Invalid redirect_uri in instagram oauth
I am using python django and django-allauth to implement oauth to instagram. I think I have set all the required things in instagram app setting and got the application id and secret. This is my app setting and I have added in my project to work with this configuration. This is my views.py from django.views.generic import TemplateView from allauth.socialaccount.models import SocialAccount class ConnectInstagram(TemplateView): template_name = 'connect.html' And connect.html file looks like this {% load socialaccount %} <a href="{% provider_login_url 'instagram' %}"> Connect with Instagram </a> I have already registered social applications in django admin site with site and application id and secret. This is my settings.py file import os from dotenv import load_dotenv from pathlib import Path load_dotenv() # Build paths inside the project like this: BASE_DIR / 'subdir'.

How to edit claims in ID Token supplied with openid scope in django Oauth toolkit?
When working with Django OAuth Toolkit, using OIDC if you supply openid as the scope in request you get a id_token with access token. This ID Token can initially be used to identify the user you have got access token for and also create a session. { "aud": "audience", "iat": 1681801110, "at_hash": "hash of included access token", "sub": "1", "given_name": "Dushyant", "preferred_username": "dsh", "iss": "authEndpointurl", "exp": 1681837110, "auth_time": 1681567804, "jti": "tokenid" } But I wish to modify the claims in this JWT ID Token, it reveals the primary key of the database of Authorization Server as the unique id of the user which i don't want in the claim called sub. I want to use another unique key as the value of sub claim. I tried overriding the response a Custom Backend: class CustomOAuthLibCore(OAuthLibCore): def __init__(self, server): super().__init__(server) def create_token_response(self, request): response_data = super().create_token_response(request) #Modify the response here return response_data And added this as the Custom Backend in the settings. "OAUTH2_BACKEND_CLASS":"pathto.CustomOAuthBackend", I haven't written any modification code for the response here since the token here is already created. I want to intercept this at earlier stage where the claims dict is being made. Where and how can I achieve this … -

Djnago path attribute is set to root "/"
I have no idea how to fix it. The URL path that the cookie is valid for can be specified. If the domain and path match, then the cookie will be sent in the request. If the path attribute is set too loosely, then it could leave the application vulnerable to attacks by other applications on the same server If the path attribute is set too loosely, then it could leave the application vulnerable to attacks by other applications on the same server which may help attacker to establish the authenticated session with other applications hosted under default directory Set the appropriate path in cookie interface I have tried doing this in settings.py CSRF_COOKIE_PATH = '/test/' but if 'mydomain/test' path exists then only it works for this path. otherwise for any other path, it do not show csrf_token and when I keep it default CSRF_COOKIE_PATH = '/' it gives as below screenshot cookies section I tried CSRF_COOKIE_PATH = '/test/' what I actually want is to change path from '/' to any other path if I hit any path -
Download the file from the server or output an error if there is one
I have something like this Python code: with open('test.bin', 'rb') as file: file_content = file.read() response = HttpResponse(file_content, content_type='application/octet-stream') response['Content-Disposition'] = f'attachment; filename=test.bin' return response There may not be a file, so you should return an error somewhere, but how to do it so that it can be read on Ajax and output to the user. $.ajax({ url: 'test', type: 'GET', headers: { 'X-CSRFToken': getCookie('csrftoken'), }, xhrFields: { 'responseType': 'blob' }, success: function(data, status, xhr) { var contentDisposition = xhr.getResponseHeader('Content-Disposition'); var matches = /filename=([^;]+)/ig.exec(contentDisposition); var fileName = (matches[1] || 'untitled').trim(); var blob = new Blob([data], {type: xhr.getResponseHeader('Content-Type')}); var link = document.createElement('a'); link.href = window.URL.createObjectURL(blob); link.download = fileName; link.click(); }, error: function(xhr, status, error) { }, }); But the fact is that because of the xhrFields field, the data is perceived as a blob, so in xhr.responseText(type string) I get [object Blob] How do I get the file downloaded and the error output in case of an error? -
How to use filter to check if strings stored in a Django array field are a substring of the input string
Here is how my model looks like. class TestModel(models.Model): test_field= ArrayField(models.CharField(max_length=255, null=True, blank=True),default=list) I want to filter objects which have any substring of the input string as an entry in their test_field. Example: Assume a TestModel object1 has the ['good','morning'] stored in its test_field. object2 has ['run','crew']. Input String is 'Good Evening'. The output should return a query set containing object1. -

