Pavel Rodionov 14 年之前 The explained aproach lacks one thing - schema incremental update. If you add/drop some column, you need to drop whole table, or create DML migration scripts for expando tables (which is entertaining task for one entity, but if you have a lot of entities it could take whole day, if not more) 请登录以投票。 以……回复 取消 Ray Augé Pavel Rodionov 14 年之前 Why? A simple ExpandoColumnLocalServiceUtil.deleteColumn(ong companyId, long classNameId, String tableName, String columnName);will remove the column from the table as well as all values associated with it! 请登录以投票。 以……回复 取消 Pavel Rodionov Ray Augé 14 年之前 Hm, so your approach is to pollute code with such statements? So for every added/removed column some precondition should exist? What if I add 50 columns in a row. Also I don't understand how it will work if I want to change type of column, for example from ExpandoColumnConstants.STRING to ExpandoColumnConstants.DATE. 请登录以投票。 以……回复 取消 Juan Fernández Pavel Rodionov 14 年之前 Hi Pavel:1.- The idea is to avoid doing this by hand in every installation of the product. If you have a plugin you can deploy it in the server and it'll do all that tasks.2.- The number of columns is not important: just add it in the hook code.3.- You can use the type you need for your field using ExpandoColumnConstants and it shouldn't be a problemRegardsJuan 请登录以投票。 以……回复 取消
