Django: I'm almost positive my code is right but it's not working
Using the URLconf defined in lecture3.urls, Django tried these URL patterns, in this order: admin/ hello/ newyear/ tasks/ [name='index'] tasks/ add [name='add'] The current path, tasks/add/, didn't match any of these. I'm become frustrated because I'm very confident that my code is right. Here is my urls.py code from tasks directory: from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index"), path("add", views.add, name="add") ] Here is my urls.py code from project directory: urlpatterns = [ path('admin/', admin.site.urls), path('hello/', include("hello.urls")), path('newyear/', include("newyear.urls")), path('tasks/', include("tasks.urls")) ] I don't think anything is wrong with the project directory because tasks works but tasks/add does not. -
Django getting related objects from M2M
For example, I have three Models in django: class Car(models.Models): range = models.DecimalField() speed = models.DecimalField() def __str__(self): return self.speed class Group_of_Cars(models.Models): name = models.CharField() starting_city = models. CharField() car = models.ManyToManyField(Car) def __str__(self): return self.name class Arrival_time(models.Models): Location_of_ArrivalPoint = models.CharField() Last_known_location_of_CarGroup = models.CharField() Group_of_Cars = models.ForeignKey(Group_of_Cars) def function(self): "Get speed of the "Car" in "Group_of_Cars" def __str__(self): return self. Location_of_ArrivalPoint This is an example of what I want to do, not my actual models. The idea is for the user to input a series of values for the type of "Cars" such as speed and range. I'd like "Cars" to be selected when defining parameters for "a Group_of_Cars". What I'm not sure how to do is how to get the speed of the car, for the Group_of_Cars for which I need to calculate an arrival time (Group_of_Cars consists of one type of car and I'd like 'Arrival_time' to be its own table). Thank you for any input. -
'Next' page - Django
I'm building an ecommerce and there is the following scenario: user is on the cart page and clicks on the checkout page. Two things may happen: If he is not logged in, he is redirected to the login page and if he has an account, then he goes to checkout page: Cart page -> Checkout page -> Login page -> Checkout page It's working perfectly. If the user has not previosly registered, the user clicks on a link to the register page and then he goes to checkout page: Cart page -> Checkout page -> Login page -> Register page -> Checkout page It's not working. Inside the login page there is a link to go to the register page and I tried to attach the 'next' parameter but after the user has registered, he is not going to the checkout page: <a href="{% url 'account:register' %}?next={{ next }}">Do not have an account? Register now!</a> Any help? Do I need to code something inside the views.register? I thought only the link could help me! Thank you! -

Django - Handle a user vote per set amount of time
I'm working on a Django site that allows users to post to car shows and then vote for entries. Previously you could just vote for your top 3, but now I'm trying to add the ability to re-vote after some configurable amount of time (eg. daily, weekly). The first option lent itself to Django m2m fields nicely. Essentially just added a 'votes' m2m field to each entry and then tracked who voted. With timing involved though I separated it out into a new 'vote' model as shown below. The problem I'm having though is it introduces some pretty complicated queries where anytime I want to get whether a user can vote, I have to check against the timestamps. I was wondering if anyone had a better way to handle this or a clever way of integrating into the model an 'active' indicator in terms of whether the vote has expired based on the timing of the event. class Vote(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, null=True, related_name="votes", on_delete=models.CASCADE, ) post = models.ForeignKey( Post, related_name='votes', on_delete=models.CASCADE, ) timestamp = models.DateTimeField(auto_now_add=True) An example query: # Returns an active vote of a user/entrant combo that has not been reset by a voting period. def get_active_vote(self, … -
Django: 'int' object is not iterable when different serializers in a Viewset
I have an issue when making a GET request on this endpoint: /api/stock/{bar_id}/. It should return stock information for a specific Bar ID. In my schema, the Stock model contains the following properties: bar_id as a foreign key. ref_id as a foreign key. stock as integer. sold as integer. In order to get the relevant information, I intended on calling the BarDetailsSerializer through the Stock Viewset, thinking it might be easier than having to filter the Stock table according to the bar_id value provided in the URL, as it would automatically provide the Stock collection related to that specific Bar ID. Making a GET request on http://localhost:8000/api/bars/1 (as shown below) provides the information I need. However when I'm trying to get this response via the Stock Viewset with this end-point http://localhost:8000/api/stocks/1 I get the following error: TypeError at /api/stocks/1/ 'int' object is not iterable So is what I'm trying to do even possible in the first place, or is there a better way or some best practise to apply here? Thanks for your responses! Here is my Stock Serializer file: from rest_framework import serializers from ..models.model_stock import Stock from .serializers_reference import * from .serializers_bar import * class StockIndexSerializer(serializers.ModelSerializer): """ Serializer … -

Django getting one to many on same query
I need to display a view with Courses with its dependable Lectures on an accordion in html. A Course has many Lectures. class Course(models.Model): title = models.CharField(max_length=1500) def __str__(self): return self.title class Lecture(models.Model): title = models.CharField(max_length=1500) course = models.ForeignKey(Course, on_delete=models.CASCADE) content = models.TextField() def __str__(self): return self.title It seems like all the examples I have found. Get the relationship after doing a filter or getting the first object like this: Course.objects.first().lecture_set.all() This gets all the lectures for the first one. But I need to get all Courses with all lectures. Something like this: Course.objects.all().lecture_set.all() or Course.objects.filter('all').lecture_set.all() This way I could iterate over Courses and then on each Course iterate again with Course.lectures Does anyone know the best practice to achieve this? -
Upload File using Vue axios and Django Python Backend
I have VueJs as my front end where i have upload component and using formdata to create request and axios to make rest api call to backend written in Django Python. My Front upload method looks like: uploadFiles() { if (!this.currentFile) { this.message = "Please select a file!"; return } else { let formData = new FormData(); formData.append("file", this.currentFile); const instance = axios.create({ baseURL: "<URL>", withCredentials: false, }); instance .post("/test/", formData, { headers: { "content-type": "multipart/form-data", }, }) .then((response) => { console.log("Success!") console.log({ response }) }) .catch((error) => { console.log({ error }) }) } }, Now backed micro service is Django Python where I want to use the file. However i am not getting the file here. Code looks like below @api_view(['POST']) def attachment(request): myFile = request.FILES myfile2 = request.data.initial_data i tried above two ways to extract files from request object but no success, however it works if i send request via postman.
