Update in place handle situation

Terraform Providers
1

Hello

I have the situation when refreshing plan there is field which I don’t update from schema.
And when update function is called there are created empty request and because it’s failed.

2021/01/15 13:20:22 [DEBUG] UserGroup update configuration: &testgo.UserGroupEditRequest{Label:"", RoleIDs:[]string(nil), BillingPlanIDs:[]int(nil)}

How I can skip calling update function if some fields are updated in place???

Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform will perform the following actions:

  # module.ug["tf_ug"].user_group.ug will be updated in-place
  ~ resource "user_group" "ug" {
        label              = "tf_ug"
        preconfigured_only = false
        provider_vdc_id    = 0
      + roles              = (known after apply)
        updated_at         = "2021-01-15T11:52:43.000Z"

			"roles": {
				Type:     schema.TypeList,
				Computed: true,
				Elem: &schema.Resource{
					Schema: datasourceRoleSchema(),
				},
			},

func resourceUserGroupUpdate(d *schema.ResourceData, meta interface{}) error {
	client := meta.(*CombinedConfig).testgoClient()
	if client == nil {
		return fmt.Errorf("[ERROR] testgoClient return nil")
	}

	id, err := strconv.Atoi(d.Id())
	if err != nil {
		return fmt.Errorf("invalid user group id: %v", err)
	}

	opts := &testgo.UserGroupEditRequest{}

	// Enable partial state mode
	d.Partial(true)

	if d.HasChange("label") {
		opts.Label = d.Get("label").(string)
	}
	if d.HasChange("role_ids") {
		if attr, ok := d.GetOk("role_ids"); ok {
			opts.RoleIDs = expandSliceOfString(attr.(*schema.Set).List())
		}
	}
	if d.HasChange("billing_plan_ids") {
		if attr, ok := d.GetOk("billing_plan_ids"); ok {
			opts.BillingPlanIDs = expandBillingPlanIDs(attr.([]interface{}))
		}
	}

	d.Partial(false)

	log.Printf("[DEBUG] UserGroup update configuration: %#v", opts)

	_, err = client.UserGroups.Edit(context.Background(), id, opts)
	if err != nil {
		return fmt.Errorf("[ERROR] Error updating UserGroup: %s", err)
	}

	return resourceUserGroupRead(d, meta)
}

Hey, guys no idea?

Okay,
To avoid sending empty POST request during update I rewrite my update function:

	if d.HasChange("label") || d.HasChange("role_ids") || d.HasChange("billing_plan_ids") {
		opts := &testgo.UserGroupEditRequest{}

		opts.Label = d.Get("label").(string)

		if attr, ok := d.GetOk("role_ids"); ok {
			opts.RoleIDs = expandSliceOfString(attr.(*schema.Set).List())
		}

		if attr, ok := d.GetOk("billing_plan_ids"); ok {
			opts.BillingPlanIDs = expandBillingPlanIDs(attr.([]interface{}))
		}

		log.Printf("[DEBUG] UserGroup update configuration: %#v", opts)

		_, err = client.UserGroups.Edit(context.Background(), id, opts)
		if err != nil {
			return fmt.Errorf("[ERROR] Error updating UserGroup: %s", err)
		}
	}

but I don’t like next construction:

if d.HasChange("label") || d.HasChange("role_ids") || d.HasChange("billing_plan_ids") {

So there is some other methods to check difference between many fields in schema, or how I can get all changed fields to build update POST request?
