mongoose: Referencing schema in properties or arrays Written on February 01, 2015 . The issue is permissions: { type: Array, default: [], enum: PERMISSIONS }. Mongoose document arrays have a special id method for searching a document array to find a document with a given _id.
Apologies if that's the case.

const polygonSchema = new mongoose.Schema({ type: { type: String, enum: ['Polygon'], required: true}, coordinates: { type: [ … Numbers have min and max validators. All SchemaTypes have the built-in required validator.
Below is how you create a Mongoose schema where coordinates is a triple nested array of numbers.

mongoose: Referencing schema in properties or arrays Written on February 01, 2015 . Below is how you create a Mongoose schema where coordinates is a triple nested array of numbers. It includes built-in type casting, validation, query building, business logic hooks and more, out of the box.

var mySchema = new Schema({ label: [{type:String, enum: ['enumVal1','enumVal2']}] }); Small snippet of conversation on irc which might give direction: aheckmann: file an issue, i think its b/c the validation isn't set on the array I appreciate it, but there was no way around it so we we ended up migrating all codebase to String and it is working without any issue now. uri(s) «String» [options] «Object» passed down to the MongoDB driver's connect() function, except for 4 mongoose-specific options explained below.

When using a NoSQL database like MongoDb, most of the time you'll have documents that contain all properties by itself. I don't personally like ENUM values because if I add another value to the ENUM, I have to recompile the entire application again and deploy. I am glad to see this feature though, now i can save disk space by using more numeric enums for hardcoded values @r3wt we'll have enum for numbers in 5.8.0, see #8139.

Therefore an array is always initialized as "empty" unless of course you deliberately put something in it. Mongoose has several built-in validators. [options.bufferCommands=true] «Boolean» Mongoose specific option. an enum that can define a list of strings that are valid; The Number and Date properties both support specifying a minimum and maximum value that is allowed for that field. Creating an array of enum doesn't appear to be implemented, would be nice to have!

enum: all types: array of values: Enumerates all possible values of the field: type: all types: string or array of unique strings: Enumerates the possible JSON types of the field.

Polygons are tricky because they use triple nested arrays.

So neat, but doesn't work for me (mongoose 3.6.20): for the path() function, my enum fields must be prefixed with ".enum", and there is no "enumValues" property on the returned object. enum is a no-op on arrays of non-strings, and before 5.0.6 setting enum on an array did nothing. When using a NoSQL database like MongoDb, most of the time you'll have documents that contain all properties by itself.

var mySchema = new Schema({ label: [{type:String, enum: ['enumVal1','enumVal2']}] }); Small snippet of conversation on irc which might give direction: aheckmann: file an issue, i think its b/c the validation isn't set on the array Strings have enum, match, minlength, and maxlength validators.

Default values really don't work with arrays, unless of course it is a document within the array and you want to set a default property for that document when added to the array. Please see the Mongoose SchemaTypes docs for more info and examples. Mongoose provides a straight-forward, schema-based solution to model your application data. var doc = parent.children.id(_id); Adding Subdocs to Arrays. Why I don't like ENUM.

I'm trying to remove an object from an array in a document using mongoose. const polygonSchema = new mongoose.Schema({ type: { type: String, enum: ['Polygon'], required: true}, coordinates: { type: [ …

Mongoose.prototype.connect() Parameters. Set to false to disable buffering; on all models associated with this connection. The required validator uses the SchemaType's checkRequired() function to determine if the value satisfies the required validator. Polygons are tricky because they use triple nested arrays.
