Undefined method 'bool' during migration (Rails Heroku Postgres)

Question

I have a locally-developed app that is working fine on postgres, however, once I uploaded it to heroku, I'm receiving an error in the migration:

undefined method `bool' for #<ActiveRecord::ConnectionAdapters::PostgreSQL::TableDefinition:0x007fb335472530>/app/db/migrate/20150603202509_devise_create_admins.rb:5:in `block in change'

Line 5 of the referenced migration:

t.boolean :manage_users, default: false

I didn't have any problems locally, just now that it's on heroku. Using pg v0.18.2

Which versions of postgres and the pg gem are you using? Make sure they are compatible with heroku ;) — Automatico

Using pg v0.18.2 which is the same as another working heroku app. And yes, the migration is being ran on the t.boolean line above, which I too thought was strange because it mentioned the "bool" method. — Wes Foster

I ran into this error too. I did this to cause the error:

$ rails generate scaffold MyObject isGreen:bool

I fixed it by changing bool to boolean:

$ rails generate scaffold MyObject isGreen:boolean
