redirect for All Pages
I have multiple pages in my Django project. Here's my urls.py urlpatterns = [ path('page1', views.page1), path('page2', views.page2), path('page3', views.page3), ] I want to add a redirect that applies to all the pages so that users that aren't authenticated will be redirected to MSOAuth2. Here's my views.py def page1(request): return render(request, "page1.html") def page2(request): return render(request, "page2.html") def page3(request): return render(request, "page3.html") def MS_OAuth2(request): if not request.user.is_authenticated: return redirect('https://login.microsoftonline.com/tenant/oauth2/v2.0/authorize?') What regex or url pattern do I need to use so all my pages can redirect to views.MS_OAuth2? This is what I have so far but it's not working. I want the redirect to apply to all pages in my website. urlpatterns = [ path('page1', views.page1), path('page2', views.page2), path('page3', views.page3), path(r'^$', views.MS_OAuth2) ] Thank you! -
Can I control the order of Cascade Deletes in Django?
I have models like this: class Parent(models.Model): pass class Child(models.Model): parent = models.ForeignKey(Parent, on_delete=models.CASCADE) class Log(models.Model): parent = models.ForeignKey(Parent, on_delete=models.CASCADE) detail = models.TextField() I also have a signal like this: @receiver(post_delete, sender=Child) def handle_delete_child(sender, instance, **kwargs): log = Log(parent = instance.parent, detail="child deleted") log.save() Now, if I try to delete the parent, I can see with debug on that the steps are going like this: Delete parent's logs. Delete parent's children (causing new log to be written as per the signal). Try to delete parent, but fails with "Cannot delete or update a parent row: a foreign key constraint fails", I think on the log created in step 2. If I was able to specify that #2 should happen before #1, I think that would solve the problem, but I cannot find any reference to such things in the docs. Even a creative solution like a new signal or a model method override would be welcome. -

Use a SQL function in the FROM clause with the Django ORM
I need to convert the following SQL into a Django ORM query but cannot find a way to pull it off. It involves using a SQL function in the FROM clause. In this case, it's a JSONB function that will put the key/value pairs of the json field into separate columns. survey.answers is a JSONB field. The underlying database is postgres. SELECT s.id, jsonb_each_text.key, jsonb_each_text.value FROM survey as s, jsonb_each_text(s.answers); -

Django admin prefetch related on property
I have models Merchant and PhoneNumber. PhoneNumber has a foreign key to Merchant, and Merchant has property business_phone_number which fetches the first phone number in the set of the phone numbers. In Django admin, for the Merchant model, I have business_phone_number in list_display. Although I've put prefetch_related(phonenumber_set), it still queries PhoneNumber 100 times. What am I doing wrong? Here's the simplified code: class PhoneNumber(models.Model): ... merchant = models.ForeignKey("merchant.Merchant", on_delete=models.SET_NULL, null=True, blank=True) ... class Merchant(models.Model): ... ... @property def business_phone_number(self): number = self.phonenumber_set.first() if number: return number.phone_number return None and then in Django admin I have: @admin.register(Merchant) class MerchantAdmin(admin.ModelAdmin): list_display = ("name", "business_phone_number", ...) ... I've put in get_queryset: def get_queryset(self, request): return super().get_queryset(request).prefetch_related("phonenumber_set")... -

Implement Unit Test for OAuth Flow in Django app
I integrated OAuth into my Django app. OAuth has 2 steps: Redirect to OAuth provider domain name Callback to Django app with token I would like to implement TestCase units for the above flow. Here is what I wrote for testing step 1: def test_connect_with_oauth_provider(self): """Test connecting with OAuth provider.""" url = signin_url("oauth-provider") res = self.client.get(url) self.assertEqual(res.status_code, status.HTTP_200_OK) However, the test uses testcase domain not my real domain and thus the test fails. Can you please help me implement tests for both steps? Thanks! -

How to create property methods in django models dynamically?
I am creating property methods for every model where the model attribute includes ImageField or FileField. So, I decided to make an abstract model where I check the fields in the model and if there are any ImageField and FileField in the model the property method creates it automatically by itself. I usually add '_url' to the attribute when I create the method Below is what I do usually class MyModel(models.Model): image = ImageField(...) file = FileField(...) ... @property def image_url(self): if self.image and hasattr(self.image, 'url'): return self.image.url @property def file_url(self): if self.file and hasattr(self.file, 'url'): return self.file.url ... Below what I did so far class MyModel(models.Model): ... def __new__(cls, value): fields = self._meta.get_fields() for field in fields: if isinstance(field, ImageField) or isinstance(field, FileField): ??? Any suggestions? -
Best way to handle temporary user-uploads in web-development?
Hello on the overflow, I am fairly new to web development so please don't crucify me. I am currently in the process of laying out the foundation for a web-app (using Django as backend) that will involve user uploads (blob-files). The application will perform some machine learning on the upload and present the output to the user in the browser. Once presented with the output, the user will have the option to save the upload to that particular user's subfolder in the bucket (assuming cloud storage will be used). How do I best deal with the upload while it is temporary, that is, before the user has decided to save it to storage? The above may reveal a crucial misunderstanding of mine in how the user interacts with the server, however, I can see this as one solution: Creating a temporary folder for each user in the bucket, where an upload is stored until the user either decides to save it (move to proper folder) or not to save it (delete it from temporary folder). Is this solution totally bonkers and is there a much easier one? I look forward to any replies. Sincerely, an aspiring web developer -
Static files in django when extending from template

Django model field bug? "value too long for type character varying(3)" error
I am declaring two choice fields for my django model in the same manner but one of them somehow bugs into having maxlength=3. I am using a PostgreSQL database.
