ActionBlocks

ActionBlocks is a Ruby On Rails engine for building administrative database-driven applications.

• Automates Backend and Frontend Development

• Supports Granular Authorization

• Leverages PostgreSQL for Performance

• Encourages Task Oriented UI

Automates Backend and Frontend Development

A single low-code DSL is used to define both the backend and frontend.

ActionBlocks.app do
  title "My App"
  workspace :main do
    subspace :orders  do
      dashboard :all_orders do
        table :list_all do
          model :order
          columns [:number, :employee, :customer, :status]
        end
      end

...

Supports Granular Authorization

Row Level Security (RLS) is defined for each role.

ActionBlock.authorize Post do
    grant :reviewer do
        _or(
            _eq(:author_id, _user(:id)),
            _eq(:status, 'Published')
        ),
    end
end

Field Level Security (FLS) is defined for each role.

read do
    read :employee,          [:admin           ]
    read :customer,          [:admin, :customer]
    read :social_security    [:admin, :customer]
    read :order_date,        [:admin, :customer]
    read :shipped_date,      [:admin, :customer]
    read :ship_name,         [:admin, :customer]
    read :ship_address1,     [:admin, :customer]
    read :ship_address2,     [:admin, :customer]
    read :ship_city,         [:admin, :customer]
    read :ship_state,        [:admin, :customer]
    read :ship_postal_code,  [:admin, :customer]
    read :ship_country,      [:admin, :customer]
    read :shipping_fee,      [:admin, :customer]
    read :payment_type,      [:admin, :customer]
    read :paid_date,         [:admin, :customer]
    read :created_at,        [:admin, :customer]
    read :updated_at,        [:admin, :customer]
    read :region,            [:admin, :customer]
    read :referred_by,       [:admin, :customer]
end

Leverages PostgreSQL for Performance

ActionBlocks is similar to Hasura since it avoids N+1 queries and pushes JSON generation into PostgreSQL

• Uses an intelligent DSL managed data engine that avoids the N+1 problem associated with retrieving data in related tables and running authorization checks.

• Bypasses the performance tax of marshalling results to Objects and ultimately to JSON by pushing the transformation into PostgreSQL.

Encourages Task Oriented UI

Following the pholisophy of make the right thing the easy thing, ActionBlocks doesn't support CRUD. Instead it provides a rich DSL for Task Oriented UIs as explained https://cqrs.wordpress.com/documents/task-based-ui/
