implementing ActiveRecord callbacks preventing nested attributes from saving in Rails 6.1
I tried several approaches but none seem to work. I'm experiencing an scenario where nested attributes are not saving as expected in my Rails 6.1 application. I have a `Project` model that has many `Tasks`, and I'm using `accepts_nested_attributes_for :tasks`. Although I can see the nested attributes being passed from the form, the `Tasks` are not created or updated in the database when I validate and save the `Project` model. I've added the following code to my `Project` model: ```ruby class Project < ApplicationRecord has_many :tasks, dependent: :destroy accepts_nested_attributes_for :tasks, allow_destroy: true, reject_if: :all_blank validates :name, presence: true end ``` In my form, I have this: ```erb <%= form_with model: @project do |f| %> <%= f.text_field :name %> <%= f.fields_for :tasks do |task_fields| %> <%= task_fields.text_field :description %> <% end %> <%= f.submit 'Create Project' %> <% end %> ``` Despite this setup, when I submit the form, I receive the following behavior message: ``` ActiveRecord::RecordInvalid (Validation failed: Tasks want to be blank) ``` I’ve checked that the parameters are being sent correctly in the server logs. Here’s an example of the parameters: ``` Parameters: { "project": { "name": "New Project", "tasks_attributes": { "0": { "description": "Task 1" } } } } ``` I've also tried using `byebug` to inspect the `Project` instance before saving, and it seems like the `tasks` are indeed being initialized. However, after the save attempt, it looks like the `tasks` are empty. I've confirmed that the version of Rails I’m using is 6.1.4 and that all relevant gems are up to date. I would appreciate any help in figuring out why the nested `tasks` are not saving properly. Are there any callbacks or validations that could be interfering with the process?
