a SQL mapping dao framework for node.js
不好意思,又来问了。
1.我看todo那个demo里model对应了一个domain,这个一定要建立吗?没看到bearcat-dao里有提到呢。
2.domainDaoSupport里的batchAdd有点不理解,如果我的mysql表主键id设置为自增长,为什么还需要一个叫做idgenerator的表来进行计数呢????
DemoDao.prototype.transaction = function(txStatus){
this.domainDaoSupport.transaction(txStatus);
return this;
}
这是我的dao .
this.demoDao.transaction(txStatus).update();
这是我在service中调用 , 我想知道 这个 txStatus是什么, 应该在哪获取 并传入 。
$mid
、$table
等非数据属性,能够移除?$default
的function如何使用,例如设置时间字段为当前时间?$default
的话会把$type
这些作为值存入数据库,必须指定default,能够优化?如题 连接mysql的字符编码设置怎么设置啊,中文乱码啊 求救
when developing using the transaction Aspect. it is useless if you use a one ...Transaction method within an other
currently i have a problem like line and dogs, where each dog has its line.
toimplement the createDogTransaction, i wanted to reuse the createLineTransaction Method.
but then I actually have two transactions
but when explict indicate the select item, can return result
BeanBuilderUtil.buildObjectList = function(results, func, fields) {
var r = [];
for (var i = 0; i < results.length; i++) {
var result = results[i];
var beanObject = new func();
for (var j = 0; j < fields.length; j++) {
var field = fields[j];
var name = field.getName();
if (result[name]) {
//如果result[name]存的为int型数据,且为0,或者boolean型并且为false的话,是存在错误的,无法正常获取数据
beanObject[name] = result[name];
}
}
r.push(beanObject);
}
return r;
}
hi
bearcat-dao导入数据库表的json文件中,beans的func属性,如果node_modules目录和该json文件不在同一级目录,该属性值需要怎么修改,求教啊
比如:
context_test;json 在/usr/local/test/context_json 目录
node_modules在/usr/local/test目录
我的表主键id设为自增,
然后用add方法和batchAdd方法添加数据的时候,返回的信息中,为什么id都是entity里的0?
如何才能返回数据本身的自增id?
不会是需要插入后在查一遍吧??
