Is there any way to limit the choices displaying in autocomplete fields in Django admin based on the foreign key just selected in another field?
I encounter a problem when using the autocomplete fields in Django admin. #model.py class Party(models.Model): pass class Address(models.Model): party = models.ManyToManyField(Party,through='MailAddress') class MailAddress(models.Model): party = models.ForeignKey(Party,on_delete=models.CASCADE) address = models.ForeignKey(Address,on_delete=models.CASCADE) class Mail(models.Model): party = models.ForeignKey(Party,on_delete=models.CASCADE) mail_list = models.ForeignKey(MailAddress,on_delete=models.CASCADE) #admin.py class AddressInline(admin.TabularInline): model = Address.party.through class PartyAdmin(admin.ModelAdmin): inlines = [AddressInline] class MailAddressAdmin(admin.ModelAdmin): search_fields = ['address'] class MailAdmin(admin.ModelAdmin): autocomplete_fields = ['mail_list'] My question is whether I can make the autocomplete field display MailAddress field for the selected Party only?

How to return a form result set using MySQL in PhpMyAdmin to a Python Web Application
Apologies for the novice MySQL question, I need some guidance. I am working on a project with several Python/Django programmers building a web app. The web app uses MySQL database on the backend, and I access it using XAMPP and PhpMyAdmin. We need to create several reports for the web app, to be displayed in the web page and available to print. These reports are generally in table format. I wanted to develop a stored procedure to return a table resultset, based on the parameters entered in the developers forms, but I am hitting a wall finding resources on writing this out. Is this not possible? Can a MySQL stored procedure, or other function, return a table as a result set? Is there a way I could do this with a temp table or views instead? If not, then can anyone advise on an alternative to complete these reports, please. Thank you for any feedback you can provide on this topic, in advance! -

I am new to Django and still a beginner at Python. The tutorial I'm following is here: https://docs.djangoproject.com/en/3.1/intro/reusable-apps/#installing-reusable-apps-prerequisites I am trying to follow the Django tutorials but it was not very clear where exactly I should be placing my /django-polls/ folder when removing /polls/ from /mysite/.

I dont know how to pass two queryset parameters into one URL
I really struggled to explain my problem and the only way I found it would be possible is - through screenshots as I have a lot of code and I am not sure what is really needed here. So if you want any code, tell me I will add. The numbers on the pictures indicate the order. Choosing the category Selecting the category it redirects me to - /products_list?category=(that category_id) Filtering through brand in that category Now please pay attention to the URL and what happens after I have chosen the brand I want to filter with. Back on the first page Problem is here: Now I am back on the first page, where are all the products but I wanted it to stay on that URL where are that kind of category products. What I wanted to happen? Instead of it taking me to the page where are ALL the products and then doing the filtering, I want it to stay on that category page and return the filtered products there. The brand dropdown menu also should only show that category products that I am in, not all. -

Is Django model ordering also an indexing?
Per the Django docs, ordering is "The default ordering for the object, for use when obtaining lists of objects". This is great, but I don't see anything about indexing the database with this ordering. Does Django add an index with this ordering as well? Or should I add indexes under ordering as well? That just seems redundant though. -
