node.js - 在 Mongoose 中填写所有必填字段

Question

Mongoose 似乎默认使所有字段都不需要。有没有办法在不更改每个字段的情况下使所有字段成为必需的:

Dimension = mongoose.Schema(
  name: String
  value: String
)

到

Dimension = mongoose.Schema(
  name:
    type: String
    required: true
  value: 
    type: String
    required: true
)

因为我有很多，它会变得非常难看。

你可以这样做:

var schema = {
  name: { type: String},
  value: { type: String}
};

var requiredAttrs = ['name', 'value'];

for (attr in requiredAttrs) { schema[attr].required = true; }

var Dimension = mongoose.schema(schema);

或者对于所有属性(使用下划线，这很棒):

var schema = {
  name: { type: String},
  value: { type: String}
};

_.each(_.keys(schema), function (attr) { schema[attr].required = true; });

var Dimension = mongoose.schema(schema);
