how to access nested attributes for associated models in Rails 7 with accepts_nested_attributes_for
I keep running into I'm stuck trying to After trying multiple solutions online, I still can't figure this out. I'm having issues with managing nested attributes in my Rails 7 application. I have a `Project` model that `has_many` `Tasks`, and I'm trying to allow the creation of `Tasks` through a form for the `Project`. I've added `accepts_nested_attributes_for :tasks` in my `Project` model, but when I submit the form, I'm getting the behavior: `Tasks is invalid`. Here’s what my `Project` model looks like: ```ruby class Project < ApplicationRecord has_many :tasks, dependent: :destroy accepts_nested_attributes_for :tasks, allow_destroy: true end ``` And my `Task` model is quite simple: ```ruby class Task < ApplicationRecord belongs_to :project validates :name, presence: true end ``` In my form, I have this structure: ```erb <%= form_with model: @project do |f| %> <%= f.label :name %> <%= f.text_field :name %> <%= f.fields_for :tasks do |task_fields| %> <%= task_fields.label :name %> <%= task_fields.text_field :name %> <%= task_fields.check_box :_destroy %> <%= task_fields.label :_destroy, 'Remove Task' %> <% end %> <%= f.submit 'Save Project' %> <% end %> ``` When I submit the form, I check the parameters sent, and they look like this: ```ruby { "project": { "name": "New Project", "tasks_attributes": { "0": { "name": "Task 1", "_destroy": "false" } } } } ``` I’ve verified that the `tasks_attributes` key is present, but I still see the behavior. I've also tried using the `debug` and `puts` statements to log the errors, and I'm seeing `Tasks is invalid` without any additional details. I've checked for typos in attribute names and confirmed that the strong parameters are correctly set in my controller: ```ruby class ProjectsController < ApplicationController def project_params params.require(:project).permit(:name, tasks_attributes: [:id, :name, :_destroy]) end end ``` It seems like everything is set up correctly, but something is still not working. Has anyone encountered this scenario or can provide insights into what I might be missing? For context: I'm using Ruby on Ubuntu. My development environment is macOS. Any advice would be much appreciated. This issue appeared after updating to Ruby 3.10. Any pointers in the right direction?
