node. JS---Sails project development (4)---Configure MongoDB database connection

1, the installation of sails to MONGO dependence

NPM Install Sails-mongo--save

2. Configure MONGO Connection

Modify Config/connections.js:

Module.exports.connections = {somemongodbserver: {    adapter: ' Sails-mongo ',    Host: ' 127.0.0.1 ',    port: 27017,    User: ' Test ',//optional    password: ' Test ',//optional    database: ' Sails '//optional  }};

3, the basic configuration of the model layer

Modify Config/models.js, configure the connection database bit MongoDB for the model, and add Updatedat and Createdat properties for each model:

Module.exports.models = {  migrate: ' Alter ',  ' connection ': ' Somemongodbserver ',  autocreatedat:true,  Autoupdatedat:true};

Here are some instructions for migrate:

Safe-never auto-migrate My database (s). I will does it myself (by hand) [does not automatically merge data and requires manual control]
Alter-auto-migrate, but attempt to keep my existing data (experimental) [automatically merged with old data, when a new field is added, the datasheet will not be deleted, it is recommended]
Drop-wipe/drop all my data and rebuild models every time I lift sails[Delete datasheet, create new table, insert new data]

4, modify the Config/env/development.js

Module.exports = {  models: {    connection: ' Somemongodbserver '}  };

5. Next, we start sails

Sails lift
