Cannot lift sails: localhost undefined

Question

Cannot lift sails: localhost undefined

I'm on a project using a stack that includes PostgreSQL, NodeJS, SailsJS, and BackboneJS. I pulled the client and server repos from git and I navigate into the server for the project and try to run it:

sails lift

Then I get this error:

/Users/$USER/Documents/Code/$APP/config/adapters.js:39

    host: mc.dbSettings.host,

TypeError: Cannot read property 'host' of undefined

Where mc is a var that is set to point to another mainConfig.js file using a require statement. Opening that file I see that dbSettings is defined as:

dbSettings: {
    host: "localhost",
    user: "_appName_",
    password: "_password_",
    dbName: "_appDB_"
},

and sails cannot initialize because there is no localhost, or it doesn't know what it is? Please help.

javascript
node.js
postgresql
localhost
sails.js

Answer 1

If you're requireing a file and getting an "undefined" error trying to access its contents, it's possible you haven't exported the file contents properly. Your config file should look something like:

module.exports = {

    dbSettings: {
        host: "localhost",
        user: "_appName_",
        password: "_password_",
        dbName: "_appDB_"
    },

    ...

};

Note the module.exports. If that's missing, or if it's namespaced (like module.exports.foo) or if that dbSettings object is nested inside something else, it won't work.

dbSettings is undefined. So that must mean that it's not being found by SailJS. If you are using v.1.0 then you need to define your settings in connections.js instead of adapters.js. I'm assuming Sails will not be able to find your configuration otherwise.
