How to mitigate the slow function in Django view
My Django website is in shared server ( nginx with uwsgi & Sqlite). The database is huge, when users search for certain model instances, it slows down the server as it wait for the query to finish. VIEW.PY def Newssearch(request): if request.method == "POST": searchdata = request.POST.get('searchdata') result = News.objects.filter(titleEnglish__icontains=searchdata)[0:8] return render(request, 'newsfront/searchresult.html',{'news':result}) The server (Pythonanywhere.com) seems to not support async functions. Any idea how to reduce the priority of the above function , so that if multiple types frequent requests come, it gives less priority to the search function. -

preserve data while making changes to fields of model in django
I have two models which are Contact and UpdateInfo. Update model is a foreignkey relationship with Contact like below: class Contacts(models.Model): full_name = models.CharField(max_length=100, blank=True) notes = RichTextField(blank=True) /............./ class UpdateInfo(models.Model): contacts = models.ForeignKey(Contacts,on_delete=models.CASCADE, related_name='update_info') updated_at = models.DateTimeField(auto_now=True) modified_by = models.CharField(max_length=100, blank=True) Now what I need is to put the notes field into UpdateInfo model and remove from Contacts model. Because now the businees requirement has changed and what they need is they need to add notes in the existing notes and want to see them who added the notes and when they added it with the notes appended. But the problem is if I remove the notes field from Contacts and add it to Updateinfo model , there are many data into the production and the notes field data will be lost. Now how can we run migrate in such a way that I add notes field into the Updatinfo model and also migrating the data at the same time.?? Is this what is done by dev ops or we should do it?? Because usually dev ops are migrating the data to the production server from staging area. I need expert opinion on this. -

Django: set-cookie causes cookies to be stored in the backend instead of the frontend
example.com is frontend (Next.js) api.example.com is backend (Django) For some reason, the cookie is stored on the backend domain. This does not allow the front-end to access the stored cookies. I have implemented an authentication API using the following, but as far as I can tell, there is no setting to change the domain where cookies are stored. django-cors-headers dj-rest-auth djangorestframework-simplejwt CORS_ALLOWED_ORIGINS = ['https://example.com'] CORS_ALLOW_CREDENTIALS = True How can I store cookies on the front-end domain? -
CSS and Bootstrap only working on one html page and not the other
I launched my app on Heroku and everything seems to be working as usual except that the design (css) is only fully working on my home.html page but not my results.html page. On the results.html page it seems that only some css components are working while others are not. I've attached pictures of the design differences as well as the header code where I link my css and bootstrap. I would appreciate any help in knowing why my results.html page is not fully loading the css file. home.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <!-- jquery --> <script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" crossorigin="anonymous"></script> <!-- Drag and drop script --> <script src="{% static 'PRIIIME_Travel/js/drag_drop.js' %}"></script> <!-- Get value of ranking boxes script --> <script src="{% static 'PRIIIME_Travel/js/get_value.js' %}"></script> <!-- Meta tags --> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="robots" content="noindex, nofollow"> <link rel="icon" type="image/png" href="{% static 'logo/PRIIIME_Logo.png' %}" /> <!-- Bootstrap --> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous"> <!--- Include CSS --> <link rel="stylesheet" href="{% static 'PRIIIME_Travel/css/home.css' %}" type="text/css" /> <title>Travel</title> </head> results.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <!-- jquery --> <script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" crossorigin="anonymous"></script> <!-- Drag and drop script --> <script src="{% … -
