Enter code here...

does anyone have experience with ttl for mongoose

[8:20 PM]

I am trying to set it for my schema to delete documents if the user is not premium at certain seconds, using the partialFilterExpression

[8:20 PM]

but the document is being deleted

[8:20 PM]

regardless the state of the user

[8:20 PM]

[8:21 PM]

[8:21 PM]

this is my schema

const postSchema = new mongoose.Schema(
 {
 title: { type: String },
 description: { type: String },
 image: { type: String },
 price: { type: String },
 location: { type: String },
 image: { type: Array },
 author: {
 type: String,
 ref: 'User'
 },
 authorPremium: {
 type: Boolean,
 default: false,
 index:true
 },
 reported: {
 type: Boolean,
 default: false
 },
 reportClear: {
 type: Boolean,
 default: false
 }
 },
 {
 timestamps: true
 }
);

// users who are premium will keep post for 120 days
// postSchema.index({createdAt: 1},{expireAfterSeconds: 360,partialFilterExpression : {authorPremium: true}});

// users who are not premium will have posts deleted after 20 seconds
postSchema.index({ createdAt: 1 }, { expireAfterSeconds: 20, partialFilterExpression: { authorPremium: false } });

module.exports = mongoose.model('Post', postSchema);
