Undefined method in User model

I am a beginner in rails, and I'm having an issue in a registration form.

I have users and emails in different tables (take a look) but the user registration form has an email field mixed with all the other fields such as username and password.

At first render there's no issue, but when trying to save, if any error occurs (such as duplicated username or email) I follow steps here, where it says (don't redirect_to, just do render 'new' to keep previously inserted info. That's when it throws an error saying email is not known.

I don't want to create the field email in the users table, since I already removed it from the original model. How do I fix that?

Form code

<%= form_for :user, url: users_path do |f| %>
<p>
  <%= f.label :username %>
  <%= f.text_field :username %>
</p>
<p>
  <%= f.label :name %>
  <%= f.text_field :name %>
</p>
<p>
  <%= f.label :email %>
  <%= f.email_field :email # Error is thrown in this line %>
</p>
<p>
  <%= f.label :password %>
  <%= f.password_field :password %>
</p>
<p>
  <%= f.label :password_confirmation %>
  <%= f.password_field :password_confirmation %>
</p>
<p>
  <%= f.submit %>
</p>

Controller code

def create
  # render plain: params[:user].inspect
  @user = User.new(user_registration_params)
  if @user.save
    email_params = {email: params[:user][:email], primary: true}
    @email = Email.new(email_params)
    @email.user = @user
    if @email.save
      redirect_to @user
    else
      @user.destroy
    end
  else
    render 'new'
  end
end

If you have connected the both models via belongs_to you can set up your form to update/create both models.

You have to declare you user with accepts_nested_attributes_for.

See a full example here:
