Scope
This document provides a structured architectural overview of the leaveManagement microservice, detailing its configuration, data model, authorization logic, business rules, and API design. It has been automatically generated based on the service definition within Mindbricks, ensuring that the information reflects the source of truth used during code generation and deployment.
The document is intended to serve multiple audiences:
- Service architects can use it to validate design decisions and ensure alignment with broader architectural goals.
- Developers and maintainers will find it useful for understanding the structure and behavior of the service, facilitating easier debugging, feature extension, and integration with other systems.
- Stakeholders and reviewers can use it to gain a clear understanding of the service’s capabilities and domain logic.
Note for Frontend Developers: While this document is valuable for understanding business logic and data interactions, please refer to the Service API Documentation for endpoint-level specifications and integration details.
Note for Backend Developers: Since the code for this service is automatically generated by Mindbricks, you typically won’t need to implement or modify it manually. However, this document is especially valuable when you’re building other services—whether within Mindbricks or externally—that need to interact with or depend on this service. It provides a clear reference to the service’s data contracts, business rules, and API structure, helping ensure compatibility and correct integration.

Authentication & Security
- Login Required: Yes
This service requires user authentication for access. It supports both JWT and RSA-based authentication mechanisms, ensuring secure user sessions and data integrity. If a crud route also is configured to require login, it will check a valid JWT token in the request query/header/bearer/cookie. If the token is valid, it will extract the user information from the token and make the fetched session data available in the request context.
Service Data Objects
The service uses a PostgreSQL database for data storage, with the database name set to workforceos-leavemanagement-service.
Data deletion is managed using a soft delete strategy. Instead of removing records from the database, they are flagged as inactive by setting the isActive field to false.
| Object Name | Description | Public Access | Tenant Level |
|---|---|---|---|
leaveRequest |
Tracks employee leave/absence requests including period, type, status, reason, and approval state. Linked to a user and (optionally) department, with audit fields for request and approval. Company-tenant scoped. | accessProtected | Yes |
leaveRequest Data Object
Object Overview
Description: Tracks employee leave/absence requests including period, type, status, reason, and approval state. Linked to a user and (optionally) department, with audit fields for request and approval. Company-tenant scoped.
This object represents a core data structure within the service and acts as the blueprint for database interaction, API generation, and business logic enforcement.
It is defined using the ObjectSettings pattern, which governs its behavior, access control, caching strategy, and integration points with other systems such as Stripe and Redis.
Core Configuration
- Soft Delete: Enabled — Determines whether records are marked inactive (
isActive = false) instead of being physically deleted. - Public Access: accessProtected — If enabled, anonymous users may access this object’s data depending on API-level rules.
- Tenant-Level Scope: Yes — Enables data isolation per tenant by attaching a tenant ID field.
Properties Schema

- Required properties are mandatory for creating objects and must be provided in the request body if no default value is set.
- Properties marked
Type[] (array)MUST be sent as a JSON array (e.g.["a","b"]), even when only one value is present (["a"]). Sending a bare scalar fails validation.
Default Values
Default values are automatically assigned to properties when a new object is created, if no value is provided in the request body. Since default values are applied on db level, they should be literal values, not expressions.If you want to use expressions, you can use transposed parameters in any business API to set default values dynamically.
- userId: ‘00000000-0000-0000-0000-000000000000’
- requestDate: new Date()
- leaveType: ‘default’
- startDate: new Date()
- endDate: new Date()
- status: pending
- companyId: 00000000-0000-0000-0000-000000000000
Constant Properties
userId requestDate companyId
Constant properties are defined to be immutable after creation, meaning they cannot be updated or changed once set. They are typically used for properties that should remain constant throughout the object’s lifecycle.
A property is set to be constant if the Allow Update option is set to false.
Auto Update Properties
departmentId leaveType startDate endDate reason status approverId approvedDate
An update crud API created with the option Auto Params enabled will automatically update these properties with the provided values in the request body.
If you want to update any property in your own business logic not by user input, you can set the Allow Auto Update option to false.
These properties will be added to the update API’s body parameters and can be updated by the user if any value is provided in the request body.
Enum Properties
Enum properties are defined with a set of allowed values, ensuring that only valid options can be assigned to them. The enum options value will be stored as strings in the database, but when a data object is created an addtional property with the same name plus an idx suffix will be created, which will hold the index of the selected enum option. You can use the index property to sort by the enum value or when your enum options represent a sequence of values.
- status: [pending, approved, rejected, cancelled]
Elastic Search Indexing
userId departmentId requestDate leaveType startDate endDate reason status approverId approvedDate companyId
Properties that are indexed in Elastic Search will be searchable via the Elastic Search API. While all properties are stored in the elastic search index of the data object, only those marked for Elastic Search indexing will be available for search queries.
Database Indexing
userId departmentId status companyId
Properties that are indexed in the database will be optimized for query performance, allowing for faster data retrieval. Make a property indexed in the database if you want to use it frequently in query filters or sorting.
Secondary Key Properties
companyId
Secondary key properties are used to create an additional indexed identifiers for the data object, allowing for alternative access patterns. Different than normal indexed properties, secondary keys will act as primary keys and Mindbricks will provide automatic secondary key db utility functions to access the data object by the secondary key.
Relation Properties
userId departmentId approverId
Mindbricks supports relations between data objects, allowing you to define how objects are linked together. You can define relations in the data object properties, which will be used to create foreign key constraints in the database. For complex joins operations, Mindbricks supportsa BFF pattern, where you can view dynamic and static views based on Elastic Search Indexes. Use db level relations for simple one-to-one or one-to-many relationships, and use BFF views for complex joins that require multiple data objects to be joined together.
- userId: ID
Relation to
user.id
The target object is a sibling object, meaning that the relation is a many-to-one or one-to-one relationship from this object to the target.
On Delete: Set Null Required: Yes
- departmentId: ID
Relation to
userGroup.id
The target object is a sibling object, meaning that the relation is a many-to-one or one-to-one relationship from this object to the target.
On Delete: Set Null Required: No
- approverId: ID
Relation to
user.id
The target object is a sibling object, meaning that the relation is a many-to-one or one-to-one relationship from this object to the target.
On Delete: Set Null Required: No
Session-sourced Properties
userId
These properties have source: 'session' — their values are read from the authenticated session at create/update time and cannot be supplied in the request body.
- userId: ID property will be mapped to the session parameter
userId.
This property is the data object’s ownership field, used by ownership-based access control.
CustomData-sourced Properties
requestDate status
These properties have source: 'customData' — every create/update API on this data object declares the value via apiOptions.dataClauseSettings.customData[]. Refer to the per-API documentation for the concrete value each API writes.
Filter Properties
userId departmentId leaveType startDate endDate status companyId
Filter properties are used to define parameters that can be used in query filters, allowing for dynamic data retrieval based on user input or predefined criteria. These properties are automatically mapped as API parameters in the listing API’s that have “Auto Params” enabled.
-
userId: ID has a filter named
