How not to delete default image when new one is uploaded?
I wrote code that deletes old user avatar when user uploads new one. And the problem is that, if user has default avatar and decides to change it, default image gets deleted. Here is my code: @receiver(pre_save, sender=Profile) def delete_file_on_change(sender, instance, **kwargs): if instance.pk: try: old_image = Profile.objects.get(pk=instance.pk).image except Profile.DoesNotExist: return new_image = instance.image if old_image and old_image.url != new_image.url: old_image.delete(save=False) I tried this: @receiver(pre_save, sender=Profile) def delete_file_on_change(sender, instance, **kwargs): if instance.image.url == '/media/default.jpg': ... But it didn't work because print(instance.image.url) for some reason, returns not /media/default.jpg but url of newly uploaded file. Also, here's my view: def update_user(request): if request.method == 'POST': if 'edit_profile' in request.POST: profile_form = UpdateProfileForm(request.POST or None, request.FILES, instance=request.user.profile) if profile_form.is_valid(): profile_form.save() return redirect('editprofile') profile_form = UpdateProfileForm(instance=request.user.profile) context = {'ps_form': password_form, 'u_form': user_info_form, 'pr_form': profile_form} return render(request, 'update_user.html', context=context) -

Best backend framework for web and mobile applications?
My company is redesigning its backend. We are an ecommerce style business that also deals with providers. We need to track the delivery of products like Uber Eats does with food. We also have a complex inventory managing system where we need to know the location and stock available of certain products to guarantee speedy delivery. Additionally we need to be able to plan deliveries at certain dates in the future. All these things and other planned features and improvements make the functionality quite complex. We want to design our architecture as microservices, although we might start with components and REST API's for now and split them up into services in the future. We want to support a web application first but will develop a hybrid mobile app in the near future as well. I want our backend to: Be scalable Be able to split into microservices as we increase in complexity. Support web application. Support a Hybrid mobile app. What backend framework is best suited for these needs? -

Django annotate query with values from Many To Many Relationship
Following the example on Many To Many relationships for Django: https://docs.djangoproject.com/en/3.1/topics/db/examples/many_to_many/ I want to be able to display in the Django Admin a column on the Article listview which contains the title's of associated Publications. So if I have an article a1 which has publications: Publication(title='Pub 1') Publication(title='Pub 2') I want to see a column in the admin listview showing "Pub 1, Pub 2". I could do this with a custom function on the Admin class: class ArticleAdmin(admin.ModelAdmin): list_display = ['publication_titles'] def publication_titles(self, obj): return ', '.join([pub.title for pub in obj.publications.all()]) But that's an N+1 problem: each Article row will execute a query for each associated publication. I see this in the Django debug toolbar, where I see the number of SQL queries executed go from 9 queries to 33 when rendering 24 articles in the listview. I thought maybe I could do prefetch_related in the queryset: class ArticleAdmin(admin.ModelAdmin): list_display = ['publication_titles'] def get_queryset(self, request): queryset = super().get_queryset(request) queryset.prefetch_related('publications') return queryset def publication_titles(self, obj): return ', '.join([pub.title for pub in obj.publications.all()]) But that seems to have no effect on the number of SQL queries executed.

How to return related objects a queryset's values_list instead of just the PKs

The way....what is the shortest way to the correct information
how do programers get access to the correct information without having to ask, like what is the way, Let me give an example, in order to use postgres in Django application, You will have to install something called psycopg2, but in Django-postgres documentation https://docs.djangoproject.com/en/3.1/ref/contrib/postgres/ Theres no such thing as "getting started", theres no mention of psycopg2 at all, u will just have to spend a lot time to google it or watch a video, and if google doesn't have the answer or you just didn't search it correctly, you are stuck, And this is only an example, i have encountered many of these situations, and it's so frustrating, I mean i didn't write postgres and i didn't write django either, i don't know how it works unless someone told me, it doesn't feel like im in control, it's not like a math problem or algorithm where you just have to solve it on your own, but you are in control, The problem is some basic information is just too hard to find in the documentation, the way i do it doesn't seem right, Is everyone else doing it like this? or is there a "smart way" to find it? or … -
