provide initial data for mongoose models


// mongoose is connection and models are already registered
var path = require('path')
  , msf = require('mongoose-simple-fixtures')
  , dir = path.resolve(__dirname, "./fixtures")

msf(dir, function(err, results) {
    if (err) console.log("loading data failed");


msf([mongoose], directory, [validate], [callback])

- mongoose - optional reference to mongoose - directory - the path to the data, i.e. ./fixtures - validate - optional boolean to disable schema validation (default: null) - callback - optional function(err, results) {}
callback receives a results array. Each object in the array has a name property with the name of the model and three values, added, failed, and skipped, indicating the number of documents in that collection that were saved, failed to save, or already exist. (mongoose-simple-fixtures will not add duplicate data by attempting to find a record before the insertion.) The records inserted are also returned.
validate indicates whether schema validation should occur before inserting. For example, object reference validators which ensure the referenced document exists may prevent data from being loaded (i.e. cylical dependencies). To prevent this, invoke with the value of false to temporarily suspend the validators. After loading the data, the schema validation will be set to it's previous value. If no value is specified, mongoose-prime will not modify the model's validation settings. (cf. #validateBeforeSave)


mongoose-simple-fixtures supports simple JSON files as well as extended-JSON files, the sort that mongoexport generates.
Each filename in the directory must correspond to the model name in mongoose. For example, if you used the directory fixtures and it contained two files:
$ ls fixtures/
templates.json users.json

then mongoose-simple-fixtures would look for two models on the mongoose reference called templates and users. If those models do not exist, the data loading will fail. Any files not ending in .json are skipped.


mongoose-simple-fixtures utilizes mongoose-prime under the hood.
