You need to create a mongoose model after you create your schema, and then you can save it. Try something like this:
创建模式后，您需要创建一个 mongoose 模型，然后您可以保存它。尝试这样的事情：
var ProductSchema = new Schema({
name: String,
conditions: [{}],
colors: [{}]
});
var Product = mongoose.model('Product', productSchema);
var product = new Product({
name: req.body.name,
conditions: req.body.conditions,
colors: req.body.colors
});
product.save( function(error, document){ //callback stuff here } );
