railsにていいね機能実装中　ActionController::UrlGenerationError in Books#show　エラー

railsでいいね機能を実装しているところなのですが、
ActionController::UrlGenerationError in Books#show
Showing /home/vagrant/work/vagrant/bookers2/app/views/books/show.html.erb where line #28 raised:

No route matches {:action=>"destroy", :book_id=>nil, :controller=>"favorites"}, missing required keys: [:book_id]
のエラーが出て進めなくなってしまいました。
indexの方と同じコードをshowに貼り付けたのですが、indexはエラーが出ないのですが、showの方がでます

show
1<td>
2							<% if @book.favorited_by?(current_user) %>
3							<li>
4							   <%= link_to book_favorites_path(book), method: :delete do %> ←　エラー
5							    <i class="fa fa-heart" aria-hidden="true" style="color: red;"></i>
6							    <%= @book.favorites.count %> いいね
7							  <% end %>
8							</li>
9							<% else %>
10							<li>
11							 <%= link_to book_favorites_path(book), method: :post do %>　←　エラー
12							    <i class="fa fa-heart-o" aria-hidden="true" style="color: red;"></i>
13							    <%= @book.favorites.count %>
14							  <% end %>
15							</li>
16							<% end %>
