How to solve url parameter problem in Django?
I have a strange problem. I have a page that uses url parameters. Users can reach this site based on their project id and name and the group(csoport) name that stored in three models. This is a link for an example page: /performance/monthlyfeedback/{{ request.user.profile.csoport }} That link works fine if the name of the csoport is a number. If it is any kind of a text it gives me 404 error that I can't figure out why. models.py class Profile(models.Model): def __str__(self): return str(self.user) user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) csoport = models.CharField(max_length=100, null=True, blank=True) class Projekt_perf(models.Model): def __str__(self): return str(self.projekt_perf) projekt_perf = models.CharField(max_length=250) jogosult_01_perf = models.ForeignKey(User, on_delete=models.CASCADE) date = models.DateField(auto_now_add=True, auto_now=False, blank=True) class Performance_profile(models.Model): def __str__(self): return str(self.user_name) user_name = models.ForeignKey(User, on_delete=models.CASCADE) projekt_perf = models.ForeignKey(Projekt_perf,on_delete=models.CASCADE) views.py I am using raw query in the views. def obj_results(request, projekt_perf_id, projekt_perf, user_name_id, csoport): person = Projekt_perf.objects.raw('SELECT * FROM performance_projekt_perf INNER JOIN performance_performance_profile ON performance_projekt_perf.id = performance_performance_profile.projekt_perf_id INNER JOIN stressz_profile ON performance_performance_profile.user_name_id = stressz_profile.user_id WHERE performance_projekt_perf.id = %s AND projekt_perf = %s AND stressz_profile.user_name_id = %s AND stressz_profile.csoport = %s',[projekt_perf_id, projekt_perf, user_name_id, csoport]) context = { 'person': person, } return render(request, 'performance/obj-results.html', context) urls.py app_name = 'performance' urlpatterns = [ path('monthlyfeedback/<int:projekt_perf_id>', login_required(views.Performance_test), name='performance_feedback'), path('list/<int:projekt_perf_id>/<projekt_perf>', … -
Preparing data for a form view (django, drf, axios, vuejs)
I'm building a web application with Django, DRF, Axios and Vuejs. It works but I'm wondering what are best practices for handling such a case. Considering the form below : I want to create an Item for which I can assign a Company and a Contact. The Company is a model in its own as well as the Contact. The Contact field shows only contacts for the selected Company. How should I query the datas to be the most RESTful possible ? Query all the companies, query all the contacts, and make a computed property that shows only contacts of the currently selected company ? Query all the companies, and each time I select a company I query related Contacts only ? Other solution ? Both have pros and cons and I wonder what is the best way to handle this kind of situation. Also, if there are standard ways to design this. -

Auth0 login working only on localhost but won't redirect to my domain
I have no idea if I missed something, but I followed the Auth0 documentation and watched videos about is and set it up and everything works (localhost). Now I want to use it on my domain that I have. I added the settings for my domain over at auth0 website. But what happens is this I click on the login link on my website I go to the correct url http...../login/auth0 The request goes to the auth0 (my domain there) but with the redirect to localhost Removing the locahost from auth0 setting doesn't help since I'm still sending it as the return url. The issue here (I assume) are the arguments that I'm passing and I have no idea how to change them. I'm not sure if there is a way for creating a custom login view and then sending users over to auth0 or if there is some way to pass different value to the auth0 login view in order to change the returnTo url -

