# This method outputs without escaping a string. Since escaping tags is
|
|
# now default, this can be used when you don't want Rails to automatically
|
|
# escape tags. This is not recommended if the data is coming from the user's
|
|
# input.
|
|
#
|
|
# For example:
|
|
#
|
|
# raw @user.name
|
|
# # => 'Jimmy <alert>Tables</alert>'
