heroku - Ruby on Rails: Update Attribute -

google failing me right now. need update 1 attribute, setting user admin, heroku rails console.

i can't find single simple answer. i've been trying is:

record.update_attribute(:roles_mask, "1")

where record correct record.

'undefined method 'update attribute''

i can't type record.roles_mask = 1?

edit.

i used record, , shouldn't have done in example. i've done this:

ian = user.where(:id => '5')  ian.update_attribute(:roles_mask, '1')  error: undefined method 'update_attributes'

the problem using .where function creates relation, rather finding record itself. this:

ian = user.find(5) ian.update_attribute(:roles_mask, '1')

or if want use .where this:

ian = user.where(:id => 5) ian.first.update_attribute(:roles_mask, '1')

edit

see this answer details why happening.

And
