=head1 NAME

NGCP::Panel::Utils::Preferences

=head1 DESCRIPTION

Various utils to outsource common tasks in the controllers
regarding voip_preferences.

=head1 METHODS

=head2 load_preference_list

Parameters:
    c - set this to $c
    pref_values - hashref with all values (from voip_x_preferences)
    peer_pref - boolean, only select peer_prefs
    dom_pref - boolean, only select dom_prefs
    usr_pref - boolean, only select dom_prefs

Load preferences and groups. Fill them with pref_values.
Put them to stash as "pref_groups". This will be used in F<helpers/pref_table.tt>.

Also see "Special case rewrite_rule_set" and "Special case ncos and adm_ncos".

=head2 create_preference_form

Parameters:
    c - set this to $c
    pref_rs - a resultset for voip_x_preferences with the specific "x" already set
    enums - arrayref of all relevant enum rows (already filtered by eg. dom_pref)
    base_uri - string, uri of the preferences list
    edit_uri - string, uri to show the preferences edit modal

Use preference and preference_meta from stash and create a form. Process that
form in case the request has be POSTed. Also parse the GET params "delete",
"activate" and "deactivate" in order to operate on maxoccur != 1 preferences.
Put the form to stash as "form".

=head3 Special case rewrite_rule_set

In order to display the preference rewrite_rule_set correctly, the calling
controller must put rwr_sets_rs (as DBIx::Class::ResultSet) and rwr_sets
(for rendering in the template) to stash. A html select will then be displayed
with all the rewrite_rule_sets. Also helper.rewrite_rule_sets needs to be
set in the template (to be used by F<helpers/pref_table.tt>).

On update 4 voip_*_preferences will be created with the attributes
rewrite_callee_in_dpid, rewrite_caller_in_dpid, rewrite_callee_out_dpid,
rewrite_caller_out_dpid, rewrite_callee_lnp_dpid, rewrite_caller_lnp_dpid
(using the helper method set_rewrite_preferences).

For compatibility with ossbss and the www_admin panel, no preference with
the attribute rewrite_rule_set is created and caller_in_dpid is used to
check which rewrite_rule_set is currently set.

=head3 Special case ncos and adm_ncos

Very similar to rewrite_rule_set (see above). The stashed variables are
ncos_levels_rs and ncos_levels. In the template helper.ncos_levels needs to
be set.

The updated preferences are called ncos_id and adm_ncos_id.

=head3 Special case emergency_mapping_container

Very similar to ncos (see above). The stashed variables are
emergency_mapping_containers_rs and emergency_mapping_containers. In the template
helper.ncos_levels needs to be set.

The updated preferences are called ncos_id and adm_ncos_id.

=head3 Special case sound_set and contract_sound_set

This is also similar to rewrite_rule_set and ncos. The stashed variables are
(contract_)sound_sets_rs and (contract_)sound_sets. In the template helper.(contract_)sound_sets needs to
be set.

The preference with the attribute (contract_)sound_set will contain the id of a sound set.

=head3 Special case allowed_ips

Also something special here. The table containing data is
provisioning.voip_allowed_ip_groups.

=head2 set_rewrite_preferences

See "Special case rewrite_rule_set".
