Change URL Path for View Profile Page - Django
How would one go about creating a user-profile page that other users can view without being able to edit the profile unless they are the user? The thing I'm trying to work out is how the url routing would work, is it best practice to store a user's profile on a profile/ or <user_id> page and then load in the individual user's data like recent posts using the username or id passed through the url? Also would this be handled by the one view and template and just use {% if request.user == profile.user %} to display things like edit profile etc? my problem is any user can edit for others there profiles when he edit url for example my id is www.test.com/profile/44/ and other user have this id www.test.com/profile/40/ okay ,, now when i edit the link to be 40 not 44 i can access and edit the second user ! how to fix that models.py : class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email_confirmed = models.BooleanField(default=False) @receiver(post_save, sender=User) def update_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) instance.profile.save() def __str__(self): return self.user urls.py : from django.urls import path from blog_app.views import ProfileView urlpatterns = [ path('profile/<int:pk>/', ProfileView.as_view(), name='profile'), ] forms.py … -

Using Django admin application AND disabling session middleware?
I am building a django server for an API that relies on JWT (or Token based - https://www.django-rest-framework.org/api-guide/authentication/#tokenauthentication) authentication for our users. I don't need session based authentication for any purpose. It creates an unnecessary query on each request, and also authenticates users when I don't want to authenticate them (I want browsers to only authenticate when it includes an Authentication header in the request, and stay AnnonymousUser otherwise. This is because it creates issues in some of my middlewares where I verify if I am dealing with a guest or a authenticated user). However, the issue comes when I try to use the admin application as well (I can't imagine building this app without the use of the django admin page). When I remove the session-related middlewares:(django.contrib.sessions.middleware.SessionMiddleware, django.contrib.auth.middleware.AuthenticationMiddleware and django.contrib.messages.middleware.MessageMiddleware) from my settings file, I get the following error when I do a runserver: ERRORS: ?: (admin.E408) 'django.contrib.auth.middleware.AuthenticationMiddleware' must be in MIDDLEWARE in order to use the admin application. ?: (admin.E409) 'django.contrib.messages.middleware.MessageMiddleware' must be in MIDDLEWARE in order to use the admin application. ?: (admin.E410) 'django.contrib.sessions.middleware.SessionMiddleware' must be in MIDDLEWARE in order to use the admin application. Can someone think of a workaround where I can disable sessions in … -
React/Django: Database works, but React Is not Rendering the Views
I am trying to send information from my API and render it via React, but I get a blank screen. I am newer to fullstack development, so I am not sure where the disconnect. I can view dataentries I've created in the api, but cannot render these. I tried rendering the data is my models.py with my App.js App.js import React, { Component } from "react"; import { render } from "react-dom"; class App extends Component { constructor(props) { super(props); this.state = { data: [], loaded: false, placeholder: "Loading" }; } componentDidMount() { fetch("events/api") .then(response => { return response.json(); }) .then(data => { this.setState(() => { return { data, loaded: true }; }); }); } render() { return ( <div> {this.state.data.map(events => { return ( <div> Event: {events.title} Details {events.details} </div> ); })} </div> ); } } export default App; const container = document.getElementById("api"); render(<App />, container); models.py from django.db import models # Create your models here. class Events(models.Model): title = models.CharField(max_length=100) details = models.CharField(max_length=100) Please let me know if you need anything else. -

showing error in map while fetching data in Reactjs after authentication in CRUD django REST api?
i am trying to do a CRUD app with backend in Django Rest Api and in frontend it would be react-hooks. The main functionality will be, after authentication it would show tasks created by the user and only user would see and edit, delete etc his own tasks. i have uploaded the API in heroku and Here is Api link and here is the openapi look. and you can find the source code in the github and here is the codesandbox for frontend FYI: i couldn't link the backend with the codesandbox frontend but in localhost frontend can communicate with the backend django part. i have used corsheaders to separate frontend and backend. i am practicing in this way just because the backend API would be reusable. i am not sure whether it is a professional practice or not. though i couldn't link my api with the codesandbox and it is for the show of my whole code. in dashboard.js, the below part is working: useEffect(() => { if (localStorage.getItem("token") === null) { window.location.replace("http://localhost:3000/login"); } else { fetch("http://127.0.0.1:8000/api/auth/user/", { method: "GET", headers: { "Content-Type": "application/json", Authorization: `Token ${localStorage.getItem('token')}`, }, }).then(res=>res.json()) .then(data=>{ setUserEmail(data.email); setLoading(false) setUsername(data.username) }) } }, []); Here the … -

Changing the size of bootstrap cards in a Django project?
I'm working on a simple Django project with bootstrap. I have a set of cards being displayed on a page, and the cards are showing just fine (Don't mind the place holder images). I've been reading the bootstrap docs about cards, but since I have less knowledge of CSS than I'd like, I can't figure out how to simply change the size of the cards so they are larger and stacked in rows instead of one column. This is my HTML template for this page. It just uses a for-loop to go through my projects and make a card for each. You can see I have the title and text worked out, and the URL to 'See Details'. {% extends "base.html" %} {% load static %} {% block page_content %} <h1>Projects</h1> <div class="row"> {% for project in projects %} <div class="col-md-4"> <div class="card mb-2"> <img class="card-img-top" src="{% static project.image %}"> <div class="card-body"> <h5 class="card-title">{{ project.title }}</h5> <p class="card-text">{{ project.description }}</p> <a href="{% url 'project_detail' project.pk %}" class="btn btn-primary"> See Details </a> </div> </div> </div> {% endfor %} </div> {% endblock %} The Base.html is just linking to the bootstrap and all the html for the top of the page.

Creating Evaluated Field in Django By Applying Aggregation 2 Fields
I am in phase of learning Django framework and I need some help to understand how to generate an evaluated field by summing up two inputs by user. I've used the code below where ops1 and ops2 will be provided by user and I need to show their sum in field total_ops at runtime. I've used the code below but that doesn't seems to work. class ManHour(models.Model): date = models.DateTimeField(auto_now=True) class Operations(models.Model): ops1 = models.DecimalField(max_digits= 5, decimal_places= 3) ops2 = models.DecimalField(max_digits= 5, decimal_places= 3) total_ops = Operations.ops1 + Operations.ops2 Error from code above TypeError: unsupported operand type(s) for +: 'DeferredAttribute' and 'DeferredAttribute'
