How do I add Devise's 'timeoutable' module to an existing Devise install? - Rails 3.1

Question

These are the instructions to add a module to an existing Devise install: https://github.com/plataformatec/devise/wiki/How-To:-change-an-already-existing-table-to-add-devise-required-columns

But I can't seem to locate the necessary columns for timeoutable.

I looked for the fields that timeoutable requires in the Devise library: https://github.com/plataformatec/devise/blob/master/lib/devise/schema.rb - but there is no such method in that schema file.

The model just has a custom method with no reference to the columns: http://rdoc.info/github/plataformatec/devise/master/Devise/Models/Timeoutable

How do I add that functionality?

Thanks.

Answer 1

timeoutable refers to the login session timeout. No extra columns are needed, just add it to your model.

The timeoutable hook contains all the magic (source: https://github.com/plataformatec/devise/blob/master/lib/devise/hooks/timeoutable.rb)

Answer 2

You only need add timeoutable to your user model:

devise :timeoutable

And set the interval time in config/initializers/devise.rb:

# ==> Configuration for :timeoutable
# The time you want to timeout the user session without activity. After this
# time the user will be asked for credentials again. Default is 30 minutes.
config.timeout_in = 30.minutes
