NAME

RT::Extension::ConditionalCustomFields - CF conditionned by the value of another CF

DESCRIPTION

Provide the ability to display/edit a custom field conditioned by the value of another (select) custom field for the same object, which can be anything that can have custom fields (ticket, queue, user, group, article or asset).

If a custom field is based on another (parent) custom field which is conditioned by, this (child) custom field will of course also be conditioned by (with the same condition as its parent).

If the condition custom field is a multivalued select, the condition for an object is met as soon as the condition is met by at least one value of the instanciated custom field for this object.

From version 0.07, the condition can be multivalued, that is: the conditioned custom field can be displayed/edited if the condition custom field has one of these values (In other words: there is an OR bewteen the values of the condition). The condition custom field can be a select custom field with values defined by CustomFieldValues or an external custom field.

Note that version 0.07 is a complete redesign: the API described below has changed; also, the way that ConditionedBy property is store has changed. If you upgrade from a previous version, you have to reconfigure the custom fields which are conditionned by.

RT VERSION

Works with RT 4.2 or greater

INSTALLATION

Patch your RT

ConditionalCustomFields requires a small patch to add necessary Callbacks on versions of RT superior to 4.2.3. (The patch has been submitted to BestPractical in order to be included in future RT releases, as of RT 4.4.2, some parts of the patch are already included, but some other parts still required to apply this patch.)

For RT 4.2, apply the included patch:

cd /opt/rt4 # Your location may be different
patch -p1 < /download/dir/RT-Extension-ConditionalCustomFields/patches/4.2-add-callbacks-to-extend-customfields-capabilities.patch

For RT 4.4.1, apply the included patch:

cd /opt/rt4 # Your location may be different
patch -p1 < /download/dir/RT-Extension-ConditionalCustomFields/patches/4.4.1-add-callbacks-to-extend-customfields-capabilities.patch

For RT 4.4.2, apply the included patch:

cd /opt/rt4 # Your location may be different
patch -p1 < /download/dir/RT-Extension-ConditionalCustomFields/patches/4.4.2-add-callbacks-to-extend-customfields-capabilities.patch
Edit your /opt/rt4/etc/RT_SiteConfig.pm

If you are using RT 4.2 or greater, add this line:

Plugin('RT::Extension::ConditionalCustomFields');

For RT 4.0, add this line:

Set(@Plugins, qw(RT::Extension::ConditionalCustomFields));

or add RT::Extension::ConditionalCustomFields to your existing @Plugins line.

METHODS

ConditionalCustomFields adds a ConditionedBy property, that is a CustomField and a value, along with the following methods, to RT::CustomField objets:

SetConditionedBy CF, VALUE

Set the ConditionedBy property for this CustomField object to CustomFieldValue CF with value set to VALUE. CF should be an existing CustomField object or the id of an existing CustomField object, or the name of an unambiguous existing CustomField object. VALUE should be a string. Current user should have SeeCustomField and ModifyCustomField rights for this CustomField and SeeCustomField right for the CustomField which this CustomField is conditionned by. Returns (1, 'Status message') on success and (0, 'Error Message') on failure.

ConditionedBy

Returns the current ConditionedBy property for this CustomField object as a hash with keys CF containing the id of the CustomField which this CustomField is recursively conditionned by, and val containing the value as string. If neither this CustomField object nor one of its ancestor is conditioned by another one, that is: if their ConditionedBy property is not (recursively) defined, returns undef. Current user should have SeeCustomField right for both this CustomField and the CustomField which this CustomField is conditionned recursively by. "Recursively" means that this method will search for a ConditionedBy property for this CustomField object, then for the CustomField this one is BasedOn, and so on until it find an acestor Category with a ConditionedBy property or, the CustomField which is being looked up, is not based on any ancestor Category.

INITIALDATA

Also, ConditionalCustomFields allows to set the ConditionedBy property when creating CustomFields from an initialdata file, with one of the following syntaxes:

@CustomFields = (
    {
        Name => 'Condition',
        Type => 'SelectSingle',
        RenderType => 'Dropdown',
        Queue => [ 'General' ],
        LookupType => 'RT::Queue-RT::Ticket',
        Values => [
            { Name => 'Passed', SortOrder => 0 },
            { Name => 'Failed', SortOrder => 1 },
        ],
        Pattern => '(?#Mandatory).',
        DefaultValues => [ 'Failed' ],
    },
    {
        Name => 'Conditioned with cf name and value',
        Type => 'FreeformSingle',
        Queue => [ 'General' ],
        LookupType => 'RT::Queue-RT::Ticket',
        ConditionedByCF => 'Condition',
        ConditionedBy => 'Passed',
    },
    {
        Name => 'Conditioned with cf id and value',
        Type => 'FreeformSingle',
        Queue => [ 'General' ],
        LookupType => 'RT::Queue-RT::Ticket',
        ConditionedByCF => 66,
        ConditionedBy => 'Passed',
    },
);

This examples creates a select CustomField Condition which should have the value Passed, for CustomFields Conditioned with cf name and value and Conditioned with cf id and value to be displayed or edited.

Additional fields for an element of @CustomFields are:

ConditonedByCF

The CustomField that this new CustomField should conditionned by. It can be either the id or the Name of a previously created CustomField. This implies that this CustomField should be declared before this one in the initialdata file, or it should already exist. When ConditionedByCF attribute is set, ConditionedBy attribute should always also be set.

ConditonedBy

The value as a string of the CustomField defined by the ConditionedByCF attribute (which is mandatory).
