I’m interested in creating dynamic calculation rules in Angular that can be stored in a database for future use. These rules will be applied to employee data to calculate various dynamic fields defined by the user.
Dynamic fields:
Basic Salary
OT Hours 1
OT Value 1
OT Hours 2
OT Value 2
OT Amount 1
OT Amount 2
Loan
Salary Advance
Gross Salary
Total Deduction
Net Salary
The dynamic fields that will be involved in the calculations.
Calculation rules:
[
{field: 'Basic Salary',
expression: 'number',
isCalculate: false},
{field: 'OT Hours 1',
expression: 'number',
isCalculate: false},
{field: 'OT Hours 2',
expression: 'number',
isCalculate: false},
{field: 'OT Value 1',
expression: '((Basic Salary / 26)/8)*1.5',
isCalculate: true},
{field: 'OT Value 2',
expression: '((Basic Salary / 26)/8)*2',
isCalculate: true},
{field: 'OT Amount 1',
expression: 'OT Hours 1 * OT Value 1',
isCalculate: true},
{field: 'OT Amount 2',
expression: 'OT Hours 2 * OT Value 2',
isCalculate: true},
{field: 'Loan',
expression: 'number',
isCalculate: false},
{field: 'Salary Advance',
expression: 'number',
isCalculate: false},
{field: 'Gross Salary',
expression: 'Basic Salary + OT Amount 1 + OT Amount 2',
isCalculate: true},
{field: 'Total Deduction',
expression: 'Loan + Salary Advance',
isCalculate: true},
{field: 'Net Salary',
expression: 'Gross Salary - Total Deduction',
isCalculate: true},
]
The calculation rules will be represented as an array of objects. Each object will contain the field name, the calculation expression, and a flag to indicate whether the field needs to be calculated or not.
Later, when a user wants to calculate Salary for employees, the system will evaluate these expressions based on the provided input data and return the results.
Is there an effective way to achieve this functionality in Angular? Any advice or guidance would be greatly appreciated.
