使用Ruby中的按钮更改属性的值

Question

我如何在我的Ruby应用程序中添加一个按钮,让我在一个页面内更改属性的值,即item.paid的值,从false变为true.

问题:我想从不同的模型/视图中做到这一点.例如,在Customers模型中,将属于该客户的所有"项目"的值更改为已付款(单击表单按钮).

Answer 1

app/controllers/customers_controller.rb

class CustomersController < ApplicationController

  def mark_all_items_paid
    customer = Customer.find(params[:id])
    customer.items.find_each { |item| item.update_column(:paid, true) }
    # redirect, respond with json, whatever
  end

end

config/routes.rb

resource :customers do
  member do
    post :mark_all_items_paid
  end
end

你的观点:

<%= form_tag { controller: 'customers', action: 'mark_all_items_paid', id: @customer }, { method: :post } do -%>
  <%= submit_tag "Mark All Items Paid" %>
<% end -%>
