Django is always returning 404 while testing. "The requested resource was not found on this server."
I have an Django API that I build quickly, and now I want to add some tests to ensure is stable. The problem is that Django simply refuses to let me access any resource on the server. It can't find any URL. I have some models, but this test is with the User model. # auth/urls.py urlpatters = [ ... path( "user/<str:email>/", views.UserView.as_view(), name="public staff user", ), ... ] # auth/tests/tests.py (Folder workign as a submodule, tests.py is a temporary name) from django.test import TestCase from django.urls import reverse from rest_framework.test import APIClient, APITestCase from authentication.models import User import os # Create your tests here. class TestTestCase(APITestCase): def setUp(self): self.staff_user = User.objects.create( email="test@account.me", is_staff=True, is_active=True ) self.staff_user_password = "staff_password" self.staff_user.set_password(self.staff_user_password) def test_testing(self): print(User.objects.all()) url = reverse("public staff user", kwargs={"email": self.staff_user.email}) print(url) response = self.client.get( url, ) print(response.content) I have a few unused imports, but those don't matter. I create a User instance, and change it's password. Then, in the test, I try to retrieve it's data. I can confirm the user exists (the shell returns <QuerySet [<User: Employee#000>]>) and the url works (/api/user/test@account.me/ works with another email in the dev database). However, response.content returns the following: # Escaped for ease … -

Generating an encrypted file on a webpage daily
I have a python program that reads an encrypted file to extract the required settings and time. The encrypted file should be updated per each minute and should be accessed remotely by multiple users. Is there a way to generate that encrypted file on a webpage (with a fixed hyperlink; say www.website-name.com/log.txt) and replaces the older file at a specific time frame (for example, per minute, hourly, daily, etc). Then, I can access that file from its url. Is there a way to do that? -

How do I include an oninvalid attribute while using django widget tweaks?
{% render_field form.field_1 class="form-control mb-2" type="text" onkeyup="empty_select_check(this)" oninvalid="this.setCustomValidity(' ')" %} I am currently using django widget tweaks to render my fields. However, on some fields that are required, if users do not fill up those fields, the default "Please field in this field" or "Please select a list" will appear. I have tried using the invalid attribute which was recommended by stackoverflow on another question. This attribute works fine when I use it on an input element but when I insert it into widget tweaks, I get the following error: Template Syntax Error: Could not parse the remainder: '"this.setCustomValidity('' from '"this.setCustomValidity('' I am unsure of how I can remove the pop-up without using the oninvalid attribute. Anyone has any other plausible suggestions? As seen below, i have attempted to replace the "pop-up" with my js way of checking the field. JS doesnt work and pop-up still shows up though. function empty_value_check(ele) { let value = ele.value; if (value === '') { $(ele).addClass('is-invalid'); } else { $(ele).removeClass('is-invalid'); } } function empty_value_all() { $('#field_1_id').each(empty_value_check(this)); return !($('.is-invalid').length > 0) } -
Set ordering in django to use language specific order
I have a Django app with the following models that have the ordering set with class Meta: class Akutsomatik(models.Model): bereichname = models.CharField(max_length=200) class Meta: ordering = ['bereichname'] def __str__(self): return self.name # This model is only included in the example for better understanding class Klinik(models.Model): name = models.CharField(max_length=200) akutsomatik = models.ManyToManyField(Akutsomatik, blank=True) def __str__(self): return self.name And my template: {% if klinik.akutsomatik.all %} <ul> {% for akutsomatik in klinik.akutsomatik.all %} <li>{{ akutsomatik }}</li> {% endfor %} </ul> {% endif %} The problem is that the data of my app is in German and the ordering is set to UTF-8. The output would look something like that: Augenchirurgie / Ophtalmologie Brustchirurgie Viszeralchirurgie Wiederherstellende Chirurgie Ästhetische Chirurgie but in German it should be like: Ästhetische Chirurgie Augenchirurgie / Ophtalmologie Brustchirurgie Viszeralchirurgie Wiederherstellende Chirurgie Note that the Ästhetische Chirurgie should come before Augenchirurgie / Ophtalmologie. Does anyone now if there is a way to set the collation in class Meta? I tried the following as decribed [here][1]: class Meta: ordering = [Func('bereichname', function='utf8_general_ci', template='(%(expressions)s) COLLATE "%(function)s"') ] But I get the following error: collation "utf8_general_ci" for encoding "UTF8" does not exist LINE 1: ...ER BY ("klinik_finder_akutsomatik"."bereichname") COLLATE "u...

how to update one only one field
I'm working on a small project using Django / Rest Framework.

How can I traverse through two list concurrently in one for loop using in django templates to be implemented in a chatbot app
So I am trying a chatbot application where the user will take a user string response and after that, the chatbot will throw a reply. Meaning that it should be able to traverse in two string lists user_response and chat_response in one for loop. The problem that I am having is that I have no idea how to implement this in Django that suits the way I need to implement it. I should implement it this way: {% for chat in user_chat#<-not sure here %} <div class="chat self animated slideInUp fast"> <div class="user-photo"> <img src="{% static 'images/account_200px.png'%}"alt="Self"></div> <div class="chat-message">{{ user_chat }} </div> </div> <div class="chat friend animated slideInUp fast"> <div class="user-photo"> <img src="{% static 'images/icon-at.png'%}"alt="Dog"></div> <div class="chat-message"> {{ response #<-the response from system|safe}} </div> </div> {% endfor %} Meaning in that one instance of a loop I should be able to render two divs with different classes that obviously have different messages that came from two different string lists. Like for loop{ render(user_chat) render(system_response) } Which in turn should produce this kind of response Given that: user_chat = ["Hi", "I am okay", "good!"] system_response = ["How are you", "How Okay are you?", "Oh that's great to hear"] Will make Hi … -

How to NOT override context in Django DetailView with get_context_method?
