How to implement fool proof Error handling in python-django
I am a newbie and have a question related to error handling in django/python; hoping the pros can provide some directions. In my project, I am sometimes using try/except and other places checking for errors returned from functions. Mostly, all API calls have try/except and then general error handling otherwise. As the project has grown in size, it is becoming quite unwieldy and now it is very hard to ensure that all errors are being properly handled. Especially, with multiple levels of nested functions, it is hard to make sure that I am checking for errors from each function, propagating it properly upstream and handling at every level. I have so far ensured that all APIs have try/except. And I am also checking each function for error handling. My simple question is - is there a defined or recommended way to handle errors? is it possible to really end the program and gracefully exit (after logging the error + stack trace in the log file) in case of certain errors? This is because even if I am handling the error in the function and returning appropriate value, I don't want to rely on the upstream functions properly handling/propagating the error? … -
Adding a Doughnut plot using Vue.js 3 to a Django template
I want to display a Doughnut plot in a Django template using Vue.js 3. The Doughnut plot will be a component because I need to reuse this plot a lot. So far I have managed to create a simple text component in this way: base.html <script src="https://cdn.jsdelivr.net/npm/vue@3/dist/vue.global.prod.js"></script> {% block vue %} {% endblock %} status.html {% extends "../base.html" %} {% load static %} <doughnut-plot title={{title}}></doughnut-plot> {% block vue %} <script type="module" src="{% static 'js/status.js' %}"></script> {% endblock %} status.js import DoughnutPlot from "./components/doughnut_plot.js" const app_status = Vue.createApp({ components: { DoughnutPlot, } }); app_status.mount("#app_status"); doughnut_plot.js export default { props: ['title'], template: `<h4>{{title}}</h4>` }; This code show the correct title that I pass with the context in the corresponding view. However, I cannot manage to change doughnut_plot.js into a plot. I tried the following: status.html % block vue %} <script src="https://cdn.jsdelivr.net/npm/chart.js"></script> <!-- Include Vue Chart.js wrapper --> <script src="https://cdn.jsdelivr.net/npm/vue-chartjs@3"></script> <!-- Include your Vue component script --> <script type="module" src="{% static 'js/components/doughnut_plot.js' %}"></script> <script type="module" src="{% static 'js/status.js' %}"></script> {% endblock %} doughnut-plot.js import { Doughnut } from 'vue-chartjs'; export default { extends: Doughnut, props: ['data', 'options'], mounted() { this.renderChart(this.data, this.options); } }; But I get the error Uncaught TypeError: Failed to resolve … -

Incorrect vps nginx redirect settings for django app
I use vps, ubuntu 20, nginx, gunicorn for run django project. <my_ip>:3000 runs react app, <my_ip>:8000 runs django app. I want run <my_ip> react (frontend), <my_ip>/api/ django (backend) sudo nano /etc/nginx/sites-available/default/: root /home/ubuntu/clinent/build; server { listen 80; server_name <my_ip>; access_log /var/log/nginx/example.log; location /media/ { root /home/ubuntu/api; expires 30d; } location /static/ { root /home/ubuntu/api; expires 30d; } location /api/ { rewrite /api/(.*) /$1 break; proxy_pass http://<my_api>:8000; proxy_set_header Host $server_name; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location / { try files $uri $uri /index.html } } Frontend, backend works fine, static and media works fine.

Django. DJ_REST_AUTH redirects to login page after email confirmation

I use following: settings: ACCOUNT_AUTHENTICATED_LOGIN_REDIRECTS = False ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_USER_MODEL_USERNAME_FIELD = None ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_EMAIL_VERIFICATION = 'mandatory' ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_CONFIRM_EMAIL_ON_GET = True installed apps: APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.sites' 'allauth', 'allauth.account', 'allauth.socialaccount', "rest_framework", "rest_framework.authtoken", "dj_rest_auth", "dj_rest_auth.registration", 'accounts', ] and urls: from django.urls import path, include from dj_rest_auth.registration.views import VerifyEmailView, ConfirmEmailView urlpatterns = [ path("", include("dj_rest_auth.urls")), path( 'signup/account-confirm-email/<str:key>/', ConfirmEmailView.as_view(), name="account_confirm_email", ), path("signup/", include("dj_rest_auth.registration.urls")), path('signup/account-confirm-email/', VerifyEmailView.as_view(), name='account_email_verification_sent'), ] The registration works, I get an email with a link to confirm. I click and it redirects me to login page which as it is REST doesn't exists. I belive that it is allauth responsible for this redirection as I haven't found any settings in dj_rest_auth What I can see in the logs is just: Not Found: /accounts/login/ I expect there to be some way to redirect to page that informs about the result of verification but I can't find anything in the documentation. Do I need to make my own ConfirmEmailView doesn't redirects but returns page with the result? -
DTL tags are not working inside the template script
I am working on a django web application and I need to create a pie graph on dashboard page. I decided to use chart js for this.

