# Return a response that has no content (merely headers). The options
|
|
# argument is interpreted to be a hash of header names and values.
|
|
# This allows you to easily return a response that consists only of
|
|
# significant headers:
|
|
#
|
|
# head :created, :location => person_path(@person)
|
|
#
|
|
# head :created, :location => @person
|
|
#
|
|
# It can also be used to return exceptional conditions:
|
|
#
|
|
# return head(:method_not_allowed) unless request.post?
|
|
# return head(:bad_request) unless valid_request?
|
|
# render
