Using different mongo database than admin in sails - sails.js

Question

I'm struggling to connect with sails to a mongodb database that uses a database for authentication named "dbadmin". Where I am DBA decided to have all users centralized in a users database.
I can connect to this "dbadmin" database but then sails complains it cannot create collections there.
How can I use an authentication database and then a different database for collections?

Answer 1

You can define two database connection in your connections config file and then you can pass the connection in your data model directly
see the example:
in your config file
// server/config/connections.js
dbadmin: {
adapter: 'sails-mongo',
host: 'dbadmin-host',
port: 27017,
user: 'username',
password: 'password',
database: 'dbadmin'
}
dbuser: {
adapter: 'sails-mongo',
host: 'dbuser-host',
port: 27017,
user: 'username',
password: 'password',
database: 'dbuser'
}
and now you can use in your model:
// server/api/models/AdminUser.js
module.exports = {
connection:'dbadmin',
attributes: {
name : { type: 'string' },
pass : { type: 'string' }
}
};
// server/api/models/Users.js
module.exports = {
connection:'dbuser',
attributes: {
name : { type: 'string' },
pass : { type: 'string' }
}
};
NOTE: you can not make any collection between this two model .

It turns out that using the URL for the connection has more possibilities. So all I had to do is append at the end authSource=dbadmin
module.exports = {
models: {
connection: 'mongoRM'
},
connections: {
mongoRM: {
adapter: 'sails-mongo',
url: 'mongodb://user:password#db_url:port/database?authSource=dbadmin'
}
}
}
