如何在rails中处理替代的create方法

class UsersController < ApplicationController
  def custom_create
    # 自定义的create逻辑
    @user = User.new(user_params)
    if @user.save
      # 保存成功的处理
      redirect_to @user
    else
      # 保存失败的处理
      render 'new'
    end
  end

  private

  def user_params
    params.require(:user).permit(:name, :email, :password)
  end
end

Rails.application.routes.draw do
  resources :users do
    collection do
      post 'custom_create', to: 'users#custom_create'
    end
  end
end

<%= form_for @user, url: custom_create_users_path do |f| %>
  <!-- 表单字段 -->
  <%= f.text_field :name %>
  <%= f.email_field :email %>
  <%= f.password_field :password %>
  <%= f.submit 'Create User' %>
<% end %>
