Question

我一直在尝试从以下链接配置插件 - https://www.redmine.org/plugins/digest

当我尝试发送测试邮件时，我收到以下错误。未定义的方法`长度＆＃39;为true：TrueClass

这是日志文件中的错误

Looking up projects to process...
Couldn't find all EnabledModules with 'id': (all, {:conditions=>["name = 'redmine_digest'"]}) (found 0 results, but was looking for 2)

检查@test.nil?是不够的;你还需要检查它的类型。您可以通过调用String上的to_s方法将其转换为@test对象，或者您可以检查其类，它是字符串还是不符合以下内容：

if !@test.nil? && @test.is_a? String
  # do your stuff
else

end
