Django redirect and modify GET parameters
I am implementing magic tokens and would like clean URLs. As a consequence, I would like to remove the token from the URL upon a successful user authentication. This is my attempt: def authenticate_via_token(get_response): def middleware(request): if request.session.get('authenticated', None): pass else: token = request.GET.get('token', None) if token: mt = MagicToken.fetch_by_token(token) if mt: request.session['authenticated'] = mt.email if not request.GET._mutable: request.GET._mutable = True request.GET['token'] = None request.GET._mutable = False else: print("invalid token") response = get_response(request) return response return middleware IE, I would like to send /products/product-detail/3?token=piyMlVMrmYblRwHcgwPEee --> /products/product-detail/3 It's possible that there may be additional GET parameters and I would like to keep them. Any input would be appreciated! -
Django/Js Direct to s3 App, Getting the Error: "The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256"

How to delete django model data on button click
I am creating a donation application. I have a screen in which people can click on if they want to learn more about a specific donation. On that screen, I have the following button: <button class="btn btn-success"onclick="showAlert()">Accept</button> . When this button is clicked, I bring up a confirmation alert, which is down bellow. (it uses swal to style but functions like a regular alert). When the alert comes up, if the user clicks the ok button, I want to delete the data that they are currently viewing and redirect them to another page. I am struggling with this, because I am not sure how to do this. Many people have said to use AJAX, but it does not seem to work. Javascript alert: swal({ title: "Accept Donation", text: "Are you sure you would like to accept the donation titled {{donation.title}}, which was posted on {{donation.date}} by {{donation.user}}?", icon: "info", buttons: true, }) .then((ok) => { if (ok) { swal("Donation successfully accepted, please contact {{donation.user}} at {{donation.phonenumber}}, for instructions as to when and where you should pick up the donation", { icon: "success", }); } }); } URL: (This is the unique url that renders the donation) path('donations/<int:pk>/', views.DonationDetail.as_view(), name='donation-detail'), I … -

Using django-filter generic view and paginate_by, how to build the pagination urls?

How to use inter-process communication in django with discord.py and discord-ext-ipc
I'm currently using discord-ext-ipc as an inter-process communication (IPC) extension for discord.py and linked this with quart-discord. Quart is an asyncio reimplementation of Flask and can natively serve WebSockets and other asynchronous stuff. I can so easily use a Web-Frontend as a Dashboard to interact with the discord users on a guild. Doing fun stuff like, using the discord role model for a permission model at the dashboard. Recently I stumbled over django and got hooked up with that powerful framework. As a learning project, I wanted to port the current working project into django but I stumbled over some impasses. First the working example with discord-ext-ipc and quart-discord: bot.py import logging import discord from discord.ext import commands, ipc intents = discord.Intents.default() logging.basicConfig(level=logging.DEBUG) TOKEN = DISCORD_TOKEN class MyBot(commands.Bot): def __init__(self,*args,**kwargs): super().__init__(*args,**kwargs) self.ipc = ipc.Server(self,secret_key = IPC_SECRET_KEY) async def on_ready(self): """Called upon the READY event""" print("Bot is ready.") async def on_ipc_ready(self): """Called upon the IPC Server being ready""" print("Ipc server is ready.") async def on_ipc_error(self, endpoint, error): """Called upon an error being raised within an IPC route""" print(endpoint, "raised", error) my_bot = MyBot(command_prefix = ">", intents = intents, chunk_guilds_at_startup = False) @my_bot.ipc.route() async def get_guild_ids(data): final = [] for guild in … -
How to add Query String Auth on all files in Django with Amazon S3
I am using Django with Amazon s3 with Libraries(django-storages boto3) To be specific the base.css is being served and fonts.css is not being served(Err 403). This is happening in Django Admin Console. I have confirmed that the fonts.css is in the bucket The problem being these files don't have query string auth # This is working GET https://bucket-name.s3.amazonaws.com/static/admin/css/base.css?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AFD34GE4VTLUKQOTHAW7%2F20210726%2Fus-east-2%2Fs3%2Faws4_request&X-Amz-Date=20210726T193438Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=815bd068805f60f90c6acf27b24028424e85afbf7ba2939b51471cab2ba8e8b9 # This isn't working GET https://bucket-name.s3.amazonaws.com/static/admin/css/fonts.css Almost all static files are being served The fonts.css is not in the HTML page source and maybe is being called from a JS code that is not appending the Query String Auth Also when I shift from S3 to django default storage, it works perfectly fine. -
Django Slugs as principal url
I want to do the following, so that the profile of each registered user can be seen as follows: http://127.0.0.1:8000/username/ I was able to achieve this, the problem is when wanting to create another page, for example http://127.0.0.1:8000/explore/ Django consider "explore" as a user and throw me a 404 error. this is my urls.py urlpatterns = [ path("<slug:slug>/", PerfilView.as_view(), name="perfil"), path("explore/", UserListView.as_view(), name="explore"), ] Am I doing it the right way or am I unable to do this with django?

