Python/Django: How to make sure "string".upper and "string".lower work with different languages?
I have a problem with upper and lower functions in Python/Django. I have the following line of code: UserInfo.objects.get(id=user_id).city.upper() The problem is that some of the Turkish users let me know that they are seeing the wrong information. For example one of them is from a city called "izmir". The upper function converts that into "IZMIR" it turns out the actual result should be "İZMİR". What is the right way to use upper or lower functions for any given language? I read about changing the server locale as an answer. Changing server locale for each user request does not make sense to me. What about multi-threaded applications that handle different users simultaneously? Thanks in advance for your time. -

Can I install Django Rest Framework in an uploaded website in pythonanywhere?
Summary: I decided to use python for my thesis I started my project while simultaneously studying about python and django I've added a lot of contents, models, and apps in my project, and I just now realized that I need to create a Content Management System, and somebody told me to use Django Rest Framework. I started searching on how to use it, and everything that I saw installed it before creating the project, and it might be too late for me because I might have a lot of errors that I might not be able to trace.(or maybe django rest framework should really be installed before starting) Can someone tell me if its possible to just install it? Or a hint/tip for alternatives? I only have less than 2 weeks left before my defense. Thank you for the help and understanding, Im new sorry -

Django and accessing POST data from forms.Form
For some reason, this form appears to only be able to POST the 'email' parameter.

Django setUp class only execute once
I am currently following a django tutorial (https://youtu.be/UqSJCVePEWU?t=8655) and he uses the setUp function to make test cases. I did the same thing as him and I get an error that the username is not UNIQUE self.c = Client() User.objects.create(username='admin') Category.objects.create(name='django', slug='django') self.data1 = Product.objects.create(category_id=1, title='django beginners', created_by_id=1, slug='django-beginners', price='19.99', image='django') def test_url_allowed_hosts(self): response = self.c.get('/') self.assertEqual(response.status_code, 200) def test_product_detail_url(self): response = self.c.get(reverse('store:product_detail', args=['django-beginners'])) self.assertEqual(response.status_code, 200) so, after some hours I found that setUp is executed for every test (which does not create any problem in the tutorial) and I changed my function to @classmethod def setUpClass(self): which solves the problem, but now I don't know if I messed something up and the tutorial should work, or something in django has changed since then. Any help is appreciated and if any files or something is needed I'll provide them. Thank you in advance -
