Question

Rails 4.21
Ruby 2.5

我有一个使用标准MVC结构的组织模型。

show动作，显示组织的视图（姓名，联系信息等）。

我添加了一个OrganizationNote MVC结构。

我想做的是，在组织展示视图中，添加一个＆＃34;添加注释＆＃34;按钮，类似于：

link_to 'Add Note', new_organization_note_path, :class => "btn btn-primary btn-lg"

但我需要将组织ID传递给New OrganizationNote。现在，当我尝试时，没有参数与调用一起传递：

link_to 'Add Note', new_organization_note_path(@organization.id), :class => "btn btn-primary btn-lg"

我没有看到任何参数传递。

我如何实现这一目标，是否需要创建任何特殊路线？

我在routes.rb中添加了以下内容：

resources :organizations do
  resources :organization_notes
end

产生了以下路线：

organization_organization_notes GET /organizations/:organization_id/organization_notes(.:format) organization_notes#index
POST /organizations/:organization_id/organization_notes(.:format) organization_notes#create
new_organization_organization_note GET /organizations/:organization_id/organization_notes/new(.:format) organization_notes#new
edit_organization_organization_note GET /organizations/:organization_id/organization_notes/:id/edit(.:format) organization_notes#edit
organization_organization_note GET /organizations/:organization_id/organization_notes/:id(.:format) organization_notes#show
PATCH /organizations/:organization_id/organization_notes/:id(.:format) organization_notes#update
PUT /organizations/:organization_id/organization_notes/:id(.:format) organization_notes#update
DELETE /organizations/:organization_id/organization_notes/:id(.:format) organization_notes#destroy

我将链接修改为：

link_to 'Add Note', new_organization_organization_note_path(:organization_id => @organization.id), class: 'btn btn-primary btn-lg'

在organization_notes_controller.rb中，我有：

def new
  @organization_note = OrganizationNote.new
  @organization = Organization.find(params[:organization_id])
end

当我点击Add Note，按钮时，我收到以下消息：

Incomplete response received from application

从日志文件中：

Answer 1

要使OrganizationNote使用相对于Organization的网址，您需要使用nested resources。这将允许您指定要将Note应用于哪个组织的参数，例如

resources :organizations do
    resources :organization_notes
end

您可以使用rails routes确认路径现在包含参数。

（如果你只想要这个相对路线来创建Notes，你也可以只使用一个自定义路由而不是resources函数。）

Answer 2

您可以尝试以下解决方案。

# routes.rb
resources :organizations do
  resources :organization_notes
end

# new method
def new
  @organization = Organization.find(params[:organization_id])
  @organization_note = @organization.organization_notes.build
end

# views
link_to 'Add Note', new_organization_organization_note_path(:organization_id => @organization.id), class: 'btn btn-primary btn-lg'

将参数传递给新的控制器操作
