在 ruby on Rails 中查询关系并通过 Ajax 更新结果
我有一个 ROR 应用程序,其中有很多玩家和许多提议的游戏。游戏显示在提要上,玩家可以决定从该提要中隐藏它们。隐藏函数的工作原理如下:
在player.rb中:
has_many :hides, :foreign_key=> "hider_id",
:dependent => :destroy
has_many :hidees, :through => :hides
def hidden?(hidee)
hides.find_by_hidee_id(hidee)
end
def hide!(hidee)
hides.create!(:hidee_id => hidee.id)
end
def unhide!(hidee)
hides.find_by_hidee_id(hidee).destroy
end
hides_controller.rb
class HidesController < ApplicationController
def create
@game = Game.find(params[:hide][:hidee_id])
current_profile.hide!(@game)
redirect_to :back
end
def destroy
@game = Hide.find(params[:id]).hidee
current_profile.unhide!(@game)
redirect_to :back
end
end
hide.rb
class Hide < ActiveRecord::Base
attr_accessible :hidee_id
belongs_to :hider, :class_name => "Player"
belongs_to :hidee, :class_name => "Game"
validates :hider_id, :presence => true
validates :hidee_id, :presence => true
end
game.rb
has_many :reverse_hides, :foreign_key => "hidee_id",
:class_name => "Hide",
:dependent => :destroy
has_many :hiders, :through => :reverse_hides
paths.rb
resources :games do
member do
post :publish
post :unpublish
get :view
get :hidees, :hiders
end
我正在尝试做两件事: 1. 编写一个函数,允许我从提要中隐藏游戏,如果游戏和玩家退出之间的隐藏关系之间的关系,以及 2. 编写一个“显示隐藏”按钮,该按钮允许我返回玩家“隐藏”的所有项目。
到目前为止,第 1 部分。我在视图中有以下代码,虽然这在设置关系方面起到了作用,但它并没有从 feed 中“隐藏”游戏——我猜我需要 ajax为此??
- if current_profile.hidden?(game)
= form_for current_profile.hides.find_by_hidee_id(game), :html => { :method => :delete } do |f|
= f.submit "Unhide", :title => "Unhide this game."
- else
= form_for current_profile.hides.build(:hidee_id => game.id) do |f|
= f.hidden_field :hidee_id
= f.submit "Hide", :title => "Hide this game"
非常感谢您查看本文,我知道它很长,但我将不胜感激您提供的任何帮助。另外,感谢您抽出时间。
I have a ROR app that has many players, and many proposed games. The games display on a feed and a player can decide to hide them from this feed. The hidden function works like this:
in player.rb:
has_many :hides, :foreign_key=> "hider_id",
:dependent => :destroy
has_many :hidees, :through => :hides
def hidden?(hidee)
hides.find_by_hidee_id(hidee)
end
def hide!(hidee)
hides.create!(:hidee_id => hidee.id)
end
def unhide!(hidee)
hides.find_by_hidee_id(hidee).destroy
end
hides_controller.rb
class HidesController < ApplicationController
def create
@game = Game.find(params[:hide][:hidee_id])
current_profile.hide!(@game)
redirect_to :back
end
def destroy
@game = Hide.find(params[:id]).hidee
current_profile.unhide!(@game)
redirect_to :back
end
end
hide.rb
class Hide < ActiveRecord::Base
attr_accessible :hidee_id
belongs_to :hider, :class_name => "Player"
belongs_to :hidee, :class_name => "Game"
validates :hider_id, :presence => true
validates :hidee_id, :presence => true
end
game.rb
has_many :reverse_hides, :foreign_key => "hidee_id",
:class_name => "Hide",
:dependent => :destroy
has_many :hiders, :through => :reverse_hides
routes.rb
resources :games do
member do
post :publish
post :unpublish
get :view
get :hidees, :hiders
end
I'm trying to do two things: 1. Write a function that would allow me to hide a game from the feed if a relationship between hidden relationship between game and player exits, and 2. write a "show hidden" button that would allow me to return all projects that were "hidden" by the player.
So far with part 1. I have the following code in the view, and while this does the trick in terms of setting up the relationships, it does not "hide" the game from the feed--I'm guessing I would need ajax for that??
- if current_profile.hidden?(game)
= form_for current_profile.hides.find_by_hidee_id(game), :html => { :method => :delete } do |f|
= f.submit "Unhide", :title => "Unhide this game."
- else
= form_for current_profile.hides.build(:hidee_id => game.id) do |f|
= f.hidden_field :hidee_id
= f.submit "Hide", :title => "Hide this game"
Thank you so much for viewing this, I know it's quite long, but I would appreciate any help you could offer. Also, thank you for you time.
