Rails 7.1: Unexpected ActiveRecord::RecordInvalid scenarios when saving nested attributes
I'm refactoring my project and Quick question that's been bugging me - I'm working with an scenario when trying to save a model with nested attributes in Rails 7.1... I have a `Project` model that has many `Tasks`, and I'm attempting to create both a project and its associated tasks through a single form submission. However, I'm getting an `ActiveRecord::RecordInvalid` behavior when the `Project` is saved, even though it seems like the parameters being sent are valid. Here’s a snippet of my `Project` model: ```ruby class Project < ApplicationRecord has_many :tasks, dependent: :destroy accepts_nested_attributes_for :tasks, allow_destroy: true validates :name, presence: true end ``` And here’s the relevant part of my form: ```erb <%= form_with(model: @project, local: true) do |f| %> <%= f.label :name %> <%= f.text_field :name %> <%= f.fields_for :tasks do |task_form| %> <%= task_form.label :description %> <%= task_form.text_field :description %> <% end %> <%= f.submit %> <% end %> ``` The parameters being sent look like this: ```ruby { "project": { "name": "New Project", "tasks_attributes": { "0": { "description": "Task 1" }, "1": { "description": "Task 2" } } } } ``` When I try to save, I receive this behavior: ``` ActiveRecord::RecordInvalid (Validation failed: Tasks description need to be blank) ``` I've confirmed that the `description` field is indeed being sent in the parameters. I even added a simple validation to ensure the presence of the task's description: ```ruby class Task < ApplicationRecord belongs_to :project validates :description, presence: true end ``` I've checked that the `tasks` are being initialized properly and I can see them in the console when I debug. However, I need to seem to understand why Rails is throwing a `RecordInvalid` behavior. I thought it may be an scenario with strong parameters, so I have the following in my controller: ```ruby def project_params params.require(:project).permit(:name, tasks_attributes: [:description, :_destroy]) end ``` Any insights on what might be going wrong here? I would really appreciate any help in tracking down this scenario as it’s blocking my development process. This is for a service running on Ubuntu 20.04. I appreciate any insights!
