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

Answer 1

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
