How i can change password on Django
i wanna change django password without using the default view , i passed the PasswordChangeForm to the view but i didnt know how to post it class UpdateUserView(UpdateView): model = User template_name = 'test.html' form_class = UserUpdateForm success_url = '/' def get_context_data(self, *args, **kwargs): data = super().get_context_data(**kwargs) data['PasswordChangeForm'] = PasswordChangeForm(self.request.user) return data def post(self, request, *args, **kwargs): change_pw = User(password=request.POST.get('id_new_password1')) change_pw.save() def get_object(self): return self.request.user -
Django Model method test
I have model like this: class Users(models.Model): pin = models.CharField(max_length=16, unique=True) name = models.CharField(max_length=64) surname = models.CharField(max_length=64, blank=True, null=True) patronymic = models.CharField(max_length=64, blank=True, null=True) def get_full_name(self): name = self.name surname = self.surname if self.surname is None: surname = '' if self.name is None: name = '' return str(name) + ' ' + str(surname) I want to write a test case for get_full_name method. Currently I wrote something like this: class TestUsersModel(TestCase): def setUp(self): self.data1 = Users.objects.create(name='Bob', pin='1') self.data2 = Users.objects.create(surname='Alex', pin='2') def test_users_model_entry(self): data = self.data1 self.assertTrue(isinstance(data, Users)) def test_users_full_name_only_name(self): data = self.data1.get_full_name() self.assertEquals(data,'Bob ') def test_users_full_name_only_surname(self): data = self.data2.get_full_name() self.assertEquals(data,' Alex') but when I check with coverage it says me that I have to write test case for this: What I am missing here? -
Have to display data, from django using form and optional value

Access to users update and delete views in allauth is accessible to other users
Just followed through all the allauth documentation setting up a site with user registration. Subclassed it to extend the fields. All working fine except that I can signup with a new account and delete/update any other account just by changing the url to supply their user id instead the logged in user. I must be missing a setting that I can't find documented anywhere - I'm really surprised this is the default behaviour. I've added a slug field to the user model with a random alphanumeric and changed the views to use this - mostly because I hate using pk's in urls, particularly in a situation that potentially exposes user accounts like this. This mitigates the risk at least but it's still open. Any allauth developers out there know what solution to this would be? -
Django After LDAP Authentication leads to {"detail":"Authentication credentials were not provided."}
I know that issue around '"detail": "Authentication credentials were not provided.' was in a similar way already posted several times. However, the answers I found o far did help me. I have a Django app that I would like to deploy. In this App I have several Rest-APIs defined such as class MyViewSet(ReadOnlyModelViewSet): ... permission_classes = (permissions.IsAuthenticated,) AS Authentification Backend I use "django_python3_ldap.auth.LDAPBackend" with the following setting in the setting.py file AUTHENTICATION_BACKENDS = ( 'django_python3_ldap.auth.LDAPBackend', ) LDAP_AUTH_URL = "ldaps://XXX.XXX.XXX.XXX:XXX" LDAP_AUTH_FORMAT_USERNAME = "django_python3_ldap.utils.format_username_active_directory_principal" # The LDAP search base for looking up users. LDAP_AUTH_SEARCH_BASE = "ou=XXX,dc=XXX,dc=XXX" # LDAP Credtials LDAP_AUTH_CONNECTION_USERNAME = XXX LDAP_AUTH_CONNECTION_PASSWORD = XXX # Adapt filter def custom_format_search_filters(ldap_fields): search_filters = [("(&(objectClass=user)(sAMAccountName=" + '{user}' + "))").format(user=user_id)] return search_filters LDAP_AUTH_FORMAT_SEARCH_FILTERS = custom_format_search_filters On my locale windows machine, everything works well. After successful authentication, I can trigger the events that raise the rest-get call. I then deployed the project on an EC2 Amazon Linux 2 AMI machine. Here I added to the nginx setting the following code: server { # URL that is communicating with the client listen XXX.XXX.XXX.XXX:9000; server_name XXX.XXX.XXX.XXX; # Locatio for the logs access_log /data/webapp_project/logs/nginx-access.log; error_log /data/webapp_project/logs/nginx-error.log; # Gunicorn IP+Proxy location / { proxy_pass http://127.0.0.1:8001; proxy_set_header Host $http_host; } location … -

No 'Access-Control-Allow-Origin' header is present on the requested resource Occurs only when send video as request data Django + React
I am using django for backend/rest api and React for frontend. Both are on different servers.

