working with NoMethodError when trying to use delegation in Rails 7
I'm working through a tutorial and I'm upgrading from an older version and I've been researching this but After trying multiple solutions online, I still can't figure this out..... I'm sure I'm missing something obvious here, but I'm working with a `NoMethodError` when attempting to delegate methods in my Rails 7 application... In my model, I have a `User` model that has one `Profile`. I'm trying to delegate `full_name` from `Profile` to `User` so that I can call `@user.full_name` directly. Here's how I've set things up: ```ruby class User < ApplicationRecord has_one :profile delegate :full_name, to: :profile end class Profile < ApplicationRecord belongs_to :user def full_name "#{first_name} #{last_name}" end end ``` I've also ensured that the `Profile` is being created correctly when I create a `User`. For example: ```ruby @user = User.create(email: 'test@example.com', profile_attributes: { first_name: 'John', last_name: 'Doe' }) ``` However, when I try to access `@user.full_name`, I'm getting this behavior: ``` NoMethodError: undefined method `full_name' for nil:NilClass ``` I've double-checked that `@user.profile` is indeed being created, but when I check it with `@user.profile.nil?`, it returns `true`. I thought that using `accepts_nested_attributes_for :profile` would automatically build the profile when I create the user. I've added the following to my `User` model: ```ruby accepts_nested_attributes_for :profile ``` But it seems like the profile is not being saved as part of the user creation process. Am I missing something with the nested attributes or the delegation? Any insights would be appreciated. Has anyone else encountered this? I'm working on a mobile app that needs to handle this. Am I approaching this the right way? The stack includes Ruby and several other technologies. Any examples would be super helpful. I'm working with Ruby in a Docker container on CentOS. Has anyone dealt with something similar? I'm working in a CentOS environment. I'd really appreciate any guidance on this.
