Question

我在rails表单上遇到问题-它在编辑表单中添加了另一个id参数。我已经尝试添加带有对象ID的隐藏标签。

这是编辑表单

ActiveRecord::RecordNotFound (Couldn't find Product with 'id'=index):

我的编辑表单在索引页面上（我要从索引页面编辑产品）

form_for 辅助程序的构建方式如下：form_for(record, options = {}, &block)
您需要先指定记录，然后才能将url作为选项传递。

如果您将路由定义为CRUD，则edit_product_path是GET请求，因此不应将其用于更新操作。

因此，您可以像这样修改表单：

<% @products.each do |product| %>
  <% @categories = Category.all %> #btw, you can define this instance variable inside your controller products#index
  <%= form_for product, url: product_path(product), remote: true do |f| %>

    #the form

  <%= f.submit "Edit", class: "btn btn-light" %>
  <% end %>
<% end %>

您不再需要这种隐藏字段。

Ruby on Rails正在更改形式的id参数
