ruby-on-rails-4 - How set up and call a rails method in the view to update an attribute of an object

Question

I need some help in figuring out how to set up a helper method and then call in in the view. What i need to do is update a single attribute of a model object.

How I plan to do this is to call a helper method Bid, which will update the attribute by the same increment every time, for example, by one dollar.

Then, I need a way to call this helper method in the view and update the auction attribute current_price and display it in the view. Any ideas on how this could be done? Thanks

只需更新控制器中的价格并将Bid实例传递给视图。在视图中，您调用如下内容：

@bid.price

访问当前出价的价格。
