Answer 1

Just trying to check on the obvious here, but have you tried running rake db:drop? Whenever I make changes to my migrations, I need to drop all of my DB tables before I try to create and migrate them.

So the full operation would be rake db:drop db:create db:migrate

Oh, and you can also try to specify the environment (I sometimes need to do that on test environments), e.g. rake RAILS_ENV=test db:drop db:create db:migrate

The Routes file in Rails uses device_for, which loads the User model, which in turn has acts_as_messagable and loads the Message class. Line #29 in Message class says:

scope :unread, where('reciever_open = false')

The where method is triggering a column lookup, which fails because the migrations haven't run yet! Try one of these two:

Change this to:

scope :unread, where(:reciever_open => false)

Or if that also triggers a column lookup, then say:

scope :unread, lambda { where('reciever_open = false') }
