Recovering stashes that were cleared/dropped erroneously
If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
following incantation to get a list of stashes that are still in your repository, but not reachable any more:
git fsck --unreachable |
grep commit | cut -d\ -f3 |
xargs git log --merges --no-walk --grep=WIP

Alternatives for a full_name method
class User
# Downsides - when first name is nil, you'll have a string like " LastName"
def full_name
"#{first_name} #{last_name}"
end
# Downsides - a bit harder to understand
def full_name
[first_name, last_name].compact.join(' ')
