Created a new model ‘klasse’ using scaffold, which was pluralised to  
‘klasses’, which I don’t want!  
Removed all concerning ‘klasse’ and ‘klasses’ in the model.  
Added inflection “inflect.irregular ‘klasse’, ‘klassen’” to  
inflections.rb.  
Recreated model again using scaffold.

URL: [http://localhost:3000/klassen](http://localhost:3000/klassen) fails with the following:

Mysql::Error: #42S02Table ‘schule\_development.klasses’ doesn’t exist:  
SELECT \* FROM `klasses`

Seems rails is still hanging onto ‘klasses’ somewhere, but where?

Any ideas anyone?

Did you check all the files created by your scaffold, including the  
migrations? Also if you change the inflections, you should restart  
your environment (stop/start the server) before they are applied.

Seems like you still have the older migration (klasses) applied to your  
database.

Reapply the migration

rake db:migrate VERSION=0  
rake db:migrate

My bad, please ignore my previous message. Did you restart the server  
after  
adding your custom inflection rule.
