如何美化 Rails 中的验证 [英] how to beautify validations in rails

问题描述

我有一个简单的脚手架 rails 应用程序，它正在执行validataes_presence_of.

I have a simple scaffold rails application that is doing validataes_presence_of.

验证使每个文本字段都有边框.我只希望错误消息显示在顶部.

The validation is making each textfield bordered. I just want the error messages to be displayed on top.

如何对验证进行这些类型的更改或颜色更改

How can I make these type of changes or color changes to the validation

推荐答案

Rails 应用程序存储它们的 CSS 在 [application_root]/public/stylesheets 中.一个新的 rails 应用程序将在此目录中有一个名为 default.css 的文件.该文件包含以下内容:

Rails applications store their CSS in [application_root]/public/stylesheets. A new rails app will have a file called default.css in this directory. This file contains the following:

#errorExplanation {
  width: 400px;
  border: 2px solid red;
  padding: 7px;
  padding-bottom: 12px;
  margin-bottom: 20px;
  background-color: #f0f0f0;
}

#errorExplanation h2 {
  text-align: left;
  font-weight: bold;
  padding: 5px 5px 5px 15px;
  font-size: 12px;
  margin: -7px;
  background-color: #c00;
  color: #fff;
}

#errorExplanation p {
  color: #333;
  margin-bottom: 0;
  padding: 5px;
}

#errorExplanation ul li {
  font-size: 12px;
  list-style: square;
}

如果您在这里尝试使用一些参数的值 - 特别是 border - 您可能会发现一些看起来更合您口味的东西.

If you play about with the values of some of the parameters here - in particular border - you might find something that looks more to your taste.
