Module: Compony::ComponentMixins::Resourceful

Extended by:
ActiveSupport::Concern
Included in:
Compony::Components::Destroy, Compony::Components::Edit, Compony::Components::New
Defined in:
lib/compony/component_mixins/resourceful.rb

Overview

Include this when your component's family name corresponds to the pluralized Rails model name the component's family is responsible for. When including this, the component gets an attribute @data which contains a record or a collection of records. Resourceful components are always aware of a data_class, corresponding to the expected @data.class and used e.g. to render lists or for .new.

Instance Method Details

#after_assign_attributes(&block) ⇒ Object (protected)

DSL method Runs after assign_attributes and before store_data for all standalone paths and verbs. Example use case: prefilling some fields for a form

  @global_after_assign_attributes_block = block
end

#after_load_data(&block) ⇒ Object (protected)

DSL method Runs after loading data and before authorization for all standalone paths and verbs. Example use case: if load_data produced an AR collection proxy, can still refine result here before to_sql is called.

end

#assign_attributes(&block) ⇒ Object (protected)

DSL method Sets a default default assign_attributes block for all standalone paths and verbs. Can be overwritten for a specific path and verb in the Default::Standalone::VerbDsl. The block is expected to assign suitable params to attributes of @data.
