I want to embed user_id on the url path
Below I have a photo to help understand better. I have tried different ways to achieve this particular problem, but it has not been achieved till now. I want to embed the user_id on the url of the page, which can be used for tracking for later uses. In the picture, the whole page has been taken screenshot. It has url of the page, username of the current user, product id (which can be seen on the url as well as in the product details part). user_id in the database saves the id of the current user who has added the product. The datatype of user_id in the database is integer datatype and has user_ids ad : 1,2(currently I am working with one superuser and one active user) Below are the files. URLS: urlpatterns = [ path('', views.blink_network), # redirect to root - path path('blink_network/', views.blink_network, name='blink_network'), path('AddNewProduct/', views.AddNewProduct, name='AddNewProduct'), path('blink_viewproduct/', views.showproduct), path('blink_viewproduct/', views.blink_viewproduct, name='blink_viewproduct'), path('affiliation/<int:pk>/update', AffProductUpdateView.as_view(), name='affproduct-update'), path('affiliation/<int:pk>/delete', AffProductDeleteView.as_view(), name='affproduct-delete'), path('link/', views.link, name='link'), path('link/<int:uid>/', views.link_view, name='link_view') ]+static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) VIEWS. #Display only single-user products def showproduct(request): if request.user.is_authenticated: current_user = request.user# define current user result = AffProduct.objects.filter(user=request.user) return render(request, 'blink_viewproduct.html', {'result': result}) def link(request): if request.user.is_authenticated: current_user = request.user# define … -
How do I call a specific field in a model into another model?
I am new to django. I wanted to know if it was possible to call a specific field in a model into another model. The goal is to update a the quantity of a specific product in the database and generate a receipt for it. Here's the example: models.py: class Product(models.Model): name = models.CharField(max_length=300, null=True) price = models.FloatField(null=True) quantity = models.IntegerField(default='0', blank=True, null=True) class UpdateStock(models.Model): date = models.DateTimeField(default=timezone.now) wayBill_Number = models.CharField(max_length=300, null=True) product_Name = models.ForeignKey(Product.name, null=True, on_delete= models.SET_NULL) quantity = models.ForeignKey(Product.quantity, null=True, on_delete= models.SET_NULL) I just want to select the product and the quantity to update in the database but I am unable to do so. -
How to restrict django endpoint to localnetwork?
In my project, I use many FastAPI microservices to conduct the specified tasks and a Django app to handle user actions, connect with the front-end, etc. In Django database I store information about the file paths that a microservice should obtain. I want to provide it to a microservice and this microservice only. So I want to restrict access to the endpoint to a specified port on the local network. Other endpoints should be normally available for the web app. Using just Django cors headers will not work since I want access to most of the endpoints normally and restrict it to localhost for only a tiny subset. CORS_ORIGIN_WHITELIST = [ "http://my_frontend_app" # most of the endpoints available from the front end "http://localhost:9877", #the microservice that I want to provide with the path ] Another solution might be to use from corsheaders.signals import check_request_enabled, but in the use cases that I have seen, it was usually used to broaden the access , not to restrict it (front-end should not have access to the subset of endpoints). I’m not sure whether it is a good solution. # myapp/handlers.py from corsheaders.signals import check_request_enabled def cors_allow_particular_urls(sender, request, **kwargs): return request.path.startswith('/public-api/') check_request_enabled.connect(cors_allow_mysites) Is there … -

Using period symbol after django-admin startproject <projectname>
I have been following two different tutorials about the Django framework and in one of the frameworks, I entered the following commands: django-admin startproject mysite . In this command, the author specifically asked to enter a period after the command. The following pic is the structure of the folder created:https://i.stack.imgur.com/q3Cab.png In the second tutorial which is on the official Django website, I used the following command: django-admin startproject mysite In this command, I did not use a period in the end and the folder structure is as follows: https://i.stack.imgur.com/aI50z.png. You can clearly see from both the images that one has a single mysite folder with 4 other .py modules inside it, whereas in the other there is another mysite folder inside the mysite folder. Can anyone please explain why there is this difference and which is better for use? -
Speed Optimization in Django
I am building a Blog App and I am also thinking to implement video posts in it. I am trying to optimize the speed of the Web App in Development and also in Production. I have deployed many sites build in Django in last several months on PythonAnywhere. I've noticed that most of site contains simple functionalities like :- Create, Edit, Image Upload, ListView, DetailView of Blogs , etc. With 500 to 600 lines of Code (python). Talking about Development :- When i open a page that contains 100 to 150 Blogs with Images, then it is taking 2 to 3 seconds to open the page AND then i think this may be Because of more blogs and queries then I checked the page's queries and query's Time using Django-Debug-Toolbar then I deleted all the posts except 1 post after that I saw in debug-toolbar, it is showing Total time to load the Page is 600ms. 4 queries in 6 to 8ms I removed some queries but still same results. I also searched about it then i found a Post of optimizing queries using select_related then I also used it BUT I didn't see any much improvement. I used to … -

