    <p>For some reason I started to get this error after switching to Rails 3.2. I guess it has something to do with acl9 plugin, which I tried reinstalling, but nothing changed. </p> <p>I moved the plugins to lib/plugins and added initializer to config/initializers but again, same error. </p> <p>I looked for solution at acl9 repo on Github, but could not find anything there. Maybe it is not acl9 after all. </p> <p>I have paperclip, acl9, authlogic installed.</p> <pre><code>NoMethodError (undefined method `key?' for nil:NilClass): actionpack (3.2.1) lib/action_controller/metal/hide_actions.rb:36:in `visible_action?' actionpack (3.2.1) lib/action_controller/metal/hide_actions.rb:18:in `method_for_action' actionpack (3.2.1) lib/action_controller/metal/implicit_render.rb:14:in `method_for_action' actionpack (3.2.1) lib/action_controller/metal/compatibility.rb:61:in `method_for_action' actionpack (3.2.1) lib/abstract_controller/base.rb:115:in `process' actionpack (3.2.1) lib/abstract_controller/rendering.rb:45:in `process' actionpack (3.2.1) lib/action_controller/metal.rb:203:in `dispatch' actionpack (3.2.1) lib/action_controller/metal/rack_delegation.rb:14:in `dispatch' actionpack (3.2.1) lib/action_controller/metal.rb:246:in `block in action' actionpack (3.2.1) lib/action_dispatch/routing/route_set.rb:66:in `call' actionpack (3.2.1) lib/action_dispatch/routing/route_set.rb:66:in `dispatch' actionpack (3.2.1) lib/action_dispatch/routing/route_set.rb:30:in `call' journey (1.0.3) lib/journey/router.rb:68:in `block in call' journey (1.0.3) lib/journey/router.rb:56:in `each' journey (1.0.3) lib/journey/router.rb:56:in `call' actionpack (3.2.1) lib/action_dispatch/routing/route_set.rb:589:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/best_standards_support.rb:17:in `call' rack (1.4.1) lib/rack/etag.rb:23:in `call' rack (1.4.1) lib/rack/conditionalget.rb:25:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/head.rb:14:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/params_parser.rb:21:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/flash.rb:242:in `call' rack (1.4.1) lib/rack/session/abstract/id.rb:205:in `context' rack (1.4.1) lib/rack/session/abstract/id.rb:200:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/cookies.rb:338:in `call' activerecord (3.2.1) lib/active_record/query_cache.rb:64:in `call' activerecord (3.2.1) lib/active_record/connection_adapters/abstract/connection_pool.rb:443:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/callbacks.rb:28:in `block in call' activesupport (3.2.1) lib/active_support/callbacks.rb:405:in `_run__3140920687338355213__call__3168118505970967148__callbacks' activesupport (3.2.1) lib/active_support/callbacks.rb:405:in `__run_callback' activesupport (3.2.1) lib/active_support/callbacks.rb:385:in `_run_call_callbacks' activesupport (3.2.1) lib/active_support/callbacks.rb:81:in `run_callbacks' actionpack (3.2.1) lib/action_dispatch/middleware/callbacks.rb:27:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/reloader.rb:65:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/remote_ip.rb:31:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/debug_exceptions.rb:16:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/show_exceptions.rb:56:in `call' railties (3.2.1) lib/rails/rack/logger.rb:26:in `call_app' railties (3.2.1) lib/rails/rack/logger.rb:16:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/request_id.rb:22:in `call' rack (1.4.1) lib/rack/methodoverride.rb:21:in `call' rack (1.4.1) lib/rack/runtime.rb:17:in `call' activesupport (3.2.1) lib/active_support/cache/strategy/local_cache.rb:72:in `call' rack (1.4.1) lib/rack/lock.rb:15:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/static.rb:53:in `call' railties (3.2.1) lib/rails/engine.rb:479:in `call' railties (3.2.1) lib/rails/application.rb:220:in `call' rack (1.4.1) lib/rack/content_length.rb:14:in `call' railties (3.2.1) lib/rails/rack/log_tailer.rb:14:in `call' rack (1.4.1) lib/rack/handler/webrick.rb:59:in `service' /Users/project/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/webrick/httpserver.rb:138:in `service' /Users/project/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/webrick/httpserver.rb:94:in `run' /Users/project/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/webrick/server.rb:191:in `block in start_thread' </code></pre> <p>EDIT (SOLVED): It took quite a while to figure out and I am still not quite sure what happened. I think it has to do with acl9's support for Rails 3.1+ But in the end I took the acl9 code from github and everything suddenly started working. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
