Rails 6和neo4j.rb？
Rails 6和neo4j.rb？
提问于 2019-04-28 08:40:39
在Neo4j.rb中是否有针对Rails 6的开发？在一个新的rails 6(rc1)项目中，如果我创建了几个脚手架，然后运行‘rakene4j:migrate:all’，我会得到一个错误，当我快速跟踪它时，ActiveModel的内部洞穴比我可以解析的更深：

它是用这个pull request修复的。使用neo4jrb版本9.6.0和更高版本。

看起来它与登陆RC1的this PR有关，我也遇到了同样的问题。我pinged了那个帖子，看看是不是故意的。在此期间，尝试回滚到上一个测试版或猴子修补ActiveModel::NullMutationTracker (这就是我所做的，并确认它解决了这个问题)，通过添加以下方法：
def forget_change(attr_name)
end
def original_value(attr_name)
end
def force_change(attr_name)
