Ruby on Rails：删除重定向到显示页面的链接

Question

I'm working on a rails 5.0 application. It's a legacy application and has been poorly maintained over the years and god knows what hasn't been updated on it properly (for example, its still using a public/ structure to contain all of its stylesheet and javascript files).

I'm having trouble getting the default rails delete routes to execute.

Consider the following controller action:

class Admin::PackagesController < ApplicationController

  def destroy
    @package = Package.find(params[:id])
    @package.destroy

    respond_to do |format|
      format.html { redirect_to root_url}
      format.xml  { head :ok }
    end
  end

But when I call the following link:

<%= link_to 'Destroy', ['admin', package], :confirm => 'Are you sure?', :method => :delete %>

It doesn't call the destroy action: it goes to the show action for the individual package.

I'm not sure if this is still an issue but I ran into it with a Rails 7 blog/comments app. The following code within a 'comment' partial (for Post show page) and a comment controller fix solved the issue for me.

_comment.html.erb:

    <%= link_to 'Delete', [comment.post, comment], data: { turbo_method: :delete, turbo_confirm: 'are you sure?' }, class: 'button is-danger' %>

comments_controller.rb:

def destroy
    @post = Post.find(params[:post_id])
    @comment = @post.comments.find(params[:id])
    @comment.destroy
    redirect_to post_path(@post), status: :see_other
  end

The status: :see_other section of the redirect was essential in it working and understanding how Rails handles redirects and this link helped a lot!

<%= link_to 'Destroy', package_path(package), method: :delete %>
