Select ​

A Hash representing the options that should be displayed in the select. The keys represent the labels, and the values represent the value stored in the database.

The options get cast as ActiveSupport::HashWithIndifferentAccess objects if they are a Hash.

Default ​

nil

Possible values ​

{ 'Large container': :large, 'Medium container': :medium, 'Tiny container': :tiny } or any other Hash.

Set the select options as an Active Record enum. You may use options or enum, not both.

# app/models/project.rb
class Project < ApplicationRecord
  enum type: { 'Large container': 'large', 'Medium container': 'medium', 'Tiny container': 'small' }
end

# app/avo/resources/project.rb
class Avo::Resources::Project < Avo::BaseResource
  field :type,
    as: :select,
    enum: ::Project.types,
    display_with_value: true,
    placeholder: 'Choose the type of the container.'
end

Default ​

nil

Possible values ​

Post::statuses or any other enum stored on a model.

You may want to display the values from the database and not the labels of the options. You may change that by setting display_value to true.

# app/avo/resources/project.rb
class Avo::Resources::Project < Avo::BaseResource
  field :type,
    as: :select,
    display_with_value: true
end

Default ​

false

Possible values ​

true, false

Include blank ​

The Select field also has the include_blank option. That can have three values.

If it's set to false (default), it will not show any blank option but only the options you configured.

If it's set to true and you have a placeholder value assigned, it will use that placeholder string as the first option.

If it's a string include_blank: "No country", the No country string will appear as the first option in the <select> and will set the value empty or nil depending on your settings.

# app/avo/resources/project.rb
class Avo::Resources::Project < Avo::BaseResource
  field :type,
    as: :select,
    include_blank: 'No type'
end

Default ​

nil

Possible values ​

nil, true, false, or a string to be used as the first option.
