你好。我正在尝试volunteers通过将user_idof附加current_user到数组来更新模型中的数组。但是，当我测试它并单击链接到update操作的“接受任务”时，没有任何反应。我该如何解决？
update由于未指定使用“ PUT”方法，因此“接受任务”链接将不会链接到操作。相反，它将链接到“显示”操作。
而且，您正在传递current_user.profile给tasks_path助手-这不会为您提供正确的RESTful地址。更改链接，使其看起来像这样：
<%= link_to "Accept Task", task_path(@task), :method => :put %>
甚至更简单：
<%= link_to "Accept Task", @task, :method => :put %>
