我正在为一个运动队工作一个rails 4 API,我有球员和球队,而且我在使用rails路由和has_many
关系方面苦苦挣扎。我和球员之间的关系看起来像是:
class Team < ActiveRecord::Base
extend Searchable
validates :title, presence: true
has_and_belongs_to_many :players
end
class Player < ActiveRecord::Base
extend Searchable
validates :first_name, presence: true
validates :last_name, presence: true
has_and_belongs_to_many :teams
end
我希望能够将现有的播放器添加到团队中,但我不确定如何更改我的routes.rb
文件。目前,它看起来像:
Rails.application.routes.draw do
devise_for :users
namespace :api, defaults: { format: :json },
constraints: { subdomain: 'api' }, path: '/' do
scope module: :v1 do
resources :users, :only => [:show, :create, :update, :destroy]
resources :teams, :only => [:show, :create, :update, :destroy, :index]
resources :players, :only => [:show, :create, :update, :destroy, :index]
resources :sessions, :only => [:create, :destroy]
end
end
end
允许对玩家和团队模型进行CRUD操作。我在考虑将球员添加到现有球队,我的路线需要看起来像:
/teams/:team_id/add_player/
但我不确定如何在routes.rb
中声明该路线。所以,有几个问题:
routes.rb
感谢您提供的任何帮助,

您需要使用nested resource:
#config/routes.rb
resources :teams, only: [....] do
resources :players, path: "", path_names: {new: "add_player", create: "add_player", destroy: "remove_player" }, only: [:create, :destroy] #-> /v1/teams/:team_id/add_player
end
这会路由到players_controller
,并传递:team_id
参数:
#app/controllers/players_controller.rb
class PlayersController < ApplicationController
def new
@players = Player.all
end
def create
if params[:team_id]
@team = Team.find params[:team_id]
@player = Player.find params[:id]
@team.players << player
else
# normal "create" action
end
end
def destroy
if params[:team_id]
@team = Team.find params[:id]
@player = Player.find params[:id]
@team.players.delete player
end
end
end
您可以将其与以下视图结合使用:
#app/views/players/new.html.erb
<%= form_tag team_players_path do %> #-> method should be "post"
<%= collection_select :player, :id, @players, :id, :name %>
<%= submit_tag %>
<% end %>

使用HABTM,您可以获得<<
&amp; collection.delete
方法 - 允许您简单地添加和删除集合中的对象。

从REST-ful的角度来看,这条路线对人们有意义吗?如果是,我将如何在
中声明此路线routes.rb
是的。
将球员添加到球队应该是PATCH还是POST方法?
与资源丰富的路由结构一致,我会说您可以通过POST
操作获取create
请求,但可以通过多种方式完成!
这样做:
#config/routes.rb
resources :teams, only: [....] do
match "players/:id", to: "players", via: [:put, :delete]
end
这将创建以下路线:
#put url.com/teams/:team_id/players/:id
#destroy url.com/teams/:team_id/players/:id
这样您就可以在players
控制器中使用teams
方法:
#app/controllers/teams_controller.rb
class TeamsController < ApplicationController
def players
@team = Team.find params[:team_id]
@player = Player.find params[:id]
if request.put?
@team.players << player
elsif request.delete?
@team.players.destroy player
end
end
end
答案 1 :(得分:1)
您可以这样声明此路线:
resources :teams, only: [:show, :create, :update, :destroy, :index] do
put 'add_player', on: :member
end
它会将路线映射到add_player
中的TeamsController
操作。
从REST-ful的角度来看,我建议你在players#update
动作中进行此操作,因为你基本上是在改变玩家记录。
