How to handle ActiveRecord validation on nested attributes in Rails 6?
I'm prototyping a solution and I'm experimenting with I'm currently working on a Rails 6 application where I have a `Project` model that has many `Tasks`... Each `Task` has some validations that are dependent on the parent `Project` being valid. I'm trying to use nested attributes for `Tasks`, but I'm working with an scenario where the parent validation causes the nested attributes to not save properly, and I get errors like `Tasks is invalid` even when the parent `Project` is valid. Here's the relevant part of my code: ```ruby class Project < ApplicationRecord has_many :tasks, dependent: :destroy accepts_nested_attributes_for :tasks, allow_destroy: true validates :name, presence: true end class Task < ApplicationRecord belongs_to :project validates :description, presence: true end ``` In my form, I'm using simple_form for the parent and nested attributes: ```erb <%= simple_form_for @project do |f| %> <%= f.input :name %> <%= f.simple_fields_for :tasks do |task_form| %> <%= task_form.input :description %> <% end %> <%= f.button :submit %> <% end %> ``` When I submit the form with an empty description for the `Task`, I see the behavior messages on the `Project` object instead of the `Tasks`. I've tried wrapping the tasks in a conditional validation block based on the project's state, but that doesn't seem to be fixing the scenario. I've also checked that I have strong parameters set up correctly in the controller: ```ruby class ProjectsController < ApplicationController def project_params params.require(:project).permit(:name, tasks_attributes: [:id, :description, :_destroy]) end end ``` Any guidance on how to properly manage validations for nested attributes in this scenario would be greatly appreciated! Is there a way to ensure that the errors for `Tasks` are displayed properly without affecting the `Project` validation? Thanks in advance! The project is a service built with Ruby. I'm using Ruby 3.10 in this project. What am I doing wrong? This is happening in both development and production on macOS. Thanks, I really appreciate it! Any suggestions would be helpful.