Double request logged from node request to Django endpoint
I'm trying to send a POST request to a django endpoint. It fails due to a 405. Inspecting the logs, it appears to receive the POST request, but then immediately followed by a GET request and returns a 405 as this is a POST only endpoint. I've stripped the fetching code back to the following js script: const fetchData = async() => { const response = await fetch("http://localhost:8000/api/auth/user", { method: "POST", body: { test: "test", }, headers: { "Content-Type": "application/x-www-form-urlencoded", }, }); if (!response.ok) { const text = await response.text(); console.log("error", response, text); } const json = await response.json(); console.log("json", json); }; fetchData(); It doesn't seem to matter what endpoint, or what method I send, it always logs a double request. What's also interesting, is if I send a PUT request, it logs a double PUT request, same for GET or even OPTIONS. However, for all POST requests, the second requests is always a GET. Again, it doesn't matter what endpoint I hit! I'm stumped I'm a JS dev, but I have access to the Django code if it would help to post the urls.py or any of the views from there? -

Django Custom Authentication Not Authenticating Users
I have a Django website, what I want is there to be separate user bases, one is User and another is Agent. Now Agent model does not extend the CustomUser Model. So that Agents can register themselves without being registered as a User first. When I register my Agents through AgentRegister form, my Agent passwords are being hashed properly which I can see in my Admin panel. Now the problem is, even when I enter correct Agent credentials in my AgentSignIn form, I can't log in as an Agent as it says "Please enter a correct username and password. Note that both fields may be case-sensitive." Same things happens when I enter correct User credentials into UserSignIn form.

How can I setup a "can visit the link once and only once" kind of permission for my links in django?
I am creating a game webapp using on HTML CSS and Django. There is no JS involved so far because I dont know JS well enough to implement it in my app. I am not a webdeveloper either. I just know python and basic web design. Now to my issue: I have setup various tasks in different levels of the game. the user can visit these task to play them. But they should not be allowed to visit these tasks again after they've played it once. I was think of disabling the link after visiting once. Or maybe lock the link and make it unaccessable after visiting it one time and only be able to unlock it through the admin panel with a toggle or something. These are the ideas I have but don't know how to code. How can I implement this in django. I am also open to solutions on the front end with JS. Is this a case for django permissions or is it something else?. an image of the the levels dashboard I have tried targeting links using :visited pseudo class but not what I wanted. -

Can create extended Field classes for Django Models introduce unexpected problems?
I'm starting a Django project and in my early design I'm thinking about extending the model's fields classes to add a new optional attribute belongs_to. It will be a list of elements that later would serve the purpose of filtering the object attributes. Example: # models.py class CustomCharField(models.CharField): def __init__(self, belongs_to: list=list(), *args: Any, **kwargs: Any) -> None: super().__init__(*args, **kwargs) self.belongs_to = belongs_to class ModeloTest(models.Model): attr1 = CustomCharField(max_length=20, belongs_to=list(('type1', 'type2'))) attr2 = CustomCharField(max_length=10) attr3 = CustomCharField(max_length=10, belongs_to=list(('type1',))) attr4 = CustomCharField(max_length=10, belongs_to=list(('type2', 'type3'))) attr5 = CustomCharField(max_length=10, belongs_to=list(('type4'))) attr6 = CustomCharField(max_length=10, belongs_to=list(('type3',))) def fields_belongs_to(self, search_element): # 'id' Field is not Custom, doesn't have or need 'belongs_to' and can be ignored fields = [field for field in self._meta.fields if field.name != 'id'] filtered_fields = [field for field in fields if search_element in field.belongs_to] output = dict() for field in filtered_fields: output[field.name] = getattr(self, field.name) return output # views.py def main_view(request): m = ModeloTest.objects.first() context = { 'type1': m.fields_belongs_to('type1'), } return render(request, 'placeholder/main.html', context) With this design I can organize and classify fields in the Model and with the object.fields_belongs_to(search_element) method I get a dict of the Fields that belong to the type selected in search_element.
