How to make rails associations work

Kasper Valentin asked in Rails

I have this set up, but noting gets saved to the db when I try to save a practitioner.
The tables are users, clinics and practitioners. The user should be able to create multiple clinics and each clinic should be able to add multiple practitioners to the specific clinic.

I can't seem to figure out, what I should do to make it work. I can see it says that user.rb is missing practitioners_attribute
but practitioners is associated to clinic and not user, that's why I've put it in clinic.rb, and even if I put accepts_nested_attributes_for :practitioners, reject_if: :all_blank, allow_destroy: true in user.rb it still doesn't work.

I get this error:
ActiveModel::UnknownAttributeError in RegistrationStepsController#update
unknown attribute 'practitioners_attributes' for User.
@user = current_user
# Change @user.attributes(user_params) by @user.update_attributes(user_params)
@user.update_attributes(user_params)
render_wizard @user
end

This is how I have tried to make it work so far:

User has many clinics

clinics belongs to user

clinics has many practitioners

practitioners belongs to clinics

I’ve added a foreign user key to connect clinics table with users table

I’ve added a foreign clinic key to connect practitioners table with clinics table

user.rb

class User < ApplicationRecord        
has_many :clinics, dependent: :destroy
accepts_nested_attributes_for :clinics, reject_if: :all_blank, allow_destroy: true
end

clinic.rb

class Clinic < ApplicationRecord
belongs_to :user
has_many :practitioners
    accepts_nested_attributes_for :practitioners, reject_if: :all_blank, allow_destroy: true
end

practitioner.rb

class Practitioner < ApplicationRecord
belongs_to: clinic
end

add clinics foreign key to practitioners

class AddClinicReferenceToPratitioners < ActiveRecord::Migration[5.2]
def change
add_reference :practitioners, :clinic, foreign_key: true
end
end

add users foreign key to clinics

class AddUserReferenceToClinics < ActiveRecord::Migration[5.2]
def change
add_reference :clinics, :user, foreign_key: true
end
end

I fixed it by changing the params from

    clinics_attributes: [:id, :clinic_logo, :clinic_name, :clinic_address, :clinic_zip_code, :clinic_municipality, :clinic_about, :clinic_mail, :clinic_phone, :clinic_website, :clinic_city, :_destroy],
        practitioners_attributes: [:id, :practitioner_first_name, :practitioner_last_name, :practitioner_description, :practitioner_mail, :practitioner_phone, :practitioner_website, :_destroy])

end

to

clinics_attributes: [:id, :clinic_logo, :clinic_name, :clinic_address, :clinic_zip_code, :clinic_municipality, :clinic_about, :clinic_mail, :clinic_phone, :clinic_website, :clinic_city, :_destroy,
    practitioners_attributes: [:id, :practitioner_first_name, :practitioner_last_name, :practitioner_description, :practitioner_mail, :practitioner_phone, :practitioner_website, :_destroy]])
