Calculate the Average delivery time (days) Django ORM
I want to calculate the average delivery time (in days) of products using ORM single query (The reason of using single query is, I've 10000+ records in db and don't want to iterate them over loops). Here is the example of models file, I have: class Product(models.Model): name = models.CharField(max_length=10) class ProductEvents(models.Model): class Status(models.TextChoices): IN_TRANSIT = ("in_transit", "In Transit") DELIVERED = ("delivered", "Delivered") product = models.ForiegnKey(Product, on_delete=models.CASCADE) status = models.CharField(max_length=255, choices=Status.choices) created = models.DateTimeField(blank=True) To calculate the delivery time for 1 product is: product = Product.objects.first() # delivered_date - in_transit_date = days_taken duration = product.productevent_set.filter(status='delivered') - product.productevent_set.filter(status='in_transit') I'm here to get your help to getting started myself over this so, that I can calculate the average time between all of the Products. I'd prefer it to done in a single query because of the performance. -

The deployment worked fine (website running) besides the fact that tailwind won't work. Please forgive me if my question is dumb, it is my first project using tailwind. I have made sure that node.js version and npm version are the same on my local environment and on my ubuntu server but I am still getting the issue. From the django-tailwind documentation https://django-tailwind.readthedocs.io/en/latest/usage.html , getting tailwind to deployment was the following command. python manage.py tailwind build doing that on my production server outputs the following error: node:internal/modules/cjs/loader:939 const err = new Error(message); ^ Error: Cannot find module 'semver' Require stack: - /usr/share/nodejs/npm/lib/utils/unsupported.js - /usr/share/nodejs/npm/lib/cli.js - /usr/share/nodejs/npm/bin/npm-cli.js at Module._resolveFilename (node:internal/modules/cjs/loader:939:15) at Module._load (node:internal/modules/cjs/loader:780:27) at Module.require (node:internal/modules/cjs/loader:1005:19) at require (node:internal/modules/cjs/helpers:102:18) at Object.<anonymous> (/usr/share/nodejs/npm/lib/utils/unsupported.js:2:16) at Module._compile (node:internal/modules/cjs/loader:1105:14) at Module._extensions..js (node:internal/modules/cjs/loader:1159:10) at Module.load (node:internal/modules/cjs/loader:981:32) at Module._load (node:internal/modules/cjs/loader:827:12) at Module.require (node:internal/modules/cjs/loader:1005:19) { code: 'MODULE_NOT_FOUND', requireStack: [ '/usr/share/nodejs/npm/lib/utils/unsupported.js', '/usr/share/nodejs/npm/lib/cli.js', '/usr/share/nodejs/npm/bin/npm-cli.js' ] } Node.js v18.2.0 that is strange because I installed it and still won't find it: which semver /usr/local/bin/semver and 2.

Building a website to query large datasets in database
I have downloaded filings from the SEC website and created code to parse the txt files into DataFrames in Pandas. The data contains approximately 13M lines of records so I have exported the data to a CSV file on my local drive. I would like to be able to build a website similar to that of a Bloomberg Terminal where I can query the data from any location (other than my local computer). What would be the best way to store this data (MS Access has size limitations, Oracle maybe? MySQL?) to be able to build an interface to manipulate this data? Building a website from scratch is no small feat so any suggestions/advice would be appreciated.
