使用--template添加更新全部字段的模板,--feature sql/modifier打开自定义SQL修饰符,--feature sql/upsert配置 upsert 和批量 upsert
base-server/internal/data$ ent generate ./schema --feature sql/modifier --template ./ent/template --target ./ent
数据表中手动导入或者迁移的id可能与新增的id冲突导致插入失败,需手动重置序列的当前值
-- 1. 查询表中当前最大 ID SELECT MAX(id) FROM casbin_rules; -- 2. 通过 PostgreSQL 系统表 pg_sequences 直接获取序列的当前值 SELECT last_value FROM pg_sequences WHERE schemaname = 'public' AND sequencename = 'casbin_rules_id_seq'; -- 3. 重置序列起始值为当前最大 ID + 1 ALTER SEQUENCE casbin_rules_id_seq RESTART WITH {max_id + 1}; ALTER SEQUENCE casbin_rules_id_seq RESTART WITH 10001;
