数据库模型
/model/db.js 数据库操作类，完成链接数据库和数据库的增删查改
查询表
select:function(tableName,callback,where,field){
field=field ? field : '*';
var sql="select "+field+" from "+this.C.DB_PRE+tableName;
if(where){
sql+=" where "+where;
}
this.db.query(sql,callback);
}
添加记录
add:function(tableName,tableData,callback){
var sql="insert into "+this.C.DB_PRE+tableName;
var clumn='';
var value='';
for(var key in tableData){
clumn+=","+key;
value+=",'"+tableData[key]+"'";
}
clumns="("+clumn.substr(1)+")";
values="("+value.substr(1)+")";
sql=sql+clumns+"values"+values;
console.log(sql);
this.db.query(sql,callback);
}
修改记录
update:function(tableName,tableData,where,callback){
var sql="update "+this.C.DB_PRE+tableName+" set ";
var clumns="";
for(var key in tableData){
clumns+=","+key+"='"+tableData[key]+"'";
}
clumns=clumns.substr(1);
sql+=clumns+" where "+where;
console.log(sql);
this.db.query(sql,callback);
}
删除记录
delete:function(tableName,where,callback){
var sql="delete from "+this.C.DB_PRE+tableName+" where "+where;
console.log(sql);
this.db.query(sql,callback);
}
业务模型
例如分类模型，/model/category.js
module.exports={
getAllList:function(){
db.select("category",function(err,list){
console.log(list);
});
},
addCate:function(data){
db.add("category",data,function(err,list){
console.log(err);
});
},
saveCate:function(data,where){
db.update("category",data,where,function(err,list){
console.log(err);
});
},
delCate:function(where){
db.delete("category",where,function(err,list){
//console.log(err);
});
}
};
控制器
先在公共函数文件增加一个调用模型的方法
model:function(name){
return require("http://www.jsgho.com/help/model/"+name);
}
控制器调用业务模型
var router=express.Router();
router.get('http://www.3lian.com/',function(req,res,next){
F.model("category").getAllList();
//F.model("category").addCate({"name":"测试"});
//F.model("category").saveCate({"name":"测试1"},"id=4");
//F.model("category").delCate("id=4");
res.render("home/index");
});
module.exports=router;
