[英]How do I write this in Bookshelfjs and knex
I'm making a simple session store from bookshelfjs
, but I need to set the timestamp column correctly. 我正在从一个简单的会话存储bookshelfjs
,但我需要正确设置时间戳列。 I'm trying to write the column's ttl with now() + ttl interval of 1ms, but I can't recall how to get it done, or how to trigger raw content for that column: 我试图用now()+ ttl间隔为1ms来写列的ttl,但是我不记得如何完成它或如何触发该列的原始内容:
var Session = Models.Bookshelf.Model.extend({
tableName: 'sessions',
idAttribute: 'id'
},{
get: Promise.method(function(sid){
console.log("Fetching SID = ", sid);
return new this({id: sid}).fetch();
}),
set: Promise.method(function(sid, session, ttl){
console.log("Setting SID = ", sid);
console.log("Setting SID session = ", session );
console.log("Setting SID ttl = ", ttl);
new this({id: sid}).save({session: session, expiry: "(now() + " + ttl + " * interval '1 ms')" });
}),
destroy: Promise.method(function(sid){
this.destroy({id: sid});
})
});
The original Query from koa-pg-session is: 来自koa-pg-session的原始查询是:
UPDATE %I.%I SET session = $1, expiry = (now() + $2 * interval '1 ms') WHERE id = $3;
I'm sure it's with Knex's raw query formatter, but I can't find the correct part in the documentation for setting a the column's value. 我确定它与Knex的原始查询格式化程序一起使用,但是我在文档中找不到用于设置列值的正确部分。 I don't want to write the full query in a string, I want to know how to do it for just the single column 'expiry'. 我不想在字符串中写完整的查询,我想知道如何仅对单列“ expiry”执行此操作。
我还没有测试过,请告诉我它是否有效(当然,您首先需要使用knex):
new this({id: sid}).save({session: session, expiry: knex.raw("(now() + " + ttl + " * interval '1 ms')") });
