advanced patterns with Rails 7.1 Caching and ActiveRecord Validations
I recently switched to I'm stuck on something that should probably be simple. I'm experiencing some unexpected behavior with caching in Rails 7.1 when using ActiveRecord validations. I have a model `User` that performs some custom validation before saving. The validation checks if a user's email is unique and is defined as follows: ```ruby class User < ApplicationRecord validates :email, presence: true, uniqueness: true # Other model code... end ``` I am using Rails caching for some queries, and I noticed that after creating a new user, the subsequent requests for unique email validations sometimes unexpected result, allowing duplicate records to be created. The behavior message I get is `ActiveRecord::RecordInvalid: Validation failed: Email has already been taken`, but it seems like this is only happening under load, or after I have cached some results. I have tried disabling caching in my controller temporarily, and the validations work as expected. Here's how I have set up caching in my controller: ```ruby class UsersController < ApplicationController caches_action :index, cache_path: 'users/index', expires_in: 10.minutes def create @user = User.new(user_params) if @user.save redirect_to @user, notice: 'User was successfully created.' else render :new end end private def user_params params.require(:user).permit(:email) end end ``` Is there a known scenario with Rails 7.1 regarding caching interfering with ActiveRecord validations? Or could there be something in my caching strategy that I need to reconsider? Any insights would be appreciated! This is part of a larger API I'm building. Any help would be greatly appreciated! What am I doing wrong? This is happening in both development and production on Ubuntu 22.04. Thanks for any help you can provide! I'm working on a web app that needs to handle this. Is there a simpler solution I'm overlooking?
