我有一个有多个计划的应用。对于＆＃34;团队＆＃34;计划，用户将输入团队名称和许可证计数。创建用户后，将保存新团队。我想我的数据库部分是正确的，但我对如何创建团队感到困惑。更具体地说，我的问题是：1）如何将团队字段添加到视图中？我是否在用户表单中使用form_for并嵌套？ 2）如何在控制器中处理团队创建？谢谢你的帮助。
迁移：
class CreateTeams < ActiveRecord::Migration
def change
create_table :teams do |t|
t.string :team_name
t.integer :license_count
t.timestamps
end
add_column :users, :team_id, :integer, :null => true
add_column :users, :team_admin, :boolean
end
end
控制器：
class RegistrationsController < Devise::RegistrationsController
def new
return if plan_missing
build_resource({})
self.resource.plan = params[:plan]
respond_with self.resource
end
protected
#after user has signed up
def after_inactive_sign_up_path_for(resource)
new_user_session_path
end
#after user has updated their profile, keep them on the same page
def after_update_path_for(resource)
edit_user_registration_path
end
private
def plan_missing
if params[:plan].nil?
redirect_to plans_path
true
else
false
end
end
def log
logger.debug @user.to_yaml
logger.debug params.to_yaml
