Make django middleware variables able to handle concurrent requests
I have to implement a custom middleware in django to count the number of requests served so far. It is a part of an assignment that I've got. I have created the middleware like this # myapp/middleware.py from django.utils.deprecation import MiddlewareMixin class RequestCounterMiddleware(MiddlewareMixin): request_count = 0 def process_request(self, request): RequestCounterMiddleware.request_count += 1 def process_response(self, request, response): return response @staticmethod def get_request_count(): return RequestCounterMiddleware.request_count Now my question is how to make the variable request_count able to handle concurrent requests and show the correct value. ChatGPT suggested using threading.Lock(). Would that be a good option? If not, please suggest some other way. Thanks :) -

How to add an i18n locale tag to a Nuxt api proxy?
I am currently working on an app with a Nuxt frontend and a Django backend. The Django backend is localized with i18n. Therefore, the URL contains an i18n tag (example.com/en/). I now want to take this tag from i18n in Nuxt and add it to my proxy in the Nuxt config, which currently looks like this: // https://nuxt.com/docs/api/configuration/nuxt-config export default defineNuxtConfig({ compatibilityDate: '2024-04-03', devtools: { enabled: true }, modules: ['@nuxtjs/tailwindcss', '@nuxtjs/i18n'], nitro: { devProxy: { '/api': { target: `http://127.0.0.1:8000/`, changeOrigin: true, }, }, }, i18n: { locales: ['en', 'de'], defaultLocale: 'en', }, }); The process should be as follows: User with French Nuxt language calls example.com/hello mybackend.com/fr/hello is called via the proxy (/api). If it is Russian, mybackend.com/ru/hello is called. I tried to achieve my goal with a middleware, but could only append the tag. -

How to include a field's display text (i.e., "get_foo_display") in a ModelSchema in django ninja?
Problem Let's say I have a django model with an IntegerField with a defined set of choices and then a django ninja schema and endpoint to update this model.

change_form.html cannot display any drop-down select fields for the ModelForm
I'm working on implementing a drop-down menu for the "add" page of Product_to_Stock_Proxy_Admin function in the Django admin interface. The options for the drop-down menu are from the Distributor model, which is a foreign key for the Product model. The output only shows the drop-down menu itself, and there are no values from the Distributor model, not even the default value "---------". I don't understand why this is happening. Sincerely thank you for your help and suggestions. The reason why I use change_form is because I use Ajax to display other columns immediately when the user fills in the barcode_number. Therefore, I need to implement the drop-down menu on my own. models.py class Product(models.Model): name = models.CharField(max_length=20, blank=True, null=True) distributor = models.ForeignKey('Distributor', on_delete=models.CASCADE) barcode_number = models.CharField(max_length=20, blank=True, null=True) total_amount = models.IntegerField(blank=True, null=True) class Distributor(models.Model): name = models.CharField(max_length=10) admin.py class Product_to_Stock_Proxy_Admin(admin.ModelAdmin): form = Product_to_Stock_Proxy_Form change_form_template = 'admin/change_form.html' fields = ["distributor", "name", "total_amount"] admin/change_form.html This code only displays the drop-down item itself without any options, not even the default value "-------": {% block content %} <form method="post"> {% csrf_token %} {{ form.non_field_errors }} <div class="form-row field-barcode_number"> <div> <div class="flex-container"> <label for="id_barcode_number">條碼號碼：</label> <input type="text" id="id_barcode_number" name="barcode_number" value="{{ form.barcode_number.value }}" /> </div> </div> </div> … -
Angular proxy not working with Django allauth
I have an angular + django project and mostly everything is working. I've setup a proxy.conf as mentioned in the documenation - example here: { "/api": { "target": "http://localhost:8000", "secure": false, "logLevel": "debug", "changeOrigin": true } } but for some reason I cannot make api calls to any django allauth endpoints. The proxy is working because i can make a request to /api/accounts/profile which is a custom view i created to fetch a users information. However, what I'm trying to do is use allauths pre-created endpoints such as /accounts/login or /accounts/logout. If I make a request to http://localhost:4200/accounts/login I get 404 errors that the page/view isn't found. If I remove the domain name so that the proxy kicks in - example: /accounts/login its the same thing. If I change the url to be http://localhost:8000/accounts/login I suddenly get cross origins errors, which means the url is recognized as existing but is not accessable. I have already added all of the cross origins settings to my settings.py and added crf token validation to eliminate some possibilities. Has anyone else experienced this and if so what have you done to fix it? I don't want to create views in Django, that would be … -
