=head1 NAME
NGCP::Panel::Controller::Contract - Catalyst Controller
=head1 DESCRIPTION
View and edit Contracts. Optionally filter them by only peering contracts.
=head1 METHODS
=head2 contract_list
Basis for contracts.
=head2 root
Display contracts through F<contract/list.tt> template.
=head2 create
Show modal dialog to create a new contract.
=head2 base
Capture id of existing contract. Used for L</edit> and L</delete>. Stash "contract" and "contract_result".
=head2 edit
Show modal dialog to edit a contract.
=head2 delete
Delete a contract.
=head2 ajax
Get contracts from the database and output them as JSON.
The output format is meant for parsing with datatables.
The selected rows should be billing.billing_mappings JOIN billing.contracts with only one billing_mapping per contract (the one that fits best with the time).
=head2 peering_list
Basis for peering_contracts.
=head2 peering_root
Display contracts through F<contract/list.tt> template. Use L</peering_ajax> as data source.
=head2 peering_ajax
Similar to L</ajax>. Only select contracts, where billing.product is of class "sippeering".
=head2 peering_create
Similar to L</create> but sets product_id of billing_mapping to match the
product of class "sippeering".
