我正在使用destroy
在我看来，我有：
#delete_archive_modal.modal.fade
.modal-header
%h3
%i.icon-exclamation-sign
Attention
.modal-body
%p= "Are you sure you want to delete this portal?"
.modal-footer
%a.btn{"data-dismiss" => "modal", :href => "#"} Cancel
= link_to 'Delete', delete_portal_path(portal)
路线：
resources :portals do
resources :pill_tabs, only: [:show, :edit]
resources :page_urls do
collection do
get :redirects
end
end
resources :zero_touch_configs do
member do
get :history
end
end
member do
get :navigation
get :history
get :sitemap
get :url_list
post :generate_sitemap
post :add_modules
post :archive
post :delete
end
collection do
get :index, path: '/'
get :new, path: '/new(/:portal_type)'
get :accessible_sites
get :archive_index
get :delete
end
在我的控制器中：
def destroy
@portal = Portal.find(params[:id])
@portal.destroy
flash[:notice] = 'Portal deleted successfully.'
redirect_to action: :archive_index
end
路线：
portals GET /portals(.:format) portals#index

portal_config_bundle GET /portals/:portal_id/config_bundles/:id(.:format)
但我收到路由错误，不知道从哪里开始......
No route matches [GET] "/portals/asdg/delete"
任何人都可以分享指南或指向我帮助我了解这里有什么问题的文档吗？

尝试
= link_to 'Delete', portal_path(portal), method: :delete
以下是portal
portals GET /portals(.:format) portals#index
POST /portals(.:format) portals#create
new_portal GET /portals/new(.:format) portals#new
edit_portal GET /portals/:id/edit(.:format) portals#edit
portal GET /portals/:id(.:format) portals#show
PATCH /portals/:id(.:format) portals#update
PUT /portals/:id(.:format) portals#update
DELETE /portals/:id(.:format) portals#destroy
在您的路线中，由于
，您将拥有delete_portal路径
member do
post :delete
end
如果您想调用此方法，那么您已在控制器中为此操作定义方法，并使用method: :post
但是在RESTful路由中，删除操作总是DELETE方法，请参阅上面的路由。

link_to代码中存在两个问题。
您使用了delete_portal_path(portal)，但如果您在控制台上运行rake routes，则会看到没有此类路由存在。它有portal_path(portal)。
如果显示（GET默认值），更新（PUT）和删除（DELETE），则需要在路径中指定方法类型。因为所有人共享相同的路径portal_path(portal)。
所以你的最终路线应该是：
= link_to 'Delete', portal_path(portal), method: :delete

使用delete
时需要定义http方法 = link_to 'Delete', portal_path(portal), method: :delete
它会起作用。
