Assignment: Developing Service

This assignment tests your ability to:

  1. Discuss the service type entity-auto:

    • Is the name of the entity you defined in Moqui the same as the entity name in MySQL?
    • What did you observe, and why?
    • If MySQL works with SQL but you did not write SQL, does this mean MySQL with Moqui doesn’t require SQL?
    • Discuss differences between ORM and JDBC (Reference).

  2. Explain Groovy:

    • How is it similar to and different from Java?

  3. Explore APIs:

    • What is a RESTful API?
    • What is JsonRPC, and how does it differ from REST APIs?

Tasks

Task 1: Create an Entity-Auto Service

  • Goal: Generate records in the MoquiTraining entity automatically.
  • Steps:
    • Use entity-auto service type.
    • Define input parameters for all non-primary key fields of MoquiTraining.
    • Include validations:
      • trainingName is mandatory.
      • trainingDate must follow MM/dd/yyyy format.
    • Ensure the service returns the trainingId.

Task 2: Implement Services

  • Default Type: Create a service with the default type to generate MoquiTraining records.
  • Groovy Script: Write a Groovy service for logic and data creation.

Task 3: Prepare Data File

  • CSV File: Create a CSV file to input data into the entity.

Task 4: Load and Verify Data

  • Load Data: Populate the entity from the CSV file using Gradle tasks or equivalent.
  • Verify:
    • Check if records are created in the database.
    • Test services directly via Moqui UI or API calls.

Submission Instructions

  • Commit and push the service implementations and CSV file to the moqui-training repository on GitHub.

Tutorial

Moqui services are the backbone of application logic, enabling data management, updates, and workflows.

  2. Moqui Training Video 4

Key Concepts

  • Execution Context: Provides a runtime environment for Moqui artifacts and framework tools.
  • Service Definition: Specifies the service name, parameters, and attributes.
  • Service Implementation: Contains service logic written in Groovy or Java.
  • Service Invocation: Call services from other services, screens, or scripts.

Entity-Auto Services

Entity-auto services simplify operations like create, update, and delete.

Validation and Testing

  • Input validation ensures data integrity.
  • Test rigorously to meet functional and performance requirements.
