Instance Method Summary

• #brainstem_valid_params(requested_context = action_name.to_sym, root_param_name = brainstem_model_name) ⇒ Hash{String => String, Hash] a hash of pairs of param names and (also: #brainstem_valid_params_for)

  Lists all valid parameters for the current action.

• #transforms(requested_context = action_name.to_sym) ⇒ Hash{Symbol => Symbol} (also: #transforms_for)

  Lists all incoming param keys that will be rewritten to use a different name for internal usage for the current action.

#brainstem_valid_params(requested_context = action_name.to_sym, root_param_name = brainstem_model_name) ⇒ Hash{String => String, Hash] a hash of pairs of param names and Also known as: brainstem_valid_params_for

Lists all valid parameters for the current action. Falls back to the valid parameters for the default context.

Returns:

• (Hash{String => String, Hash] a hash of pairs of param names and) —

      root.to_s == root_param_name.to_s
    end
end

#transforms(requested_context = action_name.to_sym) ⇒ Hash{Symbol => Symbol} Also known as: transforms_for

Lists all incoming param keys that will be rewritten to use a different name for internal usage for the current action.

Rewrites all params to be symbols for backwards compatibility.

Returns:

• (Hash{Symbol => Symbol}) —

  a map of incoming => internal param names.