Write an explicit .create() method for serializer schedule.serializers.WorkSuperSerializer, or set read_only=True on nested serializer fields. I went through a lot of solutions to the problem, for example, I declared the create() method: def create(self, validated_data): links_data = validated_data.pop('links') worksuper = WorkSuper.objects.create(**validated_data) for link_data in links_data: Link.objects.create(worksuper=worksuper, **link_data) return worksuper But it didn't fix the error((((( In general, here is my code: Models.py: class WorkSuper(models.Model): firstname = models.CharField("Имя", max_length=10, blank=True) lastname = models.CharField("Фамилия", max_length=30, blank=True) class Link(models.Model): links = models.ForeignKey(WorkSuper, related_name='links', on_delete=models.CASCADE, blank=True) linkname = models.CharField("linkname", max_length=100, blank=True) linkurl = models.CharField("linkurl", max_length=100, blank=True) … -
In the app engine dashbord, requests from uri are displayed that I don't know the origin, does anyone know where it comes from?
Dashboard do App engine A friend told me that it looks like wordpres was downloaded along with the app because they are common wordpress uris, but he's not sure. I thought that they were due to Google Cloud services (App engine, Storage, Logging, Build, Secret manager) but I'm not sure either? Is it one of those cases? Is it a problem and if so is there a fix? Obs: I don't know it it helps, but the site is develop with django, boostrap and jquery. I even write in browser the uri but nothing that i wouldn't expect appear. I don't even know how to work with wordpress. -
Annotation by condition
I have 2 models: class City(models.Model): title = models.CharField() class VisitedCity(models.Model): city = models.ForeignKey(City) user = models.ForeignKey(User) I want to make a queryset with annotated fields visited boolean type: if this city in visitedcity model and user=self.request.user => True if not => False `City.objects.annotate( ... something ... )` I tried to use annotate() like this one, but it is not work: queryset_visited = VisitedCity.objects.filter(user=self.request.user) queryset_all = City.objects.annotate( visited=Case( When(title__in=queryset_visited, then=Value(True)), default=Value(False) ) ) Could you please help me with this question? -
NPM error in Django application deployment in Render
I’m trying to deploy a Django application in Render. My operating system is Windows. I use tailwind and when it is executed in the Render virtual machine the command 'python manage.py tailwind build' appears the following error of npm: sh: 1: rimraf: not found npm ERR! code ELIFECYCLE npm ERR! syscall spawn npm ERR! file sh npm ERR! errno ENOENT npm ERR! theme@3.4.0 build:clean: `rimraf ../static/css/dist` npm ERR! spawn ENOENT npm ERR! npm ERR! Failed at the theme@3.4.0 build:clean script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above. I have in the requirements.txt nodejs==0.1.1 and npm==0.1.1. And in the settings.py: NPM_BIN_PATH = "/usr/bin/npm". Below I show the build.sh file: set -o errexit pip install -r requirements.txt python manage.py collectstatic --no-input python manage.py migrate python manage.py tailwind build if [[ $CREATE_SUPERUSER ]]; then python manage.py createsuperuser --no-input fi -
Custom "per-tenant" views in Django
I developed a multi-tenant Django app (single DB with single schema and domain-based, eg. https://tenant-xyz.esample.com) and I'd like to be able to customize some views according to the current tenant. For example, /my_app/some_view might include some logic while /my_app/tenant_xyz/some_view might behave in a different way. Of course I could also have /my_app/tenant_abcdef/some_unique_view_for_tenant_abcdef_only. Following Django's urls.py phylosophy, I guess custom views could be enclosed in their own views_tenant_xyz.py and tenant-related URLs would point to custom views files. The simplest intuition was to to dynamcally include tenants' custom views URLs in urls.py (without typing them statically). Given a urls.py fragment: urlpatterns = [ path('', include('my_app.urls')), path('admin/', admin.site.urls), ] I thougth I could include the following code in urls.py: for tenant in Tenant.objects.all(): urlpatterns += [ path(f'custom_views/{tenant.name}/', include(f'myapp.tenants.urls_{tenant.name}', namespace=f'customviews{tenant.name}')), ] and then define custom CVB (or functions) in each myapp.tenants.urls_{tenant.name}.py but I get an "SynchronousOnlyOperation at / You cannot call this from an async context - use a thread or sync_to_async." (I'm running ASGI with Gunicorn + Uvicorn workers). Btw I suppose using ORM inside settings.py is not the best approach. What would you advise me to do? Keep in mind that each tenant.name is a sort of slug. Thanks in advance.
