Managing Labels and Properties

note

In RushDB, labels and properties are crucial for defining and organizing your data models. Labels act as categories or tags for your records, while properties define the structure and data types of the records themselves. This section covers how to manage labels and properties using the RushDB SDK.

Understanding Labels and Properties​

Labels​

Labels are used to categorize Records in RushDB. Each model or record type is associated with a label, which helps in organizing and querying the data.

Properties​

Properties are the individual fields within a record. Each property has a type, such as string, number, or datetime, and can have additional attributes like required, unique, and default.

Managing Labels​

You can manage labels using the labels property in the RestAPI class. This allows you to find labels associated with your records.

Finding Labels​

The find method under labels allows you to search for labels based on specific criteria.

Example​

Finding labels with specific criteria:

const labelSearchCriteria = {
  where: {
    $OR: [
        {
            name: {
                $startswith: 'author'
            }
        },
        {
            title: { 
                $contains: 'Guide' 
            } 
        }
    ]
  }
};

const labels = await db.labels.find(labelSearchCriteria);
// Expected output:
// {
//   success: true,
//   data: {
//     author: 12,
//     post: 14
//   }
// }

Managing Properties​

Properties of records can be managed using the properties property in the RestAPI class. This includes actions like finding properties and their values, deleting properties, and updating property values.

Finding Properties​

The find method under properties allows you to retrieve properties of records based on specified criteria.

Example​

Finding properties of a record:

const propertySearchCriteria = {
  where: {
    model: 'author'
  }
};

const properties = await db.properties.find(propertySearchCriteria);
// Expected output:
// {
//   success: true,
//   data: [
//     {
//       id: 'property_id_1',
//       name: 'name',
//       type: 'string',
//     },
//     {
//       id: 'property_id_2',
//       name: 'email',
//       type: 'string',
//     }
//   ]
// }

Finding Property Values​

The values method retrieves the values of properties for a specific record.

Example​

Retrieving property values for a property:

const propertyValues = await db.properties.values('property_id');
// Expected output:
// {
//   success: true,
//   data: {
//     id: 'property_id',
//     name: 'age',
//     type: 'number',
//     values: [25, 30, 35, 40],
//     max: 40,
//     min: 25
//   }
// }

Deleting Properties​

The delete method removes properties from a record.

Example​

Deleting a property from a record:

await db.properties.delete('property_id');

Conclusion​

Managing labels and properties effectively allows for better organization and retrieval of your data in RushDB. This section covered the fundamental operations for handling labels and properties, providing you with the tools to maintain a well-structured and searchable data environment.
