“accessibleFieldsPlugin”不包含虚拟字段

Question

Using CASL with Express and Mongoose, when I use accessibleFieldsPlugin , the virtual fields aren't included with the results.

Is this a bug, or I have to do some workaround to get them included also? What is the best thing to do in this situation?

Person model:

const personSchema = new mongoose.Schema({
    fullName: {
        type: String,
        required: true
    },
    picture: {
        type: String,
        required: true
    },
    ....
}, {
    timestamps: true,
    toObject: { virtuals: true },
    toJSON: { virtuals: true }
});

personSchema.virtual('picturePath').get(function () {
    if (this.picture != null) {
        return path.join('/', uploadPath, this.picture)
    }
    return null;
});

personSchema.plugin(accessibleRecordsPlugin);
personSchema.plugin(accessibleFieldsPlugin);

module.exports.Person = mongoose.model('Person', personSchema, 'person');

Answer 1

It might be easier to maintain if you configure the plugin globally.

Something like this would add all the virtual props (FYI, id is already included).

mongoose.plugin(accessibleFieldsPlugin, { 
  getFields: (schema) => Object.keys({...schema.paths,...schema.virtuals})
})

Using @Stotskyi help, I manage to solve this problem like this (If there is a better code, I highly appreciate any help):

const personSchema = new mongoose.Schema({
    fullName: {
        type: String,
        required: true
    },
    picture: {
        type: String,
        required: true
    },
    ....
}, {
    timestamps: true,
    toObject: { virtuals: true },
    toJSON: { virtuals: true }
});

personSchema.virtual('picturePath').get(function () {
    if (this.picture != null) {
        return path.join('/', uploadPath, this.picture)
    }
    return null;
});

personSchema.plugin(accessibleRecordsPlugin);

// Here is the new code
const customAccessibleFieldsPlugin = new accessibleFieldsPlugin(personSchema, {
    getFields(schema) {
        const paths = Object.keys(schema.paths);
        paths.push('id');
        paths.push('picturePath');
        return paths;
    }
});
personSchema.plugin(() => customAccessibleFieldsPlugin);

module.exports.Person = mongoose.model('Person', personSchema, 'person');