Replace Default PK slug with Multiple Lookup Fields for ModelViewSet
I have two slugs, against which I run queries. Thanks to base class MultipleFieldLookupMixin, which my view class is inherited from and thus allows me to have multiple lookup_fields. We know that when ModelViewSet is used with DefaultRouter, appends a pk at the end of URL, which I don't want. For example, when I do this: router = DefaultRouter() router.register(r'organization', OrganizationModelViewSet, basename='organization') urlpatterns = [ path('viewset/', include(router.urls)), path('viewset/<str:device>/<str:start_time>/', include(router.urls)) ] it gives me the URL mydomain.com/viewset/<str:device>/<str:start_time>/organization/<int:pk>/ I don't want this pk at the end. If we can remove organization, that's even better. I want the endpoint to be, mydomain.com/<str:device>/<str:start_time>/. More playing around, I learned that adding extra_kwargs like this in my serializer class, extra_kwargs = { 'url': {'lookup_field': 'start_time'} } and modify lookup_fields in view class, with singular lookup field, like lookup_field, with value let's say, start_time. To clarify, changing lookup_fields = ["device", "start_time"] with lookup_field = "start_time" and also modify the URL accordingly by removing the start_time slug, then URL becomes mydomain.com/viewset/<str:device>/organization/<str:start_time>/ modify singular lookup_field with org, apparently gives us more or less the desired URL, but doesn't get the job done because we have a single lookup_field now! mydomain.com/viewset/str:device/organization/str:start_time/ If we edit this line router.register(r'organization', DeviceActivityModelViewSet, basename='device_activity') to … -
How to implement only accepting username and token as request in django view and not password?
I have created a custom User model in Django that has username, email, password and some other fields. I am using jwt token which can be acquired from /token after providing valid username and password of a user. I have created a serializer for /authstatus and implemented it's view in views.py. Currently it works only when both username and password are provided with authentication token as header. Is there any way to ask only username and not password from user as a request for /authstatus? Code: Serializer: class AuthSerializer(serializers.ModelSerializer): password = serializers.CharField( required=True, style={"input_type": "password"}, write_only=True ) class Meta: model = get_user_model() fields = ["id", "username", "password", "auth_status"] read_only_fields = ["id"] Any help will be appreciated.

Add general [to all models] queryset method
I can create a new class from models.QuerySet to override a specific model queryset manager, but is it possible to write a method that applies to all models? For example: Every time i need to see the unique values of a variable, i need to write (*using SQLite) list(map(lambda v: v[my_var], qs.values(my_var).distinct().order_by())) But it would be nice to have something like my_queryset.unique_values(my_var) # Returns [value1, value2, value3, ...] Without having to specify it to every model -

Azure AD with Django Rest Framework and React [dj-rest-auth allauth]
I'm trying to integrate Azure AD to an existing Django Rest Framework project. I found dj-rest-auth as a great solution for this purpose. It uses django-allauth. I managed to configure it on my Django project, but I have no idea which is the next step. So for now I have configured: urlpatterns = [ ... path(r'auth/azure', AzureLogin.as_view(), name='azure_login') ] which created a new endpoint with 3 optional parameters: access_token, code and id_token. I have also register an app on Azure Active Directory, but I have no idea how to proceed. Note: I am using React for front-end. -
Django Calendar Recommendation - HTMLCalendar no Weekly View
