GYM Management System

1. Project Overview

The CultFit Gym Management System is built on the Salesforce platform using Apex triggers and custom objects.
It automates the process of onboarding new members by:

Creating Member records.

Automatically assigning a default trainer when a new member joins.

Creating a Session record scheduled for the next day.

Setting the session status to Schedule without manual work.

2. Objects and Fields

Field Label	API Name	Data Type	Description
Member Name	Name	Text	The full name of the member.
Mobile Number	Mobile__c	Text	The member’s mobile phone number for contact purposes.
Email	Email__c	Email	The member’s email address, used for communication or notifications.
Join Date	Join_Date__c	Date	The date when the member joined or registered in the system.

Trainer Object (Trainer__c)

Field Label	API Name	Data Type	Description
Trainer Name	Name	Text	The full name of the trainer.
Specialization	Specialization__c	Picklist	The trainer’s area of expertise (e.g., Yoga, Swimming, Fitness, Cooking, etc.).

Session Object (Session__c)

Field Label	API Name	Data Type	Description
Session Number	Name	Auto Number	A system-generated unique number assigned to each session record.
Member	Member__c	Lookup	Lookup to Member__c, linking the session to the participating member.
Trainer	Trainer__c	Lookup	Lookup to Trainer__c, linking the session to the assigned trainer.
Date	Date__c	Date	The scheduled date of the session.
Status	Status__c	Picklist	The current status of the session (Scheduled, Completed, or Cancelled).

3. Business Logic Implemented

Assign Default Trainer: When a new member is added, the system automatically assigns the first available trainer.

Create Session: A session is created for the next day with Status = “Scheduled”.

4. Apex Trigger

This trigger runs on the Member__c object and executes after insert.

 Go to Setup

Click the ⚙️ Gear icon (top-right corner).

Select Setup.

 Search for Apex Triggers

In the Quick Find search bar, type Apex Triggers.

Click on Apex Triggers under Custom Code.

 Click New

On the Apex Triggers page, click the New button.

 Select the Object

From the dropdown, select Member__c (because the trigger runs on this object).

 Enter Trigger Name and Events

Trigger Name: AssignDefaultTrainer

Object: Member__c

Events: choose after insert (since it should run after a member record is created).

 Write the Trigger Code

Copy-paste the trigger code into the editor:

AssignDefaultTrainer.trigger

trigger AssignDefaultTrainer on Member__c (after insert) {

List<Trainer__c> trainers = [SELECT Id FROM Trainer__c LIMIT 1];

if (!trainers.isEmpty()) {

List<Session__c> sessionsToInsert = new List<Session__c>();

for (Member__c mem : Trigger.new) {

Session__c ses = new Session__c();

ses.Member__c = mem.Id;

ses.Trainer__c = trainers[0].Id;

ses.Date__c = Date.today().addDays(1);

ses.Status__c = ‘Scheduled’;

sessionsToInsert.add(ses);

}

insert sessionsToInsert;

}

 Click Save

If there are no syntax errors, Salesforce will save the trigger successfully.

 Test the Trigger

Create a new Member__c record.

After saving, check Session__c records → You should see a new session created automatically:

Linked to the Member

Assigned to the Trainer (first one found)

Date = Tomorrow

Status = “Scheduled”

Explanation:

Query Trainer: Fetch the first available trainer.

Loop through Members: For every new member, create a session.

Set Values: Assign Member, Trainer, Date = Tomorrow, Status = Scheduled.

Bulk Insert: Insert all session records in a single DML operation.

5. Test Class

AssignDefaultTrainerTest

@isTest

public class AssignDefaultTrainerTest {

@isTest

static void testAssignDefaultTrainer() {

// Create a Trainer record

Trainer__c trainer = new Trainer__c(Name = ‘John Trainer’, Specialization__c = ‘Fitness’);

insert trainer;

// Create a Member record

Member__c member = new Member__c(Name = ‘Test Member’, Mobile__c = ‘9876543210’, Email__c = ‘test@test.com’);

insert member;

// Fetch the created session

Session__c session = [SELECT Member__c, Trainer__c, Date__c, Status__c FROM Session__c WHERE Member__c = :member.Id LIMIT 1];

// Validate Session Details

System.assertEquals(member.Id, session.Member__c, ‘Member should match’);

System.assertEquals(trainer.Id, session.Trainer__c, ‘Trainer should match’);

System.assertEquals(‘Scheduled’, session.Status__c, ‘Status should be Scheduled’);

System.assertEquals(Date.today().addDays(1), session.Date__c, ‘Date should be tomorrow’);

}

Explanation of Test Class

1. @isTest → Marks this class as a test class.

2. Creates a Trainer record.

3. Creates a member record → triggers AssignDefaultTrainer logic.

4. Queries the Session created automatically.

5. Validates:

Member linked correctly.

Trainer assigned.

Status = Scheduled.

Date = Tomorrow.

This ensures that the trigger works properly and is 100% covered.

6. Key Features

Automatically assigns a default trainer when a new member joins.

Creates a session for the next day without manual input.

Ensures data consistency and automation using Apex triggers.

Fully tested with a unit test class for deployment.

7. Conclusion

The FitPro Gym Management System simplifies and automates the onboarding process for gym members by leveraging Salesforce Apex triggers.
With this solution:

Trainers are automatically assigned to new members.

Initial sessions are scheduled for the next day without manual effort.

The process ensures accuracy, consistency, and time savings for gym staff.

This project demonstrates how Salesforce automation can be effectively used to manage real-world business scenarios like gym membership and session scheduling. It can be further enhanced by:

Round-robin trainer allocation for fair distribution.

Specialization-based assignment to match member goals.

Notifications and reminders for members and trainers.
