如何从某种角度看待控制器的方法?
原标题:How to call a controller s method from a view?

I m 在Ruby-On-Rails开发小型应用。 我想从某种角度看待控制器的方法。 这种方法只能使用数据库表格中的一些插入。 这样做的正确方式是什么? 我曾尝试过类似情况,但显然没有执行该方法:

<%= link_to  Join , method: join_event %>
最佳回答

联系方式中的方法选择实际上是“吉大港山区”的方法,而不是行动的名称。 在通过《吉大港山区行动计划》删除方案时,这非常有益,因为《危险航程》利用DELETE方法打击销毁行动。

你们需要做的是,为你们的行动开辟了一条道路。 假定其名称为join_event,在您的路线上添加以下内容。 rb:

match  /join_event  =>  controllername#join_event , :as =>  join_event 

确保把控制人姓名改为你使用的控制人名称。 接着,对你的看法作了如下更新:

<%= link_to  Join , join_event_path %>

——胎面法是根据路面文件的价值产生的。

为了组织你的守则,你可能希望把这些插入纳入固定模式方法。 因此,如果你有一个称为<代码>MyModel的模型,则你可以这样做。

class MyModel
  # ...
  def self.insert_examples
    MyModel.create(:name => "test")
    MyModel.create(:name => "test2")
    MyModel.create(:name => "test3")
  end
end

Then just execute it in your action via:

MyModel.insert_examples
