Errors

Form / Field errors are calculate on each relevant action such as init, change value and change data. Errors is a result of both required and validators

This does not need to be passed by default in the initial form model json. You can pass it in the initial form model json, if you are currently loading a form model from persist model (i.e you saved the form model before user did page reload - and want to reload the form with the exact same model state that it was before the refresh)

Field Errors

model.fields.someField.errors - object array. Reflects field's errors. Field errors can contain required error, invalid errors (calculated from field.validators) or no errors at all.

Error object

Name	Type	Description
name	string	Validator name as appears in field.validators which represent a key in resources.validators
message	string	Result of message resource function as appears in resources.validators

Form Errors

model.errors - object. Reflects all errors in a form. Key is field id and value is its errors array as appears in field errors. Excluded fields are not included in this calculation.

Example

Create a component of errors summary that shows all form errors, and can read errors directly from model.errors.

model.errors = {
  email: [
    { name: 'email', message: 'Invalid email' },
  ]
  password: [
    { name: 'minLength', message: 'Minimum length is 2' },
    { name: 'includesOne', message: 'Value should include at least one of ["!", "@", "#", "$", "%", "^", "&", "*"]' },
    { name: 'includesOne', message: 'Value should include at least one of ["1", "2", "3", "4", "5", "6", "7", "8", "9", "0"]' },
  ]
};
