koa-waterline-gowhich

Middleware for your hose

npm install koa-waterline-gowhich

Usage

//see example.js

function* (){
  var ctx            = this;
  var message        = 'This is an example';
  var commentCreated = yield ctx._waterline.collections.comments.create({message: message});
  // You can yield to the CRUD waterline functions because they are written as promises.
  console.log(commentCreated);
}

// OR

function* () {
  var waterline      = Waterline.init(injection);
  var message        = 'This is an example';
  var commentCreated = yield waterline.collections.comments.create({message: message});
}

• The model attributes of connection and adp must match the connection and adapter naming conventions when setting up your environment to inject into the middleware.

Example

var connections= {
  couch: {
    adapter: "couch",
    host: '127.0.0.1',
    port: '5984',
    username: '',
    password: ''
  },
  mongo: {
    adapter: "mongo",
    host: 'localhost',
    port: '27017',
    user: '',
    password: '',
    database: 'waterline'
  }
};

var adapters= {
  couch: require('sails-couchdb-orm'),
  mongo: require('sails-mongo')
};

var models = {
  "comments": {
    "adp": "couch",
    "connection": "couch",
    "properties": {
      "archived": {
          "type": "boolean",
          "defaultValue": false
      },
      "message": {
          "type": "string"
      }
    }
  },
  "history": {
    "adp": "mongo",
    "connection": "mongo",
    "properties": {
      "activity_id": {
        "type": "number",
        "enum": [
            "unique"
        ]
      }
    }
  }
};

var injection               = {};
injection.methods           = false;
injection.models            = models;
injection.adapters          = adapters;
injection.connections       = connections

app.use(waterline(injection));

##Attributes Models - Required

- Models must have an adp, connection, and the properties attributes with the same design pattern in the example above.

Adapters - Required

- The adapters refer to the connection adapters; this is required and while seeming redundant it is required to run waterline

Connections - Required

- The connection attributes are the setting parameters for the data models to create the waterline.

Methods - Optional

 - The methods attribute allows the injection of functions for virtual methods inside the model. An example of such an injection would something like this:

Methods Example:

 var methods = {
     history: function(){
     //virtual methods specific to the history model
     },
     comments: function(){
     //virtual methods specific to the comments model
     }
};
