module ActionController #:nodoc:
|
|
# Actions that fail to perform as expected throw exceptions. These
|
|
# exceptions can either be rescued for the public view (with a nice
|
|
# user-friendly explanation) or for the developers view (with tons of
|
|
# debugging information). The developers view is already implemented by
|
|
# the Action Controller, but the public view should be tailored to your
|
|
# specific application.
|
|
#
|
|
# The default behavior for public exceptions is to render a static html
|
|
# file with the name of the error code thrown. If no such file exists, an
|
|
# empty response is sent with the correct status code.
|
|
#
|
|
# You can override what constitutes a local request by overriding the
|
|
# <tt>local_request?</tt> method in your own controller. Custom rescue
|
|
# behavior is achieved by overriding the <tt>rescue_action_in_public</tt>
|
|
# and <tt>rescue_action_locally</tt> methods.
