Extend given to check against the value #1395
Description
It would be nice to allow a value to be specified on a given so that different parameters could be included for example:
params do
requires :grant_type, type: String, values: [:password, :refresh_token]
requires :client_id, type: String
given :grant_type, value: ->(*) { |attr| attr == :password } do
requires :username, type: String
requires :password, type: String
end
given :grant_type, value: ->(*) { |attr| attr == :refresh_token } do
requires :refresh_token, type: String
end
end
