I'm using Sails.js (0.9.8) and MongoDB (via the sails-mongo adaptor) to create a collection of pages that can be positioned in a tree-view. I would like to store the path of a page in an array of UUIDs
My model:
module.exports = {
schema: true,
attributes: {
uuid: {
type: 'string',
unique: true,
required: true,
uuidv4: true
},
name: {
type: 'string',
required: true,
empty: false
},
path: {
type: 'array',
required: true,
array: true
}
}
}
It works well when I save a 'root' page (the 'path' property has just one item because it's a root page. Here is what it was saved in MongoDB:
{
_id: ObjectId("52f853e9609fb6c0341bdfcc"),
createdAt: ISODate("2014-02-10T04:22:01.828Z"),
name: "Home Page",
path: [
"a2b23e1f-954b-49a3-91f1-4d62d209a093"
],
updatedAt: ISODate("2014-02-10T04:22:01.833Z"),
uuid: "a2b23e1f-954b-49a3-91f1-4d62d209a093"
}
But when I want to create a 'subpage' below my previous created page (Home Page/Products), I get this error:
MongoError: E11000 duplicate key error index: cms-project.item.$path_1 dup key: { : "a2b23e1f-954b-49a3-91f1-4d62d209a093" }
Here is the data I sent:
{ name: 'Products',
uuid: 'a004ee54-7e42-49bf-976c-9bb93c118038',
path:
[ 'a2b23e1f-954b-49a3-91f1-4d62d209a093',
'a004ee54-7e42-49bf-976c-9bb93c118038' ] }
I probably missed something but I don't know what. If I store the path in a string instead of an array, it work well, but I find it much less elegant and handy.
