Administrate::Field::Jsonb

A plugin to show and edit JSON objects within Administrate. inspired by Administrate::Field::JSON.

This gem uses jsoneditor.

Installation

Add this line to your application's Gemfile:

gem 'administrate-field-jsonb'

And then execute:

bundle

If you are using asset pipeline, add the following lines to your manifest.js:

//= link administrate-field-jsonb/application.css
//= link administrate-field-jsonb/application.js

The manifest file is at app/assets/config by default.

Usage

ATTRIBUTE_TYPES = {
  # ...
  details: Field::JSONB
}.freeze

If you have some kind of serialization, you can call methods on your object with transform option.

ATTRIBUTE_TYPES = {
  # ...
  details: Field::JSONB.with_options(
    transform: %w[to_h symbolize_keys]
  )
}.freeze

It also supports Proc.

ATTRIBUTE_TYPES = {
  # ...
  details: Field::JSONB.with_options(
    transform: [:transformation, Proc.new { |item| item.merge({ foo: 'bar' }) }]
  )
}.freeze

And there is a built in parse_json option, it will call JSON.parse(your_object) on your object.

ATTRIBUTE_TYPES = {
  # ...
  details: Field::JSONB.with_options(
    transform: [:parse_json, :some_other_stuff]
  )
}.freeze

If you want to edit json displaying on show page, you can use advanced_view option (both JSON and arrays are supported).

ATTRIBUTE_TYPES = {
  # ...
  details: Field::JSONB.with_options(transform: %i[to_h symbolize_keys], advanced_view: {
    company:  Field::String,
    position: Field::String,
    skills: Field::JSONB.with_options(advanced_view: {
      'name'  => Field::String,
      'years' => Field::Number.with_options(suffix: ' years')
    })
  }),
  languages: Field::JSONB.with_options(advanced_view: {
    'title' => Field::String,
    'code'  => Field::String,
  })
}.freeze

NOTE: don't define advanced_view option if you want to display JSON with the jsoneditor.

To customize what to display if you have an empty value, use blank_sign option, by default it's -.

ATTRIBUTE_TYPES = {
  # ...
  details: Field::JSONB.with_options(
    blank_sign: 'oops, missed'
  )
}.freeze

Recipes

If you want to store your JSON in hash format and not a string add this to your model.

def your_field_name=(value)
  self[:your_field_name] = value.is_a?(String) ? JSON.parse(value) : value
end

Example:

def details=(value)
  self[:details] = value.is_a?(String) ? JSON.parse(value) : value
end

If you don't see details in advanced_view, try to add this

transform: %i[to_h symbolize_keys]

or use string keys.

languages: Field::JSONB.with_options(advanced_view: {
  'title' => Field::String,
  'code'  => Field::String,
})
