NAME

       Jifty::Request::Mapper - Maps response values into arbitrary query parameters

DESCRIPTION

       "Jifty::Request::Mapper" is used to insert values into parameters that you can't know when you originally constructed the request.  The
       prime example of this is a Create action to a View page -- where you can't know what ID to supply to the View page until after the Create
       action has run.	This problem can be fixed by establishing a mapping between some part of the Jifty::Result of the Create action, and the
       ID query parameter.

METHODS

   query_parameters HASH
       Extended syntax for generating query parameters.  This is used by Jifty::Web::Form::Clickable for its "parameters" argument, as well as for
       "results" of continuations.

       Possible formats for each key => value pair in the "HASH" are:

       "KEY => STRING"
	   The simplest form -- the "KEY" will have the literal value of the "STRING" supplied

       "KEY => { result => ACTION }"
	   The "KEY" will take on the value of the content named "KEY" from the result of the "ACTION".  "ACTION" may either be a Jifty::Action
	   object, or a moniker thereof.

       "KEY => { result => ACTION, name => STRING }"
	   The "KEY" will take on the value of the content named "STRING" from the result of the "ACTION".  "ACTION" may either be a Jifty::Action
	   object, or a moniker thereof.

       "KEY => { request_argument => STRING }"
	   The "KEY" will take on the value of the argument named "STRING" from the request.

       "KEY => { argument => ACTION }"
	   The "KEY" will take on the value of the argument named "KEY" from the "ACTION".  "ACTION" may either be a Jifty::Action object, or a
	   moniker thereof.

       "KEY => { argument => ACTION. name => STRING }"
	   The "KEY" will take on the value of the argument named "STRING" from the "ACTION".  "ACTION" may either be a Jifty::Action object, or a
	   moniker thereof.

       "result_of" and "argument_to" are valid synonyms for "result" and "argument", above.

   map PARAMHASH
       Responsible for doing the actual mapping that "query_parameters" above sets up.	That is, takes magical query parameters and extracts the
       values they were meant to have.

       destination
	   The "key" from a query parameter

       source
	   The "value" of a query parameter

       request
	   The Jifty::Request object to pull action arguments from.  Defaults to the current request.

       response
	   The Jifty::Response object to pull results from.  Defaults to the current response.

       Returns a key => value pair.

NAME

       Jifty::Action::Record::Create - Automagic creation action

DESCRIPTION

       This class is used as the base class for Jifty::Actions that are merely creating Jifty::Record objects.	To use it, subclass it and
       override the "record_class" method to return the name of the Jifty::Record subclass that this action creates.

METHODS

   arguments
       Set the default value in each of the fields to whatever the default of the column is in the model

   take_action
       Overrides the virtual "take_action" method on Jifty::Action to call the appropriate "Jifty::Record"'s "create" method when the action is
       run, thus creating a new object in the database.

       The "id" of the new row is returned in the "id" content of the Jifty::Result for the action.  You can use this in conjunction with request
       mapping in order to give later parts of the request access to the "id".

   create_record
       This method actually performs the call to "record->create". It receives as arguments the parameter hash and should return the message for
       the user, indicating success or failure.

   report_success
       Sets the "message" in Jifty::Result to default success message, "Created". Override this if you want to report some other more user-
       friendly result.

   possible_columns
       Create actions do not provide fields for columns marked as "private" or "protected".

   _extra_validator_args
       Passes "for => 'create'" to validators.

   _extra_canonicalizer_args
       Passes "for => 'create'" to canonicalizers.

   _extra_autocompleter_args
       Passes "for => 'create'" to autocompleters.
