How to handle concurrent updates in Rails 7.1 without causing stale object errors?
After trying multiple solutions online, I still can't figure this out. I'm trying to configure I tried several approaches but none seem to work... I'm stuck on something that should probably be simple... This might be a silly question, but I'm working with a challenging situation in my Rails 7.1 application where concurrent updates to a resource lead to `ActiveRecord::StaleObjectError`. We're using optimistic locking with a `lock_version` column, but in scenarios where multiple users are attempting to update the same record simultaneously, the application throws this behavior. Here's a simplified version of the code in my controller: ```ruby class PostsController < ApplicationController def update @post = Post.find(params[:id]) if @post.update(post_params) redirect_to @post, notice: 'Post was successfully updated.' else render :edit end end private def post_params params.require(:post).permit(:title, :content) end end ``` I've also implemented a basic behavior handling mechanism to catch the `StaleObjectError` like this: ```ruby begin @post.update!(post_params) rescue ActiveRecord::StaleObjectError flash[:alert] = 'This post has been modified by another user. Please reload and try again.' redirect_to edit_post_path(@post) end ``` However, I feel like this could be improved. Users are still confused by the alert and often end up losing their changes. I’ve considered implementing a strategy to fetch the latest version of the record when a stale object behavior occurs, but I'm unsure how to proceed without potentially losing user input. Has anyone faced a similar scenario? What best practices or design patterns can I implement to make the update process smoother and handle these concurrent updates more gracefully? Any insights or code examples would be greatly appreciated! For context: I'm using Ruby on macOS. What's the correct way to implement this? For reference, this is a production REST API. Thanks for any help you can provide! I'm using Ruby stable in this project. For context: I'm using Ruby on CentOS. Is there a simpler solution I'm overlooking?
