Rails 7.1: implementing STI and Scopes Leading to Unexpected Query Results
I'm attempting to set up I'm stuck on something that should probably be simple. I'm updating my dependencies and I'm currently working on a Rails 7.1 application that uses Single Table Inheritance (STI) for a `User` model. I have different user types: `Admin`, `Manager`, and `Customer`. Each type has specific scopes that I defined to filter records according to user roles. However, when I try to query the `User` model using these scopes, I get unexpected results. Here's the model setup: ```ruby class User < ApplicationRecord scope :admins, -> { where(type: 'Admin') } scope :managers, -> { where(type: 'Manager') } scope :customers, -> { where(type: 'Customer') } end class Admin < User; end class Manager < User; end class Customer < User; end ``` I've tried using the scopes like this: ```ruby users = User.admins ``` But when I call `users.count`, it returns a count that includes both `Admin` and `Manager` users. The SQL generated looks something like this: ```sql SELECT COUNT(*) FROM users WHERE type = 'Admin'; ``` Despite this seemingly correct SQL, the result is incorrect. I've confirmed that the database has the correct records, so I suspect there might be something related to caching or the way Rails handles STI queries. Also, I have some debugging statements, and I see that the correct SQL is executed, but the count is not accurate. I've tried clearing the Rails cache with `rails cache:clear` and also checked if there are any overrides in the `application.rb` that could affect the behavior. Nothing seems to help. Have you encountered similar issues with STI and scopes in Rails 7.1? Any insights on how to resolve this discrepancy would be greatly appreciated! For context: I'm using Ruby on Linux. Am I missing something obvious? I'm working with Ruby in a Docker container on Windows 11. I'm open to any suggestions. I'm developing on CentOS with Ruby. Thanks in advance! I'm working on a microservice that needs to handle this. I'd be grateful for any help.
