Magento 文档鼓励用 entity setup (Mage_Eav_Model_Entity_Setup) 的方式去定义实体。这个类很强大,但我觉得不够灵活,因为无法用它精确控制 attribute, attribute group 和 attribute set。
Attribute group 和 attribute set 是在两个维度分组 attribute,这样来组织 attribute 基本够用。但 setup 这个类添加 attribute 时,有不够周到的逻辑:
如果 $attr[‘user_defined’] == 1 && empty($attr[‘group’]),那么这个 attribute 不会被添加到任何 attribute group 和 attribute set。我觉得更好的逻辑是添加到 general attribute group。
如果 empty($attr[‘user_defined’]) && !empty($attr[‘group’]),那么 $attr[‘group’] 会被忽略,attribute 总是被添加到 general attribute group。
没办法,已经这样啦,提供 install entities array 时,就避免进入这两种逻辑吧。
如果我来重写 setup 类里的 addAttribute 方法,我会:
Today, I went into Churchill Square shopping centre. To my surprise, most shops are open on the New Years Day.
I bought a white HTC Wildfire with an O2 SIM from Phones4u, as a gift for my mother. Phones4u is doing a promotion on 4 or 5 mobiles, and Wildfire is one of them. It is priced at £129.95 with £10 airtime purchase. It claims to be half price, but actually, I find the second cheapest supplier is Tesco, price is £159.97 without airtime purchase.
Anyway, Phones4u is the cheapest. So I go for it. Then a second surprise – I find the handset is not locked to O2 network. I google for a while, and find it is not just my luck. Pay As You Go handset purchased from independent retailer is usually unlocked.
This saves me about £10 to buy SIM unlock code.
I feel very happy for trying to insert an Orange SIM before paying for unlock code.
Magento 1.5.0.0 目前还是 alpha2 版,因为安装到第二步就有一个很明显的 bug,本来想等等再用的。
可是 1.4.2.0 正式版 dataflow profile 跑不起来,一点 “Run Profile in Popup”,出来的 popup 就是空白。我很喜欢用外部编辑器格式化好数据,然后用 dataflow import 到 Magento 数据库。我有很多 modules 也用到 dataflow 来完成初始化,如果 dataflow 跑不起来,会给我造成很大的麻烦。
联想到 Magento 1.5.0.0 在 release note 里说到它对 dataflow 作了改进,我想很可能修正了 1.4.2.0 带来的 bug。两害取其轻,所以我跳过 Magento 1.5.0.0 的全新安装过程,用 1.4.2.0 的数据库让 Magento 1.5.0.0 跑了起来。果然如我所料,dataflow profile 在 1.5.0.0 下工作正常。
