Notes

You can use Current Application, Current User, and Current Form Data variables in expressions

Dynamic Value

Use Expression as Default Value

If you need to dynamically set the default value for fields in the form when creating, you can use the Dynamic Default Value Expression setting.

Example Usage

For example, when submitting a leave application, the applicant's department needs to be set to the department of the current submitter, and expressions can be used to query the current user's department.

Set Field Value When Other Form Fields Change

Field linkage is to set the value of this field when other fields in the form change.

Example Usage

For example, after the user selects a product on the order page, the Product Price field needs to be automatically set to the Price of the Product table.

Notes

Note that the type returned by the Value Expression must be consistent with the storage type of the field. Inconsistent data types will cause errors.

• Dependent Field refers to which field triggers the rule when it changes.
• Value Expression refers to the value set for this field after the rule is triggered.

Validation

Set as Required When Expression is Satisfied

Override the required control of the field through an expression. If not filled in, the required control set by the field is used by default. The expression returns a boolean type.

Field Validation Rules

Check whether the field meets the business rules when the form is submitted. The field validation rules consist of two parts.

• Expression The expression returns a boolean type. If it returns false, it means the condition is not met, the user is not allowed to submit, and a prompt message is displayed
• Prompt Message When Condition Not Met The prompt message when the expression returns false.

Form validation will only be triggered in the following scenarios:

• Web form filling
• Workflow form submission
• Questionnaire submission

Example Usage

For example, when submitting an order, it is necessary to determine that the purchase quantity amount must be greater than 10, then the expression needs to be set to

${record.amount>10}

Notes

When multiple rules are set, all rules need to be satisfied to pass the validation

Change Record

The change record mainly controls whether to record a change log when the field content in the data table record changes.

Notes

After enabling the Field Change Log Function of the data table to which the field belongs, when modifying data table records through Forms and Workflows, if the modified field has enabled Record Change Log When Modified, the value before modification and the value after modification will be recorded in the change record table. The format of the change record table is shown in Change Record Table

Configuration Item	Description
Record Change Log When Modified	Not enabled by default. After enabling, when the field content changes, the system will automatically record the change log
Allow the Following Roles to View Change Records of This Field	By default, all users can view. After configuration, only the configured roles can view

Notes

• Field Required

  If the field is hidden or read-only, it will not participate in the required validation when submitting data.

• Dynamic Validation

  Dynamic validation is checked by the server, and it will only be validated after the user submits the data.
