advanced patterns with `#pluck` Method in ActiveRecord with String Columns in Rails 7
I'm running into a strange scenario when trying to retrieve specific string columns from my ActiveRecord models using the `#pluck` method in Rails 7. I have a model called `User` with fields `id`, `name`, and `email`. When I attempt to use `User.pluck(:email)` to get an array of email addresses, I sometimes get an empty array instead of the expected results. Here’s the code I’m using: ```ruby # Assuming we have some users in the database users_emails = User.pluck(:email) puts users_emails.inspect ``` The query runs without raising any errors, but when I run this in certain environments (like production), it returns an empty array. However, if I run the same query in development, it works perfectly fine. I’ve checked the database connections and configurations, and everything seems to be set up correctly. I also tried using `User.select(:email).map(&:email)` as an alternative, but that resulted in the same scenario. I suspected it might be related to caching or database state, so I cleared the cache and restarted the server, but the question continues. Is there any potential reason why `#pluck` might not return results in certain environments? Could it be linked to how data is loaded or a specific environment configuration? Any insights would be greatly appreciated. This is part of a larger REST API I'm building. Hoping someone can shed some light on this.
