Jifty::Request::Mapper - Maps response values into arbitrary query parameters
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.
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 syntaxes for each key => value pair in the HASH are:
KEY => STRINGThe 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.
Responsible for doing the actual mapping that "query_parameters" above sets up. That is, takes magical query parameters and extracts the values they were ment to have.
The key from a query parameter
The value of a query parameter
The Jifty::Request object to pull action arguments from. Defaults to the current request.
The Jifty::Response object to pull results from. Defaults to the current response.
Returns a key => value pair.
