AJAX删除rails ...错误：未定义的局部变量或方法删除

Question

尝试删除AJAX请求时出错。

我认为它来自视图中的html生成器函数。

NameError in ProductsController#edit


undefined local variable or method `delete' for #<#<Class:0x000001071a0998>:0x00000108bb7bb0>

视图

  <% @product.pictures.each do |p| %>
    <%= image_tag p.image.url(:medium) %>
    <%= link_to "Delete" , p, remote: true, method: delete %>
  <% end %>

路线

resources :pictures, only: [:destroy]

的CoffeeScript

$ ->
  $("a[data-remote]").on "ajax:success", (e, data, status, xhr) ->
      alert "The post was deleted."

图片控制器

  def delete
    @picture = Picture.new(params[:user])
    @picture.destroy
  end

Answer 1

应该是method: :delete。 delete不是您可以调用的方法。
