# File actionpack/lib/action_controller/metal/parameter_encoding.rb, line 46 def skip_parameter_encoding(action) @_parameter_encodings[action.to_s] = true end
Specify that a given action's parameters should all be encoded as ASCII-8BIT (it “skips” the encoding default of UTF-8).
For example, a controller would use it like this:
class RepositoryController < ActionController::Base skip_parameter_encoding :show def show @repo = Repository.find_by_filesystem_path params[:file_path] # `repo_name` is guaranteed to be UTF-8, but was ASCII-8BIT, so # tag it as such @repo_name = params[:repo_name].force_encoding 'UTF-8' end def index @repositories = Repository.all end end
The show action in the above controller would have all parameter values encoded as ASCII-8BIT. This is useful in the case where an application must handle data but encoding of the data is unknown, like file system data.
