class Marten::Handlers::RecordDetail

Overview

Handler allowing to display a specific model record.

This handler can be used to showcase a specific model record. It is expected that the handler will be accessed through a GET request only: as part of this request, the configured template is rendered and displayed (and the retrieved model record is inserted into the template context)

class MyRecordHandler < Marten::Handlers::RecordDetail
  model MyModel
  template_name "my_record.html"
end

The model class used to retrieve the record can be configured through the use of the #model macro. The #template_name class method allows to define the name of the template to use to render the model record.
