How to implement 'undefined method `pluck` for ActiveRecord::Relation' in Rails 7 with PostgreSQL?
I'm sure I'm missing something obvious here, but I'm integrating two systems and Can someone help me understand I tried several approaches but none seem to work. I'm working on a Rails 7 application using PostgreSQL as my database. I recently updated my gemfile and now, while trying to retrieve certain attributes from my User model, I'm working with the behavior: `undefined method 'pluck' for ActiveRecord::Relation`. Here’s the code snippet that’s causing the scenario: ```ruby # app/models/user.rb class User < ApplicationRecord # Associations and validations... end ``` And then in my controller, I'm trying to fetch specific user emails like this: ```ruby # app/controllers/users_controller.rb class UsersController < ApplicationController def index @user_emails = User.all.pluck(:email) # This is where the behavior occurs end end ``` I have verified that the `email` column exists in the `users` table. Initially, I thought it might be a gem scenario, so I re-checked my Gemfile and run `bundle install`, but the behavior continues. Here’s the relevant part of my Gemfile: ```ruby # Gemfile gem 'rails', '~> 7.0' gem 'pg' ``` I also checked my database configuration in `config/database.yml`, and it looks fine: ```yaml development: <<: *default database: my_app_development ``` What could be causing this scenario? Is there a compatibility question with ActiveRecord and PostgreSQL in Rails 7 that I need to be aware of? Any guidance on how to resolve this would be greatly appreciated. I'm on Windows 10 using the latest version of Ruby. Am I approaching this the right way? Thanks, I really appreciate it! My development environment is Linux. Any examples would be super helpful. Could this be a known issue?
