# While having issues with to_partial_path on a view model giving inconsistent results under differing name spaces of controllers
# I use the below to see that the look up path and view paths were on an controller and modify.
# I've never put the below into production. This is merely something I found while experimenting.
# To sort my issue I used the prefixes avaialable and changed name spacing to give correct behaviour
