mongoose-parent-acl

Forked from https://github.com/scttnlsn/mongoose-acl

Usage

var mongoose = require('mongoose');
var acl = require('mongoose-parent-acl');
 
var WidgetSchema = new mongoose.Schema({ … });
WidgetSchema.plugin(acl.object);
 
var UserSchema = new mongoose.Schema({ … });
UserSchema.plugin(acl.subject);

Methods

The plugin adds accessor methods to the object for getting and setting permissions of a particular key:

var widget = new Widget({ … });
 
widget.setAccess('foo', ['a', 'b']);
widget.getAccess('foo'); // => ['a', 'b']

Or getting all keys with given permissions:

widget.keysWithAccess(['a']); // => ['foo']

There are also convenience methods added to the subject for getting and setting the permissions for a given object:

var user = …;
 
user.setAccess(widget, ['read', 'write', 'delete']);
user.getAccess(widget); // => ['read', 'write', 'delete']

We can query for all objects to which a particular subject has access:

Widget.withAccess(user, ['read']).exec(function(err, widgets) {
    ...
});

Options

Object

We can specify the path in which the ACL will be stored (by default it will be available at _acl):

WidgetSchema.plugin(acl.object, {
    path: '_acl'
});

Subject

Each subject is referred to in an ACL by a unique key (by default it is of the form subject:<subject _id>). This can be customized by specifying a key option:

UserSchema.plugin(acl.subject, {
    key: function() {
        return 'user:' + this._id;
    }
});

We can also specify additional ACL keys to which a subject has access. For example, suppose a user optionally belongs to a number of roles:

UserSchema.plugin(acl.subject, {
    additionalKeys: function() {
        return this.additional.map(function(key) {
            return 'additional:' + key;
        });
    }
});

There is one special key referred to as the public key. If set, the associated permissions will apply to all subjects:

UserSchema.plugin(acl.subject, {
    public: '*'
});
