Service Design Specification - Object Design for planMeal

aifitapp-aicoach-service documentation

Document Overview

This document outlines the object design for the planMeal model in our application. It includes details about the model’s attributes, relationships, and any specific validation or business logic that applies.

planMeal Data Object

Object Overview

Description: Individual meals within a meal plan with food details and macro breakdown. Created and modified exclusively by AI tool calls.

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

Properties Schema

Display Label Property: mealLabel — This property is the default display label for records of this data object. Relation dropdowns and record references in the frontend will show the value of this property as the human-readable label.

Property Type Required Description
carbs Float Yes Carb grams for this meal
fat Float Yes Fat grams for this meal
foods Text Yes Food items and quantities description
mealLabel String Yes Meal label (e.g. breakfast, lunch, dinner, snack)
mealPlanId ID Yes Reference to the parent meal plan
protein Float Yes Protein grams for this meal
sortOrder Integer Yes Display sort order within the meal plan
totalCalories Integer Yes Total calories for this meal

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.

Constant Properties

mealPlanId

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

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.

Elastic Search Indexing

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

mealPlanId

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.

Relation Properties

mealPlanId

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.

The target object is a parent object, meaning that the relation is a one-to-many relationship from target to this object.

On Delete: Set Null Required: Yes

Filter Properties

mealPlanId

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.
