parameters() click to toggle source

Returns both GET and POST parameters in a single hash.

    # File lib/action_dispatch/http/parameters.rb, line 8
 8:       def parameters
 9:         @env["action_dispatch.request.parameters"] ||= begin
10:           params = request_parameters.merge(query_parameters)
11:           params.merge!(path_parameters)
12:           encode_params(params).with_indifferent_access
13:         end
14:       end

Also aliased as: params

params() click to toggle source

Alias for: parameters

path_parameters() click to toggle source

Returns a hash with the parameters used to form the path of the request. Returned hash keys are strings:

  {'action' => 'my_action', 'controller' => 'my_controller'}

See symbolized_path_parameters for symbolized keys.

    # File lib/action_dispatch/http/parameters.rb, line 34
34:       def path_parameters
35:         @env["action_dispatch.request.path_parameters"] ||= {}
36:       end

symbolized_path_parameters() click to toggle source

The same as path_parameters with explicitly symbolized keys.

    # File lib/action_dispatch/http/parameters.rb, line 24
24:       def symbolized_path_parameters
25:         @symbolized_path_params ||= path_parameters.symbolize_keys
26:       end

encode_params(params) click to toggle source

TODO: Validate that the characters are UTF-8. If they aren’t, you’ll get a weird error down the road, but our form handling should really prevent that from happening

    # File lib/action_dispatch/http/parameters.rb, line 43
43:       def encode_params(params)
44:         return params unless "ruby".encoding_aware?

47:           return params.force_encoding("UTF-8").encode!
48:         elsif !params.is_a?(Hash)

50:         end

normalize_parameters(value) click to toggle source

Convert nested Hash to HashWithIndifferentAccess

    # File lib/action_dispatch/http/parameters.rb, line 65
65:       def normalize_parameters(value)
66:         case value
67:         when Hash

69:           value.each { |k, v| h[k] = normalize_parameters(v) }
70:           h.with_indifferent_access
71:         when Array
72:           value.map { |e| normalize_parameters(e) }
73:         else
74:           value
75:         end
