Allow object of objects within inputs in action - node.js

Question

I'm wondering how I have objects of objects as inputs in an action - for example,
module.exports = {
friendlyName: 'Signup',
description: 'Signup a user for an account.',
inputs: {
bride: {
firstName: {
description: 'The first name of the bride',
type: 'string',
required: true
}
},
groom: {
lastName: {
description: 'The first name of the groom',
type: 'string',
required: true
}
}
}
exits: {},
fn: async function (inputs, exits) {
sails.log.debug(inputs.bride.firstName); // I would like to be able to reference input like this
return exits.success();
}
};
How can I do this and access inputs.bride.firstName (instead of having to do inputs.brideFirstName)?
I receive the following error trying to do this:
'Invalid input definition ("bride"). Must have `type`, or at least some more information. (If you aren\'t sure what to use, just go with `type: \'ref\'.)' ] } }

Another way is to implement a custom validation with objects of objects
module.exports = {
friendlyName: 'Signup',
description: 'Signup a user for an account.',
inputs: {
bride: {
description: 'The first name of the bride',
type: 'json', // {'firstName': 'luis'}
custom: function(value) {
return _.isObject(value) && _.isString(value.firstName)
}
},
groom: {
description: 'The first name of the groom',
type: 'json', // {'lastname': 'lazy'}
custom: function(value) {
return _.isObject(value) && _.isString(value.lastName)
}
}
}
exits: {},
fn: async function (inputs, exits) {
sails.log.debug(inputs.bride.firstName); // luis
return exits.success();
}
};

You should use a json type for this case. Sails don't check attributes in json type.
module.exports = {
friendlyName: 'Signup',
description: 'Signup a user for an account.',
inputs: {
bride: {
description: 'The first name of the bride',
type: 'json', // {'firstName': 'luis'}
required: true
},
groom: {
description: 'The first name of the groom',
type: 'json', // {'lastname': 'lazy'}
required: true
}
}
exits: {},
fn: async function (inputs, exits) {
sails.log.debug(inputs.bride.firstName); // luis
return exits.success();
}
};
