How to get array index of nested object in autoform? - meteor

Question

I need to set slugs of my subcategories ,and i am using autovalue for this. I need to know the index of actual field for when i use arrays. There is a wild card for this?
Eg:
subcategories.$.subs.$.name
subcategories: {
type: [Object],
optional: true,
},
"subcategories.$.name": {
type: String,
optional: true,
},
"subcategories.$.slug": {
type: String,
optional: true,
autoform: {
omit: true
},
autoValue: function() {
if (this.field('subcategories.$.name').isSet) {
return s.slugify( (this.field('subcategories.$.name').value).toLowerCase() );
}
},
},
"subcategories.$.subs": {
type: [Object],
optional: true,
},
"subcategories.$.subs.$.name": {
type: String,
optional: true,
},
"subcategories.$.subs.$.slug": {
type: String,
optional: true,
autoform: {
omit: true
},
autoValue: function(i) {
if (this.field('subcategories.$.subs.$.name').isSet) {
return s.slugify( (this.field('subcategories.$.subs.$.name').value).toLowerCase() );
}
},
},
Thanks,

I got the expected result by changing the schema. Besides getting more organized, this.siblingField('name') works!
Code:
Categories = new Mongo.Collection('categories');
Schemas = {};
Schemas.Subs = new SimpleSchema({
"name": {
type: String,
optional: true,
},
"slug": {
type: String,
optional: true,
autoform: {
omit: true,
},
autoValue: function() {
if (this.siblingField('name').isSet) {
return s.slugify( (this.siblingField('name').value).toLowerCase() );
}
},
},
});
Schemas.Subcategories = new SimpleSchema({
"name": {
type: String,
optional: true,
},
"slug": {
type: String,
optional: true,
autoform: {
omit: true,
},
autoValue: function() {
if (this.siblingField('name').isSet) {
return s.slugify( (this.siblingField('name').value).toLowerCase() );
}
},
},
"subs": {
type: [Schemas.Subs],
optional: true,
},
});
Schemas.Categories = new SimpleSchema({
name: {
type: String,
},
slug:{
type: String,
unique: true,
index: 1,
autoform: {
omit: true
},
autoValue: function() {
if (this.field('name').isSet) {
return s.slugify( (this.field('name').value).toLowerCase() );
}
},
},
subcategories: {
type: [Schemas.Subcategories],
optional: true,
},
});
Categories.attachSchema(Schemas.Categories);
