Customizing the display of referenced entities
LinkAhead WebUI supports the customized display of referenced entities
using the ext_references
module. The BUILD_MODULE_EXT_RESOLVE_REFERENCES
build variable has
to be set to ENABLED
(see /getting_started) in order to use
this module.
You may then define your own JavaScript module to define how
references to specific Records should be resolved. The module has to
be located at a directory which is known to LinkAhead WebUI; we recommend
linkahead-webui/src/ext/js
. Set the value of the
BUILD_EXT_REFERENCES_CUSTOM_RESOLVER
build variable to the name of
this module. The module has to have a resolve
function which takes
an entity id as its only parameter and returns a reference_info
object with the resolved custom reference as a text
property. So
the basic structure of the module should look like
var my_reference_resolver = new function () {
// Has to be called ``resolve`` and has to take exactly one
// string parameter: the id of the referenced entity.
this.resolve = async function (id) {
/*
* find the string that the reference should be resolved to,
* e.g., from the value of the entity's properties.
*/
return {"text": new_reference_text}
}
}
An example is located in
linkahead-webui/src/core/js/reference_resolver/linkahead_default_person.js
. It
resolves any reference to a Person
Record to the value of its firstname
and lastname
properties separated by a space and is active by default.
