根据动作ID渲染Rails局部 [英] Render a rails partial based on the id of an action

问题描述

我正在建立一个小型电子商务网站，出售各种男女服装.我想根据用户所在的分类法来呈现部分内容.例如，如果用户位于mysite.com/t/women/pant，我想呈现_women.html.erb，或者，如果用户位于在mysite.com/t/men/shirts中，我想渲染_men.html.erb.

I'm building a small ecommerce site that sells a variety of mens and womens clothing. i would like to render a partial based on which taxonomy the user is in. For example, if the user is at mysite.com/t/women/pants I would like to render _women.html.erb, or, if the user is at mysite.com/t/men/shirts I would like to render _men.html.erb.

我有一个分类法模型，该模型有很多类，而分类法模型有很多产品.

I have a Taxonomy model that has_many taxons, and the Taxon model has_many products.

在taxons_controller.rb中，我有:

In taxons_controller.rb I have:

def show
  @taxon = Taxon.find_by_permalink(params[:id])
  return unless @taxon
  @taxonomy = Spree::Taxonomy.all
  @taxon_title = Spree::Taxon.all 

  @searcher = Spree::Config.searcher_class.new(params.merge(:taxon => @taxon.id))
  @searcher.current_user = try_spree_current_user
  @searcher.current_currency = current_currency
  @products = @searcher.retrieve_products

  respond_with(@taxon)
end

在分类群中#show我有:(我知道这是错误的)

And in taxons#show I have: (which I know is wrong)

    <% @taxon_title.each do |title| %>
  <% @taxonomy.each do |taxonomy| %>
  <% if title.name == taxonomy.name %>
    <%= render "spree/shared/#{title.name.downcase}" %>
  <% end %>
  <% end %>
  <% end %>

当我访问mysite.com/t/women/long-sleeve时，rails调试器将显示:

When I go to mysite.com/t/women/long-sleeve the rails debugger displays :

controller: spree/taxons
action: show
id: women/long-sleeve

我如何访问内部操作的id，以便在控制器/视图中可以执行以下操作:

How do I access the id of the action im inside, so that in the controller/view I can do something like:

'如果id等于'women'，则渲染狂欢/共享/#{title.name.downcase}"'

'if id equals 'women' render "spree/shared/#{title.name.downcase}"'

分类名称在哪里?

我想我需要在控制器的show动作中找到(params [:something]，但是我对params不太清楚.

I imagine I need to find(params[:something] in the show action of the controller, but I'm a little unclear about params.

* * * @ beck03076这是一个很棒的把戏.非常感谢你.但它仍然无法正常工作.

* * * @beck03076 That's a great trick. Thank you very much. But it's still not working.

在我的控制器中，我输入:

In my controller I put:

@taxon_id = Spree :: Taxon.find(params [:id])

@taxon_id = Spree::Taxon.find(params[:id])

然后在我执行的操作中:

Then in the action I put:

如果@taxon_id == params [:id]，则渲染狂欢/共享/妇女"

render 'spree/shared/women' if @taxon_id == params[:id]

当我加载页面时，它说您要查找的页面不存在".我的部分在正确的目录中.我的语法正确吗?

And when I load the page it says 'the page you were looking for doesn't exist'. My partial is in the correct directory. Is my syntax correct?

我的参数是:

{控制器" =>狂欢/类群"，动作" =>显示"，"id" =>妇女/长袖"}

{"controller"=>"spree/taxons", "action"=>"show", "id"=>"women/long-sleeve"}

再次感谢您的帮助！

推荐答案

每当您不清楚参数时，只需将以下行放在操作中并执行操作即可.

Whenever you are unclear about params, just put the lines below in the action and execute the action.

p "****************************"
p params
p "****************************"

现在，转到启动服务器的终端.

Now, goto the terminal in which you started your server.

找到这两个" * ** * ** * "，它们之间的所有内容参数.

Locate those two "*******" and everything thats in between them are params.

params基本上是红宝石哈希.

params is basically a ruby hash.

示例:

参数看起来像这样，{:controller =>"hello"，:action =>"bye"，:id => 7，:others =>"OK"}

params look like this, {:controller => "hello",:action => "bye", :id => 7, :others => "OK"}

在您的控制器中访问ID，请使用params [:id].(= 7)

In your controller to access the id, use params[:id].(=7)

要访问其他人，请使用params [:others].(="OK")

to access others, use params[:others].(="OK")
