sails.js mvc framework learning
目的：加快开发速度，总结使用方法：
menu list:
- custom controller
- custom 模块使用
- custom model
- custom middleware
- custom
- service
关于启动 ##：
config/connection -- db connection
入口: app.js
config/bootstrap - 启动入口app.js 后的
config/policies 配置
bin/*.json
关于DIY ##：
config/router
路由与对应的controller处理:
用命令行 & controller 变化
wade-mac:fin_server_invest mac$ sails generate controller mail sendmaillog
info: Created a new controller ("mail") at api/controllers/MailController.js!
路由总汇总：config/routes.js
想往常一样加：, 'GET /make/a/mail':"MailController.sendmaillog"
模块的使用： －－ 与以前一样
/**
* MailController
*
* @description :: Server-side logic for managing mails
* @help :: See http://links.sailsjs.org/docs/controllers
*/
module.exports = {
/**
* `MailController.sendmaillog()`
*/
sendmaillog: function (req, res) {
var log4js = require('log4js');
var logger = log4js.getLogger();
logger.debug("Some debug messages");
return res.json({
todo: 'sendmaillog() is not implemented yet!'
});
}
};
model command ：
https://www.digitalocean.com/community/tutorials/how-to-create-an-node-js-app-using-sails-js-on-an-ubuntu-vps
$sails generate model user name:string email:string password:string
$sails generate controller user index show edit delete
middleware：
https://gist.github.com/mikermcneil/6255295
look at config/http.js
module.exports.http = {
/****************************************************************************
* *
* Express middleware to use for every Sails request. To add custom *
* middleware to the mix, add a function to the middleware config object and *
* add its key to the "order" array. The $custom key is reserved for *
* backwards-compatibility with Sails v0.9.x apps that use the *
* `customMiddleware` config option. *
* *
****************************************************************************/
middleware: {
/***************************************************************************
* *
* The order in which middleware should be run for HTTP request. (the Sails *
* router is invoked by the "router" middleware below.) *
* *
***************************************************************************/
order: [
'startRequestTimer',
'cookieParser',
'session',
'myRequestLogger',
'bodyParser',
'handleBodyParserError',
'compress',
'methodOverride',
'poweredBy',
'$custom',
'router',
'www',
'favicon',
'404',
'500'
],
/****************************************************************************
* *
* Example custom middleware; logs each request to the console. *
* *
****************************************************************************/
myRequestLogger: function (req, res, next) {
console.log("Requested :: ", req.method, req.url);
return next();
},
/***************************************************************************
* *
* The body parser that will handle incoming multipart HTTP requests. By *
* default as of v0.10, Sails uses *
* [skipper](http://github.com/balderdashy/skipper). See *
* http://www.senchalabs.org/connect/multipart.html for other options. *
* *
***************************************************************************/
bodyParser: require('skipper')
},
/***************************************************************************
* *
* The number of seconds to cache flat files on disk being served by *
* Express static middleware (by default, these files are in `.tmp/public`) *
* *
* The HTTP static cache is only active in a 'production' environment, *
* since that's the only time Express will cache flat-files. *
* *
***************************************************************************/
cache: 31557600000
};
上面的是所有的路由都经过的middleware
疑问：控制某个路由/a 经过middleware: [a, b, c ] , 某个路由/b 经过middleware: [a, c ]
一些文件夹
- service 本项目单独的业务逻辑
- lib 存放一些共用的lib
- data 存放常用配置、数据
CRUD
CRUD -- model
CRUD -- 尽量使用 native
- 速度快
- 适合复杂操作
CRUD -- 坑
- 并发：使用findandmodify & update(upsert) & findorcreate
//findandmodify
Order.native(function (err, collection) {
collection.findAndModify(query, null, {$set: update_data}, {'new': false}, function (err, newResult, detail) {//update upsert
User_account_cashflow.native(function(err, colletion){
colletion.update(query, {$set: cashflow },{upsert:true, multi:false} , function(err, effectNum, result){
callback(err, cashflow, result.updatedExisting);
});
});
