How to add a subdomain to a django URL?
I just have a simple question: How can I add a subdomain to my django url, like: forums.websitename.com or account.websitename.com? Since my URLS were starting to get messy, I would like to add subdomains to my website that is still in development. Thank you for all possible help. -
Error when trying to use 'platform login' command in Platform.sh
I'm trying to use platform.sh in my python virtual environment, but when I try to run 'platform login' in a command prompt to login, it will not work. The login browser page does open and says I logged in successfully, but the command prompt says '[RequestException] cURL error 60: SSL certificate problem: unable to get local issuer certificate'. Here is the full output of the command prompt (ll_env) C:\Users\david\PycharmProjects\pythonProject2\learning_log>platform login Opened URL: http://127.0.0.1:5000 Please use the browser to log in. Help: Leave this command running during login. If you need to quit, use Ctrl+C. Login information received. Verifying... [RequestException] cURL error 60: SSL certificate problem: unable to get local issuer certificate I tried quite a few things. I downloaded cacert.pem and set it up, and I also asked ChatGPT, who had no clue on what was going on. It kept presenting 'solutions' that would do nothing to help. -
Why does request.COOKIES periodically return an empty dict?
I set a cookie in my view like so: response.set_cookie( 'cookie_name', 'true', max_age=100000 ) The cookie sets ok, and is viewable in dev tools. I have a tag which checks for a specific cookie on every page load: @register.simple_tag(takes_context=True) def get_cookie_status(context): request = context['request'] print(request.COOKIES) Around 40% of the time, this prints an empty dictionary and I have absolutely no idea why. As I said above, Django picks up no cookies at all, but the loaded page has all of the expected cookies present. Is there any common reason why this would occur? -

Django: Vendor Profile Not Detected Despite Being Created
I am working on a Django project where each user can have an associated vendor profile. I've created a vendor profile for a user, but when I try to access the vendor's shop, it always renders the no_vendor.html page, indicating that the vendor profile does not exist.

Iterate through all the days in a month in DJANGO template
enter image description here I have a model table like above which contains two columns on which dates on which an item is being sold in a month. I want to show the entire month table in Django template instead of showing only the dates of sale, and on each day showing "yes" if the sale is there and keeping blank if no sale is there on that day.

Where to write queries in rest api, and how to secure it
I will make an application with Flutter. With Django, I will make a rest api to send data from mysql. I have never made an api before. In the tutorials I found, when I go to the api url, the whole database appears directly. My goal is to display the data in that url only in requests made via flutter. How do I make it hidden? In my second question, should I make the queries on flutter, or should I create a new url for each filtered query I will make in django. For example, if I have 200 queries, should I have 200 different url structures. I have not written any code yet, I am researching. -
Hello everyone! Does anyone know how I can georeference a png image with Gdal using Django?
I am trying to georeference a .png image with some control points, which would be the corner coordinates. I have achieved this using Gdal only with: from osgeo import gdal ds = gdal.Open(f'{filename}.png') gdal.Translate(filename + '.tif', ds, outputBounds=bounds) but when I try to put this in my DJANGO API I can't because Django GDAL doesn't have the gdal.translate method. Does anyone know what the equivalent of this function is in Django gdal or how can I georeference a png image with boundaries using django? -

Only first placeholder displayed in Django's UserCreationForm
I'm trying to make a sign-up page with a customized user creation form - add placeholders to the fields. I'm trying to do it this way: forms.py class SignUpForm(UserCreationForm): email = EmailField(max_length=200) class Meta: model = User fields = UserCreationForm.Meta.fields + ("password1", "password2", "email") widgets = { 'username': TextInput(attrs={'placeholder': 'Username'}), 'email': EmailInput(attrs={'placeholder': 'Email'}), 'password1': PasswordInput(attrs={'placeholder': 'Password'}), 'password2': PasswordInput(attrs={'placeholder': 'Repeat password'}), } However, it only affects the username's placeholders - the other ones are unaffected. What I've tried doing was to add the placeholder to the declaration of the email variable, which works. However, there has to be a simpler way to do it, and - even if I'd do that the passwords would still not have placeholders. I have also tried to make the fields variables, like email = CharField(TextInput(attrs{'placeholder': 'Email'}), but that didn't help too. Tried doing it as in the "Adding placeholder to UserCreationForm in Django" thread, but that didn't change anything. Other threads too, that's probably due to Django's version. Each time before trying it out I delete the site's browsing data to make sure it's not a client-side problem. -
When deploying Django to prod, Gunicorn lives in the virtual environment, but we deactivate the virtual environment when we go live with Nginx
I've been following a few tutorials online on how to setup Django, Postgres, Gunicorn and Nginx in production. I noticed that it is always recommended to install all Python dependencies inside the virtual environment. This includes Gunicorn. For example, we fire up our virtual environment initially, then execute the 'manage.py runserver 0.0.0.0:8000' command, we then test if Gunicorn binds to it. Once we see that Gunicorn works we then deactivate our virtual environment to start configuring Nginx. It is never mentioned to enable our virtual environment again. How is Gunicorn able to process requests when it lives inside the virtual environment, which had been deactivated? I assume there is a mechanism somewhere wherein the virtual environment is enabled again automatically. But where and when is the virtual environment enabled? I mean, how is it enabled? I've tried looking for answers online and in tutorials, but I still can't find anything that explains it fully. -

How to use postgres' ARRAY in django orm

Managing SSO for Multi-Domain and Local Deployments in a Django Application?
I am developing a Django application that will be offered in a marketplace. Each customer will have a unique domain, differentiated at least by prefixes. I have integrated Single Sign-On (SSO) for authentication. I have two specific questions regarding SSO management in this multi-domain setup: Domain Registration with SSO Providers: For each new customer, do I need to manually register each new domain with the SSO provider, or is there a method within Django or the SSO provider's services that can automate this process? Local Deployment SSO Configuration: I plan to allow customers to optionally run the application locally. I've noticed that SSO providers differ in their local testing configurations, with Google using 127.0.0.1 and Microsoft using localhost. How can I accommodate these differences in a seamless manner? Thanks in advance👍 For now I don't have any extra domains, so it is working properly...so just wanted to know about this when I try out. -
