Lack of Explicit Custom Validation on Properties/Fields

[danieljancar]

Description

Hello everyone,
While FireCMS provides the ability to create custom fields by passing a React component to the fieldConfig prop, it lacks explicit documentation or features for adding custom validation logic to these fields. Correct me if im wrong. 😄

Example

Consider a scenario where we have a role field and an age field in the schema. The role field should only accept numbers that are multiples of 3, and the age field should only accept numbers between 18 and 60, inclusive.

role: {
    title: 'Role',
    dataType: 'number',
    validation: {required: true},
    // Hypothetical custom validation
    customValidation: (value) => {
        if (value % 3 !== 0) {
            return "Role number must be a multiple of 3";
        }
        return null;
    },
},
age: {
    title: 'Age',
    dataType: 'number',
    validation: {required: true},
    // Hypothetical custom validation
    customValidation: (value) => {
        if (value < 18 || value > 60) {
            return "Age must be between 18 and 60";
        }
        return null;
    },
},

Suggested Solution

Introduce a customValidation function property to the field definition, allowing developers to specify custom validation logic. This function could return a string to indicate a validation error or null if the value is valid.

Thank you for your feedback.

Hey @fgatti675,
Could I help implementing this feature or is it already worked on? 😄
