引导程序:主题错误常量 NameError ->const_定义? [英] bootstrap:themed wrong constant NameError -> const_defined?

问题描述

尝试使用 Rails 3.2.2 运行以下程序，切换到 3.2.1 并尝试另一台机器，看看它是否与核心/操作系统相关.

Trying to run the following using Rails 3.2.2, switched to 3.2.1 and tried another machine to see if it was more core / OS related.

我尝试:

rails g bootstrap:themed events

我明白了:

.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:229:in `const_defined?': wrong constant name event (NameError)
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:229:in `block in constantize'
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:228:in `each'
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:228:in `constantize'
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/core_ext/string/inflections.rb:54:in `constantize'
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/twitter-bootstrap-rails-2.0.4/lib/generators/bootstrap/themed/themed_generator.rb:58:in `columns'
    from (erb):6:in `template'

推荐答案

不需要降级 gem 版本.相反，只需更改:

No need to downgrade the gem version. Instead, just change:

rails g bootstrap:themed events

到:

rails g bootstrap:themed Events

您需要将模型名称大写和复数，这很愚蠢，但它有效

You need to capitalize and pluralize the model name, which is dumb, but it works
