如何在nodejs中编写mongoosastic中的映射
如何在nodejs中编写mongoosastic中的映射
提问于 2015-08-20 23:01:57
实际上，我现在想从一些字段中删除索引，有没有人能告诉我，如果我的代码被赋予了bel，我怎么才能写出映射；，有没有人能告诉我这里面有什么问题，或者有没有人能告诉我，这样做的正确方法是什么？
Blog.createMapping(function(err, mapping){
if(err){
console.log('error creating mapping (you can safely ignore this)');
console.log(err);
}else{
mapping: {
properties: {
jeb_no: {
index: "no"
}
}
}
console.log('mapping created!');
console.log(mapping);
}})；
提前谢谢你。

});
MovieSchema.plugin(mongoosastic);
Movie = module.exports = mongoose.model('Movie', MovieSchema);
Movie.createMapping({
