如何让Entity Framework在将所有字符串存储到数据库之前自动修剪它们？
答案 0 :(得分：9)
您可以使用class LineItem {
int id
Header header
static mapping = {
table "line_item"
columns {
header {
column name: 'sale_id'
column name: 'store_id'
}
}
id composite: ['id', 'header.station.storeId'] // something like this where I have to include store_id along from header table which instead from station table should be included as a part of composite key
}
}
拦截对数据库的所有调用。然后修剪任何传递的参数。
