Error message

<= At the moment, Padrino only supports #{supported_orm.join(' or ')}. Sorry!

What it means

The admin generator (padrino-gen admin) aborts unless the project's ORM component is one of minirecord, activerecord, mongoid, sequel, ohm or dynamoid (Padrino::Generators::Admin::Actions#supported_orm). It prints this yellow notice with say and then raises SystemExit, so nothing is generated. Notably DataMapper — supported by older Padrino versions — is rejected here.

Solutions

1. Edit .components at the project root and switch the orm line to a supported value (activerecord is the safest), then re-run `padrino g admin`
2. Fix typos — the value must be exactly one of minirecord/activerecord/mongoid/sequel/ohm/dynamoid
3. If you must keep the unsupported ORM, build the admin section by hand or use another admin layer — this generator cannot emit code for it

Example fix

# .components before
orm: datamapper

# .components after
orm: activerecord
# then: bundle exec padrino g admin

supported = %i[minirecord activerecord mongoid sequel ohm dynamoid]
choice = File.read('.components')[/^orm:\s*(.+)/, 1].to_s.strip.to_sym
abort "unsupported orm #{choice}; admin needs one of #{supported.join('/')}" unless supported.include?(choice)

def admin_supported_orm?(orm) = %i[minirecord activerecord mongoid sequel ohm dynamoid].include?(orm.to_sym)

begin
  Padrino::Generators::AdminApp.start([])
rescue SystemExit
  # generator printed the yellow notice and aborted; fix .components first
end

When it happens

Trigger: Running `padrino g admin` in an app whose .components selects an unsupported orm (datamapper, or a typo like datamaper); generating the project with `padrino-gen project myapp -d datamapper` and then asking for an admin section.

Common situations: Upgrading a legacy DataMapper app to a Padrino version that dropped admin support for it; hand-edited .components with a typo; choosing an ORM the project generator offers but the admin generator does not.
