Radio

The Radio field is used to render radio buttons. It's useful when only one value can be selected in a given options group.

Field declaration example

Below is an example of declaring a radio field for a role:

field :role,
  as: :radio,
  name: "User role",
  options: {
    admin: "Administrator",
    manager: "Manager",
    writer: "Writer"
  }

-> options

The options attribute accepts either a Hash or a proc, allowing the incorporation of custom logic. Within this block, you gain access to all attributes of Avo::ExecutionContext along with the record, resource, view and field.

This attribute represents the options that should be displayed in the radio buttons.

Default value

Empty Hash.

{}

Possible values

Any Hash. The keys represent the value that will be persisted and the values are the visible labels. Example:

options: {
  admin: "Administrator",
  manager: "Manager",
  writer: "Writer"
}

Or a Proc:

options: -> do
  record.roles.each_with_object({}) do |role, hash|
    hash[role.id] = role.name.humanize
  end
end
