Devise Unpermitted parameter nested form - forms

Question

I have a user model parent and and child model patient. I want to add patient related attributes in the patients model through devise(user) signup form, but the data is not saving in patient model.
class RegistrationsController < Devise::RegistrationsController
def new
build_resource({})
resource.build_patient
respond_with self.resource
end
def create
super
end
end
private
def sign_up_params
params.require(resource_name).permit(:email, [patient_attributes:[:user_id, :phone, :address,:age]], :password, :password_confirmation)
end
This is my user and patient models:
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_one :patient
accepts_nested_attributes_for :patient
end
#####
class Patient < ActiveRecord::Base
belongs_to :user
end
This is the nested form:
<div class="field">
<%= f.fields_for :patient do |p| %>
phone <%= p.text_field :phone %>
address <%= p.text_field :address %>
age <%= p.text_field :age %>
<%end%>
</div>
When I fill the form and click submit button these are the params:
Parameters: {"utf8"=>"✓", "authenticity_token"=>"b+5GjScdG1gSnPL1eRDMW9U6tWiL1+liJMHvBCWYO2DEqRPJIBKzpXE3HGHlDgJPVcB+ro3ZVi+fHmNCdri1Zw==", "user"=>{"username"=>"q", "email"=>"kh1#gmail.com", "patient_attributes"=>{"phone"=>"444444", "address"=>"lllllllll", "age"=>"55"}, "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "user_type"=>"1"}, "commit"=>"Sign up"}
**Unpermitted parameter: patient_attributes**

Answer 1

So the answer is simple
i add parameters is like this in application controller
devise_parameter_sanitizer.permit(:sign_up) do
|u| u.permit(:email, :password, :password_confirmation, :username,:user_type,patient_attributes: [:user_id, :phone, :address,:age])
end
and change form little bit
<div class="field">
<%= f.fields_for :patient, Patient.new do |p| %>
</br>
phone <%= p.text_field :phone %>
</br>
address <%= p.text_field :address %>
</br>
age <%= p.text_field :age %>
<%end%>
</div>

This might help you.
Just remove square bracket from [patient_attributes:[:user_id, :phone, :address,:age]]
and use
patient_attributes:[:user_id, :phone, :address,:age]
only. This should help you.
