MongoDB嵌入式文档作为键值数组

Question

I'm trying to use mongoose to represent an association between 3 schemas:

Schema1: {
    //fields
}

Schema2: {
    //fields    
}

Scehma3: {
   //fields
   - [Scehma1:Scehma2] - collection of key-val elements
     where the key is a ref to schema1 and val is ref to scehma2
}

Does mongoose support this king of association without creating a schema4?

Answer 1

You can't create ambiguous keys in mongoose because its whole purpose is to handle your document structure for you. What you can do, however, is create an array of objects.

Schema4: {
  schemaRefs: [{
    refToSchema1: {type: mongoose.Types.ObjectId, ref: 'Schema1'},
    refToSchema2: {type: mongoose.Types.ObjectId, ref: 'Schema2'}
  }]
}

For future reference it's far easier to understand your question when you provide real examples rather than false names. Even if you falsify your example (eg some relationship between restaurants and customers or something) it's much easier to understand the relationship you're trying to make.
