Koha::Objects::Mixin::ExtendedAttributes
Overwrites the search method to include extended attributes rewrite and dynamic relation accessors
Checks for the presence of extended_attributes in a query
If present, it builds the dynamic extended attributes relations and rewrites the query to include the extended_attributes relation
$self->_get_extended_attributes_entries( $filtered_params, 0 )
Recursive function that returns the rewritten extended_attributes query entries.
Given: [ '-and', [ { 'extended_attributes.code' => 'CODE_1', 'extended_attributes.attribute' => { 'like' => '%Bar%' } }, { 'extended_attributes.attribute' => { 'like' => '%Bar%' }, 'extended_attributes.code' => 'CODE_2' } ] ];
Returns :
[ 'CODE_1', 'CODE_2' ]
$extended_attributes_entries =
_rewrite_related_metadata_query( $params, 'field_id', 'value', @array )
Helper function that rewrites all subsequent extended_attributes queries to match the alias generated by the dbic self left join Take the below example (patrons): [ { "extended_attributes.attribute":{"like":"%123%"}, "extended_attributes.code":"CODE_1" } ], [ { "extended_attributes.attribute":{"like":"%abc%" }, "extended_attributes.code":"CODE_2" } ]
It'll be rewritten as: [ { 'extended_attributes_CODE_1.attribute' => { 'like' => '%123%' }, 'extended_attributes_CODE_1.code' => 'CODE_1' } ], [ { 'extended_attributes_CODE_2.attribute' => { 'like' => '%abc%' }, 'extended_attributes_CODE_2.code' => 'CODE_2' } ]
Method to dynamically add has_many relations for Koha classes that support extended_attributes.
Returns a list of relation accessor names.
