supergoose Build Status

Mongoose simple plugin adding some handy functions.

Model functions

Relationship creator functions

Installation

npm install supergoose

Usage

Initialization

Use mongoose's plugin method to extend your models with supergoose

var supergoose = require('supergoose')
var ClickSchema = new Schema({ ... });
ClickSchema.plugin(supergoose, [options]);
var Click = mongoose.model('Click', ClickSchema)

Arguments

  • supergoose - The supergoose function
  • options - Options object

    Valid Options

    • instance - The instance of mongoose used in the application (Required for Schema functions)
    • messages - Object of custom messages (Required for errors function)

      findOrCreate()

      Adds find or create functionality to mongoose models. This is handy for libraries like passport.js which require it

      Click.findOrCreate({ip: '127.0.0.1'}, function(err, doc) {});
      Click.findOrCreate({ip: '127.0.0.1'}, {browser: 'Chrome'}, function(err, click) {})

      Arguments

      • query - Conditions with which to search for document
      • [doc] - Document to insert if document not found
      • [options]
      • callback
      • Valid Options

        • upsert - updates the object if it exists. Default: false

        errors

        Parses the complex validation errors return from mongoose into a simple array of messages to be displayed as flash messages or something similar

        var supergoose = require('supergoose')
        var ClickSchema = new Schema({ip: {type: String, required: true}});
        Click.plugin(supergoose, {messages: {'required': '%s is a required field'}});
        var Click = mongoose.model('Click', ClickSchema);

        The Click model now has an errors static method

        Click.create({}, function(err, click) {
          if(err) {
            Click.errors(err, function(messages) {
              console.log(messages);
              // outputs ['ip is a required field']
            })
          }
        });

        Arguments

        • errors - error returned from mongoose command
        • callback

        Relationship Creator Functions

        • parentOf / oneToMany - Creates a one to many relationship
        • childOf / manyToOne - Creates a many to one relationship
        • hasA / oneToOne - Creates a one to one relationship
        • hasMany / manyToMany - Creates a many to many relationship

        Arguments

        • modelName - Name of related Model
        • [myPath] - Name of path on this schema that refers to related Model. (If not provided, a default is used based on the model name. '_clicks' for the above example)

        Returns

        • Relationship

        Relationship

        When a relationship is created, it adds a path that refers to the related model on the schema that creates it. The relationship object has one property:

        enforceWith

        var supergoose = require('supergoose')
        var mongoose = require('mongoose')
        
        var ClickSchema = new Schema({ip: {type: String, required: true}, _user: {type: ObjectId}});
        var UserSchema = new Schema({name: String})
        
        UserSchema.plugin(supergoose, {instance: mongoose});
        UserSchema.parentOf('Click', 'clickCollection').enforceWith('_user')
        

        Arguments

        • itsPath - Name of path on related model that refers back to this schema.
        • [options]

          Valid Options
