瞎扯淡 什么是 “大型” Rails 项目

a0nqm · 2017年03月06日 · 最后由 griffinqiu 回复于 2017年09月21日 · 2414 次阅读

有听到前辈讲过一些”“大型”Rails项目的管理方法,比如抽Service、拆Gem等。 我认为项目“大小”的定义很模糊。所以多少行的项目算得上是“大型”呢?

比如我公司里的这个项目,代码统计如下:

+----------------------+-------+-------+---------+---------+-----+-------+

+----------------------+-------+-------+---------+---------+-----+-------+
  Code LOC: 9568     Test LOC: 567     Code to Test Ratio: 1:0.1

这种规模算是小型还是大型呢?

我们项目拆的七零八落的, 这是其中一个

User.count >= 10_000_000

吧?

知人的,其实 KnewOne 项目全部代码量比这个还多... 没存代码就是

495 个 Model ...

我表示从没做过超过 50 个 Model 的项目

看了一下,有超过 50 个 Model 的,但应该在 100 以内

这个数据使用什么工具统计的?

huacnlee 回复

KO 也肯定超过50了... 知人这边是因为企业系统,模型围绕业务做的,业务多了模型数量就上去了... 不过可能那统计有水分,不少都是虚拟模型应该

接近600个Model,看来我做的是大型Rails项目😂

rake stats
jasl 回复

感觉各类业务多了,应该拆成小项目来搞,这样单独看各类业务的时候不会觉得东西好多。

想想那么多 Model,那么多业务函数,跑个 CI 得要多久啊

说起CI时间的话,想起4年前的一个rails项目,CI上跑一次完整回归大概5个多小时

好荣幸4年前跟大神一起做个这个大项目。

jasl 回复

GitLab 算不算大项目?

Model 136,许多还应该是抽象实现,表数量:63 张

不过跑 CI 也要两三个小时以上,这东西搞了 UI 测试哪套,改动起来特别费神。


Discourse - 175 Models

那俩实际比模型数复杂的多吧... 最近刚好在看

jasl 回复

看过Discourse,比预想的要复杂得多。

a0nqm 回复

Gitlab 更工整一些,Discourse 那个太乱了。。

huacnlee 回复

肯定算大型项目了 Gitlab 还拆了好多到子项目里去,包括 Redmine 模型的代码都不多的,模型只能算核心数据结构吧,这几个项目的 lib 目录都是大头...

rainchen 回复

你们CI用的是什么工具?

我也觉得gitlab叫大型项目有点反直觉,毕竟没有人管git或者gerrit叫大型软件…

nouse 回复

但其实Gitlab不算小。 不过真要说大型项目,Github绝对算一个。
