自定义收集路径的polymorphic_path
我有以下路由定义：
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
我可以轻松地在视图中说：
polymorphic_path([@user, Document])
获取路径 /users/1/documents，但我希望能够说：
filter_polymorphic_path([@user, Document])
要获取路径/users/1/documents/filter，不幸的是，这不起作用。
任何人都知道我如何能够在不将以下内容添加到我的路线中的情况下完成这个任务，对于我的每个可记录模型：
resources :users do
resources :documents do
collection do
post :filter
end
end
end
I have the following route definition:
resources :documents do
collection do
post :filter
end
end
and the following model structure:
class Document < ActiveRecord::Base
belongs_to :documentable, :polymorphic => true
end
class User < ActiveRecord::Base
has_many :documents, :as => :documentable
end
and controller structure:
class DocumentsController < ApplicationController
def index
# not important
end
def filter
# not important
end
end
I can easily in a view say:
polymorphic_path([@user, Document])
to get the path /users/1/documents, but I want to be able to say:
filter_polymorphic_path([@user, Document])
to get the path /users/1/documents/filter, unfortunately, this doesn't work.
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

polymorphic_path([@user, Document], :action => 'filter')为您提供/users/:user_id/documents/filter。另外，
polymorphic_path([@user, Document], :action => 'filter', :sort_order => 'this-order')为您提供/users/:user_id/documents /filter?sort_order=这个顺序。我遇到了同样的问题，认为您可以将
edit_polymorphic_path中的edit替换为您想要的任何方法。请参阅：http://api.rubyonrails.org/classes/ActionDispatch/Routing/PolymorphicRoutes.html
polymorphic_path([@user, Document], :action => 'filter')gives you/users/:user_id/documents/filter.Also,
polymorphic_path([@user, Document], :action => 'filter', :sort_order => 'this-order')gives you/users/:user_id/documents/filter?sort_order=this-order.I ran into the same problem thinking you can replace the
editinedit_polymorphic_pathto whatever method you want.See: http://api.rubyonrails.org/classes/ActionDispatch/Routing/PolymorphicRoutes.html
这样就可以了，而且读起来也不错。
或者这些
并且带有查询参数
并且，在视图中您也可以这样做：
This would do it, and it reads nicely.
Or these
And with a query param
And, in a view you can also do this:
