NAME ^

Catalyst::Controller::DBIC::API::StaticArguments - Provides controller level configuration arguments

VERSION ^

version 2.004004

DESCRIPTION ^

StaticArguments is a Role that is composed by the controller to provide configuration parameters such as how where in the request data to find specific elements, and if to use JSON boolean types.

PUBLIC_ATTRIBUTES ^

create_requires create_allows update_requires update_allows

These attributes control requirements and limits to columns when creating or updating objects.

Each provides a number of handles:

    "get_${var}_column" => 'get'
    "set_${var}_column" => 'set'
    "delete_${var}_column" => 'delete'
    "insert_${var}_column" => 'insert'
    "count_${var}_column" => 'count'
    "all_${var}_columns" => 'elements'

prefetch_allows is: ro, isa: ArrayRef[ArrayRef|Str|HashRef]

prefetch_allows limits what relations may be prefetched when executing searches with joins. This is necessary to avoid denial of service attacks in form of queries which would return a large number of data and unwanted disclosure of data.

Like the synopsis in DBIC::API shows, you can declare a "template" of what is allowed (by using an '*'). Each element passed in, will be converted into a Data::DPath and added to the validator.

    prefetch_allows => [ 'cds', { cds => tracks }, { cds => producers } ] # to be explicit
    prefetch_allows => [ 'cds', { cds => '*' } ] # wildcard means the same thing
