schema: -> a string array based on an enum

[Thibault]

Hi,

I would like to know if it is possible to define something like that:

var User = new Schema({
...
roles: [{ type: String, enum: ['admin', 'creator', 'contact'] }]
...
});

because when I try to insert document with an array of role ( ...
'roles':['creator'] ... ) I've got this exception: uncaught:
CastError: Cast to undefined failed for value "undefined"

However to solve it I create another schema:

var Role = new Schema({
name: { type: String, enum: ['admin', 'creator', 'contact'] }
});

And change the user schema like that:
var User = new Schema({
...
roles: [Role]
...
});

So, when I insert data I have to do like that ... 'roles':
[{'name':'creator'}] ... I's working but I found it no very smart.

Hace you got another solution?

thx

defining the "roles" as type String with an enum seems to be a good way to cast that value.  You can also add a "default" property as one of the enum values if you'd like.  You can see this in action here: http://nodetuts.com/tutorials/21-nodejs-mongodb-and-mongoose-11.html#video

Hi,
Thx for the response, finaly found a solution:

// i define roles as an array

var User = new Schema({
...

roles: [String]
...

});

// and validate the values match the content of the enum:
User.path('roles').validate(function(roles) {
var refs = ['creator', 'admin', 'contact'];
roles.forEach(function(role){
var valid = false;
refs.forEach(function(ref){
if(ref == role) {
valid = true;
return;
}
});
if(!valid) return false;
});
return roles.length > 0;
}, 'roles not valid');
