使用Mongoose包含对MongoDB数组的查询

Question

我正在尝试查询以下文档,并希望在"TaxonomyIDs"字段中列出包含TaxonomyID"1"的所有文档.

...
"Slug" : "videosecu-600tvl-outdoor-security-surveillance",
"Category" : "Digital Cameras",
"SubCategory" : "Surveillance Cameras",
"Segment" : "",
"Usabilities" : [ 
    "Dome Cameras", 
    "Night Vision"
],
"TaxonomyIDs" : [ 
    1, 
    12, 
    20, 
    21, 
    13
],
"Brand" : "VideoSecu",
...

完全卡住了!

Answer 1

Model.find({TaxonomyIDs: 1}, function(error, models) {
  //put code to process the results here
});

mongodb将上面的查询条件解释为"匹配TaxonomyIDs数组包含1的任何文档".
