Rails 4 client side validation
提问by tblakey89
Since upgrading my site to Rails 4, the client-side-validations gem has stopped working for me. I have had a look at the various alternatives such as jquery-validation-rails and judge, which involve writing quite a bit of javascript, especially for a site so large. And in the case of jquery-validation-rails, re-doing all the validation rules client side. Considering Rails is such a popular framework, it surprises me that there is no 'easy' option. Is there any gem which anyone else is aware of, which does validation as well as the client-side-validation gem?
自从将我的网站升级到 Rails 4 后，客户端验证 gem 已停止对我来说有效。我查看了各种替代方案，例如 jquery-validation-rails 和 Judge，它们涉及编写相当多的 javascript，尤其是对于如此大的站点。在 jquery-validation-rails 的情况下，重新执行客户端的所有验证规则。考虑到 Rails 是一个如此流行的框架，让我感到惊讶的是没有“简单”的选择。是否有其他人知道的任何 gem，它进行验证以及客户端验证 gem？
Or is the best alternative to use the ModelName.validators method mixed with some ajax, and do the validation through the jquery-validation-rails gem?
或者是将 ModelName.validators 方法与一些 ajax 混合使用并通过 jquery-validation-rails gem 进行验证的最佳替代方法？

Also this guy seemed to have gotten the same gem you are using to work by using the 4-0-beta branch.
此外，这个家伙似乎已经通过使用 4-0-beta 分支获得了您用来工作的相同 gem。
Client Side Validations and Rails4
If the 4-0-beta branch works for you, consider helping to maintain the gem to keep it alive.
如果 4-0-beta 分支适合您，请考虑帮助维护 gem 以使其保持活力。
To use a certain git repo version in your Gemfile:
要在您的 Gemfile 中使用某个 git repo 版本：
gem 'client-side-validations', :git => 'https://github.com/bcardarella/client_side_validations/tree/4-0-beta'

While the client side validations will work for the simple cases, they'll require an enormous amount of workarounds to work with more complicated scenarios (for instance - conditional validations). I would recommend using Judgeinstead, which give you more control.
虽然客户端验证适用于简单的情况，但它们需要大量的解决方法来处理更复杂的场景（例如 - 条件验证）。我建议改用Judge，这会给你更多的控制。

I was able to use a fork of the original client_side_vlaidations that is very active at the moment. I am using the latest version of simple_form, rails 4.1.8, and this client_side_validations. Simple setup with basic config.
我能够使用目前非常活跃的原始 client_side_vlaidations 的一个分支。我正在使用最新版本的 simple_form、rails 4.1.8 和这个client_side_validations。使用基本配置进行简单设置。

I know the question is old, but how about good old require: "require"?
我知道这个问题很老了，但是老式的 require: "require" 怎么样？
For example in view:
例如在视图中：
<%= f.text_area :body, placeholder: "Write your review here...", class: "form-control", rows: "5", required: "required" %>

If you are using Bootstrap Form for Rails, you can give bootstrap_validator_rails a try.
如果你正在使用 Bootstrap Form for Rails，你可以试试 bootstrap_validator_rails。
