咕噜任务砸猫鼬数据库 [英] Grunt task to drop mongoose database

问题描述

我试图创建一个任务咕噜猫鼬通过删除MongoDB数据库。该连接悬挂，我必须强制退出，这是不实际删除数据库或输出错误。

  VAR DB =要求（'./ DB /模式'）;grunt.registerTask（'砸'，'删除数据库'，函数（）{
  //异步模式
  VAR完成= this.async（）;  db.mongoose.connection.db.dropDatabase（功能（错误）{
    如果（ERR）{
      的console.log（ERR）;
    }其他{
      的console.log（'成功删除数据库'）;
    }
    db.mongoose.connection.close（完成）;
  }）;}）;
 

输出

  $咕噜下降
运行滴的任务
已成功连接到：MongoDB中：//本地主机/测试
^ C
 

解决方案

终于找到了解决我这里的问题：的 https://groups.google.com/forum/?fromgroups=#!topic/mongoose-orm/Cck_VND80r8 只好来包装connection.on

  grunt.registerTask（'降'，'删除数据库'，函数（）{
//异步模式
VAR完成= this.async（）;db.mongoose.connection.on（开放，函数（）{
  db.mongoose.connection.db.dropDatabase（功能（错误）{
    如果（ERR）{
      的console.log（ERR）;
    }其他{
      的console.log（'成功删除数据库'）;
    }
    db.mongoose.connection.close（完成）;
  }）;
}）;
}）;
 

I'm trying to create a grunt task to drop a mongodb database through mongoose. The connection is hanging and I have to force quit and it is not actually dropping the database or outputting an error.

var db = require('./db/schema');

grunt.registerTask('drop', 'drop the database', function() {
  // async mode
  var done = this.async();

  db.mongoose.connection.db.dropDatabase(function(err) {
    if(err) {
      console.log(err);
    } else {
      console.log('Successfully dropped db');
    }
    db.mongoose.connection.close(done);
  });

});

Output

$ grunt drop
Running "drop" task
Successfully connected to: mongodb://localhost/test
^C

解决方案

Finally found the solution to my problems here: https://groups.google.com/forum/?fromgroups=#!topic/mongoose-orm/Cck_VND80r8 Had to wrap everything in connection.on

grunt.registerTask('drop', 'drop the database', function() {
// async mode
var done = this.async();

db.mongoose.connection.on('open', function () { 
  db.mongoose.connection.db.dropDatabase(function(err) {
    if(err) {
      console.log(err);
    } else {
      console.log('Successfully dropped db');
    }
    db.mongoose.connection.close(done);
  });
});
});
