Removed ORM-specific branches from admin generator helpers (orm.rb, actions.rb, admin_app.rb)
Removed DataMapper IdentityMap middleware insertion from admin generator
Updated admin template index pages to reflect supported ORMs
Removed all related tests, updated generic tests to use sequel instead
Updated README ORM listing and removed stale DM rake task references

Remaining supported ORMs: ActiveRecord, MiniRecord, Mongoid, Sequel, Ohm, Mongomatic, Dynamoid

The admin landing page tooltip lists supported ORMs, but it omits ohm and dynamoid, which are still supported by the admin generator. Update the title text to include all supported adapters (or make it generic) to avoid misleading users.

Suggested change

div class="btn btn-primary" title="Adapters for sequel, activerecord, minirecord, mongoid" = tag_icon("cogs fa-2x", "Orm Agnostic")

div class="btn btn-primary" title="Adapters for sequel, activerecord, minirecord, mongoid, ohm, dynamoid" = tag_icon("cogs fa-2x", "Orm Agnostic")

+    .btn.btn-primary{title: 'Adapters for sequel, activerecord, minirecord, mongoid'}


The tooltip text here lists supported ORMs but does not include ohm and dynamoid, which are in the current supported ORM list for the admin generator. Please update the list (or reword to avoid enumerating adapters) so the UI text stays accurate.

Suggested change

.btn.btn-primary{title: 'Adapters for sequel, activerecord, minirecord, mongoid'}

.btn.btn-primary{title: 'Adapters for multiple ORMs and data stores'}

This tooltip enumerates supported ORMs but omits ohm and dynamoid, which are still supported by the admin generator. Update the title attribute to reflect the full supported set (or avoid hard-coding a list) so users aren’t misled.

Suggested change

<div class="btn btn-primary" title="Adapters for sequel, activerecord, minirecord, mongoid"><%%= tag_icon("cogs fa-2x", "Orm Agnostic") %></div>

+Orm Agnostic:: Data Adapters for Activerecord, Sequel, Mongoid, Ohm, Dynamoid
 Template Agnostic:: Erb, Erubis and Haml Renderer
 Authentication:: Support for Account authentication, Account Permission management
 Scaffold:: You can simply create a new "admin interface" by providing a Model


This ORM list is missing MiniRecord, which is still supported by the admin generator. Also, further down this README still references DataMapper-specific rake tasks (e.g., dm:migrate, dm:auto:migrate); those instructions should be updated/removed now that DataMapper support is being removed.

Copilot · 2026-03-29T22:57:45Z

 mock::       none  (default), mocha, rr
 script::     none  (default), jquery, prototype, mootools, extcore, dojo
-orm::        none  (default), datamapper, mongomapper, mongoid, activerecord, minirecord, sequel, couchrest, ohm, mongomatic, ripple, dynamoid
+orm::        none  (default), mongoid, activerecord, minirecord, sequel, ohm, mongomatic, dynamoid


The PR description lists the “remaining supported ORMs” but doesn’t mention mongomatic, while this README still documents mongomatic as supported (and the generator still exists). Please align the PR description and documentation: either include mongomatic in the supported list or remove/flag its generator support.

Tested locally on Ruby 3.3.1 — all 1,412 tests pass (5,236 assertions, 0 failures) across all 9 sub-gems.

Reviewed the full diff (26 files, +29/-1011 lines). Clean removal — no remaining references to the 4 removed ORMs in any .rb source files. Tests properly updated to use Sequel where they previously used DataMapper/CouchRest.

Minor note (non-blocking, pre-existing): mongomatic is still listed as a supported ORM in padrino-gen's README but has no admin account template and isn't in the admin's supported_orm list. This predates this PR — just flagging for awareness since it might be a candidate for the same treatment.

Otherwise, LGTM ✅ Merging
