# This file documents the revision history for Perl extension Catalyst-TraitFor-Request-QueryFromJSONY

0.002 - 2015-10-01
  - Make it easier when you have more then 'q' as JSONY parameters.
  - removed 'has_query_data' method since its no longer useful (could be a
    breaking change for you but easy to work around).
  - Add some callbacks to handle common exception conditions, like when
    JSONY can't parse the values, or the value doesn't exist.
  - Change to Moo from Moose (won't have any impact on code now, but if
    Catalyst ever moves bits to Moo, this we be better preparation).

This role defines the following methods.

## query\_data (?@query\_params, ?\\%options)

For each item in @query\_params that exists in $request->query\_parameters deserialize
using [JSONY](https://metacpan.org/pod/JSONY)  and return the data references (could be a hashref, or arrayref 
depending on the query construction.

If no @query\_params are submitted, assume 'q' as the default.

The %options hash allows you to set callback to handle exceptional conditions. All callbacks
get invoked with two parameters, the current $request object, and the name of the
query parameter that caused the condition.  For example the follow substitutes the string
'\[\]' when a $key is missing from %{$c->req->query\_parameters}:

    $c->req->query_data(qw/a b c/, +{ 
      param_missing => sub {
        my ($req, $key) = @_;
        return '[]';
      }
    });
