Maybe you are having a validation error. Update the delete method to use the bang after the destroy so it shows output. That should at least help you debug your current situation. Otherwise provide more details and I can update answer.
也许您遇到了验证错误。更新 delete 方法以在销毁后使用 bang 以显示输出。这至少应该可以帮助您调试当前的情况。否则提供更多详细信息，我可以更新答案。
def destroy
@patient = Patient.find(params[:id])
@patient.destroy!
redirect_to '/patients/new', :notice => "Your patient has been deleted"
end

You need in your view... there are different ways to pass the variable
你需要在你看来......有不同的方法来传递变量
<%= link_to "Delete", destroy_patient_path, :confirm => "Are you sure?", :method => :delete %>
Then in your routes.rb
然后在你的 routes.rb
#more member routes probably need definition but not showing them here
resources :patients do
member do
get :show
post :show
delete :destroy
end
end
The problem is you have not defined the route and you are not providing the path to call
问题是你没有定义路由，也没有提供调用路径

在
<%= link_to "Delete", :confirm => "Are you sure?", :method => :delete %>
<%= link_to "Delete", :confirm => "Are you sure?", :method => :delete %>
you are missing the pathpart
你错过了这个path部分
<%= link_to "Delete", destroy_patient_path, :confirm => "Are you sure?", :method => :delete %>
<%= link_to "Delete", destroy_patient_path, :confirm => "Are you sure?", :method => :delete %>
回答by cortex
You need to add the object you want to delete:
您需要添加要删除的对象：
<%= link_to "Delete", @patient, :confirm => "Are you sure?", :method => :delete %>
