Percent

Introduction

In NocoBase, the Percent field stores percentage values.

It is suitable for completion rates, discount rates, conversion rates, and other ratios. Use Number when the business value is not a percentage.

Use cases

Percent fields are suitable for these business scenarios:

Task completion rates
Discount and tax rates
Conversion and pass rates
Progress and utilization rates

Create and configure

On the collection's Configure fields page, click Add field and select Percent to create this field.

Configure a Percent field

Setting	Description
Field interface	The field interface. Percent uses `percent`, which determines how the field is entered and displayed in pages.
Field display name	The name displayed for the field, such as `Completion rate`, `Discount rate`, or `Conversion rate`. Use a name that business users can recognize.
Field name	The field identifier used internally by APIs, relation fields, permissions, and workflows. It usually cannot be changed after creation. It supports only letters, numbers, and underscores, and must begin with a letter.
Field type	The data-layer type. Percent uses `double` by default.
Default value	The default value. When a new record has no value, NocoBase can fill this value automatically.
Validation rules	Validation rules. Supports minimum, maximum, and required validation.
Description	A field description. Record the field meaning, entry requirements, data source, or maintainer.

Note

Field names are referenced by page blocks, permissions, workflows, and APIs after creation. Confirm the name before creating the field to avoid later configuration changes.

Field behavior

The default behavior of a Percent field is as follows:

Behavior	Description
Default Field interface	`percent`.
Default Field type	`double`.
Available Field types	`double`, `decimal`.
Page component	Uses a percentage-aware number input in edit mode.
Filtering	Supports numerical filters such as greater than, less than, equals, and is empty.
Sorting	Supports sorting in Table blocks.
Validation	Supports minimum, maximum, and required validation.

Edit configuration

After creation, click Edit beside the field to edit its configuration. Edit fields to adjust how they are displayed and used in NocoBase, such as the display name, description, default value, validation rules, or field-specific settings.

When a field comes from a synchronized main-database table, editing usually maps the database field to a NocoBase Field type and Field interface.

Setting	Can be edited	Description
Field display name	Yes	Changes the name displayed in the interface without changing the field identifier.
Field name	No	The field identifier normally cannot be changed in the edit form after creation.
Field interface	Conditional	Main-database fields and synchronized fields can be adjusted during field mapping. Changes affect page input, display, and validation.
Field type	Conditional	Main-database fields and synchronized fields can be adjusted during field mapping. Confirm that existing values can be used by the new type first.
Default value	Yes	Adjusts the default value for new records.
Validation rules	Yes	Adjusts field validation rules.
Description	Yes	Adds the field meaning, entry requirements, data source, or maintainer.

Note

Changing a Field type or Field interface is more than changing a display name. It affects field storage, input components, validation rules, filters, and workflow-variable usage. When the field contains substantial existing data, confirm that its data format is compatible first.

Delete field

Click Delete beside a Percent field to delete it. You can also select multiple fields and delete them in the main data source.

Deleting a Percent field created in the main database usually also deletes the actual database column and its values. For a synchronized or external-data-source field, the impact depends on the corresponding data source and field origin.

Warning

Deleting a field can affect page blocks, forms, filters, permissions, workflows, APIs, imports and exports, and existing data. Confirm that the field is no longer referenced by business configuration before deleting it.

Use in pages

Percent fields are suitable for percentage entry, display, statistics, and conditions.

Use a Percent field in a page

Scenario	Use
Form block	Enter a percentage value.
Table block	Display, sort, and filter percentages.
Details block	Display a percentage value.
Workflows and permissions	Use the value in percentage conditions and calculations.
