Attribute Fields

A subset of attribute fields, such as required, optional, computed, or sensitive, define attribute behavior as boolean flags. Refer to Schemas - Attributes in the Framework documentation for details.

This page explains how to migrate the required, optional, computed, and sensitive attribute fields from SDKv2 to the Framework.

SDKv2

In SDKv2, Required, Optional, Computed, and Sensitive are boolean fields on the attribute's schema.

func resourceExample() *schema.Resource {
    return &schema.Resource{
         /* ... */
        Schema: map[string]*schema.Schema{
            "attribute_example": {
                Required:    bool
                Optional:    bool
                Computed:    bool
                Sensitive:   bool
                /* ... */

Framework

In the Framework, you set the same fields on the tfsdk.Attribute struct, with the same behavior.

func (d *resourceTypeExample) GetSchema(context.Context) (tfsdk.Schema, diag.Diagnostics) {
    return tfsdk.Schema{
        /* ... */
        Attributes: map[string]tfsdk.Attribute{
            "attribute_example": {
                Required:   bool
                Optional:   bool
                Computed:   bool
                Sensitive:  bool
                /* ... */

Example

The following examples show how to migrate portions of the http provider.

For a complete example, clone the terraform-provider-http repository and compare the data_source.go file in v2.2.0 and the data_source_http.go file after the migration.

SDKv2

The following example from the data_source.go file shows how the url attribute on the http data source is set to be required with SDKv2.

func dataSource() *schema.Resource {
    return &schema.Resource{
        Schema: map[string]*schema.Schema{
            "url": {
                Required:   true,
                /* ... */
            },
            /* ... */

Framework

The following example from the data_source_http.go file shows how the url attribute on the http data source is set to be required with the Framework.

func (d *httpDataSource) GetSchema(context.Context) (tfsdk.Schema, diag.Diagnostics) {
    return tfsdk.Schema{
        Attributes: map[string]tfsdk.Attribute{
            "url": {
                Required:   true,
                /* ... */
            },
            /* ... */
