Overview

Documents in the host's own database, through a model class the host supplies, optionally scoped (per session, per tenant). Not auto-required; load it with require "mistri/workspace/active_record".

The model needs a path column and a content column, unique on path within the scope. A migration to copy:

create_table :mistri_documents do |t|
t.string :session_id, null: false
t.string :path, null: false, limit: 512
t.text :content, size: :medium, null: false
t.timestamps
end
add_index :mistri_documents, [:session_id, :path], unique: true