Wrong links inside django app behind nginx reverse proxy

Imagine some intranet virtual machine with some nginx configuration where all requests to https://something.smth/django/ will be forwarded to docker container where i have another nginx and django app. Home page is fine and django app normaly loads but when i click on some link django will set url to https://something.smth/some-link/ instead of https://something.smth/django/some-link/.

How to access request.user with AbstractUser class
I am trying to create an order object and assign the order's customer field (which is a foreign key for User) to the current user. Even though it passes the if statement and it can authenticate the request.user, it assigns customer as a blank value. When I print customer it prints a blank line, however when I print customer.id, it prints the ID of the customer. This happens in all views in the project so its a global issue I belive this has something to do with the fact that my user class is inheriting from AbstractUser utils.py def cartData(request): if request.user.is_authenticated: print('This will print') customer = request.user print(customer) print(customer.id) order, created = Order.objects.get_or_create(customer=customer, complete=False) models.py from django.db import models from django.contrib.auth.models import AbstractUser class User(AbstractUser): author = models.BooleanField(default=False) settings.py AUTH_USER_MODEL = 'main.User' I feel like this may be an easy one but I can't figure it out! Thanks. -
How to implement as new Django application whose data are based on MS Access?
I need to implement a new version from scratch of an old software (the new version will be web based). The data is already available in a MS Access database. The company wants to use the new application while the old one is still on production. The technology I chose to develop the new version is Django. The issue is the database technology. I want to use postresql. Is there a way to easily implement the new version while being based on MS Access + postgresql in parallel? I cannot modify the old software to adapt its backend to postgres and Django does not seem to provide support for MS Access on Linux. Is there an alternative way here? -
Will .save() data from Api directly to db be faster than sending it from a Django form?
I am pulling a lot of data from an API to my django template and I keep getting a 504 timeout error so it never finishes. I can cut the data I am calling in half and it prints just fine. Will I get any error if I pull the data from the api and save it to my db straight from my view?? -
How to return an HTML file in Django that is NOT a template?
I have a particular HTML file that I want to show in Django. This file is generated externally and will not use Django template syntax. In fact, it includes some syntax that confuses the Django template generator (like {{ #something }}) and makes it return an error. What is the best way to return this particular HTML page in a way that does not trigger the template syntax to be used? I use this now, and it works, but is this the recommended way? Any drawbacks? def annual_report(request): from django.http import HttpResponse html_content = open("templates/reports/annualreport.html") return HttpResponse(html_content) -

Mocking external API in Django
I am trying to mock external api in Django but not sure how to do it properly. Basically, it must mock the json data from external API and then create a new object if all values are valid. The program fetches the geolocation data based on given IP address and saves the object in database if response data includes all required fields. So, how I can mock this process to test a new object creation? services.py import os import requests from .exceptions import ExternalApiException def get_location(ip): url = f'http://api.ipstack.com/{ip}' params = {'access_key': os.environ.get('ACCESS_KEY')} try: res = requests.get(url, params=params) data = res.json() return { 'ip':data['ip'], 'country_name':data['country_name'], 'region_code':data['region_code'], 'city':data['city'], 'latitude':data['latitude'], 'longitude':data['longitude'], 'zip_code':data['zip'] } except requests.exceptions.ConnectionError: raise ExternalApiException('Connection error occured during the fetch process') except requests.exceptions.Timeout: raise ExternalApiException("Connection timeout. Please check your internet connection and try again later") except requests.exceptions.TooManyRedirects: raise ExternalApiException("Too many redirects") except requests.exceptions.RequestException: raise SystemExit(e) tests.py #I am lost in this part @patch('geolocation.services.get_location') def test_create_basic_geolocation(self, mock_request): """Test creating geolocation data""" payload = { 'ip': '', } res = self.client.post(LOCATIONS_URL, payload) self.assertTrue(res.data['ip']) Thanks for any help. -

Use non model django fields in django filter

django's sql for terminal functions
I know that in order to see the generated SQL statement for queries I could use the .query function (e.g. str(Model.objects.all().query), or same with filter, etc.) I want to see the generated SQL statements for terminal functions used on query sets (e.g. Model.objects.count(), Model.objects.update(...), etc.). As the function is called it's executed without giving out an object like QuerySet to have the query on. So is there a way to see the generated SQL statement for these kind of operations without executing them and looking back at logs, etc.? -
