Railsのdestroyがうまくいきません。

Question

railsのdestroyがうまくいきません。
削除ボタンでpostに紐づいているコメントを削除させようを思っているのですが、

No route matches {:action=>"show", :controller=>"comments", :id=>nil, :post_id=>"3"}, missing required keys: [:id]

というエラーメッセージが出てきます。
どうやらコメントのidが渡って来ないようで、ルーティングがうまくいってないようです。

どうすればidが渡ってくるようになるでしょうか？

HTMLとrouteとcontrollerは以下の通りです。

show.html.erb↓

<% @post.comments.each do |comment| %>
        <div class="comment">
        <%= comment.body %>
        <%= link_to '削除',
        post_comment_path(@post, comment),　#ここが間違ってる？
        method: :delete,
        class: 'x-btn',
        data: { confirm: 'Sure?' } %>
        </div>
        <% end %>

comments_controller.rb↓

def destroy
        @post = Post.find(params[:post_id])
        @comment = @post.comments.find(params[:id])
        @comment.destroy
        redirect_to("/posts/#{@post.id}")
    end

route↓

Answer 1

show.html.erb↓

<% @post.comments.each do |comment| %>
        <div class="comment">
        <%= comment.body %>
        <%= link_to '削除',
        "/posts/#{@post.id}/comments/#{comment.id}",
        method: :delete,
        class: 'x-btn',
        data: { confirm: 'Sure?' } %>
        </div>
        <% end %>

post_comment_path(@post, comment)
↓
"/posts/#{@post.id}/comments/#{comment.id}"

としたことで解決できました。
