In my rails application I have a page where there are several "proposals". I need a way where I can go in and select the "winning proposal". Then I want that proposal's div border color to change to green. The proposal also exists on three other pages so I would like to change its color in those places as well as the text in those divs. What's the best way to do this in rails?
在我的rails应用程序中，我有一个页面，其中有几个“提案”。我需要一种可以进入并选择“获胜提案”的方式。然后我希望该提案的div边框颜色变为绿色。该提案还存在于其他三个页面上，因此我想更改这些地方的颜色以及这些div中的文本。在rails中执行此操作的最佳方法是什么？

I would have a field in a Proposal model that is a boolean, and indicates if it is winning or not. Have it default to false. Thats :default => false in the migration.
我会在Proposal模型中有一个布尔值的字段，并指示它是否获胜。它默认为false。多数民众赞成：迁移中默认=> false。
Then in your view, if the proposal is winning, you could give your div a class like .winning-proposal which would correspond to a CSS class you would put in proposal.css.scss or whatever is in your stylesheets directory. You would not include this class in the div if the Proposal not winning.
然后在您看来，如果提案获胜，您可以为您的div提供类似.winning-proposal的类，该类对应于您将放在proposal.css.scss中的CSS类或者样式表目录中的任何类。如果提案没有获胜，您不会在div中包含此类。
To set the winning proposal, you simply need to update attributes of the Proposal instance and set the winning boolean column for the model to true.
要设置获胜提议，您只需更新Proposal实例的属性，并将模型的获胜布尔列设置为true。
Hope that makes sense!
