Upgrade to v3

Breaking changes

Cors configuration

Set CORS credentials: true if you're using custom CORS configuration. See how to configure CORS headers.

We use the Rack CORS Gem for this purpose.

Gemfile
# Gemfile
source 'https://rubygems.org'

# ...

gem 'forest_liana'
gem 'rack-cors'
/config/application.rb
module LiveDemoRails
  class Application < Rails::Application
    # ...

    # For Rails 5, use the class Rack::Cors. For Rails 4, you MUST use the string 'Rack::Cors'.
    config.middleware.insert_before 0, Rack::Cors do
      allow do
        origins 'app.forestadmin.com'
        resource '*',
          headers: :any,
          methods: :any,
          expose: ['Content-Disposition'],
          credentials: true
      end
    end
  end
end

Global smart action

Smart actions defined as follows global: true will no longer be considered as global.

Please now use type: 'global'.

Before

lib/forest_liana/collections/product.rb
class Forest::Product
  include ForestLiana::Collection

  collection :Product

  action 'Import data',
    global: true

  # ...
end

After

lib/forest_liana/collections/product.rb
class Forest::Product
  include ForestLiana::Collection

  collection :Product

  action 'Import data',
    type: 'global'

  # ...
end

Schema versioning

On server start - only in development environments - the agent will generate a .forestadmin-schema.json file reflecting your Forest Admin schema.

If you change your models or database, Forest Admin will automatically load a new schema to keep the layout up to date.

Version this file. It will give you more visibility on the changes detected by Forest Admin.

In the following example, we have added two fields on the invoices table:

  • emailSent

  • quadernoId

Versioning the.forestadmin-schema.json file allows you to easily visualize the changes.
