@patriciojofre why call it store_cookie if it can apply to any rule ?
We could have a store_policy_RULE_NAME for every rule initialized in the user concern for example
What do you think ?

[michelson]

I agree with the method naming, however I think we could avoid creating multiple methods and just just add the store_policy_from(name).
This is just a method that wraps the "current_user.handle_policy_for(@term)" with an extra logic were validates the presence of a published term.

[michelson]

since the method accepts a term, we should name it as accept_policy_from

[patriciojofre]

+1 @michelson, create multiples methods for this little wrapper is not necessary.
I'll change the name to accept_policy_from 😄
