Ruby on Rails 5中simple_form如何实现客户端长尾词验证？

本文共计175个文字，预计阅读时间需要1分钟。

当我在gemfile中加入以下内容时：gem 'simple_form'gem 'client_side_validations'

当我把以下内容放在我的gemfile中时：

gem 'simple_form' gem 'client_side_validations'#, github: 'DavyJonesLocker/client_side_validations' gem 'client_side_validations-simple_form'#, github: 'DavyJonesLocker/client_side_validations-simple_form'

结果如下：

Bundler could not find compatible versions for gem "rails": In Gemfile: rails (= 5.0.0) client_side_validations-simple_form was resolved to 3.2.0, which depends on client_side_validations (~> 4.2.0) was resolved to 4.2.0, which depends on rails (< 4.3.0, >= 4.0.0)

让这些宝石发挥作用的任何想法？

您可以通过指定分支来使用带有Rails 5的client_side_validations：

gem 'client_side_validations', github: 'DavyJonesLocker/client_side_validations', branch: 'rails5'

如果使用简单形式：

gem 'client_side_validations-simple_form', github: 'DavyJonesLocker/client_side_validations-simple_form', branch: 'rails5'
