How to handle nested field? The Anagram is not created under info.name1

[egonzal93]

My model looks like this:

const taskSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  info: {
    name1: String,
    title: String,
    version: String,
    description: String
  },
  completed: {
    type: Boolean,
    required: true
  },
  user: {
    type: mongoose.Schema.Types.ObjectId,
    ref: 'User'
  }
}, {
    timestamps: true
});

taskSchema.plugin( mongoose_fuzzy_searching, {
    fields: [{
        name: 'info.name1',
        minSize: 2,
        prefixOnly: false,
    }]
    }
);

I saved :

 const debug = require('debug')('add_new_task');
    const input = {
        name: taskTitle,
        info: {
            name1: "Army Ants1",
            title: "Army Ants2",
            version: "Army Ants3",
            description: "Army Ants4"
        },
        completed: false
    };
    try {
        const user = await User.findOne({email: taskEmail});
        debug(`user ${JSON.stringify(user, null,2)}`);
        const task = new Task({...input, user: user.id});
        const result = await task.save();
        user.tasks.push(result.id);
        await user.save();
        debug(`result=${JSON.stringify(result, null,2)}`);
        return result;
    } catch (error) {
        console.log(error);
    }

The Anagram is not created under info.name1:

add_new_task result={
add_new_task "info": {
add_new_task "name1_fuzzy": [
add_new_task ""
add_new_task ],
add_new_task "name1": "Army Ants1",
add_new_task "title": "Army Ants2",

add_new_task "updatedAt": "2020-11-17T00:02:22.006Z",
add_new_task "__v": 0
add_new_task } +167ms

name1_fuzzy is empty.

According to the documentation you need to use keys for nested attributes.
https://github.com/VassilisPallas/mongoose-fuzzy-searching#object-field

[egonzal93]

I used keys:

const mongoose = require('mongoose');
const mongoose_fuzzy_searching = require('mongoose-fuzzy-searching');

const taskSchema = new mongoose.Schema({
name: {
type: String,
required: true
},
info: {
name1: String,
title: String,
version: String,
description: String
},
completed: {
type: Boolean,
required: true
},
user: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
}
}, {
timestamps: true
});

taskSchema.plugin( mongoose_fuzzy_searching, {
fields: [{
name: 'info',
keys: [
'name1',
'title',
'version',
'description'
]
}]
}
);

module.exports = mongoose.model('Task', taskSchema);

Saved it:

addNewTask = async () => {
const debug = require('debug')('add_new_task');
const input = {
name: taskTitle,
info: {
name1: "Army1 Ants1",
title: "Army1 Ants2",
version: "Army1 Ants3",
description: "Army1 Ants4"
},
completed: false
};
try {
const user = await User.findOne({email: taskEmail});
debug(user ${JSON.stringify(user, null,2)});
const task = new Task({...input, user: user.id});
const result = await task.save();
user.tasks.push(result.id);
await user.save();
debug(result=${JSON.stringify(result, null,2)});
return result;
} catch (error) {
console.log(error);
}

but still anagrams are not getting saved to mongo:

NVM, it worked this time: Thanks for the response. Good night.

It looks like the old key indexes needs to be dropped when you change keys.

[VassilisPallas]

Yes indeed. I'm currently working on deleting the indexes every time.

[egonzal93]

Do you know when you plan on releasing an update? Should the index expire so that it can be rebuilt?

[VassilisPallas]

I think we can expire only date indexes. The ideal scenario is every time you restart your application to delete manually the indexes. I will try to delete them when the plugin is initialized.
However, I don't know if this is possible