Django rest framework authtoken.views.obtain_auth_token returns ' "detail": "Method \"GET\" not allowed."
projectapp/urls.py from django.urls import path from rest_framework.authtoken.views import obtain_auth_token urlpatterns = [ path('token/', obtain_auth_token), ] So when I try to call this using POSTMAN when it's running locally (using runserver) it returns the token and works correctly, but after deploying on cloud using Nginx on Emperor mode (Using POSTMAN to call the API), it returns' { "detail": "Method \"GET\" not allowed." } This was also discussed in here. So basically my client was not sending a POST request. So I read some docs and discussions and found out that when POSTMAN receives a 301 or 302 on POST request, it tries again with GET. So i ran curl on the server with my username and password, it did return a 301, <html> <head><title>301 Moved Permanently</title></head> <body> <center><h1>301 Moved Permanently</h1></center> <hr><center>nginx/1.18.0 (Ubuntu)</center> </body> </html> So my question is, Why is it working in my local server and not in production?

how to make dependent model, from one model to another model in Django
I have 3 models and I want to make all of them depend on each other. I have seen this website, and this is a dependent drop-down list in the same HTML template but I have each new HTML page for each model. So, I have one common field in all the models is code. where code field contains a number of codes like eg.: DD1, DD2, DD3, and so on. So, this code is been there for all three models for eg.: Model motor contains the code field, and in the code field there is code like DD1, DD2, DD3, and also in the drum model contain the code field which is DD1, DD2, DD3 and all the three models have same code field and have matching code. So, now I want to make all three models depend on each other with the help of code. Basically, if the user chooses the motor product which having code as DD4 then if the user goes to another page so the user has to get the DD4 code product from other models. I have done coding like this: views.py def addProductMotor(request): user = request.user motor_id = request.GET.get('motor_id') motor_cart = Motor.objects.get(id=motor_id) Cart(user=user, … -
Django change values() dynamically for each record

How to set nested related fields serializers in Djando Rest Framework?

Here is my views.py. from django.shortcuts import render, redirect from .models import Todo from .forms import TodoForm from django.views.decorators.http import require_http_methods def index(request): return render(request, 'home.html') def todoPanel(request): form = TodoForm() todo_list = Todo.objects.order_by('id') context = {'form': form, 'tasks': todo_list} return render(request, 'todo_panel.html', context) @require_http_methods def addTask(request): form = TodoForm(request.POST) if form.is_valid(): task = Todo(task=form.cleaned_data['task']) task.save() return redirect('panel') Here is my urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='home'), path('panel/', views.todoPanel, name='panel'), path('addTask', views.addTask, name='addTask') #path('delete_confirm', views.todo_delete, name='delete_confirm') ] and here is my todo_panel.HTML {% extends 'base.html' %} {% block content %} <h1>Todo Panel</h1> <!-- Render the form here--> <form action="{% url 'addTask' %}" method="POST"> {% csrf_token %} {{ form }} <input type="submit" value="Add"> </form> <!-- Display the todos here --> <ul class="list-group"> {% for task in tasks %} <li class="list-group-item">{{ task }}</li> {% endfor %} </ul> {% endblock content %} I don't want django to redirect me to addTask... I want it to make a POST request. I read the example here https://github.com/PrettyPrinted/django_todo_app and he was able to do it without it redirecting to add. I just want it to make a POST request so it can POST a todo to database. -
Should I Use uWSGI?