Circular Dependency Error when creating custom user for dj-stripe
I'm trying to create a subscription plan for my django app using stripe, essentially following the guide bellow to the letter: https://ordinarycoders.com/blog/article/django-stripe-monthly-subscription I'm using dj-stripe to sync my stripe products with my database. My problem is when I come to creating a custom user, I get a Circular Dependency Error when I attempt to migrate. from django.db import models from django.contrib.auth.models import AbstractUser from djstripe.models import Customer, Subscription class User(AbstractUser): customer = models.ForeignKey(Customer, null=True, blank=True, on_delete=models.SET_NULL, related_name='stripe_customer') subscription = models.ForeignKey(Subscription, null=True, blank=True, on_delete=models.SET_NULL, related_name='stripe_subscription') The full error: django.db.migrations.exceptions.CircularDependencyError: djstripe.0008_2_5, djstripe.0009_2_6, djstripe.0010_alter_customer_balance, custom_user.0001_initial, djstripe.0001_initial, djstripe.0007_2_4 I've tried deleting my database and all migrations, reinstalling the packages but nothing seems to work. Is there any way I can get around this? -
Django Infinite dynamic Multi-level nested category
I have three models for now suppose one is category another is subcategory and another is product. Before registering a product user should add subcategory and before adding subcategory we need to add category in subcategory table. So, now adding a products need to be like Men's Fashion (Category)-> Shirt(SubCategory)-> White shirt(Product). It is working fine and I have no issue with it. But there is sudden changes like If I need to add infinite subcategory suppose there maybe some products like to go through two subcategory Men's Fashion(Category) -> Footwear(SubCategory) -> Shoe(SubCategory) -> Premium shoe (Product) or maybe maybe some products like to go through two subcategory Men's Fashion(Category) -> Footwear(SubCategory) -> Shoe(SubCategory) -> Leather Shoe (Subcategory) -> Premium shoe (Product) It will depend on the user he can add as many as subcategory he wants. This has to be like dynamic but I am wondering how. If I take multiple data and add model dynamically (I don't know if I can do this with django because the how can I sync the db without using migrate command) this is pretty much confusing me and I am stuck here. Any kind of help would be really appreciated. class Category(models.Model): … -

How is the "required" attribute dynamically set on a MultiWidget?
There are 4x TextInput elements that comprise a MultiWidget. Only the first TextInput requires the required attribute. Yet required is being set on all four elements. Form.use_required_attribute is not suitable for my case due it's binary nature; either values for all form fields are required or not. I've set required=False to every possible place where it's potentially warranted, but I'm still not getting the desired result. How can I get just the first TextInput set to required? class MultiTagWidget(MultiWidget): def __init__(self, *args, **kwargs): widgets = [TextInput(attrs=kwargs['attrs']) for i in range(4)] super().__init__(widgets, *args, **kwargs) def decompress(self, value): if value: return value.split("_") return "" class TagField(MultiValueField): def __init__(self, *args, **kwargs): fields = [] for i in range(4): field = CharField(**{ "min_length": 1, "max_length": 25, "validators":[ RegexValidator("[<>`':;,.\"]", inverse_match=True) ] }) if i == 0: field.error_messages = { 'incomplete': "Provide at least 1 tag for your question" } field.required = True else: field.required = False fields.append(field) super().__init__(fields, *args, **kwargs) def compress(self, data_list): data_list = "_".join(list(set([tag.lower().strip() for tag in data_list]))) return data_list tags = TagField( widget=MultiTagWidget( attrs={"required": False} ), require_all_fields=False, help_text="Add up to 4 tags for your question" ) -
How to quickly see if all items in list of Primary Keys exist prior to bulk_create call?
I'm attempting to do a django bulk_create for a list of objects. However, every so often one of the objects in the bulk_create already exists (it's primary key has already been allocated) so an exception is raised and no objects get created. To fix this I added a loop over each of the new objects to test if they exist prior to the bulk_create call but this feels very inefficient. Is there way to accomplish the same result in fewer queries to the database? -

How inheritance works in object-oriented programming in Python
The Question from a noob :) Creating a text field in a model in Django, we do the following: class Book(models.Model): title = models.CharField(max_length=200) CharField, is a class with the following chain of inheritance File: django.db.models.fields.init Classes: class Field(RegisterLookupMixin) / class CharField(Field) And models.Model that is used to registrate a model, in turn, has the following chain of inheritance: File: django.db.models.base Classes: class ModelBase(type) / class Model(metaclass=ModelBase): Questions: How models works when registering a model.CharField ? CharField is not a direct descendant of models, then why can we specify them after each other? When registering a model, we declare class Book(models.Model). Specify CharField in the fields. Why can we do this, despite the fact that they are not directly related by inheritance? -
Creating a list in JavaScript from django variable is autoparsing strings as dates
I'm working in a django project and I'm sending a dataframe with "to_dict" to the template. The dataframe consist of dates and extra info that I deleted for ease of understanding. Im using that data in javascript, but I need the date as a string as the lib I'm using doesn't support date objects for some reason. The problem comes that when I make a list out of the parameter the dates get parsed automatically without me doing anything extra. So for this lines of code: listData = {{data|safe}}; console.log({{data|safe}}); console.log(listData); I get this result: So what i need is that creating a list doesn't parse the string to date and if possible the reason why is this happening. -
