我在将类 Group 的对象实例保存到数据库时遇到问题
请帮助我了解问题出在哪里
这是模型
class User < ActiveRecord::Base
has_many :groups
end
class Group < ActiveRecord::Base
belongs_to :user
has_many :people
end
和路线.rb
resources :users do |user|
resources :groups do |group|
resources :people
end
end
我使用 Devise 构建用户模型和认证系统
用例：用户注册，现在他/她可以创建组。如果用户未注册和登录，则不允许创建组。这部分有效。
然后用户转到 new_user_group_path，填写表格并单击创建。此时页面刷新，我看到相同的表单（空）和 url，其中包含在 previos 步骤中填充表单的所有参数。像这样users/user_id/groups/new?utf8=✓&authenticity_token=...
同时列表user_groups_path不显示任何新对象
这是 Group 的控制器
class GroupsController < ApplicationController
respond_to :html, :xml, :json
before_filter :authenticate_user!
def new
@user = current_user
@group = @user.groups.build(:user_id => current_user.id,
:location=>params[:group][:location])
respond_with(@group)
end
def create
@user = current_user
@group = @user.groups.build(:user_id => current_user.id,
:location=>params[:group][:location])
if @group.save
redirect_to user_groups_path(current_user)
else
render 'new'
end
end
这是表格
<%= form_for @group, :url => user_groups_path(:user_id => current_user.id) do |f| %>
<% if @group.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@group.errors.count, "error") %> prohibited this group from being saved:</h2>
<ul>
<% @group.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= f.label :location %>
<%=f.text_field :location %>
<etc...>
<% end %>
UPD 的结果rake routes
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session GET /users/sign_out(.:format) devise/sessions#destroy

user_group GET /users/:user_id/groups/:id(.:format) groups#show
PUT /users/:user_id/groups/:id(.:format) groups#update
DELETE /users/:user_id/groups/:id(.:format) groups#destroy
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
数据库是 sqlite3
我哪里错了？
感谢任何帮助

/users/:user_id/groups/new这是在页面上生成的 HTML ：
