Cannot add role with symbol

[MartinJNash]

When I try to add a role with a symbol, I get the following error.

ActiveRecord::AssociationTypeMismatch: Role(#70173822757240) expected, got Symbol(#70173818545420)
from /Users/nash/.rvm/gems/ruby-2.0.0-p353/gems/activerecord-4.1.1/lib/active_record/associations/association.rb:216:in `raise_on_type_mismatch!'

user.add_role :admin

Admin is a valid role

Role.pluck :name  # => ["user", "admin", "editor"]

OMG, I somehow missed this your report @MartinJNash. I will investigate what can be an issue here though I believe this is might not be actual for you anymore.

Sorry for not reacting the moment when your reported this.

+1 on this, having the same error in my seeds.rb.

[gadikotamohan]

+1 when I upgraded rails from 4.1.0 to 4.1.4
