Is it possible to write to a Firestore Real Time Database with Django?
I don't want to use Firestore as my primary data store, rather I want to write information to the Firestore and for that information to be then parsed/used by an iOS app. Example: I create a Django app that allows me to submit forms containing information that is saved to the Firestore DB. I save a copy of this form submission in my Django relational database, and a copy is submitted and saved to my Firestore DB. That data is then picked up by my iOS app which is using Firestore as it's primary data store. Is this something that's easily done? Will I face any problems in attempting to create this? Thanks -

macOS terminal doesn't create files in right directory
I wanted to use virtual Django environment with pipenv. I created a file named djangotest in my desktop. I accessed it in terminal using cd ~/Desktop/djangotest then I ran pipenv install django and it says it installed successfully. I opened the djangotest folder and didn't see pipfile and pipfile.lock . Then I saw that pipfile and pipfile.lock was created on my Desktop instead of the directory I wanted them to install on.

Django order_by on custom model method
I have the following model: class Transactions(models.Model): transaction_amount = models.DecimalField(max_digits=65, decimal_places=0, default=0) decimals = models.PositiveSmallIntegerField("Decimals", null=True, blank=True) def amount_convert(self): try: converted = transaction_amount / pow(10, decimals) except Exception: return None Because transaction may contain different currency, each currency has different decimal value I tried to use the query Transactions.objects.filter(...).order_by('-transaction_amount') but realized i have special case with different currencies For example: IN DB: id=1, transaction_amount = 200000, decimals = 4 => amount_convert() = 20 id=2, transaction_amount = 10000000, decimals = 6 => amount_convert() = 10 is id=1 should be on top of id=2 but the transaction_amount i'm querying is wrong So the amount_convert() model method is what i'm looking for when using order_by(), but seems like order_by doesn't support custom model method. Is there a way i can use custom model method for sorting in query? -
