Using GCS for media storage on Railway.app
I'm deploying my Django app to Railway.app and am hosting media on GCS (I like the free tier). I've created the service account and received the .json of the credentials. On my local system for dev, I have the .json file in the directory and refer to it like this: GS_CREDENTIALS = service_account.Credentials.from_service_account_file(".gcs_credentials.json") No problems and files upload great. I'm not passing the credentials file through Github (for safety reasons) but now I'm stuck. Is there a way to save this JSON file as an environment variable in Railway.app? For all of my other variables, I'm using django-environ and everything is working great. I just can't find anything online about passing credentials in JSON form to a deployment on Railway. Thank you in advance. -
Where does Django check framework functions live?
The django framework allows you to write your own checks https://docs.djangoproject.com/en/4.2/topics/checks/ but it says nothing about where that code should live and how it is hooked into the check framework. Any ideas on how this is done? -
Django Follow / Unfollow button does not change

Using list elements in a form in Django template
I have the following form in a Django template. The list prize is a list of numbers defined in my view.py. Specifically, prize is defined to be prize = [0]*total I want to have the elements of prize listed as the default values on user input fields. I have tried to do this with the following code. <form> {% for i in total %} <label for="match_{{ i }}">Enter the prize received for getting {{ i }} matches:</label> <input type="number" name="match_{{ i }}" id="match_{{ i }}" required value="{{ prize.i|default:'' }}"> <br> {% endfor %} </form> While I get no errors, I only get the empty forms with no default values. Any ideas? I have checked that the list prize is rendered correctly as I can print out their values on the webpage fine. -

Odd behavior concerning Django's admin page saving files
I have Django 4.1.7 website, served by apache2 on Ubuntu PC. in the .conf file of apache2: Alias /static /mnt/hdd/SIMSY/static/ and Django works as expected. All CSS, JS, Images are loaded just fine. But when adding new object using Django's built-in admin site, the site tries saving the images on /static in the root of Ubuntu (it caused Permission error, then I tried creating that folder in the root and it actually saved the image in that folder). How is Django trying to save in /static while apache2 tells it that /static is /mnt/hdd/SIMSY/static? I assume there is something can be changed in settings.py to solve that, what can be changed? Here is the part of settings.py that has anything to do with static: BASE_DIR = Path(__file__).resolve().parent.parent STATIC_URL = '/static/' STATICFILES_DIRS = [ BASE_DIR / "static", ] -

Change IP-address of django server [closed]

How to dynamically generate optimal zoom on folium/leaflet?
I am using leaflet and folium to map out locations. These locations can be filtered out and therefore requires something a bit dynamic. I want to achieve two things: center the user on the map between the different locations (that works); Now I also want to regulate the zoom level to capture all the locations on the screen - sometime this zoom might be at street level, sometimes it might be at a country level. I feel my problem can be solved by using fitBounds, which according to documentation automatically calculates the zoom to fit a rectangular area on the map. That sounds ideal and this post here seems to be giving an answer about a similar question: pre-determine optimal level of zoom in folium Slight problem, I just don't understand it. I am thinking I should be able to use the min and max longitude and latitude to generate the rectangular area leaflet documentation refers to. But how does that translate in the zoom levels provided by leaflet? def function(request): markers = Model.objects.filter(location_active=True) #Max latitude & longitude min_latitude = Model.objects.filter(location_active=True).aggregate(Min('latitude'))['latitude__min'] min_longitude = Model.objects.filter(location_active=True).aggregate(Min('longitude'))['longitude__min'] #Min latitude & longitude max_latitude = Model.objects.filter(location_active=True).aggregate(Max('latitude'))['latitude__max'] max_longitude = Model.objects.filter(location_active=True).aggregate(Max('longitude'))['longitude__max'] sum_latitude = 0 # sum latitude … -

Django build Models with duplicating data is a correct way?
I'm new to Django. But have a doubt now regarding building Models within one Django app with certain relations. For example I have an accounts app with defined model User(AbstractUser) which works fine. I've created a new Django app records with a model Bill which suppose to handle a certain service records with following fields: year_due service_name cost To link User with a Bill I've created an additional model Payment which contains: user_id bill_id service_name year_due Is this example a good practice to define models or better to incapsulate such a fields within one class? I want to make it clear to see the relevant data. The main idea is to clearly see to which service_name a certain bill or payment belong. The raw example of my code I haven't yet migrate: class Bill(models.Model): service_name = models.CharField(max_length=30) fixed_cost = models.BooleanField(default=False) unit = models.CharField(max_length=5, null=True, blank=True) current_counter = models.DecimalField(max_digits=15, decimal_places=2, null=True, blank=True) consumption = models.DecimalField(max_digits=8, decimal_places=2, null=True, blank=True) cost_per_unit = models.DecimalField(max_digits=6, decimal_places=2, null=True, blank=True) payed_amount = models.DecimalField(max_digits=8, decimal_places=2) is_paid = models.BooleanField(default=False) class Payment(models.Model): bill_id = models.ForeignKey(Bill, on_delete=models.CASCADE) user_id = models.ForeignKey(User, on_delete=models.CASCADE) record_date = models.DateTimeField(auto_now_add=True) service_name = models.CharField(max_length=30) year_due = models.IntegerField() month_due = models.IntegerField() payed_amount = models.DecimalField(max_digits=8, decimal_places=2) Thank You in advance …
