will check it out thanks!

I am getting same issue.

@chris, I just finished video #5 of the Chatrooms tutorial. Everything looks ok in terminal output, but when I hit 'enter' key after typing a message I still have to refresh browser to see the message appear. Here is repo: https://github.com/rmindigo/chat_demo_gorails Any ideas why message doesn't appear instantly? Terminal output below. Thanks!

Same error for me. Will just press on and hope things work when we addd ActionCable.

got the answer, needed to add one line to the new action in AccountsController

@account.users.build

have you tried this? or some variation of dependent: :destroy on the model associations

has_many :students, through: :attendances, source: :student, dependent: :destroy

https://guides.rubyonrails.org/association_basics.html

I think you want do run a callback: https://guides.rubyonrails.org/active_record_callbacks.html

Hello! I am building an app with Accounts/Users & Memberships via has_many through. I am using Devise and want to create a new user from 'accounts#new" via 'accepts_nested_attributes_for.'

When I fill out the form to create a new Account & User, the Account is being created, but no User. I am seeing 'unpermitted parameter: :user.'

I assume there is something missing in my Controller. Here is the terminal output and code below.

I am able to successfully create a new Account and User in console
