Format DateField model in Django
I used DateTime Field to format the date, but doesn't seem to work, what could be the isssue, below is my code : from django.conf.locale.de import formats as de_formats de_formats.DATE_FORMAT = 'd.m.Y' This is the model : contract_signed_on = models.DateField( _('Contract signed on'), null=True, blank=True) I want the date format to be like this : 04.3.2022 but it's not showing the exact format -
How can I automaticall add the currently logged in user to django models in react
This is the link to my previous question which will help you understand this question (How do I use localstorage.getItem or setItem to send a post request in my react application?). Thanks to you guys, I can successfully make a post request in the frontend (react). However, am unable to automatically include or save the user in the database record. The username field in the database table is blank. The username field is automatically included when creating a post request in the admin page but not in frontend react. The previous question includes all the relevant code. Below is the model class. I am using custom user model and hence the email is my username: class ClientInformation(models.Model): user = models.OneToOneField( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, blank=True, null=True) age = models.TextField(max_length=10) phone_number = models.TextField(max_length=20) country = models.TextField(max_length=30) city = models.TextField(max_length=30, blank=False) alergy = models.TextField(max_length=500, null=True, default=None) gender = models.TextField(max_length=20, null=False, blank=False) last_update = models.DateTimeField(default=now) -

Permission denied on file django app published on IIS
I Have a django app puplished in my company's IIS that is reading the mail from an specific mail inbox registered in the tenant. I succesfully registered my python app on the tenant and use the credentials generated to read the inbox folder. everything works when I run my app locally using the manager.py file. However, when I want to enter the app through the IIS and I click on the view responsible of reading the mail i get the error: [Errno 13] Permission denied: 'o365_token.txt'.

React - redirecting to full url and not relative url
Good afternoon, I built a django form for my thesis work that I intend to interviewees. To make it more appealing and increase the number of answers (I hope! :)) I built a page using a tutorial on react. It looks very nice. The problem is that building my form with react looks like a nightmare. So I would like to have a button on my react page that once clicked redirect to my django html page with the form. I looked online but none of the topics I found did the trick (React-Router External link, react-router redirect to a different domain url, react button onClick redirect page). I would like to have something like: <NavBtnLink to="http://127.0.0.1:8000/doctor/7f06cb1c-d68e-459e-9d07-ce4d52d2b50b/survey/%22%3ETake the survey</NavBtnLink> but that tries to redirect me to: http://localhost:3000/http://127.0.0.1:8000/doctor/7f06cb1c-d68e-459e-9d07-ce4d52d2b50b/survey/ instead of: http://127.0.0.1:8000/doctor/7f06cb1c-d68e-459e-9d07-ce4d52d2b50b/survey/ Any idea of things I could try (on top of what is suggested in the mentionned topics? -

Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable. - Django
I'm new to asking questions on SO, so bear with me. I know there are a lot of answers about this already, but none of them work. I've been working on making a Django web app, and now I have to deploy it so you can access it on mobile. I've been trying to get it running on Google Cloud Run, but no luck. I've made the Docker container, and that runs fine locally, but when I try to deploy the container, it gives me the following error: Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable. Logs for this revision might contain more information. The logs loop back to the exact same page, with no additional information. I've tried to switch the ports in the docker-compose.yml and Dockerfile to 80, 8000, 8080, and any variation in between, with no luck. I know with Django stuff you're meant to use the App Engine, but I've already loaded too much stuff into the sqlite3 database, and all the sources I can find for the App engine are about PostGres, which I don't have time to convert over to. … -

Django Initialise NOT value of Bool Field From Model in ModelAdmin Form

Pycord (Discord Bot) Inside Django View
So, I run a rather larger discord bot (couple thousand users atm, trying to grow it). On the same server, I have a Django instance that I use for model storage and web dev. I'm trying to implement an admin panel using some of the model information, but also some information from the discord API. Unfortunately, however, the way that Pycord/Discord.py bots are started, the function is continuous, so I can't just run things normally. So to get the Discord information in a view, I'm attempting this. async def baseAdmin(request): intents = discord.Intents.default() intents.members = True intents.messages = True intents.guilds = True intents.presences = True bot = discord.Bot(intents=intents) print('1') @bot.event async def on_ready(): print('3') n = bot.get_guild(815846750652465202) name = n.name await bot.close(); print("4") return render(request, 'website/success.html') print("2") bot.run("MYTOKEN"); However, nothing works. I've tried going back and forth between sync and async views, using bot.run with and without an await, and a couple more things. Alas, nothing works. With this specific set, I'm getting an asyncio.exceptions.CancelledError result, but errors have been all over the place. Any assistance is GREATLY appreciated. -

Django FORM_RENDERER for frontend only
By default Django uses this setting determine where the form widgets come from: FORM_RENDERER = 'django.forms.renderers.DjangoTemplates' As we want all labels removed, and apply some overrides, it was changed to: FORM_RENDERER = 'django.forms.renderers.TemplatesSetting' This all works fine for the frontend. However, it renders the backend unusable as now all labels are removed there as well. My question, how do I get Django to use the original setting for the admin? -
How to set LOGIN_URL variable in Django settings so it doesn't redirect anywhere while not logged in
When trying to access url get_room_messages if user is not logged in @login_required redirects him to: /accounts/login/?next=/get_room_messages (as specified in docs) I want it to do nothing (or redirect to the original url, in this example /get_room_messages). I don't want to hardcode it like @login_required(login_url='/get_room_messages'), ideal solution would be to get somehow original url and pass it into @login_required() decorator. @login_required() def get_room_messages(request): user_id = request.user.user_ID user = get_object_or_404(CustomUser, pk=user_id) Thank you for help! -

Save data and show it in one http request Django ORM
I'm working on a little app and I'm stuck with one "error" and maybe someone could help me. So basically what I'm trying to achieve is that I want to update two fields from a model (let's say that I have 5 fields in db) and I'm using SomeData.objects.filter(id=pk).update(data=test, data1=test1) but the idea is that I conclude that is necessary to send two requests from views.py ( first request will update the db and the second one will output data desired). The big question is, how can I achieve this in one single http call? The http method is GET but I'm sure that it doesn't matter. Thanks in advance! -

How can I instantiate multiple models on one user button press (Django)?
Design example image Code Snippet I'm trying to put together a CRM sort of website that allows users to create subjects and have tasks listed under them. These tasks all have a red or green circle under each week based on its completion status for that week. The problem is I'm not sure how to piece this all together. I can create a task object and have it be listed under the subject but cant find a way to create multiple completion objects and have each one link in with every task and week to allow the user to check off what they completed. I'd really appreciate if someone could point me in the direction as to how to split up the logic for these models so that I can piece them together. Thank you :D -
Django rest framework returning base64 image URL encoded
I have my viewset that returns a basse64 encoded image in the image variable: with open(f"image_file.jpg" , "rb") as image_file: order.image = base64.encodebytes(image_file.read()).decode('utf-8') The thing is, if this code is executed locally like python script.py it returns the right base64 and I can display it, but this viewset is returning a base64 that's URL encoded. Instead of returning something like NMR//9k=, it's returning NMR/9k%3D%0A. How can I change this? I need the proper base64 encoding to display the image on the front.
