自定义收集路线的polymorphic_path [英] polymorphic_path for custom collection route

问题描述

我具有以下路线定义:

resources :documents do
  collection do
    post :filter
  end
end

以及以下模型结构:

class Document < ActiveRecord::Base
  belongs_to :documentable, :polymorphic => true
end

class User < ActiveRecord::Base
  has_many :documents, :as => :documentable
end

和控制器结构:

class DocumentsController < ApplicationController
  def index
    # not important
  end

  def filter
    # not important
  end
end

我可以很容易地说:

polymorphic_path([@user, Document])

获取路径/users/1/documents ，但是我想说:

to get the path /users/1/documents, but I want to be able to say:

filter_polymorphic_path([@user, Document])

要获取路径/users/1/documents/filter ，很遗憾，这不起作用.

to get the path /users/1/documents/filter, unfortunately, this doesn't work.

对于每个 documentable 模型，每个人都知道如何在不添加以下内容的情况下实现这一目标:

Anyone know how I can pull this off without adding the following to my routes, for each of my documentable models:

resources :users do
  resources :documents do
    collection do
      post :filter
    end
  end
end

推荐答案

polymorphic_path([@user, Document], :action => 'filter')给您/users/:user_id/documents/filter.

此外，polymorphic_path([@user, Document], :action => 'filter', :sort_order => 'this-order')给您/users/:user_id/documents/filter?sort_order=this-order.

我遇到了同样的问题，认为您可以将edit_polymorphic_path中的edit替换为所需的任何方法.

I ran into the same problem thinking you can replace the edit in edit_polymorphic_path to whatever method you want.
